The demand of cloud-based services has seen enormous growth over recent years. Infrastructure as a service (IaaS) and Platform as a service (PaaS) are two main types of cloud computing.
Infrastructure as a service (IaaS)
IaaS, or Infrastructure as a Service, works in a similar manner to traditional server hardware but operates in a virtual capacity. Instead of buying the physical hardware, We buy the infrastructure as a virtual service in a pay-as-you-go billing model through an IaaS provider. It gives you access to the resources like virtual machines and virtual storage and option to scale Infrastructure depending on processing and storage needs.
Larger companies may prefer IaaS because it gives them complete control over their apps, platforms, and infrastructure.
Platform as a service (PaaS)
Platform as a service provide a platform to customers for developing, running and managing the applications. It helps them to create custom applications without worrying about the servers and networking which is done by the third-party platform providers.
PaaS is best if you are looking for an easy, streamlined, and low-cost way to deploy specific use apps. You can develop and customize your application without worrying about the infrastructure or resources behind the platform
