* Kubernetes Cluster auto scaler will scale in and scale out the Nodes based on CPU and Memory Load.

* Nodes are Virtual/Physical machines.
* Each Microservice (Multiple services combined as container) is deployed as POD. Each POD is deployed into multiple Nodes for resilience.
* PODs are enables with autoscaling based on CPU and Memory Parameters.
* All Pods are configured to have two instances, each deployed in different Nodes, using the node affinity parameter.
* PODs are configured with self-healing, which mean when there is a failure a new POD is spun up.
