Cloud Computing

"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."

What is

Virtualization

"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."

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

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.

Containers

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.

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

Some of the Drawbacks

• Containers are ephemeral• Difficult to manage

In 2013, Docker was founded

Google’s Adoption of Containers

In 2014

“Everything at Google runs in Containers”

“There were 2 billion new containers being deployed every week at Google”

The Go Programming Language

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!

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!
