      Server Description

      An entry-level, dedicated ARM64 instance designed for cost-efficient application testing, basic web serving, and lightweight containerized workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services a1.xlarge is an ARM-based instance powered by the first-generation AWS Graviton processor. Operating on the Nitro hypervisor, it features 4 dedicated physical cores and 4 vCPUs utilizing the ARMv8 Cortex-A72 architecture at 2.3 GHz, paired with 8.0 GB of RAM. The instance lacks local storage and GPU accelerators, and provides a baseline network bandwidth of 1 Gbps. Performance benchmarks place the instance in the lower tiers, with a weak multi-core stress-ng score of 5919.11 and constrained memory read/write bandwidths. Lacking advanced vector extensions or hyperthreading, the a1.xlarge represents a cost-efficient, entry-level option for ARM64 development. It is appropriate for lightweight workloads, including basic web serving, application testing, and simple containerized microservices.

      Workload Profiles

      0.098Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
