Elastic Beanstalk
• Supports common platforms:
• Java, Ruby, Python, PHP, Node.js, .Net
• Automatic deployment; upload and go.
• No infrastructure planning needed; handles: load
balancing, virtual machines, databases,
monitoring, etc.
• Resources are automatically allocated
• Scales automatically (horizontally)
Free tier
• Includes most of the AWS services
• Available for all new account
• Good for one year from the day the account is created
• Everything we show today can be done within the free
tier
• More details at http://aws.amazon.com/free
FREE
Let’s Get Started:
We’ll learn how to: – Set up an AWS account
– Create your SSH keys (used to log into your instances)
– Create a security group (firewall)
– Start an EC2 instance (virtual machine)
– Connect to your EC2 instance
– Create a CloudWatch alarm to email you if your server is under heavy load
– Take a snapshot (backup) of your instance and restore it
– Use S3 (Internet connected storage)
Sign Up
• Sign up though https://aws.amazon.com
• You need a CC
• There will be a phone verification
Demo Signing Up for AWS
Creating your SSH Key
• SSH stands for Secure Shell
• SSH keys are used for secured access to EC2 (Linux)
• SSH keys avoid password weaknesses
• Can import your own or use AWS created keys
Demo Creating SSH Keys
Creating a Security Group
• Security Groups are firewalls for your instances
• By default, the Security Group blocks everything
• Choose which protocols & ports are open – Can use port ranges (e.g. 22-24)
• Choose which addresses the ports are open to – Uses CIDR rules for IP address access
– (use /32 for allowing a single address)
Demo Creating a Security Group
Start a New Instance
• Instances are virtual machines running in the cloud
• You have full control of the instance and can install
any software that you choose
• In this process, you define what kind of machine you
want (processing power, HD space, etc.)
• You will need: – A Key Pair to connect to your instance via SSH
– A Security Group to put your instance in
Demo Starting an EC2 Instance
Select Choose one or more of your existing Security groups
Connecting to EC2 Instances
• SSH is used to connect to Linux – There is a Java-based terminal available in the EC2 Console
– Linux/OSX: Terminal
– Windows: PuTTY
– Note: If you are using an Linux distribution that has a GUI, you can use a remote GUI tool like VNC
• Remote Desktop is used to connect to Windows – Windows: MSTSC (Microsoft Terminal Services Client)
– Linux/OSX: 2X client
– Note: you can also use Remote PowerShell or a 3rd party shell extension with Windows.
Connecting to a Linux Instance (from Linux/OSX)
• Open a terminal window
• ssh -i {ssh private key location} ec2-
user@{public DNS name}
Connecting to a Linux Instance (from Windows)
• Download/Install PuTTY – http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
• Convert .pem file to .ppk with puttygen
• Create a connection in PuTTY
Connecting to a Windows Instance (from Windows)
• Open a Remote Desktop connection
• Windows + r or start and then the “run” option
• mstsc /v:{EC2 instance public DNS Name}

CloudWatch
• CloudWatch provides monitoring information for your EC2 instances
• CloudWatch allows you to specify actions to take when a condition is met – Example 1: Send an email when CPU Utilization >80% for 5
minutes
– Example 2: Add another machine to an Auto-Scaling Group if Average Disk Read IOPS across an Auto-Scaling Group exceeds 500
– Example 3: Remove a machine from an Auto-Scaling Group if Network input drops below 2,000 Bytes
Demo Creating a CloudWatch Alarm
Additional Information
• CloudWatch works with Auto-Scaling
• When you have defined an Auto-Scaling Group,
CloudWatch Alarms can be used to increase
and decrease the resources in the Auto-Scaling
Group.
Elastic Block Storage
• Elastic Block Storage (EBS) is block level
storage for EC2 instances (think HDD)
• EBS volumes can be removed and re-attached
• Custom volume sizes from 1TB – 1 GB (RAID
for larger)
• Use Provisioned IOPS for predictable I/O
Demo Backing up an EBS volume
Restoring a Snapshot / Creating an AMI
• AMIs are Amazon Machine Images
• AMIs are bootable versions of a snapshot (backup)
• AMIs are private, but you can choose to share them
with others
Demo Creating an AMI / Restoring a Snapshot
S3
• S3 is Amazon’s Simple Storage Service
• Store and retrieve almost any amount of data – 1 Byte to 5 Terabytes
• Highly scalable
• Highly durable – Regular S3 has 99.999999999% durability
– Reduced Redundancy Storage (RRS) offers 99.99% durability at discount
• Encryption available – At rest and for ingest/delivery
• Storage is isolated by region
• Object level permissions
• Easily Accessible – Web (HTTP/HTTPS)
– P2P (BitTorrent)
– APIs (REST & SOAP)
Demo Using S3
Summary
• We covered: – Signing up (and in) with AWS
– Creating SSH Keys (not needed for Windows)
– Configuring a Security Group (setting firewall rules)
– Creating an EC2 instance
– Connecting to an EC2 instance
– Creating a snapshot of your instance (Taking a backup)
– Restoring a snapshot of your instance (Creating an AMI)
– Setting a CloudWatch Alarm
– Creating an S3 bucket, uploading a file, & making the file public
