Containers have definitely simplified how we build, deploy, and manage software applications by abstracting the underlying infrastructure. That is, developers just focus and develop software applications. Then, the developed applications get packaged in a standardized fashion, and shipped and deployed on any system without any hitches and hurdles. They can run on local systems as well as remote systems. With clouds emerging as the one-stop IT infrastructure solution for running and managing all kinds of enterprise, web, cloud, mobile, and IoT applications, applications are being containerized and deployed in cloud environments, through a host of automated tools. However, there is a need for a number of automated tools to automate the end-to-end activities of application development, integration, delivery, and deployment. Furthermore, an application's availability, scalability, adaptivity, stability, maneuverability, and security have to be ensured through technologically inspired solutions. Service mesh solutions have emerged as one of the important ingredients of containerized cloud environments and contribute immensely in elevating service resiliency. In the next chapter, we will be learning about how to use Prometheus and Grafana metrics to create powerful dashboards and alerts.
