Physical Servers vs Virtual Machines

The IAP platform and all of its components support both physical servers and virtual machines. Virtual machines (VM) are recommended because they are less expensive and easier to manage as a solution. Moreover, performance appears to be comparable, assuming the VM hardware specs are guaranteed and not shared with other virtual machines.

Production

For production environments, all IAP components should be installed on their own individual servers to properly support high availability (HA).

Lab and Development

For non-production environments the specs may be lowered to provide lower cost options. However, keep in mind that depending on usage, these specs will need to be adjusted. For highly active developer environments with a great number of custom applications, increased CPU, memory, and disk space will be required.

IAP Server

The following table describes required IAP production server components.

Component Requirement Production ENV Lab / Test ENV Development ENV

The following hardware specs assume an IAP Server with a few custom applications. In situations where a number of custom applications are heavily utilized, or additional IAP backup storage is needed then the CPU, RAM, and disk space allocations will need to be increased.

MongoDB Server

The following table describes MongoDB server resources that are required by IAP in a production environment.

Note: The latest compatible version of MongoDB is documented in the Release Notes for the current supported version.

Alternative Lab and Development Environments

As an alternative solution a single larger VM may be used to run all of the IAP platform components. A lab environment may include MongoDB, Redis, RabbitMQ, and IAP on a single server.
