Cloud Computing Tutorial

[certforumz]

Cloud Computing is a transformative technology that delivers computing services—such as servers, storage, databases, networking, software, and analytics—over the internet. This model eliminates the need for physical hardware on-site, allowing businesses and individuals to access resources on demand and pay only for what they use.

Key Characteristics of Cloud Computing:
On-Demand Self-Service: Users can provision resources automatically without human intervention.
Scalability: Resources can be scaled up or down based on demand, ensuring cost efficiency.
Broad Network Access: Services are accessible from anywhere via the internet.
Resource Pooling: Providers use multi-tenancy to serve multiple customers securely.
Measured Service: Usage is tracked, providing transparency and optimization.
Types of Cloud Computing:
Public Cloud: Services offered over the internet to multiple customers (e.g., AWS, Microsoft Azure).
Private Cloud: Dedicated resources for a single organization, offering enhanced security.
Hybrid Cloud: A mix of public and private clouds for flexibility and optimization.
Service Models:
Infrastructure as a Service (IaaS): Virtualized computing resources (e.g., EC2).
Platform as a Service (PaaS): Development environments (e.g., AWS Elastic Beanstalk).
Software as a Service (SaaS): Ready-to-use applications (e.g., Google Workspace).
Cloud computing drives innovation, reduces costs, and enhances agility across industries, making it a cornerstone of modern IT.
