Considered Both Products
Azure Cosmos DB
Chose Azure Cosmos DB
Azure Cosmos DB for MongoDB is more affordable than many other solutions and works incredibly well if you're within the Azure ecosystem.
Chose Azure Cosmos DB
Because we often use Microsoft products for large corporate projects and other customer projects, and compatibility and integration are important to us, we used this platform, which in addition to very high security, has a very good response speed, also, building modern …
Chose Azure Cosmos DB
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 …
Chose Azure Cosmos DB
Azure Cosmos DB has the benefit of having multi-master key tenancy compared to Redis and Mongo. Reads are just as fast, if not faster than Mongo. However, the distribution of writes (i.e. ACID transactions) isn't as high as Google Cloud Spanner or CouchDB. Azure Cosmos DB …
Chose Azure Cosmos DB
Azure Cosmos DB is a fully managed NoSQL database & globally distributed NoSQL database service. Its very fast and predictable performance, high availability, elastic scaling, global distribution, and ease of development DB platform compare to MongoDB.
Chose Azure Cosmos DB
Our development and administration teams are just more familiar with the Microsoft Stack, and there was very little additional knowledge required to put this into production.
Chose Azure Cosmos DB
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 …
Azure SQL Database
Chose Azure SQL Database
We have selected it because we are using Azure Cloud and it is the best option for us to go ahead with Azure SQL Database.
Chose Azure SQL Database
The simplicity and great features and good support of Microsoft as well as the more reasonable flexible price than other competitors is one of the important reasons for choosing it.
Chose Azure SQL Database
Oracle database is "the" serious database. There really is no competition in that field. SQL Database would be a serious competitor through the ease of implementation and the "no maintenance," but since it's too expensive for "normal" use (medium to small applications), it just …
Chose Azure SQL Database
We looked at Google Cloud SQL and Amazon RDS services, but we did not want to switch to a different structure from the system we currently use.
Chose Azure SQL Database
It is very easy to setup SQL database on Azure. one can always refer to their documentation for best practices. It is highly available and scalable. It is cheaper than its alternatives and provide better performance than others. As we are using many other services of Azure for …
Chose Azure SQL Database
Amazon RDS for SQL Server is the best example to compare with Azure SQL Database since both provide a Microsoft SQL Engine to host your databases.

Amazon RDS for SQL is much more compatible with your on-premises databases than Azure SQL, the reason is that Amazon RDS for SQL …
Chose Azure SQL Database
The Azure SQL Database, compared to our on premise SQL server installation, is much easier to use in terms of seeing database diagnostics. There is a whole visualization platform that comes with the tool that will allow your database administrator to see what jobs are tying up …
Chose Azure SQL Database
Amazon's RDS offering is actually very good and is used in other parts of the company, we just have a lot of Azure experience so wanted to leverage that.
Chose Azure SQL Database
Azure SQL has a slight advantage over its rivals because it's developed by Microsoft, so it is well suited to professionals.
Chose Azure SQL Database
Being able to manage our databases in the cloud, scale quickly, and only require access to VMs made choosing Azure a no-brainer over a traditional SQL Server installation/integration. We don't have the budget or resources to integrate and maintain servers on our own, so using …
Chose Azure SQL Database
I would say MySQL in either Aurora or MariaDB form come close however, Azure SQL Database has a more streamlined approach to delivering a consistent programmability model, supported drivers and feature set.
Azure SQL Database T-SQL is advantageous and more complete than SQL …
Chose Azure SQL Database
Azure owned by Microsoft who owned SQL Server, so provided a variety of tools for easy migration/transition and from on-premises to the cloud; and management. I recommend using Azure for any on-prem SQL server databases.
Chose Azure SQL Database
Very similar product. Our company preferred to remain in the Microsoft Software Suite.
Chose Azure SQL Database
Azure SQL is a clear upgrade to SQL Server 2012 and pretty much has the advantage with all the extra features that it has. Security, queries, exporting tables, T-SQL has all improved. Transitioning 18+ years of an in-house database to the cloud was a struggle, but for the …
Chose Azure SQL Database
We moved away from Oracle and NoSQL because we had been so reliant on them for the last 25 years, the pricing was too much and we were looking for a way to cut the cord. Snowflake is just too up in the air, feels like it is soon to be just another line item to add to your Azure …
Chose Azure SQL Database
Amazon Relational Database Service is the other obvious competitor. We were already in Azure, so it's not a serious contender for our business due to that bias already, but I do personally find the marketing and documentation of RDS more intimidating to sort through.
Chose Azure SQL Database
Comparing with Amazon Aurora: Azure SQL DB is 100% compatible with SQL Server and Aurora is compatible with MySQL and PostGreSQL. Because of if, SQL DB suits large enterprises with hundreds of databases better.
Comparing with Oracle: the main issue is that Oracle will try to …
Chose Azure SQL Database
It reduces the business cost as it provides large storage capacity with massive speed. Data security is primary benefit which this product gives me.
Chose Azure SQL Database
It stacks up in different ways, for the most part, I think Microsoft is doing a really good job versus the competition. They basically started database type products from the beginning. I've always been excited about updates and can see their progress over time. Get's me really …
Chose Azure SQL Database
AWS's solution would be an alternative. I felt since we're a Window shop and already had a small investment into Azure, it was a no brainer.
Chose Azure SQL Database
It's more easy to shift and get all the services up in no time, provide best up time and monitoring easily so you can get the best services which take care of themselves. It's a better fitting for a large company size.
Chose Azure SQL Database
If you are a company that is already invested in Microsoft technologies, then the Azure suite is a better fit than the Amazon suite.
Chose Azure SQL Database
As we were early adopters with Azure and landed on the Azure PaaS (Platform as a Service), it made sense to use databases that were on the same platform as the application to save on costs. Also, we were impressed with the simplicity of Azure SQL. From a management perspective …

