The rapid evolution of cloud computing has ushered in a new era allowing businesses to scale efficiently, reduce operational costs, and tap into a vast ecosystem of services and tools. One of the pivotal decisions you may face while embracing cloud infrastructure, especially on platforms like Microsoft Azure, revolves around your migration strategy. A common method, known as lift-and-shift involves directly moving existing applications and data to the cloud without major modification. However, while this approach offers speed and simplicity, it often does not exploit the full potential and innovations offered by migrating to Microsoft Azure.


1 – Embrace optimisation opportunities

Lift-and-shift largely preserves the legacy structure of applications. This means that any inefficiencies, bottlenecks or quirks that existed in the on-premises architecture will persist into the cloud, forfeiting the opportunity for optimisation. Transitioning to Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) solutions allows you to re-architect and refine your processes, taking full advantage of the cloud’s scalability and flexibility.

Cost Consolidation

2 – Cost consolidation

While it might seem cost-effective initially, the lift-and-shift approach can lead to higher operational expenses in the long run. Virtual Machines (VMs) in the cloud still require patching, maintenance, and licensing. Conversely, leveraging PaaS and SaaS models can translate to significant cost savings as many of the underlying infrastructure management tasks are taken away, and you only pay for the services you consume.

Innovative Features

3 – Innovative features

Cloud providers, especially platforms like Azure, are continuously innovating. There are numerous managed services, from databases to AI and analytics, designed specifically for cloud-native architectures. By adhering strictly to a lift-and-shift model, you won’t be able to use these advanced features, impeding your growth and competitive edge.

4 – Security and compliance

While cloud providers invest heavily in securing their infrastructure, a direct lift-and-shift could leave potential vulnerabilities that existed in the on-premises setup. Transitioning to PaaS and SaaS solutions can strengthen security postures as these services come with built-in security features and are regularly updated to address the latest threats.


5 – Scalability and performance

One of the most lauded benefits of the cloud is scalability. However, lift-and-shift migrations might not be inherently designed to scale horizontally or to be distributed. By moving to PaaS or SaaS, applications can be designed or chosen based on their inherent ability to scale with demand.

Future Proofing

6 – Future-proofing

The technological landscape is ever-evolving. A lift-and-shift approach might make future migrations or upgrades more complex and cumbersome. In contrast, by adopting PaaS and SaaS solutions, businesses ensure they remain agile, able to adapt to future technological shifts with minimal friction.

While lift-and-shift migrations offer a quick way to move to the cloud, they might not be the best long-term strategy for businesses keen on harnessing the full power of the cloud. By migrating to Microsoft Azure using a transformational strategy that embraces PaaS and SaaS solutions, you can optimise your costs, tap into innovative features, and bolster security. Ensuring you are well-positioned to adapt to future technological advancements.
