Enterprise Java apps have been powering mission-critical workloads for decades, but modernizing those apps? That’s often where teams get stuck.

Between maintaining aging infrastructure, navigating complex toolchains, and grappling with technical debt, developers and SREs have had to make trade-offs between keeping the lights on and driving innovation. That’s why I’m excited to share a new offering built to take the pressure off: IBM Enterprise Application Service for Java (EASeJ).

What Is EASeJ?

EASeJ is a fully managed service that simplifies how enterprise teams build, deploy, and run Java applications in the cloud. It’s part of IBM’s new JSphere Suite for Java, which provides flexible modernization options for both fully cloud-managed and customer-managed environments.

With EASeJ, teams no longer have to manage runtime infrastructure, complex CI/CD pipelines, or custom modernization paths from scratch. Instead, it comes pre-packaged with the tools needed to modernize legacy apps and run cloud-native workloads at scale.

Why EASeJ Matters

Over 30% of engineering time is spent managing technical debt¹. And while cloud-native adoption is growing, many Java applications are still tied to legacy platforms that are difficult and expensive to move.

EASeJ helps teams offload the complexity of managing infrastructure, Kubernetes, compliance, and security—so they can bring code, and lets IBM handle the rest.

EASeJ addresses this with:

• Managed CI/CD pipelines for faster, more secure delivery
• 99.95% SLA across three cloud availability zones
• Application Modernization Accelerator (AMA) to rapidly assess app dependencies
• AI-assisted development via watsonx Code Assistant (wCA) (sold separately)

This service is ideal for organizations that want to reduce operational overhead, modernize at their own pace, and unlock more value from their Java investments, without needing to learn Kubernetes or OpenShift.
