What is Argo CD? And When Was Argo CD Established?

What Is Argo CD?

Argo CD is declarative Kubernetes GitOps continuous delivery.

In DevOps, ArgoCD is a Continuous Delivery (CD) technology that has become well-liked for delivering applications to Kubernetes. It is based on the GitOps deployment methodology.

When was Argo CD Established?

Argo CD was created at Intuit and made publicly available following Applatix’s 2018 acquisition by Intuit. The founding developers of Applatix, Hong Wang, Jesse Suen, and Alexander Matyushentsev, made the Argo project open-source in 2017.

Why Argo CD?

Declarative and version-controlled application definitions, configurations, and environments are ideal. Automated, auditable, and easily comprehensible application deployment and lifecycle management are essential.

Getting Started

Quick Start

kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

For some features, more user-friendly documentation is offered. Refer to the upgrade guide if you want to upgrade your Argo CD. Those interested in creating third-party connectors can access developer-oriented resources.

How it works

Argo CD defines the intended application state by employing Git repositories as the source of truth, in accordance with the GitOps pattern. There are various approaches to specify Kubernetes manifests:

Applications for Customization

Helm charts

JSONNET files

Simple YAML/JSON manifest directory

Any custom configuration management tool that is set up as a plugin

The deployment of the intended application states in the designated target settings is automated by Argo CD. Deployments of applications can monitor changes to branches, tags, or pinned to a particular manifest version at a Git commit.

Architecture

The implementation of Argo CD is a Kubernetes controller that continually observes active apps and contrasts their present, live state with the target state (as defined in the Git repository). Out Of Sync is the term used to describe a deployed application whose live state differs from the target state. In addition to reporting and visualizing the differences, Argo CD offers the ability to manually or automatically sync the current state back to the intended goal state. The designated target environments can automatically apply and reflect any changes made to the intended target state in the Git repository.

Components

API Server

The Web UI, CLI, and CI/CD systems use the API, which is exposed by the gRPC/REST server. Its duties include the following:

Status reporting and application management

Launching application functions (such as rollback, sync, and user-defined actions)

Cluster credential management and repository (k8s secrets)

RBAC enforcement

Authentication, and auth delegation to outside identity providers

Git webhook event listener/forwarder

Repository Server

An internal service called the repository server keeps a local cache of the Git repository containing the application manifests. When given the following inputs, it is in charge of creating and returning the Kubernetes manifests:

URL of the repository

Revision (tag, branch, commit)

Path of the application

Template-specific configurations: helm values.yaml, parameters

A Kubernetes controller known as the application controller keeps an eye on all active apps and contrasts their actual, live state with the intended target state as defined in the repository. When it identifies an Out Of Sync application state, it may take remedial action. It is in charge of calling any user-specified hooks for lifecycle events (Sync, PostSync, and PreSync).

Features

Applications are automatically deployed to designated target environments.

Multiple configuration management/templating tools (Kustomize, Helm, Jsonnet, and plain-YAML) are supported.

Capacity to oversee and implement across several clusters

Integration of SSO (OIDC, OAuth2, LDAP, SAML 2.0, Microsoft, LinkedIn, GitHub, GitLab)

RBAC and multi-tenancy authorization policies

Rollback/Roll-anywhere to any Git repository-committed application configuration

Analysis of the application resources’ health state

Automated visualization and detection of configuration drift

Applications can be synced manually or automatically to their desired state.

Web user interface that shows program activity in real time

CLI for CI integration and automation

Integration of webhooks (GitHub, BitBucket, GitLab)

Tokens of access for automation

Hooks for PreSync, Sync, and PostSync to facilitate intricate application rollouts (such as canary and blue/green upgrades)

Application event and API call audit trails

Prometheus measurements

To override helm parameters in Git, use parameter overrides.

Integrating ROSA Applications with AWS Services (CS221)

As cloud-native architectures become the backbone of modern application deployments, combining the power of Red Hat OpenShift Service on AWS (ROSA) with native AWS services unlocks immense value for developers and DevOps teams alike. In this blog post, we explore how to integrate ROSA-hosted applications with AWS services to build scalable, secure, and cloud-optimized solutions — a key skill set emphasized in the CS221 course.

🚀 What is ROSA?

