Cloud Agent Memory overview

Cloud Agent Memory as a cross-cutting topic — managed cloud services that provide persistent memory storage for AI agents without requiring self-hosted infrastructure. Covers Cloudflare Agent Memory (Durable Objects + Vectorize, REST API, team-shared profiles), Vercel AI SDK Memory (storage-adapter-backed, Next.js-native), Databricks AI Memory (notebook and agent memory with Unity Catalog governance), and hosted tiers of Mem0 and Zep. The key trade-offs vs local-file memory are operational simplicity (no infrastructure to run), cross-device access (memories available from any client), and cross-team sharing (org-scoped namespaces), offset by cloud dependency, latency for retrieval, and vendor lock-in. Cloud memory is particularly valuable for long-lived agents (Devin sessions, multi-day workflows) where local state is insufficient.
