Improves database performance, supports AI integration, and accelerates customer-focused innovation
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.

I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella. I would say that there is a need for developer experience enhancements, including a simpler user interface, better debugging, SQL++ guidance, and more visibility into granular workload-level costs while reporting. Couchbase Capella can improve the accuracy and reliability of its AI output. Though it is not guaranteed that the large language model answer will be correct, improvements can be made by grounding the large language models and controlling parameters such as temperature to provide better results.

Quotes from Members

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

Pros

"In terms of integration, we already have SharePoint online, and we're starting to explore PowerApps and PowerFlow. It's all seamless. The ease of integrating SQL and licensing purposes plays a significant role, making it a comfortable choice for the organization."
"PostgresSQL is acknowledged as an incredibly powerful industry leader. We've built critical pieces of national infrastructure in the UK that rely on Postgres. A version of Postgres on Azure that's easy to adopt enables us to innovate. The addition of AI extensions is even more exciting. It's a significant opportunity for us."
"Azure Database for PostgreSQL has influenced my application development process by enabling me to take some of what we used to do on-premises, with PostgreSQL hosted in virtual machines, and transition that process into a SaaS solution."
"Azure Database has become easier to use over time."
"What I appreciate most about Azure Database for PostgreSQL is not one particular feature; I think it is the use case and the facility to have a single pane of glass for managing what is on the edge, what is on the cloud, especially now with Azure Local as well."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"I rate Azure Database for PostgreSQL 10 out of 10."
"Our organization's database uptime has improved after implementing Azure Database for PostgreSQL, particularly with the flexible server's redundant configuration capabilities, which allow for failovers and read-only configurations."
"The way the nodes are managed is interesting."
"For specifics, I can say that performance is 80% faster, with a four-fold increase in throughput requests and application availability uptime rising from 99.9% to 99.9999%, and the application can now handle three times more traffic."
"The initial setup was straightforward."
 

Cons

"There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality. It does not auto-heal or self-heal in such situations."
"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."
"I believe Azure Database for PostgreSQL can be improved by allowing features that are only enabled or configured during creation to be configurable without redeploying the entire database, a process which can impact our customers if it involves an application outage."
"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."
"Azure Database for PostgreSQL has not helped reduce infrastructure costs for me or my clients."
"For development purposes, it is fine, but on production, you need to have a check on the cost of it."
"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 product could be improved by including a log section for tracking activities, enhancing database integration, and providing more transparency regarding pricing and monitoring activities."
"I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella."
"Rebalancing could be improved."
 

Pricing and Cost Advice

"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."
"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."
