We are living in a world where the internet is an inseparable part of our lives, and with the growth of Cloud computing and increased demand for AI/ML-based applications, the demand for network capacity is unstoppable. As networks scale exponentially, classical topologies and designs are struggling to keep in sync with the rapidly evolving demands of the modern IT infrastructure. Network management is getting complex due to the sheer amount of network infrastructure and links. AI-driven intent-based networking emerges as a potential solution, promising to reshape our approach to network management — but is it truly the solution to this problem it claims to be? Let’s dive into its details to understand how intent-based networking will be shaping the future of network management. What Is Intent-Based Networking? Traditional intent-based networking (IBN) evolved from software-defined networking (SDN). SDN is a very popular approach in network automation where software-defined controllers and APIs communicate with the physical Infrastructure. IBN is a natural progression of SDN that combines intelligence, analytics, machine learning, and orchestration to automate network management. It translates high-level business intent into network policies to configure the underlying network. IBN abstracts the complex part of underlying hardware, and network configuration to allow users to express their desired intent in natural language. 

From data ingestion to reporting, the primary goal is to convert data into actionable information. Online data is growing at a much faster rate than data processing speeds. For businesses to stay competitive, data must be readily available for making informed decisions as early as possible. Live data streaming software is becoming a vital part of data infrastructures to get data to processing systems as early as possible. While different streaming software are available, it is crucial to understand the domain context and available infrastructure. Each business use case is unique and should be treated with white-glove treatment. The critical thing to remember is that cheap, fast, and good will never make a feasible combination. The affordable solution may be quick but not good; a fast solution may be good but not cheap, and so on. An ideal example of this concept would be real-time streaming data processing. 

In today’s digital world, where automation and scripting are essential for developers, security remains a paramount concern. One of the simplest ways to install developer tools is through scripts downloaded directly from the internet. However, this convenience also comes with inherent risks, especially when dealing with external sources. Web3j is a security-focused project. It has taken steps to reduce risks from running installer scripts. This includes protecting against remote code execution (RCE) threats.

In this article, I aim to discuss modern approaches used to reduce the time required to establish a data transmission channel between two nodes. I will be examining both plain TCP and TLS-over-TCP.  What Is a Handshake? First, let’s define what a handshake is, and for that, an illustration of the TCP handshake serves very well:

The venerable Raspberry Pi has been around for over a decade (officially created in 2009) and it has become a standard in many robotics, home automation, and other types of uses, especially for “makers” and other tinkerers. But it has also made serious inroads into the professional and enterprise world — just more quietly. It’s a capable, reliable, and powerful single-board computer (SBC) with a robust user community. For all its strengths, it does have a few notable weaknesses. The biggest one is security. Not because the SBC itself is insecure, and not because the Operating System (OS) is insecure (it runs Linux, which can be very well secured). The most vulnerable part of the Raspberry Pi is the fact that it boots and runs off of a micro SD card.

Ethereum addresses, with their 42 characters, have become a hallmark of the web3 ecosystem. However, memorizing these long strings is nearly impossible for most users. The Ethereum Name Service (ENS) addresses this issue by offering a decentralized naming protocol on the Ethereum blockchain.
