Head in the Clouds • What is a cloud? Ø “Computing capability that provides an abstraction between computing resource and its underlying technical architecture (e. g. servers, storage, networks)” • Five essential characteristics: • On-demand self-service • Broad network access • Resource pooling • Rapid elasticity • Measured service

Head in the Clouds • Public clouds… Ø “Services offered over the public Internet and available to anyone who wants to purchase the service. ” • Private clouds… Ø “Private cloud-virtualized cloud data centers inside your company’s firewall. It may also be a private space dedicated to your company within a cloud provider’s data center. An internal cloud behind the organization’s firewall. ” • Iaa. S – Infrastructure as a service • Paa.

Staying Agile • Planning and managing development of complex software in a waterfall-style project oriented fashion is risky • Scrum is based on iterative development • Key concepts in the Scrum process: • Roles: customer, product owner, dev team, scrum master • Product backlog, release backlog, sprint backlog • Epics, enabling specifications, product backlog items (PBIs) • Iterative development in “sprints” • Definition of Done • Estimation poker, burn-down
