Deis must support 100% automated, zero-downtime updates of the control plane.

Like CoreOS, Deis clusters should be attached to an alpha, beta or stable channel and rely on an automatic update mechanism.

To accomplish this, Deis plans to use the `Google Omaha Protocol`_ as implemented by `CoreUpdate`_.
15+
Pluggable Storage Subsystem
16+
---------------------------
17+
Deis uses Ceph to provide a highly-available storage subsystem for stateful control plane components.
18+
While Ceph is the right default storage subsystem, it is tricky to operate and can result in control plane instability.
19+
Ceph should be optional, especially for users on AWS with direct access to services like S3.

Etcd 2
78+
------
79+
A CP database like etcd is central to Deis, which requires a distributed lock service and key/value store.
80+
As problems with etcd directly impact platform stability, Deis must move to the more stable etcd2.

User-defined Health Checks
88+
--------------------------
89+
Today Deis relies on TCP port checks as evidence of container readiness during deploys.
90+
To facilitate a better zero-downtime deploy experience, Deis should allow user-defined
91+
health checks that are respected during the rolling deploy process and to verify that containers
92+
are healthy before publishing them to the routing mesh.
