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.
Ethan Lo - PeerSpot reviewer
Infrastructuer Security at Premise Data
A stable and scalable relational database that ensures a return on investment for its users
The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically. You can change Google Cloud Spanner's resource configuration, which is done through processing units. Suppose you set up Google Cloud Spanner initially with a hundred processing units, and then you run out of resources since your database used too much CPU. In the aforementioned scenario, you can scale up or down and face no downtime in the production phase. The solution's features are important when running a company twenty-four hours, seven days a week.

Quotes from Members

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

Pros

"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."
"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."
"We use PostgreSQL to speed up application development. Our applications are ready sooner because we don't need to depend on other database teams."
"Backups are easy, resizing is quick, and the query analyzers help me find out what's happening in each of the queries."
"The flexibility that we have with the JSONB functionality allowed us to get data into the system, build the POC, get it in front of people, and then as we find needs for things to be more normally normalized, we can go back and make those changes."
"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."
"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."
"It is a very scalable solution."
"The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically."
"The application deployment in the cloud is the best feature of the infrastructure."
"Google Cloud Spanner is stable."
"We can scale the solution if we need to."
"The solution is stable and reliable."
 

Cons

"The pay-as-you-go pricing model of Azure Database for PostgreSQL has actually increased costs."
"I rate it a seven because it sometimes takes a while to receive that first response from them, which may depend on the case."
"They can offer more RAG extensions. Currently, it only has the vector search. It does not presently support knowledge graph functionalities as Neo4j does. It also does not offer some tools to improve indexing the way other vector databases offer."
"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."
"However, when I start planning for production where the service will be up for two or three years, I prefer to pay upfront, as the pay-as-you-go model becomes expensive for production use."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"For development purposes, it is fine, but on production, you need to have a check on the cost of it."
"Performance is one area that has constraints for our customers. I believe there could be improvements in the mirroring part and Change Data Capture (CDC)."
"The tool needs to improve horizontal scaling."
"I want to improve the deployment of cameras and surveillance infrastructure."
"Google came up with something called Cloud Spanner Emulator, which fails to work like the real product if I want to develop some code and run a database locally on my machine."
"The tool lacks to offer AI features."
"The cost can be a bit high."
 

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."
"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."
"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 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."
"Google Cloud Spanner is an expensive solution."
"It is expensive."
"The solution is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
