DevOps and Cloud Maturity Models provide frameworks to understand an organization's current state, plan for improvements, and systematically reach higher levels of efficiency and agility.

This blog introduces traditional DevOps Maturity Models, along with Cloud Maturity Models, and touches on how providers like AWS and Azure offer guidance tailored to their ecosystems.

What is DevOps?

DevOps combines cultural philosophies, practices, and tools to increase an organization’s ability to deliver applications at high velocity, facilitating faster and more frequent software releases. The aim is to break down silos between development and operations, enhancing collaboration and continuous improvement. A mature DevOps implementation leads to faster time-to-market, improved collaboration, better reliability, and a more agile organization.

However, DevOps isn't a binary concept; it's a journey requiring incremental changes in culture, processes, and tools across an organization. The DevOps Maturity Model can help guide this transformation.

Understanding the DevOps Maturity Model

The DevOps Maturity Model outlines stages that an organization goes through as it integrates DevOps practices. These stages represent milestones in maturity and efficiency, progressing from initial manual workflows to full automation, agile collaboration, and continuous improvement. In this blog, we’ll explore each level in depth, highlighting key practices and goals in core areas like automation, testing, security, and monitoring.

Level 1: Initial

In the Initial stage, organizations are early in their DevOps journey with few processes automated, limited collaboration, and mostly manual workflows.

• Organization & Culture: DevOps practices are unfamiliar, with long up-front planning phases and rigid team structures. Teams work in silos, leading to slow, sequential development and delivery.
• Build & Delivery: Teams may follow a Waterfall approach, with a focus on feature completion over business outcomes. Code is not yet centralized, with workflows often fragmented and reactive.
• Automation: Infrastructure is manually provisioned, prone to errors, and time-consuming. Servers are managed individually, with ad-hoc updates.
• Testing: QA is predominantly manual and happens late in the process, creating bottlenecks and reducing feedback speed.
• Security: Security is last-minute, focusing on the minimum security scans needed to meet compliance.
• Monitoring: Few monitoring systems are in place. Issues are often detected by users, making recovery times lengthy and difficult.

Level 2: Managed

At the Managed stage, teams begin applying DevOps practices, often on isolated projects, with increased automation and collaboration.

• Organization & Culture: Small teams experiment with DevOps, piloting agile practices and cross-functional collaboration. Dev and Ops work together on specific projects, laying a foundation for broader cultural changes.
• Build & Delivery: Basic version control is adopted. Developers work in feature branches, promoting incremental improvements and version control consistency.
• Automation: Automated deployments are introduced, reducing errors in releases. Infrastructure setup and provisioning remain largely manual, but deployment to environments is faster.
• Testing: Testing shifts left, with unit and integration tests added earlier in the process. Automated testing tools start reducing manual QA reliance.
• Security: Security practices are still distinct but begin to integrate into project planning, with some early assessments.
• Monitoring: External monitoring for user-facing systems informs teams of performance or availability issues.

Level 3: Defined

At the Defined stage, DevOps practices are standardized across projects, improving efficiency and creating a stable foundation for more sophisticated automation.

• Organization & Culture: Consistency is achieved across teams, with established standards and collaboration workflows. Teams are aligned with business goals and organized around products or projects rather than skills.
• Build & Delivery: Agile methodologies gain traction, enhancing cross-departmental alignment and transparency. Continuous integration is introduced, making builds more frequent and predictable.
• Automation: Automated provisioning begins, reducing infrastructure setup time and enabling teams to deploy more reliably.
• Testing: Comprehensive testing, including security scans, is integrated into the pipeline, improving quality at every stage.
• Security: Security experts consult on architecture and testing, implementing “Shift Left” security with scans and assessments earlier in development.
• Monitoring: Basic external site monitoring alerts the team of risks and interruptions as soon as they impact the user.

Level 4: Measured

In the Measured stage, automation becomes a core practice, with self-service capabilities and detailed monitoring to optimize performance and minimize risk.

• Organization & Culture: Teams work independently yet collaborate effectively, leveraging shared knowledge. Mentorship fosters a culture of learning, encouraging best practices.
• Build & Delivery: Agile practices evolve into Lean methodologies, emphasizing continuous improvement. Changes are frequent and predictable, with reduced cycle times.
• Automation: Infrastructure becomes fully automated, relying on immutable infrastructure patterns. Environments are provisioned as needed, allowing developers to focus on innovation.
• Testing: Automated performance testing validates code readiness for production at scale.
• Security: Continuous monitoring detects vulnerabilities in dependencies and ensures secure code practices.
• Monitoring: Monitoring covers the entire application lifecycle, capturing metrics that inform real-time and retrospective analysis.

