Assessing your options for conducting a cloud migration initiative from New Relic’s Enterprise Guide to Continuous Application Modernization.
Keep in mind that modernization strategies should be iterative: You can start with a more basic approach, reap the initial benefits, and then repeat this process by progressively adopting more advanced modernization tactics that offer additional advantages. Each modernization cycle should be measurable and should also support the culture, process, and technology changes that move your company through its digital transformation.
Step 3: Gather data to inform your decisions
The goal of this step is to get a clear understanding of each application and its interdependencies. For example, taking baseline measurements will help you understand how each application performs in its current environment. This knowledge, in turn, gives you the foundation for making informed decisions as you create your modernization roadmap. This is a far more effective approach than relying on guesswork, anecdotes, and “gut feelings” to understand how your application functions now and whether modernization would improve it.

Step 4: Weigh the tradeoff between modernization options
Simpler options (such as rehosting) generally offer lower risk and lower potential upside than more advanced approaches (such as refactoring). But every application and every business scenario offers a unique mix of risk and reward—and it’s critical to identify and assess the risks involved for each application before you settle on an approach to modernizing it. There may be situations, for example, where it’s useful to modernize a component from an application —such as a database—while leaving behind the rest of the application.
In general, you’ll need to consider the time, cost, and complexity of each modernization approach against the potential value of any improvements and outcomes you can achieve (including agility, scalability, reliability, performance, better customer experience, reduced costs, reduced management efforts, and more).
Step 5: Follow proven best practices
Adopting proven best practices, such as those found in the AWS Well-Architected Framework (WAF), can go a long way toward minimizing the risks and maximizing the benefits of an application modernization initiative. The WAF, which consists of five pillars—operational excellence, security, reliability, performance efficiency, and cost optimization— was developed specifically to help companies build secure, high-performing, resilient, and efficient cloud infrastructures for their applications. Each white paper in our modernization series also shows how to apply the WAF pillars to a specific modernization option and also explains how to use New Relic to monitor and measure the impact of your modernization initiative.
Learn more about using New Relic to instrument each of the five WAF pillars with our ebook, Cloud Done Right: The AWS Well-Architected Framework Instrumented by New Relic.
Step 6: Set up your team for success with a strong DevOps culture
DevOps teams, and the culture to support and empower those teams, are a make-or-break requirement for any modernization initiative. DevOps equips your teams with all of the key traits—from speed and agility to resiliency and scalability—they’ll need to succeed at developing modern applications.
DevOps teams, however, often struggle to stay ahead of the growing complexity within today’s application environments. Teams often deal with hundreds or even thousands of moving parts—some of which grow and change moment by moment, even as teams work to understand and troubleshoot them.
The good news is that you can turn to proven best practices for building and sustaining DevOps teams—giving them the mindset, strategic vision, and supporting culture to deal successfully with this tsunami of change.
Read our white paper, Preparing for the Next Phase of DevOps, to understand the state of modern DevOps, to discover why complexity poses a major challenge for DevOps teams, and to learn what your organization can do to cut through complexity and achieve the agility you need to win with modern development methods.
Ready, set, modernize!
Modernizing your applications will always involve making important—and potentially risky—decisions. Using observability for a data-driven approach based on proven best practices can go a long way toward reducing risk and optimizing the outcomes of your modernization initiatives. That’s why New Relic partners with AWS—upholding our commitment to helping you make informed decisions about your organization’s journey to the cloud.
