How does Efficient Cloud Egress reduce data transfer costs?

Noraina's data centres are directly connected to the AWS, Microsoft Azure and Google Cloud networks, which gives access to the transfer pricing those providers offer their largest customers. Your traffic leaves the cloud through Noraina's instances instead of the provider's internet egress, and we pass the lower price on.

Do I have to move my application to use Efficient Cloud Egress?

No. Your application stays where it is. Efficient Cloud Egress sits in front of it as a caching and delivery layer, and you can fail back to serving directly from the cloud at any time.

Should I use Efficient Cloud Egress or Cloudflare?

They solve different parts of the problem. Cloudflare R2 and CDN are the best fit for static content and for security. Efficient Cloud Egress is built for dynamic and long-tail content that a CDN rarely has in cache. Many customers use both, with Cloudflare for security and static assets and Efficient Cloud Egress for the dynamic traffic that would otherwise be billed by the cloud provider.

How much does Efficient Cloud Egress cost?

It is priced in credits. One credit covers 1 GB of transfer, and an instance uses 0.5 credits per hour, about 365 credits a month. Credits cost from $0.050 down to $0.031 each depending on the volume you buy.

Efficient Cloud Egress

How it works

Your application keeps running in AWS, Azure or Google Cloud. Efficient Cloud Egress instances in our data centres sit between it and your users: they fetch from your origin over the direct connection to the provider, cache what can be cached, and deliver to the internet from our network. You pay the provider’s much lower private-transfer rate for the origin traffic, and we charge for delivery in credits.

Built for dynamic and long-tail content

CDNs are excellent at static files that many users request. They help much less with API responses, personalised pages or large catalogues where each object is requested rarely, which is exactly the traffic that drives most cloud transfer bills. Efficient Cloud Egress is designed for it:

Persistent connections to your origin and caching where the content allows it.
Request collapsing: cacheable objects are locked so only one request per object reaches your backend.
Serving stale content while it updates in the background, so users never wait for a slow origin.
Dynamic pages passed straight through when they cannot be cached.

Two layers with Cloudflare

Many customers with dynamic applications use both: Cloudflare in front for security and for static assets such as JavaScript, CSS and images, and Efficient Cloud Egress behind it for the dynamic traffic that would otherwise be billed by the cloud provider. As a Cloudflare partner we design and run both layers together.

Included

HTTP/2 and your own TLS certificates.
Static and dynamic content.
Active/active instances in more than one region for resilience.
Easy failback to serving directly from the cloud.
Logs available to download.
Management from the web console, Ansible, Terraform or the API.
24x7 support.

Pricing

Efficient Cloud Egress is priced in credits, with no commitment to a provider plan. All prices exclude VAT.

Usage	Credits
Data transfer	1 credit per GB
Efficient Cloud Egress instance	0.5 credits per hour (about 365 per month)

Credits bought	Price per credit (USD)
512	$0.050
1,024 or more	$0.045
10,240 or more	$0.040
51,200 or more	$0.037
102,400 or more	$0.035
512,000 or more	$0.033
1,048,576 or more	$0.031

For example, 5 TB a month with one instance uses 5,120 + 365 = 5,485 credits; at $0.045 per credit that is about $247 a month. How much you save depends on your provider, region and volume, so send us a recent bill and we calculate it on your real traffic.
