Enhancing analytics with seamless data dumping and reliable support
Our primary use case is data storage and analytics The organization has decided to purchase a full stack solution from IBM due to positive responses, which helped them upgrade from the previous version. The data dumping into the raw zone and the feature of BigQuery is quite attractive. There…

Parallel data processing streamlines operations while cost and cloud integration challenge adoption
The cost of the solution is on the more expensive side, which is a concern for me. Additionally, its promotion and interaction with cloud applications are limited. The cloud version is only available in AWS, and in the Middle East, it is not well-developed in the Azure environment. For the cost to be reduced, it should match competitors. Many features need to be incorporated on the cloud.

Quotes from Members

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

Pros

"Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
"It will be MPP, so performance should improve."
"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."
"The performance is okay as long as the volume of queries is not too high."
"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."
"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
"It is stable when there is support from IBM."
"ARULES() function is the fastest implementation of the associations algorithm (a priori or tree) I have worked with, and in comparison with the R associations package, it is +1000x faster."
"We now have a single store of critical business metrics in the investment bank."
"The underlying hardware that IBM provides with this appliance is made for a specific purpose, to serve performance on a large amount of data, and to do analytics as well. It is faster, when you compare it to any other product."
"Query and process response times have improved resulting in customers being able to process and analyse more in less time."
"Netezza is an easy-to-use data warehouse appliance; it's extremely fast with a low cost and the customers run their BI and advanced analytics in a very flexible manner."
"Simplified development process with less administration."
"The ability to support a lot of complex queries to analyze rather big data sets at the same time is a valuable feature for us."
"Our BI enviroment with Netezza, Cognos and Data Stage has been a great success"
 

Cons

"With dashDB, scalability and uptime need more improvement."
"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."
"I would rate the level of dashDB support 3.5/5. While they are very knowledgeable in many areas, you can still struggle to get the correct resolution."
"The support channels need to improve."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"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."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"We tried to install a newer version of NZA not supported by the version of Netezza we had and it did not work."
"I'm not sure of IBM's roadmap currently, as the solution is coming up on its end of life."
"In terms of features that I would like to see, one is the ability to actually scale out an architecture. Right now, if you buy one, it's fixed. There is no scale-up availability at all."
"Netezza does not scale like other databases, so it cannot run several queries at once."
"Disaster recovery support. Because it was an appliance, and if you wanted to support disaster recovery, you needed to buy two."
"It’s a good product for analytical processing, but they need to conduct more seminars and hands-on training and events."
"Data lineage on column or even object level does not exist, therefore external applications have to be used"
"The most valuable features of this solution are robustness and support."
 

Pricing and Cost Advice

"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
"Netezza is a costly solution. It does serve a specific purpose but it's costlier than what's available in the market, if you go to the cloud."
"The annual licensing fees are twenty-two percent of the product cost."
"Expensive to maintain compared to other solutions."
"The solution has a yearly licensing fee, and users have to pay extra for support."
"The pricing is very expensive. It has a lot CPUs with a lot of components in it. It also has built-in redundancy for resiliency reasons."
"For me, mainly, it reduces my costs. It's not only the appliance cost. There are also support costs and a maintenance costs. It does reduce the costs very drastically."
