Course Objectives • Understand the fundamental concepts of cloud computing and virtualization. • Learn how to design, deploy, and manage cloud computing infrastructure. • Explore various virtualization technologies and understand their advantages and limitations. • Gain an understanding of network virtualization and its benefits. • Learn about cloud computing services and their associated security challenges.

Cloud Computing Overview • Definition of cloud computing: Delivery of on-demand computing resources over the internet • Key features: On-demand self-service, broad network access, resource pooling, rapid elasticity, measured service • Benefits: Cost savings, scalability, flexibility, accessibility, reliability, and security.

Cloud Deployment Models • Public Cloud, Private Cloud, Hybrid Cloud, Community Cloud • Differences between them • Factors to consider when choosing a deployment model • Examples of organizations that use each model

Cloud Service Models • Infrastructure as a Service (IaaS): provides virtualized computing resources over the internet • Platform as a Service (PaaS): provides a platform for developing, testing, and deploying applications over the internet • Software as a Service (SaaS): provides access to software applications over the internet • Storage as a Service (STaaS): provides on-demand storage resources over the internet • Database as a Service (DBaaS): provides on-demand access to database resources over the internet • Security as a Service (SECaaS): provides security services over the internet • Characteristics and Benefits: summarize key features and benefits of each model, provide examples of organizations that use each model

Virtualization Overview • Definition: the process of creating a virtual version of something, such as a server or storage device • Advantages: improved hardware utilization, flexibility, scalability, and cost savings • Types: Server virtualization, network-virtualization, application virtualization, storage virtualization, and desktop-virtualization

Server Virtualization • Definition and Examples: creating multiple virtual servers on a single physical server (VMware, Hyper-V, KVM) • Benefits: increased efficiency, cost savings, improved disaster recovery • Drawbacks: increased complexity, potential performance issues Source : https://www.algiz-technology.com/application-virtualization-for-mobile-devices

Network Virtualization • Definition and Examples: creating a virtual network that is decoupled from the underlying physical network (VMware NSX, Cisco ACI, Juniper Contrail) • Benefits: improved agility, security, and scalability • Drawbacks: increased complexity, potential performance issues

Application Virtualization • Definition and examples of application virtualization, including Citrix Virtual Apps, Microsoft App-V, and VMware ThinApp. • Benefits of improved compatibility, security, and manageability. • Drawbacks of potential performance issues and increased complexity.
