What is Application Modernization?
Application modernization is about updating legacy software to a new and transformed computing approach, which may include newer languages, frameworks, and infrastructure tools. This practice is often referred to as legacy modernization or legacy application modernization. It is a software development equivalent to revamping or renovating an older home to improve efficiency, safety, and structural integrity.
Rather than retiring an existing software or replacing the present system completely, application modernization majorly extends the lifespan of an organization’s application while also taking advantage of its innovations.
Key Characteristics of a Modern Application
The modern application offers increased potential for usefulness and modernization, optimizing the cost of operations while creating numerous new business models. When paired together with businesses, it creates a path of infinite possibilities and widens the digital divide between business and IT.

Why do Enterprises need Application Modernization?
There is no surprise that cloud computing has become increasingly popular in the last decade. Regardless of the size, organizations have various advantages to using the Cloud, including enhanced efficiency, lower costs, support, profitability, and more. According to one study, the worldwide Cloud computing industry is estimated to reach $623 billion by the end of 2023, growing at an annual rate of 18 percent throughout the forecast period. The biggest cloud vendor for SMBs and enterprises, Amazon Web Services (AWS), and Microsoft Azure are predicted to have a high market share. Application migration to the cloud is beneficial to the enterprise in many ways but also is a challenging task.
The need for legacy application modernization for enterprises is the need of the hour. Monolithic applications are expected in legacy applications. They have two qualities that make them attractive to modernize: they are tough to update and scale and are complex and expensive. For architectural considerations, monolithic programs are challenging to update. The complexity and integration problems overhead make it difficult and costly to add functionality to an application.
The COVID-19 pandemic disrupted how enterprises operate, but not all were affected equally or in the same ways. The organization’s risks are even more by the legacy technology that once provided the foundation for several years. Modernizing core business processes and applications has been a priority for years, but such initiatives now have much greater importance amidst COVID-19 and beyond.
Here are just a few of the key reasons for your organization to modernize your legacy applications as you move to the cloud:
- Improve efficiency – Older systems are not built for the cloud, they run in a limited capacity and provide more performance issues than actual solutions, causing long-term problems in terms of time and cost.
- Enable Innovation – Application modernization boosts innovation by allowing enterprises to focus on new ideas, processes, and workflows.
- Transform Business – Enhances your customers’ experience by transforming the end-user interface, automating manual processes, and creating new features and business models.
- Offer Greater Security – Ensures that the software or solution takes complete advantage of all the cloud has to offer in terms of security, providing your business with top safety features.
- Reduce cost – It is expensive to own and maintain the infrastructure as they incur extra costs. Organizations need a dedicated IT team to maintain a vast storage system. Therefore, investment in timely application modernization helps to avoid costs.
- Maximize ROI – Traditional apps represent investment done through decades for many businesses. Application Modernizing protects their value and investment while avoiding massive refactoring project’s the higher cost and risks.
- Mitigating risk – If businesses fail to modernize and adapt, it could put their consumers and the company at risk. Instead, companies can use modernization programs to invest in technology and process enhancements required to meet continuing security needs.
- Adopting cloud computing – Application migration cloud is the next big thing. Application modernization can serve as a springboard for moving to a contemporary, cloud-based infrastructure paradigm allowing for capacity on-demand, provision for self-service, wider consumer reach, cost savings through metered pricing.
Challenges Enterprise Face in Application Modernization
Deciding where to start, most IT organizations deal with complex landscapes with multiple technologies and platforms, unsupported environments, and legacy applications. Overlapping business processes, dependencies across applications, and hard-wired integrations are just a few of the reasons why organizations don’t know where or even how to start.
Organizations face several challenges when they attempt to modernize their applications, including:
- Inflexible, aging, and poorly integrated IT systems: It hinders an organization’s ability to innovate and deliver new products and services quickly.
- Identifying applications, data, and process redundancies – As an application portfolio grows, many organizations start to see duplication of applications for the same business process, duplicating data, and doubling maintenance for IT staff.
- Poor alignment between IT and the business strategy – Business users often complain that no matter what they ask for, IT tells them either to use the existing apps or wait until the current multi-year rollout is finished. The overall demand for mobile apps is >5x of the capacity of IT.
- Only half of decision-makers could get help from technologists with their analysis and need
- Integrating old data with new cloud applications – It is challenging to link legacy systems to new cloud-based applications; legacy systems, which constitute the backbone of many corporate companies, are typically challenging to transfer into cloud platforms.
- Time and migration cost – Cloud storage is typically considered more cost-effective than local storage. However, it is critical to precisely calculate the total cost of cloud migration, including data storage space cost.
What are the key scenarios to plan your Application Modernization?
When you start thinking about modernizing your legacy applications, the first step you should take is assessing the actual situation and questioning yourself.
- Technology: How do I know which technologies are best for my apps’ next version?
- Apps in Use: Which apps are in use and which applications can I sunset?
- Documentation: How do I plan migration when I don’t have proper documentation for existing apps
- Cost optimization: How do I optimize my cost for migration services while maintaining business continuity
- Combination of Systems: How can I leverage a combination of existing systems, new technologies, and moving apps to the cloud?
- Vision: How do I plan change management for modernizing the apps? Both on technical architecture (IT) and business process impact.

