What is Cloud Computing?
Cloud computing refers to the delivery of IT resources such as storage, computing power, and applications over the internet. It reduces the need for local infrastructure and increases flexibility.
How does Cloud Computing work?
Service models include:
- IaaS (Infrastructure as a Service): e.g., AWS, Microsoft Azure
- PaaS (Platform as a Service): Development platforms for building applications
- SaaS (Software as a Service): Ready-to-use software delivered online, e.g., Microsoft 365
Benefits of Cloud Computing:
- Scalability
- Reduced IT costs
- Access from any device with internet
- Automatic updates and security patches
Challenges of Cloud Computing:
- External data storage can create security risks
- Requires stable internet connectivity
- Potential vendor lock-in makes it hard to switch providers
Use Cases:
- Data processing and AI applications
- Backup and disaster recovery
- Communication and collaboration tools
- Hybrid cloud solutions
