Before you can delete a VPC, you must terminate any instances that are running in the VPC.

In the previous step, you launched your instance into a public subnet — a subnet that has a route to an Internet gateway. However, the instance in your subnet also needs a public IP address to be able to communicate with the Internet.
When you launch an EC2 instance into a VPC, you must specify the subnet in which to launch the instance. In this case, you’ll launch an instance into the public subnet of the VPC you created.
A security group acts as a virtual firewall to control the traffic for its associated instances. To use a security group, you add the inbound rules to control incoming traffic to the instance, and outbound rules to control the outgoing traffic from your instance.
In this step, you’ll use the Amazon VPC wizard in the Amazon VPC console to create a VPC. The wizard performs the following steps for you:
In this exercise, you’ll create a VPC and subnet, and launch a public-facing instance into your subnet.
Amazon Simple Storage Service (Amazon S3) is storage for the Internet. You can use Amazon S3 to store and retrieve any amount of data at any time, from anywhere on the web.

Amazon S3 is cloud storage for the Internet. To upload your data (photos, videos, documents etc.), you first create a bucket in one of the AWS regions. You can then upload any number of objects to the bucket. In terms of implementation, buckets and objects are resources, and Amazon S3 provides APIs for you to… Read more »
Amazon S3 is a simple key, value store designed to store as many objects as you want. You store these objects in one or more buckets. An object consists of the following: Key – The name that you assign to an object. You use the object key to retrieve the object. For more information, see… Read more »
By default, all Amazon S3 resources—buckets, objects, and related subresources (for example, lifecycleconfiguration and website configuration)—are private: only the resource owner, an AWS account that created it, can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. Amazon S3 offers access policy options broadly categorized as resource-based… Read more »

Source By: <docs.aws.amazon.com> Amazon Virtual Private Cloud (Amazon VPC) enables you to launch Amazon Web Services (AWS) resources into a virtual network that you’ve defined.
If you’ve already signed up for Amazon Web Services (AWS), you can start using Amazon EC2 immediately. You can open the Amazon EC2 console, click Launch Instance, and follow the steps in the launch wizard to launch your first instance.
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster.

Media Linux installation can be done using a variety of different media. Each installation method has different pros and cons depending on the environment you have. Here are some examples:
Linux Uses Linux is a pretty flexible operating system. Although it has got a lot of credibility over the years as a stable server platform, it is also an excellent desktop platform. Databases, mail servers as well as many appliances can be installed.
Linux is a 32 bit open source operating system. It is based on the very popular Unix operating system and it’s code is freely available (thus explaining the “open source” label as opposed to closed source where the code is not available freely).
