Deployment is the act of taking a piece of software and installing it onto a server, applying configuration as necessary.

A deployment tool is a package manager. Various OSes use rpm, deb, msi, dmg, etc. Some languages provide their own methods (CPAN, RubyGems, PyPi, NPM, etc). At its heart, it's a tarball with metadata.

So, rex is not a deployment tool. It is a provisioning tool. And a poor one, at that.

Chef, Puppet, Cfengine, Ansible, and Salt are NOT deployment tools. They are provisioning tools. They ensure that certain packages and scripts have been executed on the target server.

Vagrant is NOT a deployment tool. It is a virtualization manager. (It's actually a sugar layer on top of other virtualization managers.)

Just because these tools are written in Ruby doesn't make them poor. Ruby is an excellent language to do OS work in, much better than Perl.

My criteria for good software:

Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


Problems? Is your data what you think it is?
