|Development||various||Development||on save||Fixture||individual dev|
Development happens on a local machine. Therefore there is no way to provide any SLA. Access is to the individual dev. This could be either EE/CE depending on what the developer is working on.
This should be a fully featured version of the current EE release. The high SLA and tightened access is to ensure it is always available for sales. There are no features (feature flags/canary/etc) that we do not ship.
|Dev||dev.gitlab.org||Tools for Gitlab.com||Nightly||Real Work||Production and build team|
Currently there are two main uses for dev, Builds and repos that are needed in case gitlab.com is offline. This is a critical piece of infrastructure that is always growing in size due to build artifacts. There are discussions to make a new build server where nightly CE/EE builds can be deployed or to move the infra repos to a new host that would be an separate (not gitlab.com) EE instance.
|Review apps||various||Test proposal||on commit||Fixture||Review app owner|
ephemeral app environments that are created dynamically every time you push a new branch up to GitLab, and they're automatically deleted when the branch is deleted. Single container with limited access.
|one-off||various||Testing specific features in a large environment||Release + patches||User specific||Team developing feature|
This is less of a staging environment more like a large scale development environments. This could be because of the number of repos required, or a full sized db is required. A version of CE/EE is installed and then patches are applied as work progresses. These should be very limited in number.
|Staging||staging.gitlab.com||To test master||Nightly||Pseudonymization of prod||all engineers|
This is the version we have today. A full environment that is managed by Chef and Terraform(single environment). This setup can at most be updated nightly* because it requires an omnibus version to install. This would be a static environment with a pseudonymization production database. the DB is a snapshot of the pre-prod DB (updated only often enough to keep migration times to a minimum).
* or however often we can have an omnibus build created.
K8s & helm charts (cloud native)
The final version of staging is multiple container deploys managed by K8s via helm charts. This could be mapped to Master and re-deployed every time there is a successful merge to master. There is already work started to move us to containers. https://gitlab.com/gitlab-org/omnibus-gitlab/issues/2420
|preprod||pre.gitlab.com||Simulate prod||Relase Canidate||Weekly copy of Production||Produciton team|
The pre-prod environment will be a mirror of the production environment topology, a full production DB and access restrictions. We will utilize end to end tests , via gitlab-qa, to ensure the quality of the deploy. In the future I would like to be able to mirror production traffic into pre-prod. This would make all of pre-prod in effect a canary deploy, except that if it breaks under load, real users are not affected.
|Production||www.gitlab.com||Production||Release Canidate||Production||Production team|
Production will be full scale and size with the ability to have a canary deploy. Production has limited access.
|Self-Hosted||various||Self hosted versions of CE & EE||User specific||User specific||User specific|
These are environments that are run on-premise by the end-user. We have no influence, access or control of these environments.
