Lab Details
This lab will show you how to create and configure an EC2 Instance with OpenVPN AMI. It also shows you how to connect to the VPN.
OpenVPN Amazon Machine Images will be used to practice launching Amazon EC2 Instances.
Duration: 60 minutes
AWS Region: US East, N. Virginia us-east-1
Introduction
What is an EC2?
AWS refers to it as Elastic Compute cloud.
You can rent a virtual environment to create your own environment, and it's free.
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).
This allows you to create custom applications and services.
It is simple to scale infrastructure, i.e. up or down depending on your demand.
AWS offers multiple configurations of storage, CPU, memory, and other options. You can choose the flavor that is best for you.
There is no limit to storage. The type of instance you are working with will determine the storage that you choose.
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 volumes (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 one 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 assign your own metadata to each resource, such as tags, in order to manage instances, images and other EC2 resources.
A tag is a label you give to an AWS resource. It can contain a key or an optional value. Both of these are set by you.
AWS accounts come with default resources limits that are per-Region.
AWS is required to inform you if the limit is increased.
Key pairs are used to work with created instances.
