Senior Chief Engineer (Enterprise System Presales/Postsales) at a tech vendor with 10,001+ employees

Has simplified ETL workflows with on-demand processing but needs improved cost efficiency and visibility

I have used AWS Glue with S3 for making tables and databases, but regarding Amazon EMR, I do not remember much as we are currently using it very minimally. This is my observation: In EKS, we have had to deploy by ourselves because EKS does not provide the Hadoop framework, Spark, Hive, and everything, but we have completed all the deployment ourselves. Whereas Amazon EMR provides all these things. The cost factor differs significantly. When you run Spark application on EKS, you run at the pod level, so you can control the compute cost. But in Amazon EMR, when you have to run one application, you have to launch the entire EC2. In Qubole, the interface was very good. I could see many details because in Amazon EMR console, very few details are available. In Qubole, at one link, you can get all the details of what is happening, how the processes are running, and the cost decreased by using Qubole. I found Qubole more user-friendly and cost-effective. From the security point of view, we had to open some access rights to Qubole, which might be a drawback in comparison to Amazon EMR which is native to AWS.

Advanced features enhance business intelligence, but complex management calls for improved user guidance

While my experience with IBM Db2 Warehouse is somewhat limited, when compared to other databases such as Oracle, there are areas for improvement. They need to enhance the database to make it more user-friendly and easier to master. They should implement a more comprehensive graphical user interface with additional features. For instance, when users encounter problems, the system should provide better guidelines and troubleshooting directions, except for hardware-related issues. They need to implement tools that would help users perform basic troubleshooting rather than solely relying on support. Other databases have features where users can investigate specific issues using error codes. From my experience, many minor issues could be resolved before escalating to support.

Quotes from Members

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

Pros

"Amazon EMR is a good solution that can be used to manage big data."

"It's made life very easy."

"The initial setup is straightforward."

"It's helped to automate processes."

"In Amazon EMR it is easy to rebuild anything, easy to upgrade and has good fault tolerance."

"Less expensive than in-house hosting, much more scalable when needed to process larger volumes of data."

"The initial setup is pretty straightforward."

"Amazon makes it about as easy as it can be to dip a toe in those waters."

More Amazon EMR pros

"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."

"If you have good people designing how the data is stored, it's a marvelous tool."

"The solution is stable."

"The most valuable features of IBM Db2 Warehouse include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support."

"The analytics engine is not bad at forecasting predictions."

More IBM Db2 Warehouse pros

Cons

"In general, I would rate the solution at a four out of ten."

"The solution can become expensive if you are not careful."

"Better monitoring, debugging, and stability are all needed."

"Modules and strategies should be better handled and notified early in advance."

"Amazon EMR can improve by adding some features, such as megastore services and HiveServer2. Additionally, the user interface could be better, similar to what Apache service provides, cross-platform services."

"One of the lacking features is good web support."

"The initial setup was time-consuming, and deployment took approximately 30 minutes."

"Whenever we have scaling policies for load balancing and our load increases the input rate, we increase the resources. However, at that time Amazon AWS is not providing the scale of the required resources in a short time."

More Amazon EMR cons

"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."

"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."

"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."

"It takes a long time to have a new version or release, similar to Oracle."

"There should be more material available for training and training should be free."

"In terms of improvement, IBM Db2 Warehouse should be more scalable."

"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."

"Lacks sufficient documentation and particularly in Spanish."

More IBM Db2 Warehouse cons

Pricing and Cost Advice

"Amazon EMR's price is reasonable."

"The price of the solution is expensive."

"Amazon EMR is not very expensive."

"The cost of Amazon EMR is very high."

"You don't need to pay for licensing on a yearly or monthly basis, you only pay for what you use, in terms of underlying instances."

"The product is not cheap, but it is not expensive."

"There is a small fee for the EMR system, but major cost components are the underlying infrastructure resources which we actually use."

"There is no need to pay extra for third-party software."

More Amazon EMR pricing and cost advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."
