vCloud Air Cloud Options and Gateway Choices

CONFIDENTIAL

§  Shared Cloud •  Logically separated network,

compute and storage

§  5GHz CPU (burstable to 10GHz) §  20GB RAM, 2TB storage §  No virtual data center

segmentation §  One Edge Gateway

§  Dedicated Cloud •  Physically separated hosts •  Logically separated network and

storage

vCloud Air Networking Services •  IP Addressing •  Network creation

•  Firewall •  NAT

•  DHCP

•  Load Balancer •  VPN

10

IP Address Assignment •  IP Pool

–  Pool of IPs created by default on auto generated isolated and routed networks

–  Virtual machines attached to those networks get IP addresses from that default pool

•  Static IP –  Fixed IP for a virtual machine –  Change configuration in

VMware® vCloud Director® •  DHCP

–  Part of Edge Gateway service –  Change configuration in vCloud

Director –  Basic DHCP service

Routed Network

11

Firewall Rules in vCloud Air

12

Firewall Rules: North-South and East-West Traffic

Routed Network 1 Routed Network 2 Routed Network 3

Firewall Rules: -  By default: Deny all

-  Policies for traffic that passes through the gateway

Gateway

•  5-tuple firewall policies (Protocol, Source/Dest. IP, Source/Dest. Port )

•  Can have multiple policies across multiple networks

•  Ideal for enterprise grade application deployment

13

Network Address Translation (NAT)

•  Source NAT and Destination NAT rules –  Supports multiple rules on multiple interfaces

•  Can use internal/private IP space –  Bring your own internal IP space –  Create/manage subnets within IP space –  Multiple IP spaces under the same gateway

•  Need to create firewall rules to allow traffic

•  IPv4 NAT

NAT rules: -  SNAT & DNAT rules

-  Options include protocol/port selection

Edge Gateway Services – Load Balancing

Pool Servers

Load Balanced - Round Robin - IP Hash - URI - Least Connected

Virtual Server – - Virtual IP (Public IP) - Frontend traffic - Assigned to a server pool

Can have multiple virtual servers and pools

Edge gateway Load balancer

15

Load Balancer – Pool Servers •  Pool Servers

–  HTTP/HTTPS/TCP –  Load Balancing Methods

•  IP Hash •  Round Robin •  URI •  Least Connected

–  Health Check •  Each with +TCP as mode •  Monitoring Ports

–  Add Servers •  Ratio Weight •  Change Ports/Services per Server

16

Load Balancer – Virtual Servers •  Virtual Servers

–  Apply on outside network –  Server Pool –  Persistence Method

•  HTTP – Cookie •  HTTPS – Session ID

Many Use Cases

19

INTERNET

Connecting to vCloud Air •  Over the Public Internet

–  With Public IPs –  Use NAT for address translation –  By default firewall set to deny all and NAT not configured

INTERNET

•  IPsec VPN –  vCloud Air features include IPSEC VPN –  Multiple VPN tunnels can terminate to Edge Gateway –  Can connect to most of the major on-premises VPN

devices

Application Security – Access Rights •  Administration rights

–  Clearly identify individuals, and rights that the individuals get

–  An enterprise administrator can have more than one type of right

–  Rights help enforce secure cloud usage

•  User rights –  End user rights for virtual

machine owners –  End user cannot do any

admin activity –  Users have limited visibility to

cloud resources
