A competitor recently published a microbenchmark comparing the performance of their stack to Quarkus. The Quarkus team feels this microbenchmark shouldn’t be taken at face value because it wasn’t making a like-to-like comparison leading to incorrect conclusions. Both of the two frameworks under comparison support reactive processing. Reactive processing enables running the business logic directly on the IO thread, which ultimately performs better in microbenchmark focusing on response time and concurrency. The microbenchmark should have been written so that both frameworks (or neither framework) obtain this benefit. Anyway, this turns out to be a very interesting topic and good information for Quarkus users, so read on.

What is DevOps? This question has no clear answer, because the truth lies somewhere between corporate culture, tooling, methodology and different approaches to working. Nevertheless, there are of course factors that give an indication of the extent to which DevOps has arrived in a company or a team. With our large DevOps survey we want to find out how your company is doing with the implementation of DevOps.

The birth of domain-driven design dates back to 2003. Eric Evans’ book “Domain-Driven Design: Tackling Complexity in the Heart of Software” was a milestone and is still widely read today. The book “Implementing Domain-Driven Design” by Vaughn Vernon has also contributed significantly to the spread of DDD. We talked to Vaughn about the motivation and core ideas behind DDD and its relationship to microservices and reactive architectures.

Watch CEO of Clasnostic, Tobias Kunze discuss how to manage your microservice ecosystem for business agility in this session from DevOpsCon. He focuses on the challenges that he faced and demonstrates how to manage a service landscape and take control of the ecosystem.

In this blog, we are going to review how cloud native application development can be simplified by moving from traditional RDBMS scaling techniques (such as vertical scaling using load balancers) to more modern distributed SQL databases such as YugabyteDB which allow horizontal scaling with cluster-aware JDBC drivers.

Every Monday, we take a step back and look at all the cool stuff that went down during the previous week. Last week, the major version GraalVM 20.0 was released with lots of new language features. We also showed this year’s trends for software engineers, how to navigate OpenJDK support, and how to test Java microservices applications.

Eclipse MicroProfile 3.3 has arrived. This incremental release focuses on aspects such as a richer integration between MicroProfile APIs and continued alignment with CDI, JAX-RS, JSON-P, and JSON-B. It updates five different areas, including Metrics, Fault Tolerance, and Health.

Although it is essential, testing Java apps has become more complicated than ever with the increase of DevOps and new development challenges. Thus, testing strategies need to adapt in order to fit the new realities of microservices. Rod Cope, CTO of Perforce Software, examines how to test Java microservices applications and how to overcome some of the hurdles.

Every Monday, we take a step back and look at all the cool stuff that went down during the previous week. Last week, Angular 9 continued to spark your interest as we took a closer look at Ivy, the new compiler it has on board. Other topics include the latest version of Groovy, the International Day of Women & Girls in Science, and how to build better microservices.

Before Helidon version 2.0 arrives later this year, you can catch a preview of some of its upcoming features with the Helidon 2.0.0-M1 release. Helidon is a collection of Java libraries that made building microservices easier and 2.0 has some big changes in store, including GraalVM support, a new database client, a command line tool, web client, and extended Jakarta EE specifications support.

Kong is an API platform for multi-cloud and hybrid organizations, available as both FOSS and as an enterprise platform. Dennis Kelly, former senior DevOps engineer at Zillow Group, implemented Kong in the Trulia DevOps group. In this article, he recounts how they vetted Kong, what solutions it offered, and how it fundamentally changed their strategy.

Symfony 4 and the introduction of Flex put a focus on enabling developers to create microservice-style applications with Symfony. In a microservice architecture, delegating tasks to other services or distributing data between these services is a challenge most monolith applications do not have to deal with. Find out more in Denis Brumann’s informative session.

Graduating from its beta version, Eclipse MicroProfile Starter has reached its version 1.0 release and is now generally available. In addition to its easy-to-use GUI with simple drop-down menus, v1.0 adds a REST API for generating projects using the command line and through IDE extensions. See what’s new in this tool that helps you create cloud-native Java microservices with just a few clicks.

As deep systems become more prevalent in today’s high-speed digital enterprises, DevOps must find the best tools in order to manage them. We spoke with Ben Sigelman, co-founder and CEO at LightStep, about how deep systems emerge, microservice observability, and the difficult aspects of dealing with deep systems.
