AWS
Providing the compute, storage, and services organisations run their infrastructure on
Amazon Web Services is the world's largest cloud platform by market share, providing over 200 services covering compute, storage, databases, networking, security, machine learning, and developer tooling. Organisations use AWS to host applications, store and process data, run containerised workloads, and build event-driven architectures without owning physical infrastructure. It operates on a pay-as-you-go model with a significant free tier for experimentation. AWS is the most common cloud platform referenced across OccuVista's role corpus, appearing across Cloud and Infrastructure, Data and Analytics, Software Development, and Cybersecurity categories. Working knowledge of core AWS services is expected or preferred in a large proportion of engineering roles in the UK and US markets.
