Serverless computing has established itself as a compelling paradigm for developing modern cloud- and edge-native applications. Serverless represents the next step in the evolution of cloud programming models, services, and platforms, which is especially appealing due to its low management overhead, easy deployment, scale-to-zero, and promise of optimized costs. In this talk, we take a closer look at the state of serverless computing, particularly focusing on the opportunities and challenges related to building Serverless applications and systems in the edge-cloud continuum. We also present our latest work in the Polaris project, which is an open-source project hosted by Linux Foundation, that has been developing various state-of-the-art serverless approaches for the 3D computing continuum.
