Cloud computing allows organizations to access computing resources over the internet on an as-needed basis. It provides cost savings over owning physical infrastructure by using a pay-as-you-go model. A wide variety of organizations use cloud computing for applications like data backup, email, and customer-facing web applications. The main types of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), which provide different levels of control over IT resources. Cloud computing allows MSMEs flexibility and cost savings while helping them adapt to Industry 4.0 through increased data accessibility, customization, and collaboration across teams.
