We are looking for a highly skilled Middleware Application SME to support the migration of containerized middleware workloads from on-premises Kubernetes clusters to Azure Kubernetes Service (AKS). The SME will assess, re-platform, and optimize middleware services such as ActiveMQ, RabbitMQ, Apache Tomcat, JBoss, NGINX, Apache HTTP Server, Kafka, Redis, and similar technologies, ensuring seamless integration into the AKS platform.
Key Responsibilities:
· Lead the discovery, analysis, and assessment of existing middleware container workloads for cloud readiness and prepare an Application Container services migration strategy on AKS.
· Review and optimize Kubernetes Container application manifests, Helm charts, Dockerfiles, persistent volume claims, config maps, secrets, and custom resources.
· Evaluate and remediate Application middleware services compatibility issues for AKS, including storage class transitions and ingress configurations.
· Define Application PODs/Container migration patterns/Wave planning, secret and credential management strategies, and integration with Azure Key Vault and Azure Container Registry.
· Collaborate with Application Architects, infrastructure and cloud architects to implement HA/DR strategies for middleware services on AKS.
· Define CI/CD integration strategies using Azure DevOps for middleware workload deployment, testing, and version management.
· Enable observability by integrating Azure-native monitoring, logging, and alerting services for containerized middleware.
· Provide technical leadership during migration execution, troubleshooting, and UAT support for middleware services.
· Document architectural decisions, migration procedures, and operational guidelines for middleware components on AKS.
