There is a hierarchy of ways to access and store data in a computer system. The cheapest, slowest way to store and retrieve data is disk. On the faster end, we have memory. As we architect systems with increasing complexity, we have additional considerations–network latency, transient compute nodes, and numerous caching layers.

Apache Geode is a distributed, in-memory system for the JVM. It provides fast data storage and retrieval. Swapnil Bawaskar is an engineer who works on Geode, and he joins the show today to explain the architecture of Geode, and how Geode is different from other in-memory systems that get used for caching, such as memcache or Redis.
