IT/OT integration plays a central role in the fourth industrial revolution (Industry 4.0). Two approaches are common for smart factories and connected operations: Infrastructure as Code (IaC) and No/Low Code platforms. In this article, we compare Infrastructure as Code vs No/Low Code platforms. The article compares advantages and disadvantages and highlights how i-flow combines the best of both worlds. 
What is Infrastructure as Code (IaC)?
Infrastructure as Code (IaC) in the context of Industrial IoT refers to the automated management and provision of services for the integration of OT and IT using machine-readable configuration files.
Advantages and disadvantages of Infrastructure as Code (IaC)
Infrastructure as Code (IaC) offers the following advantages and disadvantages.
Pros:
-
- Scalability: IaC is ideal for large environments and enables consistent deployment across multiple systems.
- Customization: IaC offers a high degree of flexibility. This enables teams to configure and adapt the infrastructure down to the smallest detail – ideal for complex industrial requirements.
- Automation version control: IaC minimizes manual errors with automation tools and integrated version control. Version control also enables changes to be tracked over time.
Cons:
- Steep learning curve: Mastering IaC requires knowledge of both programming and infrastructure management, which makes it a challenge for non-developers.
- High initial costs: Proof-of-concepts (POCs) and the initial rollout can be costly and time-consuming, with ROI often only being achieved with large-scale implementations.
- Resource-intensive: The need for qualified DevOps experts leads to higher personnel and operating costs.
- Complex troubleshooting: Troubleshooting IaC configurations can be time-consuming and complex, especially in multi-layered environments.
What is Infrastructure as No/Low Code?
Infrastructure as No/Low Code in the context of Industrial IoT refers to the automated management and provision of services for the integration of OT and IT that requires no or minimal programming skills. Instead of writing machine-readable configuration files, users use visual interfaces or simple workflows to define and manage the infrastructure.
Advantages and disadvantages of no/low code platforms
Infrastructure as No/Low Code offers the following advantages and disadvantages.
Pros:
-
- Faster time-to-value/ROI: No/low-code platforms are designed for rapid deployment, resulting in faster ROI and time-to-market.
- User-friendly interface: These platforms allow non-developers to manage system configurations and workflows, significantly reducing reliance on specialized IT staff.
- Cost-efficient: Lower personnel and infrastructure costs make no/low-code solutions ideal for small to medium-sized enterprises (SMEs) and companies with limited resources.
- Rapid prototyping: No/low code platforms support rapid iterations and enable teams to test, refine and implement solutions quickly.
- Simplified maintenance: The administration and updating of systems is simplified by easy-to-use interfaces.
- Seamless integration: Pre-built connectors simplify the integration of different IT and OT systems and improve operational efficiency and connectivity.
Cons:
- Limited customizability: Ease of use comes at the expense of flexibility and often limits the ability to meet highly specialized requirements.
- Scalability: No/low-code platforms can be disadvantageous compared to IaC in the case of very complex and extreme scaling requirements (e.g. millions of systems).
i-flow – the perfect combination of both worlds
i-flow offers a software solution for OT/IT integration that combines the flexibility of IaC with the ease of use of no/low code. The solution is designed to ensure both fast time-to-value and efficient rollouts. The most important features of i-flow:
- Rapid development and scalability: i-flow is designed for rapid scaling. Whether you want to deploy a single integration or manage complex pipelines across multiple systems, the built-in workflows enable rapid scaling from 1 to n integrations. This allows companies to expand their infrastructure at a pace that matches their growing needs.
- Intuitive interface with customization options: i-flow offers an intuitive, user-friendly interface for quick setup, but also customizable toolkits and SDKs for developers who need advanced customization. This ensures flexibility without sacrificing simplicity.
- Integrated version control: i-flow integrates version control to track changes to the infrastructure so that teams can efficiently monitor, manage and undo changes. This feature mirrors the version control capabilities of traditional IaC systems, but is accessible through a streamlined process.
- API for CI/CD integration: i-flow includes an API for seamless CI/CD pipeline integration, enabling automated deployments and updates as part of continuous integration and deployment processes. This ensures that organizations can maintain fast, reliable and scalable infrastructure management.
