▪ Why we need to orchestrate our containers ?

▪ Think to developed and containerize our microservices and ready for shipping

and deployment. Why we need an orchestrator for our containers ?

▪ Deployment requirements of microservices, think that have hundreds of

microservices, we should ask;

▪ How container instances be provisioned into cluster of multiple machines ?

▪ After deployment, how will containers discover and communicate with each other ?

▪ How can containers scale in or out on-demand and peek traffic ?

▪ How do you monitor the health of each container ?

▪ How do you protect containers against hardware and software failures ?

▪ How do upgrade containers for a live application with zero downtime ?

▪ All these questions handled by Container Orchestrators that automate all

these concerns.

▪ These task can not be managed by manually administrated for thousands of

independently deployed containers.

▪ Containerized services require automated management.
