### Quality of Service for memory resources

  * ELB:
    * ELB proxy protocol support 
	* mixed plaintext/encrypted ports support in ELBs
    * SSL support for ELB listeners
  * Allow VPC CIDR to be specified (experimental)
  * Fix problems with >2 security groups
* GCP:
  * Enable using gcr.io as a Docker registry mirror.
  * Make bigger master root disks in GCE for large clusters.
  * Change default clusterCIDRs from /16 to /14 allowing 1000 Node clusters by default.

## FastAPI App with Tags

In many cases your FastAPI app will be bigger, and you will probably use tags to separate different groups of *path operations*.

For example, you could have a section for **items** and another section for **users**, and they could be separated by tags:
