5 -In the previous microlearning, we discussed what needs to be done in the Create phase to enable failover for systems that are configured to have them in the Design phase. Next to that, we also discussed that setting up this failover functionality in your model requires you to execute some steps in your Design, Create, and lastly Deploy phase. Picking up from what we have toggled in the Create phase, in this microlearning, we will focus on the steps and configurations that you have to make in the Deploy phase to activate the active/passive failover functionality.
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.

15 -This microlearning describes what configuration that you will have to do in the Deploy phase, based on what you have configured in the Design and Create phase, to enable failover for systems connecting with your model. The grouping and failover 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"]].

17 +eMagiz needs to install a specific agent in the Docker instance that allows to download runtime images that need 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. In case the command is presented it means that this machine is not yet equipped with the eMagiz Deploy agent. The command can be executed inside the Linux command prompt on the on-premises server.
18 +
19 +Once the agent is installed, eMagiz can manage the machine to deploy new runtimes and or update runtimes as needed. Also the container runtime can be controlled with start, stop, et commands. Please consult this [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.eMagiz Runtime Management.intermediate-emagiz-runtime-management-interpret-on-premise-logging.WebHome||target="blank"]] to inspect the on-premises runtime logs.

21 -After finishing up your configuration in the Create phase, you can then move to your Deploy>Architecture. Here, you will see the new router containers, which we have seen in the Design>Architecture, to be added to your external machines. When you press "Start Editing" in this page, and then press "Apply to environment", you will be faced with a pop-up page that informs you that these router containers will be created for this specific environment as shown in the screenshot below.

25 -Once you have applied the changes, if you go to the "Details" of each of those machines via right-cliking them, then you can find and set, for each failover runtime, the preferred machine to be the leader. As an example shown in the screenshot below, there are two runtimes that are enabled for failover and you can select whether that runtime running in that "External 01" machine is the preferred leader or the backup, or if you want to reset it back to "None".

36 36  
37 -* Grouping is beneficial when external systems go through maintenance or downtime.
38 -* 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.
39 -* The role naming in both grouping and failover is crucial. The whole name needs to be matched fully to make it work.
40 -* For the infra configuration of the failover setup, we have a store item that you can use.
25 +* The eMagiz Docker agent needs to be installed to allow runtime to be installed on the on-premises server
