Top 7 Docker alternatives

Docker
Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.
The best Docker alternatives:


Chef


Chef turns infrastructure into code. With Chef, you can automate how you build, deploy, and manage your infrastructure. Your infrastructure becomes as versionable, testable, and repeatable as application code. Chef relies on reusable definitions known as recipes to automate infrastructure tasks. Examples of recipes are instructions for configuring web servers, databases and load balancers. Together, recipes describe what your infrastructure consists of and how each part of your infrastructure should be deployed, configured and managed.

Puppet


Puppet Enterprise is our flagship IT automation software that gives you the power to easily automate repetitive tasks, quickly deploy critical applications, and proactively manage infrastructure, on-premise or in the cloud. Automate tasks at any stage of the IT infrastructure lifecycle, including: discovery, provisioning, OS & application configuration management, orchestration, and reporting.

VMware vSphere


Build your own cloud infrastructure in your datacenter and remote sites on VMware vSphere the world’s leading server virtualization platform. Virtualize your x86 server resources and aggregate them into logical pools for allocation of multiple workloads. Get network services optimized for the virtual environment, along with simplified administration and management. Reduce the complexity of back-end storage systems and enable the most efficient storage utilization in cloud infrastructures.

OpenVZ


OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

Heroku


Heroku is the leading platform as a service in the world and supports Ruby, Java, Python, Scala, Clojure, and Node.js. Deploying an app is simple and easy. No special alternative tools needed, just a plain git push. Deployment is instant, whether your app is big or small.

Ansible


Ansible is the simplest way to automate IT. Automate in hours - not weeks - with Ansible's human-readable IT automation language. Ansible uses SSH instead of agents. More efficient, more secure and less to manage. App deployment, configuration management and orchestration - all from one system.
