This episode addresses the security implications of cloud computing, focusing on how responsibilities are shared between provider and customer. Topics include data protection, identity and access man…

This episode explores elasticity and scalability, two defining characteristics of cloud computing. Elasticity refers to the ability to automatically expand or contract resources based on demand, whil…

This episode introduces the concept of multitenancy, where multiple customers share the same cloud infrastructure while maintaining logical separation. Hypervisors, containers, and virtual networks e…

This episode explains how organizations connect securely to cloud environments using Virtual Private Networks (VPNs) and private links. VPNs extend encrypted tunnels over the Internet, providing secu…

This episode introduces Infrastructure as Code (IaC), the practice of managing and provisioning infrastructure through machine-readable configuration files rather than manual processes. Tools like Te…

This episode covers cloud service models, which define how computing resources are delivered. Software as a Service (SaaS) provides complete applications, Infrastructure as a Service (IaaS) delivers …

This episode introduces the four main cloud deployment models: public, private, hybrid, and community. Public clouds provide shared resources over the Internet, private clouds are dedicated to one or…

This episode explains Storage Area Networks (SANs), specialized networks that provide high-speed access to consolidated storage resources. SANs use protocols like Fibre Channel or iSCSI to deliver bl…

This episode introduces network location models, focusing on branch office, on-premises, and colocation deployments. A branch office model connects smaller remote offices back to a central corporate …

This episode explains the concepts of north–south and east–west traffic flow in networks. North–south traffic refers to communication between internal devices and external networks such as the Intern…

This episode introduces spine-and-leaf architecture, a design commonly used in modern data centers. In this model, all leaf switches connect to every spine switch, creating a consistent and predictab…

This episode explores how SDN operates in practice, focusing on the management plane. The management plane is where administrators define network policies, monitor performance, and control behavior t…

This episode explains Software-Defined Networking (SDN), which separates the control plane from the data plane to provide centralized management and programmability. Instead of configuring each devic…

This episode introduces the three-tiered network architecture model, which organizes devices into core, distribution, and access layers. The core provides fast, high-capacity forwarding between distr…

This episode explains Network Time Protocol (NTP), which synchronizes clocks across devices to ensure accurate timestamps and coordinated operations. Accurate timekeeping is essential for authenticat…

This episode examines the Domain Name System (DNS), which translates hostnames into IP addresses. It introduces common record types such as A, AAAA, MX, and CNAME, as well as the process of recursive…

This episode explores Dynamic Host Configuration Protocol (DHCP), which automatically assigns IP addresses and related configuration details to devices. Concepts such as DHCP scopes, reservations, an…

This episode explains the difference between connection-oriented and connectionless communication, two fundamental transport styles. Connection-oriented communication, as seen with TCP, establishes a…

This episode introduces two important tunneling and transport technologies: Generic Routing Encapsulation (GRE) and Internet Protocol Security (IPsec). GRE provides a simple way to encapsulate packet…

This episode focuses on Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), the two primary protocols at the transport layer. TCP is connection-oriented, ensuring reliable delivery …
