Infrastructure as a Service (IaaS) is a type of cloud computing service that provides virtualized computing resources over the internet. IaaS providers offer customers access to virtualized computing resources, such as virtual machines, storage, and networking, that can be used to run applications and store data. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

Platform as a Service (PaaS) is a type of cloud computing service that provides a platform for customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. PaaS providers offer customers a platform, including a development environment, runtime environment, and data storage, that can be used to build and deploy applications. Examples of PaaS providers include Heroku, AWS Elastic Beanstalk, and Google App Engine.

In summary, IaaS is lower level in the stack, it provides the infrastructure such as servers, storage, and networking, while PaaS is higher level in the stack, it provides a platform for customers to develop, run and manage their applications. Infrastructure as a Service

Infrastructure as a Service (IaaS) is a cloud computing model that enables businesses to rent virtualized computing resources, such as servers, storage, and networking, over the internet. With IaaS, companies can scale their IT infrastructure up or down as needed, without the high costs and complexity of building and maintaining their own physical infrastructure. IaaS providers, such as Amazon Web Services, Microsoft Azure and Google Cloud Platform, offer a variety of virtualized resources and services, including virtual machines, storage, and load balancing, that can be easily provisioned and managed through a web-based console or API. This allows businesses to focus on their core competencies and optimize their IT infrastructure for performance, cost, and scalability.
