How to Access AWS From Azure VM Using OpenID Connect

In the day to day operations of a software application, it is common to be in a position to manage and handle multiple cloud providers at the same time.

This can be due to the business requirements or because of technological constraints on the primary cloud provider of the company.

In this blog post we will see how to grant an Azure Virtual Machine access to AWS services, without storing any long-lived credentials and with the power of OpenID Connect.

If you've worked with either cloud, or want inspiration on how to apply this technique to your setup, then this blog post is for you.

Ory Kratos: Headless Authentication, Identity and User Management

Authentication flows are quite common in the modern day software development. What we want from one authentication has a lot of overlapping funcionality with what our other applications need. Even across different industries, you can still see the same patterns apply when it comes to Identity and User Management.

Ory Kratos solves all that user management under one umbrella of identity server, providing a clean headless API that you can ship your own UI with. It empowers you to customize the frontend, while preserving the ever-common backend that is backed by the robust SQL database.

In this blog post, we will cover the introduction and basics of Ory Kratos, as well as the steps and guides to write your integration client.

If you've always wanted to stop reinventing the wheel, reduce code duplication and to follow security best practices, then Ory Kratos and this blog post is for you!

cert-manager: All-in-One Kubernetes TLS Certificate Manager

Kubernetes is a great orchestration tool for managing your applications and all its dependencies. However, it comes with an extensible architecture and with an unopinionated approach to many of the day-to-day operational tasks.

One of these tasks is the management of TLS certificates. This includes issuing as well as renewing certificates from a trusted Certificate Authority. This CA may be a public internet-facing application or an internal service that needs encrypted communication between parties.

In this post, we will introduce the industry de-facto tool of choice for managing certificates in Kubernetes: cert-manager. We will walk you through the installation of the operator, configuring the issuer(s), and receiving a TLS certificate as a Kubernetes Secret for the Ingress or Gateway of your application.

Finally, we will create the Gateway CRD and expose an application securely over HTTPS to the internet.

If that gets you excited, hop on and let's get started!
