• Shed unneeded Amazon EC2 instances au<strong>to</strong>matically and save money when demand<br />

subsides.<br />

• Scale dynamically based on Amazon CloudWatch metrics, or predictably according <strong>to</strong> a<br />

schedule that cus<strong>to</strong>mers define.<br />

• Receive notifications via Amazon Simple Notification Service (SNS) <strong>to</strong> be alerted when<br />

you use Amazon CloudWatch alarms <strong>to</strong> initiate Au<strong>to</strong> Scaling actions, or when Au<strong>to</strong><br />

Scaling completes an action.<br />

• Run On-Demand or Spot instances, including those inside your Virtual Private Cloud<br />

(VPC) or High Performance Computing (HPC) Clusters.<br />

• Au<strong>to</strong> Scaling is enabled by Amazon CloudWatch and carries no additional fees.<br />

Elastic Load Balancing au<strong>to</strong>matically distributes incoming application traffic across<br />

multiple Amazon EC2 instances. It enables Region 14 and <strong>NCPA</strong> members <strong>to</strong> achieve<br />

even greater fault <strong>to</strong>lerance in their applications, seamlessly providing the amount of<br />

load balancing capacity needed in response <strong>to</strong> incoming application traffic. Elastic<br />

Load Balancing detects unhealthy instances within a pool and au<strong>to</strong>matically reroutes<br />

traffic <strong>to</strong> healthy instances until the unhealthy instances have been res<strong>to</strong>red. Cus<strong>to</strong>mers<br />

can enable Elastic Load Balancing within a single Availability Zone or across multiple<br />

zones for even more consistent application performance. Elastic Load Balancing can<br />

also be used in an Amazon Virtual Private Cloud (VPC) <strong>to</strong> distribute traffic between<br />

application tiers. Key features include:<br />

• Distributing incoming traffic across Amazon EC2 instances in a single Availability Zone<br />

or multiple Availability Zones. Elastic Load Balancing au<strong>to</strong>matically scales its request<br />

handling capacity in response <strong>to</strong> incoming application traffic.<br />

• When used in a VPC, users can create and manage security groups associated with their<br />

Elastic Load Balancing <strong>to</strong> provide additional networking and security options.<br />

• When used in a VPC, users can create a load balancer without public IP addresses <strong>to</strong><br />

serve as an internal (non-Internet facing) load balancer.<br />

• Elastic Load Balancing can detect the health of Amazon EC2 instances. When it detects<br />

unhealthy load-balanced Amazon EC2 instances, it no longer routes traffic <strong>to</strong> those<br />

Amazon EC2 instances and spreads the load across the remaining healthy Amazon EC2<br />

instances.<br />

• Elastic Load Balancing supports the ability <strong>to</strong> stick user sessions <strong>to</strong> specific EC2<br />

instances.<br />

• Elastic Load Balancing supports SSL termination at the Load Balancer, including<br />

offloading SSL decryption from application instances, centralized management of SSL<br />

certificates, and encryption <strong>to</strong> backend instances with optional public key authentication.<br />

• Flexible cipher support allows users <strong>to</strong> control the ciphers and pro<strong>to</strong>cols that are accepted<br />

by Elastic Load Balancing in the SSL negotiation for client connections.
