      <h1 class="w3-text-teal">Pets, Cattle and Swarms</h1>
      <p>The internet age can be loosely defined as having three ages - we'll look at each and see how development practices have evolved to the swarm.
         <a href="http://www.slideshare.net/gmccance/cern-data-centre-evolution">This paper</a> from <a href="https://home.cern/">CERN</a> (the birthplace of the Web) seems to have originated the naming strategy</p>
      <h2 class="w3-text-teal">The Age of Pets (1960s - 2013)</h2>
      <p>Eary internet servers were well known. They may have sat under your desk, or in a rack in a nearby building. You knew what machines ran what services and if a machine broke the service went away until you lovingly replaced the faulty memory, disk or what ever.
      People really cared about those machines!</p>
      <h2 class="w3-text-teal">The Age of Cattle (2013 - 2016)</h2>
      <p>The big problem with lovingly caring about your pets is that it does not scale well. If you have hundreds or thousands of servers then on the law of averages you'll have some that are poorly (or dead!). If you wish to tend them all you'll be very busy.
      The battle cry went out to "treat them as cattle not pets!" The basic idea here is to script the build and deployment of the servers. if one is unwell, kill it off and bring up another with the same configuration.
        A lot of software emerged to enable this automation of infrastructure, cf <a href="https://www.chef.io/chef/">Chef</a>, <a href="Puppet">Puppet</a> and <a href="https://www.ansible.com/">Ansible</a></p>
      <h2 class="w3-text-teal">The Age of the Swarm (2016 - ??)</h2>
      <p>Now we're looking at the datacentre as the computer. Your functions can be run across many machines, without you needing to be aware of the issues involved in scaling it out, mitigating against failure etc. (Well, almost)</p>
