Abstract: The lack of function-oriented power management scheme has seriously hindered the serverless platform’s cost efficiency. In this paper, we analyze the invocation pattern of serverless functions and investigate its implications on server energy efficiency. Rather than using a one-size-fits-all strategy, we propose DAC, a software-hardware co-design solution to offer differentiated cloud-native server consolidation. We build a proof-of-concept framework and show that DAC can improve the energy efficiency of tail function deployment by up to 23%.
