1.1 Describe the Benefits of VMWare NSX Implementation
· Identify challenges within a physical network interface
-Networking Services still require manual provisioning
-Anchored to vendor specific hardware and topology
Network Provisioning is slow.-The current operational model has resulted slow, manual, error-prone provisioning of network services to support application deployment.
Manual configuration = Mayor complexity and risk, 60% of network downtime and/or security breaches.
IT time to market slow, compute and storage doesn’t move at same speed than networking.
Workload placement and mobility is limited.- The current device-centric approach to networking confines workload to individual physical subnets and availability zones.
Processing the need of availability of compute resources in the datacenter, is very slow, configuration box-to-box.
Will exhaust the limits of configuration.
• VLAN sprawl caused by constantly having to overcome IP addressing and physical topology limitations required to logically group sets of resources
• Firewall rule sprawl resulting from centralized firewalls deployed in increasingly dynamic environments coupled with the common practice of adding new rules but rarely removing any for fear of disrupting service availability;
• Performance choke points and increased network capacity costs due to the need for hair-pinning and multiple hops to route traffic through essential network services that are not pervasively available. The increase of East- West traffic in a data center exacerbates this problem
• Security and network service blind spots that result in choosing to avoid hair-pinning and other deploy risky routing schemes
• Increased complexity in supporting the dynamic nature of today’s cloud data center environments.
NSX key Benefits:
• Network provisioning time reduced from days to seconds.
• Achieve operational efficiency through automation
• Place and move workloads independent of physical topology
• Deploy on any hypervisor and consume through any cloud management platform
• Integrate third-party network and security solutions through standard APIs
• Non-disruptive deployment over existing physical networks or next generation topologies
· Explain common NSX terms
· Describe and differentiate functions and services performed by NSX
NSX key features:
• Logical Switching – Reproduce the complete L2 and L3 switching functionality in a virtual environment, decoupled from underlying hardware
• NSX Gateway – L2 gateway for seamless connection to physical workloads and legacy VLANs
• Logical Routing – Routing between logical switches, providing dynamic routing within different virtual networks.
• Logical Firewall – Distributed firewall, kernel enabled line rate performance, virtualization and identity aware, with activity monitoring
• Logical Load Balancer – Full featured load balancer with SSL termination.
• Logical VPN – Site-to-Site & Remote Access VPN in software
• NSX API – RESTful API for integration into any cloud management platform
