The document discusses cloud computing as a model for efficient resource access and emphasizes the importance of virtualization, which allows multiple operating systems to run concurrently. It outlines the pros and cons of virtualization and introduces containers as a lightweight alternative, highlighting their benefits and drawbacks. Additionally, it provides information on the Go programming language and its significance in cloud computing, particularly with Docker and Kubernetes.

2. Cloud Computing

3. "Cloud Computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of
configurable computing resources (e.g., networks, servers,
storage, applications, and services) that can be rapidly
provisioned and released with minimal management effort or
service provider interaction."

8. What is

9. Virtualization

10. "In computing, virtualization refers to the act of
creating a virtual (rather than actual) version of
something, including virtual computer hardware
platforms, operating systems, storage devices,
and computer resources."

11. "Virtualization software makes it possible to run
multiple operating systems and multiple applications
on the same server at the same time”

14. Pros and Cons of Virtualization
Pros:
• Isolate applications
• Reduced number of physical servers
• Reduced costs
• Full utilization of the server resources
• Fundamental technology that powers Cloud
Computing
• Increases application uptime by running on diff
physical server
Cons:
• It takes 2-3 minutes to provision a VM.

15. Containers

17. Operating-system-level virtualization is a
server virtualization method in which the kernel of
an operating system allows the existence of multiple
isolated user-space instances, instead of just one.
Such instances, which are sometimes
called containers, software containers, virtualization
engines (VEs), may look and feel like a real server
from the point of view of its owners and users.

19. Some benefits of Using Containers
• They have a very little footprint
• They can be deployed very fast (within milliseconds)
• They can run on any computer, infrastructure, or cloud
environment
• Containers use less memory and CPU than VMs running
similar workloads
• Increased productivity with reduced overhead

20. Some of the Drawbacks
• Containers are ephemeral
• Difficult to manage

21. In 2013, Docker was founded

24. Google’s Adoption of
Containers

25. In 2014
“Everything at Google runs in Containers”
“There were 2 billion new containers being deployed
every week at Google”

28. The Go Programming Language

29. About Golang
• Relatively new programming language
• Developed internally at Google in 2009
• Rich support for concurrency
• Ability of code reusability through packages
• Most popular language in Cloud Computing
• Docker is built with Golang!
• Light weight
• Easy to comprehend and develop
• By 2020, more than 500,000 Gophers!

30. Open Source Golang Projects
• Docker – The best project in Golang
• Anything built on top of Docker
– Kubernetes (Google’s tool)
• Gogs (Go Git Service) – Your own github!
