What is MongoDB?

MongoDB is an open source document-oriented database system. It is part of the NoSQL family of database systems. Instead of storing data in tables as is done in a "classical" relational database, MongoDB stores structured data as JSON-like documents with dynamic schemas (MongoDB calls the format…

Features

NoSQL Databases

NoSQL databases are designed to be used across large distrusted systems. They are notably much more scalable and much faster and handling very large data loads than traditional relational databases.

Azure Cosmos DB is great for hosting MongoDB within the Azure ecosystem

Use Cases and Deployment Scope
Because I like having the option to easily import and export the data using MongoDB Compass and other similar software, I primarily use Azure Cosmos DB for MongoDB. This allows me to avoid being locked into a particular vendor, and I also like that it can be run as a serverless solution, which allows me to manage costs and pay only for what I actually use.
Pros and Cons
  • Serverless Database
  • MongoDB management
  • Easy to work with SDKs for multiple programming languages
  • There are some areas where you can't leverage MongoDB within Azure.
Likelihood to Recommend
Like any NoSQL database, whether it's MongoDB or not, it's best suited for unstructured data. It's also well suited for storing raw data before processing it and performing any type of ETL on the data.

Use Cases and Deployment Scope
Azure Cosmos is used in a department that does a lot of analytics work and deals with big data. Typically we have systems hosted in AWS or Azure. The ones hosted in Azure datacenters rely on Azure Cosmos databases. That being said, the downstream users are scattered globally. Azure Cosmos DB is fast and reliable.
Pros and Cons
  • Highly available
  • Seamless service with low latency
  • Can be accessed through API
  • 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.

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.
Return on Investment
  • Expensive but works if your infra is on Azure data center.
  • No latency and nearly no downtime.
  • Takes time for end users to adapt.
Alternatives Considered
We evaluated Mongo DB and Amazon Redshift. In the end, we decided to have both Redshift and Cosmos but for different app stacks. For apps hosted on Azure, Cosmos plays a very important role. Also from a support standpoint, Microsoft offers very good service and an equally good knowledge base and community.

Usability

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.
Support Rating
10
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.

Use Cases and Deployment Scope
We use Azure Cosmos DB as our preferred NoSQL store for custom application development for our clients. It solves many of the onboarding hurdles for graph databases in particular, and the automatic indexing features make it ideal for a variety of scenarios across document and table storage as well. We rely on Cosmos DB when we need high availability, globally-distributed access with very low latency, and always-ready compute over data. In the past two years, I've found our team moving away from relational databases more and more as we're discovering ways to apply NoSQL much more cost-effectively than what could be done with an RDBMS.
Pros and Cons
  • 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.
  • 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.

Cosmos DB is hands-down the most flexible and performant way to store and access data related to the functionality of your applications. If you don't really need a 3rd-normal-form relational schema, and if you're not working on a (hot or cold) big data analytics scenario, then you should almost definitely be using Cosmos DB! The only major exception is if your use case can be addressed with some thoughtful planning and use of plain old Azure Storage, which might not get a lot of attention but is still a rock-solid platform.
Return on Investment
  • 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
Alternatives Considered
Cosmos DB is unique in the industry as a true multi-model, cloud-native database engine that comes with solutions for geo-redundancy, multi-master writes, (globally!) low latency, and cost-effective hosting built in. I've yet to see anything else that even comes close to the power that Cosmos DB packs into its solution. The simplicity and tooling support are nice bonus features as well.

Cosmos DB has such a head start and unique position in the market, backed as it is by Microsoft's global backbone network, that it's hard to imagine any other solution coming close to it in terms of overall capabilities. While it's not the right fit for every situation, whenever Cosmos DB is a candidate it should probably be your first choice.
