The presentation discusses the evolution from monolithic applications to microservices, highlighting their benefits such as shorter development cycles and better scalability. Containers, particularly Kubernetes, are introduced as a solution to the challenges posed by microservices, including deployment and orchestration. The speaker emphasizes that modern architecture requires modern tools to support effective service management.

Editor's Notes
- #8: Containers are ally to microservoces
- #11: Throw it behind load balancer
- #16: Service oriented architecture Symphony example Electric guitar and aquistic guitar Resileance is designed for failure
- #17: MASLOW NEXT
- #22: Modern architecture required moders tools
- #23: MASLOW NEXT
- #25: Each VM has complete copy of guest os which uses space and when you code runs it is translated to host os via hypervisor which is an expensive opration. Each container runs only on kernel of the host operating system beside sharng os you can also share libraries and application code with container and there is no translations cost which makes containers efficient then VMs
- #28: MASLOW NEXT
- #29: Bourg -> omega -> k8
- #32: Master, worker nodes and pods
- #33: Declarative model & Desired state
- #34: Pods definition in a a manifest is givent to master which desides on its own how it will be places with various worker nodes. Example pods defincation uses container it describes how many replicas should be there and master then manges it with various worker nodes. If a worker node goes down it means out pod/contianer is down k8 master spuns new pod with another worked node and keep the system in desired state.
