Migration to cloud eases management but needs better support for high I/O operations
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. There is also difficulty in changing the time zone after the database is set up. Moreover, some features available in MSSQL on-prem are missing on Google Cloud SQL, affecting migration potential.

Room for improvement in data handling leads to enhanced cost-effective data management performance
It would be beneficial if MongoDB Atlas could better support OLTP aspects and data frames, as well as enhance its capabilities for data pipelines and visualization dashboards. Furthermore, supporting the medallion architecture could be a valuable addition, and incorporating improved spatial and vector handling for geographical data could make it more competitive. Enhancing vector processing for AI capabilities would also be critical.

Quotes from Members

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

Pros

"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 feature for us is the Postgres on Google Cloud SQL since it supports most of the features we need."
"Google Cloud SQL provides complete customization options, along with a dashboarding tool and a comprehensive suite of tools that can be used to customize and build any application needed."
"Google Cloud SQL is very easy to use and easy to set up; it brings the benefits of being simple to perform queries, store data that I needed to store, and extract data when I needed to extract it quite quickly, without having to set up a full database and queries around it."
"My suggestion to anyone thinking about this solution is to jump into it head-first!"
"The deployment model allows for significant control and flexibility."
"Google Cloud SQL is easy to start with and allows me to scale as needed, which is advantageous from a developer perspective."
"Google Cloud SQL is highly scalable."
"The most valuable feature is the schemaless architecture."
"For security reasons, I prefer MongoDB Atlas. It supports role-based access control, so you have an entity for each individual."
"It can store data as a flat file, similar to a file system."
"It enables us to get work done quickly and get to our data."
"Being schemaless is what I like best about MongoDB Atlas."
"It's flexible. We don't need to have a solid upstream availability failover, and everything is seamless in Atlas."
"The product allows us to easily set up and store large amounts of unstructured data."
"I rate MongoDB Atlas a nine out of ten."
 

Cons

"The purging of the data could be better."
"Google Cloud SQL still needs better connectivity to outside, existing data sources."
"The customer support should be improved."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL."
"The only thing that could be better is the pricing."
"It is hard to do logging with the solution."
"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."
"In the case of Google, they need to work on a more easy interface for users."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
"In the past, MongoDB offered more features for free, but now it's quite limited. The free version is limited, and you need to pay extra to fully utilize it. The pricing could be improved."
"The tool's implementation should be made easier."
"The cost needs improvement."
"The cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."
"The UI is not currently designed in a manner to make it possible for a non-technical person or a layman to update the database easily."
"They could explore ways to facilitate deploying MongoDB containers within the platform."
"I would say pricing is an area where MongoDB Atlas could improve."
 

Pricing and Cost Advice

"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."
"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."
"For me, MongoDB is expensive, but I think it is not so expensive for customers."
"The purchasing process through the AWS Marketplace was very good."
"We pay for a license."
"MongoDB Atlas is more cost-effective than Amazon DocumentDB. It also has a pay-as-you-go pricing model. Apart from the standard licensing cost, you must also pay to get MongoDB Atlas technical support, which is expensive."
"The price of MongoDB Atlas is highly affordable."
"It is too expensive. They need to work on this."
"For our service, it was around 300 to 600 euros per month, which was acceptable for our customers."
