Robust multidimensional database has enabled smooth API integrations and modern data workflows
I think InterSystems IRIS is a continuation of the Caché legacy. Since I have been working with it since 2005 with Caché, I think it is a really amazing tool. It is a very robust and very scalable database. It is very good to work with, and I am already used to working with it. Where it falls a bit short is in the availability of manpower and professionals who work with InterSystems IRIS or Caché. There are few professionals who work with it. Another thing is the cost and the license cost. I think there could be some kind of package that could serve smaller companies and small and medium-sized companies. That would reach a larger slice of the market, because the cost to work with Caché, InterSystems IRIS, and so on is high. I would make this remark about putting together a package and a new product that could serve small and medium-sized companies. The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost. The licensing cost is the main issue I have already mentioned.

Improved multi-cloud data management has simplified operations and supports seamless Kubernetes
From my perspective, the biggest challenge with VMware right now is the pricing. To be very honest, in many cases I find myself recommending alternative solutions instead of VMware. Even if those alternatives come with a bit more complexity, customers are often more willing to accept that than the current VMware pricing model. In the past, VMware used a socket-based licensing model, which was easier for customers to understand and budget for. Now the shift to a core-based licensing model has significantly increased costs for many environments, especially for organizations running modern high-core CPUs. One positive aspect of the new model is that VMware has bundled several components together. For example, earlier when deploying vSphere, customers also had to purchase vCenter separately for management. Now multiple components are packaged into a single SKU, which simplifies some aspects of procurement and deployment. While this consolidation has its benefits, the overall licensing and commercial costs remain very high. Pricing is not the only issue. I believe Broadcom also needs to reconsider its strategy in light of the current market conditions. The approach they are taking may be strategic from a business perspective, but from what I see in the field, it is leading to lost opportunities. Many customers who previously relied on VMware are now actively exploring alternative virtualization platforms. I’m not sure where this direction will ultimately lead, but based on my experience, it is already affecting adoption. Since you’ve been trying to reach me for some time—and we also had a discussion a couple of years ago—I hope this feedback helps Broadcom understand the current sentiment in the market and potentially make adjustments. Another important concern is the way features are bundled. In many cases, customers only need basic virtualization and high availability capabilities. However, the current packaging often includes additional features that they may not need. A good analogy is that if a customer only needs an entry-level car, we shouldn’t be forced to sell them a Rolls-Royce. VMware could benefit from adopting a more modular or à la carte licensing model, where customers can choose only the components they truly require. For example, if a customer only needs core virtualization functionality, they should be able to purchase just that. This would allow partners and solution providers to better align solutions with customer requirements and position VMware more competitively in the market. Another challenge I want to highlight is the pricing model based on U.S. dollars and the way multi-year licensing is handled. In many enterprise and government projects, customers prefer to commit to three-year or five-year licenses and pay the full amount upfront. However, in approximately 20% of the deals I work on, we lose opportunities because VMware only provides dollar-based pricing for the first year. When it comes to the following years, the contract requires renewals annually rather than allowing a fixed multi-year upfront payment. This approach is particularly problematic for government and public sector customers. Many of them are ready and willing to pay for three or five years in advance, but the current VMware model does not support that structure effectively. Because pricing is tied to the U.S. dollar and subject to yearly adjustments, VMware does not lock in pricing for the full term. From a customer’s perspective, this introduces uncertainty and makes procurement more complicated. Ideally, if a price is quoted—for example, $100 per year—it should remain consistent across a multi-year agreement. Customers would be comfortable committing to a five-year term if the price were fixed and predictable. Unfortunately, that flexibility is currently not available across VMware products, whether it is vSphere, VMware Tanzu solutions, or other offerings. For large enterprise environments, one-year commitments are usually not practical. Many enterprise customers prefer longer-term agreements for budgeting and procurement reasons. Even when they are willing to accept the higher cost associated with the core-based licensing model, the lack of a clear multi-year upfront option often becomes a deal-breaker.

"The best features that InterSystems IRIS offers in my opinion are the speed in querying data, and due to our system, which requires a large query with a large volume of data, InterSystems IRIS stands out for its query speed, making my work easier."
"InterSystems IRIS as a database is very efficient, with its best features being its speed and high performance, along with an easy understanding of its data searching functionalities."
"InterSystems IRIS has had a positive impact on my organization by improving performance and data security."
"We chose Greenplum because of the architecture in terms of clustering databases and being able to have, or at least utilize the resources that are sitting on a database."
"The solution can scale."
"It's a very good product for reducing the time and man power needed for database optimization for datawarehousing purposes."
"The most valuable feature for me is that it is open source. The licensing costs are really low and they are transparent."

"It's one of the fastest databases in the market."
"The most valuable feature of Greenplum is the Massively Parallel Processing (MPP)."
"We have a set of workflow flows that takes 10 hours in Oracle Exadata, now it takes 4 hours with EMC Greenplum."
 

Cons

"I cannot determine a very positive impact or a beneficial result from InterSystems IRIS, although this observability part is important because we were able to find problems much faster."
"InterSystems IRIS can be improved since its studio is very poor."
"Python support can be enhanced further, as it's really clunky at the moment, considering that the use of Python is pretty much all over the world and nobody knows ObjectScript really thoroughly and deeply."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"InterSystems IRIS can be improved by addressing the lack of libraries, mainly mathematical ones, where we would save a lot of time on some formulas that we have to build by hand every time we need them."
"The fact GreenPlum is using an older version of Postgres means developers coming from other products will find many missing features in PostgreSQL, features which you would assume are standard."
"The product has to improve the crisis management, especially in memory issues."
"VMware Tanzu Data Solutions is already a strong platform, but it could be improved with better support for a wider range of databases and data services for more flexibility."
"We had deployment issues after installing new patches."
"If you're outside IP address range, the clustering no longer has all the features which is problematic."
"We had a bit of an issue with stability."
"The High Availability feature is not really reliable."
"I would like to see the performance of the administration portal improved and additional messaging protocols."
