Cloud Computing Deployment Models


Cloud model allows deploying a fully functional application on the cloud with all its components hosted on the cloud framework. Cloud applications can either be developed on the cloud platform itself or one can even migrate an existing application to cloud computing. Often, organizations migrate to the cloud for availing the benefits of cloud computing for their business processes.
Cloud applications can be built in two ways – using low-level infrastructural components or high-end services to stop wasting time, effort and energy on planning, managing, and scaling the technology infrastructure.


Hybrid deployment enables organizations to connect existing technology resources to cloud-based resources, efficiently. Hybrid deployment simplifies the process of connecting cloud and on-premise infrastructure for improved scalability and extending the capabilities of existing infrastructure. At the same time, hybrid deployment allows integration of cloud resources to internal systems.


On-premises model, also known as private cloud, can be implemented using virtualization or resource management tools. Though on-premises solutions are not as efficient as the cloud and doesn’t offer same cloud computing benefits, it is often used owing to its capability to offer dedicated resources. The deployment model is quite similar to legacy IT infrastructure but uses virtualization technologies and application management tools for improving resource utilization.

Cloud Computing Models

There are three main models for cloud computing. Each model represents a different part of the cloud computing stack.

Infrastructure as a Service

Infrastructure as a Service, also known as IaaS, consists of fundamental cloud and IT infrastructure offering IT solutions such as networking, hardware or virtual desktop computers and data storage capabilities. Infrastructure as a Service offers exemplary flexibility and deeper control over your IT resources and is quite similar to the existing IT infrastructure within an organization

Platform as a Service

Platform as a Service (PaaS) enables progressive organizations to focus on managing and deploying high-end applications without requiring managing hardware, OS and other IT infrastructure. PaaS brings unprecedented efficiencies to the operational processes as organization don’t have to deal with resource procurement, software maintenance, capacity planning, patching or any backend processes for running business applications.

Software as a Service

Software as a Service (SaaS) solutions offers an integrated and fully functional product or application, managed and operated by a service provider. Generally, SaaS solutions are end-user applications hosted on the cloud for remote access. SaaS is a highly scalable deployment model that eliminates the need for worrying about service maintenance and infrastructure management. Businesses only have to think of ways to use the particular product or software. A web-based SaaS application that doesn’t require server maintenance and OS compatibility is a great example of Software as a Service.
