Level Set: What is the cloud?
Getting Hands-on: Build a Static Website on AWS.
Powerful Tools to Research Next
Passing the Interview
Feel comfortable exploring/developing in the Cloud!
Today's Goals
Agenda
What is Cloud Computing?
- network of remote servers hosted via the internet providing services to clients
What's a server?
A powerful computer (usually rack mounted), that is monitor-less. You must connect remotely.
A server in the cloud...
Someone else managing the physical servers on location and you using its services via the internet
Who are the cloud providers?
What is Cloud Computing?
- three distinct types of computing services delivered remotely to clients via the internet.
Infrastructure as a Service (IAAS)
- Allows end users to remotely use hardware and resources via the web on a pay as you go basis
Platform as a Service (PAAS)
- Allows end users to publish and develop software applications to an environment hosted via the web
Software as a Service (SAAS)
- Allows end users to use software applications via their web browsers
How does the cloud impact business?
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
Lab from: https://github.com/aws-samples/aws-serverless-workshops/tree/master/WebApplication/1_StaticWebHosting
Non-Functional Requirements?

Regions vs Availability Zones
Region
Separate geographical area
Ex: California & Oregon (US West Regions)
Availability Zone (AZ)
Isolated location within a region
How might this help businesses?
Architecture Diagram
Select Your Region
1. Create an S3 bucket
Simple Storage Service
- 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
Add in website content. Download from S3.
(s3Bucket: aws-lab-materials)
2. Upload content
define who can access the content in your S3 buckets using a bucket policy
3. Add a bucket policy
Bucket Policy
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
}
]
}
Enable access to index.hmtl via url
4. Enable Website Hosting
Check out our app!
The site is from aws-samples github organization.
Recap of What we Built
- S3 bucket
- Bucket Policy
Now delete it all :)
Other Cloud Technology
- Microsoft Azure
- Google Cloud Platform
- IBM Cloud
- Rackspace
More Cool Stuff to Check Out
- Other AWS Resources
- AWS CLI
- Cloud formation templates
- Chef
- Ansible
- Docker
- Jenkins
- Terraform
Pass the Interview!
Can anyone think of use cases for resources we didnt use?
Explain the difference between cloud and traditional datacenters.
- No physical hardware you manage with the cloud
- Inexpensive
- Quick scalability
- Start up friendly
- Pay as you go
What are the layers of cloud computing?
- Infrastructure as a Service
- Platform as a Service
- Software as a Service
Describe the difference between
Scalability & Elasticity.
Elasticity
- The ability to fit the resources 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
Which of the following resources is best for storing transactional and relational data
A) S3
B) Dynamo DB
C) RDS
E) All of the above
Describe a region vs an availability zone?
A region is a separate geographic area. A region has many isolated locations known as availability zones.
