This explainer maps the stack from workload characteristics and software/toolchain support through operating environment, cloud instance, memory, storage, and operational constraints. Examples from Windows on Arm, Ampere-based cloud services, and edge platform guidance show why latency, throughput, single-thread performance, footprint, and deployment complexity must be evaluated together. **Tags:** [Architecture](https://yomu.fyi/topic/architecture.md), [ARM](https://yomu.fyi/topic/arm.md), [Cloud](https://yomu.fyi/topic/cloud.md), [Edge Computing](https://yomu.fyi/topic/edge-computing.md), [GPU](https://yomu.fyi/topic/gpu.md), [Performance](https://yomu.fyi/topic/performance.md) ## Related reading ### [Engineering Real-Time Mobile Personalization Across iOS, Android, React Native, and Flutter](https://yomu.fyi/post/engineering-real-time-mobile-personalization-across-ios-android-react.md) - Company: [Salesforce](https://yomu.fyi/company/salesforce.md) - Author: Scott Nyberg - Published: Sep 11, 2026 - Type: Explainer Building real-time mobile personalization across iOS, Android, React Native, and Flutter required one architecture to handle different rendering models, lifecycles, identity flows, consent requirements, and release cycles without disrupting native app experiences. The team standardized schemas, event semantics, identity behavior, fallback handling, and SDK APIs, using bridge layers so React Native and Flutter could access native iOS and Android capabilities. Developers instrument apps once with constrained content zones and approved native components, while marketers configure templates, targeting, and content through Salesforce UI; metadata is published via a global CDN and rendered dynamically by the SDK. Data 360 performs server-side identity resolution and decisioning, limiting unnecessary raw profile storage on devices. An early customer implemented the system in two months and generated more than 150 million decisions within three weeks, while QR-code previews enabled testing against live profiles without app recompilation. ### [Red Hat edge platforms: Choosing the right one for your use case](https://yomu.fyi/post/red-hat-edge-platforms-choosing-the-right-one-for-your-use-case.md) - Company: [Red Hat](https://yomu.fyi/company/red-hat.md) - Author: Daniel Froehlich - Published: Sep 11, 2026 - Type: Explainer Choosing an edge platform requires balancing hardware footprint, workload needs, high availability, and operational complexity; the options range from RHEL with Podman or KVM to OpenShift clusters. The guide organizes Red Hat's offerings into RHEL-based and OpenShift-based deployments, noting that both traditional virtual machines and modern containerized workloads can coexist and that platforms can overlap as requirements grow. It details image-mode RHEL (bootc), transactional updates with rollbacks, efficient over-the-air delivery, offline installation, and dependency pre-resolution for constrained or disconnected sites. RHEL is positioned for static workloads of one to five components, while Red Hat Device Edge adds MicroShift when lightweight Kubernetes is needed. Kubernetes becomes more appropriate for larger microservices or event-driven systems, automated recovery, dynamic workloads, cross-environment scaling, and rolling updates; the series next covers OpenShift topologies. ### [CUDA Toolkit 13.4 Adds Windows on Arm Support and Greater Control over Shared GPUs](https://yomu.fyi/post/cuda-toolkit-13-4-adds-windows-on-arm-support-and-greater-control-over.md) - Company: [NVIDIA](https://yomu.fyi/company/nvidia-developer-blog.md) - Author: Jonathan Bentz - Published: Sep 9, 2026 - Type: Announcement CUDA Toolkit 13.4 extends CUDA application support to Windows on Arm and provides preview support for NVIDIA Rubin (compute capability 107), alongside updates to GPU management, CUDA Python, CCCL, Nsight tools, and core math libraries. Multi-Process Service V3 adds a scriptable CLI, named server instances, namespaces, TOML configuration, streaming multiprocessor partition controls, and cgroup-integrated GPU memory limits for shared, containerized GPU workloads. CUDA Compute Fabric Transport lets communication-library developers address named NVLink endpoints and issue asynchronous put, get, and reduction operations without mapping every remote allocation into virtual address space; it is exposed only through the Driver API. The release also decouples driver installation from the toolkit, exposes locality and unified-memory residency queries, and changes coherent platforms to CDMM by default while retaining NUMA support. ### [How Uber, OCI™, and Ampere® Co-Optimized OCI AmpereOne® M A4 Compute](https://yomu.fyi/post/how-uber-ocitm-and-ampere-co-optimized-oci-ampereone-m-a4-compute.md) - Company: [Uber](https://yomu.fyi/company/uber.md) - Published: Aug 20, 2026 - Type: Explainer Uber, Oracle Cloud Infrastructure, and Ampere co-optimized the OCI AmpereOne M A4 instance family after migrating large workloads from on-premises data centers to Arm-based cloud infrastructure. Early A1 and A2 deployments exposed dual-socket latency, Go performance degradation associated with smaller TLB and cache sizes, and insufficient single-thread performance for Gurobi services. Uber shared workload characteristics and targets that informed AmpereOne M silicon and an OCI FlexSKU, while the teams evaluated frequencies, core counts, deployment models, memory ratios, and storage. For latency-sensitive stateless services, the resulting guidance favors higher-frequency CPUs, about 8 GB per vCore, and virtual machines; throughput-oriented storage systems use parallelism, flexible memory-to-core ratios, and local NVMe or remote block storage according to locality. The collaboration is presented as improving price-performance and supporting energy-efficient, cost-optimized multi-architecture computing at scale.
