CIOs Need To Realize That Virtualization Isn't All That It's Cracked Up To Be (a chief information officer needs an IT strategy to create IT alignment)

The Accidental Successful CIO

Kotsovinos points out that a VM is really a collection of interconnected physical subsystems : server, storage, and network. Generally we draw lines between various disciplines based on what they do: the Unix team, the Windows team, the storage guys, the network guys, etc. Sure Virtualization Seems Neat In The Beginning, But….

On Network Virtualization and SDN

Scott Lowe

Is there a difference between network virtualization and Software-Defined Networking (SDN)? So, in a similar fashion to my post on network overlays vs. network virtualization , I thought I’d weigh in with some thoughts. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February.

VMworld 2013 – Network Virtualization: Moving Beyond the Obvious (My Notes)

Virtualized Greek

Speaker: Martin Casado (VMware Networking CTO). NSX is basically a network hypervisor similar to how ESXi is a server hypervisor. So, NSX would sit on top of the physical network, which would give you the same capability to provision extremely complex virtual networks from Layer 2 to 7. Network virtualization allows for more powerful automation. This area allows for high port density implementations to integrate with the virtual network.

DockerCon 2017 Black Belt Session: Cilium for Network and Application Security

Scott Lowe

This is a liveblog of the DockerCon 2017 Black Belt session led by Thomas Graf on Cilium , a new startup that focuses on using eBPF and XDP for network and application security. Graf starts by talking about how BPF (specifically, extended BPF or eBPF) can be used to rethink how the Linux kernel handles network traffic. Why is it necessary to rethink how networking and security is handled? BPF/XDP allows for a 10x improvement in load balancing over IPVS for L3/L4 traffic.

Introduction to Networking: Part 2, A Few More Basics

Scott Lowe

In part 1 of this series, I covered some networking basics (OSI and DoD models; layer 2 vs. layer 3; bridging, switching, and routing; Spanning Tree Protocol; and ARP and flooding). Finally, it’s important to note that VLANs themselves are strictly layer 2 constructs, but because a layer 3 router is needed to pass traffic between them, VLANs are often associated with IP subnets—meaning that each VLAN is considered a unique IP network. Networking VLAN

Dell’s bare metal switch is a big deal for SDN

Virtualized Greek

While Dell isn’t exactly the biggest player in networking, it’s still relevant to note how important their announcement of a bare metal switch is to Software Defined Networking (SDN). The Dell announcement helps bring to reality some of the advantages from a physical network perspective. These hosts can be physical servers, firewalls or load balancers. What if you wanted to manage the entire application environment as a single virtual network?

Looking back at 10 years of compartmentalization at AWS

All Things Distributed

Even though the network design for each data center is massively redundant, interruptions can still occur. No two zones are allowed to share low-level core dependencies, such as power supply or a core network. By using zones, and failover mechanisms such as Elastic IP addresses and Elastic Load Balancing, you can provision your infrastructure with redundancy in mind. At AWS, we don't mark many anniversaries.

Step-by-Step: Setup Multiple Public IPs on a VM in Azure

Assigning multiple IP addresses to a VM enables the you to have multiple websites or services with different IP addresses and SSL certificates on a single server and to use the server as a network virtual appliance, such as a firewall or load balancer. The following diagram was generated using the Network Watcher feature described in my last post ). Navigate the portal to the VM and open the “Network Interface” blade and click on the NIC attached to the VM.

The servers are interconnected using a mesh, ToR, or multi-stage Clos network. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB).

Thinking Out Loud: Targeting the Real Problem

Scott Lowe

Clearly there are some real benefits to using OpenFlow in certain use cases (here’s one example ), but that doesn’t mean OpenFlow—especially hop-by-hop OpenFlow, where OpenFlow is involved at every “hop” of the packet forwarding process throughout the network—is the right solution for all environments. OpenFlow, as I understand it, is targeted at modifying/controlling how packet forwarding occurs across the network.

Speaking of Ivan, he pointed out this post with 45 Wireshark challenges to help you improve your network analysis skills.
