GigaSpaces Scalability Live Demo

  1. 1. GigaSpaces Scalability Live Demo
  2. 2. In this Demo <ul><li>Experience automatic scaling based on request throughput </li></ul><ul><li>See how the application fails over and auto-recovers after failure </li></ul>
  3. 3. How to Experience Automatic Scaling <ul><li>Deploy the demo on the cloud </li></ul><ul><li>Study the demo architecture </li></ul><ul><li>Web auto-scaling (requests/sec threshold) </li></ul><ul><li>Automatic failover and auto-recovery </li></ul>
  4. 4. <ul><li>STEP 1 – </li></ul><ul><li>DEPLOY THE DEMO ON THE CLOUD </li></ul>
  5. 5. How to Experience Automatic Scaling? <ul><li>Click Deploy </li></ul><ul><li>Click Refresh Status </li></ul><ul><li>Wait until application status = </li></ul>Deployed Expected waiting time: ~7 min In the meantime let’s study the stock demo architecture…
  6. 6. <ul><li>STEP 2 – </li></ul><ul><li>STOCK DEMO ARCHITECTURE </li></ul>
  7. 7. Architecture – Processor Space <ul><li>Stock feeder simulates stock price changes </li></ul><ul><li>Processor analyzes data as it arrives (price change delta) </li></ul>Processor (Code + Data) Write Data
  8. 8. <ul><li>Stock data exposed to web browser with AJAX </li></ul>Architecture – Embedded Web Server Web Load-Balancer http:// http:// Read Data (SQL Query), Get Statistics (Admin API) Write Data Processor (Code + Data)
  9. 9. Stock Application Home Page Stock data exposed via REST
  10. 10. Stock Application Home Page <ul><li>Map/Reduce query via REST </li></ul>

  14. 14. Web Container Auto-Scaling Load Balancer monitors web availability Web Web Load-Balancer
  15. 15. Web Web Web Load-Balancer Web Container Auto-Scaling A new machine is started when the requests-per-second threshold is breached
  16. 16. Increase Load – Auto-scale-out Click View Stocks twice A total of 3 “View Stocks” pages are open. Note that the gauge is above threshold.
  17. 17. Increase Load – Auto-scale-out Wait for a machine to start automatically.
  18. 18. Increase Load – Auto-scale-out When the machine starts, the number of web Processing Units (PUs) increases from 2 to 3
  19. 19. Decrease Load – Auto-scale-in Close 2 “View Stocks” pages (leave only 1 open) Note the gauge is below threshold
  20. 20. Decrease Load – Auto-scale-in Wait until a Web_Container machine is automatically terminated (scaling in back to 2 machines). This might take a few minutes
  21. 21. Step 3 – Recap <ul><li>Increase load by starting additional web pages  Web server scales out </li></ul><ul><li>Decrease load by closing the additional pages  Web server scales in </li></ul>
