Platform Deployment Options

From AgileApps Support Wiki

This section describes deployment options that increase scalability and reliability.

Multiple Application Servers
Instances of the platform can be deployed on different servers to improve response times.
Separate servers for Apache httpd
When the Apache httpd server is used to serve static content, the Apache httpd instances can be deployed on separate servers, while platform instances run on their own servers. Learn More: Installing and Configuring Apache for Use with the Platform
Separate Messaging Server
To further improve performance, the Messaging Server can be installed on a standalone system. Or it can run the same system as an appserver.
Web App Accelerators
Web Application acceleration services like those provided by Akamai can also be used to improve response times and throughput. Learn More: Web Application Accelerator.
Multiple memcached servers
The MemCache Daemon can also be run on one or more separate servers. In addition to the performance improvement, that configuration makes it somewhat easier to add application servers to scale capacity later. Learn More: Configuring memcached
Certificate-authentication Server
Adding a certificate-validation server to the network architecture, allows the platform to be accessed by browsers or by REST APIs without a login step, by supplying an identifying certificate.

Separate Database Server
Running the platform and the Database on different servers is highly recommended for a production deployment. Learn More: Configuring MySQL to Run on a Separate Server
Separate Servers for Backend Processes
The backend processes used by the application server can be (and should be) deployed to at at least one "backend server" to minimize response time in the customer-facing server they would otherwise be running on. Beyond that, heavily-used services can be deployed to servers of their own, to maximize performance. Learn More: Managing Backend Services
