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

"The solution is easy to use. I am impressed with the tool's features and functionality."

"Google Cloud's user interface is really good, which improves efficiency in my database operations."

"The initial setup is straightforward."

"Google Cloud SQL is highly scalable."

"Ease of management and the ability to oversee the statistics of your SQL."

"This is a stable solution and offers good performance."

"It's SQL. SQL is so easy if you know something about databases. It's easy to learn."

"Its most valuable feature is that it's scalable; I can start off with a base of a lot of data and move as much as I want without a lot of infrastructure changes, so I can run a release model experiment on a thousand people and, if that experiment is a success, run it on a million people without any changes while keeping it much more cost-sensitive for me to do it."

More Google Cloud SQL pros

"Because our complete setup is in Microsoft, we have access to the most premium Microsoft assistance, available 24 hours a day, seven days a week."

"Their new feature, dynamic data masking, is very cool and useful for us."

"The peace of mind that Microsoft Azure Cosmos DB provides regarding global distribution is invaluable."

"It's highly scalable and supports consistency, security, and multiple security options."

"Cosmos is preferred because of its speed, robustness, and utilization. We have all the merchandising information in Cosmos DB, which provides concrete and optimized data when searching for new products on the site. It is faster than other relational databases."

"The ability to scale automatically is very valuable. Additionally, multi-region support automatically synchronizing to a different region for multi-region applications is a cool feature. It's more of a lift with other databases to configure that extra region and set up replication, even if it's on the cloud. With Azure, it's just a button click. It's that simple."

"As a NoSQL database, it offers schema flexibility which simplifies design and reduces initial engineering overhead."

"Azure Cosmos DB helped improve the quality of our search results."

More Microsoft Azure Cosmos DB pros

Cons

"The most vulnerable problem with Google SQL is that while you can customize your access control list, it provides you with a public IP address."

"The purging of the data could be better."

"I would like to see better integration with all the different tools on the platform."

"When discussing media files, such as images and audio files, stored in Google Cloud, concerns about handling large amounts of data arise."

"I am yet to explore a lot of features that are present in this solution. However, it would be good if more documentation is available for this solution. This would help us in preparing for the certification exam and understand it better. Currently, we don't have much documentation. We do the labs for 20 or 25 minutes, but we can't capture and download anything."

"The performance compared to AWS is not as fast, and the technical support could be better as they don't have a dedicated team, but mostly AI handles the support now."

"We see latency issues, so we were forced to introduce an in-memory store."

"The only thing that could be better is the pricing."

More Google Cloud SQL cons

"From a scalability perspective, the key database has to be optimized in a better way that can support auto-scaling architecture or scalability architecture."

"The RUs still appear to be a black box for everyone. Even though they explain read and write RUs, it remains unclear for many users."

"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."

"Slight enhancements in integration interfaces, expanded dashboard functionalities, and broader use-case support would be beneficial."

"In Microsoft manufacturing, managers really need to know about the product."

"A limitation in Azure Cosmos DB is the 2 MB document size. Developers need more systemic support in chaining multiple documents if more than 2 MB is required."

"The tool's pricing is expensive."

"Areas of improvement for Microsoft Azure Cosmos DB include indexing. While it makes data retrieval easier, it also increases costs. If there's a better way to improve indexing at a lower cost, that would be really helpful, but that's the major point for now."

More Microsoft Azure Cosmos DB cons

Pricing and Cost Advice

"While the platform’s pricing may be higher, it aligns with industry standards, considering the quality of service and features provided."

"You need to pay extra costs for backup and replication."

"The solution is affordable."

"From a financial perspective, Google Cloud SQL is on the cheaper side."

"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."

"It is not expensive, especially considering the significant reduction in database management time."

"The pricing is very much an important factor as to why we use this solution."

"It's expensive. I would rate it a seven out of ten for pricing."

"The cost is the biggest limitation of this solution."

"Cost isn’t a big hurdle for us right now. The solution is not costly."

"You need to understand exactly the details of how the pricing works technically to stay within reasonable pricing."

"Cosmos DB gave us three accounts for $400. We pay according to the usage."

"The price of Microsoft Azure Cosmos DB could be a bit lower."

"Because of the lack of understanding about RUs, the costs become unpredictable. It sometimes goes over the budget."

"Cosmos DB is cost-effective when starting but requires careful management."
