All EPOC16 devices featured an -family processor and a bit architecture. EPOC16 was a single-user preemptive multitasking operating system, written in Intel assembly language and C and designed to be delivered in read-only memory ROM. It supported a simple programming language named Open Programming Language OPL and an integrated development environment IDE named OVAL. SIBO devices included the: MC, MC, Series 3 —98 , Series 3a, Series 3c, Series 3mx, Siena, Workabout, and Workabout mx.

The MC and MC, the first EPOC16 devices, shipped in The first version of EPOC32, Release 1 appeared on the Psion Series 5 ROM v1. Later, ROM v1.

Release 2 was never publicly available. Work started on the bit version in late The OS was renamed Symbian OS and envisioned as the base for a new range of smartphones. This release is sometimes called ER6. First shipped in This is an important Symbian release which appeared with all contemporary user interfaces including UIQ Sony Ericsson P, P, P, Motorola A, A , Series 80 Nokia , , Series 90 Nokia , Series 60 Nokia , , , , as well as several FOMA phones in Japan.

It also added EDGE support and IPv6. Java support was changed from pJava and JavaPhone to one based on the Java ME standard. First shipped in , one of its advantages would have been a choice of two different kernels EKA1 or EKA2. However, the EKA2 kernel version did not ship until Symbian OS 8. The kernels behave more or less identically from user-side, but are internally very different. EKA1 was chosen by some manufacturers to maintain compatibility with old device drivers, while EKA2 was a real-time kernel.

An improved version of 8. The 8. It was de-productised in Released early It includes many new security related features, including platform security module facilitating mandatory code signing.

The new ARM EABI binary model means developers need to retool and the security changes mean they may have to recode. S60 platform 3rd Edition phones have Symbian OS 9. Sony Ericsson is shipping the M and P based on Symbian OS 9. The earlier versions had a defect where the phone hangs temporarily after the owner sent a large number of SMS'es.

However, on 13 September , Nokia released a small program to fix this defect. Released Q1 Support for OMA Device Management 1. Vietnamese language support. S60 3rd Edition Feature Pack 1 phones have Symbian OS 9. Released on 12 July Upgrades include improved memory management and native support for Wifi The Nokia E72 , Nokia XpressMusic , Nokia N79 , Nokia N96 , Nokia E52 , Nokia E75 , Nokia XpressMusic , Sony Ericsson P1 and others feature Symbian OS 9.

Announced in March Provides the concept of demand paging which is available from v9. Additionally, SQL support is provided by SQLite. Ships with the Samsung i Omnia HD , Nokia N97 , Nokia N97 mini , Nokia XpressMusic , Nokia XpressMusic , Nokia , Nokia , Nokia , Nokia , Nokia C , Nokia X6 , Sony Ericsson Satio , Sony Ericsson Vivaz and Sony Ericsson Vivaz Pro. In the summer of videos showing an early leaked version of Symbian Belle original name of Nokia Belle running on a Nokia N8 were published on YouTube.

Allow the guest to bring up a maximum of M vCPUs. List of host CPUs the guest is allowed to use. Default is no pinning at all more on this below. A CPULIST may be specified as follows:. To allow all the vCPUs of the guest to run on CPUs 0,2,3,5. To allow all the vCPUs of the guest to run on the CPUs from NUMA nodes 0,1,3 of the host. So, if CPUs belong to node 0, CPUs belong to node 1, CPUs to node 2 and CPUs to node 3, the above would mean all the vCPUs of the guest would be allowed to run on CPUs , Combining this notation with the one above is possible.

Following the same example as above, that would be CPUs 1,4,5,7. To ask for specific vCPU mapping. That means in this example , vCPU 0 of the guest will run on CPU 2 of the host and vCPU 1 of the guest will run on CPUs 3,4,6,7,8 of the host excluding CPU 5. More complex notation can be also used, exactly as described above. If this option is not specified, no vCPU to CPU pinning is established, and the vCPUs of the guest can run on all the CPUs of the host.

When using the credit scheduler, this means what CPUs the vCPUs of the domain prefer. If this option is not specified, the vCPUs of the guest will not have any preference regarding host CPUs. A heuristic approach is used for choosing the best node or set of nodes , with the goal of maximizing performance for the guest and, at the same time, achieving efficient utilization of host CPUs and memory.

