The Digital Transformation and DevOps Landscape
Digital transformation is perhaps the hottest IT trend of the early 2020s. Across industries, business leaders have pushed their technology departments to embrace transformation in pursuit of benefits such as reduced costs, accelerated time to market, improved sustainability and an enhanced customer experience. Still, some organizations have struggled to put digital transformation into practice or even agree on the definition of the term.
Digital transformation is a broad concept, but the organizations that have seen the most success with their transformation efforts are those that have focused on concrete results and tangible business value. In other words, digital transformation initiatives should not be centered on merely embedding technology throughout an organization but rather on using that technology to improve efficiency, accelerate productivity, pivot more quickly and generally meet the organization’s mission more effectively.
Although digital transformation opportunities vary by industry and organization, one common area of focus is application modernization. Across sectors, organizations are plagued by legacy applications that require resource-intensive maintenance, often through traditional “waterfall” development processes that limit flexibility and often fail to meet the needs of end users. By modernizing their legacy applications and adopting an agile DevOps approach to application development, organizations can increase velocity, shorten resolution times, improve customer satisfaction and spur innovation.
DevOps and digital transformation often go hand in hand, not only because DevOps supports application modernization but because the approach also enables the pace of change required for an ambitious digital transformation effort. By unifying their development and operations teams (and sometimes their security teams, in a DevSecOps approach), organizations that implement DevOps practices create an environment that encourages teams to collaborate and constantly iterate in pursuit of mission-critical objectives. This sort of fundamental change to systems and processes is key to true digital transformation, and it sets organizations apart from those that focus only on technology during their transformation initiatives.
Digital transformation, DevOps and application modernization all require buy-in from leadership, cultural change throughout an organization, and a considerable commitment of time and resources. But for organizations that tackle these initiatives effectively, the results are worth the effort.
Application modernization can be a challenge, but successful organizations experience valuable results.
Customer Satisfaction: Agile development methods and DevOps practices are inherently customer-centric. Applications developed in these environments are updated according to changing needs and expectations, leading to more satisfied users.
Improved Efficiency: Application modernization efforts often allow organizations to migrate resources to the cloud and leverage automated, scalable infrastructure that helps to reduce the cost of ownership.
Reduced Risk of Failure: Agile and DevOps processes rely on an iterative development approach. Continuous improvement/continuous delivery (CI/CD) tools reduce the risk of failure by uncovering performance issues earlier in the process.

At a high level, application modernization is the process of updating and improving legacy applications or building entirely new ones, with the goal of enabling the organization to better serve customers, support innovation and gain an edge over competitors. Three of the most common reasons that businesses modernize their applications are to increase velocity, improve the user experience and enhance efficiency. However, application modernization initiatives can also help organizations to achieve other valuable outcomes.
App modernization promotes efficient use of resources. Legacy applications and waterfall development processes often require teams to engage in extensive rework. By contrast, DevOps processes allow teams to rapidly release updates, and modernized apps that leverage containerization promote simplicity and automation. App modernization also can improve the experiences of users and customers.
EXTEND THE LIFE OF LEGACY APPS
Within many organizations, legacy applications are holding back business initiatives and processes, yet leaders can feel stuck because their organizations depend on these apps. Through app modernization, organizations can leverage and extend the features of their legacy applications by making them available as services via application programming interfaces.
As part of their app modernization efforts, many organizations adopt a DevSecOps approach, in which security is a foundational element of the development process. In these environments, security testing is automated, and an app cannot be pushed through to the next stage of development or production until problems are remediated.
REDUCE COSTS AND MAXIMIZE ROI
Outdated applications are expensive to maintain, not only taxing infrastructure resources but also sometimes requiring organizations to hire employees with specialized skills to maintain them. A “lift and shift” migration to the cloud typically will be very expensive over time, whereas modernizing applications for new platforms can reduce ongoing costs.
ACCELERATE CLOUD ADOPTION
While nearly all organizations are leveraging some sort of public cloud resources, many have stalled on their cloud journeys. An app modernization effort can help organizations get away from environments in which teams are deploying apps to servers that must be managed and updated.
PROVIDE IT INSIGHTS
Most organizations lack the visibility needed to glean critical insights from their IT environments, and many technology leaders don’t even know which of their apps will be the most difficult to modernize. This understanding, which is crucial to success, is the foundation for digital transformation and prioritization that accelerates app modernization initiatives.
ENABLE DIGITAL TRANSFORMATION
For many organizations, application modernization is the first step in a digital transformation journey, a cornerstone component of an overall transformation effort or both. The benefits of app modernization, such as increased automation, can help to accelerate digital transformation initiatives, with artificial intelligence often serving as the engine.
ATTRACT AND RETAIN TALENT
Many organizations struggle to attract and retain IT professionals, but companies especially have felt the impact of worker shortages in recent years. Employees don’t want to be bogged down with rote tasks, and app modernization can spur the sort of innovation that makes a company an attractive place to work.

