For contrast: why containers are a poor choice for small, function-based workloads on the edge: https://blog.cloudflare.com/cloud-computing-without-containe...

It seems like their initial edge Engine uses the same approach as CF: plain V8 runtime.

This announcement to me sounds like the approach didn't get the expected adoption and now they're allowing regular containers in the edge.

We prefer both :)

We've seen amazing adoption on the EdgeEngine product, it just serves a different purpose than full on Containers and/or VM's at the Edge.

The ability to run a container/VM at the Edge enables the ability to run more complex workloads outside of scripting in a CDN like delivery pipeline.

Ben from the StackPath product team here. We agree containers or VM's may not always be the best available option for a workload. That's why we also offer an equivalent product to the one by Cloudflare (great product btw) - https://www.stackpath.com/services/edgeengine/

However, it should be made clear that our container and VM solution is not a "function" type offering. You can deploy a container and/or VM workload on our Edge similar to what you might find at Cloud providers. The main difference is we sit a layer above the cloud providers and make deploying worldwide simple, secure, and fast.

With a few clicks or a single API call you can deploy a micro-service all over the world (even add an anycast IP if you need one) in under 60 seconds.

What cloud provider is under the hood?

Seems pretty pricey, smallest container is about $70/month for each region and each instance

Just saw the EdgeEngine post recently too, looks like some good competition to Cloudflare along with Fly.io.

The pricing is higher though and some early testing showed inconsistent performance, might have to wait until it matures a bit. Also missing IPv6.

Is there an open source alternative to this shared runtime? I can't quite recall seeing this process-level isolation in the FaaS sphere, maybe except for gVisor. Thanks.

Given my experiences with Stackpath's CDN, I wouldn't trust them with any sort of workload. They bill themselves as the "secure" CDN, yet were not validating SSL certs on the origin.

spben6• 7 years ago

Sorry to hear about this experience, would love to know more as we take security very serious.

Our CDN certainly will validate SSL certificates at the origin if the setting is enabled.

With that said, you may be on a legacy CDN product often referred to as "Secure CDN" and that setting may differ from our current CDN offering.

I'd be more than happy to loop our CDN team in to clarify. Feel free to reach out directly to product at stackpath.com and I'll get it setup :)

Not really the "edge". Just a data center nearer the user, like Akamai.

Is it worth the hassle? All you're saving is latency in the backbone between the point of presence and your home data center. Does this beat directing requests to the nearest AWS region? As long as you're in roughly the right hemisphere and time zone, you're probably close enough.

manigandham2• 7 years ago

Of course every "edge" is just another data center, but there's a massive rise in functions/serverless computing platforms focused on moving compute to more PoPs globally. Some have now graduated to running full containers as well.

If you have a stateless app, or state that can be deployed in multiple locations, then these are good solutions compared to doing it yourself and are relatively easier to deal with than the IaaS options of the clouds. Having it built into the CDN layer only helps with performance.

It probably doesn't matter if you're in the US or Western Europe, but could matter a lot in other regions. I don't know about Stackpath's PoP but Cloudflare and Akamai have PoP with much lower latency in many regions than the next data center by a cloud provider.

Edge can be defined as many things, and is currently being defined by the world in many ways.

At StackPath our definition of Edge is basically being as close as possible to the eyeballs aka users. Think of it as the front door to the internet.

Today our Edge expands across major IX's around the world and that's just the beginning. 5G is approaching us quickly along with container data centers.

The way we built our orchestration system it can deploy and manage workloads anywhere. In the future, that will include 5G container data centers which gets workloads even closer to things like self-driving cars, smart cities, IoT devices, <insert your idea here>.

"workloads even closer to things like self-driving cars, smart cities, IoT devices"

Oh, please. If you really need those last few milliseconds of lag reduced, you need local computation. If you don't, an AWS datacenter on the same continent is probably good enough.
