In today's world, the need for highly available and fault-tolerant systems is more important than ever. Furthermore, with the increased adoption of microservices and containerization, the need for a reliable infrastructure that can automatically detect and recover from failures has become critical. Kubernetes, an open-source container orchestration platform, and Prometheus, a popular monitoring and alerting toolkit, are two tools that can be used to implement such a self-healing infrastructure.
Kubernetes provides a highly scalable and flexible platform for managing containerized applications. It includes features such as automatic scaling, rolling updates, and self-healing, making it an ideal choice for building highly available systems. Kubernetes provides two types of self-healing mechanisms: liveness probes and readiness probes.
