Cloud Service Models Explained
When exploring cloud computing, it’s essential to understand the different service models available. These models define what type of resources are provided and how much control you have over the infrastructure. The primary cloud service models are Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), Infrastructure-as-a-Service (IaaS), and Function-as-a-Service (FaaS). Let’s explore each of these in detail:
1. Software-as-a-Service (SaaS)
- SaaS is a model where software is accessed on-demand, typically through a web browser.
- With SaaS, you don’t need to install anything on your local device. The software is hosted on cloud servers and is accessible over the internet.
- The vendor manages all aspects of the software, including maintenance, updates, and backups.
- Examples of SaaS include Microsoft Office 365 and Google Mail. You simply open the application through your web browser.
