Cache invalidation is often said to be a hard problem to solve. I don't think this is true in the context of software systems. Regardless of which caching strategies you use (Write-Through or Cache Aside), the key is to have well-defined boundaries. Other boundaries cannot be modifying data within another boundary directly at the database level. They must access it via the exposed API that forces cache invalidation or updating. Cache Invalidation doesn't need to be a difficult problem.
