Project Always On

By | September 6, 2013
One of the projects we are working on at Zimbra is project "Always On". The goal is very simple: Email and collaboration should be "always on" for end users. It's no secret that email is the number one tool used for business collaboration. Project Always On solves key issues related to operating a platform built to be the central hub of collaboration delivered as a cloud service. Our Design Goals We started with some very basic design goals based on what we believe are the key attributes of a cloud service. Inherently resilient to failure Scaling should be elastic based on workload demands The software can be enhanced without service disruption Efficient usage of commodity hardware resources As we thought about these design goals, we arrived at a few technical capabilities and basic architectural requirements to achieve them. No single points of failure in the application components Separating the application code from the data Distributing state information across commodity storage Automatic failover of application and data storage components Automatic load balancing of client requests across the application and data layers How Zimbra is Changing There is so much of work that goes into re-architecting your software, so we've been doing this over several phases.… Read more »

VMware Zimbra Enterprise Messaging Embraces NetApp NFS

By | March 4, 2011
Today’s messaging and collaboration systems must be highly reliable: end users need access to email and calendaring 24 hours a day, 7 days a week. Designing a reliable messaging and collaboration environment entails choosing the proper storage, server and operating system. Many of us employ storage area networks (SANs) to provide that storage reliability, but SANs require specialized expertise to manage. Today, VMware Zimbra is releasing a new whitepaper detailing our testing of Zimbra with support for NetApp Network File-based Storage (NFS) and VMware vSphere, a significant competitive advantage over other email and collaboration systems. Zimbra 7 takes a new, innovative approach towards messaging and collaboration. File-based storage gives customers additional flexibility, scalability and cost savings when designing and deploying a messaging system. Listed below are just some of the benefits of using file-based storage for your enterprise email deployments:… Read more »

Extending Zimbra with Server Extensions

By | April 27, 2010
Zimlets and the ability to extend the Zimbra Web Client is a pretty widely known capability. But did you know that Zimbra also has a framework that allows developers to extend Zimbra server-side functionality? Zimbra Server Extensions provide a mechanism to add functionality to the server in lieu of modifying web.xml and other web server configuration files. By implementing a Server Extension, you can inject or in some cases, intercept, server-side functionality. Some examples include: Handling authentication requests against a user store different than the built-in Zimbra LDAP user store. Server Extensions provide a way to "plug-in" your custom authentication mechanism.… Read more »

Revisiting the Zimbra REST API…

By | February 3, 2010

What methods are available? How does the Zimbra REST API compare to the Zimbra SOAP API?). So I thought it would be good to revisit the topic.… Read more »
