The collision occurred after I read these two blog posts ( here and here ) by Ivan Pepelnjak on manual VLAN provisioning. Based on what I’ve seen and read so far, it seems like a lot of folks see software-defined networking (SDN), especially hop-by-hop OpenFlow, as the solution to manual VLAN provisioning.

Ask some CTO’s about how their product scales and they’ll whip out a logical diagram showing you redundant networks, redundant firewalls, load balancers, clustered application servers, redundant databases, and SAN storage. How are customer specific implementations managed in their software repository?

Is there a difference between network virtualization and Software-Defined Networking (SDN)? One of the topics we discussed on the podcast was the relationship between SDN and network virtualization, which sparked this blog post by Keith Townsend, one of the attendees. These are all software—does that make them SDN?

Eschewing any technical practices, this course takes a high-level view of the history of Linux, the open-source movement, and how this powerful software is used today. Are you a non-technical person just wanting to know what this “Linux” thing is?

As a provider, Expedient has to balance five core resources: compute, storage (capacity), storage (performance), network I/O, and memory. It is, however, very well-suited to workloads that need predictable performance and that work with lots of small packets (firewalls, load balancers, other network devices).

The arrival of virtualization software changed everything. This low level software allowed multiple applications to run on the same physical hardware but believe that they had the box all to themselves. Kotsovinos points out that a VM is really a collection of interconnected physical subsystems : server, storage, and network.

More than one person took note of how I compared its simplicity in contrast to other offerings in the same space, but failed to detail the specifics of Egeneras PAN Manager software and how it mapped to 13 common IT Service Management functions.

This blog is related to my 2009 installment on Fabric as an IT Enabler. In essence, a server’s logical IO is consolidated down to a single (physical) converged network which carries data, storage and KVM traffic. However, to be clear, IOV is not a software layer as-is the hypervisor). What is IOV?

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.

Converged Infrastructure and Unified Computing are both terms referring to technology where the complete server profile, including I/O (NICs, HBAs, KVM), networking (VLANs, IP load balancing, etc.), and storage connectivity (LUN mapping, switch control) are all abstracted and defined/configured in software.

Craig Matsumoto of SDxCentral recently published a piece on NFV performance ; that article was based largely on a blog post by Martin Taylor of Metaswitch found here. The “gotcha” is that these software stacks haven’t been written yet, so the idea of repurposing hardware from switch to firewall to load balancer is still a bit of a unicorn.

Think of it this way: Fabric Computing is the componentization and abstraction of infrastructure (such as CPU, Memory, Network and Storage). This is very much analogous to how OS virtualization componentizes and abstracts OS and application software stacks. Provisioning of the network, VLANs, IP load balancing, etc.

other than managing your software stack). And I mean I/O components like NICs and HBAs, not to mention switches, load balancers and cables. In the same way that the software domain has been virtualized by the hypervisor, the infrastructure world can be virtualized with I/O virtualization and converged networking.

Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well. The different stages were then load balanced across the available units. Also more details can be found on the AWS Developer blog.
