Three distinguishing characteristics of modern on-premises cloud platforms

A critical component of the hybrid cloud platform is establishing an on-premises or private cloud to bridge the gap between traditional IT delivery and a public cloud, for workloads that can benefit from a cloud delivery model but need to remain on-premises.

The private cloud helps ensure the public cloud is exploited for appropriate workloads while maintaining traditional IT delivery for business-critical legacy applications, which can be optimized in place as needed. Rather than create a “competing” platform, the establishment of a private cloud creates a new center of gravity designed to naturally shift demand from existing infrastructure and shadow IT to a faster, less expensive and more capable alternative.

The on-premises or private cloud provides a cloud-like experience, while removing the constraints of traditional service delivery. It has three characteristics that distinguish it from previous virtualized environments:

  1. Infrastructure shifts to flexible converged and hyperconverged platforms and software-defined infrastructure services, replacing specialized, expensive servers and SAN infrastructures. Storage, computing and memory can be provisioned into blocks of computing resources via APIs as needed and can be billed on a usage basis.
  2. Provisioning shifts from manual to automatic. Self-provisioning allows business units to request resources and build environments on demand. Automation and platform services make it possible to support important advances in continuous application development and delivery. DevOps, which requires tight integration between development and testing resources and the business, relies on the ability to rapidly deploy and maintain applications in different environments.
  3. Workload management shifts from static to dynamic and elastic. A major advance in platform design is the ability to move workloads between clusters of computing resources based on rules or on conditions that are detected when a workload is running. This allows the system to strike just the right balance, providing the amount of computing resources and agility necessary to maintain a specified quality-of-service level without overcommitting resources during workload changes.

With a hybrid cloud platform, workloads can be shifted between private and public infrastructure for policy, flexibility and scale. The hybrid cloud platform represents a significant shift in infrastructure strategy — but it doesn’t have to disrupt current systems, which means this approach can be a positive initial step as part of a digital transformation or can be deployed as a solution to a discrete business requirement.
