G Suite & Zimbra are web-based suites that provide a communication platform to obtain maximum efficiency and productivity. However, when compared, G Suite is times ahead of the features and security levels that Zimbra has to offer.
G Suite has an upper-hand when it comes to storage space, offering 30 GB for the basic version and differs for the higher variants whereas in Zimbra it depends upon the package subscribed into. There is an upper size limit for the attachment in an email to be sent; 25 MB in case of Google and 10 MB with Zimbra. Google allows 2000 internal recipients per message and 500 external recipients per message while the limit for Zimbra is just 200.
Smartphones are the handy gadgets which nowadays every individual carries anytime, anywhere because of its portability. Mobile Device Management is the unique feature which Google offers to its customers. Zimbra does not cater any such feature in its basic versions also the premium support provided is chargeable.
For the Chat & Video Conferencing Google has its inbuilt application i.e., Hangouts while Zimbra does offer the same but it is offered through a paid third-party application. Google provides the collaborative applications like Google Docs, Google Sheets, Google Slides which renders real-time collaboration whereas in case of Zimbra these are absent. There is an online as well as offline editing feature with Google while Zimbra does not provide such features.
The uptime as guaranteed by Google is 99.9% while the uptime in case of Zimbra depends upon the server. If the server is in good health you may enjoy better services but if it is ill then you may stay back home for a few days. Google has its data in its 32 Data Centres which is encrypted and in shredded parts so the data becomes more secure and data loss is minimum. Add-Ons and Third Party Tools are available on G Suite Marketplace for Admin as well as users.
In this era of technology, do not stay back with the old methods... rather go ahead, choose Google, explore the advanced features and stay updated all the time with Google’s always connected environment.
