CloudBees Core on traditional platforms reference architecture

Estimating your requirements for CloudBees Core on traditional platforms

You can estimate your organization’s Client Master and executor [1] requirements, based on the number of developers in your organization. These requirements should provide a good basis for your initial CloudBees Core on traditional platforms installation.

  1. Estimate the total number of Client Master items (i.e. Pipeline projects, jobs and other items configured on a Client Master) in your CloudBees Core on traditional platforms installation. This can be based on the approximation:

    • No. of (Client Master) items = no. of developers * 3.333

  2. Using this "no. of items" value, estimate the number of Client Master instances required for your CloudBees Core on traditional platforms installation. Typically, each CPU core of the hardware on which the Client Master is installed can support a maximum of 100 Client Master items. If, for example, your Client Master’s hardware has 5 CPU cores, then the Client Master can support a total of 500 items. Assuming this hardware arrangement for each Client Master:

    • No. of Client Masters required = no. of items / 500

  3. Last, you can estimate the number of executors based on this simple formula/approximation:

    • No. of executors = no. of items * 0.03

Your estimated required number of Client Masters (step 2 above) can help you plan how many Client Masters you should install for your initial CloudBees Core on traditional platforms installation. If your estimate is two or more Client Masters, then consider installing a Operations Center to manage these Client Masters.

1. An executor is a slot of execution of build work defined by a Pipeline project/job, typically performed on an agent.
