Cisco Virtual Solutions for VMware ESXi
Cisco Virtual Solutions for VMware ESXi
Virtual Networking is built to create an IP-based network for Virtual Machines. When VMs like VMware need a network to connect to each other or connect to physical equipment, these VMware machines can communicate with each other using Virtual Networking. This virtual network allows virtual machines to connect to virtual networks.
Since VMware machines are located on one host and these VMware must have a network card to connect to the network, the issue of Virtual Switch is raised. On the other hand, we must be careful that I have to consider one network card for each VM. The idea is that we connect one or more NICs to the VS, and we also connect the VMs on the ESXi host to the virtual switch port.
Cisco Virtual Networking
Virtual Networking enables communication between multiple computers, virtual machines (VMs), virtual servers, or other devices across different office and data center locations. Among Cisco virtual products we can mention Cisco NXOS virtual as a virtual switch suitable for Data Center and educational purposes, plus, Cisco CSR1000v and C8000v as a virtual router enabling branch edges to route their WAN and SD-WAN traffic. Also, Cisco C9800v can be deployed in VMware for AP management purposes.
Virtual Networking is a type of virtualization in Cisco networks. This type of virtualization is implemented in the network layer and completely in software. Using this technology and its implementation in enterprise computer networks, capabilities such as switching, routing, firewall, etc. can be implemented without the slightest dependence on hardware and in a completely software and virtual level at the network level. One of the most important preconditions for better Virtual Networking performance is the use of up-to-date licenses for network equipment.
Currently, the services offered under the network virtualization platform are very diverse. Using this technology, you can connect the desired number of routers, switches, etc. according to your needs and with different topologies in the network. The purpose of network virtualization is to get rid of the hardware and the constraints imposed by the hardware on network administrators and users.
Another purpose of using this technology is to be able to connect different main components of the network (routers, switches, etc.) using VMWare. With this approach, network administrators using Cisco-licensed equipment can use VMWare instead of expensive hardware, depending on their needs, which greatly enhances network scalability and security.
Virtual Networking solutions using VMWare license in Cisco networks, network resources such as switches, firewalls, routers, etc. are implemented as logical services in the network, resulting in high speed and flexibility in the data center, increasing efficiency and we will see network security. By virtualizing the network layer, it is possible to divide the network into different virtual parts accurately.
In the cloud and public cloud platform, there will be many limitations if VLANs are used to allocate virtual machines such as VMWare and services to the customer. Because in VLAN we will be able to use up to 4094 addresses and space to be allocated to the customer, if we use VXLAN which is mentioned in network virtualization, we will have about 16 million addresses and space to be allocated to the customer, which is a high figure. In VXLAN or Virtual Extensible LAN, Ethernet frames are packaged and sent in an UDP package.
Cisco Virtual Firewall
For small to medium size companies, Cisco FTDv can be deployed as a VMware virtual machine enabling customers to implement their security policies and considerations into their network. This NGFW, after version 7, supports various tiers based on considered resources leveraging customers to benefit from up to 16 Gbps and 10,000 VPN sessions.
As mentioned, Cisco Firewall can be considered a NGFW. The reason for this is that it can find ways to prevent possible future damage to the network by measuring behavior and learning from what happened in the network. Using Cisco Firewall, which provides VMWare connectivity for users and network administrators, enterprise networks will benefit from multiple layers of security on a single platform. In this way, the cost of purchasing and managing several security solutions in organizations will be saved.
Using multiple devices, if they do not work well together, can cause problems such as increasing the complexity of repairs and finding vulnerabilities in the network. The lack of integrated protection creates several blind spots that intruders use to make organizations vulnerable.
This powerful Cisco equipment is managed through the Cisco Firepower Management Center, which provides a comprehensive view and control over network activity for the corporate security team. This feature includes users, equipment, virtual machine communications, vulnerabilities, threats, client-side applications, files, and websites.
Cisco Virtual Software
As virtualization among organizations grows, more customers are becoming interested in using virtualized applications instead of appliances. So, Cisco has introduced its VMware software as an ultimate solution for enterprises. So now, Cisco ISE, as an access control software, Cisco FMC, as a centralized firewall manager, Cisco Prime Infrastructure, as a monitoring and backup solution, Cisco Stealthwatch, as an advanced NetFlow analyzer can be deployed on the network using VMware hypervisor.
Cisco Collaboration Virtualization
Also, Cisco collaboration software such as Cisco CUCM, CMX and CMM now can be deployed on the VMware vSphere and VMware vCenter.
Note: Currently some applications such as Cisco APIC and Cisco DNA Center cannot operate standalone in the VMware and customers need the appliance as a primary solution and VMware machine can be deployed as a virtual solution.
