Executive SummaryUpdated on Mar 4, 2025

IBM Informix and Amazon Aurora are competing in the database management system market. Amazon Aurora often seems to have the upper hand due to its comprehensive advanced feature set and scalability, offering a competitive edge in features and ease of deployment.

Features: IBM Informix is noted for its efficient data sharding, spatial data support, and online transaction processing capabilities. Amazon Aurora, by comparison, offers high availability and global reach, thanks to its distributed, fault-tolerant, self-healing storage systems. Its scalability and integration with AWS services are critical advantages, with features such as consistent low-latency replication and seamless integration with other AWS tools.

Room for Improvement: IBM Informix could improve by enhancing cloud-native capabilities and streamlining the deployment process for better cloud integration. It could also benefit from more advanced automation features similar to those seen in rival solutions. Amazon Aurora might focus on reducing costs associated with large-scale operations and offering enhanced data migration tools for users shifting from non-cloud environments. Further refinement of advanced features may also be beneficial to efficient operations.

Ease of Deployment and Customer Service: Amazon Aurora’s cloud-native design facilitates seamless scaling and integration within the AWS ecosystem, supported by extensive documentation and strong customer support. In contrast, IBM Informix, more traditionally an on-premises solution, requires more significant setup effort. Nonetheless, it maintains robust customer support channels.

Pricing and ROI: IBM Informix involves an upfront investment impacting initial ROI, which might be mitigated by its lower long-term maintenance costs. Amazon Aurora, with a pay-as-you-go model, offers potentially lower initial costs and increasing ROI as businesses leverage its scalable nature. The flexible pricing model is seen as economically favorable for scenarios requiring dynamic scaling.

Cloud database has delivered high performance and cost savings for data recovery and growth

Amazon can make better access levels and reduce costs for Amazon Aurora. A cost reduction would support multiple teams to adopt this solution since the cost is currently higher. Comparatively, we have the feature of scaling and everything we need. If you launch PostgreSQL on-premises, you need to have a separate DBA for maintenance and everything. If Amazon reduces the cost of Amazon Aurora, it would support large team adoption. A great feature to see in the next version of Amazon Aurora would be improvements in vectorization. In our PostgreSQL, we have pg_vector that helps with vectorizing many of the tables and that is used for data science projects. If Amazon improves this vectorization, it would be much more useful for data science and AI projects.

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

"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."

"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."

"They now offer some really good scaling and limitless versions that are available to me, which I find very impressive."

"Amazon Aurora's best features are about scaling up and scaling down, which is perfect."

"The main benefits my company receives from Amazon Aurora are performance and cost."

"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."

"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."

More Amazon Aurora pros

"It supports multiple applications and business intelligence tools."

"Not looking at Informix would really mean a shot in your own leg before walking a long distance."

"It supports in-house-built applications in .NET and VB6"

"My advice is to take it; you will never regret it."

"IBM Informix benefits users with high availability and good integration capabilities."

"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."

"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."

More IBM Informix pros

Cons

"While Amazon Aurora meets your current scaling and storage needs, there is room for improvement in cryptography and scalability compared to other databases."

"There is improvement needed to have more developer focus. Additionally, it would be helpful to have a stand-alone solution outside of Amazon. Amazon has a tendency to favor developing web-based clients, which may not always provide the fastest or most responsive solution as desired."

"Room for improvement might be in the UI, integrations, or data working capabilities for better user experience."

"There should be constant changes, which can be challenging to keep up with annually."

"I would like to see more AI-related features in future releases."

"There are tuning challenges. The same methods used for tuning in RDS might not work in Aurora, and some functionalities available in MySQL may not be compatible with Aurora."

"I would like to see performance insights on the database based on the queries. Currently, we use SolarWinds as the monitoring tool. I would like to leverage SolarWinds’ performance insights in AWS services. SolarWinds gives larger insights when we run performance issues."

"The product's distributed query process for MySQL needs improvement."

More Amazon Aurora cons

"There should be more intelligence surrounding discovering data to be able to automatically create indexes."

"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."

"This product could be made easier to use for beginners."

"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."

"The technical support services need substantial improvement."

"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."

"Informix is very sturdy, but the problem for us is the marketing action around Informix."

"The solution doesn't include functionality like data anonymization."

More IBM Informix cons

Pricing and Cost Advice

"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 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."

"It is quite expensive."

"The price could be lower compared to its competitors."

"For me, it's always too expensive."

"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."

"The product has reasonable pricing. We purchase its yearly license."
