Cloud computing is one of the most important technologies in modern software development. It allows businesses and developers to store data, run applications, and manage infrastructure over the internet instead of relying on physical servers.
In this guide by Mango Engineers, you will learn what cloud computing is, its service models (IaaS, PaaS, SaaS), real-world usage, and an introduction to AWS, Azure, and Google Cloud.
1. What is Cloud Computing?
Cloud computing is the delivery of computing services like servers, storage, databases, networking, and software over the internet (the cloud).
In Simple Terms:
Instead of buying and maintaining your own servers, you rent resources from cloud providers.
👉 Example:
When you upload photos to Google Drive or use online apps, you are using cloud computing.
2. Types of Cloud Services (IaaS, PaaS, SaaS)
1. IaaS (Infrastructure as a Service)
- Provides virtual servers and infrastructure
- You manage OS, applications, and data
👉 Example: Renting a virtual machine on AWS
2. PaaS (Platform as a Service)
- Provides platform to develop and deploy applications
- No need to manage infrastructure
👉 Example: Deploying apps without worrying about servers
3. SaaS (Software as a Service)
- Ready-to-use software over the internet
- No setup required
👉 Example: Gmail, Google Docs
3. Real-World Usage of Cloud Computing
Cloud computing is used everywhere:
- Streaming platforms (Netflix, YouTube)
- Social media apps (Instagram, WhatsApp)
- Online storage (Google Drive, Dropbox)
- E-commerce platforms (Amazon, Flipkart)
👉 Companies use cloud for scalability, security, and cost efficiency.
4. Introduction to AWS, Azure & Google Cloud
AWS (Amazon Web Services)
- Most popular cloud platform
- Offers services like EC2 (servers), S3 (storage)
- Widely used by startups and enterprises
Microsoft Azure
- Strong integration with Microsoft tools
- Popular in enterprise environments
Google Cloud Platform (GCP)
- Known for data and AI services
- Used for analytics and machine learning
5. Basics of AWS
AWS is the leading cloud platform and a great starting point for beginners.
Important AWS Services:
- EC2: Virtual servers
- S3: Storage service
- RDS: Database service
- Lambda: Serverless computing
What You Can Do with AWS:
- Host websites
- Deploy applications
- Store and manage data
👉 Learning AWS can open many career opportunities in cloud computing.
Why Cloud Computing is Important
- Reduces infrastructure cost
- Scales easily with demand
- High availability and reliability
- Essential skill for modern developers
