EC2

AWS compute: virtual machines for every workload, from microservices to in-memory databases — with Graviton processors for the best price/performance.

01 · What it is

Amazon EC2 & Graviton, made clear.

EC2 is the building block of the AWS cloud: hundreds of instance types (compute, memory, storage, GPU) in dozens of sizes, up in minutes and paid by use. With Graviton (AWS's custom ARM) performance per euro rises noticeably for compatible workloads.

AWS compute at a glance

Families for every job

M for general purpose, C for compute, R for memory, I for NVMe storage, G/P for GPUs: the choice affects costs and performance.

Graviton

AWS's ARM processors (now Graviton4): same services, less spend — the first thing we evaluate in an assessment.

Smart purchasing

On-demand for the unpredictable, Savings Plans for the stable, Spot for the recomputable: the mix is where you really save.

Nitro System

AWS's hardware hypervisor: minimal overhead, security in the silicon and tenant isolation.

03 · In depth

Families, Nitro and smart purchasing

Instances are chosen by family (M general purpose, C compute, R memory, I storage, G/P GPU) and generation: the suffix matters — 'g' is Graviton (ARM), 'i' Intel, 'a' AMD. Underneath it all is Nitro: a minimal hypervisor on dedicated hardware, freeing near bare-metal performance and isolating security. Purchasing is a strategy: on-demand for the unpredictable, Savings Plans/Reserved for the base, Spot (up to -90%) for the interruptible.

  • Nitro System — hypervisor on a dedicated card: minimal overhead, encryption and isolation in hardware
  • Graviton4 — 96-core ARM: up to 40% better price/performance on compatible workloads
  • Savings Plans — a flexible $/hour commitment across family and region: the discount without the rigidity of old RIs
  • Spot — unused capacity at -70/90%: batch and workers with managed interruption (2-minute notice)
  • Placement group — cluster, spread or partition: the topology for HPC or anti-affinity
  • EBS gp3 — IOPS and throughput independent of size: the right default, not gp2

05 · Use cases

Where it really pays off.

Lift-and-shift

The first step of migration: the VM as it was, but elastic and replicable across zones.

Seasonal peaks

Capacity that switches on for the campaign or month-end and off afterwards: you pay for use, not for the peak.

Test environments

Entire environments created and destroyed on command: testing without dedicated iron.

Continuous right-sizing from our NOC: instances observed, resized and repurchased on the right plan — the cloud costs what it should.
