Fog Computing Versus Cloud Computing – What Are The Differences?

    fog computing verses cloud computing

    With increasing numbers and types of databases and also the amount of data contained in them, there also arises the need for newer and more effective ways to deploy all kinds of available data to all the people who desire them. Cloud computing is one of the deployment systems that many of us might be well acquainted with. At least, we have heard about clouds. But there are other computing systems as well. One such computing method is fog computing. What is it, and how does it differ from conventional cloud computing? No need to fluster yourself with all these questions about the definition of fog computing and so on. We have brought to you a basic idea about what fog computing is and about the differences between fog and cloud computing. It all awaits you just a few scrolls below!

    What is fog computing?

    Fog computing is a system of networking that consists of a decentralized computing architecture. This structure is situated between the devices that produce data and the cloud. A fog computing architecture is quite flexible in nature and lets users please resources and applications of their choice in statistically decided locations that would help them to better their performance and services.

    Any device that has storage, good network connectivity, and can compute data can be considered as a fog node. Industrial controllers, routers, surveillance cameras, and embedded servers are some of the many examples of devices that make use of fog computing tools.

    What is cloud computing?

    Unlike fog computing, cloud computing makes use of a centralized processing network. Cloud computing refers to the system of maintaining and using a mesh of remote servers that are hosted on the internet. These servers consist of data and deploy them to clients as and when they require or demand the same. 

    Examples of cloud computing systems are all around us. Starting from Google searches, to big data analytics, almost all Internet resources around us use cloud computing.

    What are the major differences between fog computing and cloud computing?

    Although both the systems of cloud computing and fog computing might look the same to you at first, they are quite different from one another. However, the differences between the two systems are not as prominent as hell and heaven. They are more like jam and Jelly. They look the same, but their foundations are quite different. Well, that might have been a weird comparison, but we assure you that you will understand what exactly we mean in a minute.

    1. One of the basic differences between fog computing and cloud computing is the architecture of the systems. Fog computing has a highly decentralized system. The most fundamental criterion of fog computing is that it makes use of a distributed infrastructure. Cloud computing on more occasions, though, portrays the ultimate centralized processing systems.
    2. Another one of the major differences between fog and cloud is that fog is more of a mediator between the hardware and data centers. It is situated much closer to end-users. Clouds are no such mediators.
    3. Cloud computing processes data stored in physically isolated servers. Fog computing on the other hand makes use of storage that is situated on the edge of the network, closer to the source of data (therefore also saving time). 
    4. The last two points of difference that we have discussed also lead us to the conclusion that fog computing takes much lesser time. Cloud computing on the other hand is a much more time-consuming process. Fogs have lower latency than clouds. Fog computing makes use of systems that are important for reducing time consumption and providing faster services to the users. 
    5. Cloud storage capacities and computing capabilities are quite better than fog computing, though. Fogs can perform short-term edge analysis only. Clouds can perform over larger distances.
    6. Another one of the important points of distinction between cloud and fog computing is that a cloud system is heavily dependent on Internet connectivity. Fog computing on the other hand can make use of multiple other protocols as well.
    7. Fog computing is also a more secure process because of its distributed structure. In the case of cloud computing, you need to take certain security measures separately to ensure the privacy of data stored in the clouds. 

    You have just gone through the above is a simple layout of the differences between cloud and fog computing. There are other points of distinction that you can draw from the above points as well. The above however are the basic and the major points of the difference between the two processes. We hope we could make it clear.
