AWS & SRE Field Manual (Part 3): Amazon EC2 Architecture, Hardware Strategy & Modern Autoscaling
1. TL;DR & Problem Statement Definition: A core cloud compute service providing resizable, secure, and on-demand virtual machines (instances) with customizable hardware architectures, CPU/memory ratios, and operating systems. Problem Solved: Eliminates physical server procurement lead times (weeks to months), datacenter maintenance overhead, and capacity planning risks by enabling instant…
The report provides a comprehensive overview of Amazon EC2 architecture, hardware strategy, and modern autoscaling. It begins by defining the core service as a cloud compute solution that offers resizable, secure, and on-demand virtual machines (instances) with customizable hardware architectures, CPU/memory ratios, and operating systems.
This eliminates the need for physical server procurement, maintenance, and capacity planning risks, enabling instant provisioning for scalable infrastructure for various workloads. The report then delves into the core architecture and key components, categorizing instances into general purpose (T/M), compute optimized (C), memory optimized (R), GPU/ai (G/P), and hybrid options that can be combined with Kubernetes for workload optimization.
The report also discusses purchasing models and cost engineering strategies, outlining on-demand instances, savings plans, and reserved instances as options for cost optimization.
