The Reasons for VMware NSX

You might think your network is fully virtualized using VMware vSphere. This thinking is somewhat

correct. VMware vSphere allows it to partly. You are using virtual network cards connected to the virtual switch. And all virtual machines can communicate with one host. But that's all for network virtualization.

When your virtual machine is going to talk with another virtual machine, it has a physical machine or the internet. Virtual machine traffic must do this via the UP-Link host (ESXi). From here on, traffic to the physical switch then goes to another ESXi. And virtual machine traffic should not cross multiple hops (Hop, Hub) to reach another virtual machine (for example, a web server). Or rather, a data center on the other side of the

world. Where traffic from physical switches, physical routers, and physical firewalls passes through "all- hardware devices". And VMware uses NSX to provide a chance to move from "hardware devices" to "software networks."

VMware NSX capabilities:

• Network virtualization in Layer 2 and support for tagging of packets (QoS, ACLs) and ...

• Network virtualization in Layer 3 using a router (router) with routing support (north-south) and (east- west)

• The firewall distributed in the closest case to the virtual machines running on the VMware core.

• Software load balancing software

• VPN server to provide VP-N-site-to-site and Remote Access

• The NSX API has the ability to integrate with all kinds of cloud infrastructure.

• Supports a variety of ways, with their integration in NSX.

NSX works well with your current hardware network. So you do not need to buy new hardware. Just like your virtual machines running VMware vSphere. All of your virtual network infrastructure (features listed above) are active on the NSX Hypervisors.

How does VMware NSX work?

How VMware NSX works is awesome, an infrastructure that claims to be able to virtualize all physical network infrastructure. This is a brief look at the VMware NSX architecture:

By encapsulating normal network traffic using encrypted protocols such as STT, VXLAN and GRE, NSX makes it possible to adapt the virtual infrastructure of the network and the physical infrastructure of the network. The physical hardware of the network does not have much to do with virtualization within the capsules, but is compatible with the encapsulation protocols used. And this is the point of communication and compatibility of these two infrastructures.

The NSX Gateway is responsible for the physical and virtual network connection. Each VMware NSX VMware Player runs its own virtual switch (which is a virtual software) and uses it to manage and control its traffic. With the support of VMware NSX, a variety of Hypervisors and cloud management infrastructure, this is a glimpse of its combination with vSphere and vCAC | vCD.
