Overview

IBM Enterprise Application Runtimes includes the following WebSphere Application Server editions:

• WebSphere Application Server Network Deployment and Modernized Runtime Extension for Java (includes WebSphere Application Server Network Deployment Liberty)
• WebSphere Application Server (includes WebSphere Application Server Liberty)
• WebSphere Application Server Liberty Core

IBM Enterprise Application Runtimes is the solution of choice for existing on-premises WebSphere Application Server deployments, which are the WebSphere deployments that have powered a good portion of the world's economy for the last 20 years. With IBM Enterprise Application Runtimes, existing applications can remain in place. IBM Enterprise Application Runtimes gives you the flexibility to move between WebSphere editions without additional entitlements.

Whether migrating to the cloud or off of unsupported specifications, new and updated development are covered. WebSphere Application Server Network Deployment and Modernized Runtime Extension for Java provides enterprise operational capability with modern Java support, such as Java 17.

When it is time to transition WebSphere Application Server applications to the cloud, IBM Enterprise Application Runtimes is also the solution of choice. WebSphere Application Server and WebSphere Application Server Network Deployment include the WebSphere Liberty and Open Liberty options. With its extremely small footprint, industry-leading performance, and full Java EE/Jakarta EE and MicroProfile certification, Liberty is an industry standard for deployments in the cloud, whether modernizing existing applications or creating new cloud-based applications. IBM Enterprise Application Runtimes also includes Red Hat Runtimes, a set of open runtimes, tools, and components for developing and maintaining cloud-native applications.

As WebSphere applications migrate to the cloud, it becomes critical to be able to manage the resultant hybrid environment. IBM is focused on hybrid implementations as the vehicle for clients to maximize their competitiveness and business results related to cloud deployments. WebSphere has been a leader in hybrid deployments, with support for all the major public clouds, Kubernetes deployments, and now optimizations for Red Hat OpenShift that establish Liberty as a solution for Java Enterprise Edition and Jakarta Enterprise Edition (Java EE/Jakarta EE) and MicroProfile deployments to Red Hat OpenShift in private or public clouds. In addition to WebSphere management, IBM Enterprise Application Runtimes delivers common services enablement to ensure integration and management capability across the IBM software portfolio, most notably with IBM Cloud Pak® solutions.

IBM Enterprise Application Runtimes is a flexible solution for WebSphere Application Server deployments that can enable organizations to meet current and future requirements. It delivers a broad range of technical portfolio options, the capability to mix and match across options over time without additional purchases, a cloud-friendly Virtual Processor Core (VPC)-based metric, and the latest entitlement options from IBM, including perpetual and subscription options.

IBM Application Modernization Accelerator

IBM Application Modernization Accelerator helps you plan, prioritize, and package your on-premises workloads for modernization. IBM Application Modernization Accelerator provides a visualization of your application estate and dependencies, estimates development costs for the move, prepares a migration plan, configures the IBM Cloud® services, and automates the creation of a project that contains the SaaS configuration. IBM Application Modernization Accelerator can designate a managed Liberty server as a destination, so that your applications can take advantage of modern Java support.

Learn more in the IBM Application Modernization Accelerator documentation.

IBM Application Modernization Accelerator Developer Tools

With IBM Application Modernization Accelerator Developer Tools, you can modernize your WebSphere® Application Server traditional application to Liberty and upgrade your Java runtime.

Learn more in the IBM Application Modernization Accelerator Developer Tools documentation.

IBM Transformation Advisor

IBM Transformation Advisor helps you plan, prioritize, and package your on-premises workloads for modernization. IBM Transformation Advisor gathers preferences about your on-premises and wanted cloud environments and then analyzes existing middleware deployments by using a data collector. After you upload the results of the data collector, you can review recommendations for migrating your applications to different cloud platforms and the estimated effort to migrate and modernize. IBM Transformation Advisor also creates necessary deployment artifacts to accelerate your migration.
