Deployment patterns
Having covered the packaging and deployment models of cloud-native applications, we will now cover the patterns used for deploying cloud-native applications. Traditionally, applications get deployed in several environments such as development, testing, staging, pre-production, and so on, and each of these environments might be a scaled-down version of the final production environment. Applications move through a series of pre-production environments and get deployed finally to the production environment. However, one significant difference is that while downtime is tolerated in all other environments, downtime in a production deployment could lead to serious business consequences.
With cloud-native applications, it is possible to release software with zero downtime. This is achieved by the rigorous application of automation to every aspect of the development, testing, and deployment of the application. We will cover continuous integration (CI) / continuous deployment ...
