 ## Azure Cosmos DB for MongoDB vs MongoDB Atlas
 
-| Feature | Azure Cosmos DB for MongoDB | Vendor-managed MongoDB Atlas |
+| Feature | Azure Cosmos DB for MongoDB | MongoDB Atlas by MongoDB, Inc |
 |---------|---------|----------------------------------|
 | MongoDB wire protocol | Yes | Yes |
 | Compatible with MongoDB tools and drivers | Yes | Yes |
-| Global Distribution | Yes, [globally distributed](../distribute-data-globally.md) with automatic and fast data replication across any number of Azure regions | Yes, globally distributed with manual and scheduled data replication across any number of cloud providers or regions |
-| SLA covers cloud platform | Yes | No. "Services, hardware, or software provided by a third party, such as cloud platform services on which MongoDB Atlas runs are not covered" |
-| 99.999% availability SLA | [Yes](../high-availability.md) | No |
-| Instantaneous Scaling | Yes, [database instantaneously scales](../provision-throughput-autoscale.md) with zero performance impact on your applications | No, requires 1+ hours to vertically scale up and 24+ hours to vertically scale down. Performance impact during scale up may be noticeable |
-| True active-active clusters | Yes, with [multi-primary writes](./how-to-configure-multi-region-write.md). Data for the same shard can be written to multiple regions  | No |
-| Vector Search for AI applications | Yes, with [Azure Cosmos DB for MongoDB vCore Vector Search](./vcore/vector-search.md) | Yes |
