Tech Lead at Impetus

The ability to create a lot of views or materialized views is beneficial

Improvement in the immediate response and the process of getting into a call could be helpful. We have had to wait for at least twenty-four hours to get a call and then wait for a couple more hours for a solution. Improved connectivity to different BI tools and already published connectors for major tools in AWS could enhance the service.

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

"The initial setup of this solution is straightforward."

"The most valuable features of Amazon Redshift include everything being integrated within Amazon, making it really easy to run queries faster, allowing us to retrieve data as soon as possible compared to other tools."

"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."

"The solution is scalable. It handles different loads very well."

"The valuable features are performance, data compression, and scalability."

"It is quite simple to use and there are no issues with creating the tables."

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

"Amazon Redshift offers a relatively flexible structure...I rate the technical support a nine out of ten."

More Amazon Redshift pros

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

"The solution is stable."

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

"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."

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

"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."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

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

More IBM Db2 Warehouse pros

Cons

"There might be some limitations from a business intelligence perspective, but nothing we can't find a workaround for."

"The solution could improve in handling more data formats and more native support for RDF."

"This solution lacks integration with non-AWS sources."

"Amazon Redshift is a little more expensive than other products."

"If you require a highly scalable solution, I would not recommend Amazon Redshift."

"Should be made available across zones, like other Multi-AZ solutions."

"Improvement in the immediate response and the process of getting into a call could be helpful."

"Amazon should provide more cloud-native tools that can integrate with Redshift like Microsoft's development tools for Azure."

More Amazon Redshift cons

"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."

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

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

"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."

"IBM Db2 Warehouse needs to improve its interface."

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

"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."

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

More IBM Db2 Warehouse cons

Pricing and Cost Advice

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

"The cost must be improved."

"The pricing is reasonable."

"The solution has very competitive pricing."

"The product is quite expensive."

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

"At the moment, pricing is a little bit on the higher side, although it depends on the size of the company."

"The solution is available at a mid-range price compared to other vendors."

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).
