5.2 Building a Web Server
Agenda
- Web Servers
- Message-Passing and Listening
- Cloud Computing
- Goals
- Create a cloud-based web server
- Connect to the cloud based server and configure it
- Deploy your Sinatra application to the web server
- Run migrations and update environment / API keys
- Use Rack host your application for the world to see!
- Use DNS to assign a domain to your website
Web Servers
- We've been using web servers for a while ...
- Heroku is the primary example
- Your laptops are also web servers
- You've used Rack (Rackup) to serve applications
Message-Passing and Listening
- The internet is a series of messages
- Messages that are passed back and forth
- Web servers listen for these messages
- And react appropriately
- For example, Rackup listens on port 9292
Cloud Computing
Cloud Computing
- Companies have been investing in infrastructure
- Building out platforms that allow us to spend pennies for processing power
- They build out giant warehouses of small computers
- And we run our web servers on them
- This is extremely cost effective for us!
- But we never own the hardware
Today's Goal
Get your Sinatra project from last week online using Digital Ocean! You'll also learn how to build a web server!
Creating a Web Server
- We need to register Digital Ocean accounts
- Sign up for a new account
- GA is going to give you $50 in credits to use!
- Warning: make sure you setup a billing threshold
- Your credit card could be charged
Learning Objectives
- Register for Digital Ocean and get teh monies!@!@12
- Identify what Droplets are and how to create one
- Work with a remote server (droplet) via command line
- Get a working Sinatra app on the web for all to see!
