You should be able to set up alerting mechanisms to detect and respond to issues proactively and recover from failures by restarting failed containers or reallocating workloads to healthy nodes.
- Working closely with development and engineering teams to establish CI/CD pipelines for automating the deployment and rollout of Kubernetes services. Support seamless rolling updates allowing new versions to be deployed gradually while maintaining application availability.
- Identifying performance bottlenecks in containerized environments and optimizing resource utilization through capacity planning, auto-scaling, and performance tuning.
