Introduction to Cloud Computing
Cloud computing is a technology that enables users to access and store data, applications, and services over the internet instead of on local servers or personal computers. It provides on-demand computing resources such as servers, storage, databases, networking, software, and analytics. Cloud computing allows businesses to scale easily, reduce IT costs, and improve operational efficiency.
Key Characteristics of Cloud Computing
- On-Demand Self-Service – Users can access resources whenever needed without requiring human intervention.
- Broad Network Access – Services are available over the internet and accessible from various devices.
- Resource Pooling – Multiple customers share computing resources, optimizing efficiency.
- Rapid Elasticity – Resources can be scaled up or down dynamically as per demand.
- Measured Service – Cloud usage is metered, and users pay only for what they consume.
Traditional IT Deployment
Before cloud computing, organizations relied on traditional IT deployment, where businesses owned, managed, and maintained their IT infrastructure. This model involved setting up physical servers, networking equipment, and storage within on-premises data centers.
Components of Traditional IT Deployment
- Hardware Infrastructure – Physical servers, networking devices, and storage units.
- Software and Applications – Installed on company-owned servers.
- IT Management – Dedicated teams handle maintenance, updates, and troubleshooting.
- Security and Compliance – Managed by the organization internally.
Challenges of Traditional IT Deployment
- High Initial Costs – Buying and maintaining hardware is expensive.
- Scalability Issues – Scaling requires additional hardware purchases.
- Maintenance Overhead – Regular updates, patches, and security measures are needed.
