VPN allows for secure communication over public networks through tunneling protocols like PPTP, L2TP, and IPsec. There are three main types of VPN implementations: intranet within an organization, extranet between an organization and outside users, and remote access for mobile users. VPNs provide advantages like reducing costs of long-distance lines and charges while allowing flexibility and efficiency. However, they also have disadvantages like requiring expertise in security issues and performance depending on external factors. Industries like healthcare, manufacturing, retail, and banking commonly use VPNs to securely transfer private information between locations.

Virtual Private Networks (VPN) allow secure connections over public networks like the Internet. VPNs use encryption to create "virtual private tunnels" between devices. This allows remote users to access resources on a private network as if they were directly connected. There are two main types - remote access VPNs for individual users and site-to-site VPNs to connect multiple office locations. VPNs work by encapsulating data packets within encrypted "tunnels" to securely transmit them between endpoints across public networks while maintaining privacy and security.
Vpn(virtual private network)
VPN extends a private network over a public network like the internet and enables secure communication. VPN uses tunneling to encapsulate private network traffic within public network traffic to pass securely. There are two main types of VPN - remote access VPN allows users to remotely access a private network, while site-to-site VPN connects multiple office networks. VPN security is achieved using protocols like IPSec, L2TP, PPTP that encrypt data and authenticate users to establish secure tunnels between VPN devices.
VPN, Its Types,VPN Protocols,Configuration and Benefits
VPN allows users to securely connect to private networks over the internet. There are two main types of VPNs: remote access VPNs that allow users to access private networks remotely, and site-to-site VPNs that connect networks of different office locations. VPNs use various protocols like IPsec, L2TP, PPTP, OpenVPN, SSL/TLS, and SSH to encrypt data transmission and establish secure tunnels between devices. VPNs provide benefits such as accessing blocked websites, more secure online activity, protecting public WiFi connections, and allowing remote access to private networks.

VPN - Virtual Private Network
Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.

Network types & its topology
Networking connects two or more computers to share resources. It involves client computers that access shared resources from server computers via communication links and network interface cards. Common network types include personal area networks (PANs) for connecting devices near a single user, local area networks (LANs) for connecting devices within an office or building, and wide area networks (WANs) for connecting sites over long distances. Network topologies determine how devices are arranged and connected in a network.

A VPN or Virtual Private Network is a service that adds security and privacy to private and public networks by creating an encrypted tunnel between devices. It verifies authentication between two hosts and encrypts data so outsiders cannot see it. VPNs allow users to securely connect to private networks remotely and bypass internet censorship while hiding their actual location by providing an alternative IP address. There are two main types of VPNs: remote access VPNs which allow users to remotely access private networks, and site-to-site VPNs which connect the networks of multiple office locations for companies.

It describes the main types of VPNs: remote access, intranet, and extranet. Remote access VPNs allow mobile users to connect to an organization's network. Intranet VPNs connect organization offices over the internet. Extranet VPNs are similar but connect external users like customers or suppliers. The document also discusses tunneling, which encapsulates data packets for transmission, and lists some advantages and disadvantages of using VPNs.
Virtual Private Network
A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.
IRJET- A Survey of Working on Virtual Private Networks
This document provides an overview of virtual private networks (VPNs). It discusses VPN architecture, including remote access VPNs that allow single users to connect from remote locations, and site-to-site VPNs that connect two private networks. The document explains how VPNs work by encrypting data packets and encapsulating them within IP packets to allow transmission over the public internet in a secure manner. Key advantages of VPNs are lower costs compared to leased lines and scalability to connect multiple office locations.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
