Example:
The first step in any journey is defining a destination. That means collaborating with you to define core business outcomes. This could be a reduction in security breaches, gaining the agility to release features within a defined schedule or a percentage reduction in TCO.
Example:
We assess your EC2 workloads with a view to migrating to serverless. By analysing the business pattern of demand of your web server, we determine the best course of action is to refactor to microservices to cut costs while retaining EC2 to host your web app. However, in the case of your scheduled security audits and data processing tasks, we migrate to Lambda.
We move your data processing workloads to Lambda. While successful, we noticed some lag in performance. We review CloudWatch logs and adjust memory allocation to the Lambda function. As a result of this test, we make a permanent change to this setting.
Example
After the pilot migration, the team begins a staggered rollout of the remaining services.
Example
Your TCO has been reduced by 40% through the use of microservices and serverless architecture. In addition, your application is more fault-tolerant with greatly reduced deployment times.

Map the journey:
Application portfolio assessment
______
Next, we carry out a thorough assessment of your application portfolio, analysing each element through the lens of your desired outcomes. This includes:
Inventory & Classification
Catalogue all applications and classify them by their importance to business operations and future goals
Technical Evaluation
Assess the underlying technology, integration complexity, and technical debt to identify outdated systems or inefficiencies
Business Value Analysis
Determine the criticality of each application, ensuring alignment with business goals and identifying those that no longer provide value
Performance & Risk
Evaluate performance metrics, security vulnerabilities, and compliance risks to ensure stability and security
Modernisation Strategy
Categorise applications for retention, retirement, rehosting, refactoring, or replacement based on their evaluation
Example:

Third, we define a clear path to your business deliverables. Detailing how each element of your portfolio will be refactored, replatformed, migrated or transformed.
Assembling the journeyers:
Establishing governance and cross-functional teams
______
In this step, we establish clear governance and decision-making frameworks for effective change management. This prevents stalling based on organisational blockers and guards against the security and compliance risks that may occur when adopting new technologies.
Building the right vehicle:
Establishing the new infrastructure and automation methods
______
Here we lay the foundations of your new solution, often combining IaC with DevSecOps processes to build a secure, high-velocity deployment process.
Road testing our journey craft:
Pilot migration and validation
______
Here we begin to move low-risk workloads to the new infrastructure. We then monitor and iterate based on observation.
We move your data processing workloads to Lambda. While successful, we noticed some lag in performance. We review CloudWatch logs and adjust memory allocation to the Lambda function. As a result of this test, we make a permanent change to this setting.
On the road:
Refactoring your application
______
We now have a solid foundation. We have established observability, monitoring and security processes both in the application functionality and within our governance framework.
We have established a robust deployment process and tested multiple workloads within your new infrastructure.
We are now ready to perform a staggered rollout. Testing and validating each iteration against application KPIs and the business objectives set out at the beginning of our project.
Example

Where to next?
Iterative, strategic improvements
______
Unlike some managed service providers, we’re proactive. We work with you to identify continuous improvements in line with your business objectives. We also work to keep your application future-proof as the technology landscape evolves. This includes:
Performance Tuning
Continuously optimise resources, adjust auto-scaling, and fine-tune cloud services based on monitoring data to resolve bottlenecks.
Automation Expansion
Introduce more automation in areas like backups, and security updates, and further deploy Infrastructure as Code (IaC) to streamline operations.
Adopting New Technologies
Gradually integrate AI/ML, edge computing, or Kubernetes for enhanced scalability and advanced functionality.
Security Enhancements
Strengthen security with ongoing reviews, implementing zero trust, and expanding automated security testing in CI/CD pipelines.
Cost Optimisation
Regularly review cloud expenses and apply further savings through right-sizing instances, using spot instances, or adopting new cloud pricing models.
Legacy application modernisation technologies
When we devise your application modernisation strategy, we start with your business objectives. Once we understand your requirements, we migrate and modernise, implementing a range of cloud-native technologies.
Microservices
Microservice-based architectures are inherently scalable, fault-tolerant, and flexible, allowing services to be independently developed, deployed, and scaled.
Containerisation
Containerisation packages applications with their dependencies into isolated units, ensuring consistency across environments. Containers are lightweight and portable, allowing for easy scaling and efficient resource utilisation across cloud-native environments.
DevSecOps
DevSecOps integrates security into the entire software development lifecycle, automating security checks and ensuring that code is secure from development to deployment, enabling faster and safer releases.
IaC
IaC automates the management of infrastructure through code, enabling consistent and repeatable configurations. This reduces human error and allows for quicker deployment and scaling of cloud environments.
CI/CD
CI/CD automates the integration of code changes and their deployment to production, enabling faster, more reliable releases with automated testing and minimal manual intervention.
Serverless computing
Serverless computing allows developers to focus on code while the cloud provider manages infrastructure. It automatically scales resources based on demand and only charges for actual usage, reducing operational overhead.
Observability
Observability provides deep insights into the performance and health of cloud-native applications through metrics, logs, and traces, enabling faster detection and resolution of issues.
Cloud-native security
Cloud-native security involves integrating security practices throughout the lifecycle of applications, using automated tools and practices to secure workloads across distributed cloud environments.

Application Modernisation FAQ
Monolith to microservices migration involves decomposing large, single-codebase applications (monolithic applications) into smaller, independently deployable services (microservices). Each microservice typically handles a single business function and communicates with other services via APIs.
Monolith to microservices migration and benefits:
Scalability: microservices can be scaled independently, allowing for more efficient use of resources and improved handling of varying loads
Flexibility: teams can develop, deploy, and update different parts of the application without impacting others, accelerating time to market and leading to enhanced customer experience
Resilience: a distributed system leads to better fault isolation and greater overall reliability
Composability: a microservice architecture enables a modern, composable approach
What are the benefits of application modernisation?
2555% faster lead times from commitment to deployment
Modernise your application to scale. Companies on legacy or poorly modernised architecture struggle to meet their scaling needs. They sacrifice quality to release new features quickly. They spend too much to maintain performance. And they still experience downtime in heavy traffic conditions. Modernising your application means embracing technologies like DevOps and microservices to turbocharge feature releases.
Reduce your total cost of ownership by 40%
Modernise your application to save. Companies on legacy architectures pay more for less. Their applications don’t scale down when they’re not in demand. Their resource usage is inefficient. Slow feature releases, security breaches and downtime all add to TCO. Modernising your application means implementing event-driven architectures, containerisation and scalable, secure platforms.
Reduce security breaches by 60%
Companies on legacy architectures struggle to implement correct IAMs policy. They have a large attack surface. They rely on non-automated security procedures that are prone to human error. Modernising your application means adopting zero-trust architecture and automating key security processes through DevSecOps.
