Cloud computing

Cloud computing is a model for delivering IT resources—such as servers, storage, databases, networking, software, and analytics—over the internet on demand and with pay-as-you-go pricing. It offers scalability, flexibility, and cost efficiency without the need for physical infrastructure ownership.

• IaaS (Infrastructure as a Service): Provides fundamental computing resources like servers, storage, and networking.

• PaaS (Platform as a Service): Supplies development platforms for building and deploying applications without managing hardware.

• SaaS (Software as a Service): Delivers ready-to-use software applications via the web, such as email, CRM, or ERP systems.

• Public cloud: Shared infrastructure managed by external providers.

• Private cloud: Dedicated infrastructure for one organization, offering greater control.

• Hybrid cloud: Combines private and public resources for flexibility and optimization.

The concept dates back to the 1960s, but “cloud computing” gained widespread use in the early 2000s. Platforms like AWS (2006) and Microsoft Azure (2010) made large-scale cloud adoption possible.

Microsoft Azure represents a leading implementation of cloud computing. It provides IaaS, PaaS, and SaaS capabilities, integrating with Microsoft 365, Dynamics 365, and AI services, emphasizing security, scalability, and global reach.

Cloud computing has transformed IT service delivery, enabling digital transformation through flexibility, automation, and global accessibility.
