# Mcrouter
Mcrouter is a memcached protocol router for scaling Memcached deployments. It
is a core component of cache infrastructure at Facebook and Instagram where
Mcrouter handles almost 5 billion requests per second at peak.
OpenStack usually comes down to a halt if one of the Memcached instances don't
respond anymore. Mcrouter is used to enable high availability and redundancy
so that any Memcached outages will not affect the OpenStack services.
The only two possible reasons that we can have a full system slowdown at the
moment remains:
- All backends (Memcached instances) are all down
- All Mcrouter replicas are down
The first probably means there's a bigger issue in play, the latter will
likely automatically recover by Kubernetes ensuring that replicas come back
up. Also, due to the fact that the service is exposed as a ClusterIP, it only
takes a single replica to be up for everything to come back to start working
again.
## Example
```yaml
apiVersion: infrastructure.vexxhost.cloud/v1alpha1
kind: Mcrouter
metadata:
name: sample
spec:
route: PoolRoute|default
pools:
default:
servers: ['10.0.0.1:11211', '10.0.0.2:11211']
```

# Memcached
Memcached is an in-memory key-value store for small chunks of arbitrary
data (strings, objects) from results of database calls, API calls, or page
rendering.
It's used in OpenStack for a lot of token caching and in other services such
as Nova to minimize load against the database cluster. This operator allows
you to deploy it and it automatically exposes a single IP address which will
point towards any of the two Mcrouter instances which are pushing data out to
the Memcached instances.
It will also automatically take the total number of megabytes and split it
across two shards (so setting `megabytes` to `128`) will result in two instances
each with 64 megabytes which are load balanced via Mcrouter.
## Example
```yaml
apiVersion: infrastructure.vexxhost.cloud/v1alpha1
kind: Memcached
metadata:
name: sample
spec:
megabytes: 128
```
