      Server Description

      An entry-level ARM64 instance featuring dedicated Graviton cores and balanced memory for lightweight development and basic scale-out workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services a1.large is an ARM-based instance powered by a first-generation AWS Graviton processor with 2 dedicated physical cores using the Cortex-A72 microarchitecture. Operating at 2.3 GHz, it features 4.0 GB of system memory, a 1 Gbps baseline network speed, and no local storage or GPU accelerators. Benchmark results indicate modest single-core CPU capabilities, while multi-core performance, memory bandwidth, and database operations fall into the lower performance tiers. This instance represents a cost-effective entry point for ARM64 development, testing, and lightweight scale-out workloads. It is best suited for basic web serving, containerized microservices, and software compilation tasks optimized for ARM architectures where high memory throughput is not a critical requirement.

      Workload Profiles

      0.053Score
      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.
