Thanks! I'd heard of Heroku, but hadn't understood why it might be just what I'm looking for! Cindy

Amazon Web Services (AWS) is a series of many different services, they offer a service similar to Heroku called AWS Elastic Beanstalk. AWS Elastic Compute Cloud (EC2) is usually the service people are thinking of when they think of AWS. EC2 is what is called Infrastructure-as-a-service (IaaS). IaaS like EC2 gives you a virtual machine, usually a Linux server. You maintain the Linux server, install dependencies such as Ruby, MySQL, PHP, Apache, etc, install updates, etc and are essentially the sysadmin for that server. You upload your application and keep it running on there and maintain things. With PaaS like Heroku, most of that Linux sysadmin stuff is abstracted away and largely done by automatically. Instead, you just create a simple configuration file to tell Heroku what kind of application you have (Ruby on Rails, Python, PHP, Java, etc), and maybe also what services you need (MySQL, PostgreSQL, Redis, etc) and then upload your code. The PaaS will automatically install dependencies and wire things up for you and make things just magically work for you, you don't need to worry about monitoring the server, upgrades, etc. PaaS makes it simpler to deploy and maintain an app, you don't need to worry as much about being a sysadmin. There are some drawbacks: - it might not be quite as flexible as a full VM depending on your needs - you usually must adhere to certain app development methodologies, ie: 12-factor apps http://www.12factor.net/ (but this can be a benefit also) - sometimes there is a little bit of vendor lock-in -- you often must make some minor changes to your application if you want to move to a different vendor Hope this helps :) ~James On Wed, Jun 8, 2016 at 6:43 AM, Harper, Cynthia <char...@vts.edu> wrote: > How does it compare to Amazon Web Services? > Cindy Harper > > -----Original Message----- > From: Code for Libraries [mailto:CODE4LIB@LISTSERV.ND.EDU] On Behalf > Of Andromeda Yelton > Sent: Tuesday, June 07, 2016 9:50 PM > To: CODE4LIB@LISTSERV.ND.EDU > Subject: Re: [CODE4LIB] Heroku > > I'm a freelance software developer not embedded in a library, but I use > Heroku routinely to host apps I'm developing for fun, or as a testing site, > and one of my clients deploys its production app on Heroku.
