AWS Networking & Content delivery Flashcards
What is 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
NB:
Did you know that if the content is already in the edge location, CloudFront delivers it immediately? If not, CloudFront retrieves the files from the origin.
How to use Amazon CloudFront in the Real world?
- CloudFront is used with S3 to deploy content (Static Website)
- CloudFronT can stop certain web attacks like DDoS.
- Geo-restricition prevents users in certain countries from accessing content.
What is 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
What is 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
What is Amazon Virtual Private Cloud (VPC)
Amazon 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
- A VPC spans Availability Zones in a Region
NB: Internet gateway allows access to the public internet
What is VPC Peering?
VPC peering allows you to connect 2 VPCs together. Peering facilitates the transfer of data in a secure manner.
What is 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
What is AWS Direct Connect?
Direct Connect is a dedicated physical network connection from your on-premises data center to AWS.
- Dedicated physical network connection
- Connects you on-premises data center to AWS
- Data travels over a private network
- Supports a hybrid environment
What is 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
What is virtual private gateway in AWS?
You can use an AWS Direct Connect gateway to connect your AWS Direct Connect connection over a private virtual interface to one or more VPCs in any account that are located in the same or different Regions. You associate a Direct Connect gateway with the virtual private gateway for the VPC. Then, you create a private virtual interface for your AWS Direct Connect connection to the Direct Connect gateway. You can attach multiple private virtual interfaces to your Direct Connect gateway
What is a Customer Gateway Device?
A customer gateway device is a physical or software appliance that you own or manage in your on-premises network (on your side of a Site-to-Site VPN connection). You or your network administrator must configure the device to work with the Site-to-Site VPN connection.