In that case, the soft affinity of all the vCPUs of the domain will be set to host CPUs belonging to NUMA nodes chosen during placement. A domain with a weight of will get twice as much CPU as a domain with a weight of on a contended host. Legal weights range from 1 to and the default is Honoured by the credit and credit2 schedulers. The cap optionally fixes the maximum amount of CPU a domain will be able to consume, even if the host system has idle CPU cycles.

The cap is expressed as a percentage of one physical CPU: is 1 physical CPU, 50 is half a CPU, is 4 CPUs, etc. The default, 0, means there is no cap. This can be done in the operating system, but can also sometimes be done below the operating system, in the BIOS.

If you are not getting the performance you expect, look at performance and CPU frequency options in your operating system and your BIOS. Specifies the maximum amount of memory a guest can ever see. A "pre-ballooned" HVM guest needs a balloon driver, without a balloon driver it will crash. NOTE : Because of the way ballooning works, the guest has to allocate memory to keep track of maxmem pages, regardless of how much memory it actually has available to it. Specify virtual NUMA configuration with positional arguments.

Note that virtual NUMA is not supported for PV guests yet, because there is an issue with the CPUID instruction handling that affects PV virtual NUMA. Furthermore, guests with virtual NUMA cannot be saved or migrated because the migration stream does not preserve node information. Specifies the size of this virtual node. Specifies which vCPUs belong to this node. Specifies the virtual distance from this node to all nodes including itself with positional arguments.

The number of arguments supplied must match the total number of vnodes. Normally you can use the values from xl info -n or numactl --hardware to fill the vdistances list.

rename the domain which terminated, and then immediately create a new domain with the same configuration as the original. Reset all Xen specific interfaces for the Xen-aware HVM domain allowing it to reestablish these interfaces and continue executing the domain. PV and non-Xen-aware HVM guests are not supported. Action to take if the domain shuts down with a reason code requesting a reboot.

Default is restart. Action to take if the domain shuts down due to a Xen watchdog timeout. Default is destroy. Action to take if the domain performs a 'soft reset' e. does kexec. Default is soft-reset. Direct kernel boot allows booting guests with a kernel and an initrd stored on a filesystem available to the host physical machine, allowing command line arguments to be passed directly. PV guest direct kernel boot is supported. HVM guest direct kernel boot is supported with some limitations it's supported when using qemu-xen and the default BIOS 'seabios', but not supported in case of using stubdom-dm and the old 'rombios'.

Append STRING to the kernel command line. Note: the meaning of this is guest specific. Non direct kernel boot allows booting guests with a firmware. This can be used by all types of guests, although the selection of options is different depending on the guest type.

This option provides the flexibly of letting the guest decide which kernel they want to boot, while preventing having to poke at the guest file system form the toolstack domain. Boots a guest using a para-virtualized version of grub that runs inside of the guest.

The bitness of the guest needs to be know, so that the right version of pvgrub can be selected. Note that xl expects to find the pvgrub bin and pvgrub Currently there's no firmware available for PVH guests, they should be booted using the Direct Kernel Boot method or the bootloader option. Whether to boot this guest as a PV guest within a PVH container. Ie, the guest will experience a PV environment, but processor hardware extensions are used to separate its address space to mitigate the Meltdown attack CVE The PV shim is a specially-built firmware-like executable constructed from the hypervisor source tree.

This option specifies to use a non-default shim. Ignored if pvhsim is false. Command line for the shim. Extra command line arguments for the shim. Default is empty. Specify an XSM security label used for this domain temporarily during its build.

The domain's XSM label will be changed to the execution seclabel specified by seclabel once the build is complete, prior to unpausing the domain. Specify the maximum number of grant frames the domain is allowed to have. This value controls how many pages the domain is able to grant access to for other domains, needed e. for the operation of paravirtualized devices. The default is settable via xl. conf 5. Specify the maximum number of grant maptrack frames the domain is allowed to have.

This value controls how many pages of foreign domains can be accessed via the grant mechanism by this domain. The default value is settable via xl. Specify the maximum grant table version the domain is allowed to use. Disable migration of this domain. This enables certain other features which are incompatible with migration. Currently this is limited to enabling the invariant TSC feature flag in CPUID results when TSC is not emulated.

Specify that this domain is a driver domain. This enables certain features needed in order to run a driver domain. Specify a partial device tree compiled via the Device Tree Compiler.

