What we have learnt
- Server virtualization is critical for effective resource management in cloud computing.
- Software-Defined Networking (SDN) revolutionizes traditional networking by decoupling control and data planes.
- Network virtualization ensures robust multi-tenancy in cloud environments by providing isolated virtual networks.
Key Concepts
- -- Server Virtualization
- A technology that allows multiple virtual instances to be created on a single physical server to optimize resource usage and improve efficiency.
- -- SoftwareDefined Networking (SDN)
- An approach that separates the control plane from the data plane in networking, allowing for greater programmability and centralized control of network resources.
- -- Network Virtualization
- The creation of logically isolated networks over a shared physical infrastructure, essential for running multiple tenants in cloud environments.
- -- MPLS (Multiprotocol Label Switching)
- A technology that enhances the speed and efficiency of data traffic flow across networks by using labels instead of long network addresses.
- -- VXLAN (Virtual eXtensible LAN)
- A network virtualization technology that encapsulates Layer 2 frames into Layer 3 packets, allowing for scalability and isolation of tenant traffic.
