3. Implement state-of-the-art application instrumentation (logging, tracing, metrics).
4. Manage name server registry, auto DNS, service discoverability, service registry, and service management.
5. Work with SpringBoot platform, SpringBoot server, and SpringBoot Admin.
6. Utilize Ansible/Terraform and Kubernetes for deployment and orchestration.
