Downtime is a thing of the past

LiveRebel 2.0 is here – Down For Maintenance? Never Again

The ZeroTurnaround are building on their successful JRebel with the second major version of LiveRebel -an out-of-the-box solution to end slow, inefficient production deployment.

Ah, those “Down for Maintenance” signs. Every developer’s nightmare. The signal that says something’s not right with the operation, often amounting to several hours work rebooting the entire thing, whilst facing the wrath of an irate manager at 3am. 

Fortunately this maligned and feared scenario could be the thing of the past with ZeroTurnaround’s newest update to hotpatching tool LiveRebel 2.0, but this time going a lot further than last year’s debut appearance.

LiveRebel 1.0 complements the Java-powered JRebel in production environments with safeguards like compatibility checks and stop-the-world updates, but the team realised that they could push the envelope much further to help developers out in a Code Red situation. LiveRebel 2.0 is like a paratrooper dropped into an existing infrastructure to start managing the production servers, with no downtime at all.

This is a revolutionary approach as the old way would be to take one server at a time from a cluster, stop it, update the application and restart it. With LiveRebel installed, it adds the ability to do rolling restarts completely automatically. All this without interfering with your infrastructure.

So it looks like inefficient production deployment is a thing of the past with a new panic button being installed for those who use JRebel’s exceptional Rebellion Technology. ZeroTurnaround promise that “every single update is an online, transactional, reversible operation that is completely automated and, in case of minor updates, instantaneous.”

 “With this 2.0 release, we are aiming to take a bigger share of the Continuous Delivery and Continuous Deployment sectors, which still have yet to see an overarching solution that can deliver what is promised,” explained Jevgeni Kabanov, ZeroTurnaround CEO and Founder. “LiveRebel 2.0 is an out-of-the-box solution to end slow, inefficient production deployment processes that often happen at 3 AM by overworked operations staff.”

“ZeroTurnaround is prepared for the challenge of changing the way operations teams think about their deployment processes, making Continuous Delivery and Continuous Deployment a highly viable option for companies,” continued Kabanov. “Having won 3 awards in 2011, averaged 35% q-o-q growth since 2009 and having gained Bain Capital as investors, I think it’s time we let the Java community at large know that we have the tools needed to improve the way organizations develop, test and deploy applications.”

LiveRebel 2.0 now supports multiple update strategies, which allows choice for users:

  • Hotpatching strategy updates the application instance in-memory, without pausing for a moment.
  • Rolling restart strategy takes each server down at a time for update, but the users don’t notice a thing as they are automatically routed to instance with their session.
  • Offline update strategy will take all servers down and do a clean restart, the user requests will still resume when servers are up.

The team are doing an anyone-can-join debut webcast of LiveRebel 2.0 on March 1st, 12 PM ET: an ideal way to learn to harness the ability of this brilliant technology. Those ZeroTurnaround boys have done it again!
