![]() In this report we look at all three categories in detail however a very simplified way of differentiating these flavors of Cloud Computing is as follows The diagram below depicts the Cloud Computing stack – it shows three distinct categories within Cloud Computing: Software as a Service, Platform as a Service and Infrastructure as a Service. ![]() This is especially true since in recent years there has been a move by traditional software vendors to market solutions as “Cloud Computing” which are generally accepted to not fall within the definition of true Cloud Computing, a practice known as “cloud-washing.” More than a semantic argument around categorization, we believe that in order to maximize the benefits that Cloud Computing brings, a solution needs to demonstrate these particular characteristics. Billing is metered and delivered as a utility service Capability can scale to cope with demand peaks Resources are pooled across multiple customers Ability to access the service via standard platforms (desktop, laptop, mobile etc) The ability for an end user to sign up and receive services without the long delays that have characterized traditional IT NIST also offers up several characteristics that it sees as essential for a service to be considered “Cloud”. What this means in plain terms is the ability for end users to utilize parts of bulk resources and that these resources can be acquired quickly and easily. The NIST definition runs to several hundred words but essentially says that Ĭloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. The generally accepted definition of Cloud Computing comes from the National Institute of Standards and Technology (NIST). We will also provide some guidance on situations where particular flavors of Cloud Computing are not the best option for an organization.Ĭloud Computing is often described as a stack, as a response to the broad range of services built on top of one another under the moniker “Cloud”. In this report we will explain the different types of Cloud Computing services commonly referred to as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) and give some examples and case studies to illustrate how they all work. Since the Cloud is a broad collection of services, organizations can choose where, when, and how they use Cloud Computing. In order to truly understand how the Cloud can be of value to an organization, it is first important to understand what the Cloud really is and its different components. Cloud Computing is a broad term that describes a broad range of services.Īs with other significant developments in technology, many vendors have seized the term “Cloud” and are using it for products that sit outside of the common definition.
