Depends on what you mean by availability. AWS S3 does return 500 errors from time to time and you are supposed to retry. There are also opaque rate limiting. These are mostly hidden from you if you use the AWS sdk but still is something to

What about have the consumers sign on to the SSO provider at the root node?

by khc 8y ago
(also work for cloudflare but not on DNS) In addition, DNS queries are always encrypted, so no one can eavesdrop on them. Combined with our experimental encrypted SNI you can have a fully encrypted path from your device to us.

Typically yes. But you can have Argo without tiered caching and for Enterprise level also tiered caching without Argo

by khc 8y ago
Argo by itself does not improve hit rate, but that's often coming with tiered caching. Source: I work on the cache team at cloudflare

Is that because you have tiered caching on for your paid plans?

It's true that you usually get the lowest common denominator when you build abstractions, but cloud storage has a pretty broad set of useful common denominators. The fact that the author runs into so much trouble says more about the li

Other than the concurrent write that another comment mentioned, looks like this test is done with a data set that fits entirely in RAM. I wish we have enough RAM for the entire internet :-(

I think you are underestimating cloudflare's scale here. Obviously we do shard across many machines but each one still has many more files than what's reasonable to keep open all the time.

"isolate" here I meant prevent one process's IO from affecting another one

by khc 8y ago
our machines also run many different services (the CDN product is just one of them) and isolating I/O from different products is difficult. I'd also love to have NVMe.

right I suspect you have way fewer files than we do and everything is in the dentry cache. Pretty sure that most of your files are bigger than 60KB too :-) (which is our p90)

Author of the post (and the engineer who did the work) here. There are ways to do non-blocking disk I/O in *nix (aio/io_submit in linux) but all of which requires you to have an open file descriptor first. Does NT allow you to ope

In this case it's not possible to implement as nginx modules, but we are looking into releasing the patch as is.

Author here. I've talked to a nginx product manager and he's told me changes that are specific to one customer are unlikely to be accepted. Also in our implementation we took some shortcuts so it may not be suitable for upstream a

Yup just want to point out the replacement suggested in the blog is incorrect. Simply max-age=0 should be sufficient to emulate Expires: past date

In addition, having Expires set to a date in the past in not the same as "Cache-Control: no-cache, private". The latter instructs CDNs not to cache the file whereas the former doesn't (CDN is allowed to cache the file and rev
