# Progressive-Delivery
Experimenting with Progressive delivery approach in Kubernetes by using Argo Rollouts controller
### Defining Progressive delivery
- Progressive delivery is a term that includes deployment strategies that try to avoid the pitfalls of all-or-nohting deployment strategies
- New versions being deployed don't replace existing versions but **`run in parallel`** for an amount of time receiving live production traffic and are evaluated in terms of correctness and performance before the rollout is considered successful (Before being fully `promoted`)
- The advantages of prgoressive delivery are
- Avoiding downtime
- Shorter time from idea to production
- Limiting the blast radius
---
### Argo Rollouts
- A Kubernetes controller and set of CRDs which provide advanced deployment capabilities
- A `Rollout` is used instead of a deployment
- Both the Rollout and deployment defintions are almost identical with the excpetion of the added `strategy` section that indicates the type of strategy that we want to use
- There are many strategies supported by Argo Rollouts such as Blue Green and Canary ones
