Edge computing, on the other hand, provides low-latency, reliable computing that can be deployed in areas with no network connections or in extreme security conditions where 3rd-party security is disallowed. However, data can become incomplete due to the higher cost of storage, and local computing has higher overall maintenance than cloud computing because it must be managed in-house.

How to provision an IoT device?
Provisioning: Each IoT Edge device must be provisioned. Provisioning is a two-step process. The first step is registering the device in an IoT hub, which creates a cloud identity that the device uses to establish the connection to its hub. The second step is configuring the device with its cloud identity. Provisioning can be done manually on a per-device basis, or it can be done at-scale using the IoT Hub Device Provisioning Service.

What is edge device?
An edge device is any piece of hardware that controls data flow at the boundary between two networks. Edge devices fulfill a variety of roles, depending on what type of device they are, but they essentially serve as network entry -- or exit -- points. Some common functions of edge devices are the transmission, routing, processing, monitoring, filtering, translation and storage of data passing between networks. Edge devices are used by enterprises and service providers.
How does an edge device work?
These can be two on-premises networks, but an edge device can also be used for cloud connectivity. The important thing to keep in mind is that the two networks are otherwise not connected to one another and might have major architectural differences. For example, at one time, it was common for organizations to use Systems Network Architecture (SNA) networks for 3270 communications in mainframe environments. As personal computers (PCs) and other devices became more prevalent, however, edge devices were used to tie Ethernet networks -- or other network types -- to existing networks.
What is an intelligent edge?
An intelligent edge device is a sophisticated IoT device that performs some degree of data processing within the device itself. For example, an intelligent industrial sensor might use artificial intelligence (AI) to determine whether a part is defective. Other examples of intelligent edge devices include computer vision systems and some speech recognition devices.
How does cloud computing and IoT help the network?
Cloud computing and IoT have demonstrated the value for pushing intelligence to the periphery of the network. If an enterprise has thousands of IoT devices, it's not efficient for them all to try to communicate with the same resource at once. Edge devices can collect, process and store data in a more distributed fashion and closer to endpoints -- hastening response times, reducing latency and conserving network resources.
What are the problems with IoT devices?
One of the problems that has long plagued IoT devices is that they can generate massive amounts of data. This data must be analyzed if it is to be of use. This can be especially problematic if the data must be uploaded to a cloud service, as doing so incurs direct costs related to the uploading, processing and storage of the data. Depending on the volume of data to be uploaded, the availability of internet bandwidth might also be an issue. Intelligent edge devices, which are sometimes referred to as IoT edge devices, can help with these problems.
What is the challenge of operating edge devices?
Device management . One of the primary challenges of operating edge devices is device management . An edge device can enable numerous additional devices to access a network. These devices might not have been registered onto the network, and they could be running operating systems (OSes) that differ from those of devices that have traditionally been used on the network. As such, organizations must consider how best to register and manage these devices.
Why is an edge device a bottleneck?
Bottlenecks. An edge device can become a network traffic bottleneck if it fails to provide enough throughput to handle the required network traffic.
How does IoT work?
IoT devices usually aren’t able to do much data processing locally. They instead send their data over the Internet to cloud computers where more resources are available to do more sophisticated analysis. They are essentially simple sensors and actuators that are Internet-accessible. They send sensor data upward to a data center somewhere and accept commands flowing downward. This tends to limit the sampling resolution and sampling frequency of the sensor data, and it usually requires significant delay after any event occurs before actions can be taken on the device. For example, IoT cameras tend to send to the cloud only relatively low resolution images at relatively low frame rates.
Why is IoT software so efficient?
It also enables very precise timing of the operations that the program performs because other processes are not competing for the processor’s attention . Software on IoT devices like these can perform “real-time” actions, allowing for extremely precise timing for its responses under all conditions. This design also often enables the IoT device to use a very small amount of power. For example, all of the Espressif devices shown above are capable of “sleeping” periodically to save power. When sleeping, they only use a few millionths of an ampere! This enables these devices to be powered for months or years on small batteries.
What is edge computing?
While IoT devices tend to run single-purpose single-process software (like the earliest computers), edge computers run real, modern operating systems, usually based upon the Linux kernel. This means that edge computers can effortlessly multitask, managing multiple applications simultaneously, supporting a wide range of popular networking protocols, and so on. In general, edge computers today can run almost anything that a server computer in a data center can run. This enables corporations to move appropriate types of application code out of their data centers and into the field.
Why are IoT devices less vulnerable to software vulnerabilities?
IoT devices are also generally less vulnerable to well-known software vulnerabilities, simply because there is no OS running well-known software. The software used on IoT devices is mostly proprietary one-off code (though it may include well-known software libraries too). Although well-known exploits may not present much risk, there have nevertheless been many cases where entire fleets of IoT devices have been commandeered by hackers and used for their own purposes against the wishes of their owners.
How difficult is it to update an IoT device?
IoT devices are usually difficult to update. Typically software updates require physical access for re-flashing. Deploying a bug fix to a fleet of devices in the field can therefore be an expensive undertaking. There are exceptions that enable remote re-flashing (Often called “Over-The-Air” or OTA updates) but this is a cumbersome and risky process. It requires more than twice as much memory as your software uses. A new software image is written into the redundant bank of memory while your existing software is managing the process from the other bank. When the other bank has been written, the machine is rebooted to pick up the new version. If anything goes wrong during this process, the device is likely to be left in an unusable state. These software update challenges are major disadvantages for remote deployments.
What is the device in Figure 1?
Recently, exceptions to that rule have begun to appear. The device near the middle of the bottom row in Figure 1, marked “ESP EYE,” is one such device. This tiny IoT device contains a small camera and it runs a neural network program to perform object detection locally on the device. It can then consume most of the generated data locally and send much lower volumes of data with higher information content upward to the cloud. This device is a perfect segue into the topic of edge computing.
Why are edge machines used?
Since edge machines have real operating systems, providing many services to applications, intelligent edge agents can be deployed on them to autonomously secure and manage their software (for example, using Open Horizon ). Edge machines can also be grouped into clusters to provide physical hardware redundancy, load sharing, and fault tolerance, often using one of the popular Kubernetes software distributions.
