Lab Details
This lab will walk you through the steps needed to create and configure a virtual machine on Amazon's cloud.
You will use Amazon Machine Images to launch Amazon EC2 Instances. To log into your instance, you will need key pairs for SSH authentication. You will create a website and publish it.
Duration: 60 minutes
AWS Region: US East, N. Virginia us-east-1
Introduction
What is EC2?
AWS refers to it as Elastic Compute cloud.
It's a virtual world that you can rent to create your environment, without having to purchase.
These virtual machines are known as Instances by Amazon.
You can use pre-configured templates to launch instances. These templates are known as images. These images are available from Amazon in the form AMIs (Amazon Machine Images).
Allows you install custom applications and services.
It is simple to scale infrastructure, i.e. up or down depending on the demand.
AWS offers multiple configurations of storage, memory, and CPU. You can choose the flavor that suits your environment.
There is no limit to storage. You can choose the storage that is most appropriate for the type of instance you are working on.
Instance Store Volumes are temporary storage volumes. This data is deleted when the instance ends.
There are persistent storage volumes available. They are known as EBS (Elastic Block Store).
These instances can be placed in multiple locations, which are called Regions and Availability Zones.
Your Instances can be distributed across multiple AZs, i.e. within a single Region. If an instance fails, AWS will automatically remap the address to another AAZ.
It is possible to migrate instances from one AZ to another.
You can optionally assign your own metadata for each resource, such as tags, to manage instances, images and other EC2 resources.
A tag is a label you assign to an AWS resource. It can contain a key and an optional number, which you can define.
Each AWS account comes standard with a set default limits for the resources, which are determined per-Region.
AWS is required to inform you if the limit is increased.
Key pairs are used to work with the instances that have been created.
