Performance optimization and scaling adaptations enable efficient data management
Amazon Redshift does not work alone and requires integration with other AWS tools like S3 and Glue for a complete ecosystem. They should bring the entire ETL data management process into Amazon Redshift. Either they should move Amazon Redshift under Glue, or Glue should be brought under Amazon Redshift. The initial setup could also be improved, particularly in terms of sizing, as it requires trial and error to get right.

Quotes from Members

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

Pros

"The product offers good support for the data lake."
"With the APIs that are available, it can be easily integrated with other tools."
"I am satisfied with the performance of the product."
"I find the most valuable features to be the MPP style of processing, which mostly all of the data warehouses provide. The ability to integrate all other AWS services, such as NSS and S3, with little effort is very helpful. The service is well maintained, there are update patches frequently."
"The tool's most valuable feature is its parallel processing capability. It can handle massive amounts of data, even when pushing hundreds of terabytes, and its scaling capabilities are good."
"The solution is scalable. It handles different loads very well."
"It's very easy to migrate from other databases to Redshift. There are migration tools dedicated for this purpose, enabling migration from other databases like MS SQL directly to Redshift. The majority of the scripts will be automatically transposed."
"I would rate Amazon Redshift a ten on a scale of one to ten."
"The performance is okay as long as the volume of queries is not too high."
"It is stable when there is support from IBM."
"It will be MPP, so performance should improve."
"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
 

Cons

"The OLAP slide and dice features need to be improved."
"It takes a lot of time to ingest and update the data."
"The only minor issue I faced was that it took a bit longer than expected to change the cluster to have more space or storage."
"The initial deployment was complex."
"There are too many limitations with respect to concurrency."
"There might be some limitations from a business intelligence perspective, but nothing we can't find a workaround for."
"One area where Amazon Redshift could improve is in adopting the compute-separate, data-separate architecture, which Delta, Snowflake are adopting, and a few others in the cloud data warehouse spectrum."
"Amazon should provide more cloud-native tools that can integrate with Redshift like Microsoft's development tools for Azure."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"Right now, we are implementing on ESX VMware 6.0. Support for this platform is poor. Also, one of the backup/recovery options is broken and IBM is not addressing the issue."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
 

Pricing and Cost Advice

"The product is quite expensive."
"The cost must be improved."
"The cost is comparable to Snowflake."
"In comparison to the price of similar solutions, Redshift's cost is the lowest."
"Amazon Redshift is an expensive solution. Larger organizations can afford this solution, but smaller businesses would struggle to afford it."
"One of my customers went with Google Big Query over Redshift because it was significantly cheaper for their project."
"It's around $200 US dollars. There are some data transfer costs but it's minimal, around $20."
"Pricing for Amazon Redshift is reasonable, though it could be somewhat higher than other solutions, such as Azure. Still, when you base your comparison on the services offered and the pricing, it's the most reasonable versus its competitors, such as RDS."
"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
