Romain Decker has an “under the hood” look at the VMware NSX load balancer. Servers/Hardware. This graphical summary of the AWS Application Load Balancer (ALB) is pretty handy. Abdullah Abdullah shares some thoughts on design decisions regarding NSX VXLAN control plane replication modes. Virtualization.

Here’s a quick look at using Envoy as a load balancer in Kubernetes. Servers/Hardware. Via Alex Mitelman’s Systems Design Weekly 015 , I was pointed to this AWS article on multi-site active-active architectures. It’s a good starting point for thinking about operating your own active-active architecture.

Servers/Hardware. This is an interesting deep dive into Intel’s “Ice Lake” Xeon SP architecture. Rudi Martinsen has an article on changing the Avi load balancer license tier (this is in the context of using it with vSphere with Tanzu). I thought it was useful, so now I’m sharing it with you.

If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. Servers/Hardware. Rackspace and VMware have a pair of articles discussing their interoperable OpenStack cloud architecture ( here’s the post from Rackspace , and here’s the post from VMware ). Virtualization.

Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture). Note that there are trade-offs as a result.)

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. What about virtualized load balancers? What about NX-OS, JUNOS, or EOS?

Servers/Hardware. This is an awesome overview of the OpenStack Folsom architecture , courtesy of Ken Pepple. In any case, this article by Frank Denneman on Storage DRS load balancing frequency might be useful to you. There’s a lot to digest there (for me, anyway, there is a lot to digest).

HPs BladeSystem Matrix architecture is based on VirtualConnect infrastructure, and bundled with a suite of mostly existing HP software (Insight Dynamics - VSE, Orchestration, Recovery, Virtual Connect Enterprise Manager) which itself consists of about 21 individual products. But how revolutionary and simplifying are they?

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). Recep talks about how the predominant architecture for network virtualization involves the use of overlay networks created and managed at the edge by virtual switches in the hypervisors. So how does this work?

Whether it is redundant hardware or a private hot-site, keeping an environment up and running 99.99% (insert more 9’s here) of the time is a tough job. With a well-planned deployment, and a good infrastructure, companies can efficiently load-balance their IT environment between multiple active, cloud-based, sites.

Once again this comes back to Intel’s rack-scale architecture work.) A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB).

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware. Servers/Hardware. I needed to fill in some other knowledge gaps first.) Until the 1.3

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.

Building general purpose architectures has always been hard; there are often so many conflicting requirements that you cannot derive an architecture that will serve all, so we have often ended up focusing on one side of the requirements that allow you to serve that area really well. From CPU to GPU. General Purpose GPU programming.

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.), From an architectural perspective, this approach may also be referred to as a compute fabric or Processing Area Network.

The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc. Gartner and others agree - this is the next wave in data center architecture. This permits physically flatter networks.
