Close, but not quite. Think of something only a little more complicated to configure than Wordpress, but far more powerful -- something that actually generates sales and provides immediate value. Software that does for other industries what

You are absolutely right, and that's the point of my post. Programming is too hard. We can't make all these people become programmers. But a lot of what we are doing as programmers shouldn't really require programming. When I'm building a w

As you say, the real trouble with EBS is when serving application data. We run a lot of databases, and EBS was just not good enough for them even when there were no system-wide issues. Our problem with EBS as a boot device was that occasion

We are planning a follow-up blog post that goes into more technical detail about our backup and restore strategies; look for it in a week or two.

We are primarily in us-east-1, as I mentioned in the post, with a skeleton set of DB slaves sitting in us-west as an emergency recovery if all of east-1 goes down. In terms of AZs, were are distributed roughly evenly across all AZs in east-

I wasn't taking you as sarcastic, nor was I attempting snark in my reply: there are real costs either way, and it's our current judgement that learning how to do a virtualized, distributed stack would be more expensive than getting AWS to d

My ops guy has reminded me that we do, like you, have one EBS drive for snapshots of one particularly hefty DB in addition to our other backup methods.

As I mention in the post, we go across AWS availability zones: these systems have physically separate power and networking. When they fail together, it's because they are connected at the software level -- usually EBS. If you're not using E

Great post! It's fascinating to see that other people have come up with the exact some solution -- we also run a "skeleton crew" server setup in us-west.

If I knew how to setup OpenVZ and create < 10ms latency VPNs across multiple datacenters, then I would be a lot better at ops than I am. While I'm much better at ops now than I was when I co-founded awe.sm, I am still primarily a develo

As others have pointed out, all EC2 instances come with large ephemeral volumes already attached as /dev/sdb, etc; you just have to mount them: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/In...

All our persistent storage is on "ephemeral" drives. If we lose the instance, we lose the data, so we have a lot of redundant slaves and backups (see my other comment).

I've not found any, which is part of why I wrote this post! It seems a lot of people blow time and money re-discovering these things.

We use Percona's XtraDB streaming backup to take backups of our smaller databases, and incremental backups of the larger DBs. We store them in a series of places: on a backup instance within east-1, on a second dedicated backup instance in

Why all Americans should be in favor of immigration reform(seldo.com)

The 55,000 STEM visas discussed in the original article are all work visas. They require a job offer and proof that no American is available to take the position. You are right that the diversity visa holders are eligible for benefits. In p

Immigrants are in no way entitled to social services. If an immigrant on a work visa loses their job, they are required to leave the country within 10 days. However, immigrants on visas still pay full taxes. So actually, immigrants make soc

Fundamentally, immigration is a market response. Demand for labor inside of a country exceeds supply -- or, more accurately, the demand for labor in the receiving country exceeds the demand in the sending country. This trade in labor is goo

If you kicked out all of the undocumented workers currently working in the US tomorrow, I can absolutely guarantee you that the American economy would immediately collapse. You need more of both.

They are Visas available to anybody, for any reason, from any country. They are good because immigration is good. But let me explain a bit further. Most American visas are related to a specific job, or a family connection, or education. You

As a recent immigrant myself -- I got my green card last week, after a 5-year application process, and I'm one of the lucky ones -- I'm a huge fan of immigration reform. However, this is not the bill to do it. The 55,000 diversity visas are

I'm sorry, but that's just not true. Prior to last week's incident: June 28th 2012 - region-wide failure due to power outage and EBS dependency issues hitting ELB and RDS: http://aws.amazon.com/message/67457/ March 15th 2012 - 22-minute,

I certainly didn't mean to imply that they should have predicted this -- my reason for scoring the number of simultaneous issues is to indicate what a shitstorm this was. That said, there are some genuine deep-rooted design flaws at work he

Enthusiastically seconded. We stopped using EBS for anything 12 months ago and got through this outage with very little pain (previous AWS incidents had us cleaning up for weeks afterwards).
