The 5 Biggest Mistakes in SD-WAN Security
Simply committing to SD-WAN security isn't enough. It's also necessary to create defenses the right way and avoid some common mistakes.

Success in multi-cloud environments will be characterized by the adoption of an operational framework that can exploit all the advantages of a multi-cloud world.
AnsibleFest is fast approaching! We couldn’t be more excited to be holding our 13th AnsibleFest in Austin, TX. This year's AnsibleFest is on track to be the biggest one ever. Ansible is the proverbial Swiss Army knife in the office desk drawer. The Ansible Integrations track will highlight the combined power of Ansible when used with other technologies. Combining Ansible with other technologies enables organizations to reach new heights with their automation.
As someone who has worked in the DevOps space for years, I'm looking forward to this track. It's filled with talks from speakers that have improved their existing tooling with Ansible. There are a few sessions you might find me standing in the back of (time permitting, of course) that I’d like to highlight here:
1. Ansible and HashiCorp: Better together from Sean Carolan, HashiCorp and Dylan Silva, Red Hat
Automation tools don’t have to be competitive. Great things can be achieved when you combine great tools together and collaborate. Come along and learn how Ansible users can leverage HashiCorp tools/products to achieve their goals of an automated enterprise through complimentary security, image management, post provisioning configuration and integrated end-to-end automation solutions. Read more here.
Having used Ansible Continue reading
The lines between the CPU, its main memory, the memory of accelerators, and various external storage class memories have been blurring for years, and the smudging and smearing is no more pronounced than with IBM’s Power9 family of server processors. …

The previous article discusses an installation of Openswitch OPX on VirtualBox using lvm tool. We have extracted Openswitch OPX VDI disk from VirtualBoxVM and run the disk with Qemu. The image has been subsequently customized using the after install script in order to run it inside GNS3. Finally, we have tested the image within a simple GNS3 lab that proves its functionality. This article goes further and we are going to test VLANs bridging using Linux native commands.

Picture 1 - Network Topology
The lab consists of three Openswitch OPX 2.3.2 instances powered by Qemu hypervisor. The device OPX-Distrib1 is multilayer switch that is responsible for routing between VLANs 10,20,30,40 and 50. The VLANs 10-40 are end-users VLANs and the VLAN50 is used for management. The switches OPX-Access1 and OPX-Access2 are L2 switches with the port e101-001-0 configured as the trunk ports. End users are connected to the access ports e101-002-0 and e101-003-0 on both access switches.
Note: Customized Openswitch OPX 2.3.3 vdi disk can be downloaded in Download section. Login name is opxUser and the password is not set.

Last week, we wrote about implementing ESI with Cloudflare Workers. This is a guest post by Lukas Reider on how to use ESI not only for better performance, but to optimize availability while migrating backends.
In this post, you will learn about how my client Titel Media was able to use Cloudflare Workers to implement simple edge side includes.
The idea is to partially replace the parts of the online magazine highsnobiety.com with a new, and much more refined frontend implementation. In this article, you will get to know the use case, and how I found a powerful application for Cloudflare Workers.
My current project, highsnobiety.com is in the process of replacing Wordpress with a dedicated content pipeline and a custom frontend. It is a huge magazine, with tons of contents, hundreds of daily updates and an international team of more than 60 editors, researching and writing exciting stories.
The company behind it, Titel Media GmbH, a publishing house with offices in Berlin, and New York, surely has grown out of Wordpress for hosting their content.
One does not simply rewrite a sophisticated web publishing pipeline like WordPress. Nor does one, simply Continue reading
A Synergy Research Group report found that Google, Microsoft, Amazon, Apple, and Facebook accounted for 70 percent of total hyperscale capex.
The software-as-a-service (SaaS) platform recreates common Docker container failures across three categories: resource, network, and state.
Networking professionals no longer can only have a limited scope of skills. The addition of other certifications will mean more career growth and more pay.
It is intuitively obvious that most enterprises are want to embrace the public cloud, and they do not want to have a sole source of their cloudy compute, storage, and networking. …

The Internet Engineering Task Force has reached a significant milestone in the process of evolving its own administrative structure to best suit the current requirements of its work. After nearly two years of discussion about various options, the IETF community has created the IETF Administrative LLC (IETF LLC), a new legal entity. Both the Internet Society’s CEO & President Kathy Brown and the Internet Society’s Board of Trustees Chair Gonzalo Camarillo have expressed strong support for the process that has led to this point, and for the direction the IETF has decided to take. Continuing its long-standing positions, the Internet Society also made financial commitments to support the process, and to the IETF going forward.
All of us at the Internet Society who work closely with the IETF believe this new administrative structure strengthens the the foundation for an Internet built on open standards. The new structure will not change any aspect of the IETF’s technical work or the Internet standards process, and clarifies the relationship between ISOC and the IETF. Importantly, the IETF and ISOC continue to be strongly aligned on key principles. ISOC initiatives related to the IETF, such as the Technical Fellows to the IETF and the Continue reading
