IT Acquisition, Systems Development, and Cloud Computing

Descripción

IT acquisition, systems development, and cloud computing are core competencies for anyone involved in building or managing business technology. In this course, you'll learn how organizations plan, justify, and acquire information systems, and how they choose between building custom applications and deploying cloud-based solutions. You'll explore cost-benefit approaches like net present value, ROI, and break-even analysis, then examine the strategic decisions behind buying, leasing, or building applications. You'll walk through the traditional systems development life cycle — from feasibility study to implementation and maintenance — and modern alternatives such as agile development, DevOps, and low-code/no-code platforms. You'll then dive into cloud computing: the IaaS, PaaS, and SaaS service models, the public, private, hybrid, and vertical cloud types, and the benefits and risks organizations face when moving to the cloud. You'll compare the "Big Three" cloud vendors — AWS, Microsoft Azure, and Google Cloud — and finish by learning how Web services and service-oriented architecture let systems share data and work together seamlessly.
