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.

Redis

Perfect solution for caching needs. If you have a bottleneck due to frequent data access to your database, then Redis can really help you by diverting those traffic away from your database. Its key/value pair structure also makes data lookup very efficient, providing excellent performance.

Pros

Azure Cosmos DB

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

Redis

  • Easy for developers to understand. Unlike Riak, which I've used in the past, it's fast without having to worry about eventual consistency.
  • Reliable. With a proper multi-node configuration, it can handle failover instantly.
  • Configurable. We primarily still use Memcache for caching but one of the teams uses Redis for both long-term storage and temporary expiry keys without taking on another external dependency.
  • Fast. We process tens of thousands of RPS and it doesn't skip a beat.

Cons

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.

Redis

  • We had some difficulty scaling Redis without it becoming prohibitively expensive.
  • Redis has very simple search capabilities, which means its not suitable for all use cases.
  • Redis doesn't have good native support for storing data in object form and many libraries built over it return data as a string, meaning you need build your own serialization layer over it.

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.

We will definitely continue using Redis because:1. It is free and open source.2. We already use it in so many applications, it will be hard for us to let go.3. There isn't another competitive product that we know of that gives a better performance.4. We never had any major issues with Redis, so no point turning our backs.

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.

Redis has been around for very long and it is good at what it does. It proved to be very valuable in my use case for interfacing between two applications with very little code as it has drivers for almost every language out there and the community support is really good.

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.

The support team has always been excellent in handling our mostly questions, rarely problems. They are responsive, find the solution and get us moving forward again. I have never had to escalate a case with them. They have always solved our problems in a very timely manner. I highly commend the support team.

Alternatives Considered

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.

Redis

We are big users of MySQL and PostgreSQL. We were looking at replacing our aging web page caching technology and found that we could do it in SQL, but there was a NoSQL movement happening at the time. We dabbled a bit in the NoSQL scene just to get an idea of what it was about and whether it was for us. We tried a bunch, but I can only seem to remember Mongo and Couch. Mongo had big issues early on that drove us to Redis and we couldn't quite figure out how to deploy couch.

Return on Investment

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.
Anonymous | TrustRadius Reviewer

Redis

  • Redis has helped us increase our throughput and server data to a growing amount of traffic while keeping our app fast. We couldn't have grown without the ability to easily cache data that Redis provides.
  • Redis has helped us decrease the load on our database. By being able to scale up and cache important data, we reduce the load on our database reducing costs and infra issues.
  • Running a Redis node on something like AWS can be costly, but it is often a requirement for scaling a company. If you need data quickly and your business is already a positive ROI, Redis is worth the investment.