Given the complexity of verifying the validity of a device tree, this option should only be used with a trusted device tree. Note that the partial device tree should avoid using the phandle which is reserved by the toolstack.

Specify whether IOMMU mappings are enabled for the domain and hence whether it will be enabled for passthrough hardware. Valid values for this option are:. This option is the default if no passthrough hardware is specified in the domain's configuration. This option enables IOMMU mappings and selects an appropriate default operating mode see below for details of the operating modes.

This option is the default if passthrough hardware is specified in the domain's configuration. This option means that IOMMU mappings will be synchronized with the domain's P2M table as follows:.

For a PV domain, all writable pages assigned to the domain are identity mapped by MFN in the IOMMU page table. Thus a device driver running in the domain may program passthrough hardware for DMA using MFN values i. Thus a device driver running in the domain may program passthrough hardware using GFN values i.

guest physical frame numbers without any further translation. This option is unavailable for a PV domain. However, the availability of this option is hardware specific. The default, which chooses between disabled and enabled according to whether passthrough devices are enabled in the config file.

If this option is true the xenstore path for the domain's suspend event channel will not be created. Instead the old xend behaviour of making the whole xenstore device sub-tree writable by the domain will be re-instated. The existence of the suspend event channel path can cause problems with certain PV drivers running in the guest e. old Red Hat PV drivers for Windows.

Specifies the size of vmtrace buffer that would be allocated for each vCPU belonging to this domain. Disabled i. NOTE : Acceptable values are platform specific. For Intel Processor Trace, this value must be a power of 2 between 4k and 16M. The PMU registers are not virtualized and the physical registers are directly accessible when this parameter is enabled. vPMU, by design and purpose, exposes system level performance information to the guest.

Only to be used by sufficiently privileged domains. This feature is currently in experimental state. The following options define the paravirtual, emulated and physical devices which the guest will contain. Specifies the disks both emulated disks and Xen virtual block devices which are to be provided to the guest, and what objects on the host they should map to. See xl-disk-configuration 5 for more details.

Specifies the network interfaces both emulated network adapters, and Xen virtual interfaces which are to be provided to the guest. See xl-network-configuration 5 for more details. Specifies the Virtual Trusted Platform module to be provided to the guest. See xen-vtpm 7 for more details. Specifies the backend domain name or id. This value is required! If this domain is a guest, the backend should be set to the vTPM domain name.

If this domain is a vTPM, the backend should be set to the vTPM manager domain name. Specifies the UUID of this vTPM device. The UUID is used to uniquely identify the vTPM device. You can create one using the uuidgen 1 program on unix systems. If left unspecified, a new UUID will be randomly generated every time the domain boots. If this is a vTPM domain, you should specify a value.

The value is optional if this is a guest domain. Only "none" is supported today, which means that the files are stored using the same credentials as those they have in the guest no user ownership squash or remap. Creates a Xen pvcalls connection to handle pvcalls requests from frontend to backend.

It can be used as an alternative networking model. This option does not control the emulated graphics card presented to an HVM guest. See Emulated VGA Graphics Device below for how to configure the emulated device. If Emulated VGA Graphics Device options are used in a PV guest configuration, xl will pick up vnc , vnclisten , vncpasswd , vncdisplay , vncunused , sdl , opengl and keymap to construct the paravirtual framebuffer device for the guest.

Allow access to the display via the VNC protocol. This enables the other VNC-related settings. Default is 1 enabled. Requests that the VNC display setup searches for a free TCP port to use. The actual display used can be accessed with xl vncviewer. Specifies the password for the VNC server. If the password is set to an empty string, authentication on the VNC server will be disabled, allowing any user to connect. Specifies that the display should be presented via an X window using Simple DirectMedia Layer.

The default is 0 not enabled. Specifies the path to the X authority file that should be used to connect to the X server when the sdl option is used. Enable OpenGL acceleration of the SDL display. The default is 0 disabled. Configure the keymap to use for the keyboard associated with this display. If the input method does not easily support raw keycodes e. this is often the case when using VNC then this allows us to correctly map the input keys into keycodes seen by the guest.

The specific values which are accepted are defined by the version of the device-model which you are using. See Keymaps below or consult the qemu 1 manpage. The default is en-us. Specifies the virtual channels to be provided to the guest. A channel is a low-bandwidth, bidirectional byte stream, which resembles a serial link.

