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

"The performance is okay as long as the volume of queries is not too high."
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
"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."
"DashDB is a good product to work with and the extra cost you spend on performance, technical support and tools to work with is worth it."
"It is stable when there is support from IBM."
"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."
"Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
"Data compression. It was relatively impressive. I think at some point we were getting 4:1 compression if not more."
"For me, as an end-user, everything that I do on the solution is simple, clear, and understandable."
"Those reports were improved from a couple of hours to minutes."
"Parallel data processing is a significant feature for me."
"Distribution concurrency control."
"It has the capacity to handle terabytes of data with query response times that are very low."
"There is minimal on-going maintenance."
"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."
 

Cons

"With dashDB, scalability and uptime need more improvement."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"The support channels need to improve."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"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."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"Db2 is not a solution that I recommend. We have a lot of experience and we are not satisfied with the product or the support that we received."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"Service support costs are high."
"If the demand for clock or disk space grow over the limit, it will be necessary to change the appliance, because it's not possible to upgrade any component of this machine."
"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."
"Technical support has been awful. I found them unwilling to help, and with direct VPN connection to systems, unwilling to actually connect and look at information, which is part of our contract."
"Support for interfaces has been poor."
"Data lineage on column or even object level does not exist, therefore external applications have to be used"
"Concurrency was an issue. If you run small queries it runs well, and the performance is good, however, when you run multiple long queries or multiple joins, it has some concurrency issues."
"In-DB processing with SAS Analytics, since this is supposed to be an analytics server so the expectation is there."
 

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 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."
"Expensive to maintain compared to other solutions."
"The solution has a yearly licensing fee, and users have to pay extra for support."
"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."
"The annual licensing fees are twenty-two percent of the product cost."
