Cloud Pricing Models

An analysis of existing pricing models and why there's so much diversity

The current pricing of Cloud services offers a wide range of configuration, choices and price points for the users. This in turn creates a lot of confusion for the buyer as it's difficult to measure the value at a specific price point. The objective of this article is to analyze the existing pricing models and reasons behind why there is so much diversity. In the following four sections, this article attempts to:

  1. Compare approx. 27 models of pricing derived from the scholarly articles
  2. Recommend a derived pricing model relevant to the cloud services.
  3. Validate the model by mapping it to the pricing of services by few key vendors.
  4. Analyze reasons behind the pricing in use by various vendors and future trends.

1. Generic Pricing Models

  • Osterwalder (2004) classified the pricing models around fixed, differential and market based pricing. He suggested that the fixed and differential pricing mechanisms produce prices that depend on customer/ product / Service characteristics, volume, but are not based on real-time market conditions. Market based pricing stands for pricing mechanisms that produce prices based on real-time market conditions.
  • Harmon et al. (2009) suggested a factor based pricing mechanism (cost + value).
  • Denne (2007) discussed various advanced ways to implement pay per use pricing mechanism.
  • Paleologo (2004) suggested that traditional pricing mechanisms such as cost-plus pricing may be inadequate in on-demand services environment due to dynamic factors in cloud computing as shorter contracts, reduced switching costs, customer lock-in, uncertain demand, and shorter life cycles etc.
  • Some authors have also suggested other ways of classification such as resource based Vs. Feature based or Operational (Pay per Use) Vs. Availability (subscription).
  • The table below provides a summary of all pricing models which I believe covers almost all possible ways of pricing and there is a fair bit of overlap in all the studies.

2. A Derived Pricing Model for Cloud Computing
From this article's perspective, we classify the pricing models which are more of less a combination of the discussed pricing mechanisms.

3. Usage Based Pricing (Pay per use) with factor based variations.

4.  Subscription Pricing (Commitment / Reserve / Availability Pricing) with factor based variations.

5.       Market Based Pricing

6.       Pricing Strategy (More relevant from a marketing perspective)

The 17th International Cloud Expo has announced that its Call for Papers is open. 17th International Cloud Expo, to be held November 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA, brings together Cloud Computing, APM, APIs, Microservices, Security, Big Data, Internet of Things, DevOps and WebRTC to one location. With cloud computing driving a higher percentage of enterprise IT budgets every year, it becomes increasingly important to plant your flag in this fast-expanding bu...
Over the years, a variety of methodologies have emerged in order to overcome the challenges related to project constraints. The successful use of each methodology seems highly context-dependent. However, communication seems to be the common denominator of the many challenges that project management methodologies intend to resolve. In this respect, Information and Communication Technologies (ICTs) can be viewed as powerful tools for managing projects. Few research papers have focused on the way...
As the world moves from DevOps to NoOps, application deployment to the cloud ought to become a lot simpler. However, applications have been architected with a much tighter coupling than it needs to be which makes deployment in different environments and migration between them harder. The microservices architecture, which is the basis of many new age distributed systems such as OpenStack, Netflix and so on is at the heart of CloudFoundry – a complete developer-oriented Platform as a Service (PaaS...

There is no question that the cloud is where businesses want to host data. Until recently hypervisor virtualization was the most widely used method in cloud computing. Recently virtual containers have been gaining in popularity, and for good reason. In the debate between virtual machines and containers, the latter have been seen as the new kid on the block – and like other emerging technology have had some initial shortcomings. However, the container space has evolved drastically since coming on...

Software is eating the world. Companies that were not previously in the technology space now find themselves competing with Google and Amazon on speed of innovation. As the innovation cycle accelerates, companies must embrace rapid and constant change to both applications and their infrastructure, and find a way to deliver speed and agility of development without sacrificing reliability or efficiency of operations. In her Day 2 Keynote DevOps Summit, Victoria Livschitz, CEO of Qubell, discussed...
How can you compare one technology or tool to its competitors? Usually, there is no objective comparison available. So how do you know which is better? Eclipse or IntelliJ IDEA? Java EE or Spring? C# or Java? All you can usually find is a holy war and biased comparisons on vendor sites. But luckily, sometimes, you can find a fair comparison. How does this come to be? By having it co-authored by the stakeholders. The binary repository comparison matrix is one of those rare resources. It is edite...
There’s a lot of discussion around managing outages in production via the likes of DevOps principles and the corresponding software development lifecycles that does enable higher quality output from development, however, one cannot lay all blame for “bugs” and failures at the feet of those responsible for coding and development. As developers incorporate features and benefits of these paradigm shift, there is a learning curve and a point of not-knowing-what-is-not-known. Sometimes, the only way ...
Working with Big Data is challenging, especially when decision makers depend on market insights and intelligence from your data but don't have quick access to it or find it unusable. In their session at 6th Big Data Expo, Ian Khan, Global Strategic Positioning & Brand Manager at Solgenia; Zel Bianco, President, CEO and Co-Founder of Interactive Edge of Solgenia; and Ermanno Bonifazi, CEO & Founder at Solgenia, discussed how a revolutionary cloud-based BI along with mobile analytics is already c...
Hardware will never be more valuable than on the day it hits your loading dock. Each day new servers are not deployed to production the business is losing money. While Moore's Law is typically cited to explain the exponential density growth of chips, a critical consequence of this is rapid depreciation of servers. The hardware for clustered systems (e.g., Hadoop, OpenStack) tends to be significant capital expenses. In his session at Big Data Expo, Mason Katz, CTO and co-founder of StackIQ, disc...
Container frameworks, such as Docker, provide a variety of benefits, including density of deployment across infrastructure, convenience for application developers to push updates with low operational hand-holding, and a fairly well-defined deployment workflow that can be orchestrated. Container frameworks also enable a DevOps approach to application development by cleanly separating concerns between operations and development teams. But running multi-container, multi-server apps with containers ...
There is no doubt that Big Data is here and getting bigger every day. Building a Big Data infrastructure today is no easy task. There are an enormous number of choices for database engines and technologies. To make things even more challenging, requirements are getting more sophisticated, and the standard paradigm of supporting historical analytics queries is often just one facet of what is needed. As Big Data growth continues, organizations are demanding real-time access to data, allowing immed...
