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.

A Beginner’s Guide to RESTful API Design

RESTful APIs are the backbone of modern web and mobile applications. Whether you're building the backend for a web service, a mobile app, or a microservice architecture, understanding how to design a RESTful API is essential. In this guide, we’ll walk you through what REST is and how to structure APIs that are scalable, maintainable, and easy to use.

What is a RESTful API?

REST stands for Representational State Transfer. It's an architectural style that uses standard HTTP methods (GET, POST, PUT, DELETE) for communication between clients and servers. A RESTful API exposes data and services over the web using URLs, returning responses typically in JSON format.

Core Principles of RESTful API Design

Statelessness: Each request should contain all the information needed to process it. The server does not store client session data.

Resource-Based: Data is represented as resources (e.g., /users, /products).

Use of HTTP Methods: Use standard HTTP verbs for actions: GET (read), POST (create), PUT/PATCH (update), DELETE (remove).

Uniform Interface: Consistent structure and naming conventions help developers understand and use your API easily.

Representation: Resources are typically represented using JSON or XML.

Best Practices for RESTful API Design

1. Use Nouns in URIs

URIs should represent resources, not actions. Example:✅ /users❌ /getUsers

2. Use HTTP Methods Correctly

GET /users → Get list of users

GET /users/1 → Get user with ID 1

POST /users → Create a new user

PUT /users/1 → Update user with ID 1

DELETE /users/1 → Delete user with ID 1

3. Return Proper HTTP Status Codes

200 OK → Successful request

201 Created → Resource created successfully

400 Bad Request → Client error

401 Unauthorized → Authentication failed

404 Not Found → Resource doesn’t exist

500 Internal Server Error → Server-side error

4. Use JSON as the Response Format

JSON is the most widely used and supported format. It’s readable by both humans and machines.

5. Version Your API

Always version your APIs to avoid breaking changes for clients when you update your codebase./api/v1/users

6. Use Pagination for Large Collections

For endpoints that return many items, use query parameters for pagination:/users?page=2&limit=20

7. Include Error Messages

Return helpful error messages to guide developers on how to fix their request: { "error": "Invalid input", "details": "Email address is required" }

8. Secure Your API

Use HTTPS to encrypt data in transit.

Implement authentication (e.g., OAuth2, JWT).

Validate inputs to prevent injection attacks.

Tools for API Development and Testing

Postman: Test and document your APIs.

Swagger/OpenAPI: Generate interactive API documentation.

Insomnia: Alternative to Postman for API testing.

Conclusion

Designing a RESTful API isn't just about making something that works — it's about making it intuitive, reliable, and secure. By following the principles and best practices outlined here, you'll create APIs that developers love to use and that can scale with your application.

Weak API Authentication in Laravel: How to Secure It

Introduction

API authentication is a critical aspect of securing web applications. In Laravel, APIs allow developers to connect with the backend while keeping things modular and efficient. However, when API authentication is weak or poorly implemented, it leaves the door open for attackers to exploit sensitive data.

In this post, we’ll explore the risks of weak API authentication in Laravel, how to identify vulnerabilities, and ways to secure your API endpoints. We’ll also guide you through a coding example and introduce a free tool for a website security test to help you identify API vulnerabilities on your site.

Why Weak API Authentication Is Dangerous

APIs are a primary target for cybercriminals due to the sensitive data they expose. When authentication methods are weak, such as using insecure or predictable tokens, attackers can easily bypass security mechanisms and gain unauthorized access to your backend systems.

Here’s why weak API authentication is dangerous:

Data Breaches: Hackers can access user data, financial information, or any sensitive data stored in your database.

Unauthorized API Calls: Without proper authentication, malicious users can make API requests on behalf of authenticated users.

Denial of Service Attacks: Exploiting weak authentication can allow attackers to overload your systems or take them down entirely.

Common Causes of Weak API Authentication

Some common causes of weak API authentication include:

Using Default Tokens: Laravel provides several ways to authenticate APIs, but many developers still use the default tokens or insecure methods.

No Token Expiration: Not setting an expiration time for API tokens can lead to long-term vulnerabilities.

Insecure Password Storage: If you store passwords in plain text or use weak hashing algorithms, hackers can easily retrieve them.

Improper Rate Limiting: Failing to limit the number of API requests from a user can lead to brute-force attacks.

How to Secure API Authentication in Laravel

Here, we’ll walk you through securing your API authentication in Laravel, step by step, using modern techniques.

1. Use Laravel Passport for OAuth Authentication

Laravel Passport provides a complete OAuth2 server implementation for your Laravel application. It is the most secure and robust way to handle API authentication.

To install Laravel Passport, follow these steps:

composer require laravel/passport php artisan migrate php artisan passport:install

After installation, you need to configure the AuthServiceProvider to use Passport:

use Laravel\Passport\Passport; public function boot() { Passport::routes(); }

Then, update your api guard in config/auth.php to use Passport:

'guards' => [ 'api' => [ 'driver' => 'passport', 'provider' => 'users', ], ],

Now, you can authenticate users using OAuth tokens, which provides a much higher level of security.

