The following section provides an overview of the Styra Self-Hosted DAS Installation Guide, Styra DAS, Styra DAS architecture, and the microservices used with Styra DAS.

Document Overview and Audience

The Self-Hosted Styra DAS Installation Guide contains information on configuring and installing Styra DAS on a wide selection of cloud infrastructure providers. The contents of the Infrastructure Configuration and the Cloud Agnostic Infrastructure sections are not, however, meant to be a comprehensive guide to cloud infrastructure. The infrastructure sections of this document are intended to provide guidance specific to configuring and instantiating infrastructure for use with Styra DAS. Accordingly, this document assumes the customer is familiar with managing their own infrastructure and defers to provider-specific documentation wherever possible.


Styra DAS can also run on self-managed or non-cloud infrastructure. Such setups, however, tend to require customized support and compatibility patterns. If you cannot utilize any of the providers described in this document, we recommend working with Styra’s Sales and Solutions Architecture teams to determine the best method of deploying Styra DAS on your infrastructure.
