Types of Cloud Computing Explained
What is Cloud Computing? You hear about “Cloud Computing” all of the time and you probably wonder what is the difference between cloud computing, the Internet, local storage and hosted solution. In simplest terms, cloud computing means storing and accessing your data and programs over the Internet instead of your hard drive. The main advantages of cloud computing, compared to local computing, are: scalability, reliability, usability and cost effectiveness.
• Public • Private • Hybrid • Community Cloud Cloud computing can be described in 2 ways: Cloud location Cloud service • IaaS (Infrastructure as a Service) • PaaS (Platform as a Service) • SaaS (Software as a Service) • xaaS (storage, database, information etc)
Cloud Location Public Cloud When we talk about public cloud, we mean that the whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. The location remains, thus, separate from the customer and he has no physical control over the infrastructure. As public clouds use shared resources, they do excel mostly in performance and scalability but are also most vulnerable to various attacks.
Cloud Location Private Cloud Private cloud means using a cloud infrastructure (network) solely by one customer/organization. It is not shared with others, yet it is remotely located. If the cloud is externally hosted. The companies have an option of choosing an on-premise private cloud as well, which is more expensive, but they do have a physical control over the infrastructure. The security and control level is highest while using a private network. Yet, the cost reduction can be minimal, if the company needs to invest in an on- premise cloud infrastructure.
Cloud Location Hybrid Cloud Hybrid cloud means using both private and public clouds, depending on their purpose, cost & security optimization and accessibility by end-users.
For example, public cloud can be used to interact with customers, while keeping their data secured through a private cloud. Private vs Public Cloud (Image Source: TalkCloudComputing)
Cloud Location Community Cloud Community Cloud implies an infrastructure that is shared between organizations, usually with the shared data and data management concerns. For example, a community cloud can belong to a government of a single country. Community clouds can be located both on and off the premises.
Cloud Service The most popular services of the cloud are that of either infrastructure, platform, software, or storage. IaaS (Infrastructure-as-a-Service) As explained before, the most common cloud service is that one offering data storage disks and virtual servers, i.e. infrastructure. Examples of Infrastructure-as-a-Service (IaaS) companies are Amazon, Rackspace, ca technologies etc.
Cloud Service PaaS (Platform-as-a-Service) If the cloud offers a development platform, and this includes operating system, programming language execution environment, database, and web server, the model is known as Platform-as-a-Service (PaaS), examples of which are Google App Engine, Microsoft Azure, Salesforce. Operating system can be frequently upgraded and developed with PaaS, services can be obtained from diverse sources, and programming can be worked in teams (geographically distributed)
Cloud Service SaaS (Software-as-a-Service) Software-as-a-Service (SaaS), finally, means that users can access various software applications on a pay-per-use basis. As opposed to buying licensed programs, often very expensive. Examples of such services include widely used Gmail, or Google Docs.

Cloud Service The longer list of cloud services would include: • Storage as a service (STaaS) • Security as a service (SECaaS) • Data as a service (DaaS) • Test environment as a service (TEaaS) • Desktop as a Service (DaaS) • Api as a Service (APIaaS)
What Can You Do? Once you have understood the types of cloud computing, based on location and services, the most important step is to choose the right type of cloud and service, for a specific task with your clients. Visit www.globaldots.com for further info.
