Choosing Between Invalidating Files and Using Versioned File Names
To control the versions of files that are served from your distribution, you can either invalidate files or give them versioned file names. If you want to update your files frequently, we recommend that you primarily use file versioning for the following reasons:
Determining Which Files to Invalidate
If you want to invalidate multiple files such as all of the files in a directory or all files that begin with the same characters, you can include the * wildcard at the end of the invalidation path. For more information about using the * wildcard, see Invalidation paths .
Specifying the Files to Invalidate
Note the following about specifying the files that you want to invalidate.
Invalidating Files Using the Console
You can use the CloudFront console to create and run an invalidation, display a list of the invalidations that you submitted previously, and display detailed information about an individual invalidation. You can also copy an existing invalidation, edit the list of file paths, and run the edited invalidation.
Invalidating Files Using the CloudFront API
For information about invalidating objects and about displaying information about invalidations using the CloudFront API, see the following topics in the Amazon CloudFront API Reference :
Concurrent Invalidation Request Maximum
If you’re invalidating files individually, you can have invalidation requests for up to 3,000 files per distribution in progress at one time. This can be one invalidation request for up to 3,000 files, up to 3,000 requests for one file each, or any other combination that doesn’t exceed 3,000 files.
Paying for File Invalidation
The first 1,000 invalidation paths that you submit per month are free; you pay for each invalidation path over 1,000 in a month. An invalidation path can be for a single file (such as /images/logo.jpg) or for multiple files (such as /images/* ).

How does Cloudfront CDN work?
The ratio of requests that are handled by the edge server compared to the number of requests that arrive at the origin server is called the cache hit ratio. You can increase this ratio by understanding how the cache key works . When a resource is requested by a client, CloudFront generates a cache key (by default, this uses the domain of the distribution and the path of the requested object, but you can modify those settings then stores the cache key and uses it to serve future matching requests. To increase the hit percentage, consolidate application views to resolve to a single cache key and avoid adding data that might cause two requests with the same results to generate different cache keys, like creating two URLs that point at the same resource.
How to reduce requests to a web server?
One of the best ways to reduce requests to any web server is by caching content on the client’s browser . This basic idea applies twice when using CloudFront, because CloudFront adds a second layer of caching, files are also cached on edge servers. By default, all files served by CloudFront’s edge server expire after 24 hours, which is far too low for many types of content. You can increase the value of your CloudFront network by appropriately caching objects, particularly ones that you are confident will not change for a while. You can set how long both the client and edge server caches objects by setting the Cache-Control HTTP header at your origin server. You can you can also instruct your edge servers to implement their own caching policy by setting Time To Live (TTL) values when you create or update your CloudFront distribution. Be aware that edge server caching is important to plan and implement carefully because if you want to invalidate files before they expire, you can invalidate 1,000 paths for free each month but you’ll pay $0.005 per path invalidated after that limit.
What is Amazon Cloudfront CDN?
Amazon CloudFront CDN makes serving resources from a globally distributed CDN simple. This can reduce latency, handle spikes in demand, and decrease the load on your application servers.

Does Cloudfront compress files?
CloudFront can be configured to automatically compress some kinds of files. CloudFront compression will result in a faster load time for clients, and will decrease your costs as edge servers transfer smaller amounts to data to clients.

Path pattern
The path pattern is fairly obvious but I will explain with an example munki repo. Bolded items are typically where the plists will reside.
Viewer Protocol Policy
This one is simple - HTTPS Only. Don’t allow http, ever, even for testing.
Object Caching
Here is where you will want to use the Customize option. Depending on how aggressive you want to be, you will want to do the following:
Example
In the following image, you will see a full object cache rule for all munki catalogs, with a highly aggressive expiration of two minutes (120 seconds). This will mean from the time you do a s3 sync to your CloudFront instance, in two minutes, your users will be able to see new packages in Managed Software Center.
Ordering your rules
After you have created all of the rules you want, you want to make sure they are above your default rule.
