Managed instances: cost estimation

How to calculate the cost of a managed instance

⚠️ IMPORTANT: This provides a rough estimate to the best of our ability, infrastructure pricing estimates are not trivial to do accurately and actual costs are always subject to change. The goal of this is to give you a rough estimate of costs, not an exact amount.

ℹ️ If unsure about anything with pricing for a managed instance, message @devops-support in the #cloud-devops – ensure you include all the information needed for the resource calculator and any extra information about why you need help.

Several data points are needed to work out the cost:

• Size of all of their repositories on disk
• Number of repositories
• Number of those repositories that are monorepos

These data points are also listed in the CS managed instance request template.

Thus, the smallest managed instance supporting around ~300 repositories and ~100 users costs around $726/mo. Add enough buffer to the pricing to account for some variation in usage—for example, an estimate of $10–15k for this instance.

Potential cost savings

The above does not take into account:

• Potential committed use discounts, which are handled transparently on Sourcegraphs’ side through cross-project committed use discount sharing and passed onto you automatically.
• Cost reduction based on proactive monitoring of services based on your actual usage—resource requirements of Sourcegraph vary widely depending on how your usage looks. This is handled automatically by Sourcegraph as part of monthly upgrades.

Detailed breakdown

The following describes how the above table was derived—reviewing this is not necessary for calculating the cost of a new managed instance.

The following summarizes the infrastructure costs incurred for a managed instance. Managed instances are always created in completely isolated GCP projects, and as such it is easy to see the exact infrastructure cost breakdown for a given customer.
