Liebe Clara (*), …

(This is the German version of my Dear Clara (*), …-article I posted some minutes ago)

Ich bin nicht der Techniker-zu-Deiner-Verfügung

…ich bin nicht der Techniker-zu-Deiner-Verfügung, als den Du mich eventuell ansiehst, weil ich unter Umständen einige Informationen teile, vielleicht Dinge weiß, die Dich interessieren oder wir uns gegebenenfalls mal in der Vergangenheit getroffen haben, ein paar Worte miteinander wechselten oder uns gar beim Turniertanzen gemessen haben.

Wenn Du mich also im sozialen Netzwerk Deiner Wahl etwas fragst, dann gibt es kein Universum, in dem Du von mir erwarten kannst, dass ich Dir innerhalb von Minuten, Stunden oder sogar Tagen antworte. Du wirst Deine Antwort bekommen, jedoch nur zu einem Zeitpunkt, an dem es mir auch passt.

Nebenbei (auch wenn es sich vielleicht anders anfühlt): Ich bin nicht sonderlich aktiv in sozialen Netzwerken unterwegs, ich schaue da vielleicht jeden zweiten Tag hinein, habe keinen FB-Messenger installiert, ja ich benutze noch nicht mal die Standard-Apps für das jeweilige Netzwerk auf meinen mobilen Geräten und habe sämtliche Benachrichtigungen dieser Netzwerke abgeschaltet.

Deshalb tue mir bitte einen Gefallen: Erspare mir, von Dir im sozialen Netzwerk Deiner Wahl gestresst zu werden, und das noch nicht mal 48 Stunden nach Deiner Anfrage. Es wird nicht dazu führen, dass ich schneller oder qualitativ hochwertiger antworte, aber es wird definitiv dazu führen, dass Du dir von mir eine Breitseite und eine geharnischter Antwort einfängst. Und wenn Du Pech hast, dann blogge ich sogar darüber und wenn Du ganz viel Pech hast, rutscht mir sogar Dein echter Name raus, Clara. Deshalb: Frage und frage auch nach – Du sollst Deine Antwort auch haben. Erwarte sie aber nicht in Echtzeit oder zeitnah, deshalb frage lieber zeitiger. Erspare mir Deinen Frust und Deinen Stress, sonst bekommst Du das genau so zurück.

Danke Dir, Clara!

Beste Grüße,

Karsten

Dear Clara (*), …

I am not a Technician-at-your-Disposal

(Deutsche Version dieses Beitrags)

…I am not a Technician-at-your-Disposal, even though I am perhaps sharing quite a lot of information, perhaps may have quite a lot of knowledge in regards to things you are interested in and we perhaps met at some time in the past, had a conversation or two or even battled with each other in a ballroom competition.

So, whenever you ask me something in some social network, there is no world in which you would have the right to expect an answer from me within minutes or even days. I WILL answer your question, but at a point of time, when it fits into my life as well.

Additionally, although it might look differently, I am not following social networks very closely. I am looking into them not more often than every second day, I have no FB-messenger or similar software installed, I actually refuse to use the default applications for such networks and I have turned off any notifications from those networks (Twitter, Facebook, etc.).

Therefore, kindly hesitate to stress me in your social network of choice not even 48 hours after your inquiry. It won’t improve my reaction time, it won’t give you a better answer, but it will guarantee you my frustration and a harsh response. So, do me a favor, Clara: Ask me, but ask me in time. Expect an answer and perhaps remind me of that answer (you deserve it), but don’t bug me or lay your stress and frustration on me, since I will answer you in exactly the same way then.

Thank you, Clara!

Truly yours,

Karsten

Life at Cloudibility (XI): Plus 2!

It’s beginning of August – and today two new members of our Cloudibility Team start their journey with us. And, additionally, two others, who joined in July, need to be introduced as well.

Chris

Chris is a very skilled and talented Security Engineer, which is into DevOps approaches and -technologies, such as Ansible, ELK, Grafana, etc., as well. He will allow us to put even more focus on Cloud Security and Security processes. Welcome on board, Chris!

Sven

Sven is an experienced Project Manager, with a lot of knowledge around processes and ITIL. He will be working as DevOps Manager, utilizing his experiences in classical and traditional processes in order to learn from them when setting up agile DevOps processes. It will be a challenge for him, our customers and ourselves in each other projects, since he knows both worlds. We like that and are happy to have him with us!

Pratibha

Pratibha started working for us mid-July. She is DevOps engineer, has experiences around AWS and Azure, as well in automatizing processes and tools. She immediately impresses with her knowledge and open mind. We are glad to have her in our team!

