Survey of Hybrid Cloud Workflow Scheduling

In the context of data explosion,traditional cloud computing is faced with the dilemma of insufficient local cloud resources and high expansion cost.However,the newly emerging hybrid cloud combining resource-rich public cloud and data-sensitive private cloud has become a research hotspot and application direction at present.As an attractive paradigm,workflow has been increasing in data scale and computing scale.Therefore,workflow scheduling is a key issue in the direction of hybrid cloud research.For this reason,this paper first makes an in-depth investigation and analysis of workflow scheduling technology in hybrid cloud environment,and then classifies and compares workflow scheduling in hybrid cloud environment:for deadline,for cost,for energy-efficient and for multi-objective constraints.On this basis,the future research directions of workflow scheduling in hybrid cloud environment are analyzed and summarized:workflow scheduling based on Serverless platform,workflow scheduling based on edge server network collaboration,cloud native workflow scheduling based on Argo integration,and workflow scheduling based on fog computing fusion.
