Dive deep into Spring Boot Architecture


Spring Boot is built on top of the Spring framework. Spring Boot helps you to build production grade application easily.

Spring Boot has a layered architecture. Which means each layer directly communicate with it below or upper layer.


Spring Boot layers


  • Presentation Layer

v  Presentation layer is having a responsibility of handling HTML requests and authenticate the requests. It also translates the JSON parameters to objects

  • Business Layer

The Power of ChatGPT and Whisper Models

A Deep Dive into Natural Language Processing Natural Language Processing (NLP) has seen a significant boost in recent years due to advancements in artificial intelligence and machine learning. Two models that have shown remarkable success in NLP are ChatGPT and Whisper. In this article, we will delve into the power of these models and their applications in the field of NLP. ChatGPT is a transformer-based language model developed by OpenAI that uses unsupervised learning to predict the next word in a sentence based on the context of previous words. ChatGPT is a generative model that is trained on large datasets of text, such as books and articles, and can be fine-tuned for specific tasks, such as question-answering or dialogue generation. ChatGPT is known for its ability to produce human-like text, making it an ideal tool for applications such as chatbots, content creation, and language translation. Whisper, on the other hand, is a paraphrasing model developed by Google that is based on

DevOps practices and tools

DevOps is a set of practices and principles that aims to bring together the development and operations teams in software development projects. It focuses on improving collaboration, communication, and automation between these two groups to achieve faster, more efficient software delivery. The principles of DevOps include the following: Collaboration : Collaboration between development and operations teams to improve communication and alignment on project goals. Automation : The use of automation tools to streamline software development and delivery processes, reducing manual intervention and errors. Continuous Integration and Continuous Delivery (CI/CD) : Continuous integration involves integrating code changes into a shared repository frequently, while continuous delivery involves releasing new software versions to production regularly. Monitoring : Continuous monitoring of software performance and user feedback to identify and fix issues quickly. The practices of DevOps include: Agil
