NETWORK TRAFFIC CONTROL USING CUSTOMIZED VMWARE APPLIANCE P.N. Vineeth Kumar Software QA Engineer II Dec/03/2007 AS-11

 Creating specialized virtual appliances and providing a single box solution for complex networks. AIM  Managing such appliances using a GUI or through a ready-to-deploy format.

Packaging ideas along with the product -Possibilities : Virtualization at all layers of the OSI reference model. -Finding possibilities of using VMware technology on each of these layers. -Customer scenarios related to each of them. -Chalking out new areas / methods for increasing the productivity / efficiency of an existing virtualized platform. -Providing simple, yet highly efficient solutions based on virtualization, to solve frequent issues faced by customer. -Feasibility of the solution should be within a chalk point. -Nurturing ideas / solutions for future enhancements on existing platforms for customer satisfaction. -Updating customers with new ideas which are tested and certified, on a routine basis, along with patches, if needed. -And many more

Typical Traffic Flow DMZ

Evils of Existing Networking Techniques

Major Network components / devices  Routers  Switches  Firewalls  Load Balancers  Traffic Splitter

Single Box Solution ESX / VMWARE Server Physical Interfaces Internet / Client Network Internal / Server Layer Splitter / Broker Firewall Load-balancer

Load-balancer failover IPVS Ratio 2:1 x 2 1:1 x 2 Fail- over 1:1 x 2

Proposed Setup VMWAE/ESX Server I/P NICs O/P NICS Fail-over Classic ESX VM MASTER VM Physical Switch Fail-over

Proposed Positives

DMZ on DVD  The entire set of VMs and its configuration data can be put on a single DVD.  The deployment of the solution is only a click away.  The VMs will be generalized and only the configuration data varies between setups.  Configurations can be stored centralized location and can be made accessible to the all the setups of a datacenter.  The VM network within an ESX can be represented as an XML, and hence we can save the network setup in a portable format.  Drag and drop GUI can help is managing the VMs on the virtual network. The configurations needs to be altered automatically.  Configuration data can be generated using a wizard and are stored in portable format (say XML).  The entire network along with it’s configuration can be backed up for restoration process ( worst case scenario), on a set of DVD or any other removable media.  Should be made compatible with upcoming projects of virtualizing networking components (like routers and switches).
