Global hybrid multi cloud applications (GHMAs) auto scale vertically and horizontally in response to spikes in request traffic and processing load.
Auto scaling mechanisms for GHMAs are available on prem, in the public cloud, or in any combination globally. [Note: This whitepaper defines GHMAs.]
This works because GHMAs abstract the underlying deployment infrastructure and the event-driven architecture (EDA) messaging system, regardless of where they are running.
This blog post uses a simplified international payment processing flow to illustrate how horizontal and vertical auto scaling works for GHMAs.
Auto scaling mechanisms respond to an unexpected spike in request traffic or processing by increasing resources and replicating microservices.
Auto scaling mechanisms also replicate microservices horizontally and/or vertically when needed to handle increased processing volumes, as follows:
- Horizontal auto scaling: Automatic replication of a microservice on multiple Kubernetes clusters across multiple VMs
- Vertical auto scaling: Automatic replication of a microservice within the same Kuberbetes cluster on the same VM
