Lets look into a how to High Performance Network Programming using Java. The slide goes through various topics like:
- Sync vs Async I/O ( includes sockets, buffers, etc..)
- Garbage Collection (advantages / disadvantages)
- Choosing a Framework ( Scala / Cloujure etc..)
- TCP RTO (retransmission timeout)
- UDP / TLS / HTTPS ( tweaking)
- Small compute devices
- EC2
Conclusion:
- Failing Well
- Scale vertically and horizontally
- Scale vertically but remember...
- We can reliably take one Java process up to 990K open connections
- What happens when that one process fails?
- What happens when you need to do maintenance?
