What is EaaS and does it even make sense? In this article we discuss some concepts found in EaaS offerings and explore where and under which circumstances they make sense. This article is split in two parts, the first one discusses some concepts of EaaS, whether they may make sense…

Spring Cloud Vault Config allows your Spring application to retrieve configuration data from Hashicorp Vault. In addition, you can let Vault manage your Database Accounts for your application. This is achieved with a secret backend called ‘database’, that allows Vault to create database accounts on the fly for each instance…

At Digital Frontiers we all have our favourite languages. The other day we were arguing about advantages and shortcomings of some specific ones and decided to have a closer look at them, using a Sudoku verifier as common example. …

Microservices don’t always have to speak HTTP. Another common approach is using asynchronous communication via events. A well known middleware, Apache Kafka, despite the fact being at home in the Java eco-system, provides adapters for many platforms. How well can a Rust application be integrated into a mostly foreign environment…

Should you write your next microservices in Rust? In this post you will learn how you can develop such an application with Rust and you will be able to answer the question, if you should. This is the first part of a series of articles on how you can create…

A hands-on walk-trough on how to create a REST-API with Rust, Rocket and Diesel — What and why If you are comfortable writing web-services in Java, why should you try writing a web-service in Rust? Microservices enable us to quickly scale our application according to consumer needs, requiring reasonable start-up times to achieve elasticity. When considering a serverless scenario, this aspect is even more important. But is it…

Rust is a systems programming language, that describes itself as a ‘safe, concurrent, practical language’. Because Rust supports cross compilation since its early stages and provides a platform agnostic standard library, it seems to be a perfect fit to develop native, high-performant graphical desktop applications. I therefore set out to…

Rust praises itself as being capable of creating some of the fastest executables, while at the same time supporting high-level abstractions. In most cases, the abstractions are resolved at compile-time, leading to ‘zero-cost abstractions’ without any runtime-overhead. In most cases function calls are implemented using fast static dispatching. But what…
