Find out how to create per-VM Value Fashions for per-GB-VRAM Options


This month at VMware Discover Europe in Barcelona, we hosted an Government Briefing session for VCPP companions. It included a number of breakout classes, and I used to be invited to current the one titled “Exploiting your VCPP Bundles to the fullest with incremental income streams”. In essence, my breakout session lined methods to construct further, monetizable companies utilizing the VCPP Flex-Core Bundle and Add-Ons.

Through the session, one of many attendees requested an fascinating query, that comes up in lots of conversations with companions: “How do I arrive at an affordable pricing mannequin for per-GB-VRAM options and merchandise in VCPP?”. That is what I’m going to reply on this weblog submit.

Understanding VCPP Pricing

If you look into the Product Utilization Information, positioned in Associate Join, you’ll discover that almost all of merchandise and options are metered and priced based mostly on the quantity of VRAM consumed by the VM that leverages a given set of options. For instance, NSX-T DC Skilled provides x Factors to the Flex Core Bundle cost, whereas the NSX-T DC Superior Version provides y Factors to it. The extra options and merchandise a given VM makes use of, the costlier it turns into for the supplier – in direct relation to the GB of digital RAM reserved or allotted to that specific VM.

This mannequin gives a properly aligned foundation for calculating the complete value of any given workload and is absolutely Pay-as-you-go and scalable for the supplier. On the gross sales and pricing aspect, nonetheless, the per-GB-VRAM metric could cause a problem. It’s pretty unusual within the cloud market to cost for options, like community capabilities in NSX or monitoring capabilities in vRealize, based mostly on the quantity of VRAM a VM has. Clients could be reluctant to pay a distinct worth for his or her distributed firewall or OS monitoring between two VMs, solely as a result of they’ve completely different sizes of reminiscence. There’s merely no relatable technical connection between the characteristic and the completely different worth factors.

Aligning on a per VM cost

The apparent reply to the above query is due to this fact: Cost per characteristic set that any given VM makes use of, regardless of the quantity of VRAM the VM has. This often raises some eyebrows with the viewers. Why? As a result of this proposal disconnects the fee driver (VRAM) from the income driver (No. of VMs). And that may make calculations difficult and enhance threat on the specified margins.

Nonetheless, with the best knowledge and a few easy monetary engineering, VMware Cloud Suppliers can mitigate this threat and make sure the margins they need. Each whereas promoting options and merchandise on a compelling, per-VM foundation.

It’s all concerning the Math

Right here is the way it’s accomplished: We to begin with want a stable understanding of the common VRAM dimension and distribution of VMs {that a} single buyer or the sum of all clients are operating on the cloud platform that we wish to calculate pricing for. Whether or not the evaluation is finished for one buyer solely or throughout all clients is dependent upon whether or not the supplier has a devoted pricelist per buyer or a single pricing mannequin throughout all clients. Total, the bigger the set of VMs we have a look at, the higher to reduce threat.

As a straightforward instance, lets assume the record of VMs seems to be as follows:

VM vRAM (GB)
VM-1 4
VM-2 4
VM-3 2
VM-4 8
VM-5 24
Desk 1: Instance Checklist of VMs

Because the value driver for the supplier within the VCPP mannequin is GB of VRAM in relation to the factors per GB VMware prices per set of options, we have to perceive the incremental variety of factors. You possibly can seek advice from the Product Utilization Information to calculate the variety of factors based mostly on the options and merchandise your clients want. Let’s assume the supplier needs to cost and promote a set of options that provides 5 factors per GB of VRAM to the Flex-Core worth. This offers us the next:

VM vRAM (GB) Added Factors
VM-1 4 20
VM-2 4 20
VM-3 2 10
VM-4 8 40
VM-5 24 120
Desk 2: Instance added Factors per VM

And based mostly on the VCPP factors worth, the supplier can now calculate the incremental value for any given VM dimension. We assume the record worth of 1 USD per VCPP level right here. To this point really easy. Now comes the essential half. We wish to discover a worth in direction of the client that fulfils the next necessities:

  • Be relevant throughout any given GB VRAM dimension of a VM
  • Scale back Danger
  • Protect Margin
  • Be aggressive

To attain this steadiness, we first must calculate the common value added for the characteristic set. On this case, it’s 42 USD:

VM vRAM (GB) Added Factors Added Prices
VM-1 4 20 20 USD
VM-2 4 20 20 USD
VM-3 2 10 10 USD
VM-4 8 40 40 USD
VM-5 24 120 120 USD
  Common Price: 42 USD
Desk 3: Common Prices for the instance VMs

With this data, the supplier can add a markup as share of the whole common prices for the add-on characteristic set to find out an incremental worth per VM. That worth is impartial of the VMs VRAM dimension, which is the primary necessities we had.

