Azure Database for PostgreSQL can be improved in the area of elastic capabilities. One of the things we were actively looking for is the elastic feature, which was made a GA at this Ignite event. I am really happy that finally in Azure, we have a product which we can use for elastic clusters. If you are bound with a single server, then you have a vertical limit. Now you do not have any limits. As long as your use case grows, we can grow. The only thing I would maybe be thinking about is we should also allow customers to pick different node sizes for every node inside the elastic eventually. Some nodes do not need that big capacity. So that may be a nice-to-have feature, though it is not a must-have at this point.

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.

Quotes from Members

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

Pros

"I would definitely recommend Azure Database for PostgreSQL because it has many advantages for modern applications and enterprise workloads, including its open-source nature reducing licensing costs, large community support, extensive ecosystem, and robust security, backup, and high availability features, resulting in a good balance of performance, scalability, security, and cost efficiency."
"With PostgreSQL, the documentation is perfect, and using it on Microsoft is easy because there is documentation for Microsoft PostgreSQL, which I find easy to follow."
"The operational efficiency of Azure Database for PostgreSQL is good."
"The effective integration of Postgres with Microsoft products, especially with the inclusion of AI features in Azure AI, is significant for our applications."
"The most valuable features of Azure Database for PostgreSQL for us are reliability, performance, and cost, making it a good cost-benefit for us."
"The pay-as-you-go pricing model is one feature I truly appreciate."
"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"The benefits we have realized as a company from using Azure Database for PostgreSQL on Azure make the life of our customers and our solution easier."
"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."
"Microsoft Azure DocumentDB is never down because of its scalability feature."
"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%."
"We have immeasurable benefits mainly in reduced operational effort and the time saved on routine database administration."
"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."
 

Cons

"Support at best is a five out of ten."
"I rate it a seven because it sometimes takes a while to receive that first response from them, which may depend on the case."
"We had to move to a CSP. This has been a significant challenge. We experienced trouble with our CSP and had to change CSPs because we could not get the level of support we needed from them."
"Support can certainly get better."
"I would like to see improvements in Azure Database for PostgreSQL, such as more built-in performance tools, automated troubleshooting for complex performance issues, enhanced monitoring dashboards for faster root cause analysis, greater visibility, additional automation for scaling recommendations, and more integrated reporting capabilities."
"Coming from a traditional Oracle Exadata setup, all queries will run faster because Oracle has that optimization layer in between which optimizes it for you, which is why you pay a lot of money for that. When you come to Azure Database for PostgreSQL, that layer is gone."
"Azure Database for PostgreSQL can be improved in ways I'm very curious to explore with Horizon."
"My impressions of the latency and availability of Azure Database for PostgreSQL is that it is a concern that arises post-migration."
"Maybe in the future, I would like to see relationships between one document set and another document set."
"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."
"It is a bit expensive, especially concerning the elastic scale."
"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."
"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."
 

Pricing and Cost Advice

"The pricing experience is positive. Azure Database for PostgreSQL reduces the need for hardware investments, and the pay-as-you-go pricing model positively affects database-related costs by allowing us to start small and scale as needed."
"We do not pay for a full-year subscription because our usage is still at the beginning phase and not much. The pay-as-you-go model works well for us."
"There aren't any notable areas for improvement that I could see. PostgreSQL was self-sufficient with no need for additional database knowledge to maintain it."
"The pay-as-you-go pricing model plays a critical role in managing database-related costs and resource allocation. We build using Infrastructure as Code (IAC) and maintain a focus on FinOps to control Azure service costs. Some clients are pushy on price. It's critical to automate it, so we're just using it when appropriate and switching it off in certain scenarios."
