AWS Copilot vs Kubernetes: What are the differences?
Introduction
AWS Copilot and Kubernetes are both popular options for container orchestration and management. While they share similarities, there are key differences between the two. In this article, we will explore six main differences between AWS Copilot and Kubernetes.
Managed Service vs. Self-Managed: The most significant difference is that AWS Copilot is a managed service provided by Amazon Web Services (AWS), while Kubernetes is a self-managed open-source platform. With AWS Copilot, the infrastructure and control plane are managed by AWS, reducing the operational overhead for users. On the other hand, Kubernetes requires users to set up and maintain their own infrastructure and control plane.
Level of Abstraction: AWS Copilot aims to provide a higher level of abstraction compared to Kubernetes. It abstracts away the underlying infrastructure details and focuses on simplifying the deployment and management of containerized applications. In contrast, Kubernetes provides a lower level of abstraction, giving users more control and flexibility, but also requiring more configuration and management effort.
Ease of Use: AWS Copilot is designed to be user-friendly and beginner-friendly. It provides a command-line interface (CLI) with simplified commands and intuitive workflows, making it easier for developers to deploy and manage their applications. Kubernetes, on the other hand, has a steeper learning curve and requires more configuration and setup. It is more suitable for experienced DevOps teams or users with a deeper understanding of container orchestration.
Vendor Lock-in: As a managed service, AWS Copilot has a level of vendor lock-in since it is tightly integrated with AWS services. Users who choose to use AWS Copilot will have limited portability to other cloud providers. On the contrary, Kubernetes is an open-source platform that can run on various cloud providers or even on-premises, offering more flexibility and avoiding vendor lock-in.
Ecosystem and Community: Kubernetes has a vast and mature ecosystem with a strong community support. It has a wide range of third-party tools and integrations, making it a versatile choice for various use cases. AWS Copilot, being a relatively new service, has a smaller ecosystem and community. It may not have the same level of flexibility and extensibility as Kubernetes at the moment.
Cost Considerations: When it comes to cost, there are differences between AWS Copilot and Kubernetes. With AWS Copilot, users are billed based on the underlying AWS resources they utilize, while Kubernetes itself is free, but users are responsible for the cost of managing and maintaining the infrastructure. The cost implications for each option will depend on the specific use case and the scale of the deployment.
In Summary, AWS Copilot is a managed service offered by AWS with a higher level of abstraction and easier to use interface, but it comes with a level of vendor lock-in. Kubernetes, on the other hand, is a self-managed open-source platform with a lower level of abstraction, offering more flexibility and broader community support. The choice between the two will depend on the user's needs, skills, and preferences.
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.
