Liveblog: Journey to the Cloud with Packer and Terraform
This is a liveblog of the HashiConf 2017 breakout session titled “Journey to the Cloud with Packer and Terraform,” presented by Nadeem Ahmad, a senior software developer at Box.
Ahmad starts with a quick review of Box, but (thankfully) transitions quickly to his particular team at Box (the Productivity Engineering team). His team’s customers are the software developers at Box, and it’s his team’s job to help make them more productive and efficient. One of the tools that Ahmad’s team built was a tool called Cluster Runner, which is intended to streamline running unit and integration tests on the code the developers were writing.
This brings Ahmad to the crux of this presentation, which is telling the story of how Box went from a bare-metal environment to a cloud-based architecture. The purpose of this migration was to address some of the limitations of their bare-metal environment (inelastic, divergent host configurations over time, etc.). Box leveraged Platform9 to build an OpenStack-based private cloud, with the intent of switching to AWS, GCP, or Azure in the future as private cloud resources aged out.
Ahmad next goes into why Box selected the process they did; they wanted to move away from configuration Continue reading
Introducing oVirt 4.2.0 Alpha
On September 28, the oVirt project released version 4.2.0 Alpha, available for Red Hat Enterprise Linux 7.4, CentOS Linux 7.4, or similar.
This pre-release version should not be used in production, and is not feature complete.
oVirt is the open source virtualization solution that provides an awesome KVM management interface for multi-node virtualization. This maintenance version is super stable and there are some nice new features.
what's new in oVirt 4.2.0?
Here's an overview of the new main features:
The Administration Portal has been redesigned from scratch using Patternfly, a widely adopted standard in web application design that promotes consistency and usability across IT applications, through UX patterns and widgets. The result is a cleaner, more intuitive and user-friendly user interface. The old horizontal menu has been replaced by a two-level vertical menu. The system tree is gone, and its functionality has been integrated into the vertical menus. Here are some screenshots:
Dashboard
Virtual Machines View
Adding a New Virtual Machine
Storage View
An all new VM Portal for non-admin users - designed with React-based UI and Patternfly principles - replaces the existing User Portal. Built with performance and ease of use in mind, Continue reading
Recognizing Internet visionaries, innovators, and leaders from around the world
As the Internet Society celebrates 25 years of advocacy for an open, globally-connected, and secure Internet, we are honored to recognize some of the trailblazers who have fueled the Internet’s historic growth.
On September 18, the Internet Society gathered to honor the fourth class of Internet Hall of Fame Inductees at UCLA, where nearly 50 years ago the first message was sent over the Internet’s predecessor, the ARPANET. Over the years, the Internet has evolved thanks to the tireless efforts of individuals, including these inductees, who believed in the potential of an open Internet.
Representing 10 countries, the 14 individuals who comprise the 2017 inductee class are computer scientists, academics, inventors and authors who have advanced the Internet with key technical contributions, fostered its global reach and increased the general public’s understanding of how it works—in turn accelerating global accessibility and usage among us all.
Ultimately, the success of the Internet depends on the people behind it, and these inductees personify the pioneering spirit of the ‘Innovators’ and ‘Global Connectors’ that have been so instrumental in bringing us this unprecedented technology. They are some of the earliest Internet evangelists and their work has been the foundation for so Continue reading

