• Virtual Argo CD instances provide one-click installation, zero configuration, and flexibility in managing multiple instances and Kubernetes versions.
• Codefresh uses a centralized setup that is cost-effective, allows for security isolation, and enables testing of new versions without affecting other customers.
• Monitoring is done using Prometheus and Grafana stacks, as well as a proprietary exporter.
• A demo is provided to show how virtual Argo CD instances are provisioned and deprovisioned.

• Argo CD Core is a tool for cluster bootstrapping
• It allows administrators to manage system add-ons of clusters without the burden of SSO
• It is recommended for cluster administrators who already have full access to all the clusters

• Argo CD is a tool for managing Kubernetes applications that can support large numbers of developers and objects
• The presenter offers a conservative benchmark for Argo CD scalability, suggesting that 15,000 objects and 50 clusters are safe limits
• However, the presenter notes that with tweaking, Argo CD can support much larger numbers of objects and clusters
• The presenter emphasizes the importance of security in using Argo CD, particularly in multi-tenant environments
• The presenter suggests using an app of apps pattern to manage large numbers of objects and dependencies
• The presenter recommends splitting Argo CD instances to provide better isolation and prevent noise
• The presenter suggests that a control plane may be necessary for managing large numbers of Argo CD instances
• The presenter notes that Adobe has been speaking at the conference and is part of a larger Adobe Cinematic Universe of talks

• Adobe's internal developer platform standardizes best practices and consolidates engineering efforts across various internal developer teams while providing a flexible CI/CD experience
• GitOps is an architectural paradigm that deploys defined state to a live state on a running system
• Argo CD is an example of GitOps tooling that supports tracking of Kubernetes manifests in Git and supports their deployment and synchronization to a namespace on a cluster
• Argo Workflows is a workflow engine that can run CI/CD pipelines on a Kubernetes cluster
• Multi-tenancy is achieved through the isolation of each component of developer CI/CD workflows and the restriction of application deployment with Argo CD AppProjects and RBAC

• TikTok operates a large network of Kubernetes edge clusters around the world, hosting apps such as Tiktok, live and gaming, using cache and traffic acceleration services offered at our edge clusters.
• The challenge arises when it comes to the deployment management of those edge services on hundreds of edge clusters.
• Argo CD is used to manage cluster applications on the edge.
• The deployment of all edge services follows the same pattern, with a large portion of common configurations and a small portion of cluster-specific configurations.
• The performance and scalability of using Argo CD to manage over 3000 applications across 100 global edge clusters is a challenge.
• The Argo community plans to address these challenges in the future.

• GitOps and Argo CD are used to manage application deployment templates and synchronize with GitHub repositories for deployment.
• Crossplane provides an abstraction platform for infrastructure provisioning, allowing for the management of both cloud-native and non-cloud-native systems.
• An Ansible provider is being developed to bridge the gap between cloud-native and non-cloud-native systems.
• The use of GitOps and crossplane allows for versioning and auditing of infrastructure and ensures that clusters map back to the defined state in GitHub.
• The infrastructure interface is a custom interface, which makes it difficult to adopt GitOps, but crossplane provides a solution to this problem.

• Argo CD bridges the gap between Git and target clusters for deployment
• The core functionality includes creating and syncing applications, visualizing objects, and rolling back changes
• The web terminal feature allows for easy troubleshooting and running commands within pods
• The upcoming 2.5 release includes new features such as project-level RBAC and a new UI for managing applications
• The presenter emphasizes the importance of moving towards full automation and using a two-repo structure for application and GitOps code

• Argo CD and GitOps workflow are used to manage Kubernetes clusters with Git repositories as the source of truth.
• Managing deployments of large numbers of applications/clusters with Argo CD requires complex custom scripting.
• Argo CD ApplicationSet controller works alongside Argo CD to automatically generate Application deployments using templates and parameterization.
• Application Sets can manage multiple Kubernetes clusters and deploy large numbers of applications from multiple repositories using templates and parameterization.
• Application Sets are based on Argo CD applications and can be customized using data from external data sources.
