Managing Edge Scale with Policy-Based Workload Placement
In the previous chapter, you learned about and practiced developing Open Horizon services, which form the building blocks of deploying underlying microservices on Edge nodes. You also developed and practiced the pattern-based approach to deploying a collection of services on Edge nodes. The pattern-based approach is simple and might be a reasonable solution for deploying services on a small number of Edge nodes with few microservices. However, we have also seen the limitations of the pattern-based approach when applications need flexibility in deploying microservices on many Edge nodes.
This is where policy-based deployment comes into play. In this chapter, we will develop and practice such an approach by leveraging all the knowledge that we have acquired so far.
In this chapter, we will cover the following main topics:
- Policy-based application workload placement
- Developing a service policy
- Developing a...
