Unleashing Business Potential Through Application Modernisation

Whether you’re battling technical debt or preparing for a cloud-native future, modernisation is a proven path to competitive advantage.

🔍 What is Application Modernisation?

Application modernisation is the process of updating legacy software to current standards—often involving re-platforming, rehosting, refactoring, or rebuilding systems to be cloud-ready, scalable, and easier to maintain. This can include:

• Analyzing code complexity and dependencies
• Identifying critical business logic
• Mapping data flows and integrations
• Assessing test coverage and documentation

💡 Why It Matters: The Business Case

Application modernisation is the process of updating legacy software to current standards—often involving re-platforming, rehosting, refactoring, or rebuilding systems to be cloud-ready, scalable, and easier to maintain. This can include:

• Migrating monoliths to microservices.

• Moving workloads to the cloud.

• Updating technology stacks and development pipelines.

• Introducing CI/CD, containerisation, and infrastructure as code.

💡 Why It Matters: The Business Case

Application modernisation is not just an IT concern—it’s a business growth engine. The right modernisation strategy can:

✅ Reduce Costs

• Organisations typically see a 30 – 50% reduction in maintenance and infrastructure costs post-modernisation.
• Implementing feature flags for gradual rollouts
• Establishing clear success metrics
• Maintaining close communication with stakeholders

🚀 Improve Agility & Time-to-Market

• Businesses report a 40% faster delivery of new features
• Developer productivity increases by 30%, while time-to-market drops by 60%

📈 Boost Revenue

• On average, modernised systems contribute to a 14% increase in business revenue

🔐 Strengthen Security

• Organisations modernising their infrastructure see 92% faster threat detection and 21% quicker resolution

📊 Real-World Results

Here are some standout examples from across industries:

🏛 U.S. Federal Agencies

After modernising legacy applications, federal agencies saved $1.7M to $8M annually, improved uptime, and responded more rapidly to cyber threats.

🏦 Large Financial Institutions

One global bank reduced its release cycle from months to days by refactoring legacy systems into microservices and implementing CI/CD pipelines.

🧰 Our Approach at Legacy Zero

We deliver modernisation through a pragmatic, phased process:

1. Assessment & ROI Forecasting

We evaluate your legacy architecture, identify high-impact targets, and estimate business value.

We help clients shift to serverless, managed services, or hybrid cloud setups that maximise scalability and reduce ops overhead.

4. DevOps & CI/CD Integration

Automation isn’t an afterthought—our teams build robust pipelines and observability into every delivery.

5. Ongoing Support & Optimisation

We don’t stop at delivery. We provide continuous tuning, performance reviews, and cost optimisation strategies.

🔎 Focus on Metrics That Matter

We partner with clients to define and track success KPIs, such as:

• MTTR (Mean Time to Recovery)
• Deployment frequency
• Customer satisfaction scores
• Cost-per-transaction
• Developer velocity

This business-first lens ensures we deliver real, measurable transformation — not just tech upgrades.
