Understanding the Cloud
The cloud is often perceived as a magical solution for developers, but its operation is grounded in underlying principles that can improve user experience if understood. While public cloud services like AWS and Google Cloud create complex abstractions, the essence of these services stems from traditional server management. For instance, modern cloud functions like AWS Lambda can seem opaque, but they essentially automate the management of virtual machines and resources. A deeper comprehension of these mechanics enables developers to innovate and design better features that leverage the cloud's full potential.
