GlassFish 3.0 on Amazon cloud
By Orgad Kimchi-Oracle on Mar 03, 2009
Here is how you can run the demo of GlassFish 3.0 on Amazon cloud.
Where should I start? The best way to get started is to run a demo applicaiton and see for yourself how this integration works. To make it even simpler we offer the demo on our new cloud offering. This will enable you to expereince how a full production ready environment which include full clustering, dynamic scaling, full high avliability and Session replication works in one click. To run the demo on the cloud follow the follwoing steps:
1. Download the GlassFish web scaling deployment file from here to your local machine.
2. Get the mycloud page and get your free access code – this will enable you to get access to the cloud.
3. Select the stock-demo-2.3.0-gf-sun.xml then hit the Deploy button (you first need to save the attached file in one your local machine) – The system will start provisioning the web application on the cloud. This will include a machine for managing the cloud, a machine for the load-balancer and machines for the web and data-grid containers. After approximately 3 minutes the application will be deployed completely. At this point you should see “running” link on the load-balancer machine. Click on this link to open your web-client application.
4. Test auto-scaling – click multiple times on the “running” link to open more clients. This will enable us to increase the load (request/sec) on the system. As soon as the request/sec will grow beyond a certain threshold you’ll see new machines being provisioned. After two minutes approximately the machine will be running and a new web-container will be auto-deployed into that machine. This new web-container will be linked automatically with the load-balancer and the load-balancer in return will spread the load to this new machine as well. This will reduce the load on each of the servers.
5. Test self-healing – you can now kill one of the machines and see how your web client is behaving. You should see that even though the machine was killed the client was hardly effected and system scaled itself down automatically.
Seeing what’s going on behind the scene:
All this may seam to be like a magic for you. If you want to access the machines and watch the web containers, the data-grid instances and the machines as well as the real time statistics you can click on the Manage button button. This will open-up a management console that is running on the cloud through the web. With this tool you can view all the components of our systems. You can even query the data using SQL browser and view the data as it enters the system. In addition to that you can choose to add more services, relocate services through a simple click of a mouse or drag and drop action.
