A list of different release patterns for different use cases — To decouple deployments from our releases that are driven by our marketing launching date, we can use certain release patterns. We avoid setting up deployments for Friday nights or weekends in order to reduce the risk of negative impacts on customers. Continuous Delivery allows for deployments during normal business hours…

Let us take a look into winston logging, integrate it in a NestJS application and create centralized logging with Loki and Grafana — Nowadays it is important to log your applications for better monitoring, debugging and failure handling (for example, in a Kubernetes cluster), and to ensure centralized logging for a better overview of a distributed system. There are numerous applications and frameworks that make this possible. But in this series I want…

Integrated test stages are important for every Deployment Pipeline — Automated tests should be used by every developer in our daily work. Integrating them in your work creates a fast feedback loop, finding problems or bugs early on and fixing them as soon as possible if there are no fix constraints (release-date, end of iteration, resources, etc). Deployment Pipelines are…
