I think it's definitely competitive if you look across all the entrants in this space (or similar/adjacent) ones. That doesn't necessarily make us the lowest priced however ;-). Roughly speaking a million measurements costs $2.00 with our c

Appreciate the feedback (librato co-founder here), we should definitely make that clearer on the pricing page and elsewhere. We're in the process of adding some content around that now. In short a measurement is a single datapoint i.e. &#60

Thanks! One more thing, right after hitting reply, I realized the numbers you saw sounded too high. So I checked out our pricing page and it turns out we had a regression in the estimator. 50 metrics reported every 60 seconds costs $4.46, n

Sure thing! Our backend is horizontally scalable and triply redundant by design. We have a web tier behind an ELB that runs our API ( http://dev.librato.com/v1/post/metrics ). It's implemented in Sinatra today. We'll probably switch to some

Another alternative is to consider a service that handles storage/visualization/alerting/etc for your time-series data. I work for a startup that does exactly that and there are other options in this space as well. Would love any feedback

Perhaps I'm assuming too much, but it looks like you might be confusing notification with queueing . As you found with SQS, queueing systems can make for poor notification mechanisms. Did you try using AWS SNS ( http://aws.amazon.com/sns

I'm finding a lot of these articles about "surviving" the outage fairly frustrating. They generally boil down to a combination of the following: 1. "We use a multi-AZ strategy!" - This outage affected multiple AZ's concurrently. If you did

I should clarify, if your title was "How we minimized the impact of the cloud-pocalypse", then the content of the article is fine. I think most SaaS operators would define "surviving" as no downtime e.g. Netflix.

This "cloud-pocalypse" simultaneously affected multiple availability zones in US-East. Had you had the misfortune to have your multi-AZ pair in two affected zones you would have had significant downtime. The only architectures that were tru

GoF wrote about the Strategy Pattern (and the rest of them) in 1994, so I'm pretty sure Java (first public release in 1995) was the least of their concerns at the time. And believe it or not, there are times when languages with closures are

The "Conditional Inherited Modules" seems to be one (of many) possible implementations of the venerable Strategy pattern from GoF ( http://en.wikipedia.org/wiki/Strategy_pattern ). It's a really elegant and one of my favorites. Just define

Your compiler may offer a more formal way to indicate that it's acceptable for a parameter to be unused. In gcc it's an attribute: int foobar(int foo, int bar __attribute__((unused))) { /* Code that does not use bar */}

I highly recommend using fresh pasta if you have access to it. In the US most grocery stores carry it in one of their refrigerated aisles. It's more expensive but the texture is night and day. Be sure to read the instructions as you need on
