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.

Good GUI, easy to learn, and simple to install

The architecture is complex. I do understand that. However, the GUI is very user-friendly. Sometimes all these things are a little difficult to understand for a person who is not experienced in Couchbase. There is a constant requirement to upgrade the versions. We need to constantly keep on upgrading the latest version for the newest one. Currently, we are dealing with an issue where some of the servers are on the 6.5 version, and a few have moved to 7.5. So we are in a mixed mode right now. We are having a high IO issue on our servers, which we are already dealing with. We have these cases with Couchbase, with Red Hat, et cetera. We feel like this constant need to upgrade is something that is very mundane yet a very difficult task. If you have three clusters, which have around thirty nodes, the data is quite sensitive. Whenever there is Couchbase upgrade that is going on, we see that our SR is dropped. The purchase rate and success rate drop. This affects our business and the clients. Rebalancing could be improved. I find it to be a very slow process when it comes to rebalancing the clusters. If you talk about other architectures like Oracle, they are pretty fast. Couchbase is a little slower. Rebalancing, taking the node out, doing the upgrade, putting it back, rebalancing it, is a very difficult and cumbersome. For Oracle, we have been running on version 19.5 for the past five years. There were absolutely no issues. Yet for Couchbase, every six months, we have to go do the upgrade.

Quotes from Members

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

Pros

"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."

"Postgres has helped us innovate and stay competitive."

"Compared to my previous expenses for maintaining an on-premise PostgreSQL database, Azure Database for PostgreSQL is far easier, far simpler, and far cheaper in my opinion."

"Azure Database for PostgreSQL has impacted our ability to innovate and stay competitive in our industry by helping our developers understand what features need to be used so they can deliver the customer use case much faster, get the value out faster, and once you get the value out faster, you are ahead of the competition."

"I rate Azure Database for PostgreSQL 10 out of 10."

"The effective integration of Postgres with Microsoft products, especially with the inclusion of AI features in Azure AI, is significant for our applications."

"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."

"I rate Azure Database for PostgreSQL 10 out of 10."

Cons

"While the flexibility of the server for financial reasons is understandable, better switching between primary and backup would make transitions smoother."

"Azure Database for PostgreSQL has not really helped reduce infrastructure costs at my company."

"I do not know how Azure Database for PostgreSQL can be improved or what additional features I would prefer to see. There may be some pain points that would be valuable to fix."

"Azure Database for PostgreSQL has not helped reduce infrastructure costs for me or my clients."

"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."

"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."

"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."

"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)."

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."
