On 18 January 2023, I completed a foundational series of AWS courses on Coursera, aimed at building core knowledge of Amazon Web Services and modern cloud computing practices. While designed for beginners, the content offered a solid introduction to essential cloud concepts, architecture, and services, as well as practical applications in real-world scenarios.
The learning journey began with "AWS Cloud Technical Essentials", which provided a broad overview of the AWS ecosystem. I was introduced to key services such as EC2, S3, RDS, and IAM, and learned how they interconnect to form scalable, secure, and cost-efficient cloud solutions. This course also emphasized navigating the AWS Management Console and understanding the shared responsibility model.
Next, "AWS Fundamentals: Addressing Security Risk" focused on cloud security best practices. It deepened my understanding of identity and access management, encryption, compliance, and monitoring. Through real-world scenarios, I learned how to use AWS tools like IAM policies, AWS Key Management Service (KMS), and AWS CloudTrail to secure cloud environments.
"AWS Fundamentals: Migrating to the Cloud" covered the strategies, phases, and tools involved in moving applications and workloads from on-premises infrastructure to the cloud. I explored services such as AWS Migration Hub, Database Migration Service (DMS), and the AWS Snow Family, learning how to plan, assess, and execute cloud migration projects effectively.
Finally, "AWS Fundamentals: Building Serverless Applications" introduced me to serverless computing, a paradigm that enables developers to focus on code without managing infrastructure. I built hands-on familiarity with services like AWS Lambda, API Gateway, DynamoDB, and Step Functionsâunderstanding how they can be orchestrated to create scalable, event-driven applications.
