The Accidental CTO by Subhash Choudhary
Came across this cool eBook The Accidental CTO written by Subhash Choudhary, the Dukaan CTO. He shares the story of scaling Dukaan from zero to a million stores, without even having a CS degree.
He will be discussing the below topics in the ebook which will be an interesting read.
- Scaling applications: How we went from thousands to millions of users without falling apart.
- Replication, sharding, caching, queues: When to use them, when not to, and what tradeoffs they carry.
- Observability as survival: Why metrics, logs, traces, SLAs, and SLOs aren’t optional — they’re lifelines.
- Resilience engineering: Circuit breakers, retries, graceful degradation — designing for failure, not against it.
- The hidden costs of cloud: Why at scale, your AWS bill can become your biggest investor, and when it makes sense to go self-hosted.
- The consistency/availability/latency triangle: Why you can never fully win, and how to navigate the tradeoffs in real systems.
I have started reading it already, and loving it so far.
