      Server Description

      An eight-core ARM-based server instance with dedicated vCPUs and 16 GB memory optimized for entry-level scale-out workloads and containerized microservices.

      Compute OptimizedGeneral Purpose

      Amazon Web Services a1.2xlarge is an ARM-based instance equipped with 8 dedicated AWS Graviton physical cores based on the Cortex-A72 architecture, operating at 2.3 GHz on the Nitro hypervisor. It provides 16.0 GB of RAM (2.0 GB per core), a 2 Gbps baseline network bandwidth, hardware AES acceleration, and no local SSD storage. Benchmark evaluation shows average multi-core CPU performance in stress tests alongside weak memory bandwidth speeds, measured at 23.51 GB/sec read and 8.88 GB/sec write. Due to the first-generation Graviton architecture and modest single-threaded throughput, the instance exhibits lower performance in compute-heavy or vector-intensive applications. However, its dedicated core design offers predictable execution for lightweight, scale-out ARM workloads. It is best suited for basic web serving, containerized ARM microservices, lightweight Redis caching, and entry-level Linux cloud applications.

      Workload Profiles

      0.18Score
      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.
