Introduction to AWS: A Beginner’s Guide to Cloud Computing

What is Cloud Computing?

Cloud computing is the delivery of computing services—such as servers, storage, databases, networking, software, and analytics—over the internet ("the cloud"). Instead of owning and maintaining physical data centers, businesses can access technology services on-demand from cloud providers, paying only for what they use.

Cloud computing offers:

• Scalability – Easily scale resources up or down based on demand.

• Cost Efficiency – Pay-as-you-go pricing eliminates large upfront investments.

• Flexibility – Access services from anywhere with an internet connection.

• Reliability – Cloud providers offer high availability and disaster recovery.

Public Cloud vs. Private Cloud

Public Cloud

• Owned and operated by third-party providers (e.g., AWS, Azure, Google Cloud).

• Resources are shared among multiple customers.

• Highly scalable and cost-effective.

• No maintenance required from the user.

Private Cloud

• Dedicated infrastructure for a single organization.

• More control over security and compliance.

• Higher cost due to exclusive hardware.

• Requires in-house IT management.

Hybrid Cloud combines both, allowing businesses to keep sensitive data on-premises while leveraging the public cloud for scalability.

Why is Public Cloud So Popular?

1. Cost Savings – No need for expensive hardware; pay only for what you use.

2. Global Reach – Deploy applications worldwide in minutes.

3. Automatic Updates – Cloud providers handle security patches and upgrades.

4. Disaster Recovery – Built-in backup and redundancy.

5. Innovation Speed – Quickly test and deploy new technologies like AI and IoT.