Your upcoming app can be built faster on a fully managed SQL database and can be moved into Azure with a few to no application code changes. Flexible and responsive server less computing and Hyperscale storage can cope with your changing requirements and one of the main benefits is the reduction in costs, which is noticeable.

Pros
  • 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.

  • Scalability is #1: if it used to be an almost no-win endeavour to try to modernize your server or migrate to other hardware, with Azure SQL Database it becomes a press of a button.
  • All the tools simply work after you are on Azure SQL Database.
  • The applications do not need changes in order to start using Azure SQL Database.
  • Hybrid Cloud scenarios will work.
  • Clustering and failover - already there.
  • You can start monitoring the use and extract performance insights in a new way in Azure.

Cons
  • When searching by default, it is case sensitive, which must be changed by default
  • In many ways, the price should be more flexible according to the requested facilities, because the price is very expensive for startup companies.
  • It is not fully compatible with most common Streaming Analytics tools applications and developers should be worked on it

  • A little slow on processing complex or large Views. We use a lot of Views to feed our BI system, and the processing time could see some improvement, IMHO.
  • Additional monitoring components would be nice too, automating some built in performance measurement tools would be a nice feature.
  • Price can always be improved as well. It’s not bad, but room for improvement.

It's efficient, easy to scale, and works. We do have to do a bit of administration, but less now than when we started with this a couple of years ago. Microsoft continues to improve its self-management capability.

This is best solution as a DBA one could expect from a service provider and as a cloud service, it removes all your hassles.

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
The support team is very responsive and we are generally satisfied with Microsoft support, in my opinion support team of a product and service is just as valuable as its quality and performance. Telephone answering, 24-hour hotline, email support and ticketing are excellent.
Read full review
We give the support a high rating simply because every time we've had issues or questions, representatives were in contact with us quickly. Without fail, our issues/questions were handled in a timely matter. That kind of response is integral when client data integrity and availability is in question. There is also a wealth of documentation for resolving issues on your own.

Oracle Database is "the" serious database. There really is no competition in that field. SQL Database would be a serious competitor through the ease of implementation and the "no maintenance," but since it's too expensive for "normal" use (medium to small applications), it just priced itself out of the market, so to speak. Nevertheless, we do have 2 or 3 large applications that are highly integrated in azure, and for those it's just too easy to use SQL Database instead of the on premise Oracle Database with VPN gateways etcetera.

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.
Read full review
  • We don't need a dedicated SQL dba because so many of the database maintenance operations are managed. A huge positive not only in budget but time constraints.
  • The ability to scale quickly is the biggest positive as our data needs change constantly.
  • Easy to migrate from legacy tools and systems, saving us on the need for redevelopment.
