Cloud

3. Virtual Services
● Like Gmail is an email service (Built on Dockers on cloud)
● Whatsapp is a chat service
● Dropbox is a storage service (Built on AWS!)
● Websites are content as Service

4. Type - IT / Software Services
● NO physical access!
● Behind the scenes there are physical servers but not for end-users to see or
know about

5. Available via Internet
● Like majority of the applications
● Can be accessed via Private Network (VPN, Direct Connect)
● Both customers and consumers

6. Environment - Virtual
● Virtual Machines
● Containers / Dockers

7. Use via Website, CLI, SDK, IaC
● https://console.aws.amazon.com/
● Command Line Interface (CLI) / Terminal / Dos / Powershell
● Software Development Kit (SDK)
● Infrastructure as Code (IaC).

8. Other aspects
● Helps to develop applications
● Physically in Regions
● Utility Pricing
● Scalable, Agile, Reliable, etc

9. What is Cloud
● Somebody’s else computer
● Accessible via Internet
● Everything is virtual
● The computer is HUGE
● There are 3 models of Cloud Computing (IaaS, PaaS, SaaS)

11. Requirement / Benefits
