Key Concepts to Understand
AWS organizes its infrastructure around regions and availability zones, geographically distributed data centers designed to keep workloads resilient even if a physical location has an issue. Core services like EC2 (compute), S3 (object storage), RDS (managed databases), and VPC (networking) form the foundation that most architectures are built on. IAM (Identity and Access Management) controls who can do what across every service and is one of the most important things to get right from day one. Understanding how these foundational services relate to each other is the starting point for working effectively in AWS.
Important Considerations
AWS pricing is consumption-based, which means costs scale with usage, in both directions. Reserved Instances and Savings Plans can significantly reduce compute costs for predictable workloads, but require upfront commitment and planning. Data transfer costs in particular catch teams off guard; moving data out of AWS is not free, and architectures that generate high egress volumes need to account for this. Cost visibility tools like AWS Cost Explorer and budgets and alerts are not optional in production environments.
Planning and Design Principles
Well-architected AWS environments are built around five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. In practice, the most common gaps we see are in security (overly permissive IAM roles, public S3 buckets) and cost (underutilized resources, forgotten services). Designing for failure from the start, using multiple availability zones, auto-scaling groups, and managed services where appropriate, is significantly easier than retrofitting resilience into an architecture that wasn't built with it in mind.
Key Capabilities
What AWS Brings to the Table
Global Infrastructure at Any Scale
Deploy workloads across 30+ regions and 90+ availability zones, with the network backbone to support global applications reliably.
Broadest Managed Service Catalog
From AI and machine learning to IoT and media processing, AWS offers managed services that remove infrastructure management from nearly every workload type.
Granular Identity and Access Management
IAM provides fine-grained control over every API call, resource, and user action across the entire AWS environment.
Mature Cost Management Tooling
Cost Explorer, budgets, anomaly detection, and Savings Plans give teams the visibility and controls needed to manage cloud spend at any scale.
Fit Check By Use Case
Startups and High-Growth Applications
AWS's pay-as-you-go model and elastic scaling make it well suited for workloads that need to grow fast without upfront infrastructure investment. Examples: SaaS products, consumer applications, e-commerce platforms
Enterprise Workload Migration
AWS has the tooling, compliance certifications, and partner ecosystem to support large-scale migrations from on-premises infrastructure. Examples: Data center consolidation, SAP migrations, enterprise application re-hosting
Cost-Sensitive Workloads
AWS can be cost-effective, but it requires active management. Without reserved capacity planning and cost governance, it's easy to overspend relative to alternatives. Prerequisites: Cost management tooling in place, reserved instance strategy, regular spend reviews
Highly Regulated Industries
AWS holds a broad range of compliance certifications, but regulated workloads require careful architecture and configuration. Compliance in the cloud is a shared responsibility. Prerequisites: Compliance-specific architecture review, appropriate AWS service selection, documentation
Teams Without Cloud Expertise
AWS rewards experience. Teams without cloud-native skills often find costs and complexity spiral quickly without the right guardrails and governance from the start. Examples: Organizations without dedicated cloud or DevOps capability
Simple, Predictable Workloads With Fixed Requirements
For straightforward, stable workloads with no scaling requirements, simpler and cheaper hosting alternatives may deliver better value without the operational overhead of AWS. Examples: Static websites, simple line-of-business applications, small internal tools
How Crafty Penguins Uses Ceph Storage
AWS is one of the platforms we work with most frequently, and our involvement varies considerably depending on where a client is starting from. For some clients, we're helping design and build AWS environments from scratch, making foundational decisions around account structure, networking, security, and service selection that will shape everything that follows. For others, we're coming into environments that have grown organically and need rationalization: tightening IAM policies, reducing unnecessary spend, improving resilience, or building the observability layer that should have been there from the start. We're also regularly involved in helping clients navigate AWS alongside their on-premises infrastructure, designing hybrid architectures that make practical use of both without overcomplicating the operational picture.