Typical uses for channels include transmitting VM configuration after boot and signalling to in-guest agents. Please see xen-pv-channel 7 for more details. Leading and trailing whitespace is ignored in both KEY and VALUE. Defined values are:. This parameter is optional. If this parameter is omitted then the toolstack domain will be assumed. Specifies the name for this device.

This parameter is mandatory! This should be a well-known name for a specific application e. guest agent and should be used by the frontend to connect the application to the right channel device.

There is no formal registry of channel names, so application authors are encouraged to make their names unique by including the domain name and a version number in the string e. The backend will proxy data between the channel and the connected socket. The backend will create a pty and proxy data between the channel and the master device. The command xl channel-list can be used to discover the assigned slave device.

Specifies information about Reserved Device Memory RDM , which is necessary to enable robust device passthrough. One example of RDM is reporting through the ACPI Reserved Memory Region Reporting RMRR structure on the x86 platform.

If set to "host" it means all reserved device memory on this platform should be checked to reserve regions in this VM's address space.

This global RDM parameter allows the user to specify reserved regions explicitly, and using "host" includes all reserved regions reported on this platform, which is useful when doing hotplug. When we look across the Intuit QuickBooks platform and the overall fintech ecosystem, we see a variety of innovations fueled by AI and data science that are helping small businesses succeed.

By efficiently embedding and connecting financial services like banking, payments, and lending to help small businesses, we can reinvent how SMBs get paid and enable greater access to the vital funds they need at critical points in their journey.

Overall, we see fintech as empowering people who have been left behind by antiquated financial systems, giving them real-time insights, tips, and tools they need to turn their financial dreams into a reality. Innovations in payments and financial technologies have helped transform daily life for millions of people. People who are unbanked often rely on more expensive alternative financial products AFPs such as payday loans, money orders, and other expensive credit facilities that typically charge higher fees and interest rates, making it more likely that people have to dip into their savings to stay afloat.

A few examples include:. Mobile wallets - The unbanked may not have traditional bank accounts but can have verified mobile wallet accounts for shopping and bill payments.

Their mobile wallet identity can be used to open a virtual bank account for secure and convenient online banking. Minimal to no-fee banking services - Fintech companies typically have much lower acquisition and operating costs than traditional financial institutions. They are then able to pass on these savings in the form of no-fee or no-minimum-balance products to their customers.

This enables immigrants and other populations that may be underbanked to move up the credit lifecycle to get additional forms of credit such as auto, home and education loans, etc.

Entrepreneurs from every background, in every part of the world, should be empowered to start and scale global businesses. Most businesses still face daunting challenges with very basic matters. These are still very manually intensive processes, and they are barriers to entrepreneurship in the form of paperwork, PDFs, faxes, and forms. Stripe is working to solve these rather mundane and boring challenges, almost always with an application programming interface that simplifies complex processes into a few clicks.

Stripe powers nearly half a million businesses in rural America. The internet economy is just beginning to make a real difference for businesses of all sizes in all kinds of places. We are excited about this future. The way we make decisions on credit should be fair and inclusive and done in a way that takes into account a greater picture of a person.

Lenders can better serve their borrowers with more data and better math. Zest AI has successfully built a compliant, consistent, and equitable AI-automated underwriting technology that lenders can utilize to help make their credit decisions. While artificial intelligence AI systems have been a tool historically used by sophisticated investors to maximize their returns, newer and more advanced AI systems will be the key innovation to democratize access to financial systems in the future.

D espite privacy, ethics, and bias issues that remain to be resolved with AI systems, the good news is that as large r datasets become progressively easier to interconnect, AI and related natural language processing NLP technology innovations are increasingly able to equalize access. T he even better news is that this democratization is taking multiple forms. AI can be used to provide risk assessments necessary to bank those under-served or denied access.

AI systems can also retrieve troves of data not used in traditional credit reports, including personal cash flow, payment applications usage, on-time utility payments, and other data buried within large datasets, to create fair and more accurate risk assessments essential to obtain credit and other financial services. By expanding credit availability to historically underserved communities, AI enables them to gain credit and build wealth.

Additionally, personalized portfolio management will become available to more people with the implementation and advancement of AI. Sophisticated financial advice and routine oversight, typically reserved for traditional investors, will allow individuals, including marginalized and low-income people, to maximize the value of their financial portfolios.

