Turbo charging your Azure estate by modernising the applications that matter
This guest blog was written by Anthony Holland, Head of Presales: Cloud at ANS.
Many organisations have made solid progress with Microsoft Azure. Applications are running in the cloud, services are stable, and the estate appears to be working well.
In practice, however, progress can still feel frustratingly slow. Changes take longer than expected, initiatives lose momentum, and the platform does not always support what the business wants to do next. This is rarely about ambition. More often, it reflects an Azure environment that has been migrated but not modernised, where application design and operating models have not evolved alongside the cloud.
It is also important to recognise that not every application is suited to modernisation. Attempting to modernise everything at once rarely delivers value. Some workloads are constrained by legacy design, limited access to source code, or a weak business case. Focusing on the applications that matter most, and where modernisation is practical, helps ensure effort is directed where it will have the greatest impact.
The five signs below highlight when application modernisation becomes the natural next step, whether the goal is agility, resilience, security, or preparing the Azure estate for future innovation, including AI.
1. Changes take too long and feel risky
When even small updates take weeks to deploy or require extended change windows, applications are often the bottleneck.
Many Azure estates still rely on tightly coupled architectures or lift and shift virtual machines moved from on premise environments. These applications were never designed for frequent change, limiting automation, flexibility, and responsiveness.
Modern Azure architectures support modular applications, platform services, and automated delivery pipelines. This improves the speed of change while reducing deployment risk, allowing Azure to become an enabler rather than a constraint.
2. Resilience and security are hard to maintain
As environments grow, maintaining consistent security and resilience becomes more complex.
Legacy tooling, manual controls, and unsupported platforms make it harder to manage access, protect data, and respond to incidents. Application modernisation helps embed resilience and security into the platform itself using managed services, built in monitoring, and policy driven governance.
IDC research shows that organisations modernising applications on Azure reduced deployment times by up to 80% and cut unplanned downtime by 30 to 50%, directly strengthening resilience. This is essential not just for advanced scenarios like AI, but for keeping core services secure and reliable as the business evolves.
3. Cloud costs rise without clear business value
Azure offers flexibility and scale, but value is not always realised immediately. When applications are migrated without modernisation, inefficiencies such as over provisioning and manual operations often move with them. Over time, this makes it harder to link cloud spend to meaningful outcomes.
Application modernisation focuses on using Azure more effectively. By adopting PaaS services, automation, and right sizing, organisations can reduce waste while improving performance. Forrester research found that organisations modernising applications using Azure PaaS reduced application infrastructure costs by up to 40%.
FRISS followed this approach by working with ANS to modernise its Azure estate, improving scalability, efficiency, and the ability to support ongoing innovation.
4. Data is available, but hard to use
Azure provides access to more data than ever, but access alone does not create insight. When data is fragmented across systems, slow to retrieve, or dependent on manual reporting, its value is limited.
These constraints affect everyday decision making just as much as advanced analytics initiatives. Modern Azure data platforms address this by providing consistent, reliable access to high quality data across applications, supporting better reporting today while laying the groundwork for more advanced capabilities in the future.
Without a strong data foundation, much of the potential value of cloud and AI remains unrealised.
5. Teams spend more time maintaining systems than improving them
Azure can reduce operational effort, but only when applications are designed to take advantage of it. Where legacy architectures persist, teams often spend their time keeping systems running rather than improving them.
Application modernisation reduces this burden through automation, managed services, and standardised delivery. OneFamily took this approach alongside its move to Azure, working with ANS to improve scalability and resilience while creating a stronger foundation for future services, including AI driven capabilities.
When teams can focus on improvement rather than upkeep, innovation becomes sustainable.
From cloud adoption to cloud value
Application modernisation is not about rebuilding everything or chasing trends. It is about removing the constraints that limit value from Azure.
A modernised Azure estate enables faster and safer change, stronger security and resilience, clearer returns on cloud investment, and reliable data foundations. It also provides a platform that can support AI initiatives when and where they make sense.
As a Microsoft Azure Expert MSP, ANS supports organisations to modernise applications incrementally using proven approaches such as VM to PaaS re platforming, infrastructure as code, and platform optimisation.
If you want to unlock more value from Azure, whether that is speed, resilience, security, or readiness for future innovation, the first step is understanding where your estate is holding you back.
