One of the biggest reasons for switching from AWS S3 to Wasabi is that you can use Cloudflare. 
Even if you don't have a need for third party storage like Amazon S3 or an S3 compatible storage, you should be investigating Cloudflare anyways with your server admin.  

Signed downloads for S3 files in IPS software is locked to Amazon S3 (bucket regions and the like all hard coded). This affects attachments (the direct downloading of them, not the viewing in posts) and Downloads files.
The S3 Compatible Downloads plugin hacks around this limitation. Read the file description fully before deciding if you want to use it but yes, all good in various hoods. I, and Joel now for that matter, can confirm as such.
Full S3 compatibility for various services (Wasabi, Digital Oceans Spaces or whatever, and so on) will require new storage handlers written to handle the various signatures required AND whatever bucket regions the services use/require.

You are welcome 🙂
I am getting a lot of positive feedback about this topic and i think (if admins agree) it will be helpfull to make it a pinned topic ....?

A perfect replacement! Thank you!

Hello
(This is a community guide on how to setup Wasabi and Cloudflare, as a significantly cheaper replacement for Amazon S3 and Cloudfront.  The author has no affiliate arrangement with any of the companies listed in the guide and offers the guide as a free community resource.  You should consult with your hosting provider and / or server administrator before proceeding with the guide.)
BACKGROUND:
Invision Communities contain rich content, from forum attachments to gallery images to download files.  These resources add up over time. 
Here are real examples of communities that I provide server administration for:
- Website A: 400 GB of total storage and 1.2 TB of total monthly bandwidth 
- Website B: 800 GB of total storage and 14 TB of total bandwidth
Invision Community allows a file storage configuration with Amazon S3 and a content distribution network (CDN) of your choice:
 
WHAT IS WASABI?
Wasabi Cloud  is faster and cheaper than Amazon S3 for object storage, offers unlimited egress for bandwidth, and compatible with Cloudflare.  One of the biggest hidden expenses of using Amazon S3 is not the cost of storage itself, but the bandwidth to deliver objects in and out.  Wasabi does not charge for egress bandwidth, which can save on the majority of the true cost of Amazon S3. It also provides an S3-compliant interface, which means it can be used as a perfect drop-in replacement for Amazon S3 storage and immediately usable on all Invision Communities.   

Wasabi is 80% cheaper and 6x faster than Amazon S3, with 100% data immutability protection, and no data egress fees or API charges. Created by Carbonite co-founders and cloud storage pioneers David Friend and Jeff Flowers, Wasabi is on a mission to commoditize the storage industry. Wasabi is a privately held company based in Boston, MA.
In March of 2018, Wasabi pioneered the cloud storage industry’s first ‘unlimited free egress’ pricing plan. We are excited to join forces with Cloudflare and the Bandwidth Alliance, validating that the early business models of Cloud 1.0 vendors no longer applies in a world that expects unlimited everything.  What this means in practice is that you can use Cloudflare services (including the free plan) like blazing-fast DNS, WAF firewall, performance improvements on the fly, and much more.  Forums users will request a topic, and all static content can be picked up from Cloudflare's optimized services that will connect to Wasabi.

 
At the moment, Wasabi offers three Datacenters:
1)US-WEST
2)US-EAST
3)EU-CENTRAL 

One price. Lightning fast speed. No hidden fees.

You can check and compare the prices above.
 
GUIDE:
BEFORE PROCEEDING, PLEASE BACKUP YOUR DATA FIRST!
YOUR FILES WILL BE IN PRIVATE MODE AND WILL NOT BE ACCESSIBLE ON YOUR FORUM !
YOU MUST GET A PAID PLAN TO BE ABLE TO ACTIVATE THE INVISION FILE PERMISSIONS AND GET YOUR FILES ACCESSIBLE AT YOUR FORUMS.
JUST ADD YOUR CREDIT CARD NOW (AT YOUR PROFILE PAGE) AND THEY WILL CHARGE YOU 5,99$ FOR A MONTH FOR 1TB STORAGE AND UNLIMITED BANDWIDTH.
THE FREE TRIAL WILL NOT WORK FOR INVISION !
 
