Honest Guide to Start with AWS
A Spanish-language practical guide for beginners on how to start using Amazon Web Services (AWS) without getting overwhelmed. The article walks through account creation and Free Tier limits, immediate security and billing safeguards (enable MFA on the root account, create an admin IAM user, set billing alerts, enable CloudTrail), the six core AWS services to learn first (IAM, EC2, S3, VPC, Lambda, RDS), a hands-on starter project (static website on S3 with a Lambda + API Gateway backend), AWS pricing models (On-Demand, Reserved, Spot), and a recommended certification path (Cloud Practitioner → Solutions Architect Associate → Security/AI specialties). The post emphasizes learning a small set of services, using the Free Tier for experimentation, and following least-privilege security practices to avoid surprise costs and incidents.

Key Takeaways & Evidence Grounding
- AWS Free Tier: EC2 — 750 hours/month (t2.micro or t3.micro, Linux); S3 — 5 GB standard storage plus request quotas; RDS — 750 hours/month for db.t2.micro/db.t3.micro (Single-AZ).
- Always Free tiers include Lambda: 1,000,000 invocations/month and DynamoDB: 25 GB storage with 25 WCU/RCU per month.
- Author recommends focusing initially on six core services: IAM, EC2, S3, VPC, Lambda, and RDS before exploring others.
- Immediate account setup steps advised: enable MFA on the root account, create an IAM admin user for daily use, configure billing alerts/budgets, and activate CloudTrail.
- First practical project suggested: host a static site on S3, create an IAM role for the bucket, implement a Lambda function, and expose it via API Gateway (example endpoint /api/saludo).

Cloud Computing and AWS Fundamentals Overview
This DEV.to tutorial explains core cloud computing concepts with an AWS focus, arguing cloud skills are essential for modern engineering roles (DevOps, cloud engineering, cybersecurity, backend, platform, AI infrastructure). It defines service models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid), and key AWS concepts: regions, availability zones, and the shared responsibility model. The post lists core AWS services beginners should learn (EC2, S3, VPC, IAM, ELB, Auto Scaling, RDS, CloudFormation) and provides practical getting-started steps (create an AWS free-tier account, enable MFA, use an IAM user). The guide positions AWS as the 2026 market leader due to breadth of services, global infrastructure, job market dominance, and community resources, and recommends foundational prerequisites (Linux, networking, security) before learning AWS in depth.
Amazon S3 Basics for Beginners
This technical guide introduces Amazon S3, AWS’s cloud object storage service, and explains core concepts for beginners. It covers buckets and objects, common S3 storage classes (Standard, Standard‑IA, One Zone‑IA, Glacier), and fundamental features such as high durability (11 nines), high availability, scalability, encryption, IAM and bucket policies, versioning, multipart uploads, and static website hosting. The article outlines typical use cases (images, videos, backups, logs, data lakes) and basic security and cost considerations. It positions S3 as a durable, scalable, and cost‑effective storage layer for cloud applications and previews a follow‑up hands‑on tutorial for creating buckets, uploading files, and configuring permissions.
Clear Guide to AWS Security and Storage
A dev.to technical post (published 2026-05-15) summarizes key AWS security and storage concepts aimed at AWS Cloud Practitioner exam takers and beginners. It explains AWS Config’s change recording and drift detection; distinguishes Shield Standard (free, L3/L4 DDoS protection) from Shield Advanced (paid, covers EC2, ELB, CloudFront, Route 53, Global Accelerator, includes DDoS Response Team and cost protection); and describes WAF’s L7 request-inspection capabilities and where it attaches (CloudFront, ALB, API Gateway, AppSync). The article compares WAF, NACLs, and Security Groups, contrasts EBS, EFS, S3 and Instance Store storage characteristics, highlights the Cost & Usage Report as AWS’s most granular billing feed, and lists five security services (Shield, WAF, GuardDuty, Inspector, Macie) with their primary jobs.
