Spring Meetup Paris - Back to the basics of Spring (Boot)Eric SIBER
?
Le document est une pr¨¦sentation d¨¦taill¨¦e du cadre Spring et de son utilisation pour le d¨¦veloppement d'applications Java, couvrant des th¨¨mes comme les versions du framework, la d¨¦claration de beans, l'injection de d¨¦pendances, ainsi que les concepts cl¨¦s tels que l'inversion de contr?le et les design patterns. Il aborde ¨¦galement l'historique de Spring, les outils compatibles, et les diff¨¦rentes approches de configuration y compris XML, annotations, et Java config. Enfin, il ¨¦voque les fonctionnalit¨¦s avanc¨¦es telles que les namespaces et l'externalisation des propri¨¦t¨¦s.
The document discusses the architecture of modular monoliths using Spring, emphasizing the benefits of a single project structure, straightforward infrastructure, and independent service deployment. It outlines a systematic approach to modularization, encapsulation, and context boundaries, supported by various references and resources. Additionally, it highlights that modular designs allow for better organization and specialized problem-solving capabilities.

This presentation start from basic concept such as container and container orchestration
And then go through Kubernetes internal especially Master Node components and Work Node components and show and explain core mechanism with codes.
Talk about Kubernetes cluster on baremetal servers for serve internal services.
Sharing my experiences about setup and manage kubernetes cluster on premise.
At first, start with single master kubernetes cluster and enhanced by many opensource softwares.
Add more master nodes for increase server availability.
Use Rook, MetalLB, Ceph, mysql-operator and more opensource projects.
Helm was used to deploy Prometheus and the Prometheus stack on an EKS cluster for monitoring purposes. This included deploying Prometheus, Grafana, Alertmanager and associated pods and services. Some key steps taken were adding the Prometheus chart repository, configuring storage classes, and accessing the deployed applications. Potential issues with default storage configurations were also discussed.
The document provides instructions for deploying Prometheus and the Kube Prometheus Stack on NKS. Key steps include:
1. Deploying Prometheus using Helm with custom storage class and service type settings.
2. Verifying successful deployment by checking pods, services, and accessing the Prometheus UI.
3. Deploying the Kube Prometheus Stack using Helm, again with custom storage class and service type settings.
4. Verifying successful deployment including checking pods, services, and accessing the Grafana UI with default credentials to view pre-configured dashboards importing from Prometheus data.
The document provides instructions for deploying and managing an EKS (Elastic Kubernetes Service) cluster on AWS using eksctl. It outlines the steps to install eksctl and kubectl, deploy an EKS cluster called "eks-122" using eksctl with default settings, verify the cluster is active with 2 nodes, and finally delete the cluster when it is no longer needed.
The document discusses the significance of Kubernetes for network engineers, emphasizing its growing importance in modern IT environments. It highlights the author's role as a technical advisor and contributor to various IT communities, while also providing educational resources on Kubernetes and Ansible. Additionally, it outlines the evolving demands on traditional network engineers and encourages collaborative learning in the IT field.
The document discusses how to set up a CDN on Google Kubernetes Engine (GKE). It involves:
1. Creating a deployment and exposing it via a LoadBalancer to test performance without CDN. Tests from Japan and Oregon VMs show response times from Japan are higher.
2. Creating an Ingress resource and exposing it, then enabling Cloud CDN on the Ingress backend.
3. Testing performance from the Oregon VM to the Ingress IP, which now benefits from the CDN, shows improved response times compared to testing the LoadBalancer without CDN.
The myths of deprecating docker in kubernetesJo Hoon
?
This document addresses the myths surrounding the deprecation of Docker in Kubernetes, explaining that while Docker's integration is changing, it will not significantly impact most users already using containerd. It notes the transition to container runtimes and assures that customers using various cloud providers will face minimal disruptions. Additionally, it highlights that administrators will still have the option to use Dockershim in the future, with resources provided for further information.
This document discusses using Ansible to configure Dell EMC networking devices running OS10. It includes examples of using Ansible ad-hoc commands to ping devices and retrieve information using the dellos10_command module. It also provides a YAML playbook that creates VLAN 11 on different devices and interfaces and configures BFD between spine switches and the access switch.
