Easy to use, stable, has a good interface, and the security is good
I don't know if it's because of experience, but for me, it was easy to install. It's just a matter of having an RPM, then click next, next, and next again. The difficult part comes in when you have to configure the security. That is the most difficult part, but it's not that difficult. It takes less than two hours to install. Two hours max, because I did one yesterday. I installed it on AWS and it was easy to install the software. It was less than an hour for the bare minimum installation. Setting up the security, took close to two hours.

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.

Quotes from Members

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

Pros

"The stability has been good."
"I'm an administrator, and what I like most is the interface, the security, and the storage."
"I am happy with the product, other than pricing I don't have any other improvements that I can suggest."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."
"It's allowed us to do a lot of data analytics with it that we weren't able to do before."
"The most valuable feature is asynchronous calls, which are easy to configure."
"Before we had Oracle Exadata, some queries would take more than 20 hours of execution, and with Greenplum, it takes a few minutes."
"Scalability is simple because it's an MPP database; if you need more processing power or you need more storage, you just add a few more nodes in the cluster, and it works on common commodity hardware, so you can use any type of server without needing proprietary hardware, making it fairly flexible."
"It works very well with large database queries."
"Legacy queuing systems have been replaced by RabbitMQ."
"It's super easy to deploy and it also supports different languages and analytics."
"The security is great, and apart from needing to rely on the developer community for support, I think it's fairly secured, quite robust, and stable so far."
 

Cons

"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
"The pricing needs to be improved."
"In the next release, I would like to see the GUI allow you to configure the security section."
"The product's interface needs improvement."
"I was struggling with installing a few things. It would be good if was somewhat similar to RedHat. There should be more documentation regarding installation troubleshooting."
"One of the disadvantages, not a disadvantage with the product itself, but overall, is the expertise in the marketplace. It's not easy to find a Greenplum administrator in the market, compared to other products such as Oracle."
"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."
"We had a bit of an issue with stability."
"The implementation of an upgrade takes a long time."
"They should add more analytics. Their documentation could also be improved so that I don't have to bother my co-workers and tech support so often."
"If you're outside IP address range, the clustering no longer has all the features which is problematic."
"The documentation needs to be improved. There's a learning curve on setting it up and there are issues arising from slower networks that they lack documentation on."
 

Pricing and Cost Advice

"The platform is averagely priced."
"The pricing needs to be improved."
"Tanzu Greenplum's pricing is really competitive and gives excellent value for money."
"The price is pretty good."
"It is an open-source product."
"This is an open source solution."
"It is the best product with best fit for price/performance customer objectives."
"The solution's pricing is cost-effective as it does not involve significant expenses. Licensing is required only for the server, while clients do not need any licensing. Therefore, it proves to be a cost-efficient option."
"We are using the open-source version of this solution."
"It’s an open-source solution."
