Stratus everRun®

Affordable, easy-to-manage software to support your always-on applications

If you were asked to come up with a list of applications that absolutely had to be continuously available, odds are that you would not struggle to build the list. Most likely, your list has grown over the last few years—and it continues to grow. At Stratus, we’ve seen the need for always-on applications become more pervasive across all markets, and all industries globally. But what’s driving this demand? The obvious reasons are financial losses and long-term damage to an organization’s reputation when businesses go down.

In today’s competitive climate, organizations must operate and deliver top-notch services 24/7/365, externally and internally. If your service goes down in manufacturing, your lines cannot function and productivity and revenue take a hit; in building security and automation environments, the premises and individuals that need to be protected are at risk from internal and external threats; in healthcare and public safety, lives are at risk. And there are other considerations driving the need for continuously available applications, including the constant struggle organizations face to comply with regulations, mitigate disaster and plan for business continuity. All these factors contribute to an increasing demand for reliable, continuous availability of your most critical applications, with no tolerance for intermittent service disruptions and associated lost revenue.

What exactly is “availability”?

The term “availability” is a characterization of how reliably a computing system can function and perform the tasks it was designed to run. It is measured as a percentage of time within a given time span (for instance, a year) that your applications are operational and accessible to users. But not all availability is created equally. Different solutions provide different levels of availability:

  • Backups and restores: Basic backup, data-replication, and failover solutions and procedures are in place to recover services in the event of a failure or disaster. These solutions do not prevent downtime but focus on recoverability which translates into 99% to 99.9% availability. Being down from 8 hours to 4 days can cost from $2M to $23M.
  • High availability: Typically implemented through clustering, these solution applications are accessible a very high percentage of the time. Users perceive little or no perceived interruption if there is a failure and high availability translates into 99.95% to 99.99% availability. Being down from 1 to 4 hours can cost $230K to $1M.
  • Continuous availability: Even if there were to be a failure, application operations are not interrupted. Downtime is eliminated and data is not lost in the event of a failure or localized disaster. These solutions focus on preventing downtime which translates into 99.999% availability. Being down 5 minutes or less, limits your risk to $23K.

“The everRun solution for P2000, offers us the extreme level of availability we need for our critical access control system at the airport.”

Achieve continuous application availability with everRun

Stratus everRun simplifies the process of making applications available—not just some of the time, but all of the time. everRun’s software based solution links two servers together via a virtualization platform that pairs protected virtual machines to create a single operating environment. The entire application environment, including data in memory, is replicated by everRun, ensuring applications continue to run without interruption or data loss. If one physical machine should fail, the application continues to run on the other physical machine without any interruptions or data loss. If a hardware component fails, everRun substitutes the healthy component from the second system until the failed component is repaired or replaced.

Optimize application environments to achieve maximum availability

With everRun, you are able to realize the value of continuously available applications without the configuration complexity that comes with traditional solutions. There is no need to design your applications to be HA aware, or to manage the connectivity between servers or configure shared storage where data resides.

everRun enables you to consolidate physical servers and reduce your operating costs while protecting your applications from downtime. everRun supports a wide variety of commodity, Intel-based x86 server hardware.
