Azure Cosmos DB bulk delete with TTL

Azure Cosmos DB

Working with Azure Cosmos DB usually is a pleasure. The initial setup process is fast and easy, working with documents very intuitive and once you go to production you don’t encounter any scaling barriers. It might not be the cheapest database out there, but you get what you pay for. Weiterlesen

Build a Powershell Module in the Windows Linux Subsystem

Since Powershell Core supports Linux, you might want to test your Powershell Module if it works on Linux as it works on Windows. You could setup a virtual machine, which is a litte time consuming and cumbersome. You could use a continous integration service like AppVeyor which does not allow to debug if the test fails.
Another option would be Docker. But anyway i tested the Windows Linux Subsystem (WLS) and it’s pretty good! Weiterlesen

DevOps und der Microsoft BI Stack

DevOps findet immer größere Verbreitung bei IT-Projekten. Ob im StartUp, beim Mittelständler oder im Konzern-Umfeld, kann der DevOps-Modus für Projekte handfeste Vorteile bringen, die sich von Fall zu Fall leicht unterscheiden können. Sei es Strukturierung der Prozesse für kleine Projekte, wo Trennung von Entwicklung, Betrieb und Qualitätssicherung nicht wirtschaftlich waren. Oder sei es für große Projekte, in denen Planung, Kommunikation und Abnahmen zu größeren Zeitspannen zwischen Anforderung und GoLive führen und damit zum Projektrisiko wurden. Allgemein sollen sich Qualität, Geschwindigkeit und Soziales Klima verbessern. BI-Projekte nehmen hier häufig eine Sonderrolle ein. Das ist aber nicht notwendig.

Steffen Kampmann von der Tekaris GmbH hat dazu einen Vortrag bei der PASS Bayern gehalten. Der Vortag erklärt die zentralen Konzepte und Methoden von DevOps, die Besonderheiten in BI-Projekten, die technischen Lösungsansätze von Continuous Deployment in Microsoft SQL Server mit ihren Alltagsproblemen und einen Erfahrungsbericht.

Dazu sind auch Folien Github Repository der PASS Bayern veröffentlicht worden.

Mentoring

Mentor

/ˈmɛntɔː/

noun

  1. an experienced and trusted adviser.
    "he was her friend and mentor until his death"
    synonyms: adviser, guide, confidant, confidante, counsellor, consultant, therapist.

verb

  1. advise or train (someone, especially a younger colleague).

During my career so far, I have been at different companies, in different countries. I have had the pleasure to work with many different colleagues from different cultures. This leads to learning a lot of different approaches to dealing with situations in the work-place, as well as individual growth.

For some people individual growth and/or dealing with work-place situations comes easier than for others, but in any case, a form of guidance makes dealing with these two aspects of a career a lot more managable. Even though one might not feel like they have a need for a mentor, it never hurts to have somebody available.

Personally I’ve had multiple mentors up until now, either because one was proposed to me by my employer, because they felt it was good to have such a resource available, or because I requested somebody to be my mentor, or because quite simply… They never actually found out I considered them a mentor for me. One might argue that in a way these people are role-models, but then again, these were role models I had access to. I could ask them questions. I could make mistakes in front of them, and they would be able to help me avoid making the same, or similar mistakes in the future. Weiterlesen

As Native as it Gets – Getting in Touch with NativeScript

About

When it comes to Mobile App Development, there are basically two approaches you can adopt to get on track. You can either go for native development with Swift for iOS and/or Java/Kotlin for Android, or for a cross-platform solution. Cross-platform solutions allow for writing a single code base while being able to deploy the application on several target operating systems. Cross-platform solutions comprise the two approaches truly native and hybrid development.
This article classifies the different approaches before going into detail with NativeScript – a framework which allows for writing native applications entirely with web technologies, e.g. JavaScript/TypeScript and Angular. Weiterlesen

DevOps – Digitale Transformation bis zum Betrieb

Als Ziele digitaler Transformation gelten folgende, scheinbar im Widerspruch befindliche Ziele:

  • erhöhte Geschwindigkeit, um Software schneller an den Kunden zu bringen oder geänderte Anforderungen und Kunden-Feedback schneller umzusetzen
  • Realisierung von Kostensenkungen
  • und erhöhte Qualität.

Schnelle Entwicklungszyklen bei hoher Qualität und sicherem Betrieb.
Software, die Business- und Qualitätsziele erfüllt und Compliance-Anforderungen genügt, wird automatisiert ausgerollt – und der Betrieb läuft. Idealerweise gilt: Jedes Inkrement an Änderungen am Code ist potentiell sofort auslieferbar (potentially shippable increment), ohne Qualiätsverluste. Weiterlesen

User Experience (UX) – Usability and Beyond

Popular applications do not owe their success to the fact that they only do what they are functionally supposed to do. Successful applications do so in an intuitive, efficient and ideally even fun to use way. You might have stumbled upon the terms User Experience (UX) and Usability. While often used synonymously, they bear a different meaning. There are many articles that take up that issue and illustrate the differences and similarities between the two terms. In fact, this article won’t go without at least a short definition and classification of User Experience and Usability. However, beyond that, it is supposed to give a short introduction on how to create usable, fashionable and fun to use applications by going into the design process and thus trying to provide you with an appropriate mindset in order to create applications with high usability and a good User Experience yourself.

Providing a Web API for your system – An introduction

Imagine wanting to develop an application which has the main purpose to store, process and deliver data. Your data model is mature enough, you have a decent interface in place. Basically, the whole application is functioning well as a whole and is technically fulfilling its primary requirements. But what is the next step? The users of the platform might want to run statistics or analysis? The interface is not to the liking of all users? Or maybe it would be nice if the platform could be used from other applications through integration with add-ons or such? How would we go about that? Weiterlesen

PaaS Security – Denn sie wissen, was sie tun

Die Entwicklung von Cloud-Anwendungen mit Azure PaaS bietet viele Vorteile für Unternehmen. Das Microsoft Data Center kümmert sich um die Verwaltung des Betriebssystems und des Application Servers. Für Unternehmen bedeutet das eine enorme Zeit- und Kostenersparnis.
Viele Unternehmen zögern jedoch aus Sicherheitsbedenken und Datenschutzgründen und bevorzugen den Betrieb im hauseigenen Rechenzentrum. Dabei ließe sich durch aktuelle Sicherheitstechnologien die Sicherheit von Public-Cloud-Anwendungen erheblich verbessern.
Dazu muss der Anwendungssicherheit in der System- und Anwendungsarchitektur jedoch genügend Raum gegeben werden. Wichtig ist es, die möglichen Bedrohungen zu analysieren und entsprechende Maßnahmen vorzusehen. Weiterlesen
