Fog Computing Vs Cloud Computing: The Role in IoT

Fog computing is the extension of cloud computing. Cisco developed the network of Fog computing in 2014. Fog computing is also renown as Edge computing or fogging. It facilitates the process of the computer, networking services, and storage between cloud computing data centers and end devices. Fog computing makes the process of IoT more easy and efficient cloud data processing.

Cloud computing process the data of a remote server across the internet. It manages, stores and uses data from a local computer. When the user thinks that it is easy to use the vendor’s computer, service and storage then cloud computing fulfill the demand of the user. In cloud computing, there are SaaS, IaaS and PaaS service. On the other hand, several types of a network like private cloud, public cloud, and hybrid cloud are available there.

IoT is elaborate as the internet of things. The concept of IoT is each and every device connects to the internet and a server. The process can be used through fog computing or cloud computing. When the end user sends a request to the server through his/her smart gadget then the order will execute from anywhere in the world. Actually, IoT has the same concept of for computing or cloud computing.

Fog Computing Vs Cloud Computing


Fog Computing Vs Cloud Computing The Role in IoTThough Fog Computing and Cloud Computing seem to be the same there is a lot of difference. Some of the differences are as follow. We consider also the IoT review to make the differentiation:

Latency

Fog computing network has low latency. On the other hand, Cloud Computing has low latency but not so much low as Fog Computing.

Capacity

The main benefit of fog computing that it reduces the volume of data sent to cloud computing. Cloud computing is just to keep the backup. It does not reduce any data.

Bandwidth

Fog Computing protects the volume of bandwidth. On the other hand, Cloud computing saves less compared with Fog Computing.

Responsiveness

In Fog Computing, the response time of the system is very high. In contrast, In Cloud Computing, the Response time of the system is low.

Security

Fog computing has high Security. On the other hand, security of cloud computing is high but less compared to Fog Computing

Speed

The first one is high even more compared to the second one. It depends on the VM connectivity.

Data Integration

In Fog, multiple Data devices and Source can be integrated. In the cloud, multiple data sources can be integrated.

How Fog Computing Works


The entire process of fog computing happens inside a data hub on a smart gadget. This technique is useful at IoT or internet of things by using the sensor. Where there is a huge volume of data and not enough to give away all the data then the bunch of sensors causes the cloud for analysis and process. There is a great requirement of bandwidth in cloud computing but fog needless.

The high-end device and sensors produce data and do not have the storage capacity to analysis task and machine learning. Although, cloud server has that power to process but needs time to get the response from the cloud server. At the endpoint, the collection and sending of data from the cloud server are managed by different countries. Data security and confidentiality may lose if the hostile country wants.

In foggy computing, the processing occurs in the data hub on an intelligent gateway, intelligent router or intelligent device. The fact is, cloud computing component remains the same, no change on its configuration. Finally, the fog server transmits data to a cloud server. So fog computing is called the extension of cloud computing.

How Cloud Computing Works


Cloud computing can break down into two sections: front end and back end. It is connected with a network over the internet.  The front end is the consumer end or client computer. The back end is connected withthe cloud server.

The client computer that means the front end requires software application to access the computer processing system. It is not required to have all the client device the same application or same interface. At the cloud server end varieties of the cloud server, data storage systems and different network make up the “Cloud”.

Different software as a service, infrastructure as a service and developing the platform as a service known as cloud computing. Real-time video games, business intelligence software are examples of cloud computing.

Pros of Cloud Computing


Lover Cost

In cloud computer application run inthe cloud so need less hardware cost. The desktop does not need any extra processing power.

Improve performance

In cloud computing the processing speed is high. So the performance is high. It takes a few memory to process.

Reduce software cost

In cloud computing software can be taken as a rental basis. Software as a service can reduce the cost of your organization.

Up-to-Date Software

Cloud computing service providers offer various high-cost software. Since they specialized, so all the software are up-to-date.

Improved Document Format Compatibility

The vendors takes money so it is their responsibility to provide all support. The device support all the document format.

Cons of cloud computing


Common infrastructure restriction

In cloud computing, you get to access all the global linked available resource. You have to experience with “Noisy Neighbor” in this process. However private cloud can reduce the risk. Internet connection is another vital factor which have to address.

Security issue

The recent iCloud resk is obviously anxious. Advanced encryption and firewall systems can solve this problem.

Pros of Fog Platform


Both the computing have some benefit but the fog has something different. The advantage of for computing compare to cloud computing are:
• Minimize latency: This computing minimizes latency than any other computing.
• Conserve network bandwidth: Compare to other cloud network fog is more Conserve network bandwidth.
• Address security concerns: Security is the vital concern for at all level of the network. So fog is more repayable for security.
• Fog computer operate reliably with quick decisions
• This computing collect and secure the wide range of data
• Fog move data to the best place for processing
• Another vital advantage is lower expenses of using high computing power using less bandwidth
• Better analysis and insights of local data

Cons of Fog computing


Physical location

In cloud computing, all the data is accessible from anywhere from the world. But in fog computing, there is a restriction of sharing data.

Safety

In fog computing, there is a different platform. Some expert things that there is a safety issue of data on the decentralized network.

Confusion

There is a lot of network like private, public, hybrid, different protocol makes confusion to the general mind.

Final Thought


Fog computing and cloud computing is used in IoT. The pros and cons of both are the best explanation of IoT requirement. When the speed is the first priority then fog computing is a must. On the other hand, where data need more security there need cloud computing of IoT. Moreover for computing is a device to devise network but cloud computing is the the server to server network. In IoT people are more focusing on fog computing.
