    This is literally gold, Now I understand how to learn something
    1) knowing what are the problems a tech tool can solve
    2) understanding why we use X tool
    3) Apply your learnings
    This is what I take from this video, thanks a ton

    the traffic lane analogy for explaining the metrics of requests sent by service A and received by service B was awesome.. only that in the visual, A was receiving because traffic was incoming and B was sending cos traffic was going away :D

    How do you maintain referential integrity between the videos and playlist databases? Can you do a video on microservice architecture and SQL databases to explain how monolithic apps can be broken into microservices when they all use the same SQL database?

    • @MarcelDempers
      @MarcelDempers  4 года назад +3

      Ideally in world of distributed systems, services should not leak their data model and instead provide a contract thats backward compatible. In this case, playlists-api should not know how videos are stored by the videos-api. Only way to access the data is through the videos-api. The videos-api is able to change its backing service from MySQL to Redis without impacting dependent services as the contract on videos-api (accepting an ID on a GET request) remains consistent. So the videos domain is controlled by its endpoint and no other services should be able to access its database directly. I would recommend to try avoid sharing databases between services as its an anti pattern.
      12 Factor is a great read on this 12factor.net/backing-services
      Microservice video series sounds like a good plan 💪🏽

  • @nyanRETARD
    @nyanRETARD 4 года назад

    Just awesome! But I have one question. If you have your Kubernete cluster on DigitalOcean inside one VPC network, which means that communication between pods is already secure. So what would be the use case for service mesh with TLS connection between pods?

    • @MarcelDempers
      @MarcelDempers  4 года назад

      Thank you 💪🏽 TLS between pods means the traffic is encrypted end to end. If your network is comprised, it would be increasingly difficult to sniff packets on the network.

    • @fjgreger
      @fjgreger 4 года назад

      Many kubernetes cluster contain different Environment (prod, stage, Dev), different projects or multiple tenants, so it better to secure the communication.

    i am looking to learn a service mesh what would you suggest i should learn between AWS App mesh and istio?

    • @MarcelDempers
      @MarcelDempers  3 года назад

      Personally I would start with Linkerd, then Istio, then also checkout Open Service Mesh.
      Linkerd is the most beginner friendly mesh out there and you can play around with all its functionality locally using a local kind cluster. It will help you understand all the functionality of a mesh.
      Istio is slightly more advanced to understand, but once you've played with Linkerd, Istio becomes a real breeze.
      You don't have to go too advance with Istio, just play with the basics.
      And finally, Open Service Mesh, will teach you the SMI concepts which may form the foundation of service mesh implementations on Kubernetes going forward.

  • @Swaad_aur_Safar
    @Swaad_aur_Safar Год назад

    Mate when you do port forward to playlist api to port 81 locally how does my browser understand it .. I mean you refreshed localhost in the url and it got the content.. same when you deployed db then you didn’t port fwd it but still you refreshed it and got the videos .. how this works ? Sorry if it’s a stupid question

    • @MarcelDempers
      @MarcelDempers  Год назад

      In the first part of the video I used docker compose, no port forwarding, so all services start and the content is there, that is why you can see it all. Later in the video we deploy each service, starting with videos web, at that stage, port--forward does not show any content, we deploy the next service and piece by piece you will notice content coming through in the browser.

  • @shashikanthreddy5872
    @shashikanthreddy5872 4 года назад

    Thanks for your awesome videos.... Looking forward for more videos on ServiceMesh. My question is how does videos-web container integrated with videos-api & playlists-api? How does Videos-web know about Videos-api/playlist-api?

    • @MarcelDempers
      @MarcelDempers  4 года назад

      In this simple demo, videos web runs as a web app (html). It has the URL of playlist api and accesses it via GET call. Videos Api is private and Playlists API is accessing videos API using a GET call over private DNS.
      This will evolve and an Ingress gateway will be introduced.

    Hi, so good. Could you please make a video on session replication between pods in kubernetes?

    • @MarcelDempers
      @MarcelDempers  4 года назад +2

      Thanks 💪🏽I would highly recommend not to keep sessions in processes (pods), instead move session out (to something like a database). Processes should allow for concurrency (scale out) and share nothing among them.

    How is this different or how does it relate to a APM product, say NewRelic?

    • @MarcelDempers
      @MarcelDempers  4 года назад +3

      It's very different. NewRelic integrates at code level (SDK) so it gives deep observability into method\function tracing and instrumentation. NewRelic would compare more to Prometheus + Jaeger to a degree. Service mesh gives you more network level tracing focusing on endpoints. I.E When service A calls B, B's endpoint took 5ms to respond, but it does not instrument the code of endpoint B which is what NewRelic would do if that makes sense 💪🏽
