Applications involving voluminous data often require that the computing be performed as close to the data source as possible due to communication constraints, privacy and sensitivity of data, latency and liveliness requirements, or costs of moving data. Given the growth in such application scenarios and the recent advances in algorithms and techniques, machine learning and inference at the edge are unfolding and growing at a rapid pace. In support of these applications, a wide range of computing platforms (hardware and software) are venturing farther away from the center and enabling computation closer to the physical world, often at the interface to the physical world. Such edge computing platforms greatly vary in computational resources, spanning from intelligent embedded devices like smart cameras, powerful on-premise systems.
The resulting diversity in edge-computing platforms in terms of capabilities, architectures, and programming models as well as the various runtime requirements and resource constraints of the various edge applications poses several new challenges. Some edge applications may need to run continuously, with pre-allocated resources, whereas others may run when particular events occur, with on-demand resource allocation. Due to the usually limited capacity at the edge in terms of computation, energy and network bandwidth, these applications need to be scheduled simultaneously and run concurrently. Consequently, a future with heterogeneous edge hardware and multiple applications sharing the underlying resources becomes imminent.
Furthermore, situations may warrant running applications in sandboxes for privacy and security. As we push more toward edge-enabled networks of devices, we inherit a setting where resources are deployed away from the safety of secure indoor spaces, often in the midst of a bustling urban canyon, and exposed to physical and cybersecurity threats. Deployed and interconnected predominantly over public networks, these systems have to be designed with cybersecurity as a first-class design citizen, rather than introduced as an afterthought, ensuring not only the integrity and confidentiality of the data, but also the correct and accountable processing of it.
Deploying and managing such applications with diverse properties at the edge in a concurrent manner requires considerations for multitenancy and presents a challenge that requires cooperation and coordination between the various components of the software stack. Mechanisms need to be devised that communicate both data and control with the applications in order to fine-tune their behavior and change their operational parameters. Realizing the computing continuum and coupling these edge applications with centrally located cloud and HPC resources and applications also opens up many research areas.
Another prominent and relevant advancement to this evolving landscape is the evolution of the last-mile wireless connectivity. The emergence of 5G and Wi-Fi 6, and the likely convergence, will initially provide a combination of bandwidth improvements, and latency reduction. Together with advancements in processor technology, this will enable us to deploy more advanced sensors, actuators and services than what is possible today. The next-generation wireless connectivity will also employ radio base stations more densely and with substantially higher computing capability for both core operations and as services for end users. The allocation and orchestration of these computing resources for various competing user needs and network functions will share many challenges currently encountered in edge-computing. Perhaps, the largest DevOps and management challenges in edge-computing at infrastructure level may be witnessed in this space.
