As I stumble upon Spring all the time when reading about state-of-the-art development techniques, I want to understand better what it is. (I mentioned in one of my first articles that I got some homework to do… 🙂 )
I started with watching this youtube-video of 2015 where Josh Long, part of the Pivotal-team, gets some basic information how to get started with Spring Boot development:
The video title is already mentioning Spring Boot, on other places I read about Spring Cloud… I would like to clarify those different aspects in this article. Continue reading “Spring… in July?”
When trying to gain more knowledge about microservices, it’s nearly impossible to get around all the aspects of DevOps. The improvement of the DevOps processes is one of the major advantages for following the microservices philosophy. To get a better understanding about what DevOps really means (and what not), I’d like to collect some information here.
First of all, Wikipedia defines DevOps as follows: Continue reading “Who the fuck is DevOps?”
I would like to use the IoT-challenge and the brewcloud-project as opportunity for getting in touch with iOS-app-development in general (I mentioned my first steps in my last article) and the SAP Cloud Platform SDK for iOS in special.
When digging deeper into this topic, it seems first important to understand what SAP Fiori really is. Obviously, it has something to do with new, modern, mobile-enabled UIs by SAP, but is it a development language, a framework? What’s the exact definition of SAP Fiori? Is it the same as SAPUI5? Continue reading “SAP Cloud Platform SDK for iOS – what is that?”
Ok, I think after writing the last article, I generally understood: The usage of Microservices is good because it makes your IT landscape very flexible. Changing them is easy, testing them is easy, redeploying them takes in best case seconds. If you use them successfully, this advantages help you to deliver new features quickly to your users which nowadays is key in the competition.
When reading further articles about the topic, I found some interesting reports about big tech companies using microservices productively. That’s pretty interesting because reading theoretical books is one thing, but gaining insights and experience reports of real usage is another level of information.
One prominent early adopter of the microservices-approach is Netflix. Originally, this article was supposed to cover several copanies and their IT philosophies. But Netflix has is too interesting to write less than one article about it. Continue reading “Netflix’s army of monkeys”
So the first thing I would like to dig deeper into are microservices.
As I am in touch with some common IT- and tech-magazines and -blogs, I stumbled over that topic again and again, but I never really understood what this hype was all about. Anyhow, it seems that you can’t get around microservices, so I’d like to collect what I figured out about microservices. ( I think one of the earliest famous articles was the one by Martin Fowler: click )
The problem which microservices want to adress is that quite often, the programs in enterprise IT-landscapes are put in one big application. Actually, I have also seen this or some aspects of it in one of the systems I worked with for a long time. Continue reading “microservices – motivation”
(I will write some texts about tech topics and I will write them in English. First, that’s kind of common in the tech world and second, it’s easier to connect with people around the globe if the text is in English.)
Soon, I will change my job and work in a new role within SAP. I will support customers with the SAP Cloud Platform , SAP’s Platform-as-a-Service-offer. One of the most common reasons for using a PaaS is enabling a development environment that is easy to set up and supports you in deploying and running your applications afterwards.
That brings me back to the world of non-SAP-software-development where I have some roots due to my Java history, but I haven’t touched that world too much in the lost couple of years working as SAP-consultant: Continue reading “back in the free world”
Das erste Projekt, von dem ich hier schreiben möchte, ist meine Heizungsautomatisierung.
Zuerst zu unserer Wohnung: Wir wohnen in einer Altbau-Wohnung mit 3,60 Meter hohen Decken, was die Zeit zum Aufheizen der Wohnung ziemlich hoch hält. Zudem haben wir leider sehr alte Fenster, die nicht sonderlich gut isolieren. Das ist zwar gut für eine ständige Frischluft-Zirkulation, aber weniger gut für konstante Wärme.
