Python has many web frameworks, and it’s always a tough choice for a developer to options down to a single framework of the most popular programming language. Python offers both micros as well as full-stack web frameworks. With microframeworks like Flask, we have full control over the web application flow, but we have to write code for every… Read More »
You are given a list of positive numbers. In this list, each integer denotes the maximum number of jumps that you are able to make from that integer’s index to the forward direction. You need to determine the minimum number of jumps that you can make starting from the initial 0th index so that you can reach the… Read More »
Docker achieves isolation of containers by using some of the Linux kernel features called cgroups and namespaces and applies them to containers. But what if we have multiple containers and we want them to communicate with each other. For instance, suppose we have a frontend app and a backend app along with a message queue which must be… Read More »
Docker is a free and open-source platform that can be used for building, delivering, and running applications in an isolated environment. Docker allows you to decouple your code from your hardware, allowing you to easily deploy and share apps. One of the highlighting features of docker is that we can run multiple docker environments in the same host… Read More »
A Docker container can be used to isolate applications from the host machine. This isolation is based on kernel namespaces and cgroups, all of which have been used for a long time in Linux. When we execute the docker run command on an image, it creates a container associated with that image. A writeable layer is stacked on… Read More »
A Docker image is a multi-layered file used to define the environment in a Docker container. An image is a series of instructions for creating a fully functional and isolated environment for running applications that runs on the kernel of the host operating system. One or more instances of an image are created when a Docker user runs… Read More »
Previously, if you were to run a web server, you had to either set up a Virtual Machine on your own or find a physical server elsewhere. This is often referred to as “bare-metal” because the code is actually running on the processor with no abstraction. This is ideal if you need high efficiency and have a large… Read More »
A Docker image is a read-only template that includes instructions for building a Docker container. It gives you a simple way to package up the application and also provides pre-configured cloud environments that you can share privately or publicly with other Docker users. In this article, we are going to look at some of the most common and… Read More »
Docker storage drivers allow us to provide facilities for managing and storing images, containers, and other Docker objects efficiently on the Docker host machine. They are also termed as Graph Drivers. The Docker uses a pluggable architecture that allows them to support multiple storage drivers. Storage drivers provide ways through which we can write our workloads to the… Read More »
If your application has simple requirements, then it might be feasible to develop and deploy the application in a single Docker container. However, when traffic continues to grow, you might want to scale up your application so that system failure due to overload does not happen. In such a case, you might want to deploy your application as… Read More »
