Frequently Asked Questions📜

Costs and licensing Fees📜

Will a user, government program, or support contract incur any costs, other than their own labor, for installing and using Big Bang?

Big Bang itself is open-source, and you do not need to pay Platform One to use it in your environment.

Our baseline includes multiple software components, with a variety of open-source and commercial licenses. Details of these components and their licensing models can be found in Big Bang Licensing Model Overview.

In Big Bang 2.0, our default core components will be open source, though paid alternatives will remain available.

You are in complete control over which components you install in your environment, and choose whether or not to use commercial software. However, your Approving Official may require certain commercial applications for a cATO.

Are users required to set up a “contract” with Platform One in order to use Big Bang?

No. Big Bang is open source, and can be used by you and your organization without payment to Platform One.

Platform One does offer optional hosting and support contracts:

  • Our Big Bang Integration Team helps customers install, upgrade, and operate BigBang on customer hardware and in customer environments.
  • Our Digital Twin service will deploy an instance of your application to our testing clusters, so we can ensure that changes to our baseline won’t break your integration tests. Providing you with customized release notes for your environment.
  • Party Bus is a managed environment and instance of Big Bang, which an application can be hosted on. Party Bus removes the need for you to operate a cluster entirely.

Do we need a government PM to send a formal request to Platform One in order to get started?

No. Big Bang is Open Source, and you do not need our permission to use it. However, we always like to hear from our users, both to know how large an impact this effort is making, and to make sure we are addressing our users’ most pressing needs.


Is Big Bang secure? What about its plugins?

Big Bang is compliant with the DevSecOps Reference Architecture, and is used at all impact levels and classifications.

Iron Bank performs automated scans of all image components used in Big Bang, and patches vulnerabilities as they are found. Big Bang pulls all hardened images from Iron Bank.


Can we stand up our own instance of Big Bang in AWS GovCloud?

Yes. Big Bang strives to be vendor-agnostic, and will run on Cloud One, AWS GovCloud, Microsoft Azure, on-prem hardware, and in air-gapped environments.

Do we have to set up a full Kubernetes distribution? Can we just deploy Big Bang to a Virtural Machine?

Big Bang is, at its core, a Helm chart, which creates templates for Kubernetes resources. As such, Big Bang requires a full Kubernetes environment.

If your organization is unable to support a full Kubernetes environment, you may wish to consider Party Bus, which is Platform One’s managed Big Bang Platform as a Service (PaaS) solution, or one of the Big Bang Resellers.

Change Control📜

How do you manage change control on Big Bang? How can we be notified of changed?
