In order to understand the concepts, we will first look at the new challenges introduced by a Microservice Architecture. Then we will see how different features of a Service Mesh solve these challenges. We will look at how Istio implements Service Mesh and learn about Istio architecture as well as how to configure Istio for our microservice application. #servicemesh #istio #kubernetes #techworldwithnana ▬▬▬▬▬▬ T I M E S T A M P S ⏰ ▬▬▬▬▬▬ 0:00 - Intro 0:53 - Challenges of a microservice architecture 5:11 - Solution: Service Mesh with Sidecar Pattern 6:15 - Service Mesh Traffic Split feature 7:25 - Istio Architecture 9:05 - How to configure Istio? 11:57 - Istio Features: Service Discovery, Security, Metrics & Tracing 13:19 - Istio Gateway 14:06 - Final Overview: Traffic Flow with Istio ▬▬▬▬▬▬ Want to learn more? 🚀 ▬▬▬▬▬▬ Full K8s course course ► https://youtu.be/X48VuDVv0do DevOps Tools, like Terraform, Prometheus ► https://bit.ly/2W9UEq6 Full Docker course ► https://youtu.be/3c-iBn73dDE Jenkins Pipeline Tutorials ► https://bit.ly/2Wunx08 ▬▬▬▬▬▬ Connect with me 👋 ▬▬▬▬▬▬ Join private Facebook group ► https://bit.ly/32UVSZP Don't forget to subscribe ► https://bit.ly/3mO4jxT DEV ► https://bit.ly/3h2fqiO INSTAGRAM ► https://bit.ly/2F3LXYJ TWITTER ► https://bit.ly/3i54PUB LINKEDIN ► https://bit.ly/3hWOLVT ▬▬▬▬▬▬ Courses & Bootcamp & Ebooks 🚀 ▬▬▬▬▬▬ ► Become a DevOps Engineer - full educational program 👉🏼 https://bit.ly/45mXaer ► High-Quality and Hands-On Courses 👉🏼 https://bit.ly/3BNS8Kv ► Kubernetes 101 - compact and easy-to-read ebook bundle 👉🏼 https://bit.ly/3Ozl28x
