G Suite Vs Zimbra
Some companies wish to implement just a mailing solution with other add-ons and plugins whereas others are less comfortable with 3rd party tools. G Suite and Zimbra have similarities, yet each delivers something unique and segregates themselves as separate entities.

Zimbra Collaboration Suite or ZCS has enlisted itself in the service of providing email solution and office productivity as well as a collaborative tool for different companies to catch up with the fast-changing demographics of the corporate world. Initially, as Zimbra Collaboration Suite in 2005, after changing hands a few times, by September 2013, Zimbra formally established its firm footing as a corporate cloud solutions provider.
Two versions of Zimbra are currently available: Open Sourced version and Network Edition (Closed Loops, each having its own perks). It also comes along with a Zimbra Web Client, which supports email and group calendars for aligning mails and Video Conferencing necessary for every company to function collectively.
G Suite on the other end of the spectrum in our discussion had its inception from 2006, and became a Global Goliath, offering a wide range of applications that cater to the varied requirements of different organizations. Infiflex as Google's premier cloud services partner, helps enterprises decide upon the optimum solution that meets specific business needs.
