5 Steps to Bring Your Enterprise Application into the Modern World
Modern web applications are the backbone of our digital world. Customers today expect a smooth and seamless digital experience whenever they visit a commercial website. Without high-performing applications, you risk losing customer trust and your business could suffer. That’s why it’s important to modernize enterprise applications.
Of course, keeping web apps running smoothly is easier said than done. They need to be able to handle all the traffic that gets thrown at them, without any hiccups or crashes. To ensure your web apps can handle the heat, you need to build them with the right tools and development best practices, and you need to constantly monitor and manage them, always striving for better performance and reliability.
It’s a lot of work, but with the right approach, you can make sure your apps never let your customers down. To bring your applications into the modern world, be sure to follow these five important steps.
Step 1: Use service-based architectures
Modern enterprise applications are large and complex—too complex to be handled as a single entity by a single team. Instead, multiple teams are required to develop, test, support, and operate these applications. This is not easy when the application is a single, large monolith.
By splitting the application into multiple independent services, you can assign different pieces of the application to different teams, allowing parallel development and operation. Additionally, problems can be correlated and isolated to individual services, making it easier to decide who should be called on to resolve a particular issue.
By keeping modules isolated, they can be built, tested, and operated in isolation. Scaling is not just about the amount of traffic an application receives, but about the size and complexity of the application itself. Using service-based architectures makes scaling the application easier and allows larger and more complex applications to be dealt with reasonably.
Step 2: Organize teams around services
Architecting your application as a service-based application is only part of the answer. Once you have your application set up in services, you must structure your teams around those services. It is critical that a single team owns each service, front to back, top to bottom. This includes development, testing, operation, and support. All aspects of the development and operation of each service should be handled by one, and only one, team.
There is a model for application management that stresses these ownership values: STOSA, which stands for Single Team-Owned Service Architecture, provides guiding principles on team-level ownership, providing clear boundaries between services and promoting clear understanding and expectations between teams.

Step 3: Use DevOps processes and procedures
Now that we have team organization and ownership taken care of, the next principle is to focus on the policies and practices that those teams use to build and operate their services. For modern applications, teams must make use of modern DevOps processes and procedures to build and maintain their services.
Many organizations claim that they “use DevOps,” but ultimately they do not operate their organizations in a true DevOps manner. True DevOps techniques require a complete organizational flush of all processes and systems in order to incorporate the principles of DevOps within the entire organization. You cannot accomplish this transformation by simply “creating a DevOps team,” though many organizations try.
Step 4: Use dynamic infrastructures
Customer traffic loads on your applications vary considerably. The upper bound or maximum amount of traffic your application needs to support is never accurately known. In the past, as application traffic grew, we simply threw additional hardware at the problem. But this is no longer a reasonable approach.
Simply adding hardware may be fine to help you handle expected traffic peaks, but what do you do when an unexpected spike in usage arrives? What if a message about your product goes viral on social media? How can you handle the unexpected surge from such an event? It is no longer possible to throw large quantities of hardware at an application. You never know how much hardware is enough hardware to handle your possible maximum need.
Additionally, when your application is not operating at a high volume, what do you do with the extra hardware? It’s sitting idle, a waste of money and resources. Especially if your traffic needs are highly variable or highly spiky, simply adding hardware to handle your peaks is not an effective use of resources.
Instead, you must add resources to your applications dynamically, as they are needed and when they are needed. These resources can be applied when your traffic needs are high, and they can be released when they are no longer needed. This is what dynamic infrastructures are all about.
The only way to implement a dynamic infrastructure for an application with a highly variable load is to use the dynamic capabilities of the cloud. In the cloud, resources can be added on demand, and released when they are no longer needed, becoming available for other uses.
Step 5: Maintain high visibility and deep monitoring
To modernize enterprise applications, focus on visibility. It is impossible to keep a modern application working if you do not have visibility into what your application is doing and how it is performing.
Without proper visibility into the operation of your application, you have no idea if the application is meeting the needs of your customers, or if a ticking time bomb is ready to go off and make your application suddenly unavailable. But with proper visibility, you can understand what your application is doing, how it’s doing it, and if there are any lurking issues that might impact the application’s ability to perform those operations in the foreseeable future.
Further, while using tools such as synthetic testing and infrastructure performance monitoring is important, this level of monitoring is not sufficient. You cannot completely understand how your application is performing without an internal view of its operations. This is only possible using application performance monitoring, log monitoring, and trace analysis. Ideally, you should be using an observability tool such as Datadog or Dynatrace to closely monitor every aspect of your app’s performance.
The time is now to modernize enterprise applications
Our applications are getting more complex, and becoming more intertwined with the fundamental operation of our business. As such, the expectations of our customers are growing, and the demands for reliability, scalability, and functionality from management are keeping pace. Only by following these steps to modernize enterprise applications can we make them meet the needs of our customers and our business.
