Defining Day-2 Operations - DZone
Day-2 operations doesn't necessarily refer to the 2nd day of operations. Sorry for being Captain Obvious here [sic] but let's clear this up. Once "something" goes into operations, "day 2 operations" is the remaining time period until this "something" isn't killed or replaced with "something else." When we look at the various stages in the life of a business process, application or an IT infrastruc
14 Stances of Highly Effective Product Owners - DZone
The role of the Scrum Product Owner is probably the most misunderstood of the three Scrum Roles. As I look back at the different incarnations and interpretations I have seen of Product Ownership, I thought it was time to articulate the different stances I thought an effective and professional Scrum Product Owner might consider. Inspiration Besides my industry experience, my ideas were influenced b
Optimizing Product Backlog Refinement - DZone
I've recently been involved with several Scrum Teams that are struggling to have the right level of detail in their Product Backlog items.| Some symptoms: difficulty during Sprint Planning sessions, a massive or very small Product Backlog, or a lack of understanding during a Sprint. All of the teams I spoke with had refinement activities in place. It is important to note that Product Backlog refin
11 Ideas to Spice up Your Retrospective - DZone
This week, I got a question from a colleague about the Scrum Retrospective. She’s Scrum Master of a team that for sure has room for improvement. However, somehow, during the Retrospective, nobody is really challenging each other and the burning issues aren’t discussed. Therefore, the Retrospective often results in defining only small improvements. So the question I want to discuss in this blog pos
Microservices — Myths and Misunderstandings - DZone
Microservices Aren't Micro Enough !While the definition of microservices is clear, interpretation of it is very different within the development community. Some questions are, Is it single entity representation?Is it single service representation?Is it a logical functional group?Let’s take an example of a banking application for the sake of this discussion, 3-tier architecture solved the problem o
Microservices in Practice: From Architecture to Deployment - DZone
Microservices is one of the most popular buzz-words in the field of software architecture. There are numerous learning materials on the fundamentals and benefits of microservices, but there are very few resources on how you can use microservices in real-world enterprise scenarios. In this post, I'm going to cover the key architectural concepts of the Microservices Architecture (MSA) and how you ca
13 Things That Make a Good Build System - DZone
When recently looking for a replacement for our internal build system, I wrote out a wish list of what I wanted in a build system. This post will describe the thought process around that wish list and why eventually we decided CircleCi was the best solution that fit all these points. Existing Build SystemOur starting code was a single Java repository with dozens of submodules, but now includes Go
Under The Boot – Spring Boot - DZone
Remember the times when we had to register dispatchers, viewResolvers, etc. to make our spring application web app? Then there was @EnableWebMvc annotation, and now even this is redundant. These days the only thing you need to do is to add org.springframework.boot:spring-boot-starter-web dependency to your project and everything else is done automagically. The same goes for a database connection.
Java WebSockets (JSR-356) on Jetty 9.1 - DZone
Jetty 9.1 is finally released, bringing Java WebSockets (JSR-356) to non-EE environments. It's awesome news and today's post will be about using this great new API along with Spring Framework. JSR-356 defines concise, annotation-based model to allow modern Java web applications easily create bidirectional communication channels using WebSockets API. It covers not only server-side, but client-side
Functional Testing For Node.js Using Mocha and Zombie.js - DZone
In Agile development, developers write tests before the implementing a feature. Unit tests should already be in your ADN, so let's talk about functional tests instead. Functional tests are the technical translation of the acceptance tests written by the customer at the back of a user story card. Let's see how to achieve functional testing for Node.js applications. Contact Should Be Easy The custom
Blog Rolling with MongoDB, Node.js and Coffeescript - DZone
This morning I woke up with a lingering thought on my mind that was left over from recent conversations. In the technical community we often get so invested in our work that rather than talk about the simple building blocks that build our success we talk about the huge breakthroughs we make. The problem however is that our breakthroughs most often aren’t accessible to someone who wants to just get
CoffeeScript: a TDD example - DZone
CoffeeScript is a language building an abstraction over JavaScript (as the similar name suggests.) It is an abstraction over the syntax of JavaScript, not over its concepts: the language is still based on functions as objects which may bind to other objects, and prototypical inheritance. CoffeeScript favors the best practices of JavaScript by transforming abstractions you would have written anyway