Red Hat OpenShift Service on AWS (ROSA) is a managed OpenShift platform that runs natively on AWS. It allows organizations to deploy Kubernetes-based applications while leveraging the scalability and global reach of AWS, without managing the underlying infrastructure.

With ROSA, you get:

Fully managed OpenShift clusters

Integrated with AWS IAM and billing

Access to AWS services like RDS, S3, DynamoDB, Lambda, etc.

Native CI/CD, container orchestration, and operator support

🧩 Why Integrate ROSA with AWS Services?

ROSA applications often need to interact with services like:

Amazon S3 for object storage

Amazon RDS or DynamoDB for database integration

Amazon SNS/SQS for messaging and queuing

AWS Secrets Manager or SSM Parameter Store for secrets management

Amazon CloudWatch for monitoring and logging

Integration enhances your application’s:

Scalability — Offload data, caching, messaging to AWS-native services

Security — Use IAM roles and policies for fine-grained access control

Resilience — Rely on AWS SLAs for critical components

Observability — Monitor and trace hybrid workloads via CloudWatch and X-Ray

🔐 IAM and Permissions: Secure Integration First

A crucial part of ROSA-AWS integration is managing IAM roles and policies securely.

Steps:

Create IAM Roles for Service Accounts (IRSA):

ROSA supports IAM Roles for Service Accounts, allowing pods to securely access AWS services without hardcoding credentials.

Attach IAM Policy to the Role:

Example: An application that uploads files to S3 will need the following permissions:{ "Effect": "Allow", "Action": ["s3:PutObject", "s3:GetObject"], "Resource": "arn:aws:s3:::my-bucket-name/*" }

Annotate OpenShift Service Account:

Use oc annotate to associate your OpenShift service account with the IAM role.

📦 Common Integration Use Cases

1. Storing App Logs in S3

Use a Fluentd or Loki pipeline to export logs from OpenShift to Amazon S3.

2. Connecting ROSA Apps to RDS

Applications can use standard drivers (PostgreSQL, MySQL) to connect to RDS endpoints — make sure to configure VPC and security groups appropriately.

3. Triggering AWS Lambda from ROSA

Set up an API Gateway or SNS topic to allow OpenShift applications to invoke serverless functions in AWS for batch processing or asynchronous tasks.

4. Using AWS Secrets Manager

Mount secrets securely in pods using CSI drivers or inject them using operators.

🛠 Hands-On Example: Accessing S3 from ROSA Pod

Here’s a quick walkthrough:

Create an IAM Role with S3 permissions.

Associate the role with a Kubernetes service account.

Deploy your pod using that service account.

Use AWS SDK (e.g., boto3 for Python) inside your app to access S3.

oc create sa s3-access oc annotate sa s3-access eks.amazonaws.com/role-arn=arn:aws:iam::<account-id>:role/S3AccessRole

Then reference s3-access in your pod’s YAML.

📚 ROSA CS221 Course Highlights

The CS221 course from Red Hat focuses on:

Configuring service accounts and roles

Setting up secure access to AWS services

Using OpenShift tools and operators to manage external integrations

Best practices for hybrid cloud observability and logging

It’s a great choice for developers, cloud engineers, and architects aiming to harness the full potential of ROSA + AWS.

✅ Final Thoughts

Integrating ROSA with AWS services enables teams to build robust, cloud-native applications using best-in-class tools from both Red Hat and AWS. Whether it's persistent storage, messaging, serverless computing, or monitoring — AWS services complement ROSA perfectly.

Mastering these integrations through real-world use cases or formal training (like CS221) can significantly uplift your DevOps capabilities in hybrid cloud environments.

From Code to Production: Streamlining the ML Lifecycle with Kubernetes and Kubeflow

In today’s AI-driven landscape, organizations are increasingly looking to scale their machine learning (ML) initiatives from isolated experiments to production-grade deployments. However, operationalizing ML is not trivial—it involves a complex set of challenges including infrastructure management, workflow automation, reproducibility, and deployment governance.

To address these, industry leaders are turning to Kubernetes and Kubeflow—tools that bring DevOps best practices to the ML lifecycle, enabling scalable, reliable, and maintainable ML workflows across teams and environments.

