When it comes to critical industrial workloads, the decision of whether to keep them on-site at the enterprise edge or transfer them to distant cloud data centers is not a straightforward one. The realm of Industry 4.0 presents unique challenges in designing and implementing digital infrastructure for critical industries. No single approach fits all scenarios, and the absence of rigid rules further complicates matters. However, despite claims to the contrary, there are indeed rules-of-thumb that provide guidance in this complex landscape. Latency, bandwidth, privacy, and security emerge as key factors influencing the placement of data processing, according to insights from Siemens and other industry experts. While privacy and security are closely intertwined, they represent distinct considerations. The former emphasizes adherence to local data processing regulations, while the latter focuses on safeguarding against cyber threats and data breaches. These factors collectively drive the need for edge computing solutions. The consensus among industry professionals is that application performance, determinedlatency and bandwidth, often dictates the need for edge computing. Additionally, concerns about security, privacy, and a general wariness of public infrastructure contribute to the preference for edge deployments. Reliability, a critical aspect of infrastructure uptime, is another aspect that informs the decision-making […]
