Scalable Pricing in a Scalable World

Nati Shalom: Need scalability in the new dynamically-scalable world? Don’t forget pricing

Nati Shalom's GigaSpaces Blog

In most discussions about scalability, we often approach the topic as a pure technical/architecture challenge, and ignore cost issues. The problem is that when we truly scale our application, and want to benefit from economies of scale, we're going to end up with scale limitations, not because of technical issues, but because of the pricing and licensing models.

In most discussions about scalability, we often approach the topic as a pure technical/architecture challenge, and ignore cost issues. The problem is that when we truly scale our application, and want to benefit from economies of scale, we're going to end up with scale limitations, not because of technical issues, but because of the pricing and licensing models.

Scalable pricing

Scalable pricing means a pricing scheme that provides the benefits of economies of scale. Below are pricing models commonly used for software products and how they fit in the new dynamically-scalable world.

  • Free - while this certainly sounds like the best option (and may very well be) the customer needs to be aware of the following:
- The free license of a software product typically does not include support: not an option for most mission critical applications.
- When you do pay extra for support, you will typically be charged just like any other run-time license on a per CPU basis.
- Make sure that the company behind the product has a sustainable business model, otherwise there is a good chance that it will either die when its funding dries up or change its license model to monetize its user base. That's fine, but all it means is that it's not really a free offering in the long run, and you don't know what the pricing model will be exactly.
- In terms of total cost of ownership (TCO), free products are not necessarily the cheapest option. TCO is dependent on many factors, for example, dependency on other products (and their license costs), the need for integration and maintenance, etc. See my post, Economies of non scale, for more on the topic.
  • Subscription model - With a subscription model you pay a fixed periodical fee, typically on an annual basis for infrastructure software, and on a monthly basis for SaaS. Subscription pricing is suitable for on-demand scalability as it provides the flexibility to grow or reduce cost based on the annual use of the product.
  • Pay per use - this model is even more flexible then subscription model as it gives you higher granularity. Pay per use is provides in various forms where the usage can be a measure of CPU utilization or bandwidth utilization. Amazon for example charge per machine utilization for its EC2 services and data-utilization for its data services.
  • Perpetual license - This model is used to buy licenses in advance and pay for support separately (normally 15-20% on top of the per CPU license). This is the most commonly used model with commercial software products, however, due to the large initial investment required by this model, it doesn't fit well with on-demand environment.
  • Enterprise unlimited license - This model enables you to pay premium price in advance (based on potential future usage) and gives you the freedom to use the software without any limit. This model fits to environment where you anticipate that over a fairly short period of time the usage of the product will become wide and therefore the pay-per use or any of the other models mentioned above will become more expensive.

Which model to choose?

Each of the models has pros and cons and therefore the answer depends on your situation. Also, over time, as the situation changes, you will probably realize you need a different license model, and so it becomes equally important that the product you choose will give you the freedom to move from one model to another in the future.

GigaSpaces scalable pricing

With GigaSpaces we continuously look into ways to make our software license cost fit the on-demand world. For example, we launched a free Start-Up program that provides a totally FREE version of GigaSpaces for startups (hundreds of start-ups have already signed up for this program since we launched it last year). We also provide a Pay-Per-Use model for those running on Amazon EC2.

We felt that even though this is a fairly flexible pricing, we could do better. As of our 6.6 release, we added the option to buy our software at a yearly subscription price, and we also launched a new package called XAP Standard Edition, which is sold at a very low price of $9,500k per package (not CPU) where the package includes two servers, 4 GigaSpaces nodes and up to 50 clients or remote servers.

These changes were designed to address the needs of developers looking to start running their applications at a relatively low scale, who need the full functionality of the product, but cannot afford the full XAP price. Another principle that we kept when we designed this package is that moving from Standard to Premium edition wouldn't require any change in your architecture or code - which means that you could always scale to the premium edition just by changing the license key.

Nati Shalom was part of the star-studded lineup of speakers that spoke at SYS-CON's Cloud Computing Expo. Between them, they covered every aspect of the hottest IT topic for years, with not just Amazon but also IBM, Microsoft, Google, Yahoo, Intel, HP and a host of others all offering, using or developing high-end computing services typically described as “cloud computing” - through which massively scalable IT-related capabilities are provided as a service using Internet technologies.

Forrester Research analyst James Staten calls cloud computing "classic disruptive innovation - where the mainstream dismisses the product and small companies have time to create a real differentiated value." But there are so many offerings just now that what infrastructure architects are looking for above all is a set of organizing principles they can use to guide them in choosing between them all.

With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