Application Migration Strategies
Application migration services involve different strategies that make the process easy and handy. There are six most vital strategies of application migration enterprises need to consider for an easy process.
6Rs of Application Modernization
Rehosting is also called the “lift and shift” strategy. You’re redeploying your current application to an IaaS environment. The strategy is usually adopted when the company wants to grow its Migration fast in a significant legacy migration scenario.
Since the program is already up and operating in the Cloud, the relative ease of moving it as-is rather than using a cloud-native approach will help add optimizations and make architectural changes.
In Replatforming, the process involves updating the program from its current platform and following the bare minimum of Twelve elements to run it on the Cloud while maintaining existing functionality. Under such a scenario, use a cloud provider’s structure rather than completely changing the application’s basic design. This method works well for apps that are useful but not crucial to the company.
Moving from the on-premises solution to a SaaS platform reduces the time spent maintaining and upgrading the system. This strategy often entails updating the latest version of the application and changing your existing price model. The repurchasing is maintained by a third party and runs outside the infrastructure.
Once you review the current architecture and compare it with the business needs, it gets clear that your migration goals have hiccups and need a partial cloud-native approach.
Once you review the environment, you can understand the application’s utility. Taking the first step of retiring products helps the team implement a cloud migration strategy that can work best for the enterprise.
Another primary application migration strategy is retaining. There are chances that you will come across data, which can be helpful to or waste. You should retain what is necessary for your company. During your analysis, you may come across apps not necessary for cloud transfer. But it doesn’t mean they are not helpful for future purposes; in this case, you want to keep them for now and use them in the future.

Azure Migration Tools
Microsoft Azure comes with different tools to help migrate data from your existing platform to their public cloud service. These include everything from sophisticated command-line programs for copying unstructured data to specialized database migration solutions.
- Azure Data Migration Assistant (DMA)
DMA aids in the migration process by examining on-premises SQL instances for compatibility with the latest version of SQL Server in Azure, or Azure SQL Managed Instances. In addition,DMA’s migration evaluation detects any roadblocks, along with supported or unsupported features, which might influence the migration strategy.
- Azure Synapse Pathway
One of the most common roadblocks to data warehouse modernization is translating current SQL code with the target platform. Usually, a database carries thousands of lines of code that have been created over many years, requiring substantial effort and money to translate. Azure Synapse Pathway addresses this issue by automating code translation to migrate current data warehouses to Azure Synapse Analytics.
- Azure Backup and Site Recovery
Azure Backup is a complete cloud-based backup solution helping to back up data from various sources, including on-premises servers, Azure VMs, Azure file shares, and more. In addition, one can use the tool after restoring data backup in the Azure location for the data migration process. For corporate applications like SQL Server, Azure Backup includes built-in application consistency. Due to this consistency, the recovered data may be quickly used to set up a functional environment with minimal effort.
Azure Site Recovery tool is entirely cloud-based for replicating data to Azure from on-premises or other cloud settings. The goal is to make Azure a disaster recovery location for workloads and workload migration through replication and one-time failover of environments to Azure.