The Complexity of Operationalizing Machine Learning

While data scientists often begin with model development in local environments or notebooks, this initial experimentation phase represents only a fraction of the full ML lifecycle. Moving from prototype to production requires:

Coordinating multi-step workflows (e.g., preprocessing, training, validation, deployment)

Managing compute-intensive tasks and scaling across GPUs or distributed environments

Ensuring reproducibility across versions, datasets, and model iterations

Enabling continuous integration and delivery (CI/CD) for ML pipelines

Monitoring model performance and retraining when necessary

Without the right infrastructure, these steps become manual, error-prone, and difficult to maintain at scale.

Kubernetes: The Infrastructure Backbone

Kubernetes has emerged as the de facto standard for container orchestration and infrastructure automation. Its relevance in ML stems from its ability to:

Dynamically allocate compute resources based on workload requirements

Standardize deployment environments across cloud and on-premise infrastructure

Provide high availability, fault tolerance, and scalability for training and serving

Enable microservices-based architecture for modular, maintainable ML pipelines

By containerizing ML workloads and running them on Kubernetes, teams gain consistency, flexibility, and control—essential attributes for production-grade ML.

Kubeflow: Machine Learning at Scale

Kubeflow, built on Kubernetes, is a dedicated platform for managing the entire ML lifecycle. It abstracts the complexities of infrastructure, allowing teams to focus on modeling and experimentation while automating the rest. Key features include:

Kubeflow Pipelines: Define and orchestrate repeatable, modular ML workflows

Why Should your GPU cloud management software be Kubernetes agnostic?

As organizations, including Neoclouds and sovereign entities, develop GPU cloud infrastructures to support AI workloads, many cloud management solutions come bundled with a specific Kubernetes distribution. While this bundling might appear convenient initially, it often leads to significant long-term challenges, primarily due to vendor lock-in.

Such tightly integrated solutions can become inflexible, incompatible with existing enterprise IT environments, and difficult to scale across diverse infrastructures. In contrast, modern GPU cloud management software should be Kubernetes-aware—capable of integrating seamlessly with any CNCF-compliant Kubernetes cluster—rather than being bound to a particular distribution.

Challenges with Bundled Kubernetes Distributions

One of the most pressing issues with bundled Kubernetes solutions is vendor lock-in. When GPU cloud management software is tightly coupled with a specific Kubernetes distribution, it restricts the freedom to adopt or integrate with existing or preferred Kubernetes environments already deployed within the organization. This limits flexibility and often forces organizations into long-term dependencies on a single vendor.

Another concern is operational rigidity. These bundled solutions typically offer limited support for third-party monitoring, alerting, and optimization tools, thereby hampering operational visibility and performance tuning. They also constrain customization options, making it harder to adapt the platform to specific infrastructure or workload needs.

The lack of advanced multi-tenancy features further compounds the problem. While many of these platforms offer basic role-based access control (RBAC) and namespace isolation, they fall short when it comes to supporting complex, enterprise-grade multi-tenant environments that require deeper isolation of resources and policies.

Furthermore, hybrid cloud support is often inadequate in such stacks. Portability between on-premises, hybrid, or edge environments is either limited or non-existent, making it difficult to extend workloads across multiple infrastructures or federate across clouds.

Lastly, there's a frequent misalignment with enterprise DevOps practices. Enterprises often have standardized Kubernetes distributions and established CI/CD pipelines. Introducing a new, tightly-coupled distribution disrupts these processes, requiring lengthy certification cycles and integration efforts to bring the new solution in line with internal systems.

Defining Kubernetes-Aware Management

A Kubernetes-aware GPU cloud management solution should:

Operate across multiple clusters, accommodating various tenants, regions, or environments.

Be deployable atop any Kubernetes distribution without enforcing a specific one.

Integrate with existing Kubernetes-native tools like Prometheus, Grafana, Istio, and cert-manager.

Support GPU-aware scheduling frameworks such as Run:AI, Ray, and SLURM as optional plugins, not mandatory dependencies.

The aarna.ml GPU CMS Advantage

The aarna.ml GPU Cloud Management Software (CMS) exemplifies a platform-agnostic approach, designed for cloud providers and enterprise AI platforms. Its key features include:

Compatibility with any CNCF-compliant Kubernetes cluster, including Upstream Kubernetes, OpenShift, EKS, AKS, and SUSE Rancher/RKE.

Unified management of multiple clusters through a centralized control plane.

Robust multi-tenancy support via per-tenant namespaces, RBAC policies, and storage/network isolation, independent of the underlying Kubernetes distribution.

