Managed services Content
The Content Runtime environments consist of three key components: a pattern manager, a Chef server, and a software repository. These runtime environments run in your location and space on a single virtual machine (VM). You can have more than one runtime environment to serve different purposes, such as development, test, and production. There must be bidirectional network access between these runtime environments and the Managed services environment.
These advanced Content Runtime environments must be set up before you can deploy a pattern or template. The setup process is a one time step which is performed through the Managed services user interface by using Terraform templates.
As part of the Managed services installation, there is a Terraform Provider container that must have network access to communicate with the VM and network in which the runtime environments operate. It must also be able to communicate with the managed VMs. This container can communicate with the Content Runtime environments over either the public network or a virtual private network (VPN). If communication takes place over a private network, which can be either Amazon or IBM Cloud, the container must also include VPN services. The following Figure 1 illustrates this Managed services Content overview.

For optimal performance, the runtime environments should be set up in a location that is geographically close to where you want to deploy your templates. After you configure a runtime environment, the settings are stored in a secure location in
Managed services that identifies the deployed
RUNTIME name and the associated settings, such as data center, IP address, and credentials. The settings are later injected as an input to a template during deployment when you select
RUNTIME name to use to deploy a template. All variables must be modeled in
camvariables of the template that is being deployed to ensure the expected behavior during deployment. When you deploy a template, you select
the target runtime environment and the system injects the associated values for that runtime environment into the pattern or template.
- Consider where (for example, the region, the data center, and the environment) you want to deploy templates as you plan the setup of your runtime environment.
- Be sure to have a well-defined plan of your desired topology, taking into account available network communication.
- Be sure that the outputs that are stored from the runtime environment align with the expected inputs for your templates. If these outputs and inputs are not aligned, you are prompted to define the runtime parameters for each deployment, which can be difficult and error prone.
Managed services Content frameworks
The Managed services Content Middleware Template Library was built around a set of non-proprietary frameworks which are openly available.
Terraform and Chef were chosen for standardizing the IBM-created content due to the following key advantages:
- Popularity and growth with users.
- A community Model for development, support, and third-party tools.
- They are proven for Enterprises at scale.
- Support for hybrid environments (environments that are based both in the cloud and on-premises).
- Consistent automation format and management for IBM content.
Both communities provide learning resources:
Note: Although the IBM Content is created using Terraform and Chef, Managed services does not preclude the use of other popular tools.
What to do next
The topics and tasks in this section guide you through configuring these runtime environments and deploying templates from the Middleware Template Content library. For more information, see Provisioning and managing the Content Runtime.
