VIRTUALISATION WITH LOGICAL SYSTEMS LSYS 1 LSYS 2 LSYS 3 LSYS 4 LSYS 0 (VPLS DOMAIN) SRX ROOT LSYS Key Takeaways Maximum of 32 LSYS Uses an internal switch (VPLS domain) for communication between LSYS Important to minimise inter-lsys flows Inter-LSYS flows processed three times by ingress LSYS, VPLS domain, and egress LSYS Performance implications License-based no LSYS supported with standard SKUs Primary use cases Multi-tenant cloud/dc environments Departmental/Business Unit resource preservation (eg University deployment) Firewall physical consolidation 8 Copyright 2012 Juniper Networks, Inc. www.juniper.net

LSYS RESOURCE PROFILES JUNOS LSYS PROFILE PARAMETERS Firewall Policy Rules Zones Sessions IDP (Enable/Disable) NAT rules Addresses Applications (Services) CPU Utilization Log Rate Resource profiles defined and applied by global administrator Resource profiles broadly cover two parameter categories:- Configuration options, eg firewall policies, zones, NAT rules Compute resources, eg CPU cycles, concurrent sessions, log rates 9 Copyright 2012 Juniper Networks, Inc. www.juniper.net

VIRTUALISATION WITH VRS/ZONES Zone Untrust A Zone Untrust B Zone Untrust C SRX VR A VR B VR C Key Takeaways Much greater scaling than LSYS 2,000 zones/vrs on SRX5800 No license required Generally simpler configuration Requires inter-vr routing not generally possible with static routes Primary use cases Firewall consolidation Service separation Zone Trust A Zone Trust B Zone Trust C 10 Copyright 2012 Juniper Networks, Inc. www.juniper.net

VGW INTEGRATION WITH VCLOUD DIRECTOR vcloud Director 1.5 and vgw Series products can be used together! 1. vcloud relies on traditional vsphere technologies (vcenter & ESX/ESXi hosts). vgw can be inserted into this environment (VMsafe and VI API s are still working and available) 2. vcloud introduces new abstraction constructs which are inserted into vcenter. vcloud API s and vgw API s can be used to discover the constructs and auto-populate SmartGroups for dynamic, human-readable security policies. VM created with semi-random structure. For example: 1 2 vcloud Director Juniper s vcdsync Script uses vcd API s to determine which organizational unit a VM belongs (VMs with same name could be in two different organizational units). VMware vcenter 4 3 vgw management knows that AML- SYS1 is part of Org2. This is made available as a vf.tag Smart Group parameter ESX/ESXi Host with vgw vgw Management inserts AML- SYS1 into SmartGroup and enforces policy on ESX/ESXi host automatically! vgw Management 27 Copyright 2012 Juniper Networks, Inc. www.juniper.net
