Enhancing Cloud Efficiency: The Role of Infrastructure as Code for NZ Orgs

In the face of cloud adoption challenges - expertise, integration, and operational efficiency - New Zealand organisations want better strategies to streamline their processes and accelerate the Solution Development Lifecycle (SDLC).

One approach that has emerged as a way to enhance efficiency is using Infrastructure as Code (IaC) automation. By embracing IaC, organisations can improve their SDLC execution speed and leverage modular solution blocks for faster and more reliable deployments.

Infrastructure as Code: A Game Changer for Cloud Efficiency

IaC is a practice that involves managing and provisioning computing infrastructure through machine-readable definition files rather than physical hardware or interactive configuration tools.

This automation allows you to rapidly set up cloud environments with consistent application deployment and an ability to scale infrastructure with less manual work.

IaC is modular, meaning organisations can build reusable blocks of infrastructure code, which can be easily deployed, updated, or replicated.

The Impact of IaC on the SDLC

Streamlining Architecture and Design

In the initial stages of the SDLC, which involves high-level architecture and conceptual design, IaC improves both precision and speed.

Your organisation can quickly iterate and validate concepts, moving from an "awful lot of ideas" to actionable infrastructure deployments in less time. This approach accelerates the architecture phase and ensures that the subsequent stages of the SDLC can be efficient.

Enhancing Cybersecurity Posture

With IaC, security controls can be embedded directly into the infrastructure code, ensuring that every deployment complies with security best practices and regulatory requirements. This 'security as code' approach streamlines the certification and accreditation process, enabling organisations to progress without compromising security.

Closing the Execution Gap

Perhaps the most significant impact of IaC is observed in the engineering phase of the SDLC, where the massive shortage of "doers" poses a critical bottleneck. IaC automates the provisioning and management of infrastructure, dramatically reducing the manual workload on engineers and site reliability engineers (SREs). This automation allows teams to focus on innovation and problem-solving rather than getting bogged down in repetitive setup and configuration tasks.

Reducing Cross-Phase Inefficiencies

By adopting IaC, organisations can avoid inefficiencies of slow development cycles and excessive hand-offs. Modular solution blocks can be designed, tested, and deployed with minimal dependency on inter-departmental transitions, supporting a more integrated and agile development process. The clear definitions and version control provided by IaC also enhance communication across teams, reducing the risks of miscommunication and errors during hand-offs.

Building Out the IaC Practice for Sustainable Success

To truly capitalise on the benefits of IaC, New Zealand organisations must invest in building out their IaC practice. You'll want to train teams in IaC principles and tools, establish best practices for code management, and foster a culture of continuous improvement and collaboration. As the practice matures, the modular solution blocks become more refined, further accelerating the SDLC and enhancing the organisation's ability to adapt to changing demands.


The journey to efficient cloud adoption in New Zealand is complex, but Infrastructure as Code emerges as a powerful lever to address the challenges of expertise, integration, and efficiency. By embracing IaC and building a robust practice, your organisation can transform its SDLC and achieve faster deployments, enhanced security, and greater scalability.

The strategic adoption of IaC will be pivotal in unlocking the full potential of cloud technologies.
