Introduction to Cloud Computing By NareshIT
- 1. Introduction to Cloud Computing Cloud computing delivers computing services over the internet. It enables faster innovation, flexible resources, and economies of scale. www.nareshit.com
- 2. Key Characteristics of Cloud Computing On-Demand Self-Service Users provision computing resources automatically without human interaction. Broad Network Access Services are accessible over the network via standard mechanisms. Resource Pooling Provider resources are pooled to serve multiple consumers efficiently. Rapid Elasticity Resources scale quickly outward and inward based on demand. Measured Service Resource usage is monitored and reported for transparency. www.nareshit.com
- 3. Types of Cloud Services Infrastructure as a Service (IaaS) Virtualized computing resources like servers and storage rented online. Example: AWS EC2 Platform as a Service (PaaS) Tools for developing and managing applications without infrastructure worries. Example: Google App Engine Software as a Service (SaaS) Software accessed online on a subscription basis, no installation needed. Example: Microsoft Office 365 www.nareshit.com
- 4. Cloud Deployment Models Overview Public Cloud Shared services over the internet, cost-effective and scalable. Private Cloud Dedicated infrastructure offering enhanced control and security. Hybrid Cloud Combines public and private clouds for flexibility and optimization. Multi-Cloud Uses multiple providers to avoid vendor lock-in and increase resilience.
- 5. Public Cloud Details Public clouds are cost-effective and scalable. Ideal for variable workloads. However, shared infrastructure may not suit sensitive data needs. www.nareshit.com
- 6. Private Cloud Details Private clouds offer enhanced security and control for strict compliance. They involve higher costs and maintenance responsibilities. www.nareshit.com
- 7. Hybrid Cloud Benefits Hybrid clouds balance security and scalability by combining private and public clouds. This model optimizes infrastructure and resource use.
- 8. Multi-Cloud Strategy Multi-cloud avoids dependency on one provider, enhancing resilience. Managing multiple providers increases complexity but improves flexibility. www.nareshit.com
