DESCRIPTION
Today competition and profitability exigences lead companies to extend their activity to new markets and new geographical zones. This implies for them a constant need to adapt their organisation and structure to those extensions, including the IT infrastructure. For network administrators, it means that they must have complete control over their network infrastructure in order to be able to deploy their architecture, create new subnets and integrate new organisation models efficiently and in a short period of time to match company’s fast development.

“Why leveraging DNS/DHCP services management at the architecture level can significantly reduce operational costs and ensure business continuity.”
Why do we need to better manage Core Network Services ?
DNS-DHCP and IPAM are critical services to ensure network and application access

What are the issues today as seen by Network Administrators
Typical Core Network InfrastructuresWindows Based
ISC BindCisco
Typical Issues
No guaranteed deployment of DNS/DHCP updates.Unstable Infrastructure Limited reporting and auditing capability.Limited diagnostic capability.No ability to Track changes in IP PlanIPv6 Management

Typical Methodology Today
Changing Administration Approach
Classic modelEach server is individually configuredEach Server is individually managedNo embedded global architecture concept
Complexity of architecture deploymentHigh risks of misconfigurationNo Embedded Best Practices
Difficult and risky architecture modification
4
Classic ModelServer per server administration
How can I reduce my costs…
Less Management Overhead
Faster resolution to critical issues
Empower users to make the right decisions with information and choices
Delegate Non Critical network changes to Junior Admin Staff freeing up valuable resource
Provisioning and automating the underlying tasks needed to deliver services
Simplification of the Core Services management process
Leveraging your existing infrastructure

Smart ArchitecturesConcept
• Central point of administration:configuration and administration of a bunch of serversas a single entity.
• Zero configuration : configuration automatically deployed according the kind of architecture selected
• Architectures templates
• Predefined configurations
• Automatic configurations
• Integrates the “Best Practices”
• SmartArchitectures can be deployedwith multi-vendors DNS-DHCP servers

Smart ArchitecturesSmart DHCP
• Active/active failover
• Star failover
• 80/20 split “Microsoft”

Smart ArchitecturesSome real life’s scenarii
• Changing the Master server after a machine crash
• If a spare machine is available: the Smart Architecture will automatically re-push the configuration to the new machine
• If no spare available : reelection of a new master, with automatic reconfiguration of all the zones with the correct NSand zone-transfers statements
• Enhancing a master/slave architecture
• Add some slave servers to the Smart Architecture
• The new members will automatically be populated: no need to manually create zones and configuration

Smart ArchitecturesSome real life’s scenarii
• Crash of a single Microsoft DHCP
• Once a new server has been installed,the Smart Architecture will automatically push the configuration
• Ensures a hot-backup of any standalone Microsoft DHCP server
