Service Model of Cloud Computing (Iaas, Saas, Paas)
- 2. About Service Models in Cloud Computing Service models of cloud computing refer to the different levels of services provided over the cloud, offering varying degrees of control and management. The three main models are: IaaS (Infrastructure as a Service): Provides virtualized infrastructure like storage and networking. 1. PaaS (Platform as a Service): Offers a platform for developers to build and deploy applications without managing infrastructure. 2. SaaS (Software as a Service): Delivers fully managed software applications over the internet, accessible through a web browser. 3.
- 3. Paas(Platform as a service) Platform as a Service (PaaS) is a cloud computing service model that provides a platform allowing customers to develop, run, and manage applications without dealing with the complexities of managing underlying infrastructure, such as servers, storage, or networking. PaaS provides a ready-to-use environment that includes software development tools, operating systems, databases, and application frameworks.
- 4. IaaS(Infrastructure as a Service) Infrastructure as a Service (IaaS) is a cloud computing service model that provides virtualized computing resources over the internet. IaaS offers the fundamental building blocks for cloud IT, including virtual machines, storage, networking, and computing power, without the need for businesses to invest in and maintain physical hardware. Users can rent these resources on a pay-as-you-go basis, allowing for flexibility and scalability.
- 5. SaaS(Software as a service) Software as a Service (SaaS): SaaS is the most user- friendly service model, where applications are hosted and managed by third-party providers and are accessible over the internet. With SaaS, users don't need to install or maintain any software, as everything is accessed via a web browser. Examples of SaaS include Google Workspace (formerly G Suite), Microsoft 365, and Salesforce. SaaS offerings can scale to accommodate more users or increased demand, with minimal effort from the user’s side. SaaS applications are typically accessed through a web browser, making them platform- independent and easy to use from any device with an internet connection. Web Browser Scalability
