What’s Wrong with the Current OWASP Microservice Security Cheat Sheet?

Modern microservice architectures require evolving security practices. Yet popular resources like the OWASP Microservice Security Cheat Sheet are starting to show their age and need a fresh look.

Updating OWASP’s Microservice Security Cheat Sheet: Authorization Patterns

Authorization patterns explain how distributed systems organize their access control — where and how decisions happen, where policies live — and influence, in turn, how identities and related attributes travel between components.

gRPC

One of the main tasks that business sets for IT as an industry is the creation of effective software, according to criteria that clearly meet the needs of this business. On the other side, one of the main prerequisites for achieving the goals that a business sets for itself is the ability to hire specialists who can create a product in the shortest possible time and/or effectively maintain it. Accordingly, to achieve this, the technology stack used, i.e. tools, must be mature enough, and widely used in the market.

Modules – Microservices – Monoliths

Microservices were supposed to solve every architectural problem conceivable. Not too surprisingly, that was not the case. Now themonoliths thatwe have been developing for decades are supposed to be the solutionagain. Inthis discussion, the foundation for developing complex software systems has been forgotten: Modularization, which is far more important than the question of monoliths vs. microservices.

Happy without a Service Mesh

It does not always have to be a service mesh. Even microservices are not a good idea per se. For good decisions we have to get a deep understanding of the problem first.

code-your-model

Some time ago I was looking for some simple, lightweight tool to document a complex, modularized model. I was not able to find anything that fits my requirements or expectations, so I came up with my own idea. Today, a good 15 months later, I want to introduce it to you.

Microservices? Or Rather Monoliths?

Microservices are a hype. Now, critics suggest to return to monoliths. But does that really help?

The perils of shared code

In this blog article, I want to examine why using a sharing code between microservices may sound attractive in the first place and why it can cause bigger problems than the ones you try to solve.

Why RESTful communication between microservices can be perfectly fine

Recent debates about REST versus message passing in microservice communication have led to some confusion. What is meant with asynchronous communication in this context and why is REST a perfectly valid choice?

Hystrix – to make your fuse blow just in time

Circuit breakers were originally introduced to prevent the escalation of an outage. If your fuse blows occasionally, that does not have to be a bad thing - at least if it is a circuit breaker in the sense of Hystrix. In this article we will introduce you to Hystrix, a library which will help you to increase the stability of your distrubted applications and which will help to prevent cascading error scenarios.
