I am getting super excited about my first ever AnsibleFest! Despite using Ansible for more than five years now, I have never had the opportunity to attend this famed event. I had coworkers from previous employers attend, and they were always excited and invigorated after the conference. October is fast approaching and the energy around the event is growing every day.
I’m especially excited for AnsibleFest 2018 because it will have an entire track dedicated to my favorite subject: Network Automation. Join us for two days (October 2-3) as Ansible network developers, Ansible experts from around the world, partners and community members showcase new functionality, use cases, stories and paths to production. You will hear from the developers who design, create, test and distribute the code. You’ll also hear from industry experts and network operators who create and deploy Ansible Playbooks to manage a variety of network gear and situations.
I’ll highlight two talks I’m especially excited about, to give you an idea of what you’ll learn in the Network Automation track at AnsibleFest 2018.
First up is one of my favorite coworkers, Trishna Guha, talking about the Network-Engine role. Trishna will highlight how Network-Engine extracts data from network devices Continue reading
These issues can delay deployments, result in inferior service quality, and make it difficult to reach return on investment goals, according to John Isch at Orange Business Services.

Hey, it's HighScalability time:
Do you like this sort of Stuff? Please lend me your support on Patreon. It would mean a great deal to me. And if you know anyone looking for a simple book that uses lots of pictures and lots of examples to explain the cloud, then please recommend my new book: Explain the Cloud Like I'm 10. They'll love you even more.
Companies can run Array’s security and networking applications, open source applications, or those from third-party vendors like Cisco and F5 on the platform.
This is an adapted transcript of a talk I gave at Promcon 2018. You can find slides with additional information on our Prometheus deployment and presenter notes here. There's also a video.

Here at Cloudflare we use Prometheus to collect operational metrics. We run it on hundreds of servers and ingest millions of metrics per second to get insight into our network and provide the best possible service to our customers.
Prometheus metric format is popular enough, it's now being standardized as OpenMetrics under Cloud Native Computing Foundation. It's exciting to see convergence in long fragmented metrics landscape.
In this blog post we'll talk about how we measure low level metrics and share a tool that can help you to get similar understanding of your systems.
There are two main exporters one can use to get some insight into a Linux system performance.
The first one is node_exporter that gives you information about basics like CPU usage breakdown by type, memory usage, disk IO stats, filesystem and network usage.
The second one is cAdvisor, that gives similar metrics, but drills down to a container level. Instead Continue reading
In this Network Collective Short Take, Russ White examines the relationship between state, optimization, and interaction surfaces when adding complexity to a network or system.

To meet the needs of the emerging applications and networks, the clouds are descending toward the ground and even dispersed among the client devices – forming fog computing and networking or fog. Learn more about fog computing at Fog World Congress 2018.

It’s no surprise that Twitter’s developers are messing around with the platform. Again. This time, it’s the implementation of changes announced back in May. Twitter is finally cutting off access to their API that third party clients have been using for the past few years. They’re forcing these clients to use their new API structure for things like notifications and removing support for streaming. This new API structure also has a hefty price tag. For 250 users it’s almost $3,000/month.
You can imagine the feedback that Twitter has gotten. Users of popular programs like Tweetbot and Twitterific were forced to degrade client functionality thanks to the implementation of these changes. Twitter power users have been voicing their opinions with the hashtag #BreakingMyTwitter. I’m among the people that are frustrated that Twitter is chasing the dollar instead of the users.
Twitter is beholden to a harsh mistress. Wall Street doesn’t care about user interface or API accessibility. They care about money. They care are results and profit. And if you aren’t turning a profit you’re a loser that people will abandon. So Twitter has to make money somehow. And how is Twitter supposed to make money in today’s Continue reading
On International Youth Day, the Internet Society and Global Scribes partnered to connect youth around the world to let their voices be heard, allowing them to become empowered and engaged global citizens, striving toward a more united and sustainable digital future.
As local and international actors innovate to solve the most pressing issues that we face in the world today, young people are often left out of the equation with little or no participation in important discussions and decision-making processes.
Youth across the world are often overlooked as a potential resource to solving global challenges, such as climate change, migration, health, and unemployment, despite being directly impacted by these issues and having opinions on how to solve them.
This also happens in the Internet ecosystem, where young people often do not have a place at the table when it comes to decisions that shape the Internet’s future.
While youth are recognized as “the future generation” and perceived as key to a more sustainable tomorrow, they are seldom given adequate platforms to let their voices be heard or allow them to contribute to their societies in a meaningful way, in their own right as youth.
Young people are often deprived of the opportunity to serve as catalysts for a more united and sustainable world Continue reading
By embracing a different mindset and changing their language, IT teams can better communicate with the business and finally overcome a long-standing division.
