Private cloud vs public cloud

Private cloud is a cloud computing model operated solely for a single organization. It can be managed internally or by a third party, and it can be hosted behind the company firewall or externally. Private cloud offers the benefits of a public cloud, including rapid deployment and scalability plus ease of use and elasticity, but private cloud gives organizations greater control, increased performance, predictable costs, tighter security and flexible management options. A private cloud allows companies to customize their environment according to their unique needs and security requirements.

The IBM perspective: IBM Cloud Private

Many organizations have heard about the promise of cloud to help their teams deliver faster and meet demands, but they feel constrained by regulatory and legal requirements. IBM believes that you do not have to choose between cloud and security. We have released IBM Cloud Private to give you the power of cloud while protecting your resources — without compromise.


Whether optimizing traditional apps and services or creating new cloud-native microservices, your teams benefit from a private cloud built with an enterprise focus on speed, flexibility, control and intelligence along with access to modern cloud services. A self-service catalog enables them to automate the deployment, integration and management of applications and services at the push of a button.

The platform

The core platform is built on Kubernetes, the industry-leading container orchestration platform that works across private, dedicated and public clouds. IBM Cloud delivers a choice of open source application runtimes, Kubernetes and containers or Cloud Foundry. Clients can choose the prescriptive development approach of Cloud Foundry, or the more customizable and portable approach of Kubernetes and Docker containers.

A core set of management services for the application runtime frameworks and the applications being developed is included as part of the platform.  Some examples include logging, monitoring, access control and event management.  Customers can use these management tools integrated with the platform out-of-the-box. If needed, these tools can be integrated with enterprise instances, so that all of the management needs are operationalized from one location.

Software and services

Application services are runtimes, middleware, data and other services that can be added to cloud-native applications or connected to existing applications. IBM Cloud Private makes it easy to stand up an elastic runtime that is based on a variety of workloads. Built in are both open source and IBM middleware and databases that enterprises need to build applications quickly and securely. 

Along with capabilities to build and run enterprise workloads, IBM Cloud Private delivers enhanced support to run CPU-intensive capabilities like machine learning or data analytics quickly by taking advantage of GPU clusters.

All of these application services have been built or re-imagined for cloud-native workloads and are informed by IBM’s long history and experience with enterprise workloads.
