Study Notes
Cloud Computing Importance
- Cloud computing is essential for current enterprises due to its unique features, such as on-demand self-services, high adaptability, and flexibility of leveraging technology-based solutions without hosting servers.
- These advantages are achieved through various cloud services, which have distinct benefits and drawbacks depending on the service model and deployment.
Basic Cloud Computing Service Models
- Cloud computing service models are categorized into three layers: Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS).
- These models are differentiated based on the services offered by cloud providers and the objects that provide services for customers.
Platform-as-a-Service (PaaS)
- PaaS allows web developers to utilize a complete virtualized platform for application or platform development.
- It consists of multiple subsystems and interfaces, involving product development procedures, interface development, database development, data storage, system testing, and other processes related to application development.
- Subscribers can build enterprise-level applications in a customized manner, following the enterprises' strategies and policies.
- PaaS provides an open Web-based development platform, enabling small or medium-size enterprises to explore their markets by leveraging advanced computing techniques.
Infrastructure-as-a-Service (IaaS)
- IaaS allows enterprises to access costly computing resources within a required scope, such as database, data storage, processors, memories, routers, and networks.
- Cloud service providers can supply same-level services to multiple clients simultaneously, maximizing the capability of the infrastructure.
- Clients can purchase services from diverse cloud service providers to meet their business requirements.
- IaaS is an Internet Protocol (IP)-based model that delivers services regardless of the geographic location of the infrastructure.
- Customers can focus on business process improvement and strategy-making, without worrying about technical complexity and geographic restrictions.
