The battle cry of IT brinksmanship, "If it ain't broke, don't fix it," means that risk has triumphed over cost. This fate is commonplace for legacy applications which can be found sitting on an outdated/unsupported box, running on ancient OS sporting a "Do Not Touch" sign.
Not important enough to fix; too important to fail. These applications are at risk of failure. And everyone knows it.
AppZero offers an alternative that changes the risk/cost math by eliminating the risk at a slashed cost/effort - with no re-engineering or coding required.
Over the last few years, we have helped a number of significant IT operations use our application virtualization solution to migrate their legacy Solaris applications onto newer systems that are reliable and powerful systems. Prior to learning about AppZero, these organizations lived with risk hunting spare parts for their hardware systems from Ebay and Craigslist - sites that, like the old buffalo grounds, are now hunted-out. At this point, risk becomes probability.
Most people reading this article understand that the evolution of Solaris brought big changes between version 7 and 8. So why are so many applications still running on 2.6?
Because 2.6 was a very popular Solaris version, many customers invested in applications - both mission-critical/enterprise and line of business/departmental. As the Solaris operating environment grew, most mission-critical applications were moved to the more current versions of Solaris through application vendor upgrades, patches, etc. However, there were many organizations that had built custom applications, or had applications for which the vendor was no longer in business, and they had no easy way to migrate to the newer Solaris versions. Or the applications were not deemed ‘mission critical'. Enter the "wait and see" or "if it ain't broken" approaches.
Fast forward to today. We at AppZero know firsthand that there remain a sizeable number of legacy Solaris applications which continue to be supported by some of the largest and most recognizable companies. In our interactions with these organizations, we have observed an odd mix of magical thinking and fatalism. It has always worked; we will deal with it when it happens.
What is the truth? Sun/Oracle made significant efforts and investments to provide backward compatibility for their customers. They are one of the few vendors who have made significant investments in order to try and make it easier for their legacy clients to easily migrate to more current Solaris environments. The challenge for organizations running Solaris environments of the 2.6 era is that their applications usually don't meet the criteria to be covered within the Oracle Binary Compatibility Guarantee.
They had legacy clients in mind when they originally developed Zones within Solaris 10. For any organization running Solaris 8 or 9 applications, it's a simple matter to put them into branded zones on Solaris 10 to enjoy the benefits of the newer OS and hardware systems. What many people fail to understand is that the branded zone approach is not an option for the older Solaris 2.6/7 applications.
Here's where AppZero comes in. Our software encapsulates your old 2.6/7 application, packaging enough of its OS eccentricities that it will ‘feel' completely at home when it is picked up and placed on the bright and shiny Solaris 10 OS and box. Instantly running. Risk and cost dramatically cut.
If it ain't broke .... check out AppZero's solution and ask about our "no app left behind" service.
I am always looking for a way to communicate better and cut to the heart of the discussion. So, if you have thoughts on this subject, drop me a line at [email protected], or tweet us at @appzero_inc. www.appzero.com.

Now that the world has connected “things,” we need to build these devices as truly intelligent in order to create instantaneous and precise results. This means you have to do as much of the processing at the point of entry as you can: at the edge. The killer use cases for IoT are becoming manifest through AI engines on edge devices. An autonomous car has this dual edge/cloud analytics model, producing precise, real-time results. In his session at @ThingsExpo, John Crupi, Vice President and Eng...

There are 66 million network cameras capturing terabytes of data. How did factories in Japan improve physical security at the facilities and improve employee productivity? Edge Computing reduces possible kilobytes of data collected per second to only a few kilobytes of data transmitted to the public cloud every day. Data is aggregated and analyzed close to sensors so only intelligent results need to be transmitted to the cloud. Non-essential data is recycled to optimize storage.
