Drag and drop workflows have simplified data mapping and currently improve my cloud database work
The IPaaS Connector, which I have found most valuable, is part of Google Cloud SQL. Google Cloud's user interface is really good, which improves efficiency in my database operations. The UI is excellent, making it easier to understand what we are doing. Currently, I am working on IPaaS Connector, so it is really just a clickable interface without writing any code. I simply use drag and drop and connecting lines, and it is working. Google Cloud SQL's global infrastructure improves our database's latency metrics because we are using Gemini in our project. Since both are products of Google, it makes our product faster.

Collecting compliance data has become more efficient while managing unstructured inputs for reporting
The features that I find most valuable within Microsoft Azure Cosmos DB are probably the cost, as the cost optimization is good. The storage and queryability are good for what we're doing; it's a lot of unstructured data, so having a platform to put that in and then be able to harvest that data out for the reporting we do is essential. In terms of cost saving, it was probably easily 30 to 40% cheaper than doing a standard SQL, which is what we saw just on piloting and getting in there. We were initially thinking 20 to 25%, but we were probably more at the 35 to 40%. We are using Microsoft Azure Cosmos DB's hybrid search today. The value that it has added to my AI or search workloads is that I think it's optimized that process and made it easier. We have a lot of unstructured data coming from different dissimilar systems and different data sources, so correlating those things together and making sense of it has been very beneficial. Microsoft Azure Cosmos DB has had pretty good performance with searching through large amounts of data; it's been fast, and we haven't seen a lot of performance degradation while building larger queries and bringing in a large set of data. The dynamic auto-scale or serverless model from Microsoft Azure Cosmos DB has helped reduce costs and operational effort; however, it's hard to quantify how that plays out since you're using a shared service. It shifts my focus away from building, managing, and upgrading to adding value.

Quotes from Members

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

Pros

"Ease of management and the ability to oversee the statistics of your SQL."
"Google Cloud SQL enhances our AI-driven projects by providing features like query optimization and scalability for efficiently processing large datasets."
"The most valuable features are that it's easy to use, simple, and user-friendly."
"The product is scalable."
"The most valuable feature for us is the Postgres on Google Cloud SQL since it supports most of the features we need."
"What I like the most about Google Cloud SQL is that it handles the management, which allows us to concentrate on our applications."
"Licensing is not applicable; pricing is reasonable."
"The valuable feature of Google Cloud SQL is its high availability option. The product is stable."
"It performs very well, especially under high load where it automatically scales up the RUs, and the main advantage of Microsoft Azure Cosmos DB is its low latency, with response times in milliseconds, making it great for chatbots."
"The best part of Microsoft Azure Cosmos DB is that with the default configuration and the Azure functional pipeline, if your go-to cloud provider is Microsoft Azure, the whole integration is seamless."
"Our customer is very satisfied with it."
"The scalability and ease of use with the APIs of Microsoft Azure Cosmos DB have allowed us to meet our customers' expectations pretty easily with little barrier to entry."
"The solution is stable."
"The latency and availability of Microsoft Azure Cosmos DB are fantastic."
"The fact that scalability can be achieved by simply configuring availability zones is very attractive."
"Microsoft Azure Cosmos DB is very easy to use once you understand the process, and we have a very good team; because it is more costly compared to other services, the Microsoft product team takes customers very seriously and if any issue arises, they immediately join calls with customers to troubleshoot problems."
 

Cons

"The only room for improvement here is that they need to connect to more existing data sources so that it becomes easier for a layman to get a more realistic understanding of what's happening."
"The overall documentation and the connectors need improvement."
"It is hard to do logging with the solution."
"The customer support should be improved."
"For data analysis, the AI area of the product has certain shortcomings where improvements are required."
"They could improve documentation and dashboard stability for efficient user experience and database management."
"Better integration with other tools could improve this solution."
"The monitoring part could be better."
"Sometimes, the solution's access request takes time, which should be improved."
"I would give a low rating to Microsoft support, as whenever I talked to them, I never got a solution. I had to guide them."
"It is easy to use, but optimization has been a mixed experience. It has been more of trying to figure out how to do so. We have not found much support there, so we have to come up with our own way of optimizing it in different ways. That is one area of improvement."
"A couple features that would help me in architectural solutions would be customizable architecture or customizable documentation, which both Microsoft Azure or Microsoft Teams can provide."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high — and because of the stability issues."
"The main downside I have faced was with hierarchical partitioning in Microsoft Azure Cosmos DB."
"We'd like to avoid full DR replication if possible, as this would result in significant cost savings."
"The solution cannot join two databases like Oracle or SQL Server."
 

Pricing and Cost Advice

"It is not expensive, especially considering the significant reduction in database management time."
"The solution is affordable."
"You need to pay extra costs for backup and replication."
"While the platform’s pricing may be higher, it aligns with industry standards, considering the quality of service and features provided."
"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."
"The pricing is very much an important factor as to why we use this solution."
"From a financial perspective, Google Cloud SQL is on the cheaper side."
"Cosmos DB is a highly cost-optimized solution when used correctly."
"It's expensive. I would rate it a seven out of ten for pricing."
"From a startup point of view, it appears to be expensive. If I were to create my startup, it would not have the pricing appeal compared to the competition, such as Supabase. All those other databases are well-advertised by communities. I know there is a free tier with Azure Cosmos DB. It is just not well advertised."
"Cost isn’t a big hurdle for us right now. The solution is not costly."
"Azure is a pay as you go subscription."
"Cosmos DB is cost-effective when starting but requires careful management."
"The pricing for Microsoft Azure Cosmos DB is good. Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective."
"The pricing and licensing model was initially difficult to understand, but as soon as I learned what was going on and how it was priced, it was pretty easy."
