Introduction
Cloud computing has evolved from a convenient hosting solution into the backbone of modern digital infrastructure. Today, businesses of every size rely on cloud platforms to deliver applications, store data, analyze information, and scale services globally. Major providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) have transformed how organizations build and manage their IT environments. Instead of purchasing expensive physical servers, companies can provision virtual infrastructure within minutes and pay only for the resources they use. As technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and edge computing continue to grow, cloud computing is entering a new era. Understanding these changes is essential for System Administrators, Network Engineers, Cloud Engineers, and Cybersecurity professionals.
What is Cloud Computing?
Cloud computing is the delivery of computing resourcesâincluding servers, storage, databases, networking, software, and analyticsâover the internet. Rather than maintaining physical hardware on-site, organizations use cloud services provided by specialized vendors. Cloud services are generally divided into three primary models:
Service Models
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Major Cloud Providers
Amazon Web Services (AWS)
AWS offers services like EC2, S3, Lambda, VPC, and RDS.
Microsoft Azure
Azure integrates well with Windows Server, Microsoft 365, and Active Directory.
Google Cloud Platform
Google Cloud is known for Kubernetes, BigQuery, and AI services.
