GWRC's Cloud Transformation: Building a Modern Azure Ecosystem for Public Sector Innovation

Greater Wellington Regional Council (GWRC) is embarking on a transformative journey to modernize its IT infrastructure, turning to Microsoft Azure cloud enablement as the centerpiece of its strategy. The Council, which governs the greater Wellington region in New Zealand, has announced a tender for services that will not simply transition its existing workloads to Azure but will instead radically rethink how digital services are delivered across its organization.

Azure Enablement as a Strategic Imperative​

For many public sector organizations, the shift to cloud computing represents not just a technological upgrade but a strategic necessity. The GWRC’s approach stands out because it moves decisively away from “lift and shift” migrations that simply re-host legacy workloads on virtual machines. Rather, the Council is seeking a complete ‘greenfield’ build—designing, deploying, and operating an Azure environment from scratch that is purpose-built for current business needs while also being agile enough to meet future demands.
This vision is made clear in the language of the GWRC’s official tender, highlighted by the statement: “There is no appetite to simply ‘lift and shift’ existing applications or remediate the existing Azure environment. This would only transfer the current technical debt and legacy support requirements that the ICT strategy is attempting to eliminate.” Instead, GWRC aims for a structured, automated environment that minimizes technical debt, maximizes operational resilience, and equips staff with the skills required to operate complex cloud ecosystems.

From Legacy Systems to SaaS, Managed Services, and Containerization​

Historically, GWRC’s application portfolio has depended heavily on traditional virtualization, Windows operating systems, and on-premises deployments. While the organization already leverages both Microsoft Azure and AWS platforms, officials have stated they believe the current Azure setup is “not fit for purpose” when measured against strategic business goals.
Looking ahead, GWRC intends to fundamentally alter its service delivery model:

• Software as a Service (SaaS): Where possible, the Council will seek SaaS replacements for legacy applications, reducing maintenance overhead and benefiting from rapid vendor innovation.
• Managed Services: Applications that are not suitable for SaaS will be candidates for managed services, shifting operational responsibility to specialized providers.
• Containerized Applications: Cloud-native development will be a key focus, using containers and microservices architectures to build scalable, portable applications that integrate seamlessly with the broader Azure ecosystem.

This tri-pronged strategy echoes global enterprise trends, where IT leaders increasingly prefer consumption-based services to maintain focus on business value rather than infrastructure management. According to a Gartner report, by the end of 2025, over 85% of organizations adopting cloud will favor cloud-native architectures for new applications over monolithic, legacy designs—a projection strongly aligned with GWRC’s approach.

Automation at the Core​

One of the most notable aspects of the Council’s requirements is an explicit mandate for automation. The tender documentation specifies that automation is essential not only in the environment’s initial build but also for ongoing deployment and operational processes. Automation is expected to:

• Reduce manual, error-prone processes associated with traditional infrastructure management.
• Enable consistent repeatable deployments.
• Drive faster release cycles and enhance compliance through automated policy enforcement.

Automation in Azure typically centers around tools such as Azure Resource Manager (ARM) templates, Bicep, Azure DevOps, and Infrastructure-as-Code (IaC) paradigms. These enable organizations to codify cloud infrastructure, allowing instantaneous scaling and rollback, robust versioning, and comprehensive auditing. GWRC’s insistence on automation not only streamlines processes but also reduces long-term cost and risk related to human error—a lesson well-learned across sectors that have suffered outages due to misconfigurations.

‘Build, Operate, and Transfer’ Model: Upskilling for Self-Sufficiency​

GWRC’s chosen engagement model is best characterized as “Build, Operate, Transfer” (BOT). In this model, the selected service provider will:

• Build: Design and implement the new Azure environment from the ground up, adhering to best practices and organizational requirements.
• Operate: Initially manage day-to-day operations, ensuring the new environment is stable, secure, and fully functional.
• Transfer: Over time, transfer operational responsibility to the Council’s ICT team, providing comprehensive training and documentation along the way.

This approach has several notable strengths:

• Minimized Disruption: The initial operate phase ensures that the transition is smooth and that any operational kinks are ironed out under the watchful eye of an expert provider.
• Knowledge Transfer: By including a structured upskilling component, GWRC reduces long-term vendor dependency, empowering its staff to take full control of cloud operations.
• Future-Proofing: Staff trained on modern Azure paradigms will be better able to adapt and innovate as business needs evolve.

BOT engagements are common in complex digital transformations and align with the needs of public sector entities required to maintain in-house capability for compliance, security, and oversight reasons.

Critical Analysis: Strengths and Potential Risks​

Notable Strengths​

• Strategic Vision Over Tactical Fixes: By rejecting simple migrations in favor of a greenfield build, GWRC demonstrates a long-term focus. Moving straight to cloud-native architectures avoids inheriting legacy complexity and cost.
• Emphasis on Automation: This reduces operational risk and cost, while improving agility—a crucial factor for any organization undergoing digital transformation.
• Commitment to Staff Development: The inclusion of operational change and training in the tender requirements indicates a clear understanding that technology change alone won’t guarantee success.
• Platform Agnosticism: While Azure is the focus, GWRC’s prior experience with both Azure and AWS gives it flexibility. If executed well, this may allow future multi-cloud strategies—a growing need for regulatory and business resilience.
• Defined Operating Model: The BOT framework promotes stability during the transition away from legacy systems.

