Likelihood to Recommend

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.

Redis

Redis is great at fast operations, especially set-based operations. It is great as an object storage mechanism, such as a cache server or a fast key-value object store. Redis is easily installed and maintained, and setting up clustered instances isn't too terrible. Because the basic installation is open source, it is easy to experiment with before deciding to go with Redis long term.

Redis

  • Being a non-SQL database, it does not require any structure. Perfect for unstructured data like key-value pairs.
  • Redis is extremely fault tolerant. As soon as we write a record, it gets saved to the disk, without any performance issues.
  • Redis is very lightweight. In docker it takes less than 30MB, so it is so easy to run multiple containers in cluster without taking too much power.
  • Redis has a very good query API, and they are in their website each operation is clearly mentioned with its time complexity. This gives you a clear picture of performance. We didn't in fact do any performance testing because we trusted their site with all the information.
  • Redis has a very strong community around it. We have never found an issue for which a solution didn't exist beforehand.

Cons

Amazon DynamoDB

  • There is a cost associated with creating indexes and being able to run queries.
  • It would be nice to have a thick client to be able to connect and work with DynamoDB.
  • It would be nice to be more aware of how DynamoDB functioned to be able to engineer towards optimization.

Redis

  • Redis is sponsored by Redislab which limit its functionalities. This is normal but they should push for a graphical tool for Redis monitoring. This tool is available for the enterprise edition, it would be nice to have a core version for the community
  • I don't know if Redis is available in containers, this might be interesting to have such capability

As with most Amazon Services, it isn't about renewal of DynamoDB, it's about continued use of the service with a realistic pay per value approach. If a service is viable to a business, then it is used and you can always consolidate away unused services. We will continue use of DynamoDB until it doesn't deliver as well as other technologies/services.

The benefits we've seen by implementing Redis in our applications have been tremendous. We have no reason to not keep using Redis. We will likely evaluate alternatives in the future, but not because of any shortcoming we've identified with Redis thus far. Sometimes there are better tools for certain jobs. We want to be open to new options if they meet our requirements better. So far Redis has done very well for us.

Alternatives Considered

Amazon DynamoDB

DynamoDB is more flexible than key-value stores like Redis-flavored Elasticache. They both offer high-availability. Elasticache requires a little more management, and lacks on-demand scaling and pricing. DynamoDB is not a relational database, but can replace RDS for simple use-cases, like a stateful background job. DynamoDB can be faster and much less expensive for some use-cases. Aurora Serverless is an intriguing option that I have not yet evaluated. I would consider it the time I have a use-case that DynamoDB may suit. Serverless is similarly fully-managed and offers something like on-demand pricing, but provides all the features of MySQL 5.6 and better performance than RDS/MySQL.

Return on Investment

Amazon DynamoDB

  • Dynamodb reduced the need for SRE headcount to maintain infrastructure.
  • Built in metrics dove tails with existing monitoring tooling.
  • Flexible NoSQL design allows developers to focus on business problems, rather than database design.

Redis

  • We use Redis for the purposes of routing data within our infrastructure. In this use case, we want there to be a little additional latency as possible. In this, Redis does a great job.
