Cross-project collaboration is something OpenStack community has embraced for a long time. Common libraries like Oslo reduces the time and effort to build a new service. Another way this manifests is in new OpenStack services getting built using existing services to solve an higher level use-case.

In this talk we are present how the band of projects comprising of Mistral, Tacker, Neutron, Heat, TOSCA-parser and Barbican came together to build an industry leading ETSI NFV Orchestrator that leveraged the best of these projects. Each of these projects brought in critical functionalities needed towards the final product. You will learn how, when strung together, this solution follows the classic Microservices design pattern that the industry is rapidly adopting.

Le Design Sprint est une approche de prototypage d'un service ou business en 2 ou 5 jours qui permet d'avancer vite et de lever des hypothèses sur une idée.
Mickael Ruau's insight:

 

Les avantages du Design Sprint

Pour résumer mon propos d’hier, c’est une démarche packagée inspirée de l’agilité et du Design Thinking qui offre comme avantages :

  • Démarche collective de résolution de problèmes ou de proposition de solutions
  • Résultats rapides sur la poursuite du produit ou le pivot
  • Immersion totale dans le projet de la part de tous les acteurs pour faire connaissance et s’impliquer

re:Work - Changing the change rules at Google

re:Work - Changing the change rules at Google | DEVOPS | Scoop.it
At Google, change is constant. But how we managed and messaged change wasn’t always working. So we developed a simple framework to rethink reorgs and it starts by asking “Do we even need this change?”
Mickael Ruau's insight:

 

But once you decide to make a change, how do you make it stick? When we use this framework, we do three things to “give legs” to change efforts and improve outcomes:

  1. Start with the “why” and “what.” As one of our leaders said, “Change is constant, but this framework allows us to test and clarify strategic business decisions before they are finalized.”
  2. Go slow to go fast. As early as possible, involve employees in creating solutions, rather than just sharing decisions, and you’ll front load the toughest conversations and make it easier to bring everyone along.
  3. Commit to landing, not just launching. Be sure you’re focused on effecting the change, not just announcing it. This will serve you in the long term because for more and more industries, change is constant.

SRE vs. DevOps: competing standards or close friends?

SRE vs. DevOps: competing standards or close friends? | DEVOPS | Scoop.it

DevOps emerged as a culture and a set of practices that aims to reduce the gaps between software development and software operation. However, the DevOps movement does not explicitly define how to succeed in these areas. In this way, DevOps is like an abstract class or interface in programming. It defines the overall behavior of the system, but the implementation details are left up to the author.

SRE, which evolved at Google to meet internal needs in the early 2000s independently of the DevOps movement, happens to embody the philosophies of DevOps, but has a much more prescriptive way of measuring and achieving reliability through engineering and operations work. In other words, SRE prescribes how to succeed in the various DevOps areas. For example, the table below illustrates the five DevOps pillars and the corresponding SRE practices:

Mickael Ruau's insight:
 
DevOps SRE Reduce organization silos Share ownership with developers by using the same tools and techniques across the stack Accept failure as normal Have a formula for balancing accidents and failures against new releases Implement gradual change Encourage moving quickly by reducing costs of failure Leverage tooling & automation Encourages "automating this year's job away" and minimizing manual systems work to focus on efforts that bring long-term value to the system Measure everything Believes that operations is a software problem, and defines prescriptive ways for measuring availability, uptime, outages, toil, etc.

What happened to OpenStack? – ÆVA : online | DEVOPS | Scoop.it

Click h

The project is still quite healthy and is following the usual hype curve: OpenStack is finally mature enough that it’s less interesting to talk about, so it’s understandable that people think something happened.

The folks asking me this question are generally curios and good intentioned, and I think my answer says a lot about my professional background, so even during an interview I indulge in a short ramble.

I know, I know … I should have written about it at the time, but I had other things going on and wasn’t making space in my life to write. So I’ve decided to revisit the topic today. Next time someone asks me, I’ll just point them here

E-Shaped for High-Performance

E-Shaped for High-Performance | DEVOPS | Scoop.it
When it comes to high-performance, some people argue for “I”-shaped people. Others argue for “T”-shaped people. But there is a great argument that the key to high-performance is actually to be an “E”-shaped person. Are you I-shaped, T-shaped, or E-shaped? E-Shaped, Not T-Shaped for High-Performance I is depth, T is breadth, and E executes (Of …
Mickael Ruau's insight:

4-Es: Experience, Expertise, Exploration, and Execution

According to Sarah Davanzo, “E-shaped” people have a combo of 4 Es: 

“’E-Shaped People’ have a combination of ‘4-E’s’: experience and expertise, exploration and execution.   The last two traits – exploration and execution – are really necessary in the current and future economy.”

Note – If you want to work on your ability to execute, Getting Results the Agile Way is a good way to start (It’s the playbook I wish somebody would have given me long ago.)

Is Your CQ (Curiosity Quotient) the Key to Your Future Success?

According to Sarah Davanzo, your CQ matters more than your IQ and EQ:

“Exploration = curiosity. Innovation and creative problem solving is tied to one’s “curiosity quotient” (CQ). In this day and age of constant change (think: Moore’s Law), one’s CQ is more useful than one’s IQ or EQ.”

Side note – Edward de Bono wrote about how exploring ideas is how to have a beautiful mind.

The 5 Traits of Real Agile Leadership

The 5 Traits of Real Agile Leadership | DEVOPS | Scoop.it

1. Selfless

Let’s all learn from Mr. Dunn’s leadership and what it means to give away a personal ego for a larger purpose. Despite making millions in the NFL, Mr. Dunn has chosen to invest his good fortune into others…lifting struggling single parents to new heights. What does it take for each of us to give away our personal egos at work, so we can mentor and grow others to become better than us?

2. Courageous

Imagine the level of courage Mr. Dunn showed in 1993 as he faced the loss of his only parent. His newfound Father figure responsibilities would’ve overwhelmed almost anyone, but not Warrick Dunn. He faced the moment with the courage to move forward, and look at where that took his life journey.

Workplace courage pales in comparison, but it’s still an essential element of real leadership in an organization. Exemplifying courage allows you to create conditions where your teammates can speak freely when it matters most. What challenges do you face at work? Are there certain situations where you feel scared to tell the truth? Courage is your ability to confront those fears directly, so you can lead your organization toward its larger goals on a daily basis.

3. Focused

Great leaders inspire others, but this inspiration is razor-focused on a shared purpose – which is the vision & mission of the organization. One look at Mr. Dunn’s charity website and you’ll feel the purpose that it serves. In your organization, great leaders understand how to translate the vision & mission into a focused set of business objectives that people achieve…not because they have to, but because they WANT to.

4. Humble

Mr. Dunn does not garner the spotlight. He celebrates the continued success of his work by deflecting the praise toward his charity’s Board of Directors (who are also quite inspiring people). This is a profound trait of great leaders; the ability to melt behind the scenes as others are celebrated for their success.

5. Masters of Their Craft

Great leaders bring a deep level of skills, knowledge and experience in an organization. Like Mr. Dunn, real leaders have lived in the arena (and might still play in the arena), and they use their knowledge and experience to thoughtfully mentor and grow others toward their full potential.
