Building a scalable application that has high availability is not easy and does not come automatically. To that end, this webcast focuses on five keys that will help build applications that, as their use scales upwards, availability remains high.

Here are the five keys:

  • Build your applications keeping availability in mind. Consider availability concerns during all aspects of your application construction.
  • Always think about scaling. While building your application, consider how it will perform when it has 10x the traffic it currently does. Do you need a different database strategy? What about state management? Caching?
  • Mitigate risk. All systems have vulnerability. Understand the risk your application has, and implement mitigations to reduce the likelihood and severity of the risk occurring.
  • Monitor availability. You can’t keep your application running if you don’t know how it is performing. Use application monitoring to keep an eye on how your application is performing, and generate notifications when the application performs in abnormal ways.
  • Respond to availability issues in a predictable and defined way. When a problem occurs, do you know what to do to fix the problem? Does everyone on your team know what to do? Do you have playbooks written that have standard procedures and practices for fixing common problems? Have you verified your pager rotation works as expected?
