Cloud Computing
The delivery of computing services including servers, storage, databases, networking, and software over the internet, enabling businesses to use technology without owning physical infrastructure.
In-Depth Explanation
Cloud computing delivers computing resources -- servers, storage, databases, networking, software, analytics, and intelligence -- over the internet ("the cloud"). Instead of owning and maintaining physical data centres and servers, businesses rent access to these resources from cloud providers.
Cloud service models:
- IaaS (Infrastructure as a Service): Virtual machines, storage, networking (AWS EC2, Azure VMs)
- PaaS (Platform as a Service): Development platforms and tools (Heroku, Google App Engine)
- SaaS (Software as a Service): Complete applications (Gmail, Salesforce, Xero)
- FaaS (Functions as a Service): Serverless computing (AWS Lambda, Azure Functions)
Cloud deployment models:
- Public cloud: Shared infrastructure from major providers (AWS, Azure, Google Cloud)
- Private cloud: Dedicated infrastructure for a single organisation
- Hybrid cloud: Mix of public and private cloud environments
- Multi-cloud: Using services from multiple cloud providers
Major cloud providers:
- AWS (Amazon Web Services): Largest market share, broadest services, Sydney region
- Microsoft Azure: Strong for Microsoft ecosystem, Sydney and Melbourne regions
- Google Cloud: Strong in AI/ML and data analytics, Sydney region
- Other: DigitalOcean, Linode, Oracle Cloud
Cloud computing benefits:
- Cost efficiency: Pay for what you use, no upfront hardware investment
- Scalability: Scale resources up or down based on demand
- Reliability: Built-in redundancy and high availability
- Security: Enterprise-grade security managed by specialists
- Global reach: Deploy worldwide with regional data centres
- Innovation speed: Access to cutting-edge services and tools
Business Context
Cloud computing transforms technology from a large capital expense into an operating expense, enabling mid-market businesses to access capabilities that previously required millions in infrastructure investment.