2. Enable Token Expiration

Another important step is ensuring that API tokens expire after a certain period. By default, tokens generated by Passport are long-lived, but you can customize their expiration time.

To set token expiration, update the config/passport.php file:

'personal_access_tokens_expire_in' => now()->addDays(7),

This will ensure that tokens expire after 7 days, requiring users to re-authenticate.

3. Use Strong Hashing for Passwords

Make sure that you store passwords securely using bcrypt or Argon2 hashing. Laravel automatically hashes passwords using bcrypt, but you can configure it to use Argon2 as well in config/hashing.php:

'driver' => 'argon2i',

4. Implement Rate Limiting

To prevent brute-force attacks, you should implement rate limiting for your API. Laravel has a built-in rate limiting feature that you can enable easily in routes/api.php:

Route::middleware('throttle:60,1')->get('/user', function (Request $request) { return $request->user(); });

This will limit the API requests to 60 per minute, helping to prevent excessive login attempts.

Testing Your API Security

After implementing the above security measures, it's important to test your API for vulnerabilities. Use our Website Vulnerability Scanner to check your website’s API security and identify any weaknesses in your authentication methods.

MCP Toolbox for Databases Simplifies AI Agent Data Access

AI Agent Access to Enterprise Data Made Easy with MCP Toolbox for Databases

Google Cloud Next 25 showed organisations how to develop multi-agent ecosystems using Vertex AI and Google Cloud Databases. Agent2Agent Protocol and Model Context Protocol increase agent interactions. Due to developer interest in MCP, we're offering MCP Toolbox for Databases (formerly Gen AI Toolbox for Databases) easy to access your company data in databases. This advances standardised and safe agentic application experimentation.

Previous names: Gen AI Toolbox for Databases, MCP Toolbox

Developers may securely and easily interface new AI agents to business data using MCP Toolbox for Databases (Toolbox), an open-source MCP server. Anthropic created MCP, an open standard that links AI systems to data sources without specific integrations.

Toolbox can now generate tools for self-managed MySQL and PostgreSQL, Spanner, Cloud SQL for PostgreSQL, Cloud SQL for MySQL, and AlloyDB for PostgreSQL (with Omni). As an open-source project, it uses Neo4j and Dgraph. Toolbox integrates OpenTelemetry for end-to-end observability, OAuth2 and OIDC for security, and reduced boilerplate code for simpler development. This simplifies, speeds up, and secures tool creation by managing connection pooling, authentication, and more.

MCP server Toolbox provides the framework needed to construct production-quality database utilities and make them available to all clients in the increasing MCP ecosystem. This compatibility lets agentic app developers leverage Toolbox and reliably query several databases using a single protocol, simplifying development and improving interoperability.

MCP Toolbox for Databases supports ATK

The Agent Development Kit (ADK), an open-source framework that simplifies complicated multi-agent systems while maintaining fine-grained agent behaviour management, was later introduced. You can construct an AI agent using ADK in under 100 lines of user-friendly code. ADK lets you:

Orchestration controls and deterministic guardrails affect agents' thinking, reasoning, and collaboration.

ADK's patented bidirectional audio and video streaming features allow human-like interactions with agents with just a few lines of code.

Choose your preferred deployment or model. ADK supports your stack, whether it's your top-tier model, deployment target, or remote agent interface with other frameworks. ADK also supports the Model Context Protocol (MCP), which secures data source-AI agent communication.

Release to production using Vertex AI Agent Engine's direct interface. This reliable and transparent approach from development to enterprise-grade deployment eliminates agent production overhead.

Add LangGraph support

LangGraph offers essential persistence layer support with checkpointers. This helps create powerful, stateful agents that can complete long tasks or resume where they left off.

For state storage, Google Cloud provides integration libraries that employ powerful managed databases. The following are developer options:

Access the extremely scalable AlloyDB for PostgreSQL using the langchain-google-alloydb-pg-python library's AlloyDBSaver class, or pick

Cloud SQL for PostgreSQL utilising langchain-google-cloud-sql-pg-python's PostgresSaver checkpointer.

With Google Cloud's PostgreSQL performance and management, both store and load agent execution states easily, allowing operations to be halted, resumed, and audited with dependability.

When assembling a graph, a checkpointer records a graph state checkpoint at each super-step. These checkpoints are saved in a thread accessible after graph execution. Threads offer access to the graph's state after execution, enabling fault-tolerance, memory, time travel, and human-in-the-loop.

Microservices Programming

Microservices architecture is revolutionizing the way modern software is built. Instead of a single monolithic application, microservices break down functionality into small, independent services that communicate over a network. This approach brings flexibility, scalability, and easier maintenance. In this post, we’ll explore the core concepts of microservices and how to start programming with them.

