INTRODUCTION AND HISTORY

CLOUD COMPUTING

• Cloud computing is the delivery of on-demand computing services.

WHAT IS CLOUD COMPUTING

• Rather than owning their own computing infrastructure or data centers, companies can rent access to anything.

• One benefit of using cloud computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it.

• From applications to storage and processing power typically over the internet and on a pay-as-you-go basis.

VIRTUAL MACHINES

WHAT IS VIRTUAL MACHINES

• A virtual machine, known as a guest, is created within a computing environment, called a host.

• In other words, virtual machines behave as separate computer systems.

• Virtual machines are software computers that provide the same functionality as physical computers.

WHY VIRTUAL MACHINES

• Virtual machines are created to perform specific tasks that are risky to perform in a host environment.

• The software inside the virtual machine cannot tamper with the host computer.

BENEFITS OF VIRTUAL MACHINE

LET'S SEE AN VIRTUAL MACHINE

VIRTUAL MACHINE ARCHITECTURE

VIRTUAL MACHINE SOFTWARES

CONTAINERS

WHAT IS CONTAINER

• A Container in cloud computing is an approach to operating system virtualization.

• By this, the user can work with a program and its dependencies using resource procedures that are isolated.

• The code of the application can be bundled with configurations and dependencies in a systematic manner.

• Container in cloud computing is used to build blocks, which help in producing operational efficiency, version control, developer productivity and environmental consistency.

WHAT IS CONTAINERIZATION

• The use of containers to deploy applications is called as containerization.

ADVANTAGES OF CONTAINER

Containerization is increasingly popular because containers are :

1. Flexible ,

2. Light Weight ,

3. Portable ,

4. Loosely Coupled ,

5. Scable and

6. Secure

CONTAINER FOR ENVIRONMENT CONSISTENCY

DOCKER CONTAINERS

WHAT IS DOCKER

• Docker is a platform for developers to build, run, and share applications with containers.

• Fundamentally, a container is nothing but a running process, with some added encapsulation features applied to it in order to keep it isolated from the host and from other containers.

IMAGE & CONTAINER

• An image includes everything needed to run an application - the code or binary, runtimes, dependencies.

• Above is the image of cat (docker image) what if cat get out of this image and say Hi (docker container)

DOCKER HUB

• You can find images from DockerHub.

• See hello world image from DockerHub.

• Then you run container from that image.

  LETS START DIGGING 

• I hope you guy's have already installed Docker on your system.

• Let's run our first container.

• Don't Use Docker Toolbox please , it is depreciated.

CONTAINER ORCHESTRATION

CONTAINER ORCHESTRATION

• Container orchestration is the automatic process of managing or scheduling the work of individual containers for applications based on microservices within multiple clusters.

• The widely deployed container orchestration platforms are based on open-source versions like Docker Swarm.

• The word orchestration is dervied from orchestra.

• Container orchestration has helped to achieve microservices and microfrontend architecture.

UNIKERNELS

UNIKERNELS

• Unikernels are specialized, single-address-space machine images constructed by using library operating systems.

• Unikernels are library operating systems this means that they are very lightweight operating systems and secure they are not like containers (especially docker) they are the very lightweight sizes of few MB's.

ADVANTAGES OF UNIKERNEL

• Unikernels are great and lightweight here is a few advantages which given below:

Improved security, Small footprints, Highly optimized, Fast Boot

PROJECTS OF UNIKERNEL

• Runtime.js: An open-source library operating system for the cloud that runs JavaScript

• Unik: UniK (pronounced you-neek) is a tool for simplifying compilation and orchestration of Unikernels.

• IncludeOS: A minimal, service-oriented, include able library operating system for cloud services. Currently a research project for running C++ code on virtual hardware.

If you want to dig into other projects for your use case then go through this link: http://unikernel.org/projects/
