Exam details
Amazon Web Services (AWS) is a comprehensive, secure, and scalable cloud computing platform provided by Amazon, offering over 200 fully featured services from data centers globally.
AWS provides benefits like agility, scalability, elasticity, global reach, pay-as-you-go pricing, security, and high reliability through its global infrastructure.
Cloud computing is the on-demand delivery of IT resources over the internet with pay-as-you-go pricing, instead of buying, owning, and maintaining physical data centers and servers.
The models are Infrastructure as a Service (IaaS) for virtualized computing resources, Platform as a Service (PaaS) for development platforms, and Software as a Service (SaaS) for ready-to-use software applications.
An AWS Region is a geographic area consisting of multiple isolated Availability Zones, each with independent power, cooling, and networking to enhance fault tolerance.
