Introduction to Cloud Computing
• Cloud computing is the delivery of on-demand
computing resources (including servers,
databases, storage, platforms, infrastructure,
applications, etc.) over the Internet.

Advantages of Cloud Computing
• Cost-Efficiency
– The Total cost of ownership(TCO),Upfront cost for starting a
business is reduced.
• Scalability & Speed
– Scale the resource in and out
• Unlimited Storage Space
– Storage can be reduced and increased based on need
• Backup & Recovery
– Using snapshot for backup at any time
• Go Global in Minutes
– Create and deploy the application within minutes

Cloud Computing Services

Alibaba Cloud
• Alibaba Cloud, is a cloud computing company, a
subsidiary of Alibaba Group.
• Alibaba Cloud provides cloud computing
services to online businesses and Alibaba's own
e-commerce ecosystem.
• Alibaba Cloud's international operations are
registered and headquartered in Singapore
• Alibaba Cloud Ranked No.1 by Gartner in Asia
Pacific region and 5 th in world wide

Alibaba Cloud Global Infrastructure
• Alibaba Cloud's infrastructure is built around
regions and zones (availability zones).
• Region refers to a physical node on a global scale.
• Each region is composed of multiple zones.
• Alibaba Cloud regions are physical locations (data
centers) that spread all over the world to reduce
the network latency.
• A zone is composed of one or multiple scattered
data centers, each of which has independent
supporting facilities including redundant power
supplies, networks, and connections.

Power of Alibaba Cloud-Double 11 festival
• For Double 11 Online Shopping Festival,the whole
infrastructure for the festival is provided by alibaba
cloud
• Various scenarios achieved are
– Processing of $1 billion in gross merchandise volume (GMV)
in the first 68 seconds of the shopping event
– Totally $38.4 billion of GMV in 24 hours with zero downtime.
– 970 perabytes of data to support the peak performance of
544,000 orders per second
– 87 million requests processed per second
– the machine translation service was used 1.66 billion times,
with over 200 billion words translated in different
languages(21 languages)

Alibaba Cloud Pricing Model
• Pay-As-You-Go
– Pay-as-you-go instances are charged based on usage, and no up-front
payment is required.
– You can scale resources according to your business needs
• Subscription
– Subscription instances have a lower price point when compared with pay-
as-you-go instances, and enable you to reserve resources. Subscription
instances are ideal for users who require a large number of resources for
the long term
• Preemptible Instance
– preemptible instances allow you to request spare ECS resources for a
significant cost reduction. When you create a preemptible instance, you
can set the highest hourly price to bid for a specified instance type. If your
bid is higher than the current market price, your instance is created and
billed based on the current market price

• Software Development Life Cycle (SDLC)
– It is a process used by the software industry to
design, develop and test high-quality software.
Traditional Software Development

Water Fall Model

Agile Software Methodology
• It focus on customer satisfaction by rapid
delivery of working software product.
• Agile Methods break the product into small
incremental builds.
• These builds are provided in iterations.
• Each iteration typically lasts from about one to
three weeks.
•

Agile Software Methodology
• Every iteration consist of following process
– Planning
– Requirements Analysis
– Design
– Coding
– Unit Testing and
– Acceptance Testing.

Downfall of Traditional S/W development
• “Black boxes” to Developer and operation team
leads to finger-point
• Long time to market because deployment
changes take a long time.
• It take a long time to identify and fix the
problem.
• Lack of automation leads to non-consistency in
build and deployment.

DevOps Introduction
• DevOps=Dev(Development) + Ops(Operation)
• DevOps is a Software engineering culture and
practice that aims at unifying software
development(Dev) and software operation(Ops)
• It is a culture of collaboration between
developers and operation people
• Dev and ops work together and share a
common goal

DevOps Introduction

Advantages of DevOps
• New features can be implemented immediately
• It bring developer and operators close together.
• It ensure consistency between development
and production environment, which reduce
error and increase speed
• It consists of a set of technology and tools to
automate project development.
• It automate the testing and development task.
• It improve stability and deployment time for the
new feature

DevOps Automation Tools
• Various Automation tools used are
– Github
– Terraform
– Chief
– Ansible
– Packer
– Jenking
– Docker
– Kubernetes

Source code Management -Github
• It is code storage and management tool used
for speed delivery of code.
• Advantages of Github
– It makes it easy to contribute to your open source
projects
– GitHub can be used as a repository for the project
source code.
– Track changes in your code across versions
– It has Integration options with All Cloud Providers

Configuration & Provisioning Tools
• Provisioning Tools:
– It can be used to provision the infrastructure
components such as servers, load balancers,
databases, networking devices.
– Eg) Terraform
• Configuration Tools:
– It is used to install and manage software on existing
servers in the infrastructure
– various Tools present are Chef,Ansible,puppet.

Continuous Integration and Delivery-
Jenkins
• Continuous Integration is used to integrate code
from the shared repository at regular intervals. .
• Jenkins is a powerful application that allows
continuous integration and continuous delivery
of projects.
• It is a free source that can handle any kind of
build or continuous integration

Containerization - Docker
• Container: It allows the developer to package
up an application with all of the part needed to
run an application such as class libraries and
external references.
• Docker is a container management service.
• The keywords of Docker are develop, ship and
run anywhere.
• It is used to develop applications, ship them into
containers which can then be deployed
anywhere. 24Gavaskar S,MVP at Alibaba Cloud|gavaskar@dingtalk.com

Container monitoring-Kubernetes
• Kubernetes is a container management
technology developed in Google lab
• It is used for orchestration of the container
created.
• Advantages of Kubernetes
– Environment consistency across development
testing and production
– Loosely coupled infrastructure, where each
component can act as a separate unit

Kubernetes-Architecture

Alibaba Container Service for Kubernetes(ACK)
• Alibaba Cloud Container Service for
Kubernetes(ACK) is container management
service, provided by Alibaba Cloud
• •It is used to manage the entire lifecycle of
containerized applications
• •Container Service for Kubernetes provides an
ideal runtime environment for Kubernetes
based containerized application

Alibaba Container Service for Kubernetes(ACK)
• Three types of Kubernetes clusters supported
are
– Dedicated Kubernetes cluster
• master node and worker node has to be created by user
– Managed Kubernetes cluster
• user has to create worker node alone
– Serverless Kubernetes
• user did not want to create master node or worker node

Account Creation & Alibaba
Container Service for Kubernetes
Demo

Demo-1 Scenario
• •Cluster creation->kubernets-demo
• Node creation->3 worker node and 3 Master node
• Creating container with image “nginx” and replica
set=1 and deploy in the pod(automatically created)
• Deletion of the pod->not deleted since the minimum
replica is 1
• Change the replica from 1 to 3 and assigning
deployment object->nginx
• Change the replica from 3 to 1 and assigning
deployment object->nginx
• Delete deployment.

Demo-2-Implementing Web server Scenario
• Creating container with image “nginx” and
replica set=2,port=80 and deploy in the
pod(automatically created)
• Create a service with port 8080,deployment
object->nginx,target port->80 and set
loadbalancer option
