Rise of the Planet of Serverless Computing: A Systematic Review

Serverless computing is an emerging cloud computing paradigm, being adopted to develop a wide range of software applications. It allows developers to focus on the application logic in the granularity of function, thereby freeing developers from tedious and error-prone infrastructure management. Meanwhile, its unique characteristic poses new challenges to the development and deployment of serverless-based applications. To tackle these challenges, enormous research efforts have been devoted. This paper provides a comprehensive literature review to characterize the current research state of serverless computing. Specifically, this paper covers 164 papers on 17 research directions of serverless computing, including performance optimization, programming framework, application migration, multi-cloud development, testing and debugging, etc. It also derives research trends, focus, and commonly-used platforms for serverless computing, as well as promising research opportunities

Solving signaling storms in LTE networks: a software-defined cellular architecture

The LTE network infrastructure is composed by monolithic devices that carry out a convoluted set of tasks in a vendor-speci c manner. Therefore, LTE networks are largely in exible, and consequently unable to adapt to a constantly increasing number of mobile subscribers and the changeable usage pattern of the Internet service. In fact, current LTE networks are a ected by signaling storms, which come from the inability to reduce the number of signals exchanged among the infrastructural elements of the network when the number of subscribers' requests grows. In this work, we propose a software-de ned cellular architecture, whose logical entities can be mapped to an arbitrary number of physical devices, allowing di erent implementations depending on the speci c use case. In particular, we show that the proposed model actually mitigates the impact of signaling storms, as it can be tailored to reduce signi cantly the number of signals owing in the network during the occurrences of the most frequent network events
