Content Delivery Services

A CDN is a mechanism to deliver content quickly and efficiently based on geographic location.

Amazon CloudFront

  • CloudFront is a CDN that delivers data and applications globally with low latency.
    • Makes content available globally or restricts it based on location
    • Speeds up delivery of static and dynamic web content
    • Uses edge locations to cache content
  • Use Cases:
    • S3 Static website: CloudFront is often used with S3 to deploy content globally.
    • Prevent attacks: CloudFront can stop certain web attacks, like DDoS. We'll talk more about DDoS in the security lesson.
    • IP Adressing Blocking: Geo-restriction prevents users in certain countries from accessing content.

Amazon Global Accelerator

  • Global Accelerator sends your users through the AWS global network when accessing your content, speeding up delivery.
    • Improves latency and availability of single-Region applications
    • Sends traffic through the AWS global network infrastructure
    • 60% performance boost
    • Automatically re-routes traffic to healthy available regional endpoints

Amazon S3 Transfer Acceleration

  • S3 Transfer Acceleration improves content uploads and downloads to and from S3 buckets.
    • Fast transfer of files over long distances
    • Uses CloudFront’s globally distributed edge locations
    • Customers around the world can upload to a central bucket

Amazon Additional Networking Services

  • DNS(Domain Name System): 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.
    • highly available and scalable
    • Domain name registration, Performs health checks on AWS resources, and Supports hybrid cloud architectures
  • Amazon Direct Connect
    • Direct Connect is a dedicated physical network connection from your on-premises data center to AWS. (That means it's super fast.)
    • Connects your on-premises data center to AWS, Data travels over a private network, and support a hybird environment.
    • Use Cases: large datasets: Transfer large datasets to AWS; business-critical data:Transfer internal data directly to AWS, bypassing your internet service provider; hybird model: Build hybrid environments

  • Amazon VPN (Slightly cheaper than Direct Connect)

    • 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, and support a hybird environment
    • Use case: A Site-to-Site VPN makes moving applications to the cloud easier.
    • VPN Tunnel(where the Virtual Private Gateway is the VPN connector on the AWS side and the Customer Gateway is the VPN connector on the customer side.)

  • Amazon API Gateway

    • API Gateway allows you to build and manage APIs.
    • Share data between Services, and Integrate with services like Lambda
    • Use case example:
