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.

Have achieved excellent performance and seamless integration with effective cost control in cloud solutions

When customers are migrating from Oracle Exadata Express Cloud Service and need to remove some of their test and development environment, what happens in normal virtualization is that they can just switch it off, but in ExaCS, they need to terminate the entire thing. Most of the customers are not aware of this, so they keep spending money even if they want to shut down their UAT environment or development environment, so Oracle needs to make it simpler in terms of reducing the bill on ExaCS when customers want to shut down certain environments. Today, you have to terminate the entire VM, and only then your billing will stop. The only functionality I would expect from Oracle Exadata Express Cloud Service is that if Oracle is able to support Oracle MySQL Enterprise also on Exadata, that will solve a lot of problems.

Quotes from Members

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

Pros

"Microsoft Azure Cosmos DB is a Microsoft solution specifically, but we can develop with different developer kits for different databases."

"The solution's read capacity and write access functions are very fast so users don't have to wait when fetching or displaying data on a screen."

"It is a NoSQL database."

"The most valuable features of Microsoft Azure Cosmos DB were the general infrastructure, ease to use, and interface."

"Microsoft Azure Cosmos DB is a good solution for distributed application requirements. We can perform multi-modeling."

"The most valuable feature of the solution is that it is scalable with multiple master files."

"I appreciate Microsoft Azure Cosmos DB's robust document management and consistent availability."

"The best features of Microsoft Azure Cosmos DB include the speed to query data; as long as you index properly, retrieving data is fast and lightweight."

More Microsoft Azure Cosmos DB pros

"In the cloud, Exadata is more scalable. The on-prem version was limited. It wasn't that scalable because it only came in a quarter rack, half rack, and full rack. In the cloud, it scales to what you need."

"The performance of the tool is valuable."

"I like that Oracle Exadata Express Cloud Service is easier to use and is a cost-saving solution because you won't need to hire people to run and maintain it."

"One of the most valuable parts of the solution is the high availability within the system and the performance enhancement without making any changes or fine-tuning the databases."

"It is a scalable product."

"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."

"Having the prediction happen in the modular format allows you to start with a lower version of Exadata and then you can keep on upgrading it as per your requirement."

"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."

Cons

"At this stage, we would like more enterprise support. We use MongoDB a lot, and we're trying to get rid of MongoDB. So, I would like to see more features in the Cosmos DB API for MongoDB space."

"A further simple application is required for Brazil."

"Continuing to educate customers on how they can take better advantage of Microsoft Azure Cosmos DB without having to completely rewrite their entire application paradigm would be beneficial. They can help them understand that there are multiple options to interact with it. They do not necessarily have to start from scratch. They can refactor their existing application to be able to use it better."

"The price can always be lower, but currently, it's not a problem."

"I would give a low rating to Microsoft support, as whenever I talked to them, I never got a solution. I had to guide them."

"The only area Microsoft Azure Cosmos DB can improve on is its documentation; while it is solid and very useful, enhancements in the indexing documentation would help users save costs and make it more cost-effective."

"I am disappointed with the lack of compatibility of the Microsoft Azure Cosmos DB emulator with Mac."

"The API compatibility has room for improvement, particularly integration with MongoDB. You have to connect to a specific flavor of MongoDB. We'd also like a richer query capability in line with the latest Mongo features. That is one thing on our wish list. The current version is good enough for our use case, but it could be improved."

More Microsoft Azure Cosmos DB cons

"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."

"The support must be faster."

"The only downside is the difficulty in monitoring, and that's why I would like to implement MySQL database."

"The customer's default choice is the on-premise version of this solution. Only when Oracle or the partners like us, can explain to customers the cloud value proposition, and if the compliance authorities allow, they can look into this cloud solution. It will take some time for Oracle to change its perception of customers' de-facto standards. Exadata used to be treated as a black box, which is not the case now. The customer is aware of what is happening inside, how the configurations have been made, and what patching has been applied. Oracle needs to market the cloud version better."

"The solution's pricing could be improved."

"Oracle's support could be better."

"The product's installation process needs improvement. It could be more accessible."

"I feel there is a need for better integration with Google Maps and Google Earth. This is crucial for me in the geographical facilities of the environment."

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."

"The pricing for Microsoft Azure Cosmos DB is good. Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective."

"Its price is very good for the basic stuff. When you go to a more complicated use case, especially when you need replication and availability zones, it gets a little costly."

"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."

"Its price is in the middle, neither too low nor too high."

"When we've budgeted for our resources, it's one of the more expensive ones, but it's still not very expensive per month."

"Its pricing structure is quite flexible."

"Cosmos DB is cost-effective when starting but requires careful management."

More Microsoft Azure Cosmos DB pricing and cost advice

"I think Oracle pricing is usually above average market price."

"The tool is not cheap, but it is not really expensive."

"The price of this solution is very comparative to others on the market. There is no direct comparison between this solution and with something else because I do not see any other similar product."
