A SURVEY ON FOG WITH COMPARISION TO CLOUD

ABSTRACT Fog computing is new buzz word in computing world after cloud computing. This new computing paradigm could be seen as an extension to cloud computing. Main aim of fog computing is to reduce the burden and huge data to near network edge. Fog provides data, compute, storage and application services to users like cloud. In the future all the computing data will be under the cloud. The data will be processed and sent back to the end device. Since there will be tsunami of data, cloud computing will have great hindrance like low service quality. To overcome the same, CISCO introduces a new technology called fog computing. The different characteristics of fog are low latency and location awareness,

Whenever the jet engine is connected to the internet, half an hour running time of the jet engine creates 10 TB of data. This huge data itself will create a big traffic in the bandwidth which cannot be neglected. So comes the importance of fog computing. Fog computing is complementary to cloud. Certain features of fog computing differentiate it from cloud, Fog Computing is used for real time interactions but cannot totally replace cloud computing as it is preferred for high end batch processing. As the name suggests cloud system is placed at a distant where as the fog system is placed locally near to the end user.

2. LIMITATIONS AND CHALLENGES OF CLOUD COMPUTING In comparison to the previous traditional computing paradigms, Cloud computing provides various advantages to both service providers and users but it has also some limitations and challenges.

Security and Privacy: Data security is major issues related with personal data and confidential data of organizations. User has to completely depend upon the cloud service provider for their data privacy and security.

Technical Issues: High speed internet connectivity requirement makes the system complex. Various technical issues arise during high load.

Data lock-in: The lack of standard APIs restricts the migration of applications and services between clouds. With the rise of cloud the problems of Data portability, migration and vendor lock-in situation will

CONCLUSION In this paper, we have analyzed about Cloud Computing characteristics, limitations and comparisons of cloud computing and fog computing that is probable reason for the birth of fog computing. Fog computing has the ability to handle the data tsunami created by Internet of Things. The characteristics of fog computing like mobility, proximity to end-users, low latency, location awareness, heterogeneity and due to its real-time applications fog computing platform is considered as the appropriate platform for Internet of Things.

Fog Computing is not a replacement for Cloud Computing. Fog computing resolves problems related to congestion and latency. Fog computing also provides an intelligent platform to manage the distributed and real-time nature of emerging IoT infrastructures. Till now fog computing is working as a support system to the present cloud computing systems. In future Edge concept in fog will give new opportunities and solutions to network operators and end users. Fog computing will provide better quality of service to the applications like smart grid and connected vehicles and will give new service models in future. Thus fog computing adds one more feather to IOTs
