Let’s assume, at a larger manufacturing site, one wants to collect and analyze data of 1000 sensors (1 data set per second with 10kB raw data) over a correlation time window of 1 month. Then one must deal with data speed and volume together defining the raw cloud ingress bandwidth for time series only, requiring:
- Cloud uplink network bandwidth = 1000 x 8x10kB x 1/s = 80 Mbit/s
- Data volume to compute/ day = 80 Mbit/s /8 x 3600 x 24 = 864 GB/day
- 30-day storage capacity = 864 GB/day x 30 = 26 TB/month
The required uplink bandwidth could be a limiting factor for public cloud-based deployments (lack of network bandwidth or telco cost). IoT workloads have a 24/7 nature, so the IoT solution must be available as well on a 24/7 basis, which stresses the service management team and impacts cost. Hence a combination of a private cloud with a turnkey IoT solution continues to be a big desire across many industry verticals.
Furthermore, multiple industries require local private cloud solutions to meet regulatory requirements, such as what is typically found in Utilities, Government, and Defense verticals. Besides the technical hurdles, one also must cope with specific regulations and security to incorporate and certify. E.g. in the US regulatory compliance with ITAR or FEDRAMP is easier to achieve, or do not apply like FEDRAMP for full on-premise private cloud.
Through the advent of industrial IoT in the industry, manufacturers can now make use of commercially provided industrial IoT solutions. Siemens’ MindSphere is the leading industrial IoT as service solution that collects and analyzes real-time sensor data from products, plants, systems, and machines, enabling users to optimize products, production assets, and manufacturing processes along the entire value chain to build a real-time digital twin.
Siemens invests in industrial IoT and offers MindSphere to help customers on their journey. The Siemens customer experience shows that using pre-built IoT solutions has advantages compared to a build-your-own IoT solution from scratch:
- 60% shorter time to value
- 25% less OPEX
- 40% less CAPEX
- 90% risk reduction in the overall project
