According to trusted sources, the global container orchestration market will grow by 16.8%. This will happen between 2024 and 2030. The market was valued at USD 865.7 million in 2024 and is expected to reach USD 2,744.87 million by 2030.
How does container orchestration work?
Container orchestration platforms differ in features, capabilities, and deployment methods. But, they share some similarities.
Platforms employ unique container instrumentation methods. Instrumentation tools engage with user-generated YAML or JSON files directly. These files detail the configuration requirements for applications or services. They define the details. They say where to find container images and how to network between containers. They also say where to store logs, and how to add storage volumes.
In addition, orchestration tools manage the deployment of containers between clusters. They make informed decisions about the ideal host for each container. Once the tool selects the host, it ensures that the container meets the specs. It does so throughout its lifecycle. It involves automating and monitoring the complex interactions of microservices in large applications.
