IaaS Server as a Service Storage as a Service Network as a Service
3
We have created an EC2 instance (Server as a Service)
We have attached an EBS volume to the instance (Storage as a Service) We have installed a web server on the EC2 instance
4
If the EC2 instance terminates, we can create another instance, and attach the EBS volume to the new instance (data are persistant) But the IP address of the instance is not persistant! - you have to reconfigure the clients that rount to the server via IP - update your DNS server and wait for it to propagate We can address this inconvience by using Amazon Elastic IP Address (Network as a Service)

Elastic IP Address Different types of IP addresses for EC2 instances
- EC2 Private IP address: the private IP address is only routable within the EC2 cloud. - EC2 Public IP address: Internet routable address assigned to each EC2 instance. example: - EC2 Elastic IP address: Internet routable address allocated to an AWS EC2 account. But you can associate an Elastic IP addres to an EC2 instance.

Elastic IP Address
8
Each AWS account is allowed to have 5 elastic IP addresses (If you requires more than 5, you need to apply for it) If you create an Elastic IP address without associating it with an instance, you will be charged $0.01 per hour.

Demo how to use Elastic IP address
Once you associate an elastic IP address with an EC2 instance, the original public IP address of the instance will be released.

The benefits of Amazon CloudFront - reduce the network latency – nearest edge location - take off the load of your server - large number of requests can be processed simultaneously – from edge locations - Increase customer experience - Enable mobile clients - Protection of your content via redundancy – content copied to multiple edge locations
