Networking Services Flashcards
What are AWS Networking Services?
VPC and Subcomponents
Don’t forget about an internet gateway allows traffic to the public internet and peering connects 2 VPCs together
What is a Virtual Private Cloud (VPC)?
Is a foundational service that allows you to create a secure private network in the AWS cloud where you launch your resources.
* Private virtual network
* Launch resources like EC2 instances inside the VPC
* Isolate and protect resources
* Spans AZs in a Region
* Network Access Control List (NACL) ensures the proper traffic is allowed into the subnet
* Router defines where network traffic is routed
* Internet gateway allows public traffic to the internet from a VPC
What is Route 53?
A highly available and scalable DNS service that routes users to applications. It performs health checks on AWS resources and supports a hybrid model
What is Direct Connect?
A dedicated physical network connection (super fast).
It connects your on-prem data center to AWS.
Remember that Direct Connect supports a hybrid model
Real world examples
* Transfer large datasets to AWS
* Transfer internal data directly to AWS bypassing your internet service provider.
* Build hybrid environments
What is Site-to-sit VPN?
Creates a secure connection between your internal networks and your AWS VPCs.
Similar to Direct Connect but data travels over the public internet.
Remember that a Site-to-site VPN supports a hybrid model.
Review components such as virtual private gateway and customer gateway.
What is API Gateway?
Allows you to build and manage API (Application Programming Interface is a way for two or more computer programs to communicate with each other)
A fully managed service that makes it easy for developers to publish, maintain, monitor and secure application programming interfaces at any scale. It acts as a “front door” for applications to access data, business logic, or functionality from your back-end-services.
