MichaelJohn - PeerSpot reviewer
Very efficient for application-facing scenarios
There are several areas for improvement. Firstly, having a local development emulator or simulator for Azure Cosmos DB would be beneficial. It would be very handy to have a Docker container that developers can use locally. Although, I know there is a free tier and so on and so forth, having a local environment would be nice. For example, SQL Server is very portable. You can even install it on your machine. That is the number one thing that is missing in Azure Cosmos DB. The second improvement area is the IDE of choice. That means how you interact with Azure Cosmos DB. For example, with SQL Server, you have SQL Server Management Studio. I know there is a little bit of support for Azure Cosmos DB in Azure Data Studio, but it is not heavily advertised or it does not feel like first-class citizen support. Developer experience or developer tooling is missing in terms of interacting with the database. Better developer tools or an IDE for interacting with Azure Cosmos DB would enhance the developer experience. Lastly, there is some mixed messaging about what Azure Cosmos DB is, given its multiple APIs. There are so many Azure Cosmos DB APIs available. There is NoSQL. There are MongoDB, Gremlin, and others. There is still some mixed messaging for others who are new to Azure Cosmos DB about what Azure Cosmos DB is. Is this like MongoDB, but then there is also MongoDB in Azure Cosmos DB? I know it well, and I know that the default one is just NoSQL, but others I have interacted with over the last ten years or so get confused.

Delivers superior search and data aggregation capabilities
Neo4j helps with advanced search needs, providing good search results and aggregates compared to MongoDB. Aggregating with MongoDB can be difficult; however, with Neo4j, it's easier. Aggregating data, backing up, and creating new clusters are user-friendly from the back end. In DevOps web deployment, we noticed no database issues. We created Docker instances and set them up efficiently, managing databases up to 50 gigabytes.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The global synchronization feature of Azure Cosmos DB stands out as the most valuable for me."
"Microsoft Azure Cosmos DB is very easy to use."
"Switching to the cloud significantly improved scalability, flexibility, and uptime."
"Microsoft Azure Cosmos DB is very fast. Data retrieval and data storage are very quick."
"One of the nice features is the ability to auto-scale"
"I would rate it a ten out of ten for stability."
"It has been very efficient so far. The team has been using it for quite a while. I am new to the team, but they always talk about how efficient it is."
"The high speed of Azure Cosmos DB compared to other competitors is remarkable."
More Microsoft Azure Cosmos DB pros
"The solution's best feature is how it differs from traditional SQL databases. It's hard to map people and find those near me in SQL, which requires long, complex queries. Neo4j Graph Database makes this easier with simpler queries. It also supports more data types, like JSON, which SQL doesn't."
"Enables people to understand what the business problem is and how the technology helps."
"For now, the tool doesn't break down or stop, so it is quite stable."
"Creates the ability to visualize outputs."
"It is good for search-based tasks, providing solid search results and aggregate results."
"As a graph database, I am surprised at their performance and response time."
 

Cons

"The first one is the ability to assign role-based access control through the Azure portal for accounts to have contributor rights."
"One area for improvement is the ease of writing SQL queries and stored procedures in Microsoft Azure Cosmos DB."
"While Microsoft Azure Cosmos DB is generally easy to use, it has some limitations."
"There is room for improvement in Microsoft's maintenance aspect. For example, we had a major incident at the end of December where the entire South Central region was down for our application, causing many problems due to a lack of access to the database."
"An improvement would be a more robust functionality around updating elements on a document, or some type of procedural updates that don't require pulling the entire document."
"A better description and more guidance would help because the first time I created it, I didn't understand that a container is similar to a table in SQL."
"An improvement could include increasing the document size or providing a method to manage larger sets efficiently. If they want to keep a 2 MB limit, they should provide a way to chain multiple documents in a systematic way so that developers do not have to figure out what to do when a document is larger than 2 MB."
"The biggest problem is the learning curve and other database services like RDS."
More Microsoft Azure Cosmos DB cons
"The tool could improve by having more resources, especially for Golang, which we use. It lacks good basic libraries and doesn't have an ORM (Object-Relational Mapping) tool, which many NoSQL databases have. We thought about building an ORM for the Neo4j Graph Database but are too busy."
"So far, we have not had any issues and are happy with the product in general."
"There are concerns about performance and whether the tool can necessarily scale to provide the solution."
"For me, when the tool was deployed on an on-premises model, it was a little bit difficult the first time."
"The only problem is that the community is quite small."
 

Pricing and Cost Advice

"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"The pricing model of Microsoft Azure Cosmos DB is a bit complex."
"Cosmos DB gave us three accounts for $400. We pay according to the usage."
"Its pricing is not bad. It is good."
"We are not consuming so much yet since we are at the beginning of using this solution. I would rate the pricing of Microsoft Azure Cosmos DB a six out of ten."
"The customer had a high budget, but it turned out to be a little bit cheaper than what they expected. I am not sure how much they have spent so far, but they are satisfied with the pricing."
"Most customers like the flexibility of the pricing model, and it has not been an issue. They can start small, and the cost grows with adoption, allowing efficient management of the budget. Its pricing model has not been a concern at all for any of our customers. They understand it. It is simple enough to understand. Oftentimes, it is hard to forecast the RUs, but, in general, it has been fine."
"Its cost is transparent. Pricing depends on the transaction and data size, but overall, it is cheaper compared to hosting it on your corporate network due to other factors like power consumption."
More Microsoft Azure Cosmos DB pricing and cost advice
"The tool is not expensive."
"The solution is open source so that you can use it for free. They also offer an enterprise version with its billing. If your company is earning well, I suggest using the enterprise version. Otherwise, you can deploy it on your own cloud and pay based on usage."
