Cloud computing is the delivery of computing services over the internet. It offers faster innovation, flexible resources, and economies of scale. It is a modern topic often tested in technical exams.
1. Cloud Service Models
There are three main service models in cloud computing:
- IaaS (Infrastructure as a Service): Provides virtualized computing resources over the internet. You rent IT infrastructure (servers, VMs, storage, networks) on a pay-as-you-go basis. Example: AWS EC2, Google Compute Engine.
- PaaS (Platform as a Service): Provides an on-demand environment for developing, testing, delivering, and managing software applications. It abstracts the underlying infrastructure. Example: Heroku, Google App Engine.
- SaaS (Software as a Service): Delivers software applications over the internet, on demand and typically on a subscription basis. Example: Google Workspace, Salesforce, Microsoft 365.
2. Cloud Deployment Models
- Public Cloud: Owned and operated by a third-party cloud service provider (e.g., AWS, Azure). Resources are shared among multiple tenants.
- Private Cloud: Used exclusively by a single business or organization. Can be located on-site or hosted by a third party.
- Hybrid Cloud: Combines public and private clouds, allowing data and applications to be shared between them.
Final Thoughts
