Did you know that as of May 2024, nearly 60% of businesses worldwide are still using legacy applications?
In the first part of our blog series, we discussed the process of migrating applications to the cloud using agile principles. Now, let’s delve into the next step: modernizing these applications once they’re in the cloud.
Let’s first start with the challenges with legacy applications post migration to the cloud.
Here are some of the common challenges associated with legacy applications after they have been migrated to the cloud:
Application Modernization is about updating outdated software to meet today’s business needs and tech trends. It transforms legacy applications into valuable assets, enhancing their functionality and efficiency. It’s a necessity for businesses to stay competitive in the fast-paced digital world.
Verifying applications post-migration to the cloud is crucial to ensure their correct functioning. It helps identify and rectify any issues early, making sure smoother business operations.
Various methods and tools can be used for verification. Automated testing tools can check application performance and functionality. Monitoring tools can track system health and alert for any anomalies. Load testing can verify if the application can handle the expected user load. Regular audits can make sure compliance with security and regulatory standards.
Verification post-migration is a critical step in the cloud migration process, making sure the applications deliver the expected value.
Application modernization can leverage several technologies:

Application modernization is all about updating outdated software to meet the needs of the business today and current trends in technology. It takes the legacy applications and turns them into valuable assets, making them more functional and efficient. In the fast-paced digital world, modernization isn’t an option – it’s a necessity to keep up. Legacy systems are becoming increasingly costly to preserve, difficult to secure, and no longer capable of supporting modern-day needs such as real-time analytics and AI integration. Modernizing applications helps businesses to be agile, enabling them to quickly respond to market changes, scale efficiently, and tap into advanced cloud capabilities.
Several challenges arise with legacy applications post-migration. Performance issues occur when applications designed for different infrastructure don’t take full advantage of cloud scalability and flexibility. Data migration challenges involve complex transfers from old systems with potential compatibility and data integrity issues. Security and compliance risks arise with migration as it can introduce vulnerabilities that are not visible in on-premises. Architecture limitations occur when monolithic applications don’t work well in the cloud environments. To address these challenges, strategic modernization beyond mere lift-and-shift migration is required.
Modernizing legacy applications delivers multiple business advantages. It boosts efficiency by streamlining processes and reducing costs. Enhanced scalability allows applications to quickly adapt to market changes and demand fluctuations. User experience improves through faster response times and user-friendly interfaces. Security strengthens by updating to newer, more secure technologies that reduce vulnerabilities. Maintenance costs decrease as modernized applications require fewer resources. Business agility increases through faster deployment of new features. Finally, modernization extends the application lifespan, protecting your initial investment while adding ongoing value.
Several approaches exist and it depends on your needs and complexity of your application. Refactoring involves updating code to use modern architectures such as microservices or serverless without modifying the functionality. Re-platforming involves migrating applications to cloud platforms with minimal code changes. Rebuilding is used for creating new cloud native applications without affecting original functionality. Replacing means substitutes legacy applications with commercial off-the-shelf or SaaS applications. Each approach balances effort, cost, and benefits differently. The right choice depends on the complexity of your application, the business criticality of the application, the technical debt within the application, and your long-term application strategic goals.
Several key technologies enable successful modernization. Cloud-native databases provide scalability, resilience, and agility essential for modern applications. API gateways act as bridges between legacy and modern systems, providing unified interfaces for integrating different services. Container orchestration tools like Kubernetes manage deployment, scaling, and networking of containerized applications. Automation tools streamline the modernization process by handling repetitive tasks, reducing errors, and accelerating development. Azure App Service enables building enterprise-ready web and mobile applications. Azure SQL provides managed intelligent database services in the cloud.
Absolutely. As a Microsoft Gold Partner and Azure Expert MSP, we specialize in migrating legacy applications to Azure App Service and other Azure platform services. Our methodology has been proven to ensure a successful transition from legacy systems to cloud-based ones. We evaluate your current application environment, dependencies, and business requirements, create detailed migration plans, and prioritize applications based on business impact and complexity. We take care of refactoring or re-platforming if necessary, perform extensive testing, and use automated tools to deploy – all the while optimizing workloads, enhancing security, and reducing downtime.
Agile principles make a huge difference in the success of cloud migration using iteration and ongoing feedback. The process includes evaluating existing application configurations and identifying migration hurdles, planning migration with detailed applications and prioritizing them, designing cloud architecture according to business requirements and security requirements, developing and testing with CI/CD practices to achieve swift iterations, and deploying with automated tools for efficiency. Agile encourages shared responsibility and teamwork, enabling teams to quickly respond to problems and adjust to discoveries during migration – resulting in more efficient and successful results.
Security must be embedded throughout the modernization process. While cloud providers offer robust security measures, migrating to the cloud can leave vulnerabilities that are not apparent in on-premises environments. Key considerations include: updating to newer, more secure technologies, implementing proper identity and access management, ensuring compliance with regulatory standards during architecture design, conducting thorough security testing before deployment, and establishing ongoing monitoring and threat detection. Modernization offers opportunities to repay security debt accrued in legacy applications and apply modern security practices such as zero trust architecture.
Modernization lowers costs in various ways. Aging legacy systems need constant patching, custom support, manual workarounds, and expensive hardware-likely the cost of maintenance is increasing faster than the value of the maintenance provided. Modernized applications are not only easier to maintain, but they are less resource hungry, so the ongoing costs are drastically lower. Cloud based applications remove CapEx for infrastructure which makes the change to predictable OpEx. Automatic scaling optimizes the costs during demand fluctuations. Reduced dependency on scarce specialists that support old systems eliminates high contractor costs. All in all, modernizing existing applications is more economical than keeping legacy systems around forever.
