AWS networking can feel like a maze, but once you get the basics down, it’s actually pretty straightforward. If you’ve ever wondered how AWS connects everything - from the internet to your data centre, remote workers, and internal AWS services - this breakdown is for you.
- VPC (Virtual Private Cloud) - Your own private slice of AWS, where you control the networking.
- Availability Zones (AZs) - Physically separate data centres in an AWS region, designed for redundancy and high availability.
Allows your AWS resources to send and receive traffic from the internet. Essential for public-facing applications.
Lets employees securely connect to your AWS network from anywhere, just like they would in the office.
Used for setting up a Site-to-Site VPN, so your corporate network can securely communicate with AWS.
Enables private communication between two VPCs, avoiding the public internet altogether.
If you’ve got multiple VPCs and accounts, Transit Gateway acts as a central router, simplifying the connections between them.
Allows your VPC to privately connect to AWS services like S3 and DynamoDB, without needing an internet gateway or VPN.
Provides private connections between your VPC and AWS services without exposing traffic to the public internet.
Lets you privately connect your VPC to SaaS applications running on AWS, without traffic going through the internet

In this way, the process that starts with a developer 'pushing' code to GitHub goes through stages of automated webhook triggering, continuous delivery,
Docker image creation, and container deployment.
All these steps are automated to minimize manual errors and speed up the process.

When exposing applications in Kubernetes, should you use a Load Balancer or an Ingress Controller?
A Load Balancer distributes external traffic to Kubernetes services at the network layer (L4 – TCP/UDP). Cloud providers (AWS, Azure, GCP) provision external load balancers when a Service type is set to LoadBalancer.
When to Use a Load Balancer?
Benefit 👇
An Ingress Controller manages HTTP(S) traffic at the application layer (L7), routing requests based on hostnames, paths, and SSL/TLS termination. It exposes multiple services via a single entry point using an Ingress resource.
When to Use an Ingress Controller?

What is Ansible →
➡️ Ansible is DevOps tool and it is similar like chef means it is a Configuration management tool let’s Begins with a Story → suppose you have a big organisation which have 100’s of servers Now a task is came to install git on that 100’s of servers …man responsible for doing this is System Administrator who is doing this manually which takes a lot of time…
guys!!!! we have that tool and that is Ansible→ A Configuration Management Tool…..
➡️ But !! But !! But !! First you need to connect all the nodes to ansible server which is done manually after that you will be able to automate the things…..
➡️ configuration management →It is a method through which we automate admin tasks.
➡️ It automates the task which the system administrator doing manually
Configuration management tool is of 2 types →
➡️ Pull based → In Pull Based it periodically check for the update from the main server to the nodes if update available it automatically install on the nodes connected with the server → chef and puppet is a pull based config tool.
➡️ Push based → In push based nodes is not going to the main server for the update the update is pushed to the nodes automatically for example the update of apps is pushed to your phone play store now it’s your choice whether you update or not → push based tool is Ansible when you need control in your hands so you take control of your own server for updating.
History of Ansible →
➡️ Michael Dehan developed Ansible in Feb 2012
➡️ Red Hat acquired the Ansible tool in 2015.
➡️ Ansible is available for RHEL, Debian, cent OS, Oracle Linux.
➡️ It is developed in Python background and also in Windows PowerShell.
➡️ You Can use this tool whether your server are in on premises or in the cloud.
➡️ It converted your code into infrastructure means you can say that it is a little bit called an Infrastructure building tool.

- DevSecOps is the approach of blending development, security, and operations in a single, continuous pipeline.
- By integrating security into every stage of the development lifecycle, DevSecOps minimizes the risk of security breaches while maintaining agility.
Develop:
Write and maintain code, embedding security practices early.
Build:
Compile code into artifacts with automated security scans.
Test:
Validate functionality and security through automated tests.
Deploy:
Release applications securely with automated checks.
Monitor:
Continuously observe performance and security to respond to incidents.
Design:
Architect applications with security in mind, integrating secure coding practices.
DevSecOps comes with a wide range of benefits that not only improve security but also enhance overall efficiency:
Continuous integration of security practices helps detect vulnerabilities early, reducing the chances of attacks.
Automation streamlines development, security checks, and operations, speeding up the entire delivery process.
Developers, security experts, and operations teams work closely, improving communication and collaboration across the board.
Automated security checks ensure the application complies with industry standards and regulations without slowing down development.
Catching and fixing security flaws early in development reduces the cost of resolving them later in production.
Adopting best practices ensures the smooth functioning of the DevSecOps pipeline:
- Leverage automation for code scans, vulnerability checks, and configuration validation. Tools like Jenkins, GitLab CI, and others streamline this process.
- Implement constant security monitoring to detect and address potential threats in real-time using tools like ELK Stack or Prometheus.
- Security testing is performed early in the pipeline, ensuring that vulnerabilities are caught as soon as possible.
- Ensure that automated incident response workflows are in place to swiftly counter security breaches and minimize downtime.
