AWS provides cost allocation tags to categorize and track the AWS costs. When the user applies tags to his AWS resources, AWS generates a cost allocation report as a comma-separated value (CSV file. with the usage and costs aggregated by those tags. Each tag will have a key-value and can be applied to services, such as EC2, S3, RDS, EMR, etc. It is required that the key should be different for each tag. The value can be the same for different keys. In this case since the value is different, AWS will properly show the distribution report with the correct values.

The terminology and concepts that are central to one's understanding and use of Amazon Cloud-Watch are as follows: metrics, namespaces, dimensions, timestamps, units, statistics, periods, aggre-gation, alarms, and regions.Reference:http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html

Security Groups in VPC operate at the instance level, providing a way to control the incoming and outgoing instance traffic. In contrast, network ACLs operate at the subnet level, providing a way to control the traffic that flows through the subnets of your VPC.Reference:http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Security.html

AWS Cloudwatch can be accessed from the Amazon CloudWatch Console, CloudWatch API, AWS CLI and AWS SDKs.Reference:http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/accessing_cloudwatch.html

You can organize and manage your Auto Scaling groups by assigning your own metadata to each group in the form of tags. You specify a key and a value for each tag. A key can be a general cate-gory, such as "project", "owner", or "environment", with specific associated values.By default, the instance will have a tag with the key as "aws:autoscaling:groupName" and the value as the name of the group.Reference:http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/ASTagging.html

Auto Scaling is well suited to both applications that have stable demand patterns and that experi-ence hourly, daily, or weekly variability in usage. Whether the demand is predictable or unpredicta-ble auto scaling can be a good choice. If the demand is predictable and long term you may choose reserved instances. If the demand is unpredictable you may choose on-demand or even spot instance (if you can afford to have an instance lost unexpectedly).Reference:http://aws.amazon.com/autoscaling/

AWS Import/Export accelerates transferring large amounts of data between the AWS cloud and portable storage devices that you mail to us. AWS transfers data directly onto and off of your stor-age devices using Amazon high-speed internal network.Reference:http://docs.aws.amazon.com/AWSImportExport/latest/DG/whatisIE.html

By default, a load balancer routes each request independently to the registered instance with the smallest load. However, you can use the sticky session feature(also known as session affinity), which enables the load balancer to bind a user's session to a specific instance. This ensures that all requests from the user during the session are sent to the same instance.Reference:http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-sticky-sessions.html

Amazon EC2 provides virtual computing environments known as instances. When you launch an instance, the instance type that you specify determines the hardware of the host computer used for your instance. Each instance type offers different compute, memory, and storage capabilities and are grouped in instance families based on these capabilities. Select an instance type based on the re-quirements of the application or software that you plan to run on your instance.Reference:http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/concepts.html

A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. A user can create a subnet with VPC and launch instances inside that subnet. If the user has created two subnets (one private and one public., he would need a Network Address Translation (NAT) instance with the elastic IP address. This enables the instances in the private subnet to send requests to the Internet (for example, to perform software updates).
