Spring Boot & Microservices

Spring Boot Reactive Programming
Spring Boot Reactive Programming is a programming paradigm that allows developers to build non-blocking, asynchronous applications using the Spring Boot framework. It leverages the reactive programming model to handle data streams and events, enabling efficient resource utilization and improved scalability.

DevOps

Docker is an open-source containerization software that enables developers to build, ship, and run applications using containers. Containers are lightweight, isolated environments that bundle an application with all its dependencies, ensuring it runs consistently across different environments.
Docker Commands
Docker commands are the instructions used to interact with Docker, a popular containerization platform. These commands allow users to manage containers, images, networks, and volumes, enabling efficient application deployment and management.
Jenkins CI/CD with Docker
Jenkins is one of the most popular open-source automation tools for building, testing, and deploying applications. When combined with Docker, Jenkins becomes even more powerful, enabling consistent, isolated, and scalable CI/CD (Continuous Integration and Continuous Deployment) pipelines.
Kubernetes is an open-source container orchestration platform designed to automate the deployment, scaling, and management of containerized applications. It provides a robust framework for running distributed systems resiliently, allowing for load balancing, self-healing, and automated rollouts and rollbacks.

AWS

AWS Account Setup
Setting up an AWS account is the first step to accessing Amazon Web Services. This process involves creating an account, verifying your identity, and selecting a payment method. Once set up, you can access a wide range of cloud services and resources.
EC2 Instance Setup
Setting up an EC2 (Elastic Compute Cloud) instance on AWS allows you to launch virtual servers in the cloud. This process includes selecting an Amazon Machine Image (AMI), choosing instance types, configuring security groups, and launching the instance.
Connect to EC2 using MobaXterm
Connecting to an EC2 instance using MobaXterm involves using the SSH protocol to establish a secure connection. MobaXterm provides a user-friendly interface for managing SSH sessions, file transfers, and remote command execution.
Connect to EC2 using PuTTY
Connecting to an EC2 instance using PuTTY involves converting the private key file (.pem) to a PuTTY-compatible format (.ppk) and then using PuTTY to establish a secure SSH connection to the instance.

Software Architect

Model in Software Development
In software development, a model is a simplified representation of a system or process. Models help in understanding, designing, and analyzing software systems. They can be visual, mathematical, or conceptual and are used to communicate ideas and requirements among stakeholders.
UML (Unified Modeling Language) is a standardized modeling language used in software engineering to visualize, specify, construct, and document the artifacts of a software system. It provides a set of graphical notation techniques to create abstract models of specific systems.
An Entity-Relationship (ER) model is a high-level conceptual data model that defines the structure of a database. It uses entities (objects) and relationships to represent data and its relationships, providing a clear visual representation of the data requirements.
System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It involves creating a blueprint for the system, ensuring it meets both functional and non-functional requirements.

Linux

Linux Text Editors
Linux offers a variety of text editors, ranging from lightweight terminal tools to full-featured graphical IDEs. Each serves different needs, whether you're editing config files, writing code, or creating documentation.

Signs You're a Real Software Developer

Developer Roles & Responsibility
A software developer is a professional who creates software applications, systems, or platforms. They are responsible for the entire software development lifecycle, from gathering requirements and designing solutions to coding, testing, and deploying software.
Real-Time Application Environments
Real-time application environments are systems that process data and provide immediate feedback or results. They are crucial in scenarios where timing is critical, such as in embedded systems, telecommunications, and financial trading platforms.
Teams in a Real-Time Application Environment
In a real-time application environment, teams are structured to ensure efficient development, deployment, and maintenance of applications. These teams often include roles such as developers, testers, DevOps engineers, product managers, and system architects.
