Amazon DynamoDB

It is ideal for those projects where you need to store a large amount of data, but you do not know how many will be so you need the database to increase its storage capacity together with the number of users, without having to spend extra money, it also has a great potential thanks to the fast connection it offers, so the data travels at high speed, and this speeds up the performance of the applications, excellent for projects where non-relational databases are used and what matters is to store large quantities of information and use them at high speed.

Azure Cosmos DB

Cosmos DB is fast, reliable, and highly available. We use it mostly in analytics and applications that leverage big data hosted on the Azure Datacenter. If you have a virtual private cloud in one of Azure sites, then you would definitely need Cosmos. It works well with on-premises applications and offers little to no latency.

Pros

Amazon DynamoDB

  • It's very easy to get started, creating a table with a partition/sort key and you're on your way.
  • You can scale up and down your read/write IO as needed.
  • You can store structured and unstructured data.
  • It works great with Web Development as it's JSON based.
Bob Smith | TrustRadius Reviewer

Azure Cosmos DB

  • Injects unstructured data at a very high speed.
  • No real need for administrative work, it indexes everything on it's own.

Cons

Amazon DynamoDB

  • Complex searching (no support for case-insensitive or full-text search).
  • Only supports up to two-key indexes.
  • Requires choosing the indexes up-front when doing searches.
  • Does not have an SQL compatible query front-end.
  • No join-table support (requires putting all data into one table).
Chris Moyer | TrustRadius Reviewer

Azure Cosmos DB

  • Cosmos DB can be very expensive if you're using it for scenarios that are better completed in regular old Azure Table Storage or Blob Storage, specifically if you put some thought into your partitioning schemes. No product is a good substitute for thoughtful system design.
  • It would be helpful if I had some more insight into how many resources (DTUs) an individual query uses.
  • The auto-indexing is great, but a little mysterious -- not usually an issue but it does require some intentional thought.

We will most likely continue to use DynamoDB for certain use-cases. If we stopped using DynamoDB as often, it would likely be because we started using Aurora Serverless more. Aurora Serverless may offer similar availability, management and cost benefits while allowing developers to use their MySQL tools and experience.

The total cost of ownership is much higher than anticipated. The documentation for their API calls is still not complete. TCO did go up as a result as well. Having users learning another JQL-like language also added more complexity to it. Support of ANSI-SQL would be ideal. But the cost of managing it is much less compared to Redis, Mongo, or Cassandra.

Like I said, Cosmos is the way to go. From all of the services that Azure has, Cosmos is very robust in terms of usability. It's ever-evolving and integrates with other applications seamlessly. The interface is pretty easy to understand. I implemented various solutions for my company and Cosmos was one of them.

Microsoft is the best when it comes to after-sales support. They have a well-structured training and knowledge base portal that anyone can use. They are usually quick to respond to cases and are on point for on-call support. I have no complaints from a support standpoint. Pretty happy with the support.

Alternatives Considered

Amazon DynamoDB

We evaluated using MongoDB or Amazon DyanmoDB. For us, the biggest advantage is that there's no maintenance cost for Amazon DynamoDB. Mongo gets complicated when you setup sharding. With Amazon DynamoDB, it's literally a push of button to increase throughput. This saves time and money on DevOps resources.

Azure Cosmos DB

Azure Cosmos DB is a fully managed NoSQL database & globally distributed NoSQL database service. Its very fast and predictable performance, high availability, elastic scaling, global distribution, and ease of development DB platform compare to MongoDB.

Return on Investment

Amazon DynamoDB

  • Since the Amazon manages the instance, the amount of time a developer needs to spend configuring the database is less. For comparison, if we were to manage the same instance manually, we need to set up EC2 instance, install the DB, setup backup scripts, track backup failures, which is a great overhead for the dev. Using DynamoDB this overhead is reduced and hence having a great ROI.
  • Great documentation and easy setup makes an easy learning curve to transition to DynamoDB. Only caveat is as with any database, the data structure should be thoroughly analyzed for types of querying because there are limitations with the DynamoDB API.
  • Ties very well with rest of the Amazon eco system. Having rest of the applications in Amazon allows managing the application security a breeze.

Azure Cosmos DB

  • Azure Cosmos DB may be expensive on its own, but it was cheaper than increasing the size/power of our VMs running SQL Server instances enough to keep up with the volume and velocity of the unstructured data.
  • We got the JSON data out of our SQL Servers and they quit tipping over.
