Internet environments for consumer-facing applications routinely demand high throughput and sub-millisecond latencies for read/write transactions against terabytes of data, and service-level agreements demand 100% uptime. This session will review 10 proven practices for ensuring the high performance and availability that interactive Internet applications demand—even during power outages or natural disasters. These real-world lessons come from supporting the large-scale, multiple data center deployments of CTOs delivering platforms for the high-stakes ad sector, where speed means responses in 5 milliseconds or less, scale ranges from 200,000 to 2 million TPS against terabytes of data, and downtime is not an option. The lessons include:

1. When scaling, keep it the architecture simple, so there are fewer points of failure. For instance, load balancers may fail at high transaction rates even as the database is cruising.

2. Provide full end-to-end automation. People make mistakes, and anything that’s not automated will have production issues.

3. Keep the system asynchronous; otherwise one small failure will quickly snowball into an avalanche of degradation.

4. Keep metrics of everything, because scale tends to creep up from behind, and no one wants to be caught blind.

5. Ensure full intra-data center redundancy because servers fail…often.

6. Extend full data redundancy across multiple data centers, so storms like Sandy don’t put operations out of commission.

7. Have a back-up plan for a remote graceful shutdown that accounts for IP-based security.

8. Make sure code is testable, so there’s a way to let the world know what’s going on.

9. Divide intelligence into online and offline, so all the heavy lifting with predictive modeling is offline.

10. Use the right data management tool for the job; too often “all-in-one” means mediocre for all.
