Micro-services Architecture with Oauth2 and JWT – Part 6 Oauth2 and Web

Comments 0 Comment

The last number of years I have been working in the area of migrating from legacy monolith (web) applications to a (micro) service oriented architecture (in my role of Java / DevOps / Infrastructure engineer). As this is too big of a subject to put in a single blog post, I will split this in 6 parts; (1) Overview, (2) Gateway, (3) Identity Provider, (4) Oauth2/Scopes, (5) Migrating from Legacy, (6) Oauth2 and Web. Oauth2 and Web: To-Do or not…

WebLogic Major Upgrade Without Downtime

WebLogic Major Upgrade Without Downtime

Comments 0 Comment

A trip down memory lane… A long time ago, in 2015, we were running an Oracle WebLogic 11G cluster, which needed to be upgraded to 12C. However, Oracle did only support rolling upgrades for minor versions, not for major versions… In the image above, you see a simplified layout of our cluster (there were more servers and instances in the real setup). Traffic comes in from the left, via a load-balancer (and some apache’s). It was spread across the managed…

My daughter is quite artistic (as any proud parent would say), and created a wire animal in a bottle. For this bottle she wanted some lights at the bottom (inside), but… the requirement was that no wire may go through the glass (which would have made everything lots easier of course). By total coincidence, some weeks earlier I did order some wireless power transfer kits. They contain two coils and two little electronics regulator boards to send and receive wireless…

Summary We are using (self hosted) Jira (the Atlassian Issue Tracker / Scrum / Kanban Board) at the office. And we wanted to receive a chat notification for each newly created ticket, to be received in Microsoft Teams Channels. Teams is a collaboration messenger tool like Slack or RocketChat. Jira can send new ticket/story creations using a web-hook to external tools. The web-hook sends a Jira specific JSON payload, no configuration options possible. The project you are looking at, consists…
