4 -eMagiz flows, or more specifically, the flow's inbound component(s), can be grouped. How to configure this is explained [[here>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.Grouping and Failover.intermediate-grouping-and-failover-flow-configuration.WebHome||target="blank"]]. This functionality is mainly beneficial when faced with substantial maintenance or outage of systems connected to your eMagiz model.

6 -Building on this functionality, you can even configure the group to run in an active/passive failover mode when you activate the multiple runtimes option on your runtime, and each separate runtime is deployed on another machine. The failover functionality is not only relevant in cases of server maintenance. It can also assist you when you want to exchange data with a system that allows only one active connection. Should this connection be business-critical, you can use this failover functionality to create a passive failover situation that will take over when the active connection breaks down (regardless of the reason).
3 +eMagiz runtimes can run on local, on-premises servers. Main reason is that some systems are only accessible from within the client's infrastructure. In such scenario's that on-premises server needs to be equipped with a linux based Docker installation.

18 -This microlearning describes how to configure (parts of) your deployment plan to set up the grouping and, if needed, the failover functionality. The grouping functionality is relevant when faced with maintenance and outages of systems connected to your model. The failover functionality assists in that case and allows you to have a fallback option on an active connection.
13 +This microlearning describes how the eMagiz Deploy agent is installed on the on-premises server where a eMagiz runtime should run on. Please note that the eMagiz Deploy agent requires a valid Docker installation on the on-premises server. The detailed install guide can be found in this [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Expert Level.Solution Architecture.expert-solution-architecture-onpremises-server-installguide.WebHome||target="blank"]].

20 -== 3. Group Deployment Step ==
21 21  
22 -To configure a Group deployment step, you need to add a new deployment step and choose Step type "Group". To configure the step more information is required. A container should be chosen for which the inbounds will be stopped. The second requirement is the **exact** name of the group that should be affected by the deployment step. An action should be picked for the selected group. For a "Group" deployment step the options are to start or to stop the inbound components within the groupname. Optionally, a description can be added.

18 +eMagiz needs to install a specific agent in the Docker instance that allows to download runtime images that needs to be installed on the Docker instance. The specific command to run inside the Docker instance is specific for the machine that is configured inside eMagiz Design & Deploy Architectures. It can be found inside the eMagiz iPaaS portal under Deploy Architecture. At the runtime connector, there is a right click option called Deploy Agent. That presents either the command or the location where that agent is installed.

28 -If you want to expand the grouping functionality to include an active/passive failover component, you need to change the settings on the inbound component. Apart from specifying the group name, you need to configure the auto-startup option on "No" so the failover configuration can take the correct actions in all situations.
22 +After installing the agent, you can use the Docker cheat sheet below to see if the docker containers are running and/or images are available.

38 -The configuration of the infra flow of the runtime for which you want to configure the failover is detailed and only works if you configure all support objects correctly. Although we explain the various steps in the documentation, we advise utilizing the store item we created for this that will guide you in setting this up correctly.
39 39  
40 -The configuration consists of at least three separate support objects. Two are needed once (infinispan cache manager and clustered lock registry), whereas the other is required per unique group you have defined within the context of your runtime. So, if you have two unique group names within the runtime, you need two leader initiator support objects.
41 -
42 -=== 3.3.1 Infinispan Cache Manager ===
43 -
44 -Given this, let us first look at the Infinispan cache manager. You can add this support object in the [[standard manner>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-create-support-objects-introduction||target="blank"]] by searching for "infinispan cache manager."

58 -Now that we have the cache manager, we can configure the next support object on our list, the clustered lock registry.

68 -Lastly, we need to configure a leader initiator for each **unique** group we have defined within the context of the runtime, and that uses the failover functionality.

76 -== 5. Key takeaways ==
77 -
78 -* Grouping is beneficial when external systems go through maintenance or downtime.
79 -* Failover can have the additional benefit of having a fallback scenario while still adhering to the requirement that there can only be one active connection at a time
80 -* The role naming in both grouping and failover is crucial. The whole name needs to be matched fully to make it work.
81 -* For the infra configuration of the failover setup, we have a store item that you can use.
