How can IoT cloud services be made more reliable without excessive cost?
...double the costs for a provider, making it technically infeasible.
Doubling costs isn't really "technically infeasible", it justs make the situation more expensive. However, it's not really that ...

Which problems with cloud computing make edge computing useful?
Remember, you are always processing data at the edge, even if it's not obvious. The choice to sample data at a particular frequency, whether that is 1Hz or 100Khz (particularly with analogue data), is ...

Why might data be sent to a cloud service when it could be processed on the edge?
There are many factors in choosing whether to process data on-device or in the cloud.
Benefits of processing in the cloud
If the algorithm uses floating-point or runs on a GPU, it might not be ...

How can IoT cloud services be made more reliable without excessive cost?
Most importantly you'd need a reliable load balancing infrastructure. That's where the real problem is situated. The services that provide load balancing and indexing where the other stuff is. Having ...

How rapidly should the data from IoT devices be sent to the cloud?
Sending packets at a high rate 'feels' wrong, and does increase the chances of seeing some odd effects when the network latency spikes occasionally. In this instance, the fact that you're in a ...

How rapidly should the data from IoT devices be sent to the cloud?
I think the best way is to have a different interval for sending data over the air, and a different (preferably settable) time interval for logging the data into your data repository. How this helps?

How can IoT cloud services be made more reliable without excessive cost?
One idea might be to use multiple Function as a Service providers (e.g. AWS Lambda, Azure Functions or Google Cloud Functions) so that if one fails, the other services can be used instead.

Is there an equivalent to the rsync toolset/protocol for the IoT world
It is possible with rsync but it is 1-1 and needs you to have a server running in the cloud. If you use Amazon S3 instead, you can just use the AWS client with the sync option to put the data to S3 in ...

compute power for MQTT vs HTTP POST in cloud
An idle connection will use very, very little power. Just need to handle a few keep alive packets now and then, and possible slightly larger CPU overhead to correctly map incoming packets to the right ...

compute power for MQTT vs HTTP POST in cloud
IIRC An idle TCP/IP connection shouldn't consume any power at all (relative to just having the network hardware on)
So the closest analogue to power usage is going to be bandwidth and HTTPS connection ...
