Why Use AWS?

The point: Companies move to AWS because it is cheaper, faster, and more flexible than running their own data centres. Understanding the benefits explains why the cloud took over.

The main benefits

• Pay-as-you-go — no big upfront cost; pay only for what you use, by the hour or second
• Scalability — handle a traffic spike by adding servers in minutes, then scale back down
• Speed — launch a server in seconds instead of buying hardware for weeks
• Global reach — deploy close to your users anywhere in the world
• Reliability & security — AWS runs hardened data centres most companies could never build themselves

CapEx vs OpEx

Traditional IT is a big capital expense (buy servers, hope you guessed the size right). The cloud turns that into a flexible operating expense — you scale spending with actual usage, up or down.

💡 Takeaway: the cloud removes the guesswork and upfront cost of owning infrastructure, which is why startups and giants alike rely on it.