Step 1: Create a CName at CloudFlare
We start by creating a cname at Cloudflare:
cname -> cdn -> cdn.yourdomain.com.s3.eu-central-1.wasabisys.com  <--For Europe datacenter
or
cname -> cdn -> cdn.yourdomain.com.s3.us-west-1.wasabisys.com  <--For US-WEST datacenter
or
cname -> cdn -> cdn.yourdomain.com.s3.wasabisys.com  <--For US-EAST datacenter
Like this:

 
Step 2: Create a bucket on Wasabi
First we sign up for a free account at Wasabi Cloud: https://wasabi.com/sign-up/
Then we create a bucket:

 
It is important to name it as: cdn.yourdomain.com
 

 
Then keep default suspend Versioning and Suspend Logging:

Then click CREATE BUCKET:
 

 
Step 3: Retrieve your Access Keys
Go to the menu on top left and click Access keys on the left. Click on "Create New Access Key."

 
Copy / save the access key and the secret key:

Step 4: Setting up a new file storage in ACP
Login to Admin Control Panel and navigate to Overview at the Files category and then click at the right side at Storage settings:

 
Then we click at Configurations and at the right side at Create New:
 

We select Amazon s3 and we add the following info:

Save it.
Step 5: Set the new storage at storage settings
Navigate to Storage settings and select from the drop down menu the new Amazon s3 bucket.

 
Keep only at your server your theme resources:

*Attachments and Downloads doesn't work out of the box as it seems there is some hardcoded code at Invision related to S3...
To make them work you just need to install the addon bellow: (tested with Invision 4.4.4).
 
Then wait for any Invision background tasks to finish and check.
I hope that you will benefit from this tutorial and get better performance while saving a lot of money 🙂
Enjoy!
OTHER NOTES:
If you are already using S3 then it is very easy to move straight to Wasabi by following the above tutorial as it is NOT needed to move back your files to server and then to Wasabi.

Great candidate for a pinned topic!

So, I got this to work! It's quite simple actually.  Thank you to whoever created the tutorial.  A few gotchas: make sure to set CloudFlare to Full, if you do Full(Strict) you will get the SSL error that I described above. Also, make sure to use https:// in your CDN url. Other than that it's working great so far.

It was already set to full strict. I think I messed up the custom url part, I didn't include the https in the cdn url.  I am re-running the conversion, it's basically just moving it to a new bucket in Wasabi. It appears to be moving the files correctly so hopefully this will fix it.

Keep only at your server your theme resources:

*Attachments and Downloads doesn't work out of the box as it seems there is some hardcoded code at Invision related to S3...
To make them work you just need to install the addon bellow: (tested with Invision 4.4.4).
 
Then wait for any Invision background tasks to finish and check.
I hope that you will benefit from this tutorial and get better performance while saving a lot of money 🙂
Enjoy!
OTHER NOTES:
If you are already using S3 then it is very easy to move straight to Wasabi by following the above tutorial as it is NOT needed to move back your files to server and then to Wasabi.

Thank you

Ok thank you, we will seriously look into this

You can use it on any environment that supports natively or by any plugin/addon Amazon S3. For CiC (community in cloud) yes it will work!
You can select from your admin CP which files you like to move and which not 🙂

Hello
(This is a community guide on how to setup Wasabi and Cloudflare, as a significantly cheaper replacement for Amazon S3 and Cloudfront.  The author has no affiliate arrangement with any of the companies listed in the guide and offers the guide as a free community resource.  You should consult with your hosting provider and / or server administrator before proceeding with the guide.)
BACKGROUND:
Invision Communities contain rich content, from forum attachments to gallery images to download files.  These resources add up over time. 
Here are real examples of communities that I provide server administration for:
- Website A: 400 GB of total storage and 1.2 TB of total monthly bandwidth 
- Website B: 800 GB of total storage and 14 TB of total bandwidth
Invision Community allows a file storage configuration with Amazon S3 and a content distribution network (CDN) of your choice:
 
WHAT IS WASABI?
Wasabi Cloud  is faster and cheaper than Amazon S3 for object storage, offers unlimited egress for bandwidth, and compatible with Cloudflare.  One of the biggest hidden expenses of using Amazon S3 is not the cost of storage itself, but the bandwidth to deliver objects in and out.  Wasabi does not charge for egress bandwidth, which can save on the majority of the true cost of Amazon S3. It also provides an S3-compliant interface, which means it can be used as a perfect drop-in replacement for Amazon S3 storage and immediately usable on all Invision Communities.   

