Study Notes
- This section introduces the Cloud and Cloud Computing
- It aims to provide context for understanding the cloud's usefulness and functionality
How Websites Work
- A web browser (client) accesses a server to view a website
- This involves a network connection between the client and server
- The client uses the network to route data packets to the server
- The server replies, enabling the client to view the website
- Clients and servers use IP addresses to locate each other, similar to sending letters via postal mail
Server Components
- CPU: Performs computations and calculations
- RAM (Memory): Provides fast storage and retrieval of information
- CPU and RAM together act like a "brain," handling computation and memory
- Storage: Long-term data storage for files and databases
- Database: Structured data storage for easy searching and querying
- Networking components: Routers, switches, and DNS servers
IT Terminology
- Network: A collection of interconnected cables, routers, and servers
- Router: Forwards data packets between computers across networks, directing packets on the internet
- Switch: Directs packets to the correct client within a local network
Traditional IT
- Traditionally, websites and companies started with servers in homes or garages
- As a website grows, more servers are added, eventually requiring a dedicated data center
- Data centers house servers and allow for scaling by adding more servers
Problems with Traditional IT
- Rent, power, cooling, and maintenance costs for data centers
- Time-consuming process to add or replace servers
- Limited scaling ability
- Requirement for a 24/7 team to monitor infrastructure
- Risk of disasters like earthquakes, power shutdowns, or fires
The Cloud as a Solution
- The cloud offers a way to externalize IT infrastructure
- It helps alleviate the problems associated with traditional IT setups
