Cloud Trial Managed Instances

Trial Managed Instances (aka PoC) are private, dedicated Sourcegraph instances provisioned and managed by Sourcegraph - more. The purpose is to provide free of charge Managed Instances for future customers for a trial period (default is 30 days).

All processes are the same as for paid Managed Instances (for paying customers):

Difference from paid instances

The difference from paid Managed Instances:

  1. During the trial period, Sourcegraph is covering all the infrastructure and licence costs.
  2. Trial Managed Instances have the GCP label instance-type=trial, which allows to filter them.
  3. Trial Managed Instances are monitored for trial expiration period (default 30 days). When a Trial Managed Instance expires, the instance requestor has to decide to:

Request Trial Managed Instance

The requesting Trial Managed Instance process is similar to paid one, except it’s raised by opening a trial managed instance request issue

Technical details

Monitoring Trial Managed Instances

Trial Managed Instance are automatically checked daily for expired trials. If Trial Managed Instance period exceeded 30 days, it will notify Cloud Team on Slack channel #cloud-notifications. Cloud Team will notify instance requestor and ask for choosing one of the options:

End of trial

After 30 days of trial, the Growth Team (DRI Malo Marrec) will be responsible for making sure one of the three following next step is triggered, after consultation with the account owner (if any):

  • extend trial managed instance
  • convert trial to paid customer
  • teardown the managed instance

Picking one of those three next steps is due with 5 days after the end of the 30 day trial period. In the future, this process will be automated.

Extend Trial Managed Instance

When trial expires and should be extended (by default 30 days), the instance requestor will create Managed Instance Trial Extend Github issue. Cloud Team will add trialAdditionalDays to customer config.yaml to ensure extended trial period is monitored.

Convert trial to paying customer

When customer has decided to sign the deal, instance requestor will create Managed Instance Convert Trial to Paid Github issue. Cloud Team will modify GCP label instance-type=production.

Teardown Trial Managed Instance

When trial expires and customer do not wish to sign the deal, instance requestor will open Teardown Managed Instance request
