Kiuwan On-Premises can be installed on a single host or on multiple hosts (externalizing one, some or all of the provided infrastructure services).
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.
Note that although distributed architecture is feasible, we do not provide explicit documentation on how an installation of this kind has to be performed, as there are plenty of manual steps and usually the single-host approach is valid for most customers. in case your company needs more advanced architectural solutions for a Kiuwan On-Premises Distributed installation, please contact Kiuwan support.
