Peering facilitates the transfer of data in a secure manner. ## Additional Network Services * **What is DNS?** DNS stands for Domain Name System and directs internet traffic by connecting domain names with web servers. ### Amazon Route 53 Route 53 is a DNS service that routes users to applications. * Domain name registration * Performs health checks on AWS resources * Supports hybrid cloud architectures ### AWS Direct Connect Direct Connect is a dedicated physical network connection from your on-premises data center to AWS. * Dedicated physical network connection * Connects your on-premises data center to AWS * Data travels over a private network * Supports a hybrid environment #### Direct Connect in the real world 1. **Large datasets:** Transfer large datasets to AWS 2. **Business-critical data:** Transfer internal data directly to AWS bypassing your internet service provider 3. **Hybrid model:** Build hybrid environments ### AWS VPN Site-to-Site VPN creates a secure connection between your internal networks and your AWS VPCs. * Similar to Direct Connect, but data travels over the public internet * Data is automatically encrypted * Connects your on-premises data center to AWS * Supports a hybrid environment ### API Gateway API Gateway allows you to build and manage APIs. * Share data between systems * Integrate with services like Lambda --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.linuxmaster.cloud/aws/aws-certified-cloud-practitioner/networking-services.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
