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
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
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 Model
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.
ER Model
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
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.
