Why Use Kubernetes: Overview

Before discussing Kubernetes, let’s first explore what containers are all about!

Containers are a method of packaging software that can run reliably on different computers. They bundle an application with everything it needs, like code, libraries, and settings, into one lightweight unit. This ensures the application works similarly from a developer’s laptop to a data center or the cloud.

On the other hand, “Kubernetes is a platform for managing and orchestrating these containers, especially at scale.” It becomes necessary when you need to deploy, scale, and operate countless container instances and services, and this is where Kubernetes comes to your rescue. It automates the complexities of container orchestration, making your life easier and your deployments smoother.

Born at Google, now overseen by the Cloud Native Computing Foundation (CNCF), Kubernetes is constantly evolving with the help of a vibrant community.

Kubernetes Architecture

A Kubernetes cluster represents the architecture used to deploy Kubernetes.

Kubernetes Architecture consists of two main parts:
1. Control Plane: Manages the cluster.
2. Nodes: Compute machines where containers run.

Note: Nodes can be physical or virtual machines. Each node runs pods, which are groups of containers that work together.

Key Components

1. Control Plane

Imagine smart city
API Server: This server is the central hub for managing interactions within the Kubernetes cluster. It processes requests and manages application lifecycles.
Scheduler: Determines optimal locations for deploying new pods, considering resource availability and overall cluster health.
Controller Manager: This person maintains consistency between the cluster’s current and desired states by overseeing and adjusting pod and node configurations.
etcd: Serves as a reliable distributed storage system that stores essential configuration and state data for the Kubernetes cluster.

2. Nodes

Kubelet: Each node hosts a Kubelet agent that communicates with the control plane to oversee pod management and ensure proper execution of their containers.
Container Runtime Engine: Software tools, such as Docker, manage the execution and lifecycle of containers within Kubernetes.
Kube-proxy: Handles network communication and load balancing among pods in the Kubernetes cluster.

Core Concepts

  • Pods: These are the fundamental units in Kubernetes where one or more containers share storage and network resources. They can be adjusted in scale, updated, or swapped out as necessary.
  • Services: Kubernetes provides stable endpoints for accessing pods, enabling communication within the cluster and with external users.
  • Replica Sets: This feature guarantees a designated number of pod duplicates are operational at all times, ensuring dependability and the ability to handle increased workload demands.
  • Benefits of Kubernetes

    Here are the various reasons that answer your questions about why use Kubernetes and what makes it stand out!

    Benefits of Kubernetes

    Resource Efficiency

    Kubernetes optimizes resource usage by letting users set resource requests (minimum required CPU, memory, etc.) and resource limits (maximum allowable resources) for their pods. These settings can be easily applied at the container, pod, or namespace level, ensuring applications have the needed resources. All of these factors prevent underutilization and over-allocation of resources, which simply reduces the operational costs and maximizes the efficiency of infrastructure investments.

    Increased DevOps Efficiency for Microservices Architecture

    Kubernetes streamlines development, testing, and deployment by simplifying container integration and storage access across cloud providers. Creating container images is always more efficient than creating virtual machine images, which leads to faster development and optimized release times. Early adoption of Kubernetes in the development lifecycle allows for early code testing, reducing costly errors later on.

    For microservices-based applications, where each component functions independently and communicates via APIs, Kubernetes supports forming smaller, focused development teams and boosts IT operational efficiency. Additionally, Kubernetes namespaces create virtual sub-clusters within a single physical cluster, improving access control and operational efficiency.

    Faster-Time To Market

    Kubernetes supports a microservices approach, where development teams focus on smaller, specialized tasks. This setup speeds up development by reducing dependencies between teams. It also simplifies container management, ensuring communication between containers and storage services like AWS and Azure.


    One of Kubernetes’s most important selling points is its scale capability, allowing projects to adjust resource usage based on demand. The architecture is divided into four types of scaling:
    1. Horizontal Scaling: Adjusts the quantity of pod replicas based on fluctuating workload demands.
    2. Vertical Scaling: Allocates more memory and CPU to the running pods whenever required.
    3. Cluster Scaling: Adjusts the number of cluster nodes based on their current usage
    4. Multidimensional Scaling: Combines vertical and horizontal scaling methods for optimized performance across different aspects.

    These capabilities help handle unpredictable growth by efficiently matching resource requirements. Kubernetes ensures operations remain cost-effective while maintaining optimal performance.


    Kubernetes automates essential tasks like
    1. Service discovery: Automatically finding and connecting applications or services within the cluster.
    2. Load balancing: Automatically routes network traffic among several instances of an application or service to enhance operational efficiency.
    3. Failover: Automatically redirect traffic to healthy instances or nodes when any failure occurs.

    Automation reduces reliance on manual intervention and streamlines operations, allowing teams with limited staff and resources to focus on core activities.

    Portability with Minimum Vendor Lock-In

    Kubernetes enhances portability, allowing applications to run across different environments, including on-premise infrastructure, cloud providers, or a combination. It simplifies the software development life cycle(SDLC), making it easier to adapt to changing needs or choose different infrastructure options.
