Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud, offering over 200 fully featured services from data centers globally. Among these hundreds of services, we require only a select few known as “core services,” which assist us in hosting our entire tech stack. As depicted in…

Overview In a given scenario, one AWS resource is attempting to access, create, or modify another AWS resource. For instance, as depicted in the image below, three EC2 instances (AWS resources) are attempting to access an S3 bucket (another AWS resource). IAM Role An IAM Role is similar to the IAM user…

Overview During the program execution, at what stage CPU registers came into picture while performing computation on our program? As we all know our code is compile from plain English/human-readable language to machine code. This machine code consists primarily of CPU instructions, not data. CPU instructions are the low-level commands that…

Containerization has revolutionized the way we deploy and manage applications, and Linux is at the heart of this transformation. As developers, we often encounter a plethora of Linux commands that are essential to understanding and working with containers. In this series of articles, we’ll explore some of the most important…

Network interfaces are hardware or virtual components that allow a system to connect to a network. These interfaces can be physical, such as Ethernet or wireless adapters, or virtual, such as loopback interfaces(l0). Each network interface has a unique name, such as eth0 or wlan0, and is identified by a unique MAC (Media Access Control) address. The MAC address is a unique identifier assigned to each network interface by the manufacturer.

Networking is an essential aspect of modern computing, enabling devices to communicate and share information with each other over a network. Encapsulation is a critical concept in networking that involves the wrapping of data and information within a protocol-specific header and footer. This process allows data to be transmitted across…

When learning Kubernetes, you may have wondered why there is an extra layer on top of containers, namely Pods. In the image below, there are four containers grouped into three sets (which are called Pods). In the initial stages of our Kubernetes learning journey, we typically consider Pods with a…

This article is a step by step guide for “what steps should be taken care before using virtual machines on a windows laptop”. Here are the following steps:- First, we need to enable Hardware virtualization. This is a feature that allows the processor to run multiple virtual machines (VMs) at…

Cluster of container means a bunch of container are working together to provide the result. Some of the popular tools for container clustering tools are as follows and these tools behave like an orchestrator. Docker SWAM Kubernetes Before going into deep and try to understand these tools we should…
