Distributed Tracing: A Full Guide

What Is Distributed Tracing?
The rise of microservices has enabled users to create distributed applications that consist of modular services rather than a single functional unit. This modularity makes testing and deployment easier while preventing a single point of failure with the application.
While applications begin to scale and distribute their resources amongst multiple cloud-native services, tracing a single transaction becomes tedious and nearly impossible. Hence, developers need to apply distributed tracing techniques.

Security Architecture Review on a SASE Solution

Vendor security assessments can be very complex, especially when it comes to analyzing modern solutions. Obsolete threat modeling principles and frameworks become extremely unreliable and tricky as complexity increases. Security analysis also becomes further intricate as it is not limited to the application’s inherent design but also how it is integrated with any organization’s core network. Implementation and configuration induces vulnerabilities in the system if security is not a part of the development lifecycle. Recent trends suggest that organizations are now moving to SASE solutions, replacing existing vendors that provide services like CASB (Cloud access security broker), DLP (Data Loss Prevention), proxy solutions, etc.
What is SASE?
Secure Access Service Edge (SASE) is a framework that provides network convergence alongside security services. It adds security to the ingress and egress network traffic. The technology stack usually comprises CASB, DLP, SWG (Secure Web Gateway), FWaaS (Firewall as a Service), NGFW (Network Firewall), SDN (Software Defined Networking), and ZTNA (Zero Trust Network Architecture) solutions. 

There’s a Better Way To Deploy Code: Let’s Share It

Gatekeeping best practices within the developer community benefits no one. If there’s a better way to deploy code, we should share it. Why? Because a developer community is just that: a community. What benefits one team will help another, creating more efficient processes, reducing hassle, and elevating software quality and performance across the board. We are witnessing increased collaboration in the DevOps space, a trend we should encourage.
What Is Gatekeeping?
Senior developers have learned many lessons over the course of their careers, and many developed innovative solutions to development cycle challenges. In the past, they may not have openly shared their experience and knowledge; whether it was intentional or not, they were essentially gatekeeping their practices.

Rest API vs GraphQL

REST, or Representational State Transfer, is an architectural style for building web services that use HTTP requests to access and manipulate data. REST APIs are widely used and understood by developers, making it a popular choice for building web services. On the other hand, GraphQL is a query language for APIs that was developed by Facebook. It allows clients to specify the structure of the data that they require and receives the exact data that they request.
Let’s take a closer look at some of the pros and cons of using GraphQL and REST.

5 Challenges Every Engineering Manager Must Overcome

Transitioning to a managerial role could be hard. One day, you are developing and reviewing code. The next day, you are handling not just individuals but a multitude of teams, evolving into a people person and leading your squad toward maximum productivity. Each engineering manager is different, and so are their roles, responsibilities, and ideas to better their teams. However, across the spectrum, here are the common challenges every engineering manager faces as they step up their software journey.
What Does an Engineering Manager Do?
Apart from what an EM’s JD says, the ultimate goal of the position is the same throughout: helping devs become masters of their work. However, as a manager, the results and work items are not as tangible as an engineer’s. An EM ideally spends time leading retros, mentoring, and managing the well-being of team members. It is not easy to create a direct commit log for managers, much like engineers. Yet, there are some common grounds for most engineering managers across three categories: 

React, Angular, and Vue.js: What’s the Technical Difference?

React, Angular, and Vue.js are three popular JavaScript frameworks used for building complex, single-page web applications. While they all have a common goal, they differ in various ways. In this article, we will take a closer look at the differences between React, Angular, and Vue.js. 
React is a JavaScript library for building user interfaces. It was created by Facebook and is maintained by Facebook and a community of developers. React is based on the idea of component-based architecture, where a web page is built as a collection of small, reusable components. React is known for its simplicity and flexibility, making it easy to learn and use.

How SecDevOps Adoption Can Help Save Costs in Software Development

Security in software development is a critical issue that is often addressed late in the software development process (SDLC). However, with the increasing demand for secure applications and systems, integrating security into all stages of the SDLC has become essential. This is where SecDevOps comes into play, an approach that combines DevOps culture, processes, and tools with security.
What Is SecDevOps?
SecDevOps is a collaboration between development, operations, and security teams to integrate security into all stages of the SDLC. This allows security issues to be quickly detected and fixed before software is released to the market. 

When to Use Decision Trees vs. Random Forests in Machine Learning

The development of sophisticated algorithms has Completely changed how data is handled and choices are made. With so much online data, efficient interpretation and decision-making tools have become essential. Choosing the best option can be difficult, though, because so many options are accessible. The ideas behind decision trees and random forest algorithms will be covered in this blog, along with comparing the two. We will also look at the benefits of random forests versus choice trees.
A decision tree is a model that divides the data recursively according to the values of its features to forecast a target variable using a tree-like structure. To produce an exact tree that is simple to understand and helpful for making decisions, the algorithm chooses the features that offer the most significant information gain or the best split.

Correlations Made Easy

In the connected world, the internet and social networks give an additional push to generate humongous data. There is no such great challenge to store all the data that was generated, and one can leverage the latest advancements in terms of storing data. The real challenge is to understand and identify the possibility to correlate this data and draw meaningful insights. In this article, we will check out in more detail correlations and how to identify the correlation coefficient between given variables.
Data Analytics
Data Analytics plays a key role in deep diving into data, identifying trends, discovering data patterns, and extracting value out of data. Here, I would like to give a real-time example instead of regular correlation examples (sales of umbrellas during rainstorms and sales of ice cream during summer). The two variables we consider here to correlate are:
