Physical Network Challenges

• Provisioning is slow• Placement is limited• Mobility is limited• Hardware dependent• Operationally intensive

- Reduce Choke Point Security- Centrally Define Policies, Distribute Rule Enforcement for Segmentation- Security Policies Move with VMs- Changes to central policies automatically distributed to affected VMs

The Power of Distribution – Routing

The Power of Distribution – Firewalling

Service Consumption Using NSX Service Composer

• NSX Service Composer unifies and integrates service consumption across NSX native and 3rd party services

NSX operational model now extended to partner services

Security Challenges: No orchestration between solutions

NSX Service Composer

Security services can now be consumed more efficiently in the software-defined data center.

Apply.

Apply and visualize security policies for

workloads, in one place.

Automate.

Automate workflows across different

services, without custom integration.

Provision.

Provision and monitor uptime of different services, using one

method.
