Study Notes

Key Advantages of Microservices Architecture

Microservices architecture allows independent development, deployment, and scaling of services, enhancing flexibility and speed in software development.
It promotes fault isolation; a failure in one microservice does not impact the entire application, improving reliability and resilience.

Main Difference Between Architectures

Microservices architecture divides applications into smaller, loosely coupled services, each responsible for specific functions, while monolithic architecture builds applications as a single, indivisible unit.
In microservices, technologies and programming languages can vary across services, whereas monolithic architecture typically uses a single technology stack.

Purpose of Client-Side User Interface in Monolithic Applications

The client-side user interface is the front end through which users interact with the application, responsible for presenting data and capturing user input.
It directly communicates with the back end to fetch and display information, often leading to performance bottlenecks in monolithic designs.

Database in Enterprise Applications Context

A database acts as the central repository for storing and managing data used across various components of the enterprise application.
In monolithic applications, a single database is often used, but microservices may implement individual databases per service to increase autonomy.

Serving a Single User Request in Microservices-Based Applications

A microservices-based application processes a single user request by routing it through multiple services, each handling a specific business logic part.
It leverages asynchronous communication, where services collaborate and respond independently, often resulting in improved performance and scalability.

Microservice Architecture

Microservice architecture involves dividing application responsibilities into smaller, focused services.
Each microservice operates autonomously with loosely coupled dependencies, allowing independent development, testing, and release.
Services communicate internally to exchange necessary information for results.

Separation of Concerns (SoC)

SoC is a design principle that separates implementation into distinct layers, each addressing a unique concern.
In microservices, SoC helps identify business capabilities and cross-cutting concerns for autonomous service design.

Models

Models define the structure of data exchanged in and out of a microservice.
Data transformation involves serialization and deserialization processes during communication.
Within the service layer, models exist as in-memory objects.

SDK Layer

SDKs can be created for specific programming languages to promote easier API adoption.

API Gateway Layer

API gateways act as proxies for APIs, enabling functionalities such as security, subscription services, and performance monitoring.
Features include API key requirements, throttling, and data transformation between formats (e.g., XML to JSON).

Protocol Layer

This layer specifies the network protocol (e.g., HTTP or TCP) and communication methods (e.g., SOAP/WSDL or ReST) for the microservice.

Service Layer

The service layer contains the core operations, including business rules, workflows, and calculations required for microservice functionality.
It interacts with the data access layer for tasks like data persistence and caching.

Data Access Layer

The data access layer manages interactions with various data storage services, such as caching systems, relational databases, and message queues.

Store

Refers to data persistence mechanisms, which can include databases, files, etc.

Automation

Encompasses development lifecycle practices such as continuous integration and continuous delivery for streamlined software updates.
