Works as a data warehouse system and collects data from different sources

In terms of improvement, I believe Amazon Redshift could work on reducing its costs, as they tend to increase significantly. Additionally, there are occasional issues with nodes going down, which can be problematic. We often encounter issues like someone dropping a column or changing the order of columns, which can cause synchronization problems when pushing data through our pipeline. It's a minor issue, but it can be annoying.

Quotes from Members

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

Pros

"The most valuable feature of Amazon Redshift is its ability to handle really large sets of data."

"It allows for the storage of huge amounts of data."

"The solution is easy to set up and use."

"Though Amazon Redshift is good, it depends on what kind of business you're trying to do, what type of analytics you need, and how much data you have."

"Setup is easy. It's a fast solution with machine learning features, good integration, and a good API."

"The most valuable feature is the scalability, as it grows according to our needs."

"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."

"You can copy JSON to the column and have it analyzed using simple functions."

More Amazon Redshift pros

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

"Provides good security and reliability."

"It can scale effectively as long as resources are available."

"It can be mounted on the cloud, which is a huge plus. If the client, for example, starts small with on-premise deployment and then it rapidly needs to grow, we can transfer this to the cloud easily."

"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."

"Some of the best features are stored procedures, parallelism, and different indexing strategies."

"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."

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

More IBM Db2 Warehouse pros

Cons

"The product must provide new indexes that support special data structures or data types like TEXT."

"The speed of the solution and its portability needs improvement."

"The high price of the product is an area of concern where improvements are required."

"In the solution, user-based access is quite hard. In general, certain permissions are difficult to manage."

"Pricing needs improvement as the solution is expensive."

"Running parallel queries results in poor performance and this needs to be improved."

"Amazon Redshift could improve the user interface support."

"The solution is unable to work fast."

More Amazon Redshift cons

"IBM Db2 Warehouse needs to improve its interface."

"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 biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."

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

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

"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."

"Lacks sufficient documentation and particularly in Spanish."

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

More IBM Db2 Warehouse cons

Pricing and Cost Advice

"Redshift is very cost effective for a cloud based solution if you need to scale it a lot. For smaller data sizes, I would think about using other products."

"Per hour pricing is helpful to keep the costs of a pilot down, but long-term retention is expensive."

"My customers have implementations that cost about $500 a month for a very small one. I also have a customer with a monthly invoice of about $25,000 USD."

"The price of Amazon Redshift is reasonable because it depends on the usage that you use and for DWH for the long term."

"The cost is comparable to Snowflake."

"This solution implements the pay-as-you-use model, so no license. Pricing could be cheaper."

"The solution has very competitive pricing."

"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."

More Amazon Redshift pricing and cost advice

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

Overview

Amazon Redshift is a fully administered, petabyte-scale cloud-based data warehouse service. Users are able to begin with a minimal amount of gigabytes of data and can easily scale up to a petabyte or more as needed. This will enable them to utilize their own data to develop new intuitions on how to improve business processes and client relations.

Initially, users start to develop a data warehouse by initiating what is called an Amazon Redshift cluster or a set of nodes. Once the cluster has been provisioned, users can seamlessly upload data sets, and then begin to perform data analysis queries. Amazon Redshift delivers super-fast query performance, regardless of size, utilizing the exact SQL-based tools and BI applications that most users are already working with today.

The Amazon Redshift service performs all of the work of setting up, operating, and scaling a data warehouse. These tasks include provisioning capacity, monitoring and backing up the cluster, and applying patches and upgrades to the Amazon Redshift engine.

Amazon Redshift Functionalities

Amazon Redshift has many valuable key functionalities. Some of its most useful functionalities include:

Cluster administration: The Amazon Redshift cluster is a group of nodes that contains a leader node and one (or more) compute node(s). The compute nodes needed are dependent on the data size, amount of queries needed, and the query execution functionality desired.
Cluster snapshots: Snapshots are backups of a cluster from an exact point in time. Amazon Redshift offers two types of snapshots: manual and automated. Amazon will store these snapshots internally in the Amazon Simple Storage Service (Amazon S3) utilizing an SSL connection. Whenever a Snapshot restore is needed, Amazon Redshift will create a new cluster and will import data from the snapshot as directed.
Cluster access: Amazon Redshift provides several intuitive features to help define connectivity rules, encrypt data and connections, and control the overall access of your cluster.
IAM credentials and AWS accounts: The Amazon Redshift cluster is only accessible by the AWS account that created the cluster. This automatically secures the cluster and keeps it safe. Inside the AWS account, users access the AWS Identity and IAM protocol to create additional user accounts and manage permissions, granting specified users the desired access needed to control cluster performance.
Encryption: Users have the option to choose to encrypt the clusters for additional added security once the cluster is provisioned. When encryption is enabled, Amazon Redshift will store all the data in user-created tables in a secure encrypted format. To manage Amazon Redshift encryption keys, users will access AWS Key Management Service (AWS KMS).

Reviews from Real Users
