Legacy applications often struggle to cope with the increasing and constantly changing demands of modern business. Beyond the drag on innovation, maintenance can become resource-intensive, and the effort to remain compliant can lead to operational inconsistencies and potential security risks.
Whether you’re in the process of “lifting and shifting” your applications or you are already sitting comfortably in the cloud, modernisation with newer cloud-native components is essential for delivering true value from your technology investments. Modernising your applications and systems enables you to maximise the benefits of the cloud to realise greater efficiencies and innovation.
The possibilities are endless, but time and expertise are finite. Nasstar’s experienced team can help you to weigh up the complexity and risk levels associated with the existing apps against their value potential and deliver a streamlined solution with the added benefit of increased agility in a fast-moving competitive landscape.

Why Nasstar?
Starting incrementally with the less complex, but higher-value apps, our iterative approach leverages automation and best practice to accelerate time to market.
Our experts will work closely with you; building a cross-functional team to assess your application estate and understand its dependencies, function, and value mapped against what you’d like to achieve as a business. We’ll ensure that specialist knowledge, which is often as siloed as legacy applications, is embedded across your organisation.
Derisking your modern cloud environment is key to our approach and as a result, we work to continuous delivery principles and ensure that all new solutions are secure by design.
FAQs
Application modernisation involves updating older software systems to leverage contemporary development and computing techniques. This process maximises the advantages of modern cloud environments and transitions organisations away from outdated legacy systems.
Legacy applications often lack flexibility due to their monolithic architecture, where all services and features are bundled together. This structure makes it difficult to add new functionality without affecting other components, complicating testing, maintenance, and scaling efforts.
Modernising applications involves adopting new infrastructure and tools like microservices, cloud platforms, and DevOps practices, thereby alleviating the constraints imposed by legacy systems.
Application modernisation encompasses three key transformational processes:
- Transitioning from Monolithic to Microservices Architecture
- Migrating from On-Premises Infrastructure to Cloud Solutions
- Modernising IT Workflows through DevOps Practices
While each process can be implemented individually, organisations may face challenges if they stop after completing only one. This is because microservices, cloud, and DevOps complement each other. For instance, microservices perform best in containerised environments, which is a cornerstone of cloud computing. Cloud infrastructure and microservices, built for speed and resilience, are well-suited for agile IT teams that prioritise automated deployment and testing, as promoted by DevOps.
When all three transformational processes are fully realised, businesses can operate applications as microservices within a cloud environment, deploying new features efficiently through a streamlined development pipeline. This reduces costs and enhances service delivery to end-users.
Application modernisation offers numerous benefits, including improved organisational performance, accelerated time to market, and enhanced customer experiences. Additional advantages include:
Security: Leverage robust security services from cloud providers like AWS and Azure, which offer industry-leading safeguards.
Total Cost of Ownership (TCO): Reduce maintenance costs associated with legacy apps and on-premises servers by transitioning to microservices and cloud infrastructure.
Adaptability: Faster and easier addition of functionalities, allowing businesses to swiftly respond to market demands.
Improved Productivity: Independent development, scaling, and automation of microservices, combined with DevOps, enhance IT team efficiency.
Time to Market: Faster testing and deployment of smaller app changes, improving overall time to market and customer satisfaction.
Scalability: Quick adjustment of capacity based on demand, optimising resource use.
Sustainability: Reduced the carbon footprint of IT infrastructure by scaling services up or down based on usage.
The initial step in modernising is assessing the return on investment. Organisations typically start with applications that offer the highest business value and are the easiest to modernise.
At Nasstar, we collaborate with you to determine which applications should be retired, retained, or modernised, while optimising your infrastructure. We can also develop new solutions from scratch using cutting-edge tools and modern architectures.
Our approach uncovers opportunities for cost savings and flexibility. Throughout this strategic process, we help you capture long-term value and pinpoint new applications that align with your business goals.
