We all know about data existing in the cloud, but have we ever wondered from where this data comes from? Indeed, we use existing data in the cloud and process it with different software which further helps in performing analytics, but we never cared about the origin of the data.  Of course, the data is created by humans in our operating environments while interacting, computing, or performing various tasks. With time, everything upgraded including the information and its computing demands. The rise of real time computing demands has forced the technology drivers to rethink on the cloud computer architecture and relocate it from centralized to distributed servers. Thus, the concept of Edge computing came into action.

What is Edge Computing?

What is Edge Computing?

The computing that occurs by placing workloads at the edge of corporate networks where the data is being created is known as Edge Computing. The “edge” is defined as the position where the end devices can access the rest of the network devices like laptops, phones, desktop, machines, routers, and sensors. This technology is used to connect IoT devices so they can deliver data efficiently, receive instructions quickly, and download software updates from a cloud or a data center without any hassle. Edge computing is a new approach to network architecture where first in cloud computing continues to play an important role and secondly the new possibilities offered by IoT devices which are capable of processing the data are forcing companies to rethink their approach to IT infrastructure. Edge devices collects, sorts, and performs the analysis of the data and after processing stores the data it to its destined place.

What is Edge Computing?

Edge Computing is an open distributed computing paradigm that ensures speedy computation, handles data activities, network operations and data storage. It brings the devices closer to the place as a result improving the post time and saving bandwidth. It features decentralized processing power enabling mobile computing and Internet of Things.

The Edge computing data is either processed by the device itself or by a local computer or server rather than being directly transmitted to a data center. The data computing occurs at the Edge of the device or at the location where data is generated. Thus, it significantly improves the speed of data processing by reducing the data travelling between devices and centralized cloud data centers.  This technology opens a platform for us to communicate into the premises where the work is performed unlike the warehouses, retail store, supermarket, banks, etc,.With the outbreak of the Internet of things or IoT devices, there is a bulk of data present in the centrally located data centers or cloud. Hence, it requires larger and expensive connections to maintain the sheer volume of data. The work performed by these IoT devices creates a need for much faster connections between the data center or cloud and the devices.

For example, in a petroleum refinery station, the valves’ sensors detect the dangerously high pressure in the pipes. In that case, the shutoff for the supply of petroleum must be called off immediately. The automatic shut may delay the shutoff process as it takes time to analyze that pressure taking place at distant processing centers. But we can prevent this delay by placing the processing power locally to the end devices. It will minimize the latency, reduce the roundtrip time, and will save the downtime. Thus, causing less damage to man, money, and material. 

The key component of cloud computing is to maintain the security and balancing the stability if there is any failure in its connections. In case of Edge Computing as well, security is at utmost importance as these devices come across various network elements and hold confidential data, if exploited, could compromise other devices as well that contain valuable assets. Edge computing makes sure that the edge devices themselves become a single point of failure network architect by building redundancy and provide failover contingencies in order to avoid crippling downtime.

The edge computing devices are Raspberry Pi 4 B Model, LattePanda Alpha, UDOO Bolt, Jetson Nano (Nvidia), and Intel Neural Compute Stick 2.

What is Need of Edge Computing?

For over a decade centralized cloud computing was consistent and has revolutionized a standard platform to read, write, store, and fetch data. It has a strong data centric architecture where resource storing, and computational operations were efficient and scalable. The cloud has become an indispensable part of data processing and storage.  

What is Need of Edge Computing?

But with technology and internet, the era witnessed colossal growth of information known as ‘Internet of Things’. IoT generates incomplete data, which further needs to be processed and answered in a very short time. Resulting with a sudden rise in real time computing demands but with cloud computing the cost for generating the data also increased exponentially. However, the cloud that has been centrally linked on a global scale to process enormous data. Besides, if the physical distance between the user and the cloud increases, it raises the transmission latency and increases the response time, as a result stressing out the user.

On top of that, cloud has only some limited access. Network convergence, streaming videos and internet usage continues to trend towards bandwidth insensitive content, offline access to programs and latency sensitive applications in an increasing demand for cloud services. The solution to these problems is to relocate the cloud computing and data storage to Edge Computing Platform. The edge computing platform works by allowing application processing to be performed by a small edge server position between the cloud and the user. The network edge lowers the data transport time and increases the availability. The objective of this technology is to compute logics and data to edge network so the data will not return to the central server every time the function is execute by an IoT device. This technology allows some of the workloads to be offloaded from the cloud server and push it closer to the user’s devise for processing. Thus, speeding up application’s response time and maintains a low latency response.

Cloud Computing V/S Edge Computing

Edge computing is known as one of the new trendsetters that have raised 5G Wireless technology. Indeed, 5G entails an enormous group of networks wired together with optic fiber connections to provide transmitters and base stations with prompt access to digital data. People often uses cloud computing and edge computing interchangeably. But both are diverse and have different functionalities as given below:

In Cloud computing, the IoT devices generate the data and save it to a centralized cloud server for further data processing. This happens every time whenever a new data is generated.                     With Edge computing, the edge interface comes in between IoT devices and cloud servers. This edge could be directly connected with the IoT device or configure the closest possible to the device. The objective of this technology is to compute logics and data to edge network so the data will not return to the central server every time the function is execute by an IoT device.
In cloud computing, the data process is initiated through Centrally Managed System (CMS), which makes the processing more time-dependent and less efficient.In the case of edge computing, the initial processing is done by the “edge,” while a Centrally Managed System carries rest.
The files or applications present in the cloud processing are directly accessed from the server.In edge computing, the processing is done on the “edge” network.
This technology is used to access the back-end data that might not be efficient enough to provide real-time monitoring and analysis.Edge Computing is used for the real-time analysis and monitoring of data.
The data processing is happening on the serving, which is far away from the devices. Thus, it increases the data latency and consumption of network bandwidth.The edge computing is used to reduce network latency and enhance its speed and performance. The speed and flexibility of this technology is used for handling data by creating an exciting range of possibilities for organizations.
Cloud computing technology processes the data that is not driven by time.Edge computing technology processes time-sensitive data.
