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.

Real-time messaging has transformed customer updates and now powers responsive AI experiences

The primary benefits of Microsoft Azure Cosmos DB include horizontal scalability. The main advantage is that it handles data growth without requiring database redesign when traffic increases. Low latency access is another key benefit, as read and write operations are very fast, which is extremely helpful for real-time applications. Flexibility is also valuable because Microsoft Azure Cosmos DB uses JSON schema format, which contrasts with traditional table schemas that require time-consuming changes. In modernization scenarios where client requirements change rapidly, Microsoft Azure Cosmos DB offers more flexible schema design. High availability is another important feature, as it is well-suited for business-critical systems. My overall experience using Microsoft Azure Cosmos DB with other Azure services shows that it is more flexible compared to SQL Database and more readable because of its JSON format, making it easy to understand. It is more interactive because viewing the Microsoft Azure Cosmos DB schema clearly shows what is happening in the application and what will be achieved. In contrast, SQL requires writing many queries to obtain details, making Microsoft Azure Cosmos DB more suitable and flexible. My team's experience developing with Microsoft Azure Cosmos DB SDKs and APIs has been very comfortable and easy to implement. We are currently migrating .NET applications to Python-based AI solutions using Copilot, where we performed reverse engineering and are moving to forward engineering. We use APIs to connect with Microsoft Azure Cosmos DB and manage database containers and items, performing CRUD operations such as create, delete, and read operations, and querying JSON. We are using REST APIs with Python-based solutions, with a service layer and Microsoft Azure Cosmos DB integration.

Quotes from Members

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

Pros

"It's all built into the web browser, so any operating system will work."

"Google Cloud SQL is easy to start with and allows me to scale as needed, which is advantageous from a developer perspective."

"It runs really well, it's cheap, it's efficient, it's user-friendly."

"It directly provides robust data safety. It also offers various other storage options, such as Google Cloud Storage. These services ensure data security and redundancy. Furthermore, it includes different storage classes, allowing flexible data management tailored to specific needs."

"The most valuable features are that it's easy to use, simple, and user-friendly."

"Google Cloud SQL enhances our AI-driven projects by providing features like query optimization and scalability for efficiently processing large datasets."

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

"The initial setup is straightforward."

More Google Cloud SQL pros

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

"The solution is user friendly and Microsoft's technical support is good."

"Microsoft Azure Cosmos DB has reduced the database administration for us, reduced our operational cost, and provides an overall good return on our cloud investment."

"The most valuable feature of Azure Cosmos DB is its scalability. That is the biggest reason I use Azure Cosmos DB."

"The solution is scalable, and we intend to increase our usage."

"The connectors, such as the MongoDB connector and the integration with SQL, are incredibly valuable."

"Cosmos is a PaaS, so you don't need to worry about infrastructure and hosting. It has various APIs that allow it to integrate with other solutions. For example, we are using a MongoDB-compatible API for customers, which makes it easier for developers on the team who previously used MongoDB or are accustomed to the old document storage paradigm."

"The biggest benefit it offers is scalability. It's easier to work with concurrency and updating data."

More Microsoft Azure Cosmos DB pros

Cons

"Google Cloud SQL needs to improve its support for high-end I/O operations. On-prem systems with high I/O capabilities perform better, as Google Cloud SQL takes more time to handle the same tasks."

"The overall documentation and the connectors need improvement."

"For data analysis, the AI area of the product has certain shortcomings where improvements are required."

"It is hard to do logging with the solution."

"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."

"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."

"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL. This would enhance the capabilities of Google Cloud SQL."

"The customer support should be improved."

More Google Cloud SQL cons

"It is not as easy to use as DynamoDB."

"I would like to see certain improvements and enhancements in Microsoft Azure Cosmos DB."

"The only area Microsoft Azure Cosmos DB can improve on is its documentation; while it is solid and very useful, enhancements in the indexing documentation would help users save costs and make it more cost-effective."

"Performance issues do not occur frequently, but I occasionally face performance issues with Microsoft Azure Cosmos DB."

"In the long run, there should be an addition of more features, especially because this space is evolving quickly. It all boils down to how many more features you are adding, how many integrations you are supporting, and how many more APIs you have that are standard APIs."

"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."

"One of our biggest pain points is the backup and restore functionality needs improvement."

"One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document."

More Microsoft Azure Cosmos DB cons

Pricing and Cost Advice

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

"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 solution is affordable."

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

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

"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."

"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."

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

"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."

"Its price is very good for the basic stuff. When you go to a more complicated use case, especially when you need replication and availability zones, it gets a little costly."

"Cosmos DB is a managed offering, so its cost is understandably higher."

"If you are a small organization or startup building from scratch without the Microsoft Startup Founder Club support, it could be expensive."

"For the cloud, we don't pay for the license, but for the on-prem versions, we do pay."

"Microsoft provides fair pricing."
