Jeremiah Peschka with a great a set of Notes on Scalability, just in case you do reach your wildest expectations of success:
- Build it to Break. Plan for the fact that everything you make is going to break. Design in layers that are independent and redundant.
- Everything is a Feature. Your application is a set of features created by a series of conscious choices made by considering trade-offs.
- Scale Out, Not Up. Purchasing more hardware is easier than coding and managing horizontal resources.
- Buy More Storage. Large numbers of smaller, faster drives have more IOPS than fewer, larger drives.
- You’re Going to Do It Wrong. Be prepared to iterate on your ideas. You will make mistakes. Be prepared to re-write code and to quickly move on to the next idea.