What Are Microservices?

Microservices are a software development technique where an application is composed of loosely coupled, independently deployable services. Each service focuses on a specific business capability and communicates with others through lightweight APIs, usually over HTTP or messaging queues.

Why Use Microservices?

Scalability: Scale services independently based on load.

Flexibility: Use different languages or technologies for different services.

Faster Development: Small teams can build, test, and deploy services independently.

Resilience: Failure in one service doesn't crash the entire system.

Better Maintainability: Easier to manage, update, and test smaller codebases.

Key Components of Microservices Architecture

Services: Individual, self-contained units with specific functionality.

API Gateway: Central access point that routes requests to appropriate services.

Service Discovery: Automatically locates services within the system (e.g., Eureka, Consul).

Load Balancing: Distributes incoming traffic across instances (e.g., Nginx, HAProxy).

Containerization: Deploy services in isolated environments (e.g., Docker, Kubernetes).

Messaging Systems: Allow asynchronous communication (e.g., RabbitMQ, Apache Kafka).

Popular Tools and Frameworks

Spring Boot + Spring Cloud (Java): Full-stack support for microservices.

Express.js (Node.js): Lightweight framework for building RESTful services.

FastAPI (Python): High-performance framework ideal for microservices.

Docker: Container platform for packaging and running services.

Kubernetes: Orchestrates and manages containerized microservices.

Example: A Simple Microservices Architecture

User Service: Manages user registration and authentication.

Product Service: Handles product listings and inventory.

Order Service: Manages order placement and status.

Each service runs on its own server or container, communicates through REST APIs, and has its own database to avoid tight coupling.

Best Practices for Microservices Programming

Keep services small and focused on a single responsibility.

Use versioned APIs to ensure backward compatibility.

Centralize logging and monitoring using tools like ELK Stack or Prometheus + Grafana.

Secure your APIs using tokens (JWT, OAuth2).

Automate deployments and CI/CD pipelines with tools like Jenkins, GitHub Actions, or GitLab CI.

Avoid shared databases between services — use event-driven architecture for coordination.

Challenges in Microservices

Managing communication and data consistency across services.

Increased complexity in deployment and monitoring.

Ensuring security between service endpoints.

Conclusion

Microservices programming is a powerful approach to building modern, scalable applications. While it introduces architectural complexity, the benefits in flexibility, deployment, and team autonomy make it an ideal choice for many large-scale projects. With the right tools and design patterns, you can unlock the full potential of microservices for your applications.

Oracle Apex Oauth2 Example

OAuth2 in Oracle APEX: A Practical Guide and Example

OAuth2 is a contemporary and secure authorization framework that allows third-party applications to access protected resources on behalf of a user. By implementing OAuth2 in Oracle APEX, you can provide controlled access to your APEX application’s data and functionality, enabling seamless integration with other services.

Why use OAuth2 with APEX?

Enhanced Security: OAuth2 offers a robust security layer compared to traditional username and password-based authentication. It uses tokens rather than directly passing user credentials.

Fine-grained Access Control: OAuth2 allows you to define specific scopes (permissions) determining the access level granted to third-party applications.

Improved User Experience: Users can conveniently authorize applications without repeatedly sharing their primary credentials.

Prerequisites

A basic understanding of Oracle APEX development

An Oracle REST Data Source (ORDS) instance, if you want to integrate with ORDS-defined REST APIs

Steps for Implementing OAuth2 in Oracle APEX

Create an OAuth2 Client:

Within your APEX workspace, navigate to Shared Components -> Web Credentials.

Click Create and select the OAuth2 Client type.

Provide a name, ID, client secret, and any necessary authorization scopes.

Obtain an Access Token:

The method for obtaining an access token will depend on the OAuth2 flow you choose (e.g., Client Credentials flow, Authorization Code flow).

Utilize the Access Token:

Include the access token in the Authorization header of your API requests to protected resources. Use the format: Bearer .

Example: Accessing an ORDS-based REST API

Let’s assume you have an ORDS-based REST API endpoint for fetching employee data that requires OAuth2 authentication. Here’s how you would configure APEX to interact with it:

Create a REST Data Source:

Go to Shared Components -> REST Data Sources.

Set the authentication type to OAuth2 Client Credentials Flow.

Enter your OAuth2 token endpoint URL, client ID, and client secret.

Use the REST Data Source in Your APEX Application:

Create APEX pages or components that utilize the REST Data Source to fetch and display employee data. APEX will automatically handle obtaining and using the access token.

Additional Considerations

Access Token Expiration: OAuth2 access tokens usually have expiration times. Implement logic to refresh access tokens before they expire.

OAuth2 Flows: Choose the most suitable OAuth2 flow for your integration use case. The Client Credentials flow is often used for server-to-server integrations, while the Authorization Code flow is more common for web applications where a user is directly involved.
