Explanation: Orchestration is the best option for coordinating the processes of several applications and assigning a manager to oversee the technical coordination to improve efficiency. Orchestration is the combined automation of apps, workloads, supporting resources, and infrastructure across one or more cloud platforms1. It commonly includes imperative and/or declarative methods to drive automation1. Orchestration introduces and enforces a workflow for automated activities of various processes to deliver the desired service to its client2. Orchestration helps IT organizations reduce manual, repetitive work, better standardize their deployments and operations, and accelerate delivery1. Orchestration also enables businesses to easily add or remove computing resources, on demand, without significant hardware investment or infrastructure changes2. Orchestration ensures that businesses can efficiently and seamlessly handle varying workloads, optimize resource utilization, and enhance the overall reliability and performance of cloud computing systems3.
Orchestration is different from the other options listed in the question, which are not directly related to coordinating the processes of several applications. Scripting is the use of code to perform a specific task or operation on a single component of an application, workload, resource, or infrastructure within a cloud platform1. Scripting is one of the building blocks for delivering cloud orchestration, but it does not provide the coordination, arrangement, or end-to-end automation of the deployment of services in a cloud-based environment2. Continuous integration is the practice of merging code changes from multiple developers into a shared repository frequently, usually several times a day, to detect and resolve errors early4. Continuous integration is a part of the DevOps methodology, which aims to improve the quality and speed of software delivery, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1. Continuous delivery is the practice of releasing software updates to production in small increments, usually after passing automated tests, to ensure that the software is always in a deployable state4. Continuous delivery is another part of the DevOps methodology, which aims to reduce the risk and cost of software deployment, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1.
