Introducing Google Message Continuity, powered by Postini

Google acquired Postini in 2007, They incorporated additional cloud-based spam and virus filtering, email archiving and encryption services into our Enterprise products. They had a vision that the power of the cloud could deliver not only increased productivity and collaboration but also security and corporate compliance tools for organizations of all sizes. Today, a new Google Postini service takes this vision of the cloud and extends it to on-premises email environments.

Google Message Continuity is a cloud-based email continuity solution—a service that helps ensure that you always have access to your email. Organizations running on-premises email systems, such as Microsoft® Exchange, can run the risk of losing email access—or even worse, their email data—during a server outage, which can impact employee productivity, revenue and even company credibility. Research suggests that a 500-person company could lose nearly $90,000 annually due to email outages*, which a continuity solution could help prevent.

Google Message Continuity works by replicating email accounts hosted on Microsoft® Exchange Servers in the cloud, using Gmail, Calendar and Contacts. If the Microsoft® Exchange Server fails, or requires scheduled maintenance or downtime, all you have to do is log into Gmail and continue regular, up-to-date email communication through Google. Since Gmail and Microsoft® Exchange are constantly synchronized with each other, you can seamlessly switch from one email environment to the other. Additionally, features such as synchronous replication that are built into Google’s architecture help ensure that your data won’t be lost at any point while being delivered to you with maximum efficiency.

Google Message Continuity can also help organizations transition to Google Apps down the road. Since Microsoft® Exchange and Gmail are always in sync with one another, there’s no need to migrate email data when eventually deploying Google Apps. With Gmail, Calendar and Contacts available, users can get familiar with these cloud services without having to abruptly stop using their regular email system.

Google Message Continuity takes Gmail’s availability and extends it to Microsoft® Exchange users, delivering on the cloud’s promise of greater reliability and security for organizations of all sizes. And with research suggesting that on-premises email solutions often face regular email downtime, this extension just seems to make sense.
