New Azure Landing Zone lays foundation for legal giant’s cloud innovation

When one of the UK’s leading law firms faced a data centre closure, we migrated their infrastructure and applications to Azure. Our approach didn’t only avoid significant capital expenditure. With a scalable Azure Landing Zone, improved DevOps practices, centralised Innovation Hub, as well as CI/CD and Infrastructure as Code (IaC) for governance and control, the enterprise has achieved multiple financial savings, enhanced customer satisfaction, and laid the foundation for future growth and innovation.

Objectives summary

  • Implement an optimised delivery system to enhance the Azure platform and support application workloads.
  • Establish an innovation hub to drive centralised collaboration, for faster innovation and the automation of Azure Landing Zone improvements.
  • Improve the security posture through cloud security initiatives.
  • Improve visibility across the estate using best-in-class monitoring technology.
  • Optimise costs by reducing cloud waste through automated VM power cycling, reduced Azure consumption, the removal of idle resources, and more cost-effective pricing options across the cloud estate.

At-a-glance metrics:

  • 25% reduced Azure consumption
  • 30% improved security score
  • 50% faster engineer onboarding
  • 40% faster delivery velocity
  • >£1m cost savings per annum
  • 2,160 training hours saved per year

The brief

A detailed understanding of the organisation’s current state, and close collaboration to align any proposed activity with the client’s business objectives, uncovered the following strategic opportunities:

  • Rapid transition: Leverage an accelerated migration strategy to exit a legacy data center, align with strategic financial objectives and streamline capital expenditure.
  • Strengthen security: Address several targeted security enhancements to significantly improve the firm’s security score and overall posture.
  • Enhanced technical leadership: Reinforce technical leadership and expand engineering capacity within the team, to accelerate modernisation efforts and improve project delivery.
  • Improve visibility and monitoring: Achieve full transparency across the cloud estate, to enable proactive management of workload stability, scaling and recovery.  
  • FinOps Cost Control: Implement robust cost management strategies, to enhance financial oversight and optimise expenditure through FinOps practices.
  • Complex Infrastructure as Code (IaC): Remedy the complexity of the existing Azure Landing Zone. Written in Bicep, the codebase had grown organically and become unnecessarily convoluted, slowing new engineers’ time to value. Poor documentation and a lack of standardisation further slowed ongoing development.

The solution

1. DevOps Accelerator

A DevOps Accelerator was designed to streamline development and operational processes by introducing automated CI/CD pipelines. This allowed the client to reduce time to market for internal and client-facing applications. Technical leadership was also unified under a new DevOps vision, eliminating silos and driving collaboration across departments. Stakeholder engagement was significantly improved, leading to higher satisfaction and project success.

2. Delivery System Designer

A Delivery System Designer optimised the visibility and management of fulfilment, ensuring the cloud platform team could focus on resource allocation and capacity planning, to prioritise demand and drive customer satisfaction. Delivery velocity increased by 40% without any additional resource requirements.  

3. Azure Landing Zone (ALZ) improvements

Improvements made to the Azure Landing Zone – including automated provisioning – have enabled the client to safely migrate workloads to the cloud while ensuring data integrity and compliance. The benefits are increased security and governance for regulatory compliance, as well as the scalability to support future workloads.

4. Innovation Hub

A centralised Innovation Hub was created to drive continuous improvement. This environment allows for experimentation with new technologies, enabling the client to respond quickly to market demands and technological advancements. Connecting technical SMEs with leadership, it also drives greater collaboration for better alignment between technical teams and business stakeholders.

5. Cost optimisation initiatives

VM power cycling led to a 25% reduction in Azure consumption, and improved visibility will strengthen ongoing financial governance too. By automating resource management and leveraging Microsoft’s pricing initiatives, we achieved in excess of £1m cost savings YoY.

 

6. Cloud security innovations

We implemented cloud security initiatives including vulnerability assessments, threat detection, and industry-leading continuous monitoring, to enhance the organisation’s security posture. These improvements – which align with CIS and NIST frameworks – resulted in 30% security score progress, which reduced the firm’s vulnerabilities while improving compliance.

7. Automated Self-Service Integration

A seamless integration was built between the firm’s ITSM and Azure DevOps release pipelines, enabling fully automated, end-to-end fulfilment. As a result, the streamlined system with approval workflows, provides the capability to reduce VM build times from 5-10 days to just a few unattended hours.  This self-service approach – with minimal reliance on engineers and architects – typically increases productivity by 50-70%, with even greater potential ROI gains as the solution scales.  

Conclusion

This legal firm has not only achieved an accelerated cloud migration, security innovations, and an optimised delivery system. With a robust foundation for future growth and innovation, attention has now moved to the next phases of the project, with identity migration, app modernisation, and FinOps improvements set to further optimise their cloud environment and maximise the ongoing value of their cloud investments.

"Digital transformation projects such as this can easily achieve an ROI in under 12 months. But the business case shouldn’t only focus on avoiding capital expenditure – we’ve unshackled the capacity and capabilities of valuable talent, designed an environment that truly nurtures onward innovation without jeopardising security, and strengthened the organisation’s ability to satisfy and react to changing customer demands. Seven-figure cost savings certainly do quantify the impact of our work though!”
