Cloud computing is one of the most significant shifts in the IT industry. Instead of investing in physical infrastructure, organizations now use cloud platforms such as AWS, Azure, and Google Cloud to run their applications and services. Each platform offers compute resources, storage solutions, networking, identity management, security services, and AI capabilities.

AWS is known for its extensive ecosystem and global presence, making it a popular choice for startups and enterprises alike. Azure, closely tied to Microsoft products, is often preferred by organizations already using Windows Server, Active Directory, and Office 365. Google Cloud is widely used in AI, machine learning, big data, and container-native workloads.

A cloud computing career typically begins with learning core services: EC2/VMs, VPC networking, object storage, RDS/managed databases, and IAM security. From there, professionals specialize in areas such as cloud architecture, DevOps automation, security engineering, or data engineering. The demand for cloud professionals continues to grow as companies migrate legacy applications to the cloud for scalability and cost efficiency.
