Use distributed systems patterns to reason about retries, queues, consistency, partitions, caching, and graceful degradation.
Practise explaining technical tradeoffs in the language of reliability, security, latency, throughput, and operational cost.
Hands-on labs
Trace a web request through DNS, TLS, load balancer, application, cache, database, logs, and metrics.
Design a queue-based workflow that handles retries, duplicate messages, dead letters, and idempotency.
Compare database indexing, replication, transactions, and partitioning choices for a learner platform.
Create a capacity plan with traffic assumptions, latency targets, bottlenecks, and scaling actions.

Practice questions
Why is idempotency important in distributed systems?
Retries can cause the same request or message to run more than once, so idempotent operations prevent duplicate side effects such as double billing or repeated provisioning.
What does a cache improve, and what risk does it introduce?
A cache can reduce latency and database load, but it introduces freshness, invalidation, consistency, and capacity risks that must be managed.