Wasabi is 80% cheaper and 6x faster than Amazon S3, with 100% data immutability protection, and no data egress fees or API charges. Created by Carbonite co-founders and cloud storage pioneers David Friend and Jeff Flowers, Wasabi is on a mission to commoditize the storage industry. Wasabi is a privately held company based in Boston, MA.
In March of 2018, Wasabi pioneered the cloud storage industry’s first ‘unlimited free egress’ pricing plan. We are excited to join forces with Cloudflare and the Bandwidth Alliance, validating that the early business models of Cloud 1.0 vendors no longer applies in a world that expects unlimited everything.  What this means in practice is that you can use Cloudflare services (including the free plan) like blazing-fast DNS, WAF firewall, performance improvements on the fly, and much more.  Forums users will request a topic, and all static content can be picked up from Cloudflare's optimized services that will connect to Wasabi.

 
At the moment, Wasabi offers three Datacenters:
1)US-WEST
2)US-EAST
3)EU-CENTRAL 

One price. Lightning fast speed. No hidden fees.

You can check and compare the prices above.
 
GUIDE:
BEFORE PROCEEDING, PLEASE BACKUP YOUR DATA FIRST!
YOUR FILES WILL BE IN PRIVATE MODE AND WILL NOT BE ACCESSIBLE ON YOUR FORUM !
YOU MUST GET A PAID PLAN TO BE ABLE TO ACTIVATE THE INVISION FILE PERMISSIONS AND GET YOUR FILES ACCESSIBLE AT YOUR FORUMS.
JUST ADD YOUR CREDIT CARD NOW (AT YOUR PROFILE PAGE) AND THEY WILL CHARGE YOU 5,99$ FOR A MONTH FOR 1TB STORAGE AND UNLIMITED BANDWIDTH.
THE FREE TRIAL WILL NOT WORK FOR INVISION !
 
Step 1: Create a CName at CloudFlare
We start by creating a cname at Cloudflare:
cname -> cdn -> cdn.yourdomain.com.s3.eu-central-1.wasabisys.com  <--For Europe datacenter
or
cname -> cdn -> cdn.yourdomain.com.s3.us-west-1.wasabisys.com  <--For US-WEST datacenter
or
cname -> cdn -> cdn.yourdomain.com.s3.wasabisys.com  <--For US-EAST datacenter
Like this:

 
Step 2: Create a bucket on Wasabi
First we sign up for a free account at Wasabi Cloud: https://wasabi.com/sign-up/
Then we create a bucket:

 
It is important to name it as: cdn.yourdomain.com
 

 
Then keep default suspend Versioning and Suspend Logging:

Then click CREATE BUCKET:
 

 
Step 3: Retrieve your Access Keys
Go to the menu on top left and click Access keys on the left. Click on "Create New Access Key."

@ASTRAPI is helping me move my community over to Wasabi and Cloudflare.  
For any Invision Communities who are currently using Amazon S3, then you may want to seriously investigate the pricing for Wasabi or other S3 compliant services.  Wasabi is significantly cheaper (80% cheaper), charges nothing on exit bandwidth, and compatible with CloudFlare.  It's a drop-in replacement for S3, so for purposes of your ACP, you would treat it like an Amazon S3 storage.

top n -1 (same as above, but will output your first stat instead of constant loop) This is wrong as it should be:
top -n 1

Go to the admin panel at System->Search Engine Optimization-> and enable rewrite Urls ?

True. It is expensive !!!
$250 for a VPS?
For 250$ i can get this dedicated server:
2x Intel® Xeon® E5 2640 v4
192 GB DDR4 ECC
5x 500 GB SSD - Hardware Raid
 

Just a forewarning, S3 can be insanely expensive depending on how much media you have. I switched over to S3 and it was costing me $400 - $500 per month in bandwidth fees alone, for comparison my VPS is only $250 per month. I've heard that CloudFront can reduce the charges, but Cloudfront has it's own fees as well. Also, it was significantly slower for me. Currently, I host everything on a dedicated server and use cloudflare and it works great.