Integration with GPU scheduling frameworks like Ray, Run:AI, and SLURM, tailored to specific workload requirements.

Orchestration capabilities for bare-metal, virtual machine, and container workloads across both Kubernetes and non-Kubernetes environments.

Emphasis on automation, abstraction, and policy-driven management to avoid distribution lock-in.

This approach ensures maximum flexibility, alignment with enterprise architectures, and the freedom to evolve underlying platforms, catering to Neoclouds, sovereign clouds, and private GPU cloud providers alike.

Comparative Overview

Unlike bundled GPU orchestration platforms that come tied to specific Kubernetes distributions, aarna.ml GPU CMS offers a completely vendor-neutral approach. Most tightly integrated solutions rely on their own Kubernetes versions, making them incompatible with broader IT environments. In contrast, aarna.ml is fully compatible with any CNCF-compliant Kubernetes, giving enterprises the freedom to choose what works best for them.

Additionally, multi-cluster support is often limited or non-existent in coupled stacks, while aarna.ml provides robust multi-cluster capabilities out of the box. In terms of multi-tenancy, traditional stacks may offer only basic role-based access and namespace management. Aarna.ml, however, delivers full tenant isolation and policy controls designed for enterprise-grade environments.

Support for external infrastructure is another differentiator. Coupled stacks generally do not support hybrid or external deployments effectively, whereas aarna.ml is built to span on-prem, cloud, and edge. And when it comes to GPU scheduler support, many locked-in systems provide limited or no integration, while aarna.ml allows for flexible, pluggable integration with popular frameworks such as Run:AI, Ray, and SLURM.

Overall, aarna.ml’s compatibility with existing Kubernetes clusters, advanced features, and flexible architecture make it a forward-looking choice for modern AI infrastructure.

Conclusion

While bundled GPU orchestration platforms may offer initial convenience, they often impede scalability, integration, and agility in the long run. Embracing a Kubernetes-agnostic approach with solutions like aarna.ml GPU CMS provides the flexibility and compatibility essential for modern AI cloud infrastructures.

Apigee APIM Operator for API Administration On Any Gateway

We now provide the Apigee APIM Operator, a lightweight Application Programming Interface Management and API Gateway tool for GKE environments. This release is a critical step towards making Apigee API management available on every gateway, anywhere.

The Kubernetes-based Apigee APIM Operator allows you build and manage API offerings. Cloud-native developers benefit from its command-line interface for Kubernetes tools like kubectl. APIM resources help the operator sync your Google Kubernetes Engine cluster with Apigee.

Advantages

For your business, the APIM Operator offers:

With the APIM Operator, API producers may manage and protect their APIs using Kubernetes resource definitions. Same tools and methods for managing other Kubernetes resources can be used for APIs.

Load balancer-level API regulation streamlines networking configuration and API security and access for the operator.

Kubernetes' role-based access control (RBAC) and Apigee custom resource definitions enable fine-grained access control for platform administrators, infrastructure administrators, and API developers.

Integration with Kubernetes: The operator integrates Helm charts and Custom Resource Definitions to make cloud-native development easy.

Reduced Context Switching: The APIM Operator lets developers administer APIs from Kubernetes, eliminating the need to switch tools.

Use APIM Operator when

API producers who want Kubernetes API management should utilise APIM Operator. It's especially useful for cloud-native Kubernetes developers who want to manage their APIs using the same tools and methods. Our APIM Operator lets Apigee clients add Cloud Native Computing Foundation (CNCF)-based API management features.

limitations

The APIM Operator's Public Preview has certain restrictions:

Support is limited to REST APIs. Public Preview doesn't support GraphQL or gRPC.

The Public Preview edition supports 25 regional or global GKE Gateway resources and API management policies.

A single environment can have 25 APIM extension policies. Add extra APIM extension policies by creating a new environment.

Gateway resources can have API management policies, but not HTTPRoutes.

Public Preview does not support region extension. A setup APIM Operator cannot be moved to different regions.

Meaning for you?

With Kubernetes-like YAML, you can configure API management for many cloud-native enterprises that use CNCF-standardized tooling without switching tools.

APIM integration with Kubernetes and CNCF toolchains reduces conceptual and operational complexity for platform managers and service developers on Google Cloud.

