Cloud computing is often described in three service models: IaaS, PaaS, and SaaS. Understanding the difference helps you choose the right approach for each workload. Here is a plain-language breakdown.
IaaS (Infrastructure as a Service)
IaaS provides the basic building blocks of computing, servers, storage, and networking, on demand. You manage the operating systems and applications, while the provider handles the physical infrastructure. Examples include AWS EC2 and Azure Virtual Machines. IaaS offers maximum control and flexibility.
PaaS (Platform as a Service)
PaaS adds a managed platform on top of infrastructure, including operating systems, databases, and development tools. Developers focus on building applications without managing the underlying servers. Examples include Azure App Service and Google App Engine. PaaS accelerates development.
SaaS (Software as a Service)
SaaS delivers complete, ready-to-use applications over the internet. You simply log in and use them, no installation or maintenance required. Examples include Microsoft 365 and Salesforce. SaaS offers the most convenience.
How to Choose
Use IaaS when you need control, PaaS when you want to build apps faster, and SaaS when you want ready-made software. Most businesses use a mix. Rapid Scale IT helps you choose and manage the right blend for your needs.
