Deploying a Containerized Application to a Cluster

Even though microservices can be deployed and managed via different means, we recommend you deploy each microservice in a Docker container. In a virtualized environment provided by a container, the logic and I/O for each microservice instance are completely separated even if they reside on the same physical server. This container-based approach lets us scale our deployment with maximum flexibility. For example, we can deploy 10 containerized microservices on a physical service. When the workload is increased, we can add more containers to the same server or a different server, depending on the resource utilization of a physical server. The deployment and load-balancing of microservices are managed by orchestration tools such as Kubernetes. Moreover, if one of the deployed microservices encounters a catastrophic failure, the orchestration...
