Scalability and the online maintainability of definitions are definite advantages for us
We've had it for so long, so it's status quo. But we've added all sorts of functionality to our applications and there are no issues with databases. Anything developers request, we're able to accomplish. Also, we deal a lot with government regulation - and not to talk about what the company does - but anything that they require of us, because we transmit data back and forth with them, we're able to do that with no problems. And there have been a lot of changes over the past five years that our government dictated regarding what we actually end up doing. So, we're able to be extremely flexible with that.

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.

Pros

"Nowadays, CA is doing a lot of improving as far as online maintainability of definitions, which is a huge improvement over the past. I'm able to do a lot of changes without any outage."
"It definitely ​cuts down on our support costs. I do not get woken up in the middle of the night very often for a problem with Datacom."
"Scalability is definitely one thing. The size of the database can grow without any issues. We've got one database table that's got over a billion rows in it; quite a bit of data, and it handles access like a champ."
"It is a solid product."
"It does its job very well."
"They provide the best support compared to other providers I have used previously."
"They are very responsive; they are always ready to meet any questions that we have or any needs that we have, and we get very personal one-on-one support when we need it with just top-notch service."
"The initial setup is fairly straightforward for a mainframe product."
"This is a great product; it is lightweight, supports cloud native applications, is easy to implement, is easily manageable, and has excellent support."
"I would definitely recommend VMware Tanzu Greenplum; it's open-source and the support is great, and it's also relatively cheap compared to similar solutions."
"We evaluated a variety of message products and found that for the feature set RabbitMQ was the best."
"VMware Tanzu Data Solutions has positively impacted my organization by improving workflow, optimizing costs, and facilitating quick learning, making my team happy about this solution."
"RabbitMQ is good in its real-time capability of delivering the sensor data in different topic abstractions."
"It's super easy to deploy and it also supports different languages and analytics."
"The technical support is exquisite."
"Being MPP which is a bulk operator - we were able to do 1.5 million calculation in 15 minutes."
 

Cons

"I had trouble with an upgrade once but, when I have trouble with the upgrade there's always someone there to support me and get me through it really quickly."
"The only minor issue that we have had with Datacom is in the installation guide: Some of the sizings for the databases have not really worked out for us, so we had to go in and resize them."
"Something that we would like to see is for them to develop integration with open distribution systems."
"There are still some things - and I know they are working on some of them - but for the "no-outage maintainability" of things, they are making improvements as we speak, but there is definitely still room for more of that."
"There are a lot of features that come out with each upgrade, but our application that runs on it has been around for a long time; they sort of decommissioned this application."
"The solution needs improvement on performance."
"It doesn't work as efficiently as we'd like because it requires more segment node capacity (size, RAM, CPU) than we currently have."
"There are some security concerns that have been raised with this product."
"The ongoing response from their support on certain technical issues has been slow. It would help if we can have a faster turn-around here."
"The debugging capabilities and testing flexibilities need to be improved."
"There is need for better stability in the Windows environment."
"VMware RabbitMQ's configuration process could be easier to understand."
"I rate customer service as five out of ten."
