The Urgency of Modernizing in the Age of Application Capital

The Urgency of Modernizing in the Age of Application Capital

We’re in the midst of a fourth industrial revolution. In today’s digital economy, the vital role of applications makes every company a technology company. Just one poor experience with an app can cause a customer to abandon that app and switch to a competitor. With cyberattacks on the rise, it’s crucial for every team member and stakeholder, in each stage of the application development process, to embrace agility and maintain a security‑first mindset.

With this mindset comes modernization. Customers and stakeholders expect certain digital experiences and, without a modern application strategy, losses are inevitable. Therefore, the call to modernize is urgent.

Enterprises are required to continuously shift, innovate, and sharpen their competitive edge in this modern age of application capital. Gartner Inc. predicts that global enterprise spending on cloud‑based software deployments will hit $557 billion in 2022. To keep pace with user and competitive demands, the development-to-testing cycles of modern apps have been significantly shortened. What initially took months now requires just weeks, days, or even hours. If the monolith-to-microservices journey isn’t fully embraced by an enterprise, the potential to lose competitive advantage – or worse, to fade into obsolescence – is evident.

Fast app development cycles are the new normal. NGINX is in the right position to simplify modernization efforts and make the journey into this new age secure and risk‑free.

The Path to Modernization

The continuous growth in application diversity is a double‑edged sword for CIOs: while it’s added necessary capabilities and helped increase productivity, fast growth has also added unexpected complexity. CIOs of larger companies are commonly struggling to keep track of hundreds to thousands of applications run by the IT organization, and a McKinsey study found that approximately 80% of CIOs have yet to achieve the agility or business outcomes they hoped would come from application modernization.

Even with initial complexity, the monolith-to-microservices shift is worth making. Its adoption by CIOs can build a more solid foundation for future app development. And by giving developers autonomy over how apps are built and deployed, the time to market is significantly faster – ensuring a competitive advantage.

Modernization builds a concrete path to new platforms, tools, architectures, libraries, and frameworks without the fear of losing everything and rebuilding from scratch. A good first step is to modernize some customer‑facing applications. Then, these applications can be optimized by software teams for distributed computing paradigms, such as multi‑cloud and hybrid cloud (this process has driven the rise of containerized apps, as they’re more portable).

Three common approaches to app modernization are:

  1. “Lift and shift” – Moves apps from on‑premises legacy servers to a cloud platform, which requires minimal code rewriting
  2. Rewriting chunks of code – Allows developers to benefit from containers and other modern infrastructures and tools
  3. Replatforming – Leverages complementary updates, replacing or modifying the app backend to focus on a cloud platform, as a middle ground between the other two approaches

Not every application must be run as a microservice. Sometimes rewriting the code is a better solution – especially if the app is tightly coupled with existing systems. It’s important to define your business’s objectives and long‑term roadmap, and then integrate a sensible approach to application modernization. Working piece by piece helps build a solid foundation for the future, along with minimizing risks.

The faster time to market must not be achieved at the expense of application security, visibility, or control, however.

Adopting these modernization techniques gives CIOs a strategic advantage over competitors, by empowering them to address disruptive trends before their business is negatively impacted. While the undertaking of modernizing legacy applications might be complex and costly, NGINX tools provide CIOs with security, visibility, and control.

The New Territory of APIs

Underlying every modern application, engineers have implemented an entire world of APIs. These APIs are in constant communication with each other to make the app function for the user – whether it be for payments, voice calling, images, geolocation, or a multitude of other functions. APIs have always played a vital role in application delivery and, more recently, APIs have moved from being part of the application to becoming its entirety.

With the rise of containers, microservices, and Kubernetes, the orientation of application architectures has shifted. Design and management of APIs has become just as important as that of data, privacy, compute, and networking. For example, in Kubernetes and microservices, decoupled functions communicate via API.

Just as we have UX, DX, and CX, we have a new term for this API Experience: APIX 2.0. Now and in the future, how APIs are experienced will become a key criteria for DevOps and GitOps teams. APIX directly impacts users – internally and externally.

In designing the crucial APIX, there are four principles:

Every time a customer accesses an app, they expect API excellence. Delivering that experience is a key part of success in modernization.

The effort towards modernization must be a conscious one. With these four principles, along with the path to modernization above, NGINX can help you modernize your application architectures with our simple and effective solutions.
