The topics in this subsection explain how to integrate your brokered service more closely with Ops Manager to create a managed service and service tile for VMware Tanzu.
The next level of integration is to get your service to be deployed on Ops Manager rather than externally, on the same IaaS that your particular Cloud Foundry instance is deployed on, and by the same orchestration tool, BOSH.
This is usually one of the more involved integrations, as you will have to change your packaging to allow your service components to be deployed by BOSH onto the Ops Manager infrastructure.
Offering your software as a managed service means that your Ops Manager customers will not have to learn different ways to deploy, manage, and monitor different components of their application platform.
As with the brokered service, the service has a service broker and a tile listed on VMware Tanzu Network. VMware Tanzu Network lists managed services as “for VMware Tanzu,” without “Service Broker” in the name.
To integrate your service at this level, you will have to learn about stemcells, BOSH releases, and manifests. You will also have to decide how your service maps to virtual machines and how persistent storage is managed.
For a Minimal Viable Product (MVP) version of a managed service, we typically recommend that you aim for a single, shared service instance, and don’t yet worry too much about High Availability of this instance. This integration level is mostly about getting the BOSH packaging, deployment, and monitoring working correctly.
Once you have a managed service, you may decide to prioritize either on-demand provisioning of service instances, or making your single shared service instance more highly available.
When properly configured, BOSH monitors and restarts any failing processes and virtual machines that are part of your service deployment. But to further increase availability, you will have to think about spreading your resources across multiple availability zones or even regions, and replicating your persistent storage across those as well.
For BOSH to manage your service, you need to create a BOSH release for it. BOSH Releases explains how to do this, and how to use your already-existing Docker image as a shortcut.
Once you have created a BOSH release for your managed service integration, you can work through Building Your First Tile to create your tile.
The Tile Generator tool automatically creates the lifecycle errands that can run after a Ops Manager tile is deployed or before it is removed. Operators control which errands run the next time they click Apply Changes to redeploy. See the Errands topic for how Ops Manager operators control when errands run, and how to set default errand run rules in the tile.
At any level of integration, VMware recommends and supports using Concourse for continuous integration during development.
