Along with our Ansible Quick Start course, we have multiple new courses and hands-on labs coming out this week along with an update on an upcoming study group, Understanding Burnout. Using Terraform to Create a Docker Volume and Network. Load Balancing Google Compute Engine Instances. New Releases. Using the Command Line.

News is using a wide variety of AWS services: EC2, S3, VPC, Direct Connect, Route 53, CloudFront, CloudFormation, CloudWatch, RDS, WorkSpaces, Storage Gateway. Elastic Load Balancing left unused. Elastic Block Storage volumes left unattached. Regular review of security groups. No tagging. No right-sizing.

Networking. Open Virtual Network (OVN) is really ramping up and getting lots of attention, which I personally think is absolutely well-deserved. One new networking feature added to OpenStack in the Kilo release was Neutron subnet pools. Jon Langemak has a write-up on network namespaces as well that is worth reading.

” From a network performance perspective, Matrix includes 2x10Gb ‘fabric’ connections, 16x8Gb SAN uplinks, and 16x10Gb Ethernet uplinks. As you would expect, the system has pretty fast networking; Cisco’s system includes 2x10Gb fabric interconnects, 8x4Gb SAN uplink ports, and 8x10Gb Ethernet uplink ports.

Networking. Mustafa Akin has an article on Docker’s new overlay networking functionality. Here’s a post that claims to translate OVS and OpenStack Neutron to the network engineer’s language. I would respond to that by saying OpenStack Neutron wasn’t built to manage a physical network. Now, on to the content!

The Accidental Successful CIO

AUGUST 3, 2011

In the old days, IT departments had developed the tools and processes that they needed in order to deal with building large groups of new servers or handling a planned data center maintenance activity. Kotsovinos points out that a VM is really a collection of interconnected physical subsystems : server, storage, and network.

IO Virtualization is an approach whereby physical IO components such as Network Interface Cards (NICs) Host Bus Adaptors (HBAs) and Keyboard/video/Mouse ports (KVM) are reproduced logically rather than physically. Converged Networking Adapters (e.g. This blog is related to my 2009 installment on Fabric as an IT Enabler. What is IOV?

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). This gave rise to a group of STP versions, such as PVST and the like.). Introduction to Networking: Part 2, A Few More Basics. Link Aggregation.

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.

Four days packed with presentations and networking (of the social kind). Think of it this way: Fabric Computing is the componentization and abstraction of infrastructure (such as CPU, Memory, Network and Storage). Virtual networking. This permits physically flatter networks. Tuesday, December 8, 2009.

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. Burton Group blog.

For IaaS technology, the trunk is built of essential cloud core services: compute, networking and storage. API compatibility provided via a higher-level proxy would allow for the breakout of maintenance to a specific group of engineers focused on that requirement (and remove that burden from the individual service teams).
