Network Services

1. Network Services

Let's see how AWS facilitates networking for cloud resources hosted across distant locations.

2. Unlock the power of AWS networking services

This video will explore networking resources that enable secure communication and content delivery between users and the cloud through five AWS services - Amazon VPC, Amazon VPN, AWS Direct Connect, Amazon Route 53, and Amazon CloudFront.

3. Networking in the cloud

Amazon VPC establishes networking in AWS by providing a private, logically isolated space in the global AWS infrastructure for defining and launching resources. VPCs are regionally hosted, residing in one AWS region.

4. Building a logically isolated virtual network

Amazon VPC provides a dedicated network supporting IPv4, IPv6 and customizable IP ranges.

5. Building a logically isolated virtual network

It provides security layers with groups and ACLs

6. Building a logically isolated virtual network

offering control over subnets, route tables, and gateways. Let's explore these features!

7. Understanding key VPC concepts

IP addresses are your virtual address spaces on the network, and VPCs let you define it. Subnets, or sub-networks, are smaller VPC portions. Think of it like dividing a large office into manageable departments.

8. Understanding key VPC concepts

Route tables hold rules to guide traffic from your subnet or gateway. Network gateways facilitate connections between your VPC and the internet, or other VPCs, managing both inbound and outbound traffic.

9. Default vs. custom Amazon VPC

VPCs come in two forms. Default VPCs are auto-created with pre-configured settings for every AWS account. They host a subnet in each availability zone of the region where the AWS account exists, and can communicate with the internet by default.

10. Default vs. custom Amazon VPC

Custom VPCs are user-defined with customizable features like IP addresses and route tables, and require explicit settings to allow internet access.

11. Network security

Security is key for robust networking. AWS offers two services controlling inbound and outbound traffic to VPCs for secure connections. Network access control lists operate as a virtual firewall at the subnet level, while Network Security Groups perform the same operations directly for AWS services.

12. VPC endpoints

Beyond security, resource communication is important for networking. VPC endpoints enable private, secure connections between AWS services without public IP addresses.

13. What is AWS PrivateLink?

AWS PrivateLink is a VPC endpoint enabling private connectivity between VPCs, other supported AWS services, and on-premises networks. It enhances secure data exchange and reduces network and firewall complexities.

14. Connections - AWS VPN

Two other ways of connecting to AWS that we have previously seen, are AWS VPN and AWS Direct Connect. To recap, AWS VPN securely connects on-premises networks to AWS over the internet, suitable for smaller workloads.

15. Connections - AWS Direct Connect

AWS Direct Connect offers dedicated, highly secure, and internet-free network connections for consistent, high-bandwidth workloads.

16. DNS - Internet's address book

Services connect in specific ways, and how about humans? DNS, or Domain Name System, acts as the internet's address book, translating user-friendly domain names to IP addresses for website access.

17. Amazon Route 53

Amazon Route 53 is AWS's DNS service that facilitates efficient communication within AWS and external services, offering high scalability and availability. It's widely used for hosting web applications and distributing incoming traffic across resources.

18. Information movement in the cloud

Moving information in the cloud is challenging due to geographical latency and bandwidth constraints affecting transfer speeds when moving data across continents.

19. Content Delivery Networks (CDNs)

AWS solves this problem by providing dedicated content delivery mechanisms. CDNs, or Content Delivery Networks, position servers globally to enable fast delivery through caching

20. Content Delivery Networks (CDNs)

provide content distribution over the internet

21. Content Delivery Networks (CDNs)

And efficiently scale for traffic changes.

22. Amazon CloudFront

Amazon CloudFront is AWS's global CDN, that excels in fast content delivery across AWS services

23. Amazon CloudFront

accelerates web content, APIs, and streaming.

24. Amazon CloudFront

And enhances content security with DDoS protection and HTTPS support.

25. How is CloudFront used?

CloudFront accelerates website content for improved user experience,

26. How is CloudFront used?

optimizes streaming for reduced buffering times,

27. How is CloudFront used?

and scales automatically to deliver patches and over-the-air updates to devices.

28. Let's practice!

Time for a rapid AWS networking knowledge check!
