Gatling vs JMeter - What to Use for Performance Testing

A performance tool with a graphical interface will probably be easier to use at the beginning, but the idea of a performance test as code is the future. Tests are readable and much easier to maintain. Many people are skeptical about Gatling because it requires learning a new programming language - Scala. However, Java is supported with the release of Gatling 3.7.

The Parity Problem: Ensuring Mobile Apps are Secure across Platforms

The problem of security parity is a big one, but it’s part of a larger problem: a general lack of security in mobile apps. By embracing automation for security implementation to the same or greater degree than it has been adopted for feature development, developers can ensure that every app they release for every platform will be protected from hackers, fraudsters, and cybercriminals.

API Friction Complicates Hunting for Cloud Vulnerabilities. SQL Makes it Simple

APIs can tell you everything about your cloud infrastructure, but they're hard to use and work in different ways. What if you could write simple SQL queries that call APIs for you and put results into a database? Steampipe, an open-source project that maps APIs to Postgres foreign tables, makes that dream come true. It's hard enough to reason over data. Acquiring it should be easy, and now it is.

Kafka Streams and Quarkus: Real-Time Processing Events

Consuming Kafka messages is simple; you get them as long as they are produced, but nothing more. But if you need real-time processing of the data (filtering, joining, or manipulating events), just using the Kafka-consuming API might not be the best approach as the resulting code becomes complex. Kafka Streams and Quarkus are the perfect matches to start processing Kafka events in real-time.

It’s Time to Start Growing No-Code Developers

It’s time to start training and promoting people to be “business application no-code developers.” Why? Because everyone who manages a system is now a “developer,” whether they were trained that way or not. And if you don’t do this, your company will run into insurmountable problems when scaling its systems. Read this advice from a CTO on how your org can catch up.

Using GraphQL and Ballerina with Multiple Data Sources

The Ballerina programming language is well-suited to developing GraphQL applications, due to the network abstractions, network-aware type system, clear data representations, and visual diagrams. This article discusses the benefits of GraphQL and Ballerina, and walks through a sample application that retrieves data from a database and a 3rd-party API.

The Compounding (Business) Value of Composable Ecosystems

Being “free” and open source doesn’t hinder the value of these projects to businesses and end users; rather it unlocks it. The composability of open source ecosystems allows the innovation and value of the whole ecosystem to compound on itself.
