This violates the promise of read committed. In RC, all transactions are supposed to see the most recently committed version of a record. The fact that it was a delete, then an insert is an implementation detail and "not my problem&q

The DBA in me is having a difficult time understanding PostgreSQL's behavior with regard to the delete/insert within a transaction? In MySQL, I get the exact behavior that I expect with anything above RC isolation level (which is

It does, but it's not very useful, as you cannot have a VIP span multiple AZs and typically a spontaneous instance failure is correlated with an AZ problem. ENIs (and IPs) are tied to a subnet, which is tied to an AZ. Even the exampl

That's a great accomplishment in such a short period of time. I'm glad that you were able to save time and money by using another service. Thankfully, there are tons of options out there to suit every business' use cases.

A bunch of Chef cookbooks does not AWS make. Configuration management tools are of course a necessity in AWS but do not replace their offerings. I'm very impressed that you were able to build in 3 weeks time a low-latency multi-data ce

Can you list some of those tools and provide an estimate of how long they take to configure and how much day-to-day support they require?

DO, Linode, and Rackspace have lower bottom line costs, but a (much) smaller feature set which means more operational work. Especially when kicking things off, developer and operational time is often far more valuable than the cost of the

DO has a very limited API, no ability to add additional storage without resizing your droplets, and has no firewall protection without iptables being enabled. DO has its uses (I'm migrating my personal server there presently), but it&

AWS makes a lot of sense in a 24/7 environment, particularly when you are a new startup and don't have enough information (or capital!) to make educated server purchases.

Can you give an example of where mysql (the client) is terrible compared to psql (the client)? I've had the opposite experience.

I read this a lot here about probationary or trial periods and I agree that it's a great idea, in principle. However, the reality of the developer and system engineer ecosystem right now is that it's an employee's market. Go

A shell script that can spin up VirtualBox images and run puppet to provision them isn't very difficult to make Ok. Let's see the code to do that.

I use Vagrant daily. Here's an example I was working on today. I needed to spin up 5 servers, a load balancer and 2 groups of 2 backend servers. I needed to provision them with Chef, have full name resolution, and be able to access t

He's confusing kilowatts with kilowatt hours? They mean very different things. kW is a rate (kilojoules/sec) of usage (power). kWh a stackable amount (in the sense that you can stack money) of energy and is what the electric co

Yeah, the reality is it's about 3 additional commands to get going (over any other normal volume)...and a very short chef cookbook to automate it. # create a key file dd if=/dev/urandom of=/etc/mykeyfile.k
