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 way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"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."
"It is stable when there is support from IBM."
"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."
"Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
"It will be MPP, so performance should improve."
"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."
"I would recommend this product; it is great and resolves a lot of problems."
"This is a great product; it is lightweight, supports cloud native applications, is easy to implement, is easily manageable, and has excellent support."
"The previous data warehouse was built in Oracle, and one of the things which has improved in GreenPlum is that we can query millions of rows at speed, without creating lags."
"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."
"Very fast for query processing."
"The product's reliability is the most valuable feature."
"The loading speed is very good."
"The most valuable feature is asynchronous calls, which are easy to configure."
 

Cons

"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"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."
"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."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"I would rate the level of dashDB support 3.5/5. While they are very knowledgeable in many areas, you can still struggle to get the correct resolution."
"The support channels need to improve."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"If it had a failure queue with robust delivery and recovery built-in with the same power, that would be great."
"The installation is difficult and should be made easier."
"It needs a much more robust and user friendly monitoring and management front-end tool."
"Initial setup is a little complex. It took around two weeks to deploy."
"The product has to improve the crisis management, especially in memory issues."
"The debugging capabilities and testing flexibilities need to be improved."
"We found some issues with larger tables that have daily data appended, where after a while this seems to create lag in the query speed."
"The initial setup is somewhat complex and the out-of-the-box configuration requires optimization."
 

Pricing and Cost Advice

"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
"Pricing is good compared to other products. It's fine."
"The product is available for free use since it is an open-source technology."
"Since the tool is an open-source product, there is no need to pay anything."
"We are using the open-source version of this solution."
"It is an open-source platform. Although, we have to pay for additional features."
"are using the open-source version, which can be used free of cost."
"The pricing is okay."
"It’s an open-source solution."
