Everyone's heard the term, but what exactly are containers?
The software enabling this
technology comes in many forms, with Docker as the most popular. The
recent rise in popularity of container technology within the data center is a direct result of its
portability and ability to isolate working environments, thus limiting
its impact and overall footprint to the underlying computing system.
To understand the technology completely, you first
need to understand the many pieces that make it all
possible.
I've written about and trained folks on various DevOps tools through the years, and
although they're awesome, it's obvious that most of them are designed from the

configuration management programmatically is the whole point.
In recent years, there has been a trend in which data centers have been
opting for commodity hardware and software over proprietary solutions. Why

familiar with bash's array feature.
Although not as powerful as similar constructs in
the P languages (Perl, Python, and PHP) and others,
they are often quite useful.
