Aggregated on: Tue Jun 13 2023 22:30:50 GMT+0000 (Coordinated Universal Time)

In previous articles, Spring Cloud: How to Deal with Microservice Configuration (Part 1) and Spring Cloud: How to Deal with Microservice Configuration (Part 2), we have seen how to deal with microservices remote configuration. In this post, we are going to talk about another important feature in the context of microservices, namely Service Discovery. Service Discovery plays the role of a central registry in which all the services store their metadata information and from which they can get the metadata of other services. The service discovery feature is implemented by a server and a corresponding client counterpart. In this article, we are going to describe how to configure a discovery server and make the client services able to reach it and use it. We will also see how to set a configuration based on the so-called "zone affinity."

Everything Bad in Java Is Good for You

Aggregated on: Tue Jun 13 2023 22:15:50 GMT+0000 (Coordinated Universal Time)

Everything Bad is Good for You is a pop culture book that points out that some things we assume are bad (like TV) have tremendous benefits to our well-being. I love the premise of disrupting the conventional narrative and was reminded of that constantly when debating some of the more controversial features and problems in Java. It’s a feature, not a bug… One of my favourite things about Java is its tendency to move slowly and deliberately. It doesn’t give us what we want right away. The Java team understands the requirements and looks at the other implementations, then learns from them.

Making the Leap From Old-School Monitoring to Modern O11y

Aggregated on: Mon Jun 12 2023 18:45:50 GMT+0000 (Coordinated Universal Time)

The term "old-school" has two decidedly different meanings. On the one hand, it can mean classically trendy, something that never went (or will go) out of style. On the other, it connotes something that's outdated, outmoded, and fairly irrelevant. I cut my teeth on ping and SNMP, so — while it pains me to say this — old-school monitoring is decidedly in the latter category. Back in the day, if the experience your company was providing, I’ll call this a service, could be measured, it was not easy to do. You were left trying to infer user experience based on data from parts of the service as a whole. It included measuring CPU, RAM, and database metrics and hoping that those metrics reflected enough to tell whether your service was truly working for your customers. With this “old school” way of thinking, enough tangential insight could add up to a full picture of a user's actual experience.

Strengthening Your Web App Security: Preventing SQL Injections

Aggregated on: Mon Jun 12 2023 14:30:50 GMT+0000 (Coordinated Universal Time)

The database plays a vital role in a web application as it stores and organizes its data. It serves as a central repository for storing user information, content, and other application data. The database enables efficient data retrieval, manipulation, and management, allowing the web application to deliver dynamic and personalized content to users. However, poorly implemented communication between a database and a web application can lead to sensitive data breaches, users' mistrust, legal consequences, and loss of profits. In this article, we'll explore backend misconfigurations that lead to such disasters and learn how to ensure the application's safety. What Is SQL Injection? SQL Injection – or SQLi – is a vulnerability that allows an attacker to tamper with queries that web applications send to the database. Injection occurs when an application misinterprets users' input and treats it as SQL code rather than a string. As a result, malicious users can change the intended query flow, subvert the application's logic, and gain unauthorized access to its resources.

Software Testing: An Art of Providing Superior Quality Economically

Aggregated on: Mon Jun 12 2023 13:45:50 GMT+0000 (Coordinated Universal Time)

Software testing is the demonstration of looking at the relics and the way the product behaves under test by approval and check. A business can appreciate and comprehend the risks of implementing software by receiving an objective, independent view of the software through software testing. Although it is possible to determine the correctness of software by assuming certain hypotheses, software testing cannot identify all software failures. Instead, it provides a critique or comparison that compares the state and behavior of the product to test oracles, which are principles or mechanisms by which a person might recognize a problem. Specifications, contracts, comparable products, previous versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, applicable laws, or other criteria are all examples of these oracles. This highlights the significance of QA testing companies.

The Unified Principles of Methodologies

Aggregated on: Fri Jun 09 2023 15:45:48 GMT+0000 (Coordinated Universal Time)

In the realm of project management and software development, various methodologies have emerged, including Six Sigma (Define, Measure, Analyze, Improve, Control — DMAIC), Agile, FMEA, Scrum, Kanban, Extreme Programming (XP), and Feature-Driven Development (FDD). While proponents of each methodology often emphasize their uniqueness, a closer examination reveals that these methodologies share underlying principles and that the perceived disparities are often mere illusions. This article aims to explore the philosophical foundations that bind these methodologies, demonstrating that their variations serve primarily to perpetuate the belief in novelty. By uncovering their common principles, we can foster a deeper understanding and promote collaboration across these approaches. The Pursuit of Excellence: The Telos of Methodologies At the heart of all these methodologies lies the pursuit of excellence. Ancient philosophers such as Plato and Aristotle contemplated the notion of telos, the inherent purpose or goal of a thing. Similarly, these methodologies seek to improve processes, optimize outcomes, and achieve excellence in their respective domains. They share the recognition that constant refinement and the pursuit of perfection are crucial for success. Epistemology: The Foundation of Knowledge Epistemology, the branch of philosophy concerned with the nature of knowledge, plays a vital role in these methodologies. They acknowledge that knowledge forms the bedrock upon which improvement is built. From John Locke's empiricism to Immanuel Kant's transcendental idealism, philosophers have explored different avenues to understand how we acquire knowledge and apply it to the world. Similarly, methodologies like Six Sigma (DMAIC), Agile, FMEA, Scrum, Kanban, XP, and FDD emphasize the value of data-driven decision-making, continuous learning, and leveraging insights from experience. They recognize that knowledge is dynamic and ever-evolving, driving progress and innovation.

Introduction to API Gateway in Microservices Architecture

Aggregated on: Thu Jun 08 2023 17:00:47 GMT+0000 (Coordinated Universal Time)

Some architects, cloud engineers, and DevOps folks often say, “Microservices are small monoliths.” This stems from the complexity of dealing with a number of services, especially managing and configuring their network rules and security aspects. When clients make requests to microservices spread over multiple clusters and clouds in a distributed system, tracking each request to ensure security and proper routing rules becomes tedious. Ideally, backend services should not be doing that, as they should be left alone with delivering the business logic. This is where an API gateway, a single entry point for all requests, comes in. Let us see what an API gateway is and what features and benefits it offers.
