SolusVM is a commonly used VPS management system by web hosting providers who are into VPS hosting services. It has support for OpenVZ, KVM and Xen virtualization.
As the underlying technology can vary, choosing and configuring the right solution for your servers is a cumbersome task. With our expert SolusVM tech support services, we’ll take care of all these tasks for you. (more…)
Docker enables easy deployment of applications inside containers and this makes it popular in hosting and development businesses. But proper management of the Docker system is essential to reap the benefits of this infrastructure setup.
A Docker container that always crashes, a host machine that doesn’t have enough space, an application that throws up errors – all these issues can cripple the effectiveness of using a Docker system for your business.
In a Docker infrastructure, the Docker containers are created using images. Containers are instances that are created when the image files are executed. These images can be of web servers, mail servers, applications, and so on.
Docker images are stored in locations knows as repository or registry. There are two types of repository – public registry (Docker hub maintained by Docker) and private repository (maintained by Docker users). (more…)
Docker containers are aimed at creating and managing application environments that can be deployed in the matter of a few seconds. Containers are usually created for temporary purposes, depending on its business application.
When a container’s application purpose is served, it can be deleted and the resources allotted to it can be reused for creating new containers for other purposes, especially when used in development and testing services.
In a Docker system, the containers are created based on images which are like templates. An image can be of an OS, webserver, mail server or any application that you require to create a container instance for.
Docker itself provides a set of container images for use by the public. These images are stored in a public repository known as the Docker hub. Users can download and upload their images from this docker registry.
Virtualization using Docker containers has gained popularity in application hosting, owing to its light-weight design and fast-deployment features.
Docker architecture is in such a way that the containers can connect to the outside world by default. But you cannot access the container directly from outside.
While disabling external access is a good security measure, there maybe many instances where you need to access the container data from outside, such as application testing, website hosting and so on. (more…)
Docker containers gained popularity as they enabled fast application deployment. This made them ideal solution for hosting applications and services. But to access these applications or services externally, we need to expose the docker ports.
While port forwarding is useful for end-users to access the container applications, developers and system administrators who manage the Docker infrastructure should have ways to connect to Docker containers from the backend.
Docker containers can be used for multiple purposes such as application deployment or service hosting. The number of containers that can be hosted in a machine depends on the total disk space available.
For cost-effective hosting purposes, it is often required to restrict the individual docker container size. This limitation is also useful to ensure that a single user do not use up the entire disk space in the host machine. (more…)
Due to its ‘light-weight’ reputation, container technologies such as Docker and LXC get a lot of attention from online businesses these days.
Docker and LXC are suited for different purposes. But in the flurry of information floating in the internet, these differences often get overlooked.
Docker containers can be used to host applications ranging from one-time testing to 24/7 web hosting instances. Depending on its purpose, the system setup can vary.
Every Docker machine runs a ‘docker’ daemon, which is required for the containers to function. But during instances such as server crash or reboot, this daemon may not get restarted. (more…)
