Fog and cloud both the computing platforms offer the company to manage their communication effectively and efficiently. Fogging, also known as fog computing, is an extension of cloud computing which imitates an instant connection on data centers with its multiple edge nodes over the physical devices. It establishes a missing link between cloud computing as to what data needs to be sent to the cloud and internet of things and what data can be processed locally over different nodes.
Fog networking or edge computing is a decentralized infrastructure where data is processed using an individual panel of the networking edge rather than hosting or working on it from a centralized cloud. It provides access to the entry point of the different service providers to compute, store, communicate, and process data over the networking area.
It is difficult for a cloud platform to respond on time to each device, sensor, and application on time as a large amount of data is generated and transferred over the internet. Fog computing is deployed by using nodes over the network. Firstly the signal is transmitted from an IoT device, and then data is sent through a protocol gateway at each node. The data is processed at the end of the nodes on the smart devices to segregate information from different sources at each user’s gateways or routers.
Benefits of Fog Computing:
- It is less expensive to operate with fog computing as data is hosted and analyzed on local devices rather than transferring it to any cloud device.
- It helps to facilitate and control business operation at par by deploying fog application as per the user’s need.
- Fogging offer different choices to users for processing their data over any physical devices.
Cloud computing is an on-demand deliverability of hosted services over the internet. It allows users to access information over the remote location rather than being restricted to a specific place.
The working of cloud computing is divided into two components, which include front end layer and back end layer. The front end is the user side, which allows accessing data present in the cloud over the browser or the computing software. The back end is the system cloud section which is responsible for securing and storing data. Both these components are integrated to provide the user with a seamless networking platform and manage traffic on the ground.
Benefits of Cloud Computing:
- It works on a pay-per-use model where users have to only pay for the services they are availing for a given period.
- In Cloud user can increase their functionality quickly by accessing data from anywhere as long as they have net connectivity.
- It enhances cost saving as workloads can be shifted from one cloud to other cloud platforms.
Difference between Fog Computing and Cloud Computing:
- In fog computing data is received in real-time from IoT devices using any protocol.
- Cloud computing receives and summarizes data from different fog nodes.
- Fog has a decentralized architecture where information is located over different nodes at the user’s closest source.
- Cloud has a large amount of centralized data centers which make it difficult for the users to access information at their closest source over the networking area.
- Fog is a more secure system as it has various protocols and standards which reduces its chance of being collapsed while networking.
- As the cloud runs over the internet, its chances of collapsing are high in case of undiagnosed network connections.
- Fog has some additional features other than the ones provided by cloud’s components which enhance its storage and performance at the end gateways.
- Cloud has different parts like front end platform (e.g. mobile device), back end platforms (storage and server), cloud delivery and network (internet, intranet, intercloud).
- The response time of the system here is relatively higher than that of cloud as fogging firstly segregates the data and then sends it to cloud.
- Cloud doesn’t provide any segregation in data while transmitting data at the service gate, thereby increasing the load and thus making the system less responsive.
- Edge computing can be used for smart cities traffic management, automating smart buildings, visual security, self-maintaining train, wireless sensor networks, etc.
- Cloud computing can be applied to e-commerce software, word processing application, online file storage, web application, creating image album, diverse application, etc.
The demand for information is rising overall networking channels. And to cope with this, services like fog computing, and cloud computing are utilized to manage and transmit data quickly to the users’ end.
However, fog computing is a more viable option in terms of managing a high degree of security patches and reducing bandwidth issues. Fog computing allows to locate data over each node on local resources and thus making the analysis of data more accessible.
