Email Archiving Solutions Comparison: Shared SaaS vs Dedicated Cloud vs On Premise Server

Organisations looking at deploying an email archiving solution have three types of email archiving service solutions to select from:

  • Shared SaaS Email Archiving On Cloud
  • Dedicated Email Archive On Cloud
  • Dedicated Email Archive On Premise Email Archiving

This email archiving solutions comparison article aims to help organizations understand and compare the working of these three solutions. The pros and cons of each and the fit of each of these email archival solutions.

(We have assumed the use of AWS Cloud for the dedicated cloud setups.)

Essentially an organization is looking to retain a copy of every mail exchanged by all users in a secure enterprise email vault in order to recover and serve compliance requests.

Model With SaaS Archiving, Simply Subscribe, Configure and Consume the services. Provision the server and storage infrastructure on the dedicated cloud. Next, deploy the Archiving software on this infrastructure, and finally configure for high availability and security, and use this setup. With on premise email archiving, provision server and storage infrastructure in premise (bare metal or virtualized). Next, deploy the Archiving software on this infrastructure and finally configure for high availability and security.
Infrastructure No infrastructure required at your end except an Internet connection to allow transport of mail from the Primary mail servers to the Archival service on the cloud. Setup a server and storage on the dedicated cloud, in your own AWS cloud account, and install the chosen email archiving software on it. The instance type and storage capacity will depend on the number of users and the retention period.

There are two options to connect this to your Primary mail servers:

  1. Over the Internet or
  2. With a direct connection between the data center and the cloud (DirectX)
First of all, setup a server and storage in your data center, and install the chosen email archiving software on it. The server capacity and storage capacity will depend on number of users and the retention period. The users access this over the LAN/WAN.
