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 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."

    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.
