Cloud Services Event

Introduction to the Amazon Web Services

By

Nanyak Loknan S.
@nanyaks
This presentation aims to give an overview of what the Amazon Web Services is and why people are adopting it.
I'll be sure to make some time for questions

Introduction

The Amazon Web Services is a collection of remote computing services that together make up a cloud computing platform offered over the internet by Amazon.
It aims to enable businesses and developers to use Web Services to build and easily deploy scalable, sophisticated systems.

Why should I care?

Variable Expense
Save costs by paying only for what you use. No upfront payments and freedom to opt out
Standard and Highly Available Computing units
Using the AWS, you have access to the same Infrastructure that powers all Amazon technology.
Elastic Capacity
No need to guess capacity requirements and over provision hardware
Speed of Deployment
Get Infrastructure deployed and production ready in minutes and not in weeks
Focus on your Business
You don't have to worry about the intricacies of building a data center.

Reference Model

AWS Global Infrastructure

  • Regions
  • Availability Zones
  • Edge Locations

Networking Services

Direct Connect

AWS provides a direct connection between your IT infrastructure and the AWS data centers.

With this, you can extend your VLANs and privately facing infrastructure into the AWS/Cloud
VPN

AWS provides you the ability to create your own VLAN on the Amazon Infrastructure and have a VPN connection across the internet.

Virtual Cloud

Create an isolated network off a section of the AWS Cloud where you can launch resources and have complete control over your networking environment

  • Route 53

    Highly available and scalable Domain Name System that is extremely reliable and cost effective.

    This is a global DNS Service that gives 100% request-reply guarantee.

Elastic Compute Cloud

Total of 23 Instance types available .
Range from very small ( micro instances ) to very large computation ( cluster compute ) instances.
Run windows or linux instances
Save your configurations as custom image types (AMI) from which other machines can be launched.
You have full control of your instance
You can publish metrics to cloudwatch and have detailed stats on instance health

Auto Scaling

Allows automatic re-sizing of compute clusters based on demand
Allows you to define minimum and maximum instance pool size for when scaling up or down is needed
Uses metrics gathered by Cloudwatch to drive the scaling

Load Balancing

Distribute load across instances in multiple availability zones
The Elastic Load balancer allows you to create highly scalable applications on the Amazon Cloud.
It automatically checks the health of instances and takes them in or out of service
Session Stickiness
The load balancer routes requests to the same instance when a session is started on that instance.

Simple Storage Service (S3)

An object storage platform that acts as a fundamental bedrock of many applications
Unlimited storage of any type of data upto 5TB in size

Elastic Block Storage (EBS)

This is a high performance block storage device that can be mounted as drives on instances
With flexible sizes, you have more than enough space for your application environment
The EBS volume is private to your instance
The operating system of an instance resides on the EBS volume and any launched instance will boot from this drive
Integrates with snapshotting features
Snapshots of the EBS volumes can be taken for point in time restore or even used to launch another instance.

Relational Database Service (RDS)

Provides Database-as-a-service
Managing a production database can be a real pain, RDS alleviates this for you.
Easily launch scalable and fault tolerant Mysql, Oracle or SQL Server databases
Like the EC2, the RDS allows you to launch instances based on classes (ie. micro, small, medium, large etc)

CloudFront

This serves as a Content Delivery Network for static assets on the AWS stack.
Easily distibute content to your users with low latency and high data transfer speeds.

Elastic Beanstalk

Rapidly deploy your applications to the Amazon Cloud.
The Elastic Beanstalk allows automatic creation of application environment and proceeds with application deployment.

Nginx

Nginx is a fast and very flexible HTTP and Reverse Proxy Server built by Igor Sysoev in 2002.

The project started with a strong focus on high concurrency, high performance and a low memory footprint

Basic Features

Nginx does a lot of the functions of a regular Web server and is excellent as a reverse proxy sitiing on your network.

  • Serving static content
  • Reverse proxying and caching
  • Simple load balancing and fault tolerance
  • Reconfiguration and upgrade of the nginx executable without a server restart
  • Customizable access log formats
  • Easily execute functions based on client addresses
  • Media Streaming
  • ... and many more

Thank you!
