Likelihood to Recommend

Amazon DynamoDB

DynamoDB is great for two cases. The first is for services that do not experience high loads or demand high availability. DynamoDB is inexpensive, and it provides great developer velocity. The second is for applications that demand high performance, have well-understood requirements, and a narrow range of queries.

MongoDB

Not everything is suited to a NoSQL database - but where it is, I would 100% recommend MongoDB where it is suited to the use case.
    • unstructured / schemaless data
    • large datasets that benefit from partitioning right 'out of the box'
    • devops culture
    • high availability environments that benefit from HA and DR right 'out of the box'
And recommend an RDBMS in other cases.
    • highly structured data
    • able to be normalized
    • strong relationships exist between entities
    • static, slow growth, small datasets

  • Replication, simplest replication I've ever had to set up, and it works very well.
  • Performance, because you are simply retrieving documents it is very fast. I've seen people try to use it like a relational system and have issues, but if you learn how it is intended to be used you will have very little concern with performance in my experience.
  • Maps to objects because it's BSON. Serializing is a major strength of MongoDB to me. It is pretty awesome to just grab a document and have an object in memory and away you go!

Cons

  • The document oriented features are just starting out, and we'd love to see them develop to match MongoDB features.
  • Running out of provisioned throughput results in error responses. Better options for automatic scaling.

  • The resulting database is heavier than in a SQL relational database system

We use it for current databases and the cost is low enough to not justify transferring to a new technology.

It's something which does not conform to a schema and has a flexible design. Such a DB can be useful for all applications that have limited use of database or a small scale database. It can store related data under a single structure and hence can provide better performance in some circumstances.

While the setup and configuration of MongoDB is pretty straight forward, having a vendor that performs automatic backups and scales the cluster automatically is very convenient. If you do not have a system administrator or DBA familiar with MongoDB on hand, it's a very good idea to use a 3rd party vendor that specializes in MongoDB hosting. The value is very well worth it over hosting it yourself since the cost is often reasonable among providers.

Alternatives Considered

9/10 times I would recommend using MongoDB over DynamoDB. The only real benefit of DynamoDB over MongoDB is that it's already deeply nested in the Amazon ecosystem with tight integration with other AWS tools. Working with Amazons sdks is clunky compared to Mongo, it lacks a truly expressive query language, and the pricing makes your data inflexible.

MongoDB provides better performance on a big database. If you prefer to define indexes rather than a map/reduce function, MongoDB is good for you. It's quick to start it up and very easy to learn, basically no entry barrier. MongoDB's community is very welcoming.

Return on Investment

  • We were able to achieve our goal using Amazon – store every single email our system that has ever been sent in fluid database for long term recover without significantly impacting query times at scale.
  • We have been unable to effectively add additional features using the data set because of the pricing structure and incurred cost involved with performing repeated scans over the dataset.

  • MongoDB allowed us to get our initial version of our proudct out the door quicker and with less investment in time on the database end.
  • Although MongoDB allowed us a quicker release, we are now migrating away from it due to issues with clustering and performance. MongoDB requires a lot of resources to do even the most basic clustering.
