Cloud computing is the delivery of computing services (such as storage, servers, databases, networking, software, and analytics) over the internet (“the cloud”) instead of relying on local computers or data centers.
Types of Cloud Computing
Cloud computing services can be categorized into three main types:
1️⃣ Infrastructure as a Service (IaaS)
- Provides virtual servers, storage, and networking.
- Users manage their operating systems and applications.
- Examples:
- 🟡 Amazon Web Services (AWS) EC2
- 🔵 Google Compute Engine (GCE)
- 🔷 Microsoft Azure Virtual Machines
2️⃣ Platform as a Service (PaaS)
- Provides a development platform, so developers don’t have to manage servers.
- Includes tools for coding, testing, and deploying applications.
- Examples:
- 🔥 Google App Engine
- ☁️ Heroku
- 🔵 Microsoft Azure App Services
3️⃣ Software as a Service (SaaS)
- Delivers software applications over the internet on a subscription basis.
- No need to install or maintain software locally.
- Examples:
- 📧 Google Workspace (Gmail, Drive, Docs)
- 📊 Microsoft Office 365
- 💼 Salesforce (CRM Software)
