ACM AppSet and App build upon ArgoCD's capabilities, integrating closely to offer a powerful multi-cluster application management solution. However, ACM (Advanced Cluster Management) brings some distinct features to the table.
ACM (Advanced Cluster Management) AppSet/App
Integration with ACM:
Centralized Management: ACM provides a centralized hub to manage applications, clusters, policies, and governance.
Placement Rules: With ACM, we can define placement rules to determine which clusters our applications should be deployed to. This feature isn't inherently part of ArgoCD but is possible through ACM's integration.
Governance and Risk: ACM includes governance, risk, and compliance (GRC) policies to ensure our applications meet organizational standards and compliance requirements across all clusters.
Multi-Cluster Management:
Cluster Lifecycle Management: ACM manages the entire lifecycle of clusters, including provisioning, scaling, upgrading, and deprovisioning. ArgoCD, on the other hand, primarily focuses on continuous delivery and application management.
Cluster Observability: ACM offers observability for clusters and applications, giving us insights into the health and performance of our managed clusters.
GitOps Integration:
Extended GitOps: ACM extends ArgoCD's GitOps capabilities by integrating with other tools and offering a broader scope for application delivery and cluster management.
Centralized GitOps: ACM uses ArgoCD's GitOps model to manage applications declaratively, letting us sync our desired state from Git repositories across multiple clusters.
Enhanced Policy Management:
Policies and Compliance: ACM includes policy frameworks that let us enforce security, compliance, and operational policies across all managed clusters and applications.
ArgoCD AppSet/App
Focused Application Delivery:
Application Management: ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It focuses on managing applications, making sure the state defined in Git is reflected in our Kubernetes clusters.
AppSet: ArgoCD ApplicationSets allow us to manage a large number of applications from a single configuration source. This simplifies multi-environment deployments and other repetitive application patterns.
Declarative Configurations:
GitOps: ArgoCD operates on the GitOps principle, where the desired state of applications is defined in Git repositories. ArgoCD continuously ensures this state is achieved in our clusters.
Standalone Use:
Single or Few Clusters: ArgoCD is usually used for managing applications within one or a few clusters. It doesn’t include the broader cluster lifecycle management and governance features that ACM offers.
Scalability for Applications:
AppSet Scalability: ApplicationSets in ArgoCD provide templating and automated deployment of multiple applications. This is especially useful for managing complex applications across multiple environments.
Summary
ACM AppSet and App
We extend ArgoCD’s capabilities to provide centralized, multi-cluster application management, integrated with ACM’s cluster lifecycle management, governance, and policy enforcement features. This includes placement rules, centralized observability, and a broader scope of GitOps capabilities.
ArgoCD AppSet and App
ArgoCD focuses on continuous delivery and application management within Kubernetes clusters using the GitOps model. It offers a robust solution for managing applications declaratively but doesn’t include the broader cluster and governance management features that ACM provides.
In essence, ACM AppSet/App acts as a wrapper around ArgoCD’s capabilities, enhancing and extending them to offer a comprehensive solution for multi-cluster application and cluster management.
