Hi Dan,

You currently have a single-node architecture on your server where in the same server you have an OutSystems Front-End, OutSystems Deployment Controller and SQL Server Database running. What you have to do to add a new OutSystems Front-End node to your OutSystems Farm is simply install the OutSystems Agile Platform in your new server and configure it to work as an OutSystems Front-End. When configured, this Front-End will automatically register itself in the OutSystems Deployment Controller and access the existing SQL Server Database.

From a high level, what you have to do to add new node in your OutSystems farm is the following:

1. Provision a new server node in Amazon;
2. Install the OutSystems Agile Platform in this new node (the same version same version and revision - eg. 5.0.2.14 - that you have installed in the existing server);
3. Configure this new OutSystems node so that it "registers" itself in the OutSystems farm as a Front-End server:
4. • Do not worry about the database, this OutSystems node can access the database even if it is installed in the previously existing Front-End;
   • This step will automatically deploy all OutSystems applications to this new node - after this step, the server is able to process OutSystems requests;
5. Configure the Amazon load balancer in order to also direct requests to the new node.

To get the detailed information on steps 2 and 4, you can read the Platform Server 5.0 - .NET Install Checklist document and configure the document as shown in the picture below.



Finally, i would just like to tell you that we are missing details in the step "In Configuration Tool, import the configuration file" of the OutSystems Platform Server Installation Check list section (we are already improving our check-list on this detailed). In this step, what you have to do is the following:

1. Backup the configuration file by going to the existing OutSystems Controller server node, opening the OutSystems Configuration Tool and choosing File > Save;
2. In the new Front-End server, import the configuration file by opening the OutSystems Configuration Tool and choosing File > Import. After that, exit the Configuration Tool by clicking OK.

Hi Dan,

I would like to tell you that I have just published the HOWTO configure load balancing in the Amazon Cloud.

@Daniel Are there any specific software/Outsystems license requirements needed to setup load balancing? (it does not say)

You are right, Robert. In order to have more that one OutSystems Front-End, you have to have the OutSystems Professional Edition or above.

You can see all the details at https://www.outsystems.com/agile-platform-editions .
