Lead Middleware Migration Activities: Support the migration of Java-based enterprise applications from one data center to another, ensuring application servers, configurations, dependencies, and runtime environments are properly transitioned.
Install and Configure Application Servers: Install, configure, administer, and support IBM WebSphere Application Server and JBoss environments, including application deployments, JVM settings, clusters, nodes, profiles, data sources, security settings, and
related middleware components.
Support Java Application Platforms: Work closely with application teams to understand Java application architecture, runtime requirements, dependencies, and integration points to ensure successful migration and post-migration stability.
Perform Current-State Assessment: Analyze existing application and middleware architecture, document source environment configurations, and identify requirements for replatforming applications into the target OpenStack-based environment.
Migrate Middleware Configurations: Translate and migrate configurations from current source environments to target environments, ensuring consistency across application server settings, connection pools, JVM parameters, certificates, security configurations,
and environment-specific variables.
Tune Performance and Stability: Perform application server performance tuning, JVM tuning, monitoring, troubleshooting, and capacity-related analysis to ensure applications run reliably before, during, and after migration.
Validate Application Availability: Conduct smoke testing, health checks, log reviews, and post-cutover validation to confirm that applications are up and running successfully in the target environment.
Coordinate Across Teams: Collaborate with multiple application, infrastructure, database, security, network, and project teams to plan migrations, resolve issues, and communicate technical status clearly.
Support Production Cutovers: Provide hands-on support during production migration windows, including after-hours and weekend work as required for application cutovers, validation, troubleshooting, and rollback support.
Troubleshoot Complex Issues: Act as an escalation point for middleware-related incidents, including deployment failures, application startup issues, connectivity problems, JVM errors, performance degradation, and configuration mismatches. Onsite CA <
