But it’s not easy: to pull this off, VFX studios need to build and operate serious technical infrastructure (compute, storage, networking, and software licensing), otherwise known as a “ render farm.” Many shows have needs that exceed 100,000 frames, so aggregate rendering time can impact the timely delivery of a show on Netflix.

The Solution: Distributed Caching. A widely used technology called distributed caching meets this need by storing frequently accessed data in memory on a server farm instead of within a database. This speeds up accesses and updates while offloading back-end database servers. Let’s take a look at some of these capabilities.
