• Introduction
  
• Resizeable compute instances in cloud
• Can be provision one and more instances
• Pay for what you use: no minimum fare
• Kind of instances
• Family
• Micro-instance, CPU, Memory, Storage-optimized
• Type
• t1.micro, m2.xlarge, c3.large....
• Recent instances
• High capable - hl1 (120,000 random read IOPS-ssd)
• Large storage- hs1 (48TB storage per instance)
• Large memory- cr1 (244 GB RAM)
  

• Elastic
• Scale as required and reduce costs
  
• Reliable
• Elastic load blancer, auto scaling and mutiple AZone
  
• Completed controlled
• fully managed by console and APIs to all instances
  
• Secure
• Many certifications for security, privace and procedures 
• Virtual Private Cloud is default
  
• Flexible
• Choose mutiple instance types and pre-made instances
  
• Inexpensive
• Cost model: on-demand, reserved and spot instances
  

• Sign-up AWS account
• Go to EC2 Dashboard
• Launch Instance
• Choose Amazon Machine Images(AMI)
• Hypervisor: hvm or paravirtual
• Various OS: Windows/Linux
• Setup of VPC, IAM and NIC
  
• Choose Elastic Block Storage
• Choose Security settings both in-out bounds
  
• Connect to the instance via SSH

 ssh -i channy.pem ec2-user@54.179.188.138

• Attach volume and register volume /etc/fstab
  

$ ls -al /dev/xvd*
$ sudo mkfs.ext4 /dev/xvdf
$ sudo mkdir /files
$ sudo mount /dev/xvdf /files

• Configure your web servers

$ sudo /sbin/chkconfig --add httpd 
$ sudo /sbin/chkconfig httpd on
...
$  /etc/sysconfig/iptables stop

• Cost Model for Instances
• Reserved instances: very cheap for 1~ 3 years
  
• Spot instances: can be cost-effective bidding 
• Share Images
• You can make own AMIs and share them
