+# 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 BigBang?
+
+BigBang itself is open-source, and you do not need to pay Platform One
+to use it in your environment.
+
+Out 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 here:
+[BigBang Licensing Model Overview](./understanding-bigbang/licensing-model/)
+
+In BigBang 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 AO may require certain commercial applications for a cATO.
+
+> Are users required to set up a "contract" with Platform One in order to
+use BigBang?
+
+No. BigBang 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 Integration Team helps customers install and operate BigBang on customer
+  hardware and in customer environments.
+- [Party Bus](https://p1.dso.mil/products/party-bus) is a managed environment and
+  instance of BigBang, which an application can be hosted on. PartyBus removes the
+  need for you to operate a cluster entirely.
+- Finally, 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

+
+> 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.

+
+## Security
+
+> Is BigBang secure? What about its plugins?
+
+BigBang is compliant with the
+[DevSecOps Reference Architecture](https://dodcio.defense.gov/Portals/0/Documents/Library/DoD%20Enterprise%20DevSecOps%20Reference%20Design%20-%20CNCF%20Kubernetes%20w-DD1910_cleared_20211022.pdf),
+and is used at all Impact Levels and Classifications. Each IL and classification is
+deployed to a separate environment and separate cluster, which keeps them separated.
+
+[IronBank](https://p1.dso.mil/products/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 IronBank.
+

+
+## Deployment
+
+> Can we stand up our own instance of BigBang in AWS GovCloud?
+
+Yes. BigBang 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 BigBang
+> to a VM?
+
+BigBang is, at its core, a Helm chart, which creates templates for Kubernetes
+resources. As such, BigBang requires a full K8S environment.
+
+If your organization is unable to support a full K8S environment, you may wish to
+consider [Party Bus](https://p1.dso.mil/products/party-bus), which is BigBang's
+managed Platform as a Service (PaaS) solution.
+
+## Change Control
+
+> How do you manage change control on BB? How can we be notified of changed?
+
+BigBang has a two-week release cadence. You can view our
+[release schedule](https://docs-bigbang.dso.mil/latest/#Navigating-our-documentation),
+our [project milestones](https://repo1.dso.mil/groups/big-bang/-/milestones),
+and our [release notes](../release-notes/)
+for more information.
+
+

+
+> Can you provide the latest documentation and briefings?
