Legacy Modernization

Legacy Modernization: Bringing IT and Business Together

IT exists to support the business - and in best-of-class IT departments, this truism is embedded deeply into the departmental culture.

Yet in so many cases, this self-evident truth gets lost in the mayhem of building, maintaining and supporting the myriad of complicated and brittle legacy application systems that have been put together over the years to support the enterprise's business.

Legacy Application Modernization is a transformative initiative that has the potential to not only change the way IT supports the business, but to change the very nature and culture of IT.

IT Culture: Legacy Application Burden
It should be no surprise that so many IT cultures have evolved in such a way that the "customer" has become IT itself, rather than the "business users."

Upwards of 3/4 of  IT budget goes to managing ongoing operations, according to research firm IDC.  These are "inwardly" focused activities that simply keep the systems running.  And it leaves only about a quarter of the IT budget available to focus on everything else.

Legacy Application Burden and "the Business"
With only 1/4 of IT budget available for "discretionary spending", it's no wonder that so many IT departments struggle when it comes to strategically, tactically and culturally aligning themselves with the business.

The remaining 25% of budget that remains is hardly sufficient for "the business" - i.e. helping the company innovate, improve and become more competitive in the marketplace. So it should come as no surprise that some 70% of IT executives view the burden of legacy application systems is one of their top problems.

According to Gartner's recent CIO survey, the top priority for CIOs in 2012 is an IT organization that better “enables and supports the business.”

Legacy Applications, Modernization and Innovation
A different way of looking at this: typically only 25% of IT budget is available to help innovate and truly support the business.  If "Legacy Applications" could be modernized and the burden of supporting these legacy applications could be reduced by one-third, that would effectively double IT's ability to innovate and drive the enterprise forward.

In reality, this argument dramatically understates the case - by modernizing legacy applications, you not only reduce the cost associated with running and maintaining the legacy applications (thus freeing up money to be better-spent on improving the business), you can re-architect them to become modern and service-oriented.  The modernized legacy applications become more componentized, flexible, and part of an agile, extensible modern framework -  when they are broken up and re-engineered into "rationalized" re-usable components that can be linked together, integrated with other systems via a modern Integration stack.

The previously monolithic and impenetrable legacy application suddenly - previously an inhibitor of innovation, becomes a key part of innovation...becomes modern.

The issue of  legacy applications in need of modernization is the single largest barrier in most large companies to IT truly being able to become an agile, competitive asset to the business.

Legacy Modernization

Legacy Application Modernization brings IT and Business Users closer together.
Legacy Application Modernization
is a huge step forward for large IT shops, and truly helps companies tackle that "interpretation gap", and puts business users in the drivers seat.  It is a transformative experience for IT, for the culture of IT and for the overall enterprise.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
One of the most important tenets of digital transformation is that it’s customer-driven. In fact, the only reason technology is involved at all is because today’s customers demand technology-based interactions with the companies they do business with. It’s no surprise, therefore, that we at Intellyx agree with Patrick Maes, CTO, ANZ Bank, when he said, “the fundamental element in digital transformation is extreme customer centricity.” So true – but note the insightful twist that Maes adde...
Using any programming framework to the fullest extent possible first requires an understanding of advanced software architecture concepts. While writing a little client-side JavaScript does not necessarily require as much consideration when designing a scalable software architecture, the evolution of tools like Node.js means that you could be facing large code bases that must be easy to maintain.
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningf...
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Su...
You may have heard about the pets vs. cattle discussion – a reference to the way application servers are deployed in the cloud native world. If an application server goes down it can simply be dropped from the mix and a new server added in its place. The practice so far has mostly been applied to application deployments. Management software on the other hand is treated in a very special manner. Dedicated resources are set aside to run the management software components and several alerting syst...

People want to get going with DevOps or Continuous Delivery, but need a place to start. Others are already on their way, but need some validation of their choices. A few months ago, I published the first volume of DevOps and Continuous Delivery reference architectures which has now been viewed over 50,000 times on SlideShare (it's free to registration required). Three things helped people in the deck: (1) the reference architectures, (2) links to the sources for each architectur...
