Real-time messaging has transformed customer updates and now powers responsive AI experiences
The primary benefits of Microsoft Azure Cosmos DB include horizontal scalability. The main advantage is that it handles data growth without requiring database redesign when traffic increases. Low latency access is another key benefit, as read and write operations are very fast, which is extremely helpful for real-time applications. Flexibility is also valuable because Microsoft Azure Cosmos DB uses JSON schema format, which contrasts with traditional table schemas that require time-consuming changes. In modernization scenarios where client requirements change rapidly, Microsoft Azure Cosmos DB offers more flexible schema design. High availability is another important feature, as it is well-suited for business-critical systems. My overall experience using Microsoft Azure Cosmos DB with other Azure services shows that it is more flexible compared to SQL Database and more readable because of its JSON format, making it easy to understand. It is more interactive because viewing the Microsoft Azure Cosmos DB schema clearly shows what is happening in the application and what will be achieved. In contrast, SQL requires writing many queries to obtain details, making Microsoft Azure Cosmos DB more suitable and flexible. My team's experience developing with Microsoft Azure Cosmos DB SDKs and APIs has been very comfortable and easy to implement. We are currently migrating .NET applications to Python-based AI solutions using Copilot, where we performed reverse engineering and are moving to forward engineering. We use APIs to connect with Microsoft Azure Cosmos DB and manage database containers and items, performing CRUD operations such as create, delete, and read operations, and querying JSON. We are using REST APIs with Python-based solutions, with a service layer and Microsoft Azure Cosmos DB integration.

With the VPC, you can run your workloads in an active state, use it for development work and for hosting SQL/Exchange Servers in IaaS; RaaS/DaaS for DR activities.
All three components of the vCloud Air are equally valuable and important, i.e., IaaS, DaaS and RaaS. I like the Virtual Private Cloud (VPC) offering compared to the Dedicated Cloud. It gives me the flexibility to utilize the pay-as-you-go option. You can run your workloads in an active state at reasonable prices. I have seen lots of companies use it for their development work, as well as for hosting SQL and Exchange Servers, i.e., in the active-passive mode instead of Replication (RaaS). Disaster Recovery is also a great feature that is affordable and easy to use. Disaster Recovery is a great component of the vCloud Air, where you can protect the on-premises cloud infrastructure, by providing self-service recovery options using the vSphere Replication. Some of the features that really stand out and I have used in my projects are: * Direct Connect: It provides high speed and private line connectivity. * Offline Data Transfer: For encrypted bulk data transport.

Quotes from Members

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

Pros

"Azure Cosmos DB's graph queries are its most valuable feature. Although I have not yet explored vector search, it's coming to Cosmos DB, and I plan to look into it. Having data in a flat file format in a document database speeds up processes, which is the primary purpose. Additionally, Cosmos DB's use of the Mongo platform makes it intuitive and cost-effective."
"The solution is extremely user-friendly and easy to navigate."
"It is non-SQL and helps to manage and manipulate data from the coding, rather than direct data and complex queries."
"The solution is scalable, and we intend to increase our usage."
"I would rate Microsoft Azure Cosmos DB a ten out of ten."
"The ability to scale automatically is very valuable. Additionally, multi-region support automatically synchronizing to a different region for multi-region applications is a cool feature. It's more of a lift with other databases to configure that extra region and set up replication, even if it's on the cloud. With Azure, it's just a button click. It's that simple."
"Cosmos DB has helped our organization handle large amounts of data."
"The most valuable features of Microsoft Azure Cosmos DB include the TTL, the ability to scale up and down as needed, and geo-replication, which comes out of the box."
"This is the part that should be making admins and CIOs smile."
"The Cloud DRaaS solution provided the organization with new levels of flexibility and cost control, together with rapid expansion capability."
"VMware Workstation has an interesting feature to manage vSphere infrastructure (and also stand-alone ESXi hosts) that is really powerful and useful, for example to avoid to install the vSphere client (or the integration plugin) just to open one VM console or to change the power status for some VM."
 

Cons

"A minor improvement would be enabling batch operations through the UI. Currently, to delete all documents in a collection, we must use an API, which some of my team finds inconvenient for admin tasks."
"In Microsoft Azure Cosmos DB, I would suggest improvements in security."
"What is missing in Microsoft Azure Cosmos DB is definitely cold storage. We know it's coming, but that's currently what is missing—the possibility to park older data in a cold tier."
"The query is a little complex. SQL server should have more options. But the query should be better."
"Azure Cosmos DB could be better for business intelligence and analytical queries."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high — and because of the stability issues."
"We would like to see advancements in AI with the ability to benchmark vector search capabilities, ensuring it answers questions accurately. During our initial implementation, we faced challenges with indexing and sorting, which are natively available in other offerings but required specific configurations in Cosmos."
"The integration with other solutions needs to improve because Cosmos DB's interoperability is lacking in some scenarios. For example, I'm currently implementing Fabric. That involves migrating from environments without apps, processing data and users, and taking them to Fabric."
"It’s a really good idea, but the current implementation is very limited: you can simply see your VMs and just open the VM console."
"I feel the user interface/portal can be improved further. I did experience timeout issues and the UI was performing slowly at times."
"I don’t think it is quite where EC2 is with regard to capabilities and features but VMware is investing a lot in vCloud Air."
 

Pricing and Cost Advice

"Cosmos DB is a PaaS, so there are no upfront costs for infrastructure. There are only subscriptions you pay for Azure and things like that. But it's a PaaS, so it's a subscription service. The license isn't perpetual, and the cost might seem expensive on its face, but you have to look at the upkeep for infrastructure and what you're saving."
"Cosmos DB is a highly cost-optimized solution when used correctly."
"Its pricing is not bad. It is good."
"Cosmos DB is expensive, and the RU-based pricing model is confusing. Although they have a serverless layer, there are deficiencies in what I can define and assign to a database. Estimating infrastructure needs is not straightforward, making it challenging to manage costs."
"There is a licensing fee."
"The cost is the biggest limitation of this solution."
"The tool is not expensive."
"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
