In this tutorial, you’ll learn how to read Google Docs with Spring Boot application using google docs api. We’ll guide you through setting up OAuth 2.0, accessing the Docs API, and retrieving document data programmatically. Create a Google Cloud project In the Google Cloud console, go to menu > IAM & Admin > Create a Project.Enter Project Name and Create. […]

In this section, we’re going to look at the standards and technologies that are available to make our microservices visible so that we can make visible the data and functionality that our microservices provide to everyone in our organization. One of the ways of doing this is by exposing a special endpoint using a framework

Automation in Microservices is another key design principle for our architecture, and the main thinking behind this is to use tools for automated hosting, testing, and deployment. Let’s deep dive in different automation strategies. On-Demand Hosting By automated hosting, we mean once we have our software architecture perfected, i.e. our production environment perfected, we want

Observability Design Principle is key for our microservices architecture because this architectural style gives you an architecture which is complex with many moving parts. Therefore, we need the ability not only to see the health of our workflows, i.e. our logical transactions, but we also need the ability to see the health of all our

Resiliency design principle of mircroservices is all about making our software reliable and available and ensuring that if we do have any failures within our back‑end microservices, each service fails fast and there’s alternate functionality so that the user doesn’t face any disruption. Let’s discuss the various steps to develop a resilient system Design for

In the Visitor pattern, we employ a visitor class to alter the execution algorithm of an element class. This flexibility allows the element’s execution algorithm to adapt as the visitor changes. This pattern falls under the behavior pattern category. In accordance with this pattern, an element object must accept the visitor object, enabling the visitor
The Template Method is a behavioral design pattern that defines a blueprint for an algorithm in a superclass but allows specific steps of the algorithm to be overridden by subclasses without changing its core structure. Consider developing a data mining application that analyzes corporate documents in various formats (PDF, DOC, CSV) to extract meaningful data.
The State Pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The pattern encapsulates states as separate classes and delegates the state-specific behavior to these classes. This makes it easy to add new states and modify the behavior of an object without altering its structure.
The Mediator pattern, also known as the Intermediary or Controller, helps manage communication between different objects. It stops objects from talking to each other directly and makes them talk only through a mediator. This keeps things more organized and prevents messy connections between objects. In air traffic control systems multiple aircraft need to coordinate their
