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.

Provides super sharp latency, excellent availability, and the ability to effectively manage costs across different tenants

For integrating Microsoft Azure Cosmos DB with other Azure products or other products, there are a couple of challenges with the current system. Right now, the vectors are stored as floating-point numbers within the NoSQL document, which makes them inefficiently large. This leads to increased storage space requirements, and searching through a vast number of documents in the vector database becomes quite costly in terms of RUs. While the integration works well, the expense associated with it is relatively high. I would really like to see a reduction in costs for their vector search, as it is currently on the expensive side. The areas for improvement in Microsoft Azure Cosmos DB are vector pricing and vector indexing patterns, which are unintuitive and not well described. I would also like to see the parameters of Fleet Spaces made more powerful, as currently, it's somewhat lightweight. I believe they've made those changes intentionally to better understand the cost model. However, we would like to take a more aggressive approach in using it. One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document. Additionally, you must specify the configuration of that vector when you create an instance of Microsoft Azure Cosmos DB. Once the database is set up, you can't change the vector configuration, which is incredibly limiting for experimentation. You want the ability to try different settings and see how they perform, as there are numerous use cases for storing more than one vector in a document. While interoperability within the vector database is acceptable—for example, I can search for vectors—I still desire a richer set of configuration options.

Quotes from Members

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

Pros

"The product is scalable."

"The initial setup is straightforward."

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

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

"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."

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

"The speed is very good, it's useful in terms of the simplicity of doing backups, you can have redundant databases for reports or posts, it's SQL which is easy to learn if you know something about databases, I like the cloud aspect, the pricing of the solution seems reasonable, and the solution is stable."

More Google Cloud SQL pros

"Azure Cosmos DB's graph queries are its most valuable feature. Although I have not yet explored vector search, it's coming to Cosmos DB, and I plan to look into it. Having data in a flat file format in a document database speeds up processes, which is the primary purpose. Additionally, Cosmos DB's use of the Mongo platform makes it intuitive and cost-effective."

"The ability to scale automatically is very valuable."

"Microsoft Azure Cosmos DB is a good solution for distributed application requirements. We can perform multi-modeling."

"It gives us a lot of flexibility. The scaling is instantaneous as well. You immediately have all the resources available."

"Our customer is very satisfied with it."

"The solution is used because we get faster response times with large data sets than with SQL."

"The most valuable feature of Microsoft Azure Cosmos DB is its ability to handle concurrency and consistency."

"It works reasonably fast. You can retain the original format of the document as received by the third-party system."

More Microsoft Azure Cosmos DB pros

Cons

"In the case of Google, they need to work on a more easy interface for users."

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

"Google Cloud SQL still needs better connectivity to outside, existing data sources."

"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."

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

"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 most challenging part is dealing with legacy data from your old systems and migrating it into the new setup, but once you've completed the data migration, it becomes quite convenient to use."

"In the case of Google, they need to work on a more easy interface for users."

More Google Cloud SQL cons

"At this stage, we would like more enterprise support. We use MongoDB a lot, and we're trying to get rid of MongoDB, so I would like to see more features in the Cosmos DB API for MongoDB space."

"The challenge for us is always scale."

"I do not have any specific suggestions for improvements at the moment. However, having more AI capabilities in the future would be beneficial."

"The size of the continuation token in Azure Cosmos DB should be static rather than increasing with more data, as it can lead to application crashes. They should use a static key size."

"Our use case was a failure with Microsoft Azure Cosmos DB, and we do not have any other opportunity to use Microsoft Azure Cosmos DB."

"I would like the speed of transferring data to be improved."

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

"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."

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."

"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."

"The solution is affordable."

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

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

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

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

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

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

"There is a licensing fee."

"Our experience with the pricing and setup cost is that it aligns with what we expect based on the pricing we see. However, I would absolutely like it to be less if possible."

"Cosmos DB is expensive compared to any virtual machine based on conventional RDBMS like MySQL or PostgreSQL."

"Its price is in the middle, neither too low nor too high."

"The solution is very expensive."