Moreover, when coupled with NLP technologies, even greater democratization can result as inexperienced investors can interact with AI systems in plain English, while providing an easier interface to financial markets than existing execution tools.

Open finance technology enables millions of people to use the apps and services that they rely on to manage their financial lives — from overdraft protection, to money management, investing for retirement, or building credit. More than 8 in 10 Americans are now using digital finance tools powered by open finance. This is because consumers see something they like or want — a new choice, more options, or lower costs.

What is open finance? At its core, it is about putting consumers in control of their own data and allowing them to use it to get a better deal.

When people can easily switch to another company and bring their financial history with them, that presents real competition to legacy services and forces everyone to improve, with positive results for consumers. For example, we see the impact this is having on large players being forced to drop overdraft fees or to compete to deliver products consumers want. We see the benefits of open finance first hand at Plaid, as we support thousands of companies, from the biggest fintechs, to startups, to large and small banks.

All are building products that depend on one thing - consumers' ability to securely share their data to use different services. Open finance has supported more inclusive, competitive financial systems for consumers and small businesses in the U. and across the globe — and there is room to do much more. As an example, the National Consumer Law Consumer recently put out a new report that looked at consumers providing access to their bank account data so their rent payments could inform their mortgage underwriting and help build credit.

This is part of the promise of open finance. At Plaid, we believe a consumer should have a right to their own data, and agency over that data, no matter where it sits. This will be essential to securing benefits of open finance for consumers for many years to come.

As AWS preps for its annual re:Invent conference, Adam Selipsky talks product strategy, support for hybrid environments, and the value of the cloud in uncertain economic times. Donna Goodison dgoodison is Protocol's senior reporter focusing on enterprise infrastructure technology, from the 'Big 3' cloud computing providers to data centers.

She previously covered the public cloud at CRN after 15 years as a business reporter for the Boston Herald. AWS is gearing up for re:Invent, its annual cloud computing conference where announcements this year are expected to focus on its end-to-end data strategy and delivering new industry-specific services.

Both prongs of that are important. But cost-cutting is a reality for many customers given the worldwide economic turmoil, and AWS has seen an increase in customers looking to control their cloud spending. By the way, they should be doing that all the time. The motivation's just a little bit higher in the current economic situation. This interview has been edited and condensed for clarity. Besides the sheer growth of AWS, what do you think has changed the most while you were at Tableau?

Were you surprised by anything? The number of customers who are now deeply deployed on AWS, deployed in the cloud, in a way that's fundamental to their business and fundamental to their success surprised me.

There was a time years ago where there were not that many enterprise CEOs who were well-versed in the cloud. It's not just about deploying technology. The conversation that I most end up having with CEOs is about organizational transformation. It is about how they can put data at the center of their decision-making in a way that most organizations have never actually done in their history.

And it's about using the cloud to innovate more quickly and to drive speed into their organizations. Those are cultural characteristics, not technology characteristics, and those have organizational implications about how they organize and what teams they need to have.

It turns out that while the technology is sophisticated, deploying the technology is arguably the lesser challenge compared with how do you mold and shape the organization to best take advantage of all the benefits that the cloud is providing. How has your experience at Tableau affected AWS and how you think about putting your stamp on AWS?

I, personally, have just spent almost five years deeply immersed in the world of data and analytics and business intelligence, and hopefully I learned something during that time about those topics. I'm able to bring back a real insider's view, if you will, about where that world is heading — data, analytics, databases, machine learning, and how all those things come together, and how you really need to view what's happening with data as an end-to-end story.

It's not about having a point solution for a database or an analytic service, it's really about understanding the flow of data from when it comes into your organization all the way through the other end, where people are collaborating and sharing and making decisions based on that data. AWS has tremendous resources devoted in all these areas. Can you talk about the intersection of data and machine learning and how you see that playing out in the next couple of years?

What we're seeing is three areas really coming together: You've got databases, analytics capabilities, and machine learning, and it's sort of like a Venn diagram with a partial overlap of those three circles.

There are areas of each which are arguably still independent from each other, but there's a very large and a very powerful intersection of the three — to the point where we've actually organized inside of AWS around that and have a single leader for all of those areas to really help bring those together. There's so much data in the world, and the amount of it continues to explode. We were saying that five years ago, and it's even more true today.

