Reasons Why DevOps Adoption Might Be of Help for Business

Posted: 31 May 2022 11:22 AM PDT

As far as this modern and tech-oriented IT domain goes, DevOps has become a standard to judge operations' overall efficiency and smoothness. However, like it is with everything in the world, there is still a sizeable chunk of enterprises in the process of either understanding what it means or completely not being aware of it at all.

In this post, we will try to cover a few crucial points that will include a brief overview of DevOps and why DevOps adoption might be helpful for businesses.

Functional vs. Non-functional Testing: Can You Have One Without the Other?

Posted: 31 May 2022 10:44 AM PDT

Functional and non-functional tests are the most popular approach to categorizing the different types of software testing. These two categories refer to the very essence of the testing process and what exactly is being tested. There are two things to know about functional and non-functional testing if you've never dug deep into these two testing categories before. 

One, the division between non-functional and functional testing is not set in stone, and for some testing types, categorizing them is no easy feat. Two, both functional and non-functional testing are essential for the success of your software testing project, albeit in different ways. Today, we will take a closer look at the difference between functional and non-functional requirements, where these two types of testing stand in the software testing process, and how they influence the cost of testing.

How to Perform Visual Regression Testing Using Playwright

Posted: 31 May 2022 08:21 AM PDT

Regression testing verifies that system changes do not interfere with existing features or code structure. They are part of almost every test suite in software development lifecycles. It is common for developers to change or add a code section and unintentionally disrupt something that is working just fine.

Visual regression testing functions on the same logic but confines it to the visual aspects of the software. It works by comparing two images and automating complicated scenarios, like when we cannot identify the elements in the DOM tree. However, visual regression can be used on any website.

Creating an Event-Driven Architecture in a Microservices Setting

Posted: 31 May 2022 07:37 AM PDT

Event-driven-based architectures and microservices are both known to improve agility and scalability in systems. Event-driven architectures decouple the producer and consumer of the data, while microservices are a modern service-oriented architecture.

But can these two architectures co-exist?

AWS Lambda Basics: Writing Serverless Code

Posted: 31 May 2022 07:29 AM PDT

Introduction

There are four key capabilities necessary for a service or platform to be serverless:

  • No server management
  • Flexible scaling
  • High availability (fault tolerance)
  • No idle capacity

In this post, we will learn the basics of AWS Lambda and how you can use it for different use cases with ease. This will be an introduction post that can provide a foundation for upcoming demos and posts to help you learn AWS.

Web Performance Testing — What, Why, How of Core Web Vitals

Posted: 31 May 2022 07:08 AM PDT

A website needs to be constantly tested and optimized to be in line with Google's web and SEO guidelines. As a result, it has an advantage over others in terms of visibility, brand image, and driving traffic. However, to tactically assess the website's performance, it needs to be measured in a well-thought-out manner. Core Web Vitals is a key performance metric that analyzes the website's performance by investigating the data and provides a strategic platform to scale up the website's user experience. This article will learn about web performance testing and how Core Web Vitals plays a crucial and strategic part in it.

What Is Web Performance Testing?

Web performance testing is executed, so that accurate information is provided on the application's readiness by monitoring the server-side application and testing the website. This is done by simulating a load that is in line with real conditions so that the expected load can be supported by the application that has been evaluated. 

Setting Up a Dedicated Database Server on Raspberry Pi

Posted: 31 May 2022 05:18 AM PDT

There is certain gratification when you get a little "naked" mini-computer board to run the software you install on it. Maybe even your own application. Most (if not all) of the real-world applications I have implemented connect in one way or another to a database. It's not a secret that relational databases are the most popular option in mission-critical applications that require truly ACID compliance. So, installing a good performant SQL database in a Raspberry Pi is, to say the least, a fun exercise to do. Even though the Raspberry Pi can connect to the Internet and consume a Database as a Service (DBaaS) like SkySQL, smaller applications might benefit from having a local-only database running on the same device.

In this article, I show you how to install and set up a MariaDB server on a Raspberry Pi 4 Model B with 8 GB of RAM that you can connect to your local network through WiFi or Ethernet. You can use models with much less RAM memory as well.

What Makes "Minimum" in Minimum Viable Product?

Posted: 31 May 2022 04:52 AM PDT

What Is an MVP?

The Minimum Viable Product (MVP) is a product without any additional features and, at the same time, comes with all the essential features that users want.

Think of it as a test drive. It is a lean, agile model that allows you to maximize learning about your business with minimal development effort and the shortest possible time, resource, and cost commitment.
Unlike a prototype or the traditional business model canvas, which are usually created once the idea generation stage of one's startup is finished, the
