The Trader Stock Desktop Demo

The following explains the Trader Stock Desktop Demo Flow
The Deployment will involve the following:

• GSM Machine - Running GSM and the Dynamic Provisioning Agent (DPA)
• Load-Balancer Machine
• GSC Machines - Running Web Application , IMDG and Services

  

1. Click the Stock Demo button - The system will start provisioning the web application on the cloud. This will include a machine for managing the cloud, a machine for HTTP 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 a "running" link on the load-balancer machine.

   

   Click on this link to open your web-client application.

   

   The client will update the stock prices. You will be able to select specific Stock to view.

2. Test Auto-Scaling - click multiple times on the "running" link to open more web clients. This will generate some load (request/sec) on the system. As soon as the request/sec will grow beyond a certain threshold you will see new machine being started. 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 rout new HTTP requests into the new web-container.

   

3. Test Self-Healing - Shutdown one of the machines by clicking the terminate button and see how your web client is behaving. You will see that even though the machine was terminated the client is hardly affected.

   

4. What's going on Behind the Scenes - 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. This will open-up the management console on the cloud. With this tool you can view all the components of the system. You can query the data using SQL browser and view the data as it enters into the system. In addition to that you can choose to add more services, relocate services through a mouse drag and drop.

   

5. Shutdown the Application - Once you are done, Click the Shutdown Button at the Cloud Console to terminate all the machines running the application on the cloud.
