There are several technical and business advantages associated with Docker. The longstanding goals of application development, deployment, and delivery automation are accomplished through Docker-enabled containerization, which is being touted as a crucial automation method for the tremendous success of the cloud paradigm. Existing workloads are containerized and cloud-enabled to be stocked in public as well as private repositories. Both business and IT workloads can be easily pampered, packaged, and presented as remotely discoverable, usable, portable, and composable containers. Further on, containers are shipped and run everywhere without any hassle, hitches, and hurdles. The containerization concept has made IT infrastructures and processes agile and adaptive. This means that not only is software engineering sped up, but also the tasks of software configuration, deployment, and delivery are accelerated. Precisely speaking, the unique goals of DevOps are accomplished through the smart use of containers.
Beside a litany of Docker-centric solutions, there is a growing family of third-party tools to make embracing and enabling Docker risk-free, easier, and faster. There are powerful case studies and real-world deployments clearly illustrating that Docker consistently contributes to establishing and sustaining IT environments in minutes rather than in months. The other noteworthy advancements brought by the Docker paradigm include the real-time scalability of application infrastructures and the improved utilization of IT resources brought about by having several application containers within any Docker host. There are container cluster management platforms for efficient container scheduling, and orchestration for quickly producing and sustaining multihost, multicontainer, and microservices-centric distributed applications.
The role and responsibility of the widely deliberated Docker technology in ensuring event-driven, service-oriented, insights-filled, context-aware, cloud-hosted, business-centric, and mission-critical applications is enchanting really and is well articulated in this new edition of the book, in order to adequately empower our readers with all the relevant details of the most popular Docker paradigm.
