Azure Cosmos DB
NoSQL platforms are very useful when it comes to security, speed, accuracy, high accessibility with high read and write power. Everything is managed under the cloud and we have the various capabilities of Azure and support for Microsoft products with us. Flexibility in price and variety of features, as well as real-time results, are some of the popular [features] of this platform.

Redis has been a great investment for our organization as we needed a solution for high speed data caching. The ramp up and integration was quite easy.Redis handles automatic failover internally, so no crashes provides high availability.On the fly scaling scale to more/less cores and memory as and when needed.

- 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.

- 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
- Expensive, so be careful of the use case.
- We had a thought time migrating from traditional DBs to Cosmos. Azure should provide a seamless platform for the migration of data from on-premises to cloud.

- 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.

It's efficient, easy to scale, and works. We do have to do a bit of administration, but less now than when we started with this a couple of years ago. Microsoft continues to improve its self-management capability.

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.

It has very good compatibility and adaptability with other APIs and developers can safely create new apps because it is compatible with various tools and can be easily managed and run under the cloud, and in terms of security, it is one of the best of its kind, which is very powerful and excellent.

It is quite simple to set up for the purpose of managing user sessions in the backend. It can be easily integrated with other products or technologies, such as Spring in Java. If you need to actually display the data stored in Redis in your application this is a bit difficult to understand initially but is possible.

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.

Azure Cosmos DB
Azure Cosmos DB has the benefit of having multi-master key tenancy compared to Redis and Mongo. Reads are just as fast, if not faster than Mongo. However, the distribution of writes (i.e. ACID transactions) isn't as high as Google Cloud Spanner or CouchDB. Azure Cosmos DB writes slower than Cassandra, but with Cosmos, we do not have to worry about replication or tools like Zookeeper to handle it. Azure Cosmos DB has it built-in.

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.

- 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.

- 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.
