Red Hat Summit7.3. Locations and Topology
This section outlines general considerations that should help you to specify your Satellite deployment scenario. The most common deployment scenarios are listed in 8章Common Deployment Scenarios. The defining questions are:
- How many Capsule Servers do I need? – The number of geographic locations where your organization operates should translate to the number of Capsule Servers. By assigning a Capsule to each location, you decrease the load on Satellite Server, increase redundancy, and reduce bandwidth usage. Satellite Server itself can act as a Capsule (it contains an integrated Capsule by default). This can be used in single location deployments and to provision the base system’s of Capsule Servers. Using the integrated Capsule to communicate with hosts in remote locations is not recommended as it can lead to suboptimal network utilization.
- What services will be provided by Capsule Servers? – After establishing the number of Capsules, decide what services will be enabled on each Capsule. Even though the whole stack of content and configuration management capabilities is available, some infrastructure services (DNS, DHCP, TFTP) can be outside of a Satellite administrator’s control. In such case, Capsules have to integrate with those external services (see 「Capsule with External Services」).
- Is my Satellite Server required to be disconnected from the Internet? – Disconnected Satellite is a common deployment scenario (see 「Disconnected Satellite」). If you require frequent updates of Red Hat content on a disconnected Satellite, plan an additional Satellite instance for inter-Satellite synchronization.
- What compute resources do I need for my hosts? – Apart from provisioning bare metal hosts, you can use various compute resources supported by Satellite. To learn about provisioning on different compute resources see the Provisioning Guide.
