Reposting Nick's announcement from
http://nhruby.org/2009/11/8/november-meetup-ec2-and-rvm:
NHRuby is meeting for the last time this year on Monday the 16th at 7pm
at RMC Research, 1000 Market Street, Building 2, Portsmouth, NH.
Monday?! You say? Yes --- due to scheduling conflicts, the regular
meeting day for NHRuby is now to the third Monday of the month. Also,
since next month's meeting fell so close to the Christmas holiday, we
decided to skip the December meetup and resume in January. So join us
for the last meeting of 2009 for two presentations by NHRuby regulars,
Nick Plante and Brian Turnbull.
Nick will present EC2, Amazon's Elastic Compute Cloud. EC2 is a web
service which allows customers to rent virtual server instances by the
hour. The real power of EC2 is that it allows you to auto-scale your web
applications on demand. Expecting heavy load today? Fire up another web
app server or two, with no wait time for procurement, while taking
advantage of Amazon's robust infrastructure.
Making EC2 even more attractive are tools like Matt Conway's Rubber, a
set of extensions to Capistrano that allows you to script procurement
and provisioning of server instances as well as deployment of your
application itself. Need to set up a staging server? Use Rubber to
deploy a disk image, install the necessary stack and utilities, and
deploy the appropriate version of your application -- in moments -- all
automatically. In this talk, Nick will quickly discuss the basics you
need to know and then dive right into a realtime demo.
Brian will introduce RVM, the Ruby Version Manager. RVM is a command
line tool which allows us to easily install, manage, and work with
multiple Ruby environments and sets of gems. Topics to be covered include:
* Installation of RVM on Linux or OS X.
* Day to day use of RVM to switch between Ruby interpreters
* Managing sets of gems using Named Gem Sets
If you've ever been burned by differences between development and
production, you should check out RVM --- see how easy it is to take
control of your Ruby environment.
So join us on Monday, 16 November at RMC Research for the last meeting
of the year. Hope to see you there!
