One of the Better “Cloud Computing” Posts that I have Read

Wednesday, February 20th, 2008 by

Alex_Iskold_graphic As I strive to better understand these new emerging technologies such as “cloud computing”, I frequently find myself reading various blog articles, many professing to be the end-all definition related to the topic. It is not very often that I actually come across an article that is informative, understandable and compelling enough to warrant note.

The post by Alex Iskold is a perfect example of one of these excellent articles. An important definition from his post:

The idea behind cloud computing is simple – scale your application by deploying it on a large grid of commodity hardware boxes. Each box has exactly the same system installed and behaves like all other boxes. The load balancer forwards a request to any one box and it is processed in a stateless manner – meaning the request is followed by an immediate response and no state is held by the system. The beauty of the cloud is in its scalability – you scale by simply adding more boxes.

Some may say that this article is a bit “heavy” on Amazon as the “killer service.” But I believe his point is that Amazon has put a lot of weight behind and person-hours into their products and they will be hard to duplicate, at least for players developing “cloud” products. But some of his general comments hold true regardless of the product: “Free from the need to solve the scalability problems, startups are able to focus on the specific problems their product or service is trying to solve.”

I recommend this as a good read on what Cloud Computing is, a la Amazon, and for people really trying to make heads or tails of grid, utility, cloud and distributed computing.

Remember, Amazon’s S3 is still a “Beta”

Sunday, February 17th, 2008 by

Amazon Web ServicesI guess I could have jumped on the bandwagon and started criticizing Amazon for the issues that it had on Friday with their S3 offering. But part of me wanted to see how it all shook out, what the cause was, what would change, if anything, and how their customers would take it. According to the blogosphere, the Amazon service was down for over 2 hours (which seems to be accurate after reading through this forum thread on the Amazon developer forum).

This official Amazon AWS response clip from the forum seems to explain the outage:

Early this morning, at 3:30am PST, we started seeing elevated levels of authenticated requests from multiple users in one of our locations. While we carefully monitor our overall request volumes and these remained within normal ranges, we had not been monitoring the proportion of authenticated requests. Importantly, these cryptographic requests consume more resources per call than other request types.

Shortly before 4:00am PST, we began to see several other users significantly increase their volume of authenticated calls. The last of these pushed the authentication service over its maximum capacity before we could complete putting new capacity in place. In addition to processing authenticated requests, the authentication service also performs account validation on every request Amazon S3 handles. This caused Amazon S3 to be unable to process any requests in that location, beginning at 4:31am PST. By 6:48am PST, we had moved enough capacity online to resolve the issue.

As we said earlier today, though we’re proud of our uptime track record over the past two years with this service, any amount of downtime is unacceptable. As part of the post mortem for this event, we have identified a set of short-term actions as well as longer term improvements. We are taking immediate action on the following: (a) improving our monitoring of the proportion of authenticated requests; (b) further increasing our authentication service capacity; and (c) adding additional defensive measures around the authenticated calls. Additionally, we’ve begun work on a service health dashboard, and expect to release that shortly.

Sincerely,
The Amazon Web Services Team

Squashing Virtualization Bugs – The Dogbert Way

Friday, February 15th, 2008 by

The Dilbert cartoon continues its virtualization theme and the topic is a new “creative” way to ensure that you don’t have any bugs!

Obviously the GoGrid team doesn’t subscribe to this methodology, only to the cartoon.

Virtualization "Solutions" as defined by Dogbert

Thursday, February 14th, 2008 by

Scott Adams continues his Virtualization story, now with Dogbert as the virtualization “consultant.”

I’m glad the monkeys aren’t on the GoGrid team!
