The reason why I decided to write about the topic of change data capture (CDC) is somehow tightly coupled with the story of event-driven architecture. In my experience, this question pops up frequently. How to pull data from non-event systems and how to transform non-event systems (data) to event-based systems is something that every organization that starts this transformation to an event-centric organization asks itself at the very beginning.

This happens when you have a big (possibly old) core monolithic system that doesn’t have event streaming capabilities, which is slow and expensive to change. Being slow and expensive means that…

There is a lot of buzz going on for some time about events, event driven architecture, event streaming and other variants of those. Even though events and EDA are present for long time this topic gains momentum specially when discussed along side of digitalization and digital transformation topics. As it is with many other things, our understanding of what events are and how should we build our event driven architecture differs from person to person.

Serverless is still a buzzword but what does it mean in terms of applying serverless patterns in enterprise architecture. This article is inspired with AWS training I took and patterns presented in one of the modules of the lecture.

For large enterprises, that have number of legacy systems, serverless is still vague goal. Not only is it difficult to apply those patterns technically but concept usually escapes legacy IT personnel. Legacy systems, monolith applications, are usually very difficult to migrate to microservice architecture or decoupled services. Serverless is even more difficult to implement.

What does serverless means in those enterprises…

Plan is simple — transfer current web site to Google Cloud to high availability environment.

Current implementation is on a VPS hosting — one-in-all server running Apache, PHP, MySQL, Redis — usual suspect for light WP sites.

Application/site is a custom WP Multisite installation with central portal site that servers as a central point for WPMU users. Users can create sites, blogs, add/edit content, web shops… etc. There is plenty of themes and plugins blog users can enable on their site. As well there is custom plugin and a mobile app that integrate all of those things together.
