Rackspace\u2019s latest project is called Private Cloud Everywhere and is a collaboration with VMware to offer what it calls Private Cloud as a Service (PCaaS), making on-demand provisioning of virtualized servers available at most colocation facilities and data centers.\nPCaaS basically means provisioning data center hardware the same way you would on Amazon Web Services, Microsoft Azure or Google Cloud, but instead of using the cloud providers, you use your own hardware, use Rackspace data centers, or set it up in a third-party colocation facility.\n\nBecause customers have the option of deploying a private cloud wherever they want physically, it can help with data sovereignty requirements, such as rules in Europe that restrict data inside national borders.\nRackspace Build-Operate-Transfer program helps with migration to the cloud\nRackspace also offers its Build-Operate-Transfer (BOT) program for customers that want to delay or stagger their migration of on-premises services to the cloud. Rackspace BOT implements a structure knowledge transfer process, giving customers a gradual migration to the cloud while under the supervision of Rackspace cloud experts.\nRackspace is backing this up with service-level agreements that include a 99.99 percent API uptime guarantee, a 100 percent network uptime guarantee, a 15-minute live response time to emergency tickets, and 24x7x365 access to cloud experts.\nThe company claims customers can save up to 39 percent against building their own private clouds, and it offers a choice between CAPEX and OPEX financing.\nRackspace bare-metal cloud offering\nSeparately, Rackspace has launched a bare-metal cloud offering, going into competition with IBM, Oracle, and a host of second-tier cloud providers. Bare-metal offerings means no virtualization or operating environment. The customer must provide everything from the OS layer up.\nThe chief contrast of bare metal to cloud services from Amazon, Microsoft, and Google is those cloud providers put customers in virtualized, multi-tenant environments. Rackspace bare-metal customers (and those of other bare-metal providers) can self-provision dedicated compute, network, and storage equipment within a physically isolated environment with no shared resources or hypervisor overhead.\nThis helps customers comply with data sovereignty requirements and provides a consistent level of performance for I\/O-intensive and latency-sensitive workloads. Rackspace\u2019s bare-metal instances offer NVMe-based SSD for high data throughput and GPU acceleration for high-performance and AI applications.\nOne of the more popular uses for bare-metal offerings is what\u2019s called \u201clift and shift,\u201d where customers take their on-premises environment and move it entirely to the provider. If you have a custom environment, or your apps need special hardware access, moving to a virtualized cloud provider like AWS can be difficult if not impossible.\nIn a bare-metal scenario, you provide your own environment and can choose the hardware, from the amount of CPU cores to memory and network. You also can access the hardware directly, such as the network controller. So, it\u2019s easier to move your entire custom operation unchanged to bare metal than a virtualized environment.\nRackspace\u2019s bare-metal services offer pay-as-you-go pricing, so customers pay for what they use in an on-demand consumption model. The service also offers an on-demand provisioning options to quickly scale up or down infrastructure as needed.
