The revolutionary tech has changed the scenario of IT industry. Among the tonnes of innovation one is Docker. If you aren’t aware about Docker what actually it is and it’s functionality then go through the post. The Docker allows you to incorporate and record code and its dependencies into an image. This can be further used to spawn an instance of any application as a container. The basic difference between containers and Virtual Machines is that containers don’t contain a hardware hypervisor. Well, if you have clicked to read on Best Docker Alternatives then let us assume you already know about it and if not then Tricky Bell is always here.
What is Docker?
Docker is a set of interoperating software-as-a-service and platform-as-a-service offerings that give OS-level virtualization. And to create development and delivery of software inside standard set software packages which is containers. The software which will host the containers is known as Docker Engine It is there since the year 2013. And is developed by Docker, Inc. The service has both free and monetary options
Containers are separated from each other and bundle their own software, libraries and configuration files. They can communicate with each other through well-defined channels. All containers are run by a single OS kernel and are hence more lightweight than virtual machines. Images are often created by combining and modifying standard images downloaded from public repositories.
According to a Linux.com article,
Docker is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. This helps enable flexibility and portability on where the application can run, whether on premises, public cloud, private cloud, bare metal, etc. Because Docker containers are lightweight, a single server or virtual machine can run several containers simultaneously. A 2016 analysis found that a typical Docker use case involves running five containers per host, but that many organizations run 10 or more
Anyways, let’s talk more the handmade list we made for you. So, here is the list of Best Docker Alternatives.
Best Docker Alternatives To Use
rkt spelt as Rocket is probably the worthy application in our list of Best Docker Alternatives. From the infamous Linux Distributers, released by CoreOS in 2014. Also a part of Cloud Native Computing Foundation. It supports multiple container formats and has very few third part integrations available. Also packs Public cloud portability, Stateful app migration, and Rapid Deployment. Popularly used by companies like CA Technologies, Verizon, Viacom, Salesforce.com, DigitalOcean, BlaBlaCar, Xoom etc
Next on our list is LXD or Lexdi, as we know it. Developed by Canonical Ltd, popularly known to have developed Ubuntu. Also released in 2014 but as more emphasis on offering full system containers and is OS centric rather than being application based. LXD daemon requires a Linux kernel which needs to get configuration for access by either a Windows or a Mac OS client. It has Bare-metal hardware access for VPS and multiple Linux distributions on a single host. Popular clients include PayPal and Walmart.
3. Linux VServer
Through a Linus VServer, you would get an operating system-level virtualization capability which needs to be patched Linux kernel. Individual Virtual Private Servers is run as a singular isolated process on the same host system and there is always a higher efficiency that no emulation is required. Linus VServer gets you Multiple VPS Hosting with Administration. Also used DreamHost, OpenHosting Inc., Lycos, France, Inc etc
4. Windows Containers
Probably the easiest to use in our list of Best Docker Alternatives is Windows Containers. Released in 2016 while currently there are two models i.e. Windows Containers and Hyper-V Containers. As Docker Engine for WindowsServer 2016 directly accesses the windows kernel, therefore, the Docker’s code would need a separate app called WSC (Windows Server Container).
5. Open VZ
Next, we have Open VZ, it is an extension of the Linux kernel, which provides tools for virtualization to the user. It uses Virtual Environments to host Guest systems, means it uses containers for the whole OS, no individual applications and processes required. Packs features like CI/CD and DevOps, Containers and big data, Hosting Isolated Set of User Applications, Server consolidation and much more. In use by FastVPS, Parallels, Pixar Animation Studios.
