Pros
"Migrations are easy using this product."

More Amazon DocumentDB Pros →

"It is a cloud-based solution that is easy to deploy, easy to access, and provides users with more features compared to other clouds like AWS and GCP.""The product has a lot of useful features that are there and ready to use, it's also very easy to use.""Cosmos DB is stable and easy to use.""It works reasonably fast. You can retain the original format of the document as received by the third-party system.""Cosmos is a PaaS, so you don't need to worry about infrastructure and hosting. It has various APIs that allow it to integrate with other solutions. For example, we are using a MongoDB-compatible API for customers, which makes it easier for developers on the team who previously used MongoDB or are accustomed to the old document storage paradigm.""The most valuable features of Microsoft Azure Cosmos DB were the general infrastructure, ease to use, and interface.""Since it's a managed service, Azure backend handles scalability. From a user's perspective, we don't need to worry about scalability.""It is a NoSQL database."

Cons
"There's a bit of a learning curve at the beginning."

More Amazon DocumentDB Cons →

"The solution cannot join two databases like Oracle or SQL Server.""I would like the speed of transferring data to be improved.""The query is a little complex. SQL server should have more options. But the query should be better.""It would be ideal if we could integrate Cosmos DB with our Databricks. At this point, that's not possible.""The built-in integration of the solution is tight.""At this stage, we would like more enterprise support. We use MongoDB a lot, and we're trying to get rid of MongoDB. So, I would like to see more features in the Cosmos DB API for MongoDB space.""I don't think Cosmos DB has improved our organization. People are using it, but I'm not sure it's the best solution. For one, it's costly. Also, there are other issues with it. You cannot get all the records simultaneously. You can only get it in chunks of 1,500 maximum.""Sometimes, the solution's access request takes time, which should be improved."

Pricing and Cost Advice
Information Not Available
  • "Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
  • "There is a licensing fee."
  • "For the cloud, we don't pay for the license, but for the on-prem versions, we do pay."
  • "Cosmos DB is a PaaS, so there are no upfront costs for infrastructure. There are only subscriptions you pay for Azure and things like that. But it's a PaaS, so it's a subscription service. The license isn't perpetual, and the cost might seem expensive on its face, but you have to look at the upkeep for infrastructure and what you're saving."
  • "The price of Microsoft Azure Cosmos DB could be a bit lower."
  • "The cost is the biggest limitation of this solution."
  • "Azure is a pay as you go subscription."
  • "The RU's use case determines our license fees."

    Overview

    Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads.

    Amazon DocumentDB is designed from the ground-up to give you the performance, scalability, and availability you need when operating mission-critical MongoDB workloads at scale. In Amazon DocumentDB, the storage and compute are decoupled, allowing each to scale independently, and you can increase the read capacity to millions of requests per second by adding up to 15 low latency read replicas in minutes, regardless of the size of your data.

    Amazon DocumentDB is designed for 99.99% availability and replicates six copies of your data across three AWS Availability Zones (AZs). You can use AWS Database Migration Service (DMS) for free (for six months) to easily migrate their on-premises or Amazon Elastic Compute Cloud (EC2) MongoDB databases to Amazon DocumentDB with virtually no downtime.

    DocumentDB is a fully managed NoSQL database service built for fast and predictable performance, high availability, elastic scaling, global distribution, and ease of development. As a schema-free NoSQL database, DocumentDB provides rich and familiar SQL query capabilities with consistent low latencies on JSON data - ensuring that 99% of your reads are served under 10 milliseconds and 99% of your writes are served under 15 milliseconds. These unique benefits make DocumentDB a great fit for web, mobile, gaming, and IoT, and many other applications that need seamless scale and global replication.
