Infrastructure
The organization currently uses two hosting platforms to manage its services.
Platform-as-a-Service provider, with the following:
- domain registration/management
- shared web server with Apache+php environment
- shared MySQL database
- email server
- multi-domain DNS functionality
Currently all domains are registered in iPage, and they're the following:
- escng.com
- pjtracker.com
Domains in iPage have a home directory, which is the document root for any request to the domain or main subdomain (ie, www).
In the case of escng.com, we're pointing to the subdirectory containing the company website application (PHP). We're not using this settin for ptracker.com (see below).
The name servers we use for every domain are:
- escng.com: iPage
- pjtracker.com: AWS
This means that all DNS definitions for pjtracker.com are managed by AWS Route 53 instead.
By default, the DNS record set contains all the A records for all the services provided by iPage. Two of them point to the same shared web server, which will lead to the company website (set as the home directory for the domain):
- escng.com
- www.escng.com
We only added a CNAME to the devops machine hosted in AWS:
- devops.escng.com
Subdomains in iPage are actually mapped to subdirectories in the single shared web server box, and generally consist of static web pages or PHP scripts.
There are two production subdomains:
- mysql.escng.com: phpMyAdmin dashboard
- support.escng.com: ticket support application
And several with demo applications:
- areagear-backend.escng.com
- bks.escng.com
- census.escng.com
- desicon.escng.com
- forecaster.escng.com
- mecs.escng.com
- opinions.escng.com
- wtol.escng.com
Infrastructure as a Service provider, giving us complete freedom to create machines and databases as needed, managed entirely by us.
As of today, it also providers a more sophisticated domain registration and multi-domain DNS functionality than iPage.

The plan is to migrate everything to AWS to use a single platform.
