      Server Description

      An entry level single core ARM64 cloud server designed for lightweight microservices basic web serving and software development testing

      General PurposeBurstable & Budget

      Amazon Web Services a1.medium is an entry-level, ARM64-based instance powered by a first-generation AWS Graviton Cortex-A72 processor. Running on the Nitro hypervisor, it features one dedicated physical core clocked at 2.3 GHz, 2.0 GB of memory, and no local storage. Benchmark results place its multi-core CPU and memory performance in the bottom ten percent, though its single-core stress-ng performance is average. Lacking advanced vector extensions but supporting AES cryptography, this instance offers a cost-efficient, dedicated-core option for ARM64 development. It is best suited for lightweight applications, basic web serving, and simple microservices. It provides a predictable performance profile without the CPU credit limitations of burstable instances, making it a stable choice for testing environments.

      Workload Profiles

      0.033Score
      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.
