Docker vs Zookeeper: What are the differences?

Introduction

Docker and Zookeeper are both important tools in the field of software development and system management. While Docker focuses on containerization and packaging applications, Zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and group services.

  1. Operating System Layer vs Coordination Service Layer: Docker operates at the operating system layer, allowing applications to be packaged, shipped, and run in isolated containers. On the other hand, Zookeeper operates at a coordination service layer, providing distributed synchronization and configuration management for distributed systems.

  2. Purpose and Use Case: Docker is mainly used for creating and running containers that encapsulate applications and their dependencies, providing a consistent environment across different systems. In contrast, Zookeeper is specifically used for maintaining configuration information, naming, providing distributed synchronization, and group services in large distributed systems.

  3. Scalability and Performance: Docker focuses on scalability and performance of isolated containers, enabling efficient resource utilization and easy deployment of applications. Zookeeper, on the other hand, is designed to help in building robust and highly scalable distributed systems by providing coordination services.

  4. Single-purpose vs. Multi-purpose Tool: Docker is a single-purpose tool primarily used for containerization and application packaging, whereas Zookeeper is a multi-purpose tool that can be used for various coordination and synchronization tasks in distributed systems.

  5. Community and Ecosystem: Docker has a large and active community with extensive support and a wide range of tools and integrations available. Zookeeper also has a strong community backing, especially in the realm of distributed systems, providing robust solutions for coordination and synchronization challenges.

  6. Management Complexity: Docker simplifies application deployment and management by encapsulating applications and dependencies in containers, whereas Zookeeper adds a layer of management complexity by providing centralized coordination services, which require careful configuration and setup for efficient operation.

In Summary, Docker and Zookeeper differ in their core functionalities, operating layers, scalability, and management complexities, catering to specific needs in the software development and system management domains.

Advice on Docker, Zookeeper

Decided

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

What are some alternatives to Docker, Zookeeper?

Consul

Consul

Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.

Eureka

Eureka

Eureka is a REST (Representational State Transfer) based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers.

LXD

LXD

LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.

etcd

etcd

etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.

LXC

LXC

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.

rkt

rkt

Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.

Keepalived

Keepalived

The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures.

Vagrant Cloud

Vagrant Cloud

Vagrant Cloud pairs with Vagrant to enable access, insight and collaboration across teams, as well as to bring exposure to community contributions and development environments.

SkyDNS

SkyDNS

SkyDNS is a distributed service for announcement and discovery of services. It leverages Raft for high-availability and consensus, and utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights (more info here: http://blog.gopheracademy.com/skydns).

SmartStack

SmartStack

Scaling a web infrastructure requires services, and building a service-oriented infrastructure is hard. Make it EASY, with SmartStack’s automated, transparent service discovery and registration: cruise control for your distributed infrastructure.
