Rackspace Launches PCaaS & Kubernetes Private Cloud

Today at HPE Discover 2018 in Vegas, Rackspace made two pay-as-you-go announcements. The company has partnered with HPE to launch the industry’s first Private Cloud-as-a-Service (PCaaS) powered by VMware. This puts cloud services wherever they are needed. Rackspace also announced the industry’s first ever Kubernetes-as-a-Service (KaaS). Working with HPE, this new KaaS offering allows Kubernetes to be used wherever needed as well. 

Pay-as-you-go/grow services have really been taking off over the last few years and by 2020 80% of IT infrastructure will be consumed this way (according to IDC). Companies are embracing this model for the cost benefits as well as the flexibility. IT is better able to tackle erratic growth patterns when they only need to pay for what they are using. 

Rackspace’ PCaaS solutions give customers the advantage of both private and public clouds while delivering up to 40% cost savings for many workloads. PCaaS can also give companies an easier path of migration to the cloud. All the while PCaaS can give users improved data control. 

The new Rackspace Private Cloud powered by VMware (RPC-V) with pay per use service and scalability features:

  • Better Economics: Leveraging HPE GreenLake Flexible Capacity, customers only pay for what they use in an on-demand consumption model for infrastructure. This enables private cloud customers to more closely align resources to growth and handle burst capacity and traffic spikes without needing to pay for additional fixed capacity. Enterprises may see savings of up to 40 percent or more using RPC-V compared to alternative methods used to build and operate private clouds.
  • A More Successful Path to Cloud: RPC-V provides an easier and safer migration path that doesn’t require costly and time-consuming application refactoring and allows organizations to continue leveraging their existing application ecosystem.
  • Public Cloud Benefits: Enterprises receive the benefits of a public cloud, including cloud-like utility pricing, elastic infrastructure and simplified IT in a private cloud environment located wherever they need - in their datacenter, a colocation facility or a data center managed by Rackspace.
  • Private Cloud-as-a-Service Benefits: The benefits of PCaaS include superior economics, ease of migration, and data control for most enterprise applications. PCaaS adds more value by relieving the IT team of its operational burden and enabling accelerated innovation, application development and agility.
  • Instant Scalability: Customers can increase their total cloud capacity on-demand, maintaining the performance benefits of a private cloud environment, while instantly scaling their entire private cloud capacity in a public cloud-like manner.

Kubernetes-as-a-Service (KaaS) offer many of the above benefits allowing companies to take full advantage of Kubernetes. Other benefits to customers include:

  • Pay-as-you-go Service: Leveraging HPE GreenLake Flex Capacity, customers pay for what they use in an on-demand consumption model for infrastructure. This feature enables customers to more closely align resources without the need to pay for additional fixed capacity. This flexible capacity model allows customers to take full advantage of the instant enterprise-level scalability of Kubernetes.
  • Agility, Scalability and Strategic Flexibility: Customers maintain the architectural and data control benefits of a private cloud environment, while instantly scaling their entire private cloud capacity in a public cloud-like manner. And, because this solution is fully open-source using upstream Kubernetes, customers will avoid vendor lock-in.  Finally, customers will have the flexibility to scale their Kubernetes environments at their own pace in nearly any data center in the world, including the customer data center, Rackspace data center or third-party colocation facility. 
  • Transformed “Day 2” Operations: Rackspace helps ensure the successful transformation to container-based workloads.  In addition to getting customers up and running quickly and easily, Rackspace goes a step further by managing ongoing “Day 2” operations for customers, including updates, zero downtime upgrades, patching and security hardening for Kubernetes, all managed cluster services and the node operating system.  These operations are the lynchpin to realize success with containers and require extensive skill and experience to implement successfully in production.
  • Enterprise-Grade Security: From the infrastructure to the cluster itself, including the containers running inside the cluster and additional services required to run the application, Rackspace secures Kubernetes-as-a-Service using industry best practices. Rackspace experts fully validate and vet each component of the service, provide static container scanning and ensure only authorized users can access the environment. Rackspace has the people, processes and technology in place to help customers meet security, compliance and data sovereignty needs. 


Rackspace Private Cloud powered by VMware is expected to be available in Summer 2018. Kubernetes-as-a-Service will be available in all regions in June 2018.
