What this skill does
Oracle Cloud Performance Tuning Overview Navigate OCI's opaque shape naming, block volume performance tiers, and shape-dependent network bandwidth. OCI shapes like VM.Standard.E5.Flex, VM.Standard3.Flex, and VM.Standard.A1.Flex look similar but have wildly different performance profiles. Block volume tiers (Balanced, Higher Performance, Ultra High Performance) have different IOPS and throughput limits that are easy to get wrong. This skill maps performance characteristics to shapes and storage tiers so you can make informed infrastructure decisions. Purpose: Choose the right compute shape and storage tier for your workload by understanding OCI's performance characteristics, and monitor those resources programmatically. Prerequisites OCI tenancy with an API signing key in ~/.oci/config Python 3.8+ with pip install oci Compartment OCID for querying available shapes and metrics Basic understanding of IOPS, throughput, and OCPU concepts Instructions Step 1: Understand Shape Naming OCI shape names encode processor generation, type, and flexibility: Shape Processor OCPUs Network Gbps per OCPU Best For ------- ----------- ------- ---------------------- ---------- VM.Standard.E5.Flex AMD EPYC 9J14 (Genoa) 1–94 1 Gbps General workloads (latest gen) VM.Standard.E4.Flex AMD EPYC 7J13 (Milan) 1–64 1 Gbps General workloads VM.Standard3.Flex Intel Xeon (Ice Lake) 1–32 1 Gbps Intel-optimized software VM.Standard.A1.Flex Ampere Altra (ARM) 1–80 1 Gbps ARM-native, cost-efficient VM.Optimized3.Flex Intel Xeon (Ice Lake) 1–18 4 Gbps HPC, network-intensive BM.Standard.E5.192 AMD EPYC 9J14 192 100 Gbps total Bare metal, full isolation Key insight: Flex shapes let you choose OCPU and memory independently. Memory defaults to 1 GB/OCPU min, 64 GB/OCPU max (varies by shape). Network bandwidth scales linearly with OCPUs up to the shape maximum. …
