Study Notes
Public Cloud: Understanding the Service Models
Public cloud is a model of cloud computing that provides services over the internet. It allows users to access computing resources, such as servers, storage, applications, and services, without the need to maintain their own physical infrastructure. In this model, cloud service providers offer a range of services to customers, which can be classified into three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These service models offer different levels of abstraction and control to users.
Infrastructure as a Service (IaaS)
IaaS is the most basic service model in public cloud. It provides users with virtualized computing resources, such as servers, storage, and networking, which are delivered over the internet. IaaS allows users to migrate their workloads to a virtual machine (VM) and configure the VM and storage as needed. IaaS providers offer various instance sizes and types, which can be customized to meet different workload requirements. This model is suitable for companies that want full control over their applications and need to manage their own software and operating systems.
Platform as a Service (PaaS)
PaaS is a service model that offers a platform for users to run and develop their applications. It provides a complete development and deployment environment, including tools, libraries, and frameworks, over the internet. PaaS allows users to focus on their application development without worrying about the underlying infrastructure. Examples of PaaS products include Salesforce Lightning, AWS Elastic Beanstalk, and Google App Engine.
Software as a Service (SaaS)
SaaS is a service model that delivers software applications over the internet. It offers users access to software applications and databases from any location with an internet connection. SaaS applications include productivity tools, email services, and other business applications. In the SaaS model, users gain access to software without the need to install or manage it on their own infrastructure.
Function as a Service (FaaS)
FaaS, also known as serverless computing, is a newer service model that lets users run code in the cloud without worrying about the underlying infrastructure. FaaS allows developers to create and deploy functions that respond to events or triggers, abstracting server and infrastructure management. This model is particularly useful for building and deploying event-driven applications and microservices.
Public cloud providers offer these service models to cater to different needs and requirements of businesses, allowing them to choose the most suitable model for their specific use cases.