Rahul

Rahul is an experienced Java engineer, who joined us mid-July at the same time as Pratibha. He is currently working in our test department and does very important work for something yet to be announced. We love, how he takes responsibility and learns about new approaches and processes!

Is that all? No!

We will have another four people joining our company in August and beginning of September. We’re so proud of each of them, since they are hand-picked and bright minds, without any exception.

I love that company!

Life at Cloudibility (X): DevOps? They should do it, not us!

logo_cloudibility_rgb_transparent_square_smallThis is, what you have to take care of when trying to establish a DevOps-culture: Many, if not most, people being affected by a DevOps-approach, will agree with it. At least as long as it does not force them to change anything and as long as they can sell it to their customers or supervisors since DevOps is very popular these days and is to be implemented by them, not by themselves.

Just last week, we had such a situation: We are in a short-term project with an enterprise customer. We have been hired by the vendor doing operations for that customer in a somewhat-CloudNative-environment (they run OpenShift on BareMetal-machines).

The end-customer sees a lot of – let’s call it that way – potential in the collaboration with the ops-vendor. Or to put it in clear words: There is no transparency, no knowledge-sharing, no automation, no versioning and no proper mindset in place at the ops-vendors teams. As a result, a lot of the infrastructure is somewhat running, but not even close to the standards, the end-customers expects. Rightfully expects, in my opinion.

This was the situation when Cloudibility experts were hired to analyze and fix errors in the environment, the software, and the collaboration. We proposed an agile DevOps-based interaction- and operations-model to our customer (the ops-vendor) and discussed chances for such a model with the end-customer as well. Both parties appeared to be very in close in their expressed opinions – yes, they all want to switch to a DevOps-approach.

One week later…

One week later, one of the two companies still sticks to that opinion, the other one does not.

The ops-vendor changed his mind since we perhaps were too successful and identified as well as fixed a lot of improvement-opportunities. He simply does not see the need to change his processes (which lead to the situation we came in) and his way of executing anymore, since the fixes are actually working and the customer appears to be satisfied.

DevOps now is to be executed by his customer, he will be participating in this „a little bit“ (quote), but only „as long as it fits into our processes and does not imply ourselves to change our approach“ (another quote). Plus: „We want to keep our internal approaches a secret, the customer does not need to know about them or can even expect us to adjust to his way of interacting – he is the customer, we are <Company-Name ommitted>“ (quote). And: „Don’t forget, we are not even required to have a logging and a monitoring in place, by the terms of the contract that customer signed“ (quote).

What could possibly go wrong with such a mindset?

Frankly, we expected this behavior from this customer, but it is frustrating nonetheless since they offer a CloudNative and Enterprise-ready environment and operations-model to their customers – and simply can not deliver due to having the wrong mindset and approaches, which gets only visible once a customer signed the contract (we have seen this several times with this customer). They execute IT the old-fashioned ways, having SDM (Service Delivery Managers), steep hierarchies and ITIL-processes in place, instead of DevOps-managers, experts, and an agile operations approach.

So, be careful when someone tells you about executing DevOps. Chances are, all they want is to get their backs covered and they will refuse DevOps as soon as it would imply to change something in their own processes and approaches.

Are we stopping to help such customers and to propose modern, lightweight, cost-efficient and adoptable processes and approaches?

Never ever!

And we will – of course! – successfully end our mission in that specific project as well. But it is kind of sad to see a chance for establishing better approaches and better processes pass by just because one of the involved parties does not want to change anything on their side.

Sad from a mindset’s perspective. From a commercial perspective, it is not: We are happily there to help with the next failing project. Again.

At the end of a very busy, exhausting and stressful week, I took out my 5 year old Kindle Paperwhite and decided to read a book. Without disturbances and notifications, without video, color or any other distraction from the only one interesting thing: The book’s content.

As if mother nature is supporting this, today is a very peaceful and quite day. The cats are playing outdoors, the birds are quite silent, my younger son plays some games on his Android phone, the elder one still sleeps and my beautiful girlfriend watches some TV shows on her iPad, wearing her headphones.

So, the world around me is quite silent. I hope, it will remain that way for a while, since I enjoy it.

It’s a peaceful Sunday indeed.

Thank you, life.

DevOps: Just get it started!

DevOps. Just do it!

I hear this quite often:

Yeah, we want to do DevOps. We understand this is a critical thing, it is important for succeeding in our Dev- and Ops-projects. We can’t do without.

But…

…we need to get the whole picture first. We need to have a fully featured DevOps-concept. We need some infrastructure. We need top clarify with our Stakeholders.

You know what?

These are only excuses for not doing DevOps.