Broadly speaking, app modernization efforts can be broken down into four stages: assessment, migration, modernization and optimization. At each of these stages, organizations must seek out and implement the tools and practices that will lead to success.
An assessment can make or break an app modernization effort. Automation is essential at the assessment stage, as humans can miss opportunities for modernization and slow down the process. A holistic assessment engagement, such as CDW’s Strategic Application Modernization Assessment, can help organizations to analyze their code, evaluate it against modernization goals, and provide a custom roadmap that leads to applications that are more scalable and easier to maintain. During a SAMA engagement, hundreds or even thousands of applications can be analyzed using CDW’s proprietary reporting and analysis technologies. To fuel digital transformation, it is important that assessments look at environments from a software standpoint rather than taking an infrastructure-centric approach.
Business and IT leaders sometimes overlook the importance of selecting the right cloud provider to host their modernized applications. Too often, organizations make this choice by default, simply continuing to use a public cloud environment with which they are familiar. But in a 2022 report on application modernization and digital transformation, IBM Consulting notes that this decision should be based on a provider’s ability to deliver necessary services. “Avoid the common mistake of considering only one hyperscaler and designing your program to fit its offerings,” IBM Consulting advises. “You’re more likely to succeed if you treat the hyperscaler as an enabler of your strategy rather than a menu of options you choose from.”
Once organizations have assessed their application environments and decided where their modernized apps will live, they must do the difficult work of creating cloud-ready applications that meet their needs. Typically, this process relies heavily on the use of containers, packages of software that are bundled together across application code, enabling seamless deployment across multiple environments. Other important tools include microservices, an architectural approach that makes development more agile by allowing each core function to be built independently; automation, which can streamline tasks such as deployment and diagnostics; and artificial intelligence, which can help organizations to mine insights from their applications.
Anyone who has worked in IT for long enough knows that the success or failure of an initiative often depends on how well it is sustained over time. Application monitoring tools can help organizations to ensure that their modernized app environments continue to perform as expected and meet users’ needs, and managed services can help reduce the burden on internal IT staffers. To support an agile, digitally transformed workplace, organizations must ensure alignment between their new application environments and their people, processes and governance. They must also closely track key performance indicators and adjust their practices over time to address changes in performance.
The 7 R’s of Application Modernization
Application modernization isn’t a one-size-fits-all endeavor. An approach that’s perfect for one application may be entirely unsuitable for another. Modernization options are often broken down into seven categories.
Refactoring involves making changes to an app’s code without altering its overall functionality. This can improve performance and reduce maintenance burdens.
Sometimes called “revise” or “rewrite,” this option results in more fundamental changes that lead to improved functionality.
Also known as a “lift and shift” migration, rehosting means migrating a workload to a public cloud environment without modifications.
With this option, an application is moved to the public cloud, but it is first overhauled to make it more cloud-native, often via containerization.
During a modernization effort, leaders may decide to leave some applications alone, especially those employed by relatively few users.
In some cases, leaders may decide that an application is no longer necessary and opt to retire it completely.
Finally, it may make sense to replace some applications with new off-the-shelf solutions. This is often a fast and cost-effective option, but project leaders must ensure that the replacement app will fully meet the organization’s needs.
Effective modernization is a powerful step toward true digital transformation that can help an organization achieve its business objectives and improve customer service.

Case Study: App Modernization
Sirius, a CDW company, helped a state courts system carry out an application modernization initiative that played a key role in its digital transformation effort. The project created a digitized system that simplified the user experience, especially for disadvantaged litigants and those without attorneys.
Before the initiative, the court system relied on paper-based procedures and in-person filing for many elements of court cases to move forward. Sirius re-engineered the judiciary’s system by designing, building and incorporating three new applications into existing applications. The transformation enabled the court system to accept electronic filing and allow litigants to appear in court using a virtual hearing platform. An online dashboard enabled court workers to review and file digital documents while reducing the complexity of documentation processing.
Ultimately, the initiative expanded the ways litigants, especially those with low incomes and those not represented by attorneys, could interact with the court. Further, enabling electronic processes simplified paperwork and provided a framework on which the court plans to add new features and capabilities.
