The radical shift towards DevOps and the continuous everything movement have changed how organizations develop and deploy software. As the consolidation and standardization of continuous integration and continuous delivery (CI/CD) processes and tools occur in the enterprise, a standardized DevOps model helps organizations deliver faster software functionality at a large scale. However, newer cyber threats, evolving regulatory requirements, and the need to protect brand reputation are putting tremendous pressure on IT leaders to effectively protect their customer and business-critical data.
Conceptually, DevOps pipeline approach makes a lot of sense, however, in practice, Site Reliability Engineering (SRE) and Ops teams optimize systems for service reliability and robustness at the cost of delivering new features. The need for software reliability inherently decreases Continuous Delivery (CD) throughput. This conundrum is the biggest challenge for any organization adopting DevOps practices at a large scale today. By integrating and extending CI/CD with Continuous Resilience (CR) to provide protection against multitudes of software reliability disruptions, DevOps teams can confidently deploy new software and not affect resiliency of the systems. In other words, Continuous Resilience is the radical new enabler that gives confidence for Continue reading

Last month, ICT ministers across Asia-Pacific got together in Singapore to decide on the direction of ICT development in the region. At the end of the three-day gathering, leaders adopted the Singapore Statement of the Asia-Pacific ICT Ministers on Co-creating a Connected Digital Future in the Asia-Pacific, a set of high-level policy guidelines that will set the tone for activities of the Asia-Pacific Telecommunity (APT) in the next five years.
The Singapore Statement is significant in that it fortifies the principles that underpin a conducive environment for the digital economy to thrive:
It is particularly encouraging to see that amidst the race to capitalize on the vast amounts of data collected from us and our online activities, ICT Ministers opted to focus on trust – built on accountability, transparency, and ethics – as a fundamental pillar in the Continue reading
In part 1 of this series, we looked at operators overall, and what they do in OpenShift/Kubernetes. We peeked at the Operator SDK, and why you'd want to use an Ansible Operator rather than other kinds of operators provided by the SDK. We also explored how Ansible Operators are structured and the relevant files created by the Operator SDK when building Kubernetes Operators with Ansible.
In this the second part of this deep dive series, we'll:
We start by creating a new project in OpenShift, which we'll simply call test:
$ oc new-project test --display-name="Testing Ansible Operator" Now using project "test" on server "https://ec2-xx-yy-zz-1.us-east-2.compute.amazonaws.com:8443".
We won't delve too much into this role, however the basic operation is:
TRex is stateful and stateless traffic generator that is designed to benchmark platforms using realistic application traffic. It can generate L3-7 traffic and scale up to 20Gbps. TRex implements the both client and server side. The tutorial provides exact steps that you can follow to install TRex on Ubuntu Server 18.04. Hope you find it useful.
1. Preparing Qemu Ubuntu Server VM for TRex Installation
I assume that you have installed Ubuntu Server 18.0.4 on Qemu disk. Start Qemu Ubuntu Server VM.
$ /usr/local/bin/qemu-system-x86_64 -m 4G -enable-kvm Ubuntu18.04-server-TRex2.vmdk -serial telnet:localhost:2222,server,nowait
Assign IP address from the internal Qemu DHCP server to the guest NIC of Ubuntu Server VM.
$ sudo dhclient
IP address is 10.0.2.15/25 and the default gateway is 10.0.2.2. Now you can connect to the Ubuntu Server issuing telnet from the host.
$ telnet localhost 2222
Copy my script trex-vm.sh from the host to Ubuntu Server Qemu VM. The script installs packages required by TRex. It also redirects VM machine output to serial port and configures old-style Ethernet interfaces naming.
$ scp -rv [email protected]:/home/brezular/trx-vm.sh .
Assign execute privileges to the script and run the Continue reading
The vendor first started talking about Connected Security earlier this year. It involves a layered...
Is it a thinktank? A forum? An incubator?
4 years ago VMware launched Future:NET with a simple idea of bringing together some of the brightest minds in networking together for an open and honest conversation about the future direction of networking.
While other networking conferences have been reduced to vendor showcases, Future:NET has banned product pitches in exchange for open debates that foster intellectual conversation among professionals across the industry.
Come join us at Future:NET 2019, a premier networking technology event, where we are bringing together everyone from enterprises, startups, and academics to debate and challenge the status quo. Wizards may predict the future, but you should plan to come and play a key role with interactive sessions and network with your peers.
This year we are continuing the tradition of open conversation on technology shifts, the organizational challenges they bring and asking the question “are we really making things simple?”. Topics range from the emergence of XaaS, integrated operation models (SOCs vs NOCs), and the effect of 5G, LISP, and v6 on networking. Join experts from Microsoft, AWS, Stanford, and more as they drive deep technical discussions on the future of the Continue reading
Check out my latest book co-authored with my colleagues Gilles Chekroun (@twgilles) and Nico Vibert (@nic972) on VMware NSX networking and security in VMware Cloud on AWS. Thank you Tom Gillis (@_tomgillis), Senior Vice President/General Manager, Networking and Security Business Unit for writing the foreword and providing some great insight.
I’ve been very fortunate to have the opportunity to publish my second VMware Press book. My first book was VMware NSX Multi-site Solutions and Cross-vCenter NSX Design: Day 1 Guide. This book was focused very much on NSX on prem and across multiple sites. In my latest book with Gilles and Nico, the focus was on NSX networking and security in the cloud and cloud/hybrid cloud solutions.
You can download the free ebook here:
In this book you’ll learn how VMware Cloud on AWS with NSX networking and security provides a robust cloud/hybrid cloud solution. With VMware Cloud on AWS extending or moving to the cloud is no longer a daunting task. In this book, we discuss use cases and solutions while also providing a detailed walkthrough of Continue reading
This article explores the specific configuration of Cisco ASA when using it to establish a tunnel for Umbrella SIG. The first question many may have is, “What exactly is SIG?” The answer to that is quite simple–SIG is an acronym for Secure Internet Gateway and in the Umbrella implementation it is basically a cloud-delivered firewall. In other words, the common Cisco Umbrella Dashboard can apply a policy to traffic delivered through the service by a tunneled connection to an on-premises network device. Also, in other words, Umbrella isn’t just for DNS.
The first thing to note is that this is very much a simple, stateful, cloud firewall for outbound traffic. Policy can be applied to one or more tunnels and a tunnel represents a connection back to a device. So this is a way that a network administrator can apply and maintain outbound policy across a large distributed network with very little ongoing effort in terms of changes. The current iteration of Umbrella SIG is outbound only. If the requirements include public-facing services, there is still a need for doing that in a traditional way using traditional mechanism (NAT, ACL, etc) alongside this configuration.
I started Continue reading
