I’ve been searching on the Internet for some already builtin Feature Flag Manager for multi-tenant systems, with not much luck. There are some companies and products that offer Feature Flag as a Service (let’s call it like that), which permits managing this contraption for your microservice architecture, but unsure about if they support multi-tenancy.
In this article, I’ll propose a system for a real multi-tenant Feature Flag Manager system. Engage!
I’ve recently started with the training platform from The Linux Foundation, and my first course has been “Containers Fundamentals (LFS253)“. This is the first out of an unknown number of reviews dedicated to the courses I take from The Linux Foundation.

Opening new frontiers. That’s the feeling that I had when the CNCF promoted the opportunity to create new Community Groups across the world. I saw it on Twitter, and I thought, “what if.. ?”. Yes, there it is again, the feeling that comes together with that sentence. After that, I thought, “but it would be pretty hard to manage a Community Group only by myself…”. The rest of the story I will tell on another occasion, but the result of the whole thing is what I want to introduce to all of you today: The Cloud Native Asturias Community Group. Engage!

Deliver a message from point A to point B as fast as possible. This is a requirement for humankind for a long time ago. History says there are records from 900 B.C. about Royal Post system in China to practice communication by written documents carried by an intermediary from one person or place to another. As you can imagine, since then, the way to deliver a message has been changed a lot not only the envelope but also the means of transmission.
Nowadays, in the era of communication between machines, there is still the need of delivering messages, and as fast as possible too. In some cases, you need speed, other cases you prefer to be sure about the reception of the message delivered besides the speed, and you may have many other needs. The systems to deliver messages were called just queue systems, just a couple of decades ago, but today they are frequently called message brokers.
There are several message brokers in the market in the current time. In this post, you will read about NATS. Engage!
Have you ever had the feeling of belonging to a family in your workplace?. What about that sentence “we are not a company, we are a family”?. Maybe, as a leader, you had the feeling that you are failing to your team members because they are not doing what they want all the time. Within your family or your bunch, you do almost what you want to. And here is where the magic question comes. Are you leading a family, a gang of friends, or are you leading a team?
I’d like to share my vision about the important difference between leading as a family or as a team. Engage!
You knew that could happen… it’s part of life and shit happens. Your precious distributed system has been deployed on Monday for the first time in the production environment, with real traffic, brilliant!, all good so far… and on Friday evening, “that” happened. The system starts to raise HTTP 500 status code, just dropping requests like hell, and your dashboards turn from a beautiful green to bloody red. What do you do now?
kubectl scale deployment.v1.apps/my-critial-deployment --replicas=10 #No Jutsu!!That’s a lesson learned: Implement auto-scaling for the Kubernetes deployment by next Monday morning so I don’t have to keep an eye open on the alert system (at least for this).
In this article we will address the Kubernetes auto-scaling feature, how does it work, the complexity of this feature, and some bad practices. Engage!
What a “Senior profile” means? On many of the job offers around LinkedIn and similar, when the recruiters are hiring, we can see the word “Senior” coming close to some sentences like “+5 years of experience on Java”, “+12 years of experience on Windows IIS”, “+7 years as Office Manager in a multicultural company”, “+10 years of experience on System Administrator”, “+2 months peeling potatoes” or even other unbelievable ones.
From that kind of job posts, we could infer that for “the market”, a Senior candidate is the one which spent, at least, some defined period of time working in a certain area. Is this the definition for a Senior profile?. Hence, if you have been working on something for many years you are “at another level” of experience.
Senior, adjetive. – high in rank or status; higher in rank or status than others
Definition from Oxford dictionary
If we focus the conversation into the technology field, does this definition of Senior fit enough with what the companies really want or need?. Engage!.
