Kubernetes vs Vagrant: What are the differences?

Introduction

Here, we will discuss the key differences between Kubernetes and Vagrant.

  1. Scalability and Orchestration: Kubernetes is designed for containerized application deployment, management, and scaling. It provides an out-of-the-box solution for orchestrating containerized workloads across a cluster of machines. On the other hand, Vagrant is a tool for creating and managing portable development environments. It focuses on providing consistent and reproducible development environments, rather than scaling and orchestrating containerized applications.

  2. Containerization Technology: Kubernetes utilizes containerization technology, such as Docker, to package applications and their dependencies. It provides features like service discovery, load balancing, and auto-scaling for containers. Vagrant, on the other hand, supports multiple virtualization technologies, including VirtualBox, VMware, and Hyper-V, to create and manage virtual machines.

  3. Infrastructure Abstraction: Kubernetes abstracts the underlying infrastructure, allowing developers to deploy and manage applications without worrying about the specific infrastructure details. It provides a uniform API for managing applications across different environments. Vagrant, on the other hand, focuses on providing a consistent development environment by abstracting the differences between development machines and targeted production environments.

  4. Community and Ecosystem: Kubernetes has a large and active community with extensive documentation, tutorials, and a wide range of third-party tools and integrations available. It is backed by major cloud providers like Google, Microsoft, and Amazon. Vagrant also has an active community, but it is relatively smaller compared to Kubernetes. However, Vagrant provides a rich ecosystem of plugins and supports a wide range of operating systems and tools.

  5. Deployment Complexity: Kubernetes is a complex system that requires a cluster of machines to run, along with additional components like etcd, kube-proxy, and kubelet. It requires knowledge of cluster management, networking, and distributed systems to set up and maintain. Vagrant, on the other hand, simplifies the deployment of virtual machines by providing a simple and declarative configuration file. It is easier to set up and does not require deep knowledge of distributed systems.

  6. Target Audience: Kubernetes targets organizations and developers who need to deploy and manage large-scale containerized applications in production environments. It is suitable for microservices architectures and cloud-native applications. Vagrant, on the other hand, is primarily targeted towards developers who want to create and manage portable development environments. It is commonly used for local development, testing, and sharing development configurations.

In summary, Kubernetes is a container orchestration platform designed for managing large-scale containerized applications, while Vagrant is a tool for creating and managing portable development environments. Kubernetes focuses on scaling, orchestrating containers, and providing infrastructure abstraction, while Vagrant focuses on providing consistent development environments and simplifying the deployment of virtual machines.

Decisions about Kubernetes and Vagrant
Michael Roberts

We develop rapidly with docker-compose orchestrated services, however, for production - we utilise the very best ideas that Kubernetes has to offer: SCALE! We can scale when needed, setting a maximum and minimum level of nodes for each application layer - scaling only when the load balancer needs it. This allowed us to reduce our devops costs by 40% whilst also maintaining an SLA of 99.87%.

Our whole DevOps stack consists of the following tools:

  • GitHub (incl. GitHub Pages/Markdown for Documentation, GettingStarted and HowTo's) for collaborative review and code management tool
  • Respectively Git as revision control system
  • SourceTree as Git GUI
  • Visual Studio Code as IDE
  • CircleCI for continuous integration (automatize development process)
  • Prettier / TSLint / ESLint as code linter
  • SonarQube as quality gate
  • Docker as container management (incl. Docker Compose for multi-container application management)
  • VirtualBox for operating system simulation tests
  • Kubernetes as cluster management for docker containers
  • Heroku for deploying in test environments
  • nginx as web server (preferably used as facade server in production environment)
  • SSLMate (using OpenSSL) for certificate management
  • Amazon EC2 (incl. Amazon S3) for deploying in stage (production-like) and production environments
  • PostgreSQL as preferred database system
  • Redis as preferred in-memory database/store (great for caching)

The main reason we have chosen Kubernetes over Docker Swarm is related to the following artifacts:

  • Key features: Easy and flexible installation, Clear dashboard, Great scaling operations, Monitoring is an integral part, Great load balancing concepts, Monitors the condition and ensures compensation in the event of failure.
  • Applications: An application can be deployed using a combination of pods, deployments, and services (or micro-services).
  • Functionality: Kubernetes as a complex installation and setup process, but it not as limited as Docker Swarm.
  • Monitoring: It supports multiple versions of logging and monitoring when the services are deployed within the cluster (Elasticsearch/Kibana (ELK), Heapster/Grafana, Sysdig cloud integration).
  • Scalability: All-in-one framework for distributed systems.
  • Other Benefits: Kubernetes is backed by the Cloud Native Computing Foundation (CNCF), huge community among container orchestration tools, it is an open source and modular tool that works with any OS.
