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.
Foundational cloud and AWS knowledge underpins modern AdTech/MarTech infrastructure (hosting, data processing, analytics). The article is educational rather than a platform policy or technical release from a major vendor, so it has modest but real relevance for practitioners.

Why Developers Should Learn Cloud Computing
This educational article argues that cloud computing is an essential skill for modern developers. It defines cloud computing as the delivery of services (servers, storage, databases, networking, software, and intelligence) over the internet and highlights core benefits—scalability, pay-as-you-go cost efficiency, and global reach via distributed data centers. The piece includes a practical example showing a simple Node.js “Hello World” AWS Lambda handler and the AWS CLI create-function command to deploy it. Recommended learning paths include online courses (Coursera, Udemy, edX), vendor documentation (AWS, Google Cloud, Azure), and hands-on projects such as deploying static sites or serverless chatbots. The article frames cloud adoption as a career-expanding step toward roles like DevOps and cloud architecture.
AWS Skills Developers Should Master in 2026
This article outlines the core AWS skills developers and cloud engineers should prioritize in 2026. It argues that understanding cloud architecture and how services combine is more valuable than memorizing individual services. The post covers foundational topics (EC2, S3, RDS, VPC), operational patterns (load balancing, auto-scaling, monitoring, security), and modern approaches (serverless with Lambda, containers/Kubernetes, Infrastructure as Code with Terraform). It recommends a phased learning roadmap from fundamentals to production readiness and emphasizes hands-on projects, automation, observability, and secure design. The author also links to paid learning resources for further study.
AWS Cloud Practitioner Essentials Module 1 Summary
A Dev.to post by author Pradhum describes their experience completing Module 1 of the AWS Cloud Practitioner Essentials course. The article summarizes foundational AWS concepts: cloud as on-demand, pay-as-you-go IT resource delivery; the utility model for computing; AWS global infrastructure including Regions, Availability Zones (AZs), and Edge Locations; and the Shared Responsibility Model distinguishing 'security of the cloud' (AWS) from 'security in the cloud' (customer). The author highlights benefits such as converting capital expenses to variable costs, economies of scale, and scalable capacity, and notes they will continue to Module 2 to learn about Compute and spinning up virtual servers.
