In this section of the AWS Certified Advanced Networking - Specialty learning path, we introduce you to the various networking and VPC services currently available in AWS that are relevant to the ANS-C01 exam.

Learning Objectives

  • Identify and describe the various networking services available in AWS
  • Describe how to configure an Amazon Virtual Private Cloud (VPC)
  • Understand how to control network traffic via Security Groups and Network Access Control Lists (NACLs)
  • Describe options for VPC connectivity, subnets, and routing
  • Understand how to share VPC resources using the AWS Resource Access Manager (RAM)
  • Identify how to evaluate the configuration of VPC resources using the VPC Reachability Analyzer


The AWS Certified Advanced Networking - Specialty certification has been designed for anyone with experience designing, implementing, and operating complex AWS and hybrid networking architectures. Ideally, you’ll also have some exposure to the nuances of AWS networking, particularly regarding the integration of AWS services and AWS security best practices. Many exam questions will require advanced level knowledge of many AWS services, including AWS networking services. The AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.


In this section, we will discuss the role Resource Access Manager plays in sharing of centralized resources. In order to use VPC sharing, you must work with AWS Resource Access Manager, RAM. RAM allows you to share a whole host of AWS resources from centralized AWS accounts. Using RAM, you can share resources such as Aurora DB Clusters, Dedicated Hosts, Resource Groups, and of course VPC Subnets. The first thing you should do if you want to easily use RAM is to enable sharing. This can be done through the Resource Access Manager console or through the AWS CLI. Next, using the console or CLI you create a resource share. 

When you create a resource share, you provide a name for the share and the list of resources you wish to share. Here, we can see that we are creating a share called DevTeam1 and we're sharing three subnets from the same VPC. Next, we can assign permissions to the share. The permissions allow us to restrict the actions that principles are allowed to perform on the share. If you're happy with the permissions, you can click 'Next' and identify the principles you wish to share the resources with. If you select OU, then the resources you are sharing will be shared with all AWS accounts in the organizational units and any new AWS accounts that are added to the OU in the future. We would then complete the wizard and very quickly the shared resources, in this case three shared subnets, would appear in the VPC console of the chosen AWS accounts.
