Unless access to the Internet is essential to operations.
Backup power can get a router up and going again, but it does nothing to support the infrastructure of access points that connect a business to the Internet.
Planned power outages highlight a major architectural and design issue every IoT designer needs to consider: What happens if there’s power but no Internet?
Smart applications like factories, buildings, and cities use the cloud for several reasons, including data storage and data analytics.
If the programs to run an industrial machine are kept in the cloud, the machine will be unable to access its programs and unable to run.
During an outage a generator can power a machine, but the machine still can’t be used unless there is a redundant (i.e., local) copy of its programs and a mechanism for getting them to the machine.
In this case, Internet access represents a single point of failure.
It’s not that IoT systems need a redundant Internet.
Rather, they need an alternative way to do what Internet access enables.
Put another way, you need to provide a local method for doing what’s being done in the cloud.
In many cases, the cloud provides additional capabilities like optimizing workloads, analyzing sensor data, or enabling predictive maintenance.
Mission-critical capabilities, such as program storage, will need local redundancy (i.e., backup capabilities).
Because programs are loaded irregularly, a single computer might be able to provide a temporary fix that, while not the most efficient or convenient approach, still keeps the business operational (i.e., reduced capabilities).
Some cloud functions collect data and analyze it.
This data is not run-time essential and lack of access should not shut down the machine.
Many times the cloud is used to collect data.
Redundancy in the Internet of Things is also a serious consideration for autonomous vehicles that require cloud access to operate
