Using a custom enterprise build platform means running your Bitrise builds on virtual machines (VM) dedicated and specifically configured to your needs. With a private cloud, you have complete control over how and when your builds run.

Bitrise offers two types of custom build platforms for enterprises:

The private build platform is an advanced set-up with plenty of configuration options. To learn more about the details, contact us!

Dedicated vs private build platform

Check out the most important differences between the dedicated and the private build platforms:

Available service Dedicated build platform Private build platform
Selecting the resources available to your virtual machines
Dedicated Customer Success Engineer, who is an expert in Mobile CI/CD.
Initial onboarding assistance for the first month with weekly calls.
Continued CI/CD best practices mentoring with monthly check-ins from Bitrise Account Managers and Customer Success Engineers.
Weekly Infrastructure maintenance that includes licenses for virtualization, orchestration, and data storage.
Private network with a dedicated firewall and IP addresses -
Management dashboard access (vSphere and Google Cloud Platform) -
Customize the pre-installed tools on the VMs -


The stack indicates the virtual machine version that we will use to run your build. On a custom build platform, you need to choose your stack or stacks in advance and as of now, you cannot change them afterwards. You can choose any of the stacks that are available on, and you can choose multiple types of stacks.

If you wish to order more than one type of stack, be aware that at least one virtual machine for each stack must keep running at all times - in idle mode, if there are no builds running. This means that you cannot use all your virtual machines to run builds on the same stack at the same time. Let’s look at an example of how this works in practice:

Our example Workspace has three virtual machines, with Xcode 11 and Xcode 10.2 stacks. When no builds are running, an Xcode 11 virtual machine and an Xcode 10.2 virtual machine is running in idle mode while the third virtual machine is off. If the Workspace, however, wants to run three builds on the Xcode 11 stack. They can only run two at the same time because the third virtual machine is in idle mode with the Xcode 10.2 stack.

Machine setup

For both the dedicated build platform and the private build platform, you can choose the hardware resources available for your VMs.

For Xcode and Visual Sutdio for Mac stacks

Our Xcode and Visual Studio for Mac stacks run on machines provided by MacStadium. You need to select the type of Mac Pro machines you need and the number of virtual machines that will run on them.

We offer two different types of Mac Pro machines:

Both versions support hyperthreading so the effective number of cores is 12 and 24, respectively.

The minimum order is two 6-core physical machines (12 effective cores), to ensure there is redundancy: a single hardware failure will

The next step is to decide the virtual machine configuration:

A virtual machine requires at least two cores (out of either 12 or 24, depending on the Mac type). RAM capacity reserved for the virtual machines must be less than the full capacity of your chosen Mac because of the limitations of virtualization. For example, on a machine with 32 GB RAM, 27 GB can be reserved for the virtual machines.

Available MacStadium configurations

The table shows the available resources for each VM, depending on the number of concurrencies.

Number of concurrencies Available resources for each VM (6 core Mac Pros @3.5GHz and 32GB RAM) Available resources for each VM (12 core Mac Pros @2.7GHz and 64GB RAM)
1 concurrency 12 vCPU, 27GB RAM 24 vCPU, 54GB RAM
2 concurrencies 6 vCPU, 13GB RAM 12 vCPU, 27GB RAM
3 concurrencies 4 vCPU, 9GB RAM 8 vCPU, 18GB RAM
4 concurrencies - 6 vCPU, 13GB RAM
6 concurrencies - 4 vCPU, 9GB RAM
12 concurrencies - -

For Android & Docker stacks

Our Linux-based virtual machines are provided by Google Cloud Platform. You can choose from two different types of machines for your VMs:

You can also decide the amount of storage you need for each VM: it can be either 100 GB or 200 GB.

Available Google Cloud Platform configurations

The table shows the available resources for each VM.

Storage for each VM Available resources (Intel Xeon E5 @2.6 GHz with 4 vCPUs) Available resources (Intel Xeon E5 @2.6 GHz with 8 vCPUs)
100GB SSD/VM 4 vCPUs, 15 GB RAM 8 vCPUs, 30 GB RAM
200GB SSD/VM 4 vCPUs, 15 GB RAM 8 vCPUs, 30 GB RAM


Private cloud pricing is subject to the required resources and configuration. Our sales team can provide further details. Contact us, should you have more questions.
