Cloud modernisation strategy for enterprises: how to get started?

What is cloud modernisation?

This includes rearchitecting legacy systems, adopting microservices, integrating DevOps practices, utilising containers, and embracing Infrastructure-as-Code to improve scalability, flexibility, and speed.

It also involves incorporating multiple cloud providers and private cloud environments to enhance resilience, avoid vendor lock-in, and optimise resource allocation.

To truly unlock the potential, organisations must dig deeper on cloud infrastructure, examining and refining their underlying architecture to maximise efficiency and performance.

This transformation is far more than a simple lift-and-shift of old systems into the cloud. It involves fundamentally rethinking how IT services are built and delivered, with the goal of achieving greater automation, efficiency, and innovation.

Cloud migration & modernisation in numbers

By modernising your cloud environment and digging deeper into cloud capabilities, you can reduce costs, improve performance and availability, enhance security, and align IT infrastructure with business goals. Ultimately, cloud modernisation becomes a catalyst for digital transformation across the company.

Enterprises which, among other things, delay cloud modernisation often face a failure rate of up to 70% in general transformation initiatives due to lack of clear strategy, outdated systems, or misalignment between IT and business goals.

Accenture points out that cloud migration can reduce your TCO (Total Cost of Ownership) by 40%. What’s more, 65% of IBM’s survey respondents state that cloud computing allowed them to reduce TTM (Time to Market). McKinsey’s research shows that organisations adopting cloud-native architectures can achieve an IT overhead costs reduction by at least 30-40%.

A great real-life example is Capital One, a leading US financial institution that embraced full cloud modernisation by moving to AWS. As a result, they changed their data centre footprint from 8 in 2014 to 0 in 2020, cutting infrastructure and maintenance costs significantly. They also reduced their processing time for check clearing app by as much as 80%, greatly improving their analysts’ productivity along the way.

At Future Processing, we achieved a 90% reduction in deployment time and doubled the operating speed through a large-scale migration to the cloud for one of our UK insurance clients. Another cloud success story with TrustMark shows how we reduced their cloud costs by 72% thanks to a seamless transition within a tight 20-day timeline. TechSoup now saves up to 50% a month thanks to our AWS Cloud saving plans.

How can businesses reduce costs during cloud modernisation?

As you can see above, cost control is one of the primary motivations behind cloud modernisation. To maximise savings while modernising, businesses can adopt a number of best practices:

• Right-size cloud resources: analyse workload performance to ensure you allocate only the necessary compute, storage, and networking capacity. Avoid over-provisioning and reduce waste.
• Leverage pricing models: reserved instances for long-term predictable workloads and spot instances for flexible tasks can drastically reduce costs.
• Use auto-scaling and serverless computing: dynamically scale up or down based on real-time demand, preventing unnecessary usage and improving efficiency.
• Adopt FinOps principles: financial operations frameworks help create visibility into cloud spending and align financial accountability with engineering and operations teams.
• Outsource operations via managed services: using cloud provider services for databases, storage, and monitoring allows businesses to reduce infrastructure management overhead and staffing costs.

Modernisation also enables the adoption of more energy-efficient technologies and consolidated infrastructure, further lowering the TCO (Total Cost of Ownership) over time.

To assess the effectiveness of your cloud modernisation efforts, you have to track relevant performance and cost-efficiency metrics, such as:

• Cost per transaction – the average cost of delivering a single user action or business process in the cloud.
• Cloud utilisation rate – how effectively allocated resources are being used.
• Time-to-deploy vs. legacy systems – how much faster new features or services can be deployed compared to your previous infrastructure.
• Cloud waste (%) – the proportion of unused or underutilised cloud resources, often due to over-provisioning or lack of governance.

What are the other benefits of cloud modernisation?

Beyond financial optimisation, cloud modernisation delivers numerous strategic advantages, such as:

Lower operational costs and improved resource efficiency

Cloud modernisation greatly enhances operational efficiency by optimising infrastructure and introducing automation. This reduction in manual processes leads to lower ongoing maintenance efforts and better resource utilisation, ensuring a higher ROI.

Greater scalability and flexibility

One of the most compelling benefits of modern cloud infrastructure is its ability to rapidly scale according to business demands.

Unlike traditional on-premise systems, cloud resources can be dynamically adjusted to meet peak demand, such as during seasonal sales or unexpected surges in activity. This flexibility also enables businesses to quickly add new capabilities without additional hardware, ensuring growth is not hindered by infrastructure limitations.

Enhanced security and compliance

Cloud providers implement robust security measures such as end-to-end encryption, automated threat detection, and multi-layered access controls. These tools help protect sensitive data and ensure compliance with industry regulations like GDPR, HIPAA, and others. Continuous monitoring and automatic security updates reduce the risk of breaches and provide proactive risk management.

