Scout Tutorial
This page belongs to the Cloud Tutorial.


Deploy your Scout App to the Cloud

We analyzed several PaaS vendors and made a list of vendors which are able to run the eclipse scout server application. See section "Suitable PaaS Providers" in this blog post for a brief overview.

As Amazon is a big player in the cloud environment and one of the few vendors who offer running multiple server nodes for free, this tutorial is based on the Amazon AWS Elastic Beanstalk offering to describe the installation and deployment of a Scout application to a PaaS environment.

If your don't have an Amazon AWS Acount just sign up here.

Preparation

Before you can upload your Scout application, you have to configure the necessary database, cache and message queue services.

For the configuration of those services login to your Amazon [Console].

Memcached

  1. Under the category Database open the point "ElastiCache - In-Memory Cache".
  2. Select "Launch Cache Cluster"
  3. Fill the Cluster Details like in the Graphic below.

  5. Finally you get an overview over your cluster configuration. If everything is fine click "Launch Cache Cluster"


RabbitMQ

Amazon provides with AWS SNS & AWS SQS a Pub/Sub Messaging-System but its not easy to build a dynamic environment with this solution. Its easier to use to offer of cloudamqp.com. They are providing the RabbitMQ Message Queue as a Service, hosted in the Amazon Cloud. So create an Account at cloudamqp.com for later use.


MySQL (optionally)

If you later want to use a database follow this steps, if not continue with "Create Beanstalk Application"

  1. Under the category Database open the point "RDS - Managed Relational Database Service".
  2. Create a new Database Instance by clicking "Launch a DB Instance".

If you want to connect from your local system to the DB, you have to add your ISP IP-Adress to the Security Group of the Database