Absolutely the margin is, nonetheless, completely different for VMs of various sizes, and should even be detrimental on a per VM foundation. On this instance, VM-5 would generate a detrimental margin based mostly on these assumptions. To scale back threat and protect wishes constructive margin, the supplier can now calculate based mostly on completely different markups for the characteristic set and decide the optimum, absolute margin that additional ensures competitiveness. On this instance we used 25 p.c markup:

VM vRAM (GB) Added Factors Added Prices Value Margin
VM-1 4 20 20 USD 52,5 USD 32,5 USD
VM-2 4 20 20 USD 52,5 USD 32,5 USD
VM-3 2 10 10 USD 52,5 USD 42,5 USD
VM-4 8 40 40 USD 52,5 USD 12,5 USD
VM-5 24 120 120 USD 52,5 USD -67,5 USD
    Common Price: 42 USD Whole Margin: 52,5 USD
Desk 4: Per VM and whole Margin throughout all VMs

It’s essential to look at that, whereas some absolute margins for bigger VMs, like VM-5 on this instance, are detrimental, the whole total margin at all times stays constructive attributable to restoration from smaller cases. On this case, a set of options or capabilities delivered by merchandise which can be charged at a further 5 VCPP Factors, could be offered at 52,50 USD per VM. This equals a complete of 262,50 USD of incremental income with a complete of 52,50 USD or 20 p.c total margin.

If extra granularity and extra risk-mitigation is required, companions can phase the projected sizes of VMs and apply completely different costs based mostly on the weighted common for per-VM options in these segments. This segmentation might usually be accomplished based mostly solely on VRAM dimension, which leads us again into the unique route of a hyperlink between technically disconnected options to promote and the completely different worth factors. Subsequently, is should be used with warning, i.e. solely in few segments.

An identical strategy is to mannequin VM lessons and worth these VM lessons and their add-ons in line with their use-case. That is incessantly seen in hyperscale pricing fashions and may be accomplished in VCD utilizing Compute Insurance policies, too. With this, VMware Cloud Suppliers can construct, for instance, memory-intensive VM lessons and t-shirt sizes, that include a distinct per-VM add-on worth in comparison with general-purpose VM lessons.

As a remaining choice, Suppliers can embrace the extra options within the base VM worth for a category, for instance a high-security VM class, that features further networking, safety and monitoring capabilities within the per-VM base worth with out Add-Ons.

Further Concerns and Planning

With the above instance, we have been capable of present methods to calculate a per-VM worth from a per-GB-VRAM value driver. The logic introduced therein doesn’t change whether or not the calculation is finished for five, 50 or 5,000 VMs. But there are a few further concerns for real-world eventualities.

To start with, incremental cost inside VCPP is capped at a specific amount of chargeable GB of VRAM. Each VM that’s bigger than that cap, should be handled as if it has the capped most of GB VRAM within the calculation. If that’s not accomplished, the supplier is liable to being much less aggressive and overpricing.

The larger concern that comes up in conversations about this strategy, is the static nature of the mannequin. We checked out a snapshot of VMs and their VRAM sizes at a given time limit. This strategy contradicts the scalable and versatile nature of utilizing Cloud assets, the place VMs get spun up, scaled or deleted as calls for change. To counter this impact and its probably detrimental impression on margin, companions ought to calculate based mostly on completely different eventualities and assumptions concerning the improvement of the setting. Because the setting grows or the calculation is finished throughout a bigger set of VMs, outliers in both route can have much less impression on the margin.

In addition to this fundamental monetary engineering, companions can implement contractual security nets that permit them to regulate pricing in accordance with the common dimension of workloads or different adjustments to the setting, which is frequent follow in cloud environments.

In some circumstances, it will possibly make sense to have sure options included in an elevated base VM worth with out breaking them out into separate, per-VM SKUs. That is for instance the case when a characteristic is often utilized by each VM within the setting, like IDS in NSX-T DC Superior. The identical mannequin could also be utilized for options and functionalities that aren’t detected on a per VM-basis by Utilization Meter. Examples embrace IPv6 dynamic routing, EVPN and VRF, that are detected per Tier-0 Router. Or L2VPN, which is detected on a per-Section foundation. On this case, companions might nonetheless implement a extra granular charging mannequin, however want to concentrate to the inherit threat of disconnecting the fee driver from the income driver. Because of this and to create a predictable pricing mannequin for purchasers, an elevated base cost for all VMs stands out as the better option in comparison with granular per-VM pricing.

Companions ought to seek the advice of the Utilization Meter Detection information, obtainable in Associate Join, to know the precise metering mechanism and derive the suitable charging mannequin.
