High availability and operational efficiency achieved with reliable managed services
We have primarily used Amazon Aurora for handling our databases. We migrated from PostgreSQL to Amazon Aurora about a year ago. It serves as a customized PostgreSQL database that we utilize Amazon Aurora offers a 99.9% SLA compared to PostgreSQL. This ensures a high level of availability for our…

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.

Quotes from Members

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

Pros

"Aurora is a key pillar for us, offering performance and availability."
"They now offer some really good scaling and limitless versions that are available to me, which I find very impressive."
"The migration process to Amazon Aurora is the best part; it's one of its key strengths, as we hardly had any hiccups during migration, which was very smooth and pretty straightforward given our data was mostly in English."
"My overall experience with Amazon Aurora is very positive. I rate it ten out of ten for its reliability and efficiency."
"The solution’s scalability is good since we don’t need to take a maintenance window during unpredictable workloads. I like the solution’s behind-the-scenes happenings. It is a great feature."
"Amazon Aurora is built on community databases and AWS has added additional features to it, allowing customers to have enterprise-level features at a lower cost."
"The provision of custom read and write endpoints eliminates the need for managing a separate proxy load balancer."
"One of the standout features of Amazon Aurora is that we do not need to maintain disaster recovery or manage availability zones."
"So far, we do not have a lot of issues. It's pretty problem-free."
"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"Replication is a valuable feature and easy to use."
"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
"The scalability is very good."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
 

Cons

"Amazon Aurora should upgrade its base PostgreSQL versions more frequently and offer all PostgreSQL extensions."
"The product's distributed query process for MySQL needs improvement."
"In Oracle, tools like Veridata allow for comparing databases and certifying data accuracy, even offering repair capabilities, which are missing in Aurora. There should be a similar comparison tool in Aurora."
"It would have been helpful if they had provided some benchmarking numbers."
"Room for improvement might be in the UI, integrations, or data working capabilities for better user experience."
"There are tuning challenges."
"I would like to see more AI-related features in future releases."
"It is a bit costly. The features are quite good, and I wouldn't say it requires any technical improvements. But from a cost perspective, some clients wouldn't go for Aurora because of that."
"This solution is in need of more current tools."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"The pricing is a bit expensive."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"I would like to see backups from secondary servers."
"I experienced poor input/output (IO) performance."
"The solution really doesn't add new features very often."
"The technical support services need substantial improvement."
 

Pricing and Cost Advice

"The tool’s pricing depends on the instance type. For cost optimization purposes, we use the result instance category."
"I would rate the pricing a six out of ten, with ten being expensive."
"The price could be lower compared to its competitors."
"It is quite expensive."
"It is an expensive solution."
"There is no need to buy a license for the product. We can pay as per the use case."
"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."
"For me, it's always too expensive."
"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