The rate of growth is only accelerating. It's a huge opportunity and a huge problem. A lot of people are drowning in their data and don't know how to use it to make decisions. Other organizations have figured out how to use these very powerful technologies to really gain insights rapidly from their data. What we're really trying to do is to look at that end-to-end journey of data and to build really compelling, powerful capabilities and services at each stop in that data journey and then…knit all that together with strong concepts like governance.

By putting good governance in place about who has access to what data and where you want to be careful within those guardrails that you set up, you can then set people free to be creative and to explore all the data that's available to them. AWS has more than services now. Have you hit the peak for that or can you sustain that growth? We're not done building yet, and I don't know when we ever will be.

We continue to both release new services because customers need them and they ask us for them and, at the same time, we've put tremendous effort into adding new capabilities inside of the existing services that we've already built. We don't just build a service and move on.

Inside of each of our services — you can pick any example — we're just adding new capabilities all the time. One of our focuses now is to make sure that we're really helping customers to connect and integrate between our different services. So those kinds of capabilities — both building new services, deepening our feature set within existing services, and integrating across our services — are all really important areas that we'll continue to invest in.

Do customers still want those fundamental building blocks and to piece them together themselves, or do they just want AWS to take care of all that? There's no one-size-fits-all solution to what customers want. It is interesting, and I will say somewhat surprising to me, how much basic capabilities, such as price performance of compute, are still absolutely vital to our customers.

But it's absolutely vital. Part of that is because of the size of datasets and because of the machine learning capabilities which are now being created. They require vast amounts of compute, but nobody will be able to do that compute unless we keep dramatically improving the price performance. We also absolutely have more and more customers who want to interact with AWS at a higher level of abstraction…more at the application layer or broader solutions, and we're putting a lot of energy, a lot of resources, into a number of higher-level solutions.

One of the biggest of those … is Amazon Connect, which is our contact center solution. In minutes or hours or days, you can be up and running with a contact center in the cloud. At the beginning of the pandemic, Barclays … sent all their agents home. In something like 10 days, they got 6, agents up and running on Amazon Connect so they could continue servicing their end customers with customer service. We've built a lot of sophisticated capabilities that are machine learning-based inside of Connect.

We can do call transcription, so that supervisors can help with training agents and services that extract meaning and themes out of those calls. We don't talk about the primitive capabilities that power that, we just talk about the capabilities to transcribe calls and to extract meaning from the calls. It's really important that we provide solutions for customers at all levels of the stack. Given the economic challenges that customers are facing, how is AWS ensuring that enterprises are getting better returns on their cloud investments?

Now's the time to lean into the cloud more than ever, precisely because of the uncertainty. We saw it during the pandemic in early , and we're seeing it again now, which is, the benefits of the cloud only magnify in times of uncertainty.

For example, the one thing which many companies do in challenging economic times is to cut capital expense. For most companies, the cloud represents operating expense, not capital expense. You're not buying servers, you're basically paying per unit of time or unit of storage. That provides tremendous flexibility for many companies who just don't have the CapEx in their budgets to still be able to get important, innovation-driving projects done.

Another huge benefit of the cloud is the flexibility that it provides — the elasticity, the ability to dramatically raise or dramatically shrink the amount of resources that are consumed. You can only imagine if a company was in their own data centers, how hard that would have been to grow that quickly.

The ability to dramatically grow or dramatically shrink your IT spend essentially is a unique feature of the cloud. These kinds of challenging times are exactly when you want to prepare yourself to be the innovators … to reinvigorate and reinvest and drive growth forward again. We've seen so many customers who have prepared themselves, are using AWS, and then when a challenge hits, are actually able to accelerate because they've got competitors who are not as prepared, or there's a new opportunity that they spot.

We see a lot of customers actually leaning into their cloud journeys during these uncertain economic times. Do you still push multi-year contracts, and when there's times like this, do customers have the ability to renegotiate?

Many are rapidly accelerating their journey to the cloud. Some customers are doing some belt-tightening. What we see a lot of is folks just being really focused on optimizing their resources, making sure that they're shutting down resources which they're not consuming.

You do see some discretionary projects which are being not canceled, but pushed out. Every customer is free to make that choice. But of course, many of our larger customers want to make longer-term commitments, want to have a deeper relationship with us, want the economics that come with that commitment.
