Kubernetes vs Tectonic: What are the differences?
Kubernetes vs Tectonic
Kubernetes and Tectonic are both popular container orchestration platforms, but they have some key differences. Let's explore these differences in detail:
Architecture: Kubernetes follows a master-worker architecture, where there is a central control plane (master) that manages multiple worker nodes. Tectonic, on the other hand, builds upon Kubernetes and adds more components for enterprise-grade features like monitoring, logging, and security.
Ease of Deployment: Kubernetes can be complex to set up and deploy, requiring manual configuration of various components. Tectonic, however, provides an installer that simplifies the deployment process by automating the setup and configuration of Kubernetes and its additional components.
Support and Maintenance: Kubernetes is community-driven and has a large user base, which means there is extensive community support available. Tectonic, being a commercial offering by CoreOS, provides enterprise-level support and maintenance services along with regular updates and bug fixes.
Additional Features: While Kubernetes provides a solid foundation for container orchestration, Tectonic extends it with additional features like integrated monitoring and logging solutions, enhanced security controls, and a web-based user interface for easier management and visibility into the cluster.
Vendor Lock-In: Kubernetes is an open-source platform that is not tied to any specific vendor, allowing users the flexibility to choose their underlying infrastructure. Tectonic, on the other hand, is associated with CoreOS and its ecosystem, which may lead to a certain level of vendor lock-in.
Pricing: Kubernetes is free to use, being an open-source project. However, if you opt for the managed Kubernetes services offered by cloud providers, you may incur charges for the resources used. Tectonic, being a commercial product, comes with pricing based on the number of nodes deployed and additional support services.
In summary, Kubernetes is a widely adopted open-source container orchestration platform, whereas Tectonic is a commercial product that extends Kubernetes with enterprise-grade features and services. The choice between the two depends on specific requirements, ease of deployment, desired additional features, maintenance support, and pricing considerations.
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.
