During the first week of the AWS re/Start it was all about Cloud Computing 101
What exactly is Cloud Computing ?
Cloud Computing in layman's terms is essentially using someone else's computer—but in a highly structured, scalable, and secure way. Instead of running applications or storing data on your personal computer or a local server, you rent computing power, storage, and services from a cloud provider like AWS, Microsoft Azure, or Google Cloud.
So in short Cloud computing is the delivery of computing services—such as servers, storage, databases, networking, software, and analytics—over the internet
Key Characteristics
1️⃣ On-Demand Self-Service – Users can provision resources as needed.
2️⃣ Broad Network Access – Services are accessible over the internet.
3️⃣ Resource Pooling – Computing resources are shared across multiple users.
4️⃣ Scalability & Elasticity – Scale resources up or down based on demand.
5️⃣ Pay-as-You-Go Pricing – Only pay for what you use, reducing upfront costs.
Types of Cloud Computing Services
IaaS (Infrastructure as a Service): Provides virtual machines, storage, and networks (e.g., AWS EC2, Google Compute Engine).
PaaS (Platform as a Service): Offers a managed environment for application development (e.g., AWS Elastic Beanstalk, Google App Engine).
SaaS (Software as a Service): Delivers fully functional applications over the internet (e.g., Gmail, Dropbox, Microsoft 365).
Cloud Deployment Models
Public Cloud – Services are offered over the internet by providers like AWS, Azure, and Google Cloud.
Private Cloud – Cloud resources are used exclusively by one organization.
Hybrid Cloud – A mix of public and private cloud solutions.
Multi-Cloud – Using multiple cloud providers for flexibility and reliability.
** Benefits of Cloud Computing**
✅ Cost Efficiency – Reduces capital expenses on hardware.
✅ Flexibility – Access from anywhere, anytime.
✅ Security – Built-in encryption, compliance, and access controls.
✅ Disaster Recovery – Data backups and failover mechanisms.
✅ Innovation – Enables rapid development and testing of new technologies
