The Value of Unlocking Legacy Applications
By Craig Marble, Sr. Director, Legacy Modernization Services, Astadia
There's an impulse to roll one's eyes and think of legacy applications as problematic, almost by definition. They're old, and they may run on hardware that's slower or more difficult to maintain. But in many instances, that's too simplistic an assessment. Would you respond the same way to an older bottle of a Grand Cru Bordeaux?
For many state and federal agencies, the data and the processes associated with legacy applications take on a similar rarified value. There may be years of insights bound up in that older database, processes that have been tried, tested and streamlined over years of use. That data and those processes may be an essential part of what enables an agency to meet its stakeholder needs. Rather than viewing it as a creaky old system that should be replaced, it's worth looking instead at modernizing how users interact with it.
What do I mean by this? Let's say a legacy application has for years been tracking and managing configuration and repair histories for an aging line of small naval vessels. What if the service members responsible for ship repair could now point a cell phone camera at a component on the vessel that has been misbehaving and instantly pull the service history of that component from the data center? Legacy applications don't need to be rewritten from scratch to enable this kind of real-time recognition and remote data retrieval. It works because the way users interact with the existing data and processes has been modernized.
In this instance, the technician might be using a phone or some other device (think along the lines of HoloLens technology) that could capture visual information on site. The device would transmit the information about the component to a cloud-based application that would interpret the image data and formulate a query based upon needs. The cloud application would query the legacy application, gather a response and then provide the technician with the information required in a useful format - a schematic diagram, a repair history or procedure or whatever had been requested.
There are clear advantages to a modernization strategy of this kind. An agency can continue to derive value from the investments already made in data and processes. At the same time, more modern innovations can help expedite resolution. In the example of the component repair on a naval vessel, a technician might be able to identify a problematic component, pull all the information from the legacy app required to repair it and get it up and running again within moments. Previously such a repair might have been more costly and time consuming.
Modernization is not limited to adding an image capture system, either. Modernization can take many forms, and that's part of what makes it so exciting. An emergency management agency, for example, might pull data from a legacy application into a cloud-based virtual reality app that can show first responders where water pipes or electrical lines should be in a neighborhood that has been ravaged by an earthquake or flood. Thinking about how legacy applications can be modernized (rather than rewritten), sparks innovation and formulation of new ways of interacting with constituents or new ways of capitalizing on those assets to add value.
In this way, modernizing a legacy system can save significant amounts of money, even as it reduces the risks that always accompany a large system rewrite. But those reductions are not the best reasons to look at modernization. Better reasons focus on the ability to incorporate innovation while building on the assets already in place. An agency's IT organization can play more of a consulting role. It can implement new ways to meet the needs of stakeholders - both inside and outside the agency - who can benefit from interacting with existing information and processes.

The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...

With billions of sensors deployed worldwide, the amount of machine-generated data will soon exceed what our networks can handle. But consumers and businesses will expect seamless experiences and real-time responsiveness. What does this mean for IoT devices and the infrastructure that supports them? More of the data will need to be handled at - or closer to - the devices themselves.

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

Web Real-Time Communication APIs have quickly revolutionized what browsers are capable of. In addition to video and audio streams, we can now bi-directionally send arbitrary data over WebRTC's PeerConnection Data Channels. With the advent of Progressive Web Apps and new hardware APIs such as WebBluetooh and WebUSB, we can finally enable users to stitch together the Internet of Things directly from their browsers while communicating privately and securely in a decentralized way.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.
