Building software for mission-critical embedded systems is becoming increasingly complex. There is demand for more intelligence at the edge and a path toward software-defined autonomous systems. Requirements and mandates for safety and security compliance are increasingly time-consuming, resource intensive, and expensive. Accelerating innovation while also leveraging and supporting legacy assets, systems, and applications can be staggeringly difficult. The secret to overcoming the ever-increasing complexity of embedded software development lies in leveraging advancements in agile software development. In addition to agile approaches such as CI/CD, modern software frameworks, and cloud-native deployment, strategies including virtualization and container technologies are driving improvements in efficiency and productivity. Thoughtful application of these technologies enables DevSecOps teams and embedded software developers to accelerate innovation and delivery while also maximizing the ROI on current projects or processes.
