a. Gateway Services need to be deployed independently using the subsystem definitions for the gateway leveraging the apicup installer, requiring specific editing of namespace and image registry. This can then be deployed ready for automated addition to the API Connect Cloud as above 

The guideline provided for automation shows that REST APIs are available on the API Connect Cloud in order to sufficiently automate the provisioning of API Provider teams. Individual use cases might vary and the assembly of the different REST APIs into a process need customization into some form of pipeline. 

## Rollback 

In the event of a rollback, there are two options available. The first option is to use backup configurations of the system to bring the system back to before the changes were made. However, this risks losing API, product, and membership data, which would be a heavy-handed approach. 

The second option is a fix forward strategy. This can be achieved by using the available REST APIs to GET all the relevant resources that might be touched by the automation or manual process. Given an event that requires a rollback, the system can be restored to its previous configuration (active Organizations and Catalogs). You can use either a manual process or further automation that resolves the configuration to a pre-change state. 

We can now provision new API Provider teams using both manual and automated steps in API Connect. 

## 8.5 High availability and scaling on containers for API Management 

As discussed in the introductory chapters, agile practices in integration are giving rise to new patterns of deployment. We need the API management infrastructure to be able to fully use the cloud-native infrastructure, both from a high availability point of view and also to enable scaling. In this section, we explore how deployment on containers enables API Connect to provide a more nuanced availability and scalability model. This uses the underlying standards-based Kubernetes platform to look after the infrastructure orchestration, simplifying installation and maintenance of the overall topology. 

## 8.5.1 High availability in a containerized environment 

API Connect leverages Kubernetes as a container orchestration platform and also the Quorum concept (described in “Quorum” on page 554) to provide a sophisticated high
