REST architecture (Representational State Transfer)
REST architecture, which stands for Representational State Transfer, is a widely adopted design model for communication systems on the web. It is known for its simplicity and efficiency, and is widely used to build web services, mobile applications and system integrations. This section provides an overview of the REST architecture, its fundamental principles and how it has influenced the way systems interact in the modern web era.
Fundamental Principles of REST Architecture:
Resources and Unique Identifiers (URIs): In REST architecture, everything is treated as a resource. Each resource is identified by means of a URI (Uniform Resource Identifier), which is unique and provides a means of accessing the resource.
HTTP methods: Communication in the REST architecture is carried out using HTTP methods such as GET (to retrieve information), POST (to create resources), PUT (to update resources) and DELETE (to remove resources). Each method corresponds to a specific operation on a resource.
Representations: Resources in a REST system can have various representations, such as XML, JSON, HTML, among others. Clients request the desired representation via the request headers.
Stateless: REST systems are stateless, which means that each request from a client to the server must contain all the information needed to understand and process the request. The server does not keep information about the state of the client's session.
Client-Server communication: The REST architecture promotes a clear separation between the client and the server. The client is responsible for the user interface and user interaction, while the server takes care of data processing and storage.
Layers: The REST architecture supports division into layers, which allows different components of a system to be scalable and independent.
Advantages of REST Architecture:
Simplicity: The resource-based approach and HTTP methods make REST architecture easy to understand and implement.
Scalability: The separation of layers and the sessionless state facilitate the scalability of REST systems.
Reuse: The REST architecture allows resources and services to be easily reused in different parts of a system or in different systems.
Wide Adoption: REST architecture is widely adopted in the industry, which makes it easy to integrate with other systems and services.
Performance: The lightweight nature of REST requests and responses generally results in good performance.
Design of the workflow used to version Code Tech products.
This versioning process for products has the following structure:
Production: Restricted environment, where only the administrator has access. The information in this environment has been approved by the administrators.
Pre-Production: Quality environment, where quality analysts will validate the source code that will go into production. This environment is for emerging code, where a faster delivery flow is required.
Homologation: Quality environment, where quality analysts will validate the source code that will go into production. This environment is for functionalities that will be delivered at the end of a development cycle. The information in this environment will be constantly updated as pre-production updates and development delivers.
Bugfixes will be made in this environment.
Development: This environment is for creating new features, used by developers.
Amazon Web Services (AWS) API Gateway is a powerful solution that plays a key role in the cloud computing landscape. It enables organizations to efficiently create, manage and publish APIs (Application Programming Interfaces), making it easier than ever to connect systems and deliver innovative services to customers and partners. In this article, we'll explore the AWS API Gateway and its remarkable capabilities.
What is the AWS API Gateway?
AWS API Gateway is a fully managed API management service designed to simplify the creation, publication and maintenance of APIs. It acts as an intermediary layer between client applications and services behind the scenes, facilitating controlled and secure access to application functionality and data.
Main benefits:
Easy API creation: With the AWS API Gateway, creating APIs becomes a simplified task. You can design your APIs from scratch or import existing definitions, saving time and effort.
Automatic Scalability: The service is highly scalable, ensuring that your APIs can handle traffic spikes without additional effort.
Traffic Management: The Gateway allows you to route requests to different versions of a service, making it possible to gradually deploy updates and tests.
Integrated Security: The service offers integrated authentication and authorization, protecting your APIs from unauthorized access.
Monitoring and Analysis: The AWS API Gateway provides detailed monitoring and analysis capabilities, allowing you to track the performance and utilization of your APIs.
Integration with Other AWS Services: It is seamlessly integrated with other AWS services, such as AWS Lambda, Amazon S3, and AWS IAM, making it easy to build highly integrated solutions.
Common Use Cases:
Web Service APIs: The AWS API Gateway is often used to create web service APIs, allowing client applications to communicate with cloud services.
Mobile Applications: It is a popular choice for creating APIs for mobile applications, providing a reliable interface for interactions between applications and cloud services.
IoT (Internet of Things): It is used to create APIs that enable communication between IoT devices and back-end servers.
Private APIs: It is also possible to create private APIs to enable secure communication between different components of a system.
