Non EC2 servers, one in Europe and one in the US. /storage are local SSDs to the machines (so it's 2 copies of the data (3 for the originals since they're also on S3)). Whether storing it back on S3 is "good enough"

I'd break it down into two parts. The first is the image transformation. For this we use graphics magic, and based on the params in the querystring, we'd crop, resize, alter the quality, anchor the image to a focus point and so on

We were handling over 10K req / sec through that layer of our system and load tested the entire system to over 100K, testing various cache hit ratios (our 95th percentile uncached response time was ~5ms for our core service). At that s

I can't speak specifically about this responsive image feature, but as for imgix's core business, I have mixed feelings. It's pretty trivial to write on-the-fly image processing using an existing graphics library. And given t

My experience with Varnish was when we tried to use it for something that had relatively complex caching rules. The config/VCL became spaghetti: attaching values to req and restarting the flow. This appeared to be the normal way to wri

RethinkDB has a long history ... someone better informed can shed some light on this, but when this was written, it was being specifically designed to be used with SSDs. Clearly, that's still not "in-memory", but it was proba

I'm pretty sure the two are related, no? A B-trees is a disk-friendly structure (shallow and wide), skiplist aren't (but they are a concurrency friendly structure)

I think you make good points. I wanted to clarify how I used in-process DBs because it clearly wasn't obvious from my post. I still rely on a "normal" database as the authoritative source of all data, and all writes go to thi

Over the last couple years, I've become a fan of in-process databases. Being able to use whatever data structures best fit your data, avoiding the network and serialisation (and subsequent GC) overhead tends to make for clean (and very

I upvoted it in the hopes that someone would provide the missing piece. Like "oh, we forgot to mention that the DNS is pointing to our own haproxy servers that all have redundant power/network/whatever) or something.

Is https termination really worth mentioning? They'll still be running some type of web server (nginx, apache, whatever) and enabling https termination there is probably easier than going through the elb wizard.

If you're using hostnames in your config file, that is a form of service discovery. One that relies on DNS. But DNS is a general solution. Are you using a public DNS server? What if it goes down? What's the minimum TTL it'l

I've been a pretty big fan of Scout (ScoutApp) for this. To me, Scout's killer feature is the ease with which you can write a custom plugin. And, if that's too much trouble, just use the Generic JSON URI plugin and have your

Banana's do not have proteins. Generally speaking proteins can be found in meat. A banana has ~1g - 1.5g of protein. By dried weight, it's a lower % of protein than a lot of other fruits. I admit it isn't much (it's ab
