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.
Introductory technical tutorial on a foundational cloud storage service — useful background for engineers but not industry‑shifting news.

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.
S3-Compatible Storage Explained (2026)
This technical explainer defines what “S3-compatible” means in 2026, why Amazon S3 became the de facto object-storage API, and how different implementations vary. It lists core S3 operations and Signature V4 authentication as the compatibility baseline, contrasts guaranteed AWS features with typical compatible systems, and surveys cloud and self-hosted S3-compatible options (Amazon S3, Wasabi, Backblaze B2, MinIO, RustFS, Ceph RGW, SeaweedFS, Garage). The article gives guidance for choosing based on scale, licensing, workload, and operations, highlights production differences (headers, error codes, multipart uploads, event notifications, performance), and includes a RustFS single-node example and a comparative feature matrix accurate as of July 2026.
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.
