Cloud computing is now the default way to deliver software and service-focused applications. Popular platforms such as Microsoft 365 (rebranded from Office 365 in 2020), Salesforce, Zoom, Microsoft Teams, and Google Meet demonstrate how modern productivity and collaboration tools can be accessed directly through a web browser or installed as Progressive Web Apps—without the need for traditional desktop installations.
Beyond end-user applications, cloud computing also powers complex service ecosystems. A travel company, for instance, might combine independent services for flights, accommodation, and payments into a unified booking platform. This approach reflects the principle of loosely coupled services, which remains important. However, many organizations increasingly rely on serverless computing (such as AWS Lambda and Azure Functions) and AI-driven auto-scaling, reducing the manual overhead of breaking systems into microservices and managing infrastructure.
In general, cloud-hosted services today are:
- Cost efficient – businesses pay only for what they use, avoiding heavy upfront IT investment.
- Scalable and intelligent – modern platforms can scale dynamically with demand, often using AI to optimize resource allocation automatically.
- Accessible – services run seamlessly across browsers, mobile devices, and installed apps via PWAs.
- Compatible – designed to integrate with a wide range of platforms, frameworks, and devices, supporting hybrid and multi-cloud environments.
