You can also install Kiuwan On-Premises under your own AWS cloud, replacing the provided infrastructure services with compatible AWS services.
Kiuwan On-Premises defines three different roles for each instance:
The default installation will create a Kiuwan instance of each role.
All needed services re supplied as Docker containers. The following table summarizes all the available services:
The following diagram shows how Kiuwan On-Premises would be set out by default (that is, a single host default installation):
The main purpose of each piece is (service names are shown between parentheses):
Note that connection with Kiuwan Cloud is only needed in some situations (see Needed internet connections).
Depending on your needs, the Kiuwan On-Premises architecture supports both clustered environments and single-host installations. You can:
All Kiuwan instance containers can be scaled up (to a limit) or down to the default configuration. This means that you can start more containers of each Kiuwan role depending on your load needs.
To illustrate the flexibility that Kiuwan On-Premises installation tool provides, an alternative and possible configuration is depicted in the following image (Kiuwan Cloud and temporal services were ommitted in order to simplify the diagram):
As the picture shows, you can distribute Kiuwan On-Premises services across different hosts and use external services to replace some of the ones provided.
