Cosmos DB Adds a MongoDB vCore Option: More Like On-Premises

• Azure Cosmos DB for MongoDB’s new virtual core (vCore) deployment option offers an alternative to the default Request Unit deployment.
• It provides better performance for certain workloads and a better destination for lift-and-shift migrations.
• It also removes some cost and feature barriers that may have prevented customer adoption.

Azure Cosmos DB has introduced a second MongoDB deployment option, giving customers a solution that is more like on-premises. Called MongoDB vCore deployment, the new option is based on VMs and provides greater isolation, a lower-cost entry point, and a more familiar option for migrating existing applications. It also adds features for AI-based search and complex queries that are not supported in the other MongoDB deployment option. The new MongoDB vCore deployment option competes with MongoDB’s proprietary Atlas, a popular cloud MongoDB cluster service.
