Valuable Features

IBM Db2 Warehouse on Cloud offers high-performance columnar storage with advanced compression techniques, enabling efficient data processing without decompression. The integration with IBM Bluemix provides universal access, enhancing collaboration across geolocations. It supports both SMP and MPP instances, ideal for handling large data volumes. Key features include integrated RStudio and a web-based management console. Users appreciate the ease of migration from Netezza and the availability of DB2's features without hardware maintenance.
  • "Ease of migration from Netezza DB; IBM ported over all Netezza's functionality and made the warehouse DB/dashDB the best of breed of the two."
  • "Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
  • "I like that the dashDB solution is built on DB2 technology, which means that you can use all the features of a DB2 database while outsourcing all the hardware and software maintenance."

Room for Improvement

IBM Db2 Warehouse on Cloud requires improvements in scalability and uptime, missing auto-scaling, and pay-as-you-go options. Backup and authentication need enhancements with more retained backup days and AD namespace login integration. Support channels and documentation are lacking, and there are issues with VMware 6.0 and backup/recovery. Users experience challenges in scaling, causing availability issues. Limitations exist in adding data files to table spaces, and regional support needs advancement.
  • "Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
  • "The support channels need to improve."
  • "I would like to see improvements in backup and authentication. It needs the ability to increase the number of retained backups to more than 2 days."

Pricing

Enterprise buyers evaluating IBM Db2 Warehouse on Cloud should consider researching pricing and licensing options thoroughly, as users suggest that the cost is competitive relative to other providers, especially when leveraging compression in a 1TB dedicated environment. They advise assessing growth potential and comparing with similar platforms, especially if integrating IBM's ecosystem. Opting for cloud or Sailfish versions could streamline support and contracts for those focusing on IBM tools and analytics.
  • "If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."

Service and Support

Customer support for IBM Db2 Warehouse on Cloud varies in quality. Some users experience efficient, responsive assistance, particularly for dedicated instances, while others report prolonged ticket durations and recurring challenges. Regional differences exist, with American regions providing more consistent support. Users find the support knowledgeable yet occasionally lacking in delivering timely resolutions, with ratings around average to above average. Some express dissatisfaction due to stretched resolution cycles and reliance on temporary fixes.

Deployment

Users experience a straightforward initial setup for IBM Db2 Warehouse on Cloud. Instances are operational within minutes, and experts facilitate setups in a couple of days. Clearing licensing issues requires assistance, but resources are easily accessible. Some mention challenges with ESX VMware 6.0, indicating areas needing improvement, while others highlight swift deployment timelines lasting months.

Scalability

IBM Db2 Warehouse on Cloud exhibits mixed experiences regarding scalability. Some users encounter no issues, appreciating how it accommodates varying needs, especially for those upgrading from Netezza boxes. However, others face challenges, finding the process to scale, such as adding nodes with downtime, less transparent. While some rate it as highly scalable, others report problems with larger traffic volumes impacting performance. Several clients start with smaller capacities without immediate need for expansion.

Stability

Some users experienced initial stability issues with IBM Db2 Warehouse on Cloud, often due to configuration or licensing misunderstandings, but these were resolved with IBM support. Many moved to dedicated instances for improved service, resulting in 99.9% uptime. While containers sometimes had corruption issues, users noted significant stability when supported by IBM, particularly in regions like North America, rating stability nine out of ten due to available 24/7 assistance.
