What is DP-420?
Microsoft's certification for developers building on Azure Cosmos DB, its globally distributed NoSQL database: data modelling and partitioning, querying, performance and cost, and using Cosmos DB as the store for retrieval and agent memory in AI applications.
Skills it covers
- Azure Cosmos DB data modelling
- Partitioning and distribution
- RAG and vector retrieval
- Agent memory
- Performance and cost optimisation
Is DP-420 worth it? The Crydd Verdict
CS 56Choose it if
You build applications on Cosmos DB, or the data layer for AI agents on Azure.
Consider alternatives if
Your data is relational: DP-800. Outside Azure, MongoDB's Associate Developer covers document databases.
Why we say so
Cosmos DB is a common backbone for large-scale Azure apps, and its new AI focus covers the memory and retrieval layer most agent systems need.
Market demand
Cosmos DB skills are requested in Azure-heavy development teams; the certification's rename to an AI developer credential reflects demand for agent and RAG back ends.
