Cloud is the future of computing. It is about outsourcing of IT services and infrastructure to make them accessible remotely via the Internet. Utilizing cloud-computing models boosts not only productivity but also provide a competitive edge to organizations. The growing popularity of cloud computing has given rise to different types of cloud service deployment models and strategies. Therefore, today there exists a variety of enterprise cloud solutions depending on the degree of desired outsourcing needs.

Different Types Of Cloud Computing Deployment Models

 

Most cloud hubs have tens of thousands of servers and storage devices to enable fast loading. It is often possible to choose a geographic area to put the data “closer” to users. Thus, deployment models of cloud computing are categorized based on their location. To know which deployment model would best fit the requirements of your organization, let us first learn about the types of cloud deployment models.

 

Cloud computing deployment models are based on location. In order to know which deployment model would best suit your organization requirements, it is necessary to know the four deployment types.

Public Cloud is a type of hosting in which cloud services are delivered over a network for public use.

  • Customers do not have any control over the location of the infrastructure.

  • The cost is shared by all users, and are either free or in the form of a license policy like pay per user.

  • Public clouds are great for organizations that require managing the host application and the various applications users use.

Private Cloud is a cloud infrastructure that is solely used by one organization.

  • It gives organizations greater control over security and data which is safeguarded by a firewall and managed internally.

  • It can be hosted internally or externally.

  • Private clouds are great for organizations that have high-security demands, high management demands and uptime requirements.

Hybrid Cloud uses both private and public clouds but can remain separate entities.

  • Resources are managed and can be provided either internally or by external providers.

  • A hybrid cloud is great for scalability, flexibility and security.

  • An example of this is an organization can use public cloud to interact with customers, while keeping their data secured through a private cloud.

Community Cloud is an infrastructure that is mutually shared between organizations that belong to a particular community.

  • The community members generally share similar privacy, performance and security concerns.

  • An example of this is a community cloud at banks, government in a country, or trading firms.

  • A community cloud can be managed and hosted internally or by a third party provider.

  • A community cloud is good for organizations that work on joint ventures that need centralized cloud computing ability for managing, building and executing their projects.

Cloud Service Models focus on providing some type of offering to their clients.

  • Software as a Service is a type of cloud that offers an application to customers or organizations through a web browser. The data for the app runs on a server on the network, not through an app on the user’s computer. Software is usually sold via subscription

    • Examples of SaaS are Salesforce, Google Docs, Office 365, Basecamp etc.

  • Infrastructure as a Service provides the hardware and usually virtualized OS to its customers. Software is charged only for the computing power that is utilized, usually CPU hours used a month.

    • Examples of IaaS are Amazon EC2, Rackspace, Google Compute Engine etc.

  • Platform as a Service provides networked computers running in a hosted environment, and also adds support for the development environment. PaaS offerings generally support a specific program language or development environment. Deploying your app in this environment, you can take advantage of dynamic scalability, automated database backups without need to specifically code for it. PaaS is billed as an additional cost on top of the IaaS charges.

    • Examples of PaaS are Google App Engine, Cloud Foundry, Engine Yard Etc.
