In an industry where failure is unavoidable, learning and innovating through feedback loops is your best course of action. Instead of focusing on increasing the time until your next failure, you should focus on decreasing the time it takes for your systems to recover following a failure ...
Agile
DevOps means a mindset of getting better at getting better. You need to get better to fulfill customer needs, and therefore you need to get interested in what your customer wants and make sure the feedback loop will be as short as possible. How do you reach the state of "get better at getting better"? ...
When I was an active football player one summer I wanted to do extra training. I skipped the leg training, because I did some running as well, but the trainer said "never skip a leg day". What does this have to do with DevOps? ...
As dev teams and product owners begin the Agile development process, they meet to discuss how users will interact with their applications. They write these user stories down on sticky notes or index cards, arranging and re-arranging them into an order that they feel makes sense. These stories create the basis of their Agile requirements process. When done poorly, user stories lead to missed or misunderstood requirements which 96% of application development and delivery professionals blame for project delays and rework ...
Here are three examples of SLI patterns that you will encounter as you embark on your SAFe implementation journey, as well as ways in which you might use them ...
Factories scale well and have a strong tendency to get more efficient as they get bigger. So why is it, then, that building software seems to have the opposite effect of reducing efficiency as you scale up? Dean Leffingwell, the creator of Scaled Agile Framework (SAFe), noted that building large scale systems is fundamentally a social event – not a manufacturing event ...
Times are changing. With the imperative to deliver applications faster, developers are increasingly stepping outside their traditional skill-zones and leveraging new automated capabilities – allowing them to develop and test in parallel, while releasing software continuously. In essence, they're not only writing great music, but also building the instruments upon which to play it ...
A shift to continuous integration (CI) and other agile methodologies is driving a massive change in the way that development and testing professionals approach testing, according to an independent, global developer survey titled Web and Mobile Testing Trends ...
Although the exact role and responsibilities of DevOps may not be defined across the board, it has to be able to rapidly deal with issues rising from the code and from the connection between the code and production environment. These responsibilities may include release management, configuration management, and dealing with problems (bugs) that find their way to the production environment. In this blog, I will focus on the latter and examine the tools and methods that can help expedite this process in order to cope with these continuous changes ...
