Talend Deployment Modes(Kar Vs Artifact Repository)

I am trying to understand different deployment modes in Talend

1. Direct deployment of Data Service / Route in Runtime
2. Publishing the Route/Service to Artifact repository. then create a task in ESB conductor and deploy it to the runtime server.

In Mode 1, talend installs deploys the .kar file into its data directory and enables the service.
I'm not sure about mode 2.

Can anyone help me to understand , what happens internally in the mode 2 ?
What is the deploy option in ESB conductor doing at the the backend ,how the service is getting installed as service in talend runtime?

Re: Talend Deployment Modes(Kar Vs Artifact Repository)


what you describe as mode 1 and mode 2 are essentially our two deployment options (+ one more for Restful Data-Services and Routes where we also support a Microservice (Spring Boot) based deployment)


Mode 1 (via KAR-File): is suitable if you have access to the deployment folder or if you like to deploy the routes / features in an automated way by file copy to the deploy folder. This is an easy way to deploy Routes/Service to the runtime but it uses the auto install from Runtime via the deploy folder and by this e.g. no easy way to change the context properties during deployment and you need file access to the deployment folder. It is by still a possible production deployment option but in most cases more used during testing.


Mode 2 (via Artifact Repo) is more the standard deployment option for Routes and Services but only available in the Subscription products as it depends also on TAC ESB Conductor. By this an ESB Route/Service can be published to the Artifact Repo (Nexus) and then you create a Deployment Task in the TAC ESB Conductor to install it to the Runtime. Technically we only send JMX commands to the Runtime and the Runtime will download and install the feature directly from the Artifact Repo (means the Runtime needs also access to the Aritfact-Repository). With this option you can use the TAC ESB Conductor screen to deploy / undeploy a feature to one or many Runtimes (either by individual tasks or using the Virtual Server concept in TAC).
Beside the user interface for remote deployment (ESB Conductor) you have also a more easy way to select the context (e.g. PROD, QA, DEV) and to overwrite individual context parameter at deployment time. This is the biggest difference between the two options. The running Route/Service is essentially the same independent of your decision to go with Mode 1 or Mode 2.