Potential Risks​

• Culture Change: Modern cloud environments require fundamentally different skills, working styles, and operational models than traditional virtualization. Even with strong training, there is a learning curve and possible resistance from staff.
• Vendor Lock-In: Deeply embedding into a specific cloud ecosystem, like Azure, could make future platform changes costly or complex, unless open standards and portability are prioritized. Containerization and open APIs may mitigate this risk but require vigilance in architecture decisions.
• Security and Compliance: While Azure offers robust security controls, successful implementation and operation depend on both technical configuration and staff awareness. The rapid shift to cloud and SaaS models may expose GWRC to new regulatory or data residency challenges.
• Cost Management: Although cloud architectures are promoted for their cost efficiency, especially when compared to on-premises deployments, organizations can find themselves exposed to new types of costs and budgeting uncertainties if resource usage is not carefully monitored and automated.
• Transition Risk: The initial build and operate phases must be tightly managed to avoid outages, misconfigurations, or service interruptions that could impact core council operations.

Lessons for Broader Public Sector IT​

The GWRC story offers valuable lessons for other public sector organizations:

• Consider cloud migration as an opportunity for reinvention, not just cost-cutting. Treating cloud as an endpoint rather than a tool can undermine potential value.
• Adopt automation from the outset to ensure scalability, agility, and compliance. Automation is not just a luxury but a fundamental enabler of cloud success.
• Prioritize operational change management. Technology by itself is not transformative. People, process, and culture need to evolve in parallel.
• Demand transparency and knowledge transfer from partners to avoid lock-in and build in-house capability. Ensure all critical documentation and training are delivered, and conduct regular knowledge validation as part of project milestones.

Key Technical Considerations for Successful Azure Enablement​

To deliver on its bold strategy, GWRC’s future partner will need to address an array of technical concerns:

• Network and Identity: Implementing secure, scalable networking within Azure, with robust identity management and integration with on-premises directories via Azure AD Connect.
• Data Migration: Planning data movement from existing systems to Azure while ensuring continuity and minimal downtime.
• Application Modernization: Re-architecting legacy apps for SaaS or containers, retiring or refactoring those no longer fit for purpose.
• Security Posture: Applying Azure-native security controls—role-based access, encryption, advanced threat protection, and compliance tooling.
• Automation Pipeline: Codifying infrastructure with ARM/Bicep or Terraform, automating deployments, monitoring, and patching.
• Governance: Defining policies around cost management, resource tagging, automated policy enforcement, and audit logging using services like Azure Policy and Azure Monitor.
• Resilience: Building in high-availability architecture, geo-redundancy, and disaster recovery strategies.
• Documentation and Handover: Delivering detailed runbooks, configuration guides, and operational documentation to support the “transfer” stage of the engagement.

Each of these elements is critical to building a cloud environment that is robust, manageable, and aligned with public sector compliance mandates.

The Broader Context: Public Sector Cloud Adoption in New Zealand and Beyond​

GWRC’s cloud enablement initiative is emblematic of a larger trend sweeping New Zealand’s public sector. Agencies across government are gradually decoupling from on-premises data centers, seeking the flexibility and innovation that comes with adopting best-of-breed cloud platforms. According to the New Zealand Government’s “Cloud First” policy, agencies are encouraged to adopt cloud computing where it delivers value, provided that risks can be effectively managed.
This policy shift has been accompanied by updated guidance around procurement, vendor management, and risks relating to sovereignty, privacy, and procurement transparency. GWRC’s procurement process—which specifies a structured tender, strict evaluation criteria, and requirements for skills transfer—reflects growing public sector sophistication in managing these transformations.
Internationally, GWRC’s model draws lessons from similar initiatives, like the UK’s Government Digital Service (GDS) model or the Australian Digital Transformation Agency’s cloud frameworks, which emphasize not only technology adoption but also operating model change and transformation governance.

What to Watch: The Road Ahead for GWRC​

The outcome of GWRC’s Azure enablement project will be closely watched—not just within New Zealand, but by public sector and enterprise IT leaders worldwide. If successful, it could establish a model for how government agencies can adopt cloud while maintaining operational control, transparency, and resilience.
Key milestones will include:

• Selection of an Azure enablement provider: The open tender closes on July 18, and the choice of provider will shape both the technical strategy and cultural approach adopted.
• Infrastructure build and initial transition: How rapidly and robustly the new environment can be stood up, and how effectively automation is embedded from day one.
• Staff training and handover: The quality and completeness of internal knowledge transfer will be a critical success factor.
• Measurable business benefits: GWRC will need to demonstrate that its investments result in more agile, reliable, and cost-effective digital services. Metrics to watch include reduction in unplanned downtime, faster service deployment, user satisfaction, and total cost of ownership compared to legacy systems.
• Ongoing adaptability: The cloud landscape is continuously evolving. GWRC must ensure that its new environment is not only secure and cost-effective now, but also remains flexible as business needs and technology paradigms shift.

Conclusion​

The Greater Wellington Regional Council’s bold approach to Azure enablement is more than a simple IT upgrade: it’s a comprehensive strategy to transform how public services are delivered in the cloud era. By rejecting incrementalism in favor of a clean-slate build, placing automation and training at the core, and focusing relentlessly on future-readiness, GWRC offers a template that other government agencies—and indeed, enterprises—can learn from.
While risks around cultural change, vendor dependency, and technical delivery must be carefully managed, the benefits of a properly executed greenfield cloud build are significant: greater agility, lower long-term cost, improved compliance, and a far more empowered workforce. As the procurement enters its next phase, stakeholders across the sector should pay close attention. What unfolds in Wellington could shape best practices for public sector cloud adoption far beyond New Zealand's borders.
