Transitioning from Prometheus to OpenTelemetry - A Journey of a Cluster's Metrics Evolution

Part 2: Scraping The First Metrics

Having explained the technical implementation of the monitoring stack in our latest blog post, this article focuses on replacing Prometheus with OpenTelemetry Collector to decouple scraping from the storage and query mechanisms. The OpenTelemetry Collector uses various building blocks to construct the telemetry pipeline and requires enabling of the target allocator. Guiding you through this process we provide various practical tips, including processor ordering and horizontal autoscaling."

Immersive Technologies

Part 1: Introduction to immersive technologies

Immersive technologies, alternatively referred to as XR technologies, possess the capability to either augment or replace the physical world with a digitally simulated one. This article provides an overview by describing the three categories of immersive technologies, including relevant background information, and significant use cases.

Data mesh as an element of data strategy

In this article we discuss the challenges of storing vast amounts of data to become a value-driven organization and introduce data mesh, an innovative technology that addresses these challenges. We outline the four principles of data mesh and provide a step-by-step framework for implementing the architecture. The article also gives an example of data mesh implementation using serverless tools on AWS and emphasizes that the selection between data mesh and traditional data architectures depends on the specific needs, capabilities, and goals of the business.

Kong - The Gateway without Limitations

Part 5: mTLS Header

Mutual transport layer security (mTLS) with consumer authentication using client certificates at the Kong Gateway plays an important role in building a zero-trust architecture. But perimeter security devices that perform TLS termination, so-called TLS terminating reverse proxies (TTRP), break the automatic mapping of client certificates to Kong consumers. This blog demonstrates mTLS consumer authentication even with preceding TTRPs, without requiring TCP passthrough.

Kong - The Gateway without Limitations

Part 4: SAML 2.0 Bearer Assertion Flow for OAuth 2.0

My last blog provided a solution for implementing an OAuth 2.0-based On-Behalf-Of (delegation) grant flow. This time it’s about implementing a Security Assertion Markup Language (SAML) 2.0 Profile for OAuth 2.0 Client Authentication and Authorization Grants. This flow allows OAuth 2.0 clients to obtain access tokens by presenting SAML 2.0 assertions as a form of authentication. This somewhat extended grant flow expands the scope for exchanging authentication and authorization data between different parties with seamless management, all achieved through the API Gateway.
