Netflix recently announced its expansion into the global market, and Faisal Siddiqi covered the global caching system, EVCache, that was developed to handle global and cross-region replication requirements. During EVCache development, the team had to handle many distributed systems requirements, such as reliability, low latency, and asynchrony (but, interestingly, not strong global consistency). Faisal also dived into the multiple challenges they faced as they developed and iterated on EVCache — such as understanding how to best scale Apache Kafka and deal with AWS packets-per-second limits.
