KUBERNETES

After an initial phase of builting the blueprint of the customers' business platform, followed by the decision to adopt SUSE Rancher as the Kubernetes platform, Kiratech executed the delivery of the project in the following three epics:

• High availability, in order to deal with the falsification of the individual worker nodes and in consideration of the independance of the physical infrastructure (on-premise/hosting service/public Cloud);
• Inter-component Security, realised through mTLS communication made possible from the implementation of the Istio mesh service;
• Cloud native storage, through the use of Longhorn on Rancher.

The project was characterised by the following technology stack:

This project involved the refactoring of containerised monolithic applications running on Docker Swarm. For each of these applications, the architechture was reformulated according to the Microservices paradigm, using the "strangle the monolith" approach. 

The applications resulting from the Microservice architecture were deployed on Red Hat OpenShift. This project thus involved both an architectural change (refractoring) and a technological change.

The technological aspects are related to the two container orchestration platforms and the accompanying DevOps tools:

The dual transformation of the architecture and platform affected all the artefacts used for the build and deployment. The pipelines on CloudBees were also changed accordingly.
