When AWS Lambda launched in 2014, it fundamentally changed how we think about infrastructure. No servers to provision, no capacity to plan, no patches to apply—just code that runs when events occur, billed by the millisecond. AWS Lambda Event-Driven Architecture The Mental Model Shift Traditional infrastructure starts with capacity planning: How many servers? What instance […]

Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, as with the electricity grid.
Cloud computing is a natural evolution of the widespread adoption of virtualization, Service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure “in the cloud” that supports them.[1] Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources.[2][3] It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.[4] This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it were a program installed locally on their…
