Multi-node architecture and it is good from a security point of view
I would rate the stability a seven out of ten. Most of the issues we faced during troubleshooting were due to specific bugs in the environment, and the only solution was to upgrade the database environment or services. But it is not easy to upgrade the database level when third-party applications are involved, as they are not always comfortable with upgrading. There should be some cumulative solution provided by IBM for their customers, just like other vendors. Upgrading to a certain version doesn't always resolve the issue. It might get resolved at the database level, but what about the other applications integrated with that database that are only compatible with older versions?

All Microsoft applications, whether database or analytics, are a little costlier compared to Google products, and this is a barrier that needs to be crossed so that all its applications become more affordable. For example, startups typically go for free tools. Microsoft should offer these products for free to startups or perhaps free for the first year or two years, so that startups can use these applications, and once they grow bigger and have larger revenue, they can purchase it at a reasonable cost. All Microsoft tools need to cut down on their price and have a better strategy around pricing for the masses. If you sell only to ten customers, your revenue is lesser, but if you give something for free to some customers, two years down the line they will purchase it. Microsoft Azure DocumentDB still needs the ability to connect to other analytics easily without any additional integrator. For example, if I can connect to Google Analytics or other analytics that are not Microsoft tools using this database, that would be a good source of revenue. If I have already purchased Google Analytics in my company and I need a database, and Microsoft Azure DocumentDB can very easily connect or integrate to my Google Analytics, I would not have to think twice. Cross-company application connectivity is something that needs to be worked on.

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

Pros

"The reliability is the most valuable feature. It is also user-friendly."
"Multiple business departments rely on reports and predictive analysis to make decisions for future business based on their data warehouse and Db2 network analytics tool. It helps our business department make decisions."
"Microsoft Azure DocumentDB is never down because of its scalability feature."
"We have immeasurable benefits mainly in reduced operational effort and the time saved on routine database administration."
"The most valuable feature of Microsoft Azure DocumentDB in my daily work is the speed."
"Microsoft Azure DocumentDB has positively impacted my organization by allowing us to reduce database costs by 30%."
"The most beneficial features of Microsoft Azure DocumentDB that I noticed is that it appeared to be straightforward, it was ease of use, it was not complicated compared to some of the other tools that are out there, the teams were familiar with it, and it integrated well with other Microsoft products."
"One of the most appreciated aspects of Microsoft Azure DocumentDB is the elastic scaling feature which has significantly helped manage business growth for two customers who have employed it, experiencing a dramatic rise in improvement."
 

Cons

"I would give their support a ten if they had more tutorials available."
"Nobody is going to like the price."
"In other environments like Oracle or Teradata, they provide their own solutions for troubleshooting issues. They provide built-in AI services or autonomous databases, which I don't see in the Db2 environment."
"It is a bit expensive, especially concerning the elastic scale."
"Microsoft gives you the base functionality which you can grow from, but some tools perhaps go a bit further because that is their only focus or niche."
"Maybe in the future, I would like to see relationships between one document set and another document set."
"All Microsoft applications, whether database or analytics, are a little costlier compared to Google products, and this is a barrier that needs to be crossed so that all its applications become more affordable."
"Microsoft Azure DocumentDB could be improved with more straightforward cost and performance optimization guidance, especially for understanding resource usage and selecting the right configuration for different workloads."
