Installing the system
Some important terms and concepts to understand before you install Vyatta NOS.
- Amazon Web Services (AWS)
AWS is a cloud computing service from Amazon. It provides the tools and infrastructure for businesses to run computing environments 'within the cloud'.
When you operate a computing environment within the cloud, you reduce capital expenditures to a minimum and can easily scale your computing resources up or down as required. You pay as you go, and you pay only for the resources that you use.
AWS provides several products and services to enable businesses to build the environments they require.
- Amazon Machine Image (AMI)
At the core of AWS is the Amazon Machine Image, which is a virtual machine image. You instantiate a copy of the image as a virtual machine instance within the AWS cloud.
Vendors offer a variety of AMIs — and Ciena offers the Vyatta AMI. This is a version of Vyatta that we've packaged to run in the AWS cloud. You can get it from the Amazon AWS Marketplace.
- Amazon Elastic Compute Cloud (EC2)
EC2 is the AWS infrastructure within which all AMIs are launched. EC2 allows you to easily obtain and scale computing capacity as required.
- Virtual private cloud (VPC)
A VPC allows you to provision a virtual private network within the AWS cloud. A VPC also allows you to define a virtual network topology within which you can create subnets, select IP addresses, and configure routing tables and network gateways.
In this section you'll learn how to get and launch the Vyatta AMI into a VPC within the AWS cloud and how to configure AWS such that you can access the vRouter remotely. We also provide some examples of how to configure vRouter.
