Include an opening and closing sentence for the article.
If you're looking to improve the performance of your website or web application, one of the first places to look is your content delivery network (CDN). A CDN can help to improve the loading speed of your content by caching it at locations around the world, so that users can access it more quickly.
One of the most popular CDNs is Amazon CloudFront, which is a service that sits on top of Amazon's AWS infrastructure. CloudFront is a global CDN that delivers your content through a network of edge locations. It's easy to set up and configure, and it integrates with other AWS services.
In this article, we'll take a look at how to improve content delivery with CloudFront. We'll cover the following topics:
To get started with CloudFront, you'll need to create a distribution. A distribution is a collection of AWS resources that are used to deliver your content. To create a distribution, you'll need to specify the following:
Once you've created a distribution, you'll need to wait for it to be deployed. This can take up to 15 minutes. Once the distribution is deployed, you'll be able to access your content through the CloudFront URL.
Once you've set up your CloudFront distribution, you'll need to configure it to work with your website or web application. The first thing you'll need to do is create a cache behavior. A cache behavior determines how CloudFront handles requests for your content.
There are two types of cache behaviors: default and custom. Default cache behaviors are applied to all of the files in your distribution, unless you specify a custom cache behavior for a specific file or folder. Custom cache behaviors are applied to specific files or folders, and take precedence over the default cache behavior.
To create a cache behavior, you'll need to specify the following:
Once you've created a cache behavior, you can specify additional settings, such as the following:
CloudFront can be used with other AWS services to improve the performance of your website or web application. For example, you can use CloudFront with Amazon S3 to deliver content from an S3 bucket.
To do this, you'll need to create a bucket and then configure CloudFront to use the bucket as an origin. You can do this by creating a cache behavior for the bucket.
Once you've done this, you can use CloudFront to deliver the content from the bucket to users. CloudFront will cache the content at edge locations around the world, so that users can access it more quickly.
You can also use CloudFront with Amazon EC2 to deliver content from an EC2 instance. To do this, you'll need to create an instance and then configure CloudFront to use the instance as an origin. You can do this by creating a cache behavior for the instance.
Once you've done this, you can use CloudFront to deliver the content from the instance to users. CloudFront will cache the content at edge locations around the world, so that users can access it more quickly.
