IBM Expands Containers Into the Enterprise

Share this post:

Docker is taking the industry by storm, radically simplifying how to develop, package and run applications by using lightweight containers. This simplification has triggered an explosive growth in Docker adoption.

As Docker gains adoption in the enterprise, IT teams need an integrated platform that includes orchestration, security and application management – and a highly scalable and secure server platform to run on. Enter IBM’s enterprise servers – z Systems, LinuxONE and Power Systems

“There is clear customer demand for Docker solutions on IBM’s highly scalable servers” – Roger Egan, SVP Sales, Docker.

Introducing Docker Enterprise Edition (EE)

Docker is the leading software container platform that makes it easy for developers and sysadmins to package applications inside Linux®  containers. Inspired by the analogy of shipping containers, Docker includes, within the container, all the software an application needs to run. This uniform packaging format, APIs and standard interfaces for DevOps mean that applications can easily be moved between different environments – for example from development to production.

As Docker has grown, its pivotal role in enabling DevOps, microservices and hybrid cloud has become apparent. And unlike virtual machines, Docker containers are lightweight, with faster start-up times and lower resource requirements. Docker accelerates modernization initiatives for all applications, from traditional codebases to modern microservices. This increases agility and security and optimizes costs with full stack portability.

Docker Enterprise Edition (EE), the enterprise container management platform announced earlier this year, provides IT teams the framework and tooling they need to securely orchestrate and manage applications at scale in production. Key Docker EE capabilities include:

  • Subscription with robust tooling, commercial support and certification
  • Integrated container management and orchestration
  • Image security and management through private registry services
  • Security scanning of images before running
  • Granular user management with RBAC and LDAP/AD integration

Docker EE for Linux on IBM z Systems, LinuxONE and Power Systems

To complement the growing container adoption, Docker Enterprise Edition is planned to be available for IBM’s enterprise servers – z Systems, LinuxONE, and Power – bringing scalability, high performance and security to Docker based applications in those environments.

The combined technology provides unique value to enterprises running critical workloads at scale, for example:

Scalability: With up to 141 high-performing cores, up to 10TB of memory, and up to 160 dedicated I/O processors, IBM z Systems and LinuxONE are able to host over 10,000 Docker containers on a single system. Additionally, LinuxONE completed a proof-of-scalability test running more than 1 million simple workload containers.

Performance: Power Systems include a wider and faster memory interface, faster cores with more threads which yield better throughput, and a split-core mode which provides better latency for interactive web style applications.

Security: IBM z Systems and LinuxONE add security isolation between Logical Partitions running Docker instances, along with on-chip cryptography to protect sensitive data. Together these security capabilities complement the new security features of Docker Enterprise Edition.

Some of the most popular workloads running on Power, LinuxONE and z Systems are already moving to containers. For example, WebSphere and DB2 have both released container-based versions for Linux on Power.

In summary

Docker EE for Linux on IBM z Systems, LinuxONE and Linux on Power is built and delivered by Docker, and is planned to be offered through IBM sales channels.

The combination of Docker Enterprise Edition and IBM z Systems, LinuxONE,  and Power Systems enables software developers to scale their container based applications to new heights. It also enables IT operations to provide the security, performance reliability needed by enterprise applications.
