What is Cloud Computing?

  • Network of Remote Servers
  • Platform to help build scalable applications
  • Fast access to low cost resources over the internet

What are the benefits?

  • Cost!  Pay for infrastructure as needed
  • Scale up to balance load
  • Low risk- great for experiments (hello start-up)
  • Deploy applications in multiple regions

Which is why so many companies run on AWS!

So Let's Deploy Our Website on AWS too

Non-Functional Requirements?

Security!

Make a Key Pair

Kind of like password to log into the EC2.

Create Security Group

Firewall controlling traffic around the application.

Create Security Group #2

This controlls traffic around the database.

Check-in:  All Good?

Elastic Compute Cloud (EC2)

Start the Webserver

sudo yum update -y
sudo yum install -y httpd php mysql
sudo service httpd start
sudo chkconfig httpd on

Add these lines to your User Data section.

Amazon Machine Image

AMIs give the baseline set-up for EC2 instances.

You can customize AMIs to include encryption, resource configurations, and software updates.

 

Check-in:  All Good?

Configure the Database

RDS Instance:  Relational Database Service

Create RDS Instance

Automagically makes replica in another availability zone.

  • Relational Database
  • Resizable capacity
  • MySQL, PostgreSQL, etc.
  • Object Storage
  • Pay for storage use
  • Glacier for long-term archive
  • Good for big data analytics, backup, and other applications

S3

RDS

Check-in:  All Good?

Auto Scaling Group

Launch or terminate EC2 instances based off of policy.

  • Maintain application performance by adding and removing EC2s based on CPU, requests, time of day
  • Decrease cost by "turning off the lights"
  • Cross region availability

Launch Configuration

Template for the auto scaling group.

  1. Choose My AMIs:  summit
  2. Follow Configure Details
  3. Select our app Security Group
#!bin/bash
yum update -y
service httpd start
chkconfig httpd on

Auto Scaling Group

Make sure to select our Security Group!

Set TCP for Health Check

Recap of What we Built

  • EC2
  • Security Groups
  • Key Pairs
  • AMI
  • RDS
  • SNS
  • Launch Config
  • Autoscaling Group

Now delete it all :)

Pass the Interview! 

 

Can anyone think of use cases for resources we didnt use?

What are the layers of cloud computing?

Infrastructure as a Service 

 IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems.

What are the layers of cloud computing?

Platform as a Service

PaaS is the set of tools and services designed to make coding and deploying applications quick and efficient.
 

What are the layers of cloud computing?

Software as a Service 

 SaaS applications are designed for end-users, delivered over the web via third party vendors.

Describe the difference between

Scalability & Elasticity.

Elasticity         

  • The ability to fit the resoures with needs of your system to cope with the demand dynamically. 
  • ie -The ability to scale up and down appropriately

Scalability 

  • Ability of your system to add more resources to accommodate larger work loads

Learn More and Get Certified

  • AWS qwiklabs 
  • Cloud Academy

AWS offers several different certification you can take to show companies how awesome you are in the cloud! 

 

Thanks!