HashiConf 2017 Day 1 Keynote
This is a liveblog from the day 1 keynote (general session) at HashiConf 2017 in Austin, TX. I’m attending HashiConf this year as an “ordinary attendee” (not working or speaking), and so I’m looking forward to being able to actually sit in on sessions for a change.
At 9:43am, the keynote kicks off with someone (I don’t know who, he doesn’t identify himself) who provides some logistics about the event, the Wi-Fi, asking attendees to tweet, etc. After a couple minutes, he brings out Mitchell Hashimoto, Founder and co-CTO of HashiCorp, onto the stage.
Hashimoto starts out his talk by reviewing a bit of the history and growth of both HashiConf (and, indirectly, HashiCorp). Last year, HashiCorp has grown from about 50 employees to now over 130 employees. HashiCorp has also seen significant community growth, Hashimoto says, and he reviews the growth in in the use of HashiCorp’s products (Vagrant, Packer, Terraform, Vault, Consul, and Nomad). Hashimoto also reviews the growth in their commercial products (Consul Enterprise, Vault Enterprise, and Terraform Enterprise). Hashimoto also discusses HashiCorp’s commitment to open source software and the desire to properly balance commercial (paid) products versus free (open source) projects.
Hashimoto now transitions his discussion Continue reading
New Website Features
One of the reasons I migrated this site to Hugo a little over a month ago was that Hugo offered the ability to do things with the site that I couldn’t (easily) do with Jekyll (via GitHub Pages). Over the last few days, I’ve taken advantage of Hugo’s flexibility to add a couple new features to the site.
New functionality that I’ve added includes:
Category- and tag-specific RSS feeds: Hugo can easily generate category- and tag-specific RSS feeds, enabling readers to subscribe to the RSS feed for a particular category or tag. On the taxonomy list pages—these are the pages that list all the posts found in a particular category or tag—there’s now a small link to the RSS feed for that specific category or tag. (As an example, checkout the list of posts in the “General” category.)
(Truly) Related posts: The “Related Posts” section at the bottom of posts has returned, thanks to new functionality found in Hugo 0.27 (functionality that was, apparently, inspired in part by my experiences—see the docs page). This section lists 3 posts that are considered by Hugo to be related, based on the category and tags assigned to the posts.
It’s Continue reading
Improving BGP Convergence without Tweaking BGP Timers
One of the perks of my online courses is the lifetime access to course Slack team, and you’d amazed by the variety of questions asked there. Not so long ago I got one on BGP timers:
The BGP timers I’m using in my network are 5 and 15 seconds, and I am not sure if it's a good practice to reduce them even more.
You should always ask yourself this set of questions before tweaking a nerd knob:

Today I am going to talk about the Network Access Control- NAC and the vendors of the NAC services providers basically Cisco and Aruba. I will talk Aruba's ClearPass and then I will go with the Cisco NAC solution named as Cisco ISE.
As per the market and the Gartner's Magic Quadrant, Cisco ISE is leading the space followed by Fore scout and Aruba Networks. Before we start with the NAC solution, First question you guys expecting is that what is NAC- Network Access Control.
What is NAC- Network Access Control ?
Network access control (NAC) and is also called network admission control, is a method of
strengthen the security of a proprietary network by restricting the availability of network resources to endpoint devices that comply with a defined security policy.
So as per the NAC, the end devices are being authenticated to access the network. Hope you understand the use of the NAC- Network Access Control. While the computer is being checked by a installed software agent, it can only access resources that can remediate any issues. Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined within the Continue reading

Is M8 The Last Hurrah For Oracle Sparc?
Intel is not the only system maker that is looking to converge its processor lines to make life a bit simpler for itself and for its customers as well as to save some money on engineering work. Oracle has just announced its Sparc M8 processor, and while this is an interesting chip, what is also interesting is that a Sparc T8 companion processor aimed at entry and midrange systems was not already introduced and does not appear to be in the works.
There is plenty a little weird here. The new Sparc T8 systems are, in fact, going to be …

What does the future hold for the Internet?
This is the fundamental question that we are posing through the report just launched today, our 2017 Global Internet Report: Paths to Our Digital Future.
The report is a window into the diverse views and perspectives of a global community that cares deeply about how the Internet will evolve and impact humanity over the next 5-7 years. We couldn’t know what we would find when we embarked on the journey to map what stakeholders believe could shape the future of the Internet, nor can we truly know what will happen to the Internet, but we do now have a sense of what we need to think about today to help shape the Internet of tomorrow. The report reflects the views and aspirations of our community as well as some of the most pressing challenges facing the future of this great innovation.
What have we learned? We’ve learned that our community remains confident that the core Internet values that gave rise to the Internet remain valid. We also heard very strong worries that the user-centric model of the Internet is under extraordinary pressure from governments, from technology giants, and even from the technology itself. There is a sense that there Continue reading