Level 5: Optimised

At the Optimised stage, DevOps becomes second nature, with highly automated, scalable, and adaptive systems that enhance agility and business alignment.

• Organization & Culture: The organization is structured for agility, with interdisciplinary teams that rotate through support roles, ensuring operational knowledge and empathy for end users.
• Build & Delivery: CI/CD is deeply integrated, enabling deployments without manual intervention. Teams innovate rapidly, pushing new ideas to production in hours or days.
• Automation: Fully automated pipelines move code from development to production seamlessly, supporting experimentation and scaling.
• Testing: Real-world scenario testing predicts product behavior post-deployment, with comprehensive performance insights.
• Security: Security is a shared responsibility. Every team integrates security best practices, ensuring that it’s embedded at every layer.
• Monitoring: Advanced observability supports quick diagnostics, analysis, and optimizations, enabling proactive issue resolution and customer satisfaction.

Each level highlights a transformative stage in the DevOps journey, guiding organizations from siloed, manual processes to a holistic, automated, and agile DevOps culture.

Cloud Maturity Model: Navigating the Cloud Transformation

Cloud maturity models are essential frameworks that help organizations assess and enhance their cloud capabilities, focusing on areas like adoption, security, and cloud-native development. By evaluating cloud maturity, organizations can align their technological advancements with business objectives, leveraging cloud technology more effectively at each stage of development.

Cloud Adoption Maturity Model

The Cloud Adoption Maturity Model measures an organization’s progress in adopting cloud infrastructure, focusing on their technical knowledge, cloud-readiness, and cultural adaptability. Each level represents a sequential stage in cloud evolution, requiring organizations to fully establish each phase before advancing to the next:

• Legacy: The organization’s journey begins here, with no existing cloud-ready applications, infrastructure, or services.
• Ad Hoc: Organizations begin with basic cloud technologies, typically leveraging Infrastructure as a Service (IaaS) for resources like compute, storage, and networking on a pay-as-you-go basis.
• Repeatable: Processes for cloud migration become consistent, and initiatives like a Cloud Center of Excellence (CCoE) are established to support scalable cloud adoption.
• Optimized: Cloud resources are used efficiently, with standardized foundations supporting all new cloud initiatives.
• Cloud-Advanced: The organization operates predominantly in the cloud, with optimized processes that are seamlessly integrated into business operations.

Cloud Security Maturity Model

As organizations transition to the cloud, Cloud Security Maturity becomes crucial. Cloud security relies on both the cloud service provider’s (CSP’s) controls and the client’s configuration. The Cloud Security Alliance’s model provides a framework to enhance security at each maturity level, though not all organizations need to adopt every component:

• No Automation: Security practices are fully manual, with teams relying on dashboards to identify and respond to issues.
• Simple SecOps: Initial automation appears, with some Infrastructure as Code (IaC) deployments and federated accounts.
• Manually Executed Scripts: Automation grows, often involving multi-factor authentication (MFA) and increased account federation, though most actions remain manual.
• Guardrails: Automation expands across accounts, implementing guardrails as governance policies.
• Automation Everywhere: Security becomes fully integrated through IaC, with extensive MFA and federation, automating most security operations.

Cloud-Native Maturity Model

The Cloud-Native Maturity Model (CNMM) focuses on an organization’s capability to build and manage cloud-native applications, often leveraging open-source tools. This model highlights the importance of cloud-native development for agility and scalability, with organizations moving from basic cloud understanding to complete self-sufficiency:

• Build: Limited organizational support exists for early cloud-native projects, often limited to proof of concept (POC) applications.
• Operate: Cloud-native skills are developing, with DevOps teams forming and agile practices emerging. SMEs (Subject Matter Experts) begin to establish themselves within the organization.
• Scale: Cloud-native approaches are now standard, with heightened stakeholder support. Training in security practices is broad, and the organization centralizes responsibilities for efficiency.
• Improve: Cloud is the default infrastructure. Optimization and process improvement become central focuses as the organization adopts Kubernetes for container orchestration.
• Optimize: The organization is fully cloud-native, with distributed service ownership and a mature DevSecOps culture, enabling scalable operations, effective experimentation, and FinOps practices.
