- And in today's session, we will learn about Cloud front. It's going to be totally visualized. So please watch it till the end.
⭐Amazon CloudFront is a Fast, highly secure, and programmable content delivery network (CDN).
⭐And as AWS tells us that, Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and
as well as APIs to the customers globally with low latency, and helps with high transfer speeds.
⭐And CloudFront is integrated with AWS -so what means is that CloudFront is integrated with both physical locations that are directly connected to the AWS global infrastructure and as well as other services we have for AWS.
Timelines for your convenience:
00:20 - What is Content Delivery Network? How does it work?
01:18 - Single Server Distribution architecture
06:00 - Amazon Cloudfront and How does it work?
09:56 - Edge Location and Regional Edge Caching.
14:36 - What is Origin?
17:10 - How does CloudFront serve request?
19:59 - Restriction access to Amazon S3 content by using an Origin access identity.
22:52 - Using EC2 instance as the origin for CloudFront.
23:36 - Using ALB as the origin for CloudFront.
24:48 - How can I restrict users in certain locations from accessing web content served by my CloudFront distribution?

This is by far the VERY BEST EXPLANATION on youtube, on CDNs, Edge Locations, and CloudFront. There really isn't any video on youtube as good as this for explaining CloudFront in detail. It even mentioned Lambda@Edge; absolutely fantastic.
I've been searching youtube for such a long time, but the content was weak or inaccurate. I thoroughly enjoyed your introductory content on a CDN.
Your content is excellent.
Many thanks for this.
Wow, thanks!
Amazing content as always, well explained, with great graphics to make it easier to understand, thank you!
good pacing & good production quality, kudos!
Thank you. Very useful
Thanks for the detailed explanation, one of the best content on this topic for sure!!
Thanks for the support
Explanation was simple and absolutely wonderful.
Please do include case studies as well
Sure would take this point 🙂 thanks for the feedback
nice tutorial. can you explain how will it work for dynamic content and hosting APIs? what is the benefit?
Really great content here. Are you sure about not being able to use Static web-site S3 hosting bucket as an origin for CDN? (15:41) I'm fairly certain we did just that in a lab for the certification training. I could be wrong. Edit: ok, I see you went on to explain that is a custom origin config. Very nice...
you are amazinggg dude!
thank u 🙏
Can we cache a some paths like /profile/*, /setting/* etc which is in one of the target groups of ALB.
CLOUDFRONT will be in Front of ALB.
and Alb has different FrontEnd application's as a target groups for different paths. ( This should be default * ) no caching for other applications
Really nice explanation ✌🏻
Glad you liked it
Pythoholic yes i really liked it and waiting for the practical part and will also share after that
The content shown in the video is very useful for preparing AWS certification. @pythoholic please also share its pdf version so that it can be quickly revised if required.
Thanks for the support. Yeah sure it can be done
Mate, this was a great and clear explanation! Do you have any videos about Cloudfront Caching?
Yes but it's more on the cookie part. Please check the Playlist
Hi,
I have cleared SAA c03. Your videos are amazing and very comprehensive. This the only channel which cleared all my concept thoroughly.
Do you have videos for AWS SAP -02. I am pursuing for the professional certification.
Hello srinivas Many congratulations
That's awesome , currently I don't have videos on that. But many congratulations once again
Isn't TH-cam distributed/Hosted on Google's Cloud offering?
Good, video. Thank you for introducing the OAI; was wondering about that.
Yes it is
What about WAF at edge location
If we are using ALB as a origin for distribution, EC2 Instances need not to be Public. mentioned at 23:53
Brother thank you for clearing the doubts I want to know is there any pop quiz like resources where i can test my knowledge before going for exam
Thanks for that, sorry currently i dont have that now, but u can try google or digital training cloud or whizlabs for the test paper. Please cover test papers before going to exam.
If the user is closer to Origin, still accessing through edge location is recommended?
Not essentially. If u are using cloud front in realtime u must understand u are paying for the resources that you are using. Every request that is made costs you. So if your users are not far away from you and they are not facing lag or performance issues then its ok to not use it.
@@Pythoholic will system decide how end user has to be serviced? Direct origin or though edge location. Am I right?
I think mostly the design team will decide if this application has to be served only in our region or it has to be wide spread.
If the application grows they have to be scaled to meet the demand. The system decides when we have apolicy attached to it. May not be in this case. Unless u have a automation in place. Mostly it works with asg.
With cloud front u decide what is the static content that is most widely used and which has become a bottleneck , for that we try and distribute it with cloudfront
at 18:09 the explanation is wrong. When a user types in a URL, it goes to the Domain Name Server for resolution. In this case, if the DNS is configured in AWS, it is Route 53. Route 53 should be configured to redirect the request to the edge location (using either latency or geo-proximity)
Yes technically you are correct, but the explanation is not wrong but may be insufficient. Please don't be so harsh :D just kidding, yes it does the route to DNS to resolve it but only if you have one. This was an overview of the explanation for simple understanding.
Thanks for the feedback. It helps me keep myself in check.
I am trying to follow this series, but the episodes are not in seq manner, so I'm finding it difficult
Oh ok. I have kept them in sequence, i will try to talk to youtube for this playlist settings.
well explained but demo would have give better understanding..
There is a demo as well
@@Pythoholic Could you please share the Demo url. I dont find it here. Thanks again.
Do You have Cloudfront failover hands on lab
No sir not yet. Will make one soon
@@Pythoholic you are one of the best channel to learn AWS. Can you tell some simple projects for beginner and intermediate
Here are some simple AWS project ideas
1. **Deploy a Static Website on S3:**
- **Objective:** Learn how to use Amazon S3 to host static web resources like HTML, CSS, and JavaScript files.
- **Key Services:** Amazon S3, AWS IAM, Route 53 (optional for custom domain).
- **Steps:**
1. Create an S3 bucket and enable static website hosting.
2. Upload the static web files to the S3 bucket.
3. Update the bucket policy to make the content publicly accessible.
4. (Optional) Configure a custom domain using Route 53.
2. **Simple Web Application with DynamoDB:**
- **Objective:** Develop a simple web application that uses DynamoDB to store data.
- **Key Services:** AWS Lambda, Amazon API Gateway, Amazon DynamoDB, AWS IAM.
- **Steps:**
1. Create a DynamoDB table to store data (e.g., a simple CRUD for tasks or notes).
2. Implement Lambda functions to handle CRUD operations on the DynamoDB table.
3. Use API Gateway to create RESTful endpoints for the Lambda functions.
4. Secure the application using appropriate IAM roles.
3. **Deploy a Python Flask App to Elastic Beanstalk:**
- **Objective:** Learn how to deploy a simple Python Flask application using AWS Elastic Beanstalk.
