Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.
Prabir Kumar Kundu - PeerSpot reviewer

Offers robust security and availability with impressive replication capabilities
Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Quotes from Members

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

Pros

"Replication is a valuable feature and easy to use."
"IBM Informix benefits users with high availability and good integration capabilities."
"So far, we do not have a lot of issues. It's pretty problem-free."
"Every version is faster than the previous."
"The initial setup is very simple."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"OLTP processing capacity and the availability of information with high availability implementation have been significantly improved."
"The solution has been very easy to scale so far."
"I like the JSON stuff."
"MySQL is open-source, easy to use, highly scalable, and supported by a huge community and multiple vendors, making it a reliable choice for everything from financial and PCI data to large-scale relational applications."
"Overall, this is a boon to small to medium database applications."
"The solution is stable."
"It's a mature solution that's been around for decades."
"Like other databases, it has a rich set of functions, such as stored procedures and its own procedural language, which is akin to Oracle SQL. It also has trigger and cursor commands you would expect with a good database language."
"​We use MySQL for enterprise data storage as well as part of the back-end of websites and web applications.​"
 

Cons

"This product could be made easier to use for beginners."
"The solution really doesn't add new features very often."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"I would like to see backups from secondary servers."
"The solution lacks some functionality."
"The solution doesn't include functionality like data anonymization."
"The product needs a lot more marketing involvement from IBM."
"I really would love to have a QT plugin."
"They should come up with a better solution than the NDB cluster for better scaling."
"When it comes to supporting big data, there is space to improve upon the database engines that are supported by MySQL."
"I think that the stored procedures and the development tools to write and debug large queries could be improved."
"MySQL doesn't have the auto-clustering and database clustering features that other competitors provide. They can include these features."
"It would be helpful if there were a graphical user interface to administer, configure, and tune it."
"Documentation is definitely required when running multiple databases on a cluster system."
"We want high availability and replication features, which are currently missing in this solution."
"At times, the autoscaling does not happen when there is a surge in load."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"I am not aware of the licensing costs or terms."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"I use the open-source free community version."
"This is an open-source product that can be used free of charge."
"The tool is open source."
"MySQL Enterprise Support is not cheap, though might still be cheaper than Oracle or SQL Server. They may not have local support depending on where you’re based, but there are many smaller agencies out there that will readily provide support. You’ll need to spend some time looking around."
"MySQL is a free and open-source solution."
"This product has a good price point."
"Can range from free to quite expensive, depending on the environments and requirements, so better to really set goals ahead of setting it up."
"It's cheaper than other solutions."
