Alpha Testing Tutorial: A Comprehensive Guide With Best Practices

Alpha testing is a procedure that helps developers find and address faults in their software products. It is comparable to user acceptance testing, another kind of quality control. The main goal of the Alpha test is to fine-tune a software product by uncovering and fixing faults that were not addressed during the initial phases of development.
While developing new software applications, many organizations overlook conducting Alpha tests. It focuses on particular product areas to detect and correct flaws missed during software development.

Comparing Cloud Hosting vs. Self Hosting

You just utilized several cloud-based applications to access this content, whether you’re reading it on a desktop or smartphone. Cloud hosting vs. self-hosting is two well-known software applications that will be the focus of this article.
Cloud Hosting 
This is the process of hosting websites, programs, or other computing resources on virtual servers that a cloud service provider provides and manages. Cloud hosting uses a network of connected servers, frequently dispersed over various data centers or geographical locations, as opposed to relying on a single physical server.

Data Freshness: Definition, Alerts To Use, and Other Best Practices

Data freshness, sometimes referred to as data timeliness, is the frequency with which data is updated for consumption. It is an important dimension of data quality because recently refreshed data is more accurate and, thus, more valuable.
Since it is impractical and expensive to have all data refreshed on a near real-time basis, data engineers ingest and process most analytical data in batches with pipelines designed to update specific data sets at a similar frequency in which they are consumed. 

Micro Frontends on Monorepo With Remote State Management

Almost every third enterprise company has a large monolithic application that takes a lot of effort to develop and support. Many teams and frontends cause many problems and confusion in the development process. For the second year in a row, the code structuring architecture pattern — micro frontends — has been gaining increasing popularity.
This article will see all aspects of micro frontends, like structure, remote state management, and module federation plugin usage.

Test Data Tutorial: A Comprehensive Guide With Examples and Best Practices

The test data is similar to the production data used by test cases when testing software applications. It is typically collected in the test data document used by test cases and scripts. Unless test data is designed in advance, test cases may not cover all scenarios and ultimately impact software quality.
As software applications become more complicated and testing more rigorous, the amount of test data being ingested by testers has increased exponentially during the information and technology revolution.

What Is React? A Complete Guide

React is a popular JavaScript library for web development, preferred for building reusable UI components. This comprehensive guide covers all aspects of React for both experienced and beginner developers.
Introduction To React
In 2013, Facebook software engineer Jordan Walke introduced React as an in-house solution for constructing user interfaces. It gained popularity and was later released as an open-source library.

Scaling Site Reliability Engineering (SRE) Teams the Right Way

Most SRE teams eventually reach a point in their existence where they appear unable to meet all the demands placed upon them. This is when these teams may need to scale. However, it’s important to understand that increasing team capacity is not the same as increasing the number of people on the team. Let’s unpack what scaling a team is all about, what are the indicators, what are steps you can take, and how you know if you’re done.
Scaling Triggers
Sometimes it is very easy to tell whether you need to scale your team or not. For example:

Implementing a Serverless DevOps Pipeline With AWS Lambda and CodePipeline

AWS Lambda is a popular serverless platform that allows developers to run code without provisioning or managing servers. In this article, we will discuss how to implement a serverless DevOps pipeline using AWS Lambda and CodePipeline.
What Is AWS Lambda?
AWS Lambda is a computing service that runs code in response to events and automatically scales to meet the demand of the application. Lambda supports several programming languages, including Node.js, Python, Java, Go, and C#. CodePipeline is a continuous delivery service that automates the build, test, and deployment of applications. CodePipeline integrates seamlessly with other AWS services, such as CodeCommit, CodeBuild, CodeDeploy, and Lambda.

Automated Multi-Repo IBM App Connect Enterprise BAR Builds

The IBM App Connect Enterprise (ACE) toolkit has long been used for application development and also for building BAR files to be deployed to integration nodes, with the IDE’s capabilities making it relatively simple to work with applications and libraries contained in multiple source repositories. The toolkit is not easily automated as such, however, and it may appear that the source layout must be reorganized before automation is possible: the command-line build tools lack some of the toolkit’s project-handling capabilities and therefore present some challenges when working with complex source environments. Despite the challenges, this article shows an alternative to reorganization, with relatively little work being needed to allow for automation to proceed.
Quick summary: The toolkit presents a virtual filesystem based on projects, and the command-line equivalent is to fix up the extracted source during a build; a working example is shown below.

Mainframe Development for the “No Mainframe” Generation

Powerful but Unknown
Few people will recognize a mainframe as a modern digital environment, but in fact, it is a widely used powerful platform. When shopping or doing your taxes, there is probably a mainframe involved at some point. As a developer, you are likely to “encounter” one during your career, even if you are not actually dealing with “green screens.” However, without mainframe knowledge, how do you proceed? Someone once said: “All the people with relevant knowledge are dead or retired.” Even though that is not entirely true, learning how to “handle” the mainframe could indeed pose difficulties.
Mainframe in a Laboratory
One of the software development departments at the Dutch IT company Ordina is involved in mainframe technology. Apart from mainframe development, it focuses on three points:
