Amazon CloudFront

 Amazon CloudFront



Amazon cloudfront is CDN (Content Delivery Network) service that allows to serve your content with little or no delay effortlessly. The content copied to the edge locations all over the world. Edge location is a site that AWS uses to cache contents to improve latency. So when user access the content he/she will receive it from the closest AZ (Availability Zone).

This is how it works :

We provide CloudFront origin, it can be S3 bucket files (for example: html, pdf etc.) or another origin such as web app. you run on EC2 instance or a Load Balancer. So after that CloudFront starts caching them in Regional Edge Cache and those propagated to Edge Locations as well. So by that your content becomes globally available. CloudFront reduces latency and improves performance.

You can also utilize AWS Shield (DDOS protection) and WAF (web threat protection) technologies to protect your resources.

Let's create simple web page and serve it over S3 bucket. And use CloudFront as CDN so our webpage will load faster.


  1. Create one S3 bucket with public access. Check the steps here :

  2. After that let's configure CloudFront specifically for this purpose.






  3. Select the bucket public address from list. And make sure you clicked "Use website endpoint" button. 



  4. Make sure caching preferences look like the one below.





  5. Make sure "Last modified" part has date/time, if it is in "Pending" state thin means you have to wait more to content propagate fully.



  6. When you navigate to the address, will be able to see your page content.

AWS - Databases DynamoDB, RDS

AWS - Databases There are 3 main database types in software world: Relational databases (MySql, Postgre, Amazon RDS etc.) Non-relational databases (Mongo, Amazon DynamoDB etc.) Graph databases (Amazon Neptune, NebulaGraph etc.) For your specific use case they have advantages and disadvantages.  We will cover relational and non-relational databases in this post.  Relational databases - as name implies stores information based on defined relation. Organized by tables, columns, rows. Supports complex queries and joins. Non-relational databases - contrary to the relational databases non-relational databases are more flexible. Documents, key/value, columns and graphs are some forms can be used to organize data. Databases in Amazon There are few ways to use database in AWS : Database on EC2 - We deploy any database software onto our instance and use it like this. Amazon RDS  - Amazon provided service, under the hood you can use (MySql,Postgre,Maria Amazon Aurora etc.) relationa...

S3

 S3 In AWS S3 storage is special kind of storage that provides flexibility that other kind of storage services don't provide. S3 is sitting internet facing subnet and if we want to access S3 bucket from our private subnet we need to either direct traffic over internet gateway or use S3 gateway endpoint service.  To access or upload files to S3 we must use REST API for that. This actually makes things easier because thanks to this we will be able to do all operations programmatically (via our favorite programming language). In block storage service we supposed to use operating system to perform all the tasks. There should be some kind of hierarchy. But in S3 files storage in "bucket"s. Hierarchy can be mimicked by prefixes.  Let's create bucket and access over internet Search S3 in the search bar  Create a bucket Name must be unique otherwise it will display an error. Use default settings. After that try to upload some files there. Click to that file you will see the ...
