For AppStudio Beta

Also known as "Singapore Gateway Service"

Slack:  #forum-acm-singapore-gateway-service

Problem statement: 

Bringing a cluster into the AppStudio experience today that is not part of the DevSandbox.  AppStudio could build a registration flow, but they would rather consume one. This means providing cluster details to AppStudio, either from BYO self-managed or from Service Delivery.

Timelines:

• Internal Preview with AppStudio Dev Team - Mid-April (TBD)
• External closed Beta alongside AppStudio - June (TBD) (40-50 users)

Beta Requirements:

• AppStudio users are provisioned a single workspace and are the single user in that workspace. Clusters are scoped to the workspace. Post beta, with KCP, there will be a hierarchy of workspaces where you have an organization-level workspace containing many team workspaces. At that point, the cluster may be scoped to the organization so you only have to import it once and can use across workspaces. TBD later (post-beta).
• Per discussion March 18 with Jessica Forrester we can assume all clusters in the beta will be OCM clusters available on public Internet. We do NOT need to support private network/reverse proxy in this timeframe.
• The list of clusters the user can select from for their Environments will be populated from our registration service. There is no concept of trying to use an OCM cluster that has NOT been registered with our service in an environment.

Architecture

Singapore Gateway Service

The Singapore Gateway Service will initially be built as an integrated component of AppStudio (operator running on AppStudio member clusters) backed by one (or many) large MCE(s) provided via OCM. 

ManagedClusters reside on a single large MCE, or one MCE per AppStudio member cluster, or potentially (but unlikely we’ll grow this big before KCP) multiple MCE clusters (could be per AppStudio member cluster or shared across the member clusters).

Note: This may not be the same architecture used in the KCP-based AppCloud implementation