Modern cloud security strategies also embrace Zero Trust Architecture, which assumes that no user or system, whether inside or outside the network, is automatically trusted. Every access request is verified based on identity, context, and device health, significantly reducing the attack surface.

Data sovereignty is another critical factor, especially for organisations operating in regulated industries or across borders. It ensures that sensitive data is stored and processed within specific geographic or jurisdictional boundaries, aligning with national laws and privacy regulations.

Finally, a growing concern is that the public cloud infrastructure is predominantly owned by U.S.-based tech giants, such as AWS, Microsoft Azure, and Google Cloud. For enterprises operating in Europe and other regions, this raises valid questions about jurisdiction, government access, and long-term digital independence. As a result, many are exploring multi-cloud or hybrid models to retain greater control over where and how their data is hosted and governed.

Accelerated deployment and better application performance

With cloud modernisation, businesses can significantly speed up deployment times and improve application performance.

CI/CD pipelines and cloud-native tools enable faster development and testing cycles, ensuring faster time-to-market for new features and products. Cloud platforms also distribute workloads across multiple servers to ensure applications remain responsive under heavy usage.

Increased automation and reduced manual intervention

Cloud modernisation is closely tied to the automation of infrastructure management. With technologies such as Infrastructure-as-Code, businesses can automate routine tasks like provisioning, monitoring, and use fewer resources.

This reduces the need for manual intervention and minimises the likelihood of human error, enhancing operational consistency and reliability. Moreover, cloud platforms often include self-healing capabilities, where systems can detect and resolve issues automatically, further reducing downtime and improving operational efficiency. These automated processes free up IT teams to focus on more innovative tasks rather than mundane maintenance.

How to create cloud modernisation strategies?

Developing an effective cloud modernisation strategy requires a structured and iterative approach aligned with both business objectives and technical realities. Key components include:

Assessing the current IT landscape

The first step is a thorough assessment of your organisation’s existing IT environment. This means evaluating your existing systems, workloads, and cost structures to identify inefficiencies, technical debt, and any limitations imposed by legacy systems. Such an assessment helps pinpoint areas needing improvement and determines modernisation priorities.

Choosing the right approach and building governance

After understanding your current IT landscape, you can decide on the best cloud migration strategy for each application or service. The three main approaches are:

• Rehosting (Lift and Shift): moving applications to the cloud without making significant changes, typically for quick migration.
• Refactoring: making improvements or changes to the application’s code to better align with cloud capabilities while still retaining much of the existing structure.
• Rearchitecting: completely redesigning the application to fully leverage cloud-native features and scalability.

It’s also critical to build governance frameworks to establish policies around access, usage, and compliance to ensure the cloud environment is secure and aligned with industry standards.

Integrating automation and security from day one

Embedding automation and security into your cloud environment from the start is essential. DevOps practices, coupled with Infrastructure-as-Code, streamline deployment and scaling, improving efficiency. Security should also be integrated early through robust identity and access management systems, encryption, and automated compliance enforcement.

Optimising and continuously improving your cloud infrastructure

Cloud modernisation is a continuous process, not a one-time action. After migration, use cloud-native monitoring tools to track performance and health, iterating and optimising the environment as your business needs evolve. A continuous feedback loop ensures the cloud infrastructure remains agile and responsive.

What are the biggest challenges in cloud modernisation?

While the benefits are compelling, cloud modernisation also presents some challenges. Recognising and mitigating these risks early is key to a successful transformation:

Managing costs and preventing overruns

Unchecked cloud usage can result in inflated bills. Mitigate this by applying FinOps methodologies, setting clear budgets, and using real-time monitoring tools.

Ensuring security and compliance

A cloud-first model demands updated security strategies. Incorporate security by design, automate compliance enforcement, and utilise native cloud controls to remain compliant and secure.

Cloud migration and migrating legacy systems without disruption

Legacy applications often require careful handling. Minimise risk with a phased migration plan, hybrid approaches, and rigorous testing to maintain business continuity.

Choosing the right services and architecture

The abundance of cloud services can be overwhelming. Rely on cloud architects and vendor best practices to match workloads to the right services with an eye on flexibility and scalability.

Upskilling teams for the cloud

A modern cloud environment needs skilled professionals, while any resistance from the staff can slow down the pace of cloud adoption or create friction during the migration process. Invest in targeted training, certifications, and real-world experience to build a capable, cloud-ready workforce.

How long does a cloud modernisation project take?

The timeline for cloud modernisation depends on many factors, including workload complexity, migration strategy, business priorities, and cloud readiness. Some initiatives can be completed in a few months, while larger, enterprise-wide transformations may take over a year.

Projects that are guided by a clear roadmap, supported by executive sponsorship, and executed with agile methodologies tend to progress more smoothly. A phased approach with quick wins helps build momentum and stakeholder confidence.
