Unlock Growth & Resilience with Application Migration & Modernization

Application Migration Modernization

Optimized performance. Accelerated innovation. Reduced OpEx and infra costs. Better scalability. Enhanced experience. Improved resilience. In a nutshell – growth unlocked.

Above are just a few benefits that a business can realize by moving its applications to the cloud. But many companies often fail to realize that maximizing cloud benefits demands them to go a little beyond application migration.

Not every application has been developed to run on a cloud platform. On the contrary, the majority of legacy applications are built on monolithic architecture where all data is stored in a single database. This seemingly simple approach not only has limitations in terms of size and complexity but also prevents continuous deployment, slows down start-up time, and, most importantly, is difficult to scale, which alone can deal a death blow to businesses in 2021.

The evolution of business applications: Then & Now

Before Now
Monolithic Microservices
Siloed applications Multi-channel applications
Inability to scale Unlimited scalability and elasticity
On-premises SaaS
Lesser scope of data monetization Data is the key to drive intelligence, growth
Management of servers and infra More focus on application development
Support limited platforms, form factors Support all platforms and form factors

While logically, developing cloud-native applications can solve the problem but, economically, that’s not the wisest solution a business should seek. It’s not only expensive but time-consuming, too. At the same time, not every app is replaceable. What then?

If you ask the IT leaders, they will point towards a better strategy — migrate and modernize that helps businesses regain control of their application landscape, align it with the specific business needs, and extract value from the modernized portfolio while making applications more secure. Well-architected application migration and modernization strategies often lead to an ability to innovate and excel by harnessing emerging technologies.

Before we proceed further with the key aspects of application migration and modernization, let us ask you a few questions:

Why do you want to move your legacy applications to the cloud?

Do you know

– 30% reduction in time-to-market
– Automatic infrastructure evolution are possible with Azure

Do you know

More than 30% of cloud users use Kubernetes to gain flexibility, scalability, and resilience

Do you know

You can lower TCO up to 68% achieve a 478%
3-year ROI by moving to Azure

Do you know

You can still leverage your on-prem assets and existing licenses on Azure

But survey reports show that while everyone wants to modernize their applications, not everyone is actually doing it. From the complexities involved in the process to tackling the years of operational dependence on legacy systems along with the amount of data produced, application migration and modernization constitutes an intricate process that demands meticulous planning, long-term vision, and a thorough consideration of all the factors that play a crucial role in determining success. We have identified seven key factors in the chart below that often pose a challenge for the CIOs delaying the decision-making process. Tell us what factors make you anxious about taking the big leap.

Unable to find funds for modernization

Modernization projects take too long

Why modernize when everything is working fine?

Fear making changes to core business applications

Where and when to start? What are the best practices?

How do I modernize and maintain simultaneously?

Quality of Service
Will these changes compromise service levels?

How to reimagine an application portfolio?

Majority of the IT professionals are portfolio managers — portfolios of applications built up over a period of time that can be a few months or a few decades. Today, very few organizations have the required workforce to modernize the entire application portfolio at once.

At the same time, irrespective of the size or nature of the business, every organization must reduce the size of its application portfolio in order to achieve its larger migration vision and make the strategy successful. A size that will allow the team to migrate and modernize effectively without overstretching their capabilities. A decade or two ago, two methods were being primarily followed retirement and replacement.

But as the application landscape continues to expand and evolve, the methods of modernization, too, have witnessed expansions to suit varying needs and situations of today’s businesses. Depending on the modernization objective and the problem that needs to be solved, organizations can approach modernization in a number of ways.

Azure has defined a 5 R’s approach, explained below. This 5R approach is focused on application rationalization, and each of the approaches is based on the ease of implementation, effects on architecture, technology, functionality, risk, and cost, and overall value. Let’s dig a little deeper:

The 5 R’s of Application Migration & Modernization

There Is No ‘one Approach’ For All. Choose What Is Best For You!


Moving the Application component to Azure cloud, without modifying code, features, functions

Ideal if you want:

  • Quick lift & shift
  • No code or architecture changes.
  • No risk and cost associated with code changes
  • Move important applications to the cloud quickly but don’t need immediate change application capabilities


Restructuring & optimizing existing code to remove technical debt & improve component’s feature

Ideal if you want:

  • Applications that can rapidly adapt to changes
  • High Availability
  • Apply innovative DevOps practices provided by Azure





Altering the application code to shift to a new architecture to leverage enhanced capabilities

Ideal if you want:

  • Use existing applications investments but want to incorporate new capabilities
  • Improved agility by applying DevOps practices
  • Greater scalability & want to integrate Azure capabilities into their existing applications


Rebuilding or rewriting application component from scratch. Cloud-native Application Modernization

Ideal if you want:

  • Faster development using cloud native technologies
  • Build new applications using cloud-native technologies
  • Ideal if you want to incorporate new technologies, such as AI and IoT, into applications


Replace application component with different component or new application with similar functionality

Ideal if you want:

  • Minimal administrative overhead
  • Replacement of a legacy app with more flexible cloud-based app
  • Replacing with a SaaS software
