IBM Cloud: A Private Cloud Story

IBM Cloud Private is a reliable and scalable cloud platform that runs on your infrastructure. It’s built on open-source frameworks, like containers, Kubernetes and Cloud Foundry, with common services for self-service deployment, monitoring, logging and security, as well as a IBM portfolio of middleware, data and analytics. With IBM Cloud Private platform, development and administrative teams share a flexible cloud environment behind their firewalls to create new microservices-based applications, modernize existing apps using cloud-enabled middleware and securely integrate between the two. IBM Cloud Private complements the IBM Cloud by providing consistent runtimes, services and management capabilities.

IBM Cloud Private has been certified for primary infrastructure (server, network & storage) providers, including Dell, NetApp, Cisco and Lenovo, as well as IBM Power Systems and IBM Z. With a consistent underlying Kuberentes-based platform, IBM has enabled key elements of its existing and new middleware, data and analytics portfolio to take advantage of the platform capabilities, including rapid provisioning and de-provisioning of applications, portability between the enterprise and the cloud, improved resource usage and simplified management. Additionally, IBM provides and supports several key open source technologies, including MongoDB and Postrges. Since the platform is based on open technologies, it allows enterprises to also take advantage of a growing ecosystem of software and services that have been enabled for Kubernetes.

IBM Cloud Private is offered in three pricing tiers: Community Edition, Cloud Native and Enterprise. All three tiers provide an integrated environment for managing containers that includes the Kubernetes container orchestrator platform, a private Docker image repository, a management console, and monitoring frameworks.

  • Single Platform for new cloud native application development and optimization of existing applications
  • Choice of application development models for cloud native development
  • Accelerate application and middleware modernization with catalog of container based middleware, data & analytics
  • Minimize risk by reducing changes to existing applications while leveraging platform and middleware for availability elasticity and cost.
  • Integrate within the enterprise and public cloud using the API Connectivity management
  • Runs on existing hardware on premise to address security, compliance, risk and cost.

Platform Components

IBM Cloud Native Landscape is meant to provide enterprises, organizations, developers and sysadmins guidance on the tools for the Cloud-native products and projects.


  • In a Cloud-native world, databases are meant to be consumed in a “as a Service” model and IBM has tons of enterprise-ready DBaaS such as Cloudant, Compose, and Db2-on-Cloud, all managed and supported with solid SLAs.
  • For monitoring, traceability and logging IBM supports the likes of ELK, Zipkin, and Prometheus stacks alongside IBM Application Performance Management.
  • For persistence and data consistency, IBM provides multiple Cloud-native Storage solutions such as IBM Cloud Object Storage and IBM Spectrum Scale. IBM also supports GlusterFS deployments.
  • For service discovery, ingress, load balancing and service mesh, IBM supports NGINX and more recently, Itsio, an effort led by Google, IBM and Lyft to provide management, security and traffic flow for microservices.

The list below shows the different components that are either IBM branded, used within IBM products such as IBM Cloud Private, IBM Cloud Platform (Public), or supported and backed by IBM either through open source communities or foundations.

Next Generation Application Architectures

Single vendor solutions are a thing of the past and technology, in many forms, drives differentiation and disruption. The era where applications were build leveraging a single framework like a Dot Net for Java EE is legacy and more and more applications need to leverage various tools and frameworks to deliver not just the core services but also innovation and strategic capabilities. This is where a platform like IBM ICP will be the differentiator which encompass capabilities from both worlds i.e Enterprise as well and Open Source. Each of components/framework elements of the IBM ICP platform will bring in different benefits as part of the target architecture providing the differentiation.
