Ephemeral Elastic Infrastructures Flashcards
What is GitOps?
GitOps is a cloud native approach to continuous deployment that leverages theGit version control/source control system as a single source of truth for configuration, infrastructure, and operational procedures.
Software agents alert on any divergence between Git with what’s running in a cluster, and if there’s a difference, Kubernetes reconcilers automatically update or rollback the cluster depending on the case.
What is Ephemeral Elastic Infrastructure?
How computing machines, storage and network resources for builds, testing and production environments are provisioned, configured, instantiated and managed in real time to satisfy the continuous varying workload requirements of continuous delivery pipelines.
What is Cloud-native?
Cloud-native architecture and technologies are an approach to designing, constructing, and operating workloads that are built in the cloud and take full advantage of the cloud computing model.
What is Immutable Infrastructures?
An immutable infrastructure is another infrastructure paradigm in which servers are never modified after they’re deployed. If something needs to be updated, fixed, or modified in any way, new servers built from a common image with the appropriate changes are provisioned to replace the old ones. After they’re validated, they’re put into use and the old ones are decommissioned.
