Azure Cosmos DB

If you need to store high volumes/velocity of unstructured data, Azure Cosmos DB definitely worth looking at.

Redis is great at at reducing your reliance on SQL and the cost associated with running a SQL infrastructure.We have been able to scale out and improve performance on database requests. Reliability has also great improved over running a SQL infrastructure

Pros

Azure Cosmos DB

  • Turn-key geo-redundancy with multi-master writes is unprecedented and unparalleled in the industry!
  • Guaranteed low latency makes Cosmos DB an excellent fit for most of our performance-intensive situations.
  • The tunable consistency model simplifies so many challenges in distributed systems engineering that otherwise require advanced knowledge of computer science topics. I continue to be impressed at how Cosmos DB has abstracted away so much complexity.

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

  • ANSI SQL support
  • Pure ACIDity support

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.

Excellent Customer Service which is the key thing from Microsoft. Another big advantage is their documentation and tech support and meeting industry standards.

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.

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.

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.

Our development and administration teams are just more familiar with the Microsoft Stack, and there was very little additional knowledge required to put this into production.

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

  • Tremendously reduced our time-to-market with solutions built on graph databases
  • Helped our team to think more broadly about data by making NoSQL options much more accessible
  • Saved us significant effort on geo-replication and global availability
Lars Kemmann | 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.
