Cloud computing is a form of computing that relies on sharing computer resources instead of having local servers or personal devices to handle applications. Examples of cloud computing include: • Software-as-a-Service (SaaS): This involves the delivery of software over the internet from a third party provider.
• Platform-as-a-Service (PaaS): This provides access to an entire platform, including operating system, database, and scripting language. • Infrastructure-as-a-Service (IaaS): This offers users access to virtualized hardware such as storage and networking services. All these examples illustrate how cloud computing enables businesses to reduce costs by outsourcing their IT infrastructure needs without sacrificing reliability or performance.
What are the 4 Types of Cloud Computing?
Cloud computing can be broadly categorized into 4 types: * Infrastructure as a Service (IaaS): This is the most basic level of cloud computing. It allows users to access virtualized computing resources such as servers, storage and networking over the internet.
* Platform as a Service (PaaS): PaaS provides users with a platform, tools and services needed to build applications on top of a cloud infrastructure. It helps developers focus less on managing underlying infrastructure and more on developing their applications quickly. * Software as a Service (SaaS): SaaS is one of the most popular models for delivering software over the internet.
Applications are hosted by service providers in their own data centers and accessed by users through browsers or mobile apps from anywhere at any time. * Function as a Service (FaaS): FaaS is an event-driven compute model which lets developers create serverless functions that can be triggered when certain events occur or when specific conditions are met without worrying about setting up or maintaining underlying infrastructure components like servers and networks.