Security and Compliance in Cloud Deployments: A Proactive DevOps Approach

As cloud computing becomes the backbone of modern digital infrastructure, organizations are increasingly migrating applications and data to the cloud for agility, scalability, and cost-efficiency. However, this shift also brings elevated risks around security and compliance. To ensure safety and regulatory alignment, companies must adopt a proactive DevOps approach that integrates security into every stage of the development lifecycle—commonly referred to as DevSecOps.

Why Security and Compliance Matter in the Cloud

Cloud environments are dynamic and complex. Without the proper controls in place, they can easily become vulnerable to data breaches, configuration errors, insider threats, and compliance violations. Unlike traditional infrastructure, cloud-native deployments are continuously evolving, which requires real-time security measures and automated compliance enforcement.

Neglecting these areas can lead to:

Financial penalties for regulatory violations (GDPR, HIPAA, SOC 2, etc.)

Data loss and reputation damage

Business continuity risks due to breaches or downtime

The Role of DevOps in Cloud Security

DevOps is built around principles of automation, collaboration, and continuous delivery. By extending these principles to include security (DevSecOps), teams can ensure that infrastructure and applications are secure from the ground up, rather than bolted on as an afterthought.

A proactive DevOps approach focuses on:

Shift-Left Security: Security checks are moved earlier in the development process to catch issues before deployment.

Continuous Compliance: Policies are codified and integrated into CI/CD pipelines to maintain adherence to industry standards automatically.

Automated Risk Detection: Real-time scanning tools identify vulnerabilities, misconfigurations, and policy violations continuously.

Infrastructure as Code (IaC) Security: IaC templates are scanned for compliance and security flaws before provisioning cloud infrastructure.

Key Components of a Proactive Cloud Security Strategy

Identity and Access Management (IAM): Ensure least-privilege access using role-based policies and multi-factor authentication.

Encryption: Enforce encryption of data both at rest and in transit using cloud-native tools and third-party integrations.

Vulnerability Scanning: Use automated scanners to check applications, containers, and VMs for known security flaws.

Compliance Monitoring: Track compliance posture continuously against frameworks such as ISO 27001, PCI-DSS, and NIST.

Logging and Monitoring: Centralized logging and anomaly detection help detect threats early and support forensic investigations.

Secrets Management: Store and manage credentials, tokens, and keys using secure vaults.

Best Practices for DevSecOps in the Cloud

Integrate Security into CI/CD Pipelines: Use tools like Snyk, Aqua, and Checkov to run security checks automatically.

Perform Regular Threat Modeling: Continuously assess evolving attack surfaces and prioritize high-impact risks.

The Kubernetes control plane orchestrates the entire cluster and ensures that the system’s desired state matches the actual state.

API Server: Serves as the gateway to the cluster. It handles RESTful communication, validates requests, and updates cluster state via etcd.

etcd: A distributed, highly available key-value store that acts as the single source of truth for all cluster metadata.

Controller Manager: Runs various control loops to ensure the desired state of resources (e.g., replicaset, endpoints).

Scheduler: Intelligently places Pods on nodes by evaluating resource requirements and affinity rules.

2. Worker Node Components

Worker nodes host the actual containerized applications and execute instructions sent from the control plane.

Kubelet: Ensures the specified containers are running correctly in a pod.

Kube-proxy: Implements network rules, handling service discovery and load balancing within the cluster.

Container Runtime: Abstracts container operations and supports image execution (e.g., containerd, CRI-O).

3. Pods

The pod is the smallest unit in the Kubernetes ecosystem. It encapsulates one or more containers, shared storage volumes, and networking settings, enabling co-located and co-managed execution.

Kubernetes in Production: Cloud-Native Enablement

Kubernetes is a cornerstone of modern DevOps practices, offering robust capabilities like:

Declarative configuration and automation

Horizontal pod autoscaling

Rolling updates and canary deployments

Self-healing through automated pod rescheduling

Its modular, pluggable design supports service meshes (e.g., Istio), observability tools (e.g., Prometheus), and GitOps workflows, making it the foundation of cloud-native platforms.

Conclusion

Kubernetes is more than a container orchestrator—it's a sophisticated platform for building distributed systems at scale. Mastering its architecture equips professionals with the tools to deliver highly available, fault-tolerant, and agile applications in today’s multi-cloud and hybrid environments.
