CLOUD SERVERS AND FOG OR EDGE COMPUTING WITH THEIR LIMITATIONS & CHALLENGES

Cloud computing suits to be a best dominated technology for interconnection of numerous servers and computers over internet. Cloud sets broad room for much small scale to large scale industries and Organizations to manage, store, process and run their applications. Although Cloud continued to be efficient for its services but at the same time it rises with certain limitations. This paper focuses on cloud limitations like Data maintainability, network elasticity, managing IoT’s, user privacy, cloud security, uninterrupted access of data among various Internet of Things (I.o.T.), unawareness of location and many more which give birth to Fog Computing. Fog continued to access & fares similar applications or services of cloud over the edge of the network. Fog or decentralized cloud accomplish the challenges like Substantial storage, low latency, heterogeneity, communication with various IoT devices, improved security, control configuration and so on. This paper examines measuring parameters of cloud and fog along with their architecture.
