Amazon S3 Design Principles

The following principles of distributed system design were used to meet Amazon S3 requirements:

Decentralization: Use fully decentralized techniques to remove scaling bottlenecks and single points of failure.

Asynchrony: The system makes progress under all circumstances.

Autonomy: The system is designed such that individual components can make decisions based on local information.

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost
