AWS just released AWS Perspective, a new tool to help you create diagrams about your AWS workload/architecture.

In a way this is long overdue. There are quite a number of companies in this space already. AWS’ version supposedly is better integrated and allows you to link to the resource directly in AWS console.

It seems to be quite useful, though it doesn’t come cheap. Someone posted on Twitter that the cost estimate comes up to USD500+ (every month) to use it.

A worm has been going around destroying unsecured databases. The intention of the attacker is not clear, but it could be similar to that of BrickerBot.

Dozens of unsecured databases exposed on the public web are the target of an automated ‘meow’ attack that wipes data without any explanation.

Woops. YouTube is down at the moment.

It’s interesting that Google chooses to display an encrypted message (presumably containing details of the error) on the client browser. This is certainly a novel way for users to report the problem without exposing potentially sensitive details (eg. file paths) to them.

YouTube is down and reports are coming in worldwide about the service being unavailable.

Update: Service is up after about 2 hours

A very good summary of the advancement of virtualization technologies used in AWS EC2. The newest instance type offered is simply AWS Bare Metal, which provides all the hardware access with little performance overhead, while still retaining the benefits of cloud – elasticity etc.
