Well, there's spot instance pricing and reserved instances with AWS that nobody can touch. What "native load balancing" are you referring to that has no equivalent with AWS? There are many options for EBS - including magnetic storage. I doubt you can beat the speed of EBS with provisioned IO! Maybe you weren't using the right type for your need!

From AWS article on Best Practices in Evaluating Elastic Load Balancing, section Pre-Warming the Load Balancer: "In certain scenarios, such as when flash traffic is expected, or in the case where a load test cannot be configured to gradually increase traffic, we recommend that you contact us to have your load balancer "pre-warmed". We will then configure the load balancer to have the appropriate level of capacity bas…

Although we've used to call support and request a higher capacity ELBs (you can't get this automatically), recently we stopped doing it recently and handle spikes from 1,000 to 100,000 concurrent users within a couple of minutes without a sweat. By the way, many people are unaware, but CloudFront distributions also need to be upgrade to handle spikes similarly to ELBs.

Edit: retracted, after a closer look at your previous comments.

I did PhD in Cloud and Big Data (Created a Cloud and Big Data platform for crunching large scale images on satellite clusters). I spent about 10 years of my life working on nothing but Cloud and Big Data. And I rarely do comment on anything outside my area of expertise. If you find any of my comments incorrect or interesting, I will be more than happy to engage in a conversation with you. This is also third or fourth…

At least mgnacl's nick is explicit in telling you to take his/her comment with a grain of salt.

Google CDN looks very similar to what Cloudflare Free Plan offers. A no-Frills, fully automated setup with little or no control on how your content is being delivered. Main difference with Cloudflare being that Google forces you to use GCP as Origin and you have to pay for the CDN service (Bandwidth, purge, requests...) which Cloudflare offers for free and you can use any Origin server. Not sure why someone would use…

I don't know if Google does this, but because they control both endpoints (cache server and load balancer) of the longest section of the path they could accelerate it by replace HTTP(S) there with something like CloudFlare's Railgun. [1]

Since Railgun is only available at CloudFlare plans starting at $200/month, this could make the Google offering attractive for certain customers.

In any case, it is hard to beat free for most sites with moderate needs.

> Cloud CDN is Google’s own CDN solution for sites running in VMs inside Compute Engine. It is designed and implemented a bit differently from other CDNs, since it is meant to cache not only static content, but practically a whole site in more than 50 edge caches globally. I'm not seeing what's so special here. Other CDNs can do whole-site acceleration and caching (Akamai Sureroute, EdgeCast ADN). > It is a whole new…

That's definitely a misunderstanding on the author's part. I think our own landing page ( https://cloud.google.com/cdn/ ) actually makes this clear: there are caches at the edge, but we (currently) deeply understand your origin (our compute engine VMs) and don't require any funny modification to your setup (just click a button) or look any different than your existing anycast IP for L7 Load Balancing. Disclaimer: I w…

OP Here> The setup was as follows: VM instance in each of the 4 cloud regions around the world:

Council Bluffs, IA (us-central1) Berkeley County, SC (us-east1) St. Ghislain, Belgium (europe-west1) Changhua County, Taiwan (asia-east1)

So on any cache miss at one of the 50+ edge POPs, the cloud HTTP(S) load balancer will direct the request to the nearest cloud region. The resulting cache fill happens over Google's global network, which is fast. Once that cache fill happens, that edge cache can serve the content directly to clients, which is even faster.

Would be cool if you could add an image of the table with average measured times by country for the selection of european countries. (Marked with double asterisk in the post)

I guess the difference between these countries could be noticeable.

Alternatively you could post it here. I'm mainly interested in the Swedish numbers.

Anyone want to start a pool on how long until Google shuts it down when it doesn't end up as #1 in the market?

You can't have a convincing cloud story without CDN. I'm an Azure guy but Google's investment here is clear. I'll take that bet.

So just radical changes to pricing then? And cutting of features of course.

Something that is unclear to me here, can I origin pull from anywhere? or is this purely for compute engine now? Regarding free SSL are we talking SNI here or is this free non SNI HTTPS hosting?

Right now it's just compute engine (Source: cloud.google.com/cdn). I'm not sure on the SNI part, but like you I assume that's the case. Edit: Nope! A little birdie pointed out to me that since "each HTTP(S) LB gets its own Anycast VIP, so there's no need for SNI."

That's right, since it is based on the global load balancing tech, you get a single IP for all edge locations which means you can use your own custom SSL (without the need for SNI) at no extra cost (which would cost you $500/month on AWS CloudFront).

I just naturally assumed Akamai would use anycast for their CDN, but it is actually DNS based[1].

No mention of if their DNS is anycasted, one would presume so.
