Containers vs. SCADA

What's the Difference?

Containers and SCADA are both technologies used in the field of software development and industrial automation, but they serve different purposes. Containers are used to package and deploy applications in a lightweight and portable manner, allowing for easy scalability and efficient resource utilization. On the other hand, SCADA (Supervisory Control and Data Acquisition) systems are used to monitor and control industrial processes in real-time, providing operators with valuable insights and enabling them to make informed decisions. While containers focus on application deployment and management, SCADA systems focus on process control and data acquisition in industrial settings.

Further Detail


Containers and SCADA (Supervisory Control and Data Acquisition) systems are both widely used in the field of technology and automation. While they serve different purposes, they share some similarities in terms of their attributes and functionalities. In this article, we will compare the key attributes of containers and SCADA systems to understand their differences and similarities.


Containers are a form of lightweight, portable, and self-sufficient software packages that contain everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings. They are isolated from each other and from the underlying host system, making them easy to deploy and manage. On the other hand, SCADA systems are used to monitor and control industrial processes, such as manufacturing, production, and infrastructure. They collect data from sensors and instruments in real-time and provide operators with a graphical interface to monitor and control the processes.


Containers are typically deployed using container orchestration tools like Kubernetes, Docker Swarm, or Apache Mesos. These tools help manage the deployment, scaling, and monitoring of containers across a cluster of machines. Containers can be easily deployed on any infrastructure, whether it's on-premises, in the cloud, or in a hybrid environment. SCADA systems, on the other hand, are usually deployed on dedicated hardware or servers within an industrial environment. They require specialized software and hardware to communicate with sensors and control devices.


Containers offer a high level of flexibility and portability, allowing developers to package their applications once and run them anywhere. They can be easily moved between different environments without any changes to the underlying code. This makes containers ideal for microservices architectures and continuous integration/continuous deployment (CI/CD) pipelines. SCADA systems, on the other hand, are designed for specific industrial processes and are less flexible in terms of deployment and customization. They are often tailored to the needs of a particular industry or organization.


Containers provide a level of isolation from the underlying host system, which helps improve security by limiting the impact of any potential vulnerabilities. However, containers share the same kernel as the host system, which can pose security risks if not properly configured. SCADA systems, on the other hand, are often deployed in critical infrastructure environments where security is a top priority. They use specialized protocols and encryption techniques to secure communication between devices and the SCADA system.


Containers are highly scalable and can be easily scaled up or down based on demand. Container orchestration tools like Kubernetes allow for automatic scaling of containers based on resource usage or other metrics. This makes containers ideal for applications that need to handle varying workloads. SCADA systems, on the other hand, are typically designed for a specific industrial process and may not be as easily scalable. Adding more sensors or control devices to a SCADA system may require additional hardware and configuration.

Monitoring and Management

Containers can be monitored and managed using tools like Prometheus, Grafana, or Kubernetes Dashboard. These tools provide insights into the performance and health of containers, as well as the ability to manage and troubleshoot issues. SCADA systems, on the other hand, come with built-in monitoring and management capabilities that are tailored to industrial processes. They provide real-time data visualization, alarms, and notifications to operators to help them make informed decisions.


In conclusion, containers and SCADA systems have different attributes and functionalities that make them suitable for different use cases. Containers offer flexibility, portability, and scalability for modern applications, while SCADA systems provide monitoring and control capabilities for industrial processes. Understanding the differences between containers and SCADA systems can help organizations choose the right technology for their specific needs.
