Part -2 OnPrem (On-Premises) Example : A company uses its own data center to host its servers, databases, and applications. Use Case : A financial institution that requires high security and control over its data and infrastructure. Advantages : Full control over hardware, security, and compliance. Disadvantages : High upfront costs, maintenance overhead, and limited scalability. IaaS (Infrastructure as a Service) Example : Amazon Web Services (AWS) EC2 instances. Use Case : A startup needs scalable computing resources without the need to manage physical hardware. Advantages : Scalability, flexibility, and reduced upfront costs. Disadvantages : Requires management of OS, middleware, runtime, data, and applications. PaaS (Platform as a Service) Example : Google App Engine. Use Case : A software development team needs a platform to deploy and manage applications without worrying about the underlying infrastructure. Advantages : Simplified application deployment, automatic scaling, and reduced management overhead. Disadvantages : Limited control over the underlying infrastructure and potential vendor lock-in.
