“…We characterized H-Container costs on a set of benchmarks collected from different projects. Based on previous works [1,36,43,55,56,58,81,93] we believe such set of benchmarks well represents compute/memory workloads that can be found at the edge. The focus on compute/memory workloads is motivated by the necessity of spotting compiler/runtime overheads, not OS ones.…”

Edge computing is a recent computing paradigm that brings cloud services closer to the client. Among other features, edge computing offers extremely low client/server latencies. To consistently provide such low latencies, services need to run on edge nodes that are physically as close as possible to their clients. Thus, when a client changes its physical location, a service should migrate between edge nodes to maintain proximity. Differently from cloud nodes, edge nodes are built with CPUs of different Instruction Set Architectures (ISAs), hence a server program natively compiled for one ISA cannot migrate to another. This hinders migration to the closest node.We introduce H-Container, which migrates natively-compiled containerized applications across compute nodes featuring CPUs of different ISAs. H-Container advances over existing heterogeneous-ISA migration systems by being a) highly compatible -no source code nor compiler toolchain modifications are needed; b) easily deployable -fully implemented in user space, thus without any OS or hypervisor dependency, and c) largely Linux compliant -can migrate most Linux software, including server applications and dynamically linked binaries. H-Container targets Linux, adopts LLVM, extends CRIU, and integrates with Docker. Experiments demonstrate that H-Container adds no overhead on average during program execution, while between 10ms and 100ms are added during migration. Furthermore, we show the benefits of H-Container in real scenarios, proving for example up to 94% increase in Redis throughput when unlocking heterogeneity.CCS Concepts: • Computer systems organization → Heterogeneous (hybrid) systems; • Software and its engineering → Operating systems.

Edge networking has become an important technology for providing low-latency services to end users. However, deploying an edge network does not guarantee continuous service for mobile users. Mobility can cause frequent interruptions and network delays as users leave the initial serving edge. In this paper, we propose a solution to provide transparent service continuity for mobile users in large-scale WiFi networks. The contribution of this work has three parts. First, we propose ARNAB architecture to achieve mobile service continuity. The term ARNAB means rabbit in Arabic, which represents an Architecture for Transparent Service Continuity via Double-tier Migration. The first tier migrates user connectivity, while the second tier migrates user containerized applications. ARNAB provides mobile services just like rabbits hop through the WiFi infrastructure. Second, we identify the root-causes for prolonged container migration downtime. Finally, we enhance the container migration scheme by improving system response time. Our experimental results show that the downtime of ARNAB container migration solution is 50% shorter than that of the state-of-the-art migration.
