A quick tour around Azure Dev Spaces

1. A quick tour around
Azure Dev Spaces

2. Monolith vs
microservice(s)

3. Monolith
The Good
● Fewer moving parts enables easy
deployment

4. Monolith
The “Good”
● Fewer moving parts enables easy
deployment
The “Bad”
● Longer Release cycles
● Update to one functionality requires
redeployment of the entire codebase

5. The biggest questions ever asked (some of)
● Is the universe deterministic?

6. The biggest questions ever asked (some of)
● Is the universe deterministic?
● What happens after you die?

7. The biggest questions ever asked (some of)
● Is the universe deterministic?
● What happens after you die?
● What is a microservice?

9. Microservice architecture
The “Good”
● An application is sum of its
components
● Better fault isolation
● Components can be spread across
multiple servers
The “Bad”
● Many components, many moving
parts
● Difficult to manage inter-
communication
● Manual management can be
difficult

Kubernetes

12. Kubernetes

14. K8s
Greek for “Helmsman” < the person who steers a ship

15. ● Born in Google
● Donated to CNCF in 2014
● Open source (Apache 2.0)
● v1.0 July 2015
● Written in Go/Golang
● Code is on GitHub (where otherwise?)
K8s: some infos

16. K8s: the big picture view

17. K8s: big picture view
● The Master is responsible for
managing the cluster

18. K8s: big picture view
● The Master is responsible for
managing the cluster
● A node is a VM or a physical
computer that serves as a worker
machine in a Kubernetes cluster.

19. K8s + Azure = AKS

20. Self-hosting K8s cluster
Manually install master
and worker nodes
Need to consider master HA,
adding additional worker
nodes, patching, updates, ...

21. Azure Kubernetes Service
● Simplifies deployment, management and
operations of K8s
● Makes it quick and easy to deploy and manage
containerized applications without container
orchestration expertise
● Eliminates the burden of ongoing operations and
maintenance by provisioning, upgrading and
scaling resources on demand

23. K8s is great for deploying, running and
managing cloud-native applications…

24. K8s is great for deploying, running and
managing cloud-native applications…
...but what about building those applications?

25. Azure Dev Spaces
● Share an AKS cluster for team development
● Onboard new team members with minimal machine setup
● Test code end-to-end without replicating or simulating deps
