Lessons Learned
- For high traffic websites, testing in production is the only way to get an accurate picture of capacity and performance. For large application infrastructures there are far too many ‘invisible walls’ that can show up if you only test in a lab and then try to extrapolate.
- Elastic scalability is becoming an increasingly important part of application architectures. Applications should be built so that critical business processes can be independently monitored and scaled. Being able to add capacity relatively quickly is going to be a key architecture theme in the coming year and the big players have known this for a long time. Facebook, Ebay, Intuit, and many other big web names have evangelized this design principle. Keeping things loosely coupled has a whole slew of benefits that have been advertised before, but capacity and performance are quickly moving to the front of that list.
- Real-time monitoring is critical. In order to react to capacity or performance problems, you need real-time monitoring in place. This monitoring should tie in to your key business processes and functional areas, and needs to be as real time as possible.
