What Is Container Orchestration and How Does It Work?

Modern IT systems need to accommodate more data and more applications than ever before. In doing so, IT systems use containers to ensure continued operations and consume fewer resources. Although reliance on containers can create new challenges, orchestration can alleviate many problems related to app development.

Key Takeaways:

• The adoption of orchestration tools simplifies an otherwise complex environment of containers.
• Orchestration relies on the open-source Kubernetes system, which uses a control plane to deploy clusters to facilitate the management of containers within individual nodes.
• Proper orchestration of containers helps all moving parts in modern app development keep pace with the agility and dynamism of hybrid cloud technology and hyperconverged infrastructure (HCI).

What is container orchestration?

Containerization is a modern solution to the problems that physical hardware limitations can cause. By packaging software into remotely-accessible containers, it is possible to bypass restrictions and run an operating system in the public cloud and from other locations.

Although containers are lightweight and convenient, the execution of a single application can involve an overwhelming volume of containers. Container orchestration automates the deployment, networking, scaling, and management of containers in large numbers.

The Role of Kubernetes

Kubernetes is an open-source orchestration platform for managing containers in the enterprise setting. Platforms that use Kubernetes are rapidly-growing and highly-supported, with operators that can configure storage orchestration and automate containerization processes to their own specifications.

According to CNCF’s Kubernetes in 2025 Trends Report, container adoption remains strong, with about 84% of organizations actively using containers for development and production environments. The Voice of Kubernetes Experts 2025 Report (CNCF) further reveals that 41% of enterprises already operate with a mostly cloud-native application footprint, and 82% plan to make cloud-native environments—including containers—their primary platform for new applications within the next five years. 

Orchestration vs. Containerization: What’s the Difference?

What Are the Key Functions of Container Orchestration?

Container orchestration platforms — like Kubernetes and NKP — automate the operational lifecycle of containerized applications. Core functions include:

Provisioning and Deployment

• Automates cluster creation, node configuration, and service deployment
• Ensures consistent, repeatable environments across clouds and datacenters

Load Balancing and Traffic Management

• Distributes traffic across containers to maintain performance
• Automatically reroutes traffic during failures or scaling events

Scaling (Horizontal and Vertical)

• Adds or removes container instances based on demand
• Ensures applications remain responsive during usage spikes

Health Monitoring and Self‑Healing

• Continuously checks container and node health
• Restarts failed containers and reschedules workloads automatically

Configuration and Secret Management

• Centralizes environment variables, configs, and sensitive data
• Ensures consistent configuration across environments

Service Discovery

• Automatically assigns DNS names and endpoints
• Allows services to find and communicate with each other reliably

Security and Policy Enforcement

• Applies RBAC, network policies, and compliance controls
• Ensures workloads adhere to organizational governance

How Container Orchestration Works?

Container orchestration coordinates the lifecycle of containers through a set of core concepts:

• Clusters - A collection of nodes (physical or virtual) that run containerized workloads.
• Control Plane - The brain of the system — schedules workloads, manages state, enforces policies, and monitors health.
• Nodes - Worker machines that run containers and report status back to the control plane.
• Pods - The smallest deployable unit — typically one or more tightly coupled containers.
• Schedulers - Match workloads to nodes based on resource needs, constraints, and policies.
• Controllers - Maintain desired state — ensuring the number of replicas, health, and configuration match what you declared.
• Networking and Service Abstractions - Provide stable endpoints, load balancing, and cross‑service communication.
• Declarative Configuration - You define the desired state; the orchestrator continuously works to maintain it.

What Are the Benefits of Container Orchestration?

How Nutanix Simplifies Orchestration

Although Kubernetes is an open-source solution, re-architecting an IT environment is often costly. The common approach is to work with a platform provider that will help install and configure a unique orchestration platform with Kubernetes as its base. The configuration instructs the tool on where to find containers and store related logs, as well as how to establish a container network, all in accordance with a business’s needs.  

Orchestration is designed to simplify operations. But when searching for the right orchestration platform provider, simplicity is not the only thing to consider. It is also necessary to consider how a provider handles installation and how they resolve any problems that arise once the product is up and running.

The Nutanix Kubernetes Platform (NKP) delivers simplicity through a fully integrated approach. By providing a comprehensive container orchestration solution, NKP enables organizations to deploy clusters in a fraction of the time traditionally required.

Built on the Nutanix hyperconverged infrastructure (HCI), NKP seamlessly integrates into cloud-native environments, offering a unified platform that simplifies management and accelerates application modernization. With this setup, you can run anything anywhere–on one complete cloud native stack.

Container orchestration should not allow complexity to be visible to the operator; rather, orchestration should be simple enough to allow for focus on important outcomes. Learn more about building the perfect cloud-native platform for your workloads.

Frequently Asked Questions

How can container orchestration facilitate modern app development?

The application development process is rapidly evolving, meaning that companies must adopt the most modern technology. Cloud-native solutions comprise the present and future of development, and Kubernetes-powered orchestration helps make it possible.

Modern development is dynamic and takes place across private, public, and hybrid clouds. Management of this development must be efficient so that all moving parts can work together in harmony. The best way to achieve this is by running comprehensive container orchestration on HCI. Agility and efficiency are vital in the modern climate, so many companies have begun moving certain business-critical apps away from on-premises data centers and into the cloud. 

This complete migration to cloud-native methodologies is possible through advancements in containerization, orchestration, and virtualization. It serves to hasten app delivery and streamline internal processes, rapidly putting products in the hands of consumers.

How should we handle data for apps running in containers?

Handle application data with CSI-backed persistent volumes, encrypted at rest and scoped by RBAC. Protect it with snapshots and replication, then verify restores on a fixed cadence against documented RPO and RTO.

What’s the best way to run containers across regions or clouds?

Operate clusters as a governed fleet with shared policies, signed images, and GitOps for configuration. Mirror registries and configs per region to reduce external dependencies, while keeping day-2 operations local for speed.

How do we keep clusters secure?

Enforce least-privilege RBAC, default-deny network policies, and admission controls that block risky changes pre-deploy. Manage secrets with a central KMS and capture automated evidence so releases and audits share the same artifacts.

How can we manage Kubernetes costs while meeting performance goals?

Right-size requests and limits from measured usage, and scale with autoscaling policies tied to SLOs. Increase density with bin packing, enforce quotas, show back spend by team, and prune idle images and volumes. Place data on the correct storage tier.

What does disaster recovery look like for containerized applications?

Back up cluster state, manifests, and persistent data with clear retention rules, then replicate to a secondary region. Maintain runbooks for failover, validation, rollback, and planned failback, and rehearse regularly with evidence captured for improvement.
