Intro in AWS
? Introduction to AWS
? What is AWS?
Amazon Web Services (AWS) is a cloud computing platform provided by Amazon. It allows businesses, developers, and individuals to access computing resources over the internet instead of owning and maintaining physical servers and data centers.
Think of it like renting computing power, storage, databases, and more — only when you need it.
? Why Was AWS Created?
Before AWS, companies had to:
Buy expensive servers and infrastructure upfront.
Predict future demand (which often led to waste).
Manage hardware, networking, security, etc.
AWS solved this by offering on-demand access to IT resources, billed only for what you use, and scalable with just a few clicks.
? Key Features of AWS
Scalability: Instantly increase or decrease resources as needed.
Flexibility: Supports multiple programming models, platforms, and operating systems.
Cost-Effective: Pay only for what you use (no long-term contracts).
Global Infrastructure: Data centers in multiple regions worldwide.
Security: Strong built-in security and compliance controls.
