Review summaries and opinions

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

Customer Service

No sentiment score available
Sentiment score
8.2
Microsoft Azure Cosmos DB's customer support is praised for responsiveness but needs faster access to knowledgeable specialists.
The response was quick.
I would rate customer service and support a nine out of ten.
Our experience with technical support has always been great.
 

Room For Improvement

No sentiment score available
Sentiment score
4.9
Users want better SQL documentation, pricing models, performance, integrations, UI enhancements, and expanded API and developer tools.
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 first one is the ability to assign role-based access control through the Azure portal for accounts to have contributor rights.
Complex cross-partition querying, and BI/analytical tasks often necessitate moving data to other solutions like Fabric and Azure AI Search.
 

Scalability Issues

No sentiment score available
Sentiment score
7.7
Microsoft Azure Cosmos DB provides flexible, efficient scalability with global distribution, reducing costs and supporting large-scale, diverse applications.
Its scalability deserves a ten out of ten.
In cases where it has to automatically scale up to your maximum, that happens very quickly.
 

Setup Cost

No sentiment score available
Sentiment score
6.8
Azure Cosmos DB offers scalable pay-as-you-go pricing, seen as cost-effective yet potentially expensive compared to traditional RDBMS.
With so many improvements to the platform and ways to optimize, in our big enterprise deployments, Microsoft Azure Cosmos DB tends to be one of the least expensive services even though it gets a lot of use.
 

Stability Issues

No sentiment score available
Sentiment score
8.2
Microsoft Azure Cosmos DB is praised for strong reliability, scalability, and 99.999% uptime despite occasional complexity in configuration.
Microsoft Azure Cosmos DB is highly stable and built for stability and scalability.
The solution is very stable, and I cannot recall a time when Azure Cosmos DB let us down.
 

Valuable Features

No sentiment score available
Sentiment score
8.2
Microsoft Azure Cosmos DB is a scalable, secure, and cost-effective cloud database offering high performance and flexibility for developers.
After migrating applications from an SQL database to Azure Cosmos DB, the change in the organization is massive.
The most valuable feature of Microsoft Azure Cosmos DB is its ability to handle concurrency and consistency.
While we don't utilize every feature, auto-scaling has been invaluable for optimizing both cost and performance on our platform daily.

Can set it up on computer and run queries without depending on the cloud
The tool is open-source, so you don't need to pay for the software itself. However, you need to consider hardware costs and maintenance. A small company can install it on a company computer. For larger companies, you might need to hire a team for maintenance and consider data safety and privacy issues. Integrating ClickHouse with other tools in our data stack was easy. It has native connections to many tools, such as Google and Amazon cloud solutions, and can easily connect with other databases. For beginners, the ease of use depends on your background. If you're familiar with relational databases, it's easy. If not, you might need to read the documentation or ask for support.

Easy to integrate, has a shallow learning curve, and scales dynamically
Azure Cosmos DB is quick to adopt with a shallow learning curve. The average user can be operational within hours or days, handling small to medium data volumes. However, optimizing for ultra-high throughput scenarios involves a steeper learning curve, requiring substantial knowledge to master Azure Cosmos DB. Nonetheless, most users can leverage it as their operational data store with minimal effort. Our platform boasts several extensive language model features, particularly around summarization capabilities. We use vector searching in Azure Cosmos DB to facilitate the retrieval of an augmented generation model with our LLM implementation. It's a standard RAG implementation using Azure Cosmos DB. Compared to other options, a key advantage of vector indexing in Azure Cosmos DB is the ability to query documents alongside vectors. This pinpoints the precise information required for RAG in our LLM solution, granting us greater flexibility than vector searching in other Azure services. We integrated the vector database with the Azure OpenAI service for our LLM solution. The Azure AI services were simple to integrate with the vector database. There was a slight learning curve, especially as we were on the private preview of vector searching. This led to some hiccups with our existing database configurations, specifically regarding continuous backup. We couldn't enable continuous backup and vector searching simultaneously. However, this was solely due to our participation in the preview, and I'm confident this issue won't persist in the general availability release. Azure Cosmos DB is fantastic for searching large amounts of data when the data is within a single partition. Over the last two weekends, we ingested over 400 gigabytes of data into our Azure Cosmos DB database and saw no change in querying performance compared to when our database was only 20 gigabytes in size. This is impressive and powerful, but the scope is limited to those partition queries. The first benefit we've seen is increased developer productivity. Azure Cosmos DB is an easy database to work with. Its schema-less nature allows us to iterate quickly on our platform, develop new features, and store the associated data in Azure. Developers find it easy to use, eliminating the need for object-relational mapping tools and other overhead. Geographic replication and the ability to scale geographically is another advantage. This is challenging with other databases, even other NoSQL databases, but Azure Cosmos DB makes it easy. Cost optimization is a major benefit as well. We've been able to run our platform at a fraction of the infrastructure cost our customers incur when integrating with us. This allows us to focus resources on feature development and platform building rather than infrastructure maintenance. Azure Cosmos DB helped reduce the total cost of ownership. We don't need DBAs, system administrators, or typical IT staff to run the infrastructure because we can use Azure Cosmos DB as a platform or a software-as-a-service data storage solution. This makes the total cost of ownership significantly lower than any comparable solution using relational databases or other NoSQL solutions like MongoDB. We enable auto-scaling on all of our Azure Cosmos DB resources, which helps us achieve cost optimizations.