The best approach to DevOps is by simply starting it. Forget about that fully featured DevOps-concept to be discussed throughout all hierarchy levels of your organization. Forget about providing the perfect infrastructure. Forget about everything – just start it!

DevOps is a process and a mindset. It is an approach to collaboration, to transparency and to knowledge sharing. Yes, it always can be done better, more aligned, deeper integrated, etc.

But nonetheless: The best way to start doing DevOps is to simply start doing it.

Today.

DevOps: I will never ever set up and maintain my environment by hand again!

Repeat after me:

I will never ever set up and maintain my environment by hand again!

I will never ever set up and maintain my environment by hand again!

I will never ever set up and maintain my environment by hand again!

If you ignore this advice, you might be ending like a lot of projects I’ve seen in the last years: Unmanageable, unstable, unpredictable and basically unreliable.

Use a tool

Ansible_logo.svgIf you ever happen to set up a something in your environment, learn about tools like Ansible and perhaps Terraform first. Provision your machines and VMs with these tools, roll out your environment using these tools and version the scripts in a repository.

Do not, ever, later on, do changes or install updates on your environment by hand! Again, use Ansible or a similar tool, to roll out and install updates and components.

Version things

220px-Git-logo.svgThe key to automatization is using tools like GIT extensively. Every single configuration file, every single automatization script needs to be put under version control. Every iteration, every change, needs to be versioned as well. Get rid of your local script repositories, keep things in a central, safe place. Share the scripts and configurations, and don’t only document them in your ticketing tool!

Do not use SSH

Of course, SSH is used when working with Ansible or other automatization tools. But you, or any of your team members, should not use it. Using SSH to do tasks on a machine is by definition a manual process, something which has to be avoided! So, forget about SSH as a tool for manually managing infrastructures, configurations, and machines. Script your changes, test your changes, roll out your changes or roll them back – all using Ansible (or other similar tools) and version those scripts as well.

Automatization is key, the tool is not

Don’t feel comfortable with Ansible? Not an issue, use Chef or Puppet or any other automatization framework instead! Don’t want to learn about Terraform? Then go the native route using AWS-CLI or Azure-CLI instead. GIT sucks? Use SVN or CVS or Mercurial!

Regardless of the tool: You need to get the right mindset, and you need to get it, before starting any work! It never worked (and never will work) bringing in automatization and tools later on. You simply won’t be able to consolidate all different configurations without any bigger effort. It’s not gonna work!

Be a developer

Yeah, I know. You are not a developer. You are an administrator. You don’t program things. You don’t write nasty code. You are the specialist, the surgeon.

Well, no. You are a fool if you happen to think so.

You need to think like a developer thinks: Laziness over repetition, scripts over manual approaches, versioning over file-share-based storage. A developer – and believe me, I am one these guys – has a very simple approach: Every repetition of any kind of functionality to be implemented, is basically a wast of time.

A developer tries to write specific code only once, he organizes code in libraries for reusability. He refuses to do things a second time if he could reuse existing code or a library.

Adopt this kind of thinking! Express everything in scripts. Version these scripts. Create your own library of scripts and share it with your fellow colleagues!

Stay in control

I get often asked: What and when do I need to automatize? The answer is simple: Everything, anytime. The moment you SSH into a machine and do any kind of change there, you have lost control. Even if you are unsure about a configurational change being the proper solution to an issue, use a script.

Did I say „Even“? Especially then!

Using an automatization framework, you can roll back the change or set up an environment into a well-known state, allowing you to safely perform changes, test the outcomes and understand the consequences. Since you have versioned everything, you can always revert back to the last known version. Since you have everything in a shared, safe place, you can even lose your computer and your notes – and still remain operational.

And, in case it was not clear enough: This holds true for any kind of environment – Bare-Metal, virtualized, cloud, everything in between.

To stay in control, automatize and version. Everything!

And now repeat the headline. Until you live it.

Life at Cloudibility (IX): I will never ever hire that person!

logo_cloudibility_rgb_transparent_square_smallI said this quite often during several projects over the last years – and often directed to persons being „difficult“ with regards to discussing hard, having different opinions, contradicting a Product Owner or an Architect with thoughtful arguments. This is something you will have to accept, even if it is hard to do so. And it is exhausting, it is stressful working with such people on a day-by-day basis.

But, I changed my mind.

Or, to put it differently, I am now in a position where I want to have such characters around me. Here at Cloudibility, we want persons having their own ideas and their own minds, we want them to contradict us and to proove us to be wrong.

We want to have such minds around us. Of course, they will have to stick to our rules of respect and culture, they will need to be compatible with customers and the team. But besides this: Have your own mind, contradict, improve, overtake us!

So, we are looking for the Crazy Ones:

Are you one of them?

Welcome!
