High availability and geographical redundancy ensure reliable performance and cost efficiency

Amazon Aurora ( /products/amazon-aurora-reviews ) provides up to fifteen to sixteen read replicas. It replicates data across multiple Availability Zones, ensuring high availability and geographical redundancy, which can be considered a GR instead of a DR. As a managed service, maintenance tasks like backup and restore are handled by AWS ( /products/amazon-aws-reviews ), saving my organization significant time and money. Additionally, its fast cloning feature allows us to create a new clone from a large database swiftly, similar to a zero-copy cloning feature in Snowflake ( /products/snowflake-reviews ). This makes Amazon Aurora a compelling choice for my organization.

Quotes from Members

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

Pros

"One of the standout features of Amazon Aurora is that we do not need to maintain disaster recovery or manage availability zones."

"Amazon Aurora stands out for its ease of use in a managed environment, inbuilt security, continuous backups, numerous read replicas, multi-region automated replication, and seamless integration with other AWS services."

"My overall experience with Amazon Aurora is very positive. I rate it ten out of ten for its reliability and efficiency."

"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."

"We had better control over the parameters that we could tweak in terms of intermediate storage and better indexing capabilities."

"The most valuable feature is the ability to do multiple-read and single-write. These are the kinds of features that we were interested in, and Aurora takes care of that natively."

More Amazon Aurora pros

"The stability is incredible. I have customers with uptimes of several years."

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

"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 initial setup is pretty easy."

"The solution's stability, performance, enhanced functionality, and replication are all great features."

"So far, we do not have a lot of issues. It's pretty problem-free."

More IBM Informix pros

Cons

"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."

"One of the most valuable features is storage scaling."

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

"A challenge I noticed is during migration from PostgreSQL RDS to Amazon Aurora. There are technical challenges, such as the inability to provision the database using a PostgreSQL snapshot directly."

"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."

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

"Amazon Aurora should upgrade its base PostgreSQL versions more frequently and offer all PostgreSQL extensions."

"The pricing could improve. It should be reduced."

More Amazon Aurora cons

"The solution really doesn't add new features very often."

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

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

"The solution lacks some functionality."

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."

"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."

"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."

More IBM Informix cons

Pricing and Cost Advice

"The tool’s pricing depends on the instance type. For cost optimization purposes, we use the result instance category."

"It is an expensive solution."

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

"I would rate the pricing a six out of ten, with ten being expensive."

"It is quite expensive."

"There is no need to buy a license for the product. We can pay as per the use case."

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

"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 am not aware of the licensing costs or terms."

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