Why Cloud? ☁️
In today's digital world, businesses need scalable, flexible, and cost-effective solutions to manage their IT infrastructure. This is where cloud computing comes in! Instead of maintaining physical servers, companies can leverage cloud platforms like AWS (Amazon Web Services) to store, process, and manage data efficiently.
What is Cloud Computing?
Benefits of Cloud Computing 🚀
✅ Cost-Effective – Pay only for what you use.
✅ Scalability – Easily scale up or down as needed.
✅ Flexibility – Access from anywhere in the world.
✅ Security – Advanced security measures to protect data.
✅ Disaster Recovery– Automatic backups and failover mechanisms.

On-Premise🏢 vs. Cloud ☁️
| Feature | On-Premise 🏢 | Cloud ☁️ |
| Upfront Cost | High (Hardware & Maintenance) | Low (Pay-as-you-go) |
| Scalability | Limited | High |
| Security | Fully Controlled | Managed by Provider |
| Maintenance | IT Team Required | Managed by Cloud Provider |
| Accessibility | Limited to Network | Accessible Globally |
🔹 With cloud computing, businesses can focus on innovation rather than infrastructure maintenance!
Types of Cloud Deployment Models 🌎
Public Cloud ☁️ – Shared resources hosted by a cloud provider (e.g., AWS, Azure, Google Cloud).
Private Cloud 🏠 – Dedicated cloud environment for a single organization.
Hybrid Cloud 🔄 – Combination of both public and private cloud, offering flexibility and security.
Cloud Service Models 🏗️
AWS provides three major cloud service models:
1️⃣ Infrastructure as a Service (IaaS) 🏗️ – Provides virtual servers, storage, and networking (e.g., AWS EC2, S3).
2️⃣ Platform as a Service (PaaS) 🔧 – Provides development platforms and tools (e.g., AWS Elastic Beanstalk, Lambda).
3️⃣ Software as a Service (SaaS) 📦 – Ready-to-use applications over the internet (e.g., Gmail, Dropbox, Salesforce).
🔹 Analogy: Think of IaaS as renting an empty apartment, PaaS as a furnished one, and SaaS as staying in a hotel room! 🏨
What is AWS EC2? 🖥️
Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It allows businesses to run virtual machines (instances) on AWS infrastructure without needing to invest in physical hardware.
Why Use EC2? 🤔
✅ Scalability – Quickly scale up or down based on demand.
✅ Cost-Effective – Pay only for the compute resources you use.
✅ Flexibility – Choose different instance types based on workload.
✅ Security – AWS provides built-in security and compliance features.
✅ Integration – Seamlessly connects with other AWS services.
EC2 Instance Types & Pricing 💰
AWS EC2 offers various instance types to suit different workloads:
🔹 General Purpose (e.g., t3, m5) – Balanced performance, suitable for web servers and small databases.
🔹 Compute Optimized (e.g., c5, c6g) – High-performance processors for compute-heavy applications.
🔹 Memory Optimized (e.g., r5, x1e) – Ideal for in-memory databases and big data analytics.
🔹 Storage Optimized (e.g., i3, d2) – Designed for applications requiring high disk throughput.
🔹 GPU Instances (e.g., p3, g5) – Best for AI/ML workloads and graphics-intensive applications.
Pricing 📊
AWS EC2 pricing depends on factors such as instance type, region, and usage model:
✅ On-Demand – Pay for compute capacity per hour or second, with no upfront commitment.
✅ Reserved Instances – Save up to 75% by committing for 1 or 3 years.
✅ Spot Instances – Get unused EC2 capacity at up to 90% discount but with potential interruptions.
✅ Savings Plans – Flexible pricing model that provides discounts for consistent usage.
Steps to Install Linux on EC2:
Launch an EC2 Instance – Navigate to EC2 and click Launch Instance.
Choose a Linux AMI (Amazon Machine Image) – Select a Linux distribution like:
Amazon Linux 2 (Optimized for AWS)
Ubuntu (Popular for general use)
Red Hat Enterprise Linux (RHEL) (Enterprise-ready)
Select an Instance Type – Choose a size based on your needs (e.g., t2.micro for free tier users).
Configure Security Group – Allow SSH access by opening port 22. (Here I am allowing HTTP & HTTPS as I will be needing it further)
Download Key Pair – Click on create new Key pair. This will be used to securely connect to the instance.
Launch –
🎉 Congratulations! You now have a running EC2 instance. 🚀
Connect – Once launched, connect via SSH or any other method you wish to:
Start Using Linux! 🎉
bashCopyEditssh -i your-key.pem ec2-user@your-instance-ip
Conclusion 🎯
AWS Cloud is a game-changer, offering cost savings, scalability, and flexibility. Whether you're a developer, business owner, or cloud enthusiast, understanding AWS can open new opportunities in the tech world.
