Solve Your Legacy Application Issues

Most organisations have applications that were built for a different era. They still work — but they’re expensive to maintain, difficult to scale, and increasingly incompatible with modern security and compliance requirements.

We help you solve your legacy app headaches with a strategic, modern approach. Using Microsoft Azure we can modernise your applications, bringing them up to date without the risk and disruption of a full rebuild. Our certified team covers the full stack: .NET, Blazor, React, Angular, Azure services, and DevOps — with AI tooling to accelerate delivery.

With Transparity’s Azure application development services, you can reimagine your core applications and make them truly fit for a modern, scalable, cloud‑native world.

Our Approach to Application Modernisation

We start by getting to the heart of why you want to modernise — whether it’s cutting costs, improving performance, tightening security or unlocking scalability. And we only change what actually needs changing. Sometimes it’s a full rebuild; other times a smart refactor or simple cloud migration does the job. 

Scoping & Design

We map out a clear, tailored path to the cloud. That means setting up secure environments, building Infrastructure as Code, and putting CI/CD pipelines in place so your modernised apps deploy cleanly, scale easily and take full advantage of Azure from day one.

Software Modernisation

Then we get hands‑on. Using cloud‑native engineering practices, we transform legacy systems into agile, scalable modern apps. Every sprint is documented and reviewed so the work stays aligned with your goals and moves smoothly toward a cloud‑ready outcome.

Testing

Quality matters, so we test thoroughly — using a mix of manual and automated methods like BDD, Gherkin and Playwright. This ensures every refactored app is robust, meets requirements, and performs flawlessly during user testing.

Handover & Ongoing Support

Finally, we hand everything over the right way — mentoring your team, sharing documentation and offering tailored ongoing support. Whether you need Azure app development services or full managed services, we keep your modernised apps scalable, secure and future‑proof long after go‑live.

“I’m impressed with their level of technical ability. Their staff is top-notch and they have a thorough understanding of a wide range of technologies. They leveraged their skills to enhance the performance of our products.“

The Advantages of Legacy Application Modernisation Services

Today’s market moves fast—and with new cloud‑based products popping up all the time, it’s getting harder for older systems to keep up. What used to be a brilliant solution has slowly become a legacy headache, weighed down by quick fixes that now cause slowdowns, glitches, and missing functionality.

As tech expectations skyrocket—smoother experiences, faster transactions, bigger data needs, tighter security—outdated systems can quickly hold your business back. In short: sticking with legacy tech could cost you your competitive edge.

Azure Application Development Services

Transparity’s azure application development services leverage Azure and its development platform’s cloud-native ecosystem, offering a comprehensive suite of tools designed to empower modern businesses. Together, these tools enable organisations to achieve greater agility, scalability, and cost-efficiency, while ensuring high availability and compliance for mission-critical workloads in a rapidly evolving digital landscape.

Core services like Azure Kubernetes Service, Azure Container Apps, and Azure Functions enable seamless deployment and scaling of microservices and serverless applications.

Solutions such as Azure Cosmos DB, Azure SQL Database, and Azure Storage provide robust, scalable, and secure options for managing data—supporting everything from high-throughput transactional workloads to globally distributed applications.

Azure App Service accelerates the creation and deployment of web and mobile apps, allowing for rapid innovation without the burden of infrastructure management.

Azure Serverless Computing

Serverless Computing saves money by allowing applications to be developed and deployed with no reference to actual servers. Our Azure Development team can help with:

  • ASP.NET Web API – develop REST APIs for web applications and other services to consume.
  • Blazor/Angular/React Single Page Apps – develop single-page applications (SPA) by dynamically rewriting the current web page with new data from a server, instead of loading an entirely new page.
  • Azure App Services – build scalable web applications to give the end-user access to the back-end data and logic.
  • Azure Storage – replace on-premises file shares with scalable and cheap storage in the cloud, opening access to APIs and end-users as needed.
  • Azure SQL Database & Azure Cosmos DB – providing seamless scaling and global replication for your SQL and non-SQL data.
  • Microsoft Entra, Entra External ID and Azure B2C  – authorising access to your applications and services in the cloud with Microsoft’s best practices in security.

Azure Containers

Azure also supports Containers, such as Docker, which are the latest form of virtualisation. These lightweight virtual machines contain parts of larger apps and can be rapidly deployed and managed independently to deliver microservices architecture.

As an Azure development house, Transparity uses containers to isolate software from its surroundings and provide non-conflicting environments across teams.

Our Azure development team can help you with:

  • Azure Container Registry – store and manage container images in a central registry.
  • Azure Container Instances – quickly launch containers with hypervisor isolation.
  • Azure Kubernetes Service (AKS) – provision clusters of containers using a highly available, secure and fully managed Kubernetes service.
  • Azure Container Apps – a fully managed serverless container service.
  • Docker – use a leading container platform that is truly independent between apps and infrastructure.
