Cloud Demystification

Something weird and unexpected happened lately: the big Amazon cloud failed. Anyone on any media is talking about it, and everyone is communicating just this sense of surprise.

Wait a second and let’s ask to ourselves: why is it weird and unespected that AWS failed? The cloud is something human, so it has failed, as expected, and will fail again. By the way, I am sure that it failed a number of times in the past, but the failures weren’t so big to be noticed like the last big event. Continue reading

A simple SimpleDB use case

I’m happy to say that I had the chance to use Amazon AWS for a project of my customer Deltatre.

The news is particularly good because it offers a real argument in the “use or don’t use it” debate, and offers practical innovation to the company.

Technically, we decided to go on with SimpleDB during the development of deltatrePULSE (or simply Pulse) product: the idea of CTO Carlo De Marchis is to create a new distributed system that will open more the Deltatre web/sport platforms. Continue reading

Clouds Evolve: Dealing with Infrastructure Complexity

As expected, at least by me, Amazon EC2 is evolving in a more “concrete” platform good for web hosting; in fact, some time ago I received a mail from AWS announcing two new features: Elastic IP Addresses and Availability Zones (you read for sure the news also on Slashdot: Amazon EC2 Now More Ready for Application Hosting, isn’t it?)

Amazon EC2 will get persistent storage

Only a small note to let you know that Amazon is hearing us and added a new feature to EC2: persistent storage.

As a subscriber of AWS services yesterday I received an email in which Amazon announces that we “will be able to create volumes ranging in size from 1 GB to 1 TB, and will be able to attach multiple volumes to a single instance. Volumes are designed for high throughput, low latency access from Amazon EC2, and can be attached to any running EC2 instance where they will show up as a device inside of the instance…“.

The mail ends saying that the new functionality “will be publicly available later this year” and offers a link to request to join the private beta program; I subscribed it and will let you now as soon as I’ll put my hands on it.

More on the [Computing] Clouds

Recently I stumbled upon a couple of articles1,2 and, remembering my experience with EC2, I discovered that utility computing was not what I was searching for: I was searching for something that helped me without adding complexity, but I was not happy with simple web hosting offers, I wanted also complete control over my infrastructure to have the technical freedom that I could need and because, when I think about my customers’ data, I trust no one.
