I had to explain to our CFO why we needed to spend $200K on a disaster recovery setup that we hopefully would never use. I could have talked about RTO and RPO, but instead I framed it as insurance. I showed data on how much an hour of downtime would cost us in lost revenue and customer impact, then explained that for $200K upfront and ongoing, we could recover from a regional outage in minutes instead of hours. I walked her through a scenario: if our primary data center in one region went offline, here's what customers would experience with our current setup, and here's what they'd experience with DR in place. I also explained that this wasn't theoretical—it happened to a competitor last year. She approved the budget.

77

How do you ensure high availability and disaster recovery?

Reference answer

High availability and disaster recovery are different problems, so I tackle them separately. For HA, I use redundancy at every layer—multiple instances behind a load balancer, replicated databases, auto-scaling groups that spin up replacements if instances fail. I've deployed across multiple availability zones so a single zone's failure doesn't take us down. For disaster recovery, I establish RTO and RPO targets first—how quickly do we need to recover, and how much data can we afford to lose? Then I design backward from there. We run automated daily backups of databases and critical file systems, store them in geographically separate regions, and document the recovery procedures. The critical part: I actually test these recovery plans quarterly by doing disaster recovery drills. It's revealed gaps every time, and it's better to find them in a drill than during an actual outage.

You notice CPU utilization is consistently at 85% on your application servers during peak hours. Walk me through how you'd diagnose and fix it.

Reference answer

First, I'd gather context. Is this new, or has it always been this way? Is it causing customer impact—slow response times or errors? If it's not causing problems, maybe 85% is acceptable and we just need to make sure it doesn't spike higher. Assuming it's new and causing slowdowns, I'd drill down. I'd look at application metrics—has request volume increased, or is each request using more CPU? I'd check for runaway processes using top or ps to see which process is consuming CPU. I'd also check system metrics like context switches and I/O wait. If I/O wait is high, it might not actually be the application—the server might be waiting on disk or network. Let's say I discover a recent code change caused an inefficient database query. I'd work with the developer to optimize that query or add caching. If it's sustained traffic growth, I might scale horizontally—add more servers behind the load balancer to distribute load. I'd also set auto-scaling policies so if CPU stays above 75% for five minutes, new servers automatically spin up. This prevents us from firefighting every spike.
