Amazon ECR vs Kubernetes: What are the differences?

Deployment Management: One key difference between Amazon ECR and Kubernetes is their approach to deployment management. Amazon ECR provides a managed container registry service, allowing you to store, manage, and deploy container images. On the other hand, Kubernetes is a container orchestrator that focuses on managing the deployment, scaling, and monitoring of containerized applications across a cluster of nodes.
Container Orchestration: While Amazon ECR focuses primarily on container image storage and deployment, Kubernetes offers a comprehensive container orchestration solution. Kubernetes provides features such as automated scaling, load balancing, rolling updates, and resource allocation. It helps manage the entire lifecycle of containers and ensures their availability, scalability, and fault tolerance.
Infrastructure Independence: Another difference is that Amazon ECR is tightly integrated with AWS infrastructure, making it a convenient choice for users already using other AWS services. Kubernetes, on the other hand, is platform-agnostic and can run on various cloud providers or on-premises environments, giving users the flexibility to deploy and manage containers irrespective of the underlying infrastructure.
Autoscaling and Self-Healing: Kubernetes offers built-in functionality for autoscaling and self-healing of containerized applications. It allows you to define and configure horizontal or vertical pod autoscalers based on metrics like CPU or memory usage. In contrast, Amazon ECR solely focuses on managing container images and does not provide native autoscaling or self-healing capabilities.
Community and Ecosystem: Kubernetes has a vibrant open-source community and a wide-ranging ecosystem of tools and extensions. It benefits from the collective contributions and support of various organizations and developers. Amazon ECR, being a managed service, has less community involvement or extension possibilities compared to Kubernetes. However, it integrates well with other AWS services, providing a seamless experience for users of AWS infrastructure.

In summary, Amazon ECR is primarily focused on container image storage and deployment, tightly integrated with AWS infrastructure, while Kubernetes is a full-fledged container orchestrator with infrastructure independence, extensive community support, and a range of container management capabilities.

@{PostgreSQL}|tool:1028| as preferred database system
@{Redis}|tool:1031| 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.

Detailed Comparison

Kubernetes	Amazon ECR
Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.	It is a fully managed container registry that makes it easy to store, manage, share, and deploy your container images and artifacts anywhere. It eliminates the need to operate your own container repositories or worry about scaling the underlying infrastructure.
Lightweight, simple and accessible;Built for a multi-cloud world, public, private or hybrid;Highly modular, designed so that all of its components are easily swappable	Reduce your effort with a fully managed registry; Securely share and download container images; Provide fast and highly available access; Simplify your deployment workflow

What are some alternatives to Kubernetes, Amazon ECR?

Rancher

Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

Docker Compose

With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.

Docker Swarm

Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

Tutum

Tutum lets developers easily manage and run lightweight, portable, self-sufficient containers from any application. AWS-like control, Heroku-like ease. The same container that a developer builds and tests on a laptop can run at scale in Tutum.

Portainer

It is a universal container management tool. It works with Kubernetes, Docker, Docker Swarm and Azure ACI. It allows you to manage containers without needing to know platform-specific code.

Codefresh

Automate and parallelize testing. Codefresh allows teams to spin up on-demand compositions to run unit and integration tests as part of the continuous integration process. Jenkins integration allows more complex pipelines.

CAST.AI

It is an AI-driven cloud optimization platform for Kubernetes. Instantly cut your cloud bill, prevent downtime, and 10X the power of DevOps.

k3s

Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server.

Flocker

Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.

Kitematic

Simple Docker App management for Mac OS X
