Technical requirements
To follow along with the examples in this book, you’ll need an Ubuntu Server installation to work with. In general, the following specifications are the estimated minimums to successfully install Ubuntu Server:
- 64-bit CPU
- 1 GB RAM
- 10-GB hard disk (16 GB or more is recommended)

While this may seem like a downside, all computers sold today support 64-bit operating systems, and consumer CPUs have been 64-bit capable since at least 2003.
