Layer 2 Switching vs Layer 3 Routing
Developers should learn Layer 2 switching when working on network infrastructure, system administration, or cloud computing projects that require understanding of local network communication and performance optimization meets developers should learn layer 3 routing when building or managing distributed systems, cloud infrastructure, or applications that require cross-network communication, such as microservices architectures or iot deployments. Here's our take.
Layer 2 Switching
Developers should learn Layer 2 switching when working on network infrastructure, system administration, or cloud computing projects that require understanding of local network communication and performance optimization
Layer 2 Switching
Nice PickDevelopers should learn Layer 2 switching when working on network infrastructure, system administration, or cloud computing projects that require understanding of local network communication and performance optimization
Pros
- +It is essential for designing and troubleshooting LANs, implementing VLANs for network segmentation, and ensuring reliable data transfer in environments like data centers or office networks
- +Related to: osi-model, mac-address
Cons
- -Specific tradeoffs depend on your use case
Layer 3 Routing
Developers should learn Layer 3 routing when building or managing distributed systems, cloud infrastructure, or applications that require cross-network communication, such as microservices architectures or IoT deployments
Pros
- +It is essential for optimizing network performance, ensuring scalability, and implementing security measures like firewalls and VPNs in complex environments
- +Related to: ip-addressing, routing-protocols
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Layer 2 Switching if: You want it is essential for designing and troubleshooting lans, implementing vlans for network segmentation, and ensuring reliable data transfer in environments like data centers or office networks and can live with specific tradeoffs depend on your use case.
Use Layer 3 Routing if: You prioritize it is essential for optimizing network performance, ensuring scalability, and implementing security measures like firewalls and vpns in complex environments over what Layer 2 Switching offers.
