CEC enables faster processing of data and provides multiple benefits, including scalability, data security, and improved quality of service. With the increasing demand for real-time data processing, the proliferation of the Internet of Things (IoT) devices, and the growing need for data privacy and security, CEC has been developing, evolving, and adapting quickly. Cloud computing provides scalable and flexible computing infrastructure, while edge computing offers low latency and location-awareness capabilities.How to schedule the tasks in a CEC among its exploding amount of resources is a challenge for both service providers and users. QoS (quality of service) or QoE (Quality of experience) are metrics that describe this process and are often adopted as the optimization objective. Among all kinds of resource management optimization approaches, learning-based task scheduling and offloading have gained popularity in recent years. To overcome these limitations, researchers have turned to machine learning techniques to develop more intelligent and adaptive resource management algorithms. However, the machine learning-based methods in CEC also face several challenges:1. The performance of learning-based resource management is difficult to maintain when the pattern of time-critical tasks is dynamically changing;2. Learning-based resource management strategies are difficult to adapt when continuum resources are highly heterogeneous;3. Learning-based resource management suffers from low robustness when optimizing multiple objectives.My thesis tackles these challenges, and we propose a Meta-Learning-based resource management framework to deal with time-critical requests spanning from independent tasks to complex workflows in a dynamic cloud-edge continuum. Our goal is to improve the robustness and adaptivity of the resource management framework in highly changing environments."--
