Used to support websites and reduces the configuration and maintenance of the database
The solution's initial setup is complex. You have to understand networking when filling out a form to create your RDS. You have to understand a few things. They've made some steps to make it easier, but the person who creates the RDS has to make some irrevocable decisions. They can't be configured afterward. The person who utilizes it has to understand a few things, like networking security and database engines. The solution's deployment has a learning curve, and you have to do it a couple of times to understand exactly what it is and what you want. The deployment is pretty fast and straightforward once you understand the parameters of what you're trying to deploy. Understanding what you're doing probably takes the longest part. If you make any mistakes, you might have to redo it or configure it differently. It's great for those who can afford it. In my business practice, I make sure I can afford a test sandbox so that my mistakes don't impact production. I vet it all out in a different environment before I touch production.

Very scalable with high availability and excellent technical support
The good thing is that there are improvements coming with later function levels for the z/OS Db2. I'd like it if, with the operating system that we've got, z/OS, on the mainframe, it would allow us to refresh the hardware to run Linux dockers on the mainframe. This means this might give us opportunities for different ways of coming into the Db2 environment in the future. We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment. Not only have we got the premium operating systems on OS. We can run LPARs on the same mainframe footprint that is also supporting Linux. This is what has improved and made the mainframe environment more competitive. We're also looking at AI for Db2 as well, and machine learning for the future. We know that AI has come out, that we're going to get that, and we're going to evaluate that product next year for Db2. That said, I haven't got any real complaints about Db2 on the mainframe. For the most part, a lot of the problems we have nowadays are to do with communication between the various teams that you would class as stakeholders.

Quotes from Members

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

Pros

"The product's initial setup phase is simple and straightforward."
"The scalability and cost-effectiveness of AWS were beneficial during spikes in database usage, as it allowed our platform to adjust and remain operational."
"The solution is easy to manage."
"The solution reduces the configuration and maintenance of the database."
"Scalability-wise, I rate the solution a nine out of ten."
"The performance of the solution is valuable."
"The scalability and availability of this solution are the most valuable features."
"The solution's querying feature is most valuable. It allows me to retrieve data quickly."
"Your iOS, your throughputs, your performance cycles, you cannot touch it with Microsoft or with Oracle scalability-wise. That is far and away the most scalable systems and the highest performing systems of the set of them."
"The setup process has become much easier recently."
"We are dealing with millions of transactions a month and the performance is very good."
"The solution is stable."
 

Cons

"If our database is too big, we sometimes face glitches in it."
"The tool should include features to clone the RDS instances and have more central management for a lot of RDSs, not just every instance."
"I find the pricing to be expensive."
"I would like to see some improvements in its version upgrades because its upgrade from MySQL 5.7 to MySQL 8 was not straightforward."
"There are some issues with Db2's database file system not being readable. The storage could also be increased, and the monitoring could be improved."
"The licensing fees can be reduced."
"I would like to see better support for advanced analytics."
"There could be better integration with some cloud solutions."
"The application development requires a Java developer and not every company has these resources."
"Performance is something that can be improved with DB2."
"IBM Db2 Database is not ACID compliant, which would improve it. Db2 lacks Isolation, so when two people are trying to update the same field at the same time it can become stuck. Other newer databases do not have this issue, such as Microsoft SQL, Oracle DB, PostgreSQL, and SAP HANA."
"The command line part of this solution could be much better."
 

Pricing and Cost Advice

"Amazon RDS on Outposts is expensive compared to other solutions."
"The solution can get expensive fast."
"The licenses are included with the subscription my company purchases from Amazon."
"The total cost of the solution depends upon the PVU licensing"
"The solution costs less than other products."
"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."
"Db2 is less expensive than Oracle."
"I rate the price of the IBM Db2 Database an eight out of ten."
"There is a license for this solution and we pay every three years."
"They are competitive and honest (compared to how peer firms approach licensing conversations). ​"

What do you like most about IBM Db2 Database?
Db2 database scalability and performance capabilities match our database needs. It covers pretty much everything a database administrator or engineer might need.
What is your experience regarding pricing and costs for IBM Db2 Database?
IBM Db2 is an expensive solution. While I am not heavily involved with pricing, additional companies provide capabilities or products like those from BMC, which many installations might also purchase.
