Public - Resource Requirement Calculator

1	Usage					Size Constants
2	Find the appropriate calculator below, and fill in a row per the usage instructions. Be sure to use the correct units, converting if necessary. For example, if given Terabytes of Git data, multiply by the GB per TB constant in order to get the number of Gigabytes (GB) as required by the calculator. The color of the CPU cores and Memory cells represents the pain/cost of provisioning from easy to difficult/expensive, but it's pretty subjective based on the organization. When we support distributed jobs (we don't yet), these estimates will reflect the size and shape of the distributed pool of nodes.					Name	Number	Unit

4						TB per PB	1000	TB/PB

23	Confluence & Jira sizing
24	Put the number of pages or issues and the desired interval into a row to estimate CPU cores and memory required. Note that this integration is likely to be limited or rate limited by the server before resource saturation.
