This document discusses microservices, an architectural approach where a single application is composed of small, independent services that communicate with each other. Microservices allow for independent development and deployment of each service by different teams using various programming languages and tools. However, microservices also introduce operational overhead, require substantial DevOps skills, and make testing and asynchronous communication more challenging.

Liferay as a Microservice Platform
This document discusses Liferay as a microservice platform. It begins by describing some issues with monolithic applications, such as high complexity, limited scalability and reusability. It then introduces microservices as an approach to break applications into independently deployable services. While microservices reduce complexity within each component, they can increase operational overhead and introduce new challenges around network communication and coordination. The document argues that Liferay's use of OSGi addresses many microservice goals while avoiding some of the operational overhead, and that its modular architecture provides a natural path for applications to evolve from monoliths to microservices over time.
Discussion About Microservices Architecture

Microservices
Microservices architecture is an approach to developing a single application as a suite of small services that communicate with each other using lightweight mechanisms like REST APIs. Each service runs in its own process and communicates through APIs, allowing independent scaling of services. This contrasts with monolithic architecture where all application components are deployed together in one process. Microservices provide benefits like independent scalability, fault isolation, and faster development cycles compared to monolithic applications. Common technologies used in microservices include API gateways, service discovery, configuration management, distributed logging, and messaging.
Microservices
• The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms.
• To start explaining the microservice style it's useful to compare it to the monolithic style: a monolithic application built as a single unit (all our past projects and current ones are monolithic).
• We cannot say there is a formal definition of the microservices architectural style, but we can attempt to describe what we see as common characteristics for architectures that fit the label.
• Knowing when to use microservices, its benefits, and its costs are also important.
• In the demo, it is shown how to build simple microservice applications using Spring.

[WSO2Con EU 2017] Microservices for Enterprises
Microservice architecture (MSA) is fast becoming a popular architecture pattern in today’s agile enterprises. Its iterative architecture and development methodologies are attracting the interest of architects who need continuous delivery to fulfill business needs. But, is every characteristic of MSA new or even pragmatic? Can MSA alone help you solve your enterprise challenges? This session will explore how middleware plays a key role in successful MSA-based implementations.
Understanding Microservice Architecture WSO2Con Asia 2016
Today many organizations are leveraging microservice architecture (MSA), which is becoming increasingly popular because of its many potential advantages. MSA itself is divided into two areas – inner and outer architectures – which require separate attention. Moreover, MSA requires a certain level of developer and devops experience too. This talk will be an awareness session about MSA and will also discuss WSO2′s strategic initiatives in both the platform level and WSO2 MSF4J framework level.
Microservices
The document discusses microservices and provides examples of how to implement them. Some key points:
Microservices allow for increased agility, minimize failures, and enable building faster and more focused applications. Each service is independent, observable, and focuses on a specific business domain. They are resilient through replication and can scale horizontally.
Case studies demonstrate using microservices for a central data repository and rules engine. Challenges include developing DevOps talent and partitioning data and services for horizontal scaling. Automation is achieved through tools like Jenkins, Git, and Kubernetes.
Microservices enable easier and faster development but require DevOps expertise and eventual consistency instead of transactions. They are well-suited for elastic cloud environments.

Introduction to Microservices.pdf
Microservices are an approach to application development where a large application is broken into smaller, independent services that communicate through well-defined interfaces. Each service focuses on a specific business goal and can be developed and deployed independently. Key characteristics of microservices include high maintainability, loose coupling, independent deployability, organization around business capabilities, and decentralized ownership. Transitioning from a monolithic architecture to microservices introduces challenges around inter-process communication, distributed transactions, service discovery, and increased need for automation. A microservices ecosystem typically includes load balancers, service discovery, API gateways, configuration management, monitoring, containerization, and circuit breakers.
Introduction to Microservices_Architecture.pptx
The document discusses an agenda for an introduction to microservices training. It will cover topics like microservices principles, comparing monolithic and service-oriented architectures to microservices, when to use microservices, challenges of microservices, tools for building microservices, API gateways, and design patterns for microservices. The training will define microservices and explain their benefits and drawbacks compared to traditional architectures.
Micro services overview
Microservices are a software development technique—a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services. In a microservices architecture, services are fine-grained and the protocols are lightweight.
Serverless & Microservices Architecture
Martin Fowler defines microservices as an architectural style where single applications are developed as independent services that communicate with each other via lightweight mechanisms often using HTTP. Microservices are built around business capabilities, independently deployable, and owned by small teams. When developing microservices, continuous integration, deployment and automated testing are required. An API is not the same as a microservice - APIs expose data and behavior via contracts while microservices implement business capabilities. Microservices should only be used for large, complex systems that are hard to manage as a monolith.
DevOps-training-in-chandigarh-Join-now--
Microservices and DevOps form a powerful alliance for modern software development.Reiterate that microservices and DevOps are not just technology choices; they represent a fundamental shift in the way we build and deliver software. By embracing these approaches, organizations can accelerate innovation and achieve long-term success in today's fast-changing digital landscape.
MICROSERVICES ARCHITECTURE unit -2.pptx
The document discusses microservices architecture and monolithic architecture. It defines microservices as an architectural style where applications are composed of small, independent services that communicate over well-defined APIs. This allows for independent deployability and scalability of individual services. The document contrasts this with monolithic architecture, which packages an entire application into a single deployable unit with tight coupling between components.
Micro services extra note
Microservices is an approach to application development where a large application is broken down into smaller, independent modules called microservices. Each microservice runs its own processes, manages its own database, and communicates through well-defined interfaces. This allows each service to be developed, deployed, and managed independently. While microservices provide advantages like agility and scalability, challenges include getting organizations to understand the distributed nature of applications and to break existing systems into modular components.

Microservices
Microservices are an architectural style that structures an application as a collection of loosely coupled services organized around business capabilities. Each microservice focuses on completing a single task and communicates through APIs. This contrasts with a monolithic architecture where all application components are in one codebase. Microservices provide benefits like independence, scalability, and flexibility but introduce challenges around coordination and complexity.
A Primer to Containerization & Microservices
This document provides an overview of containerization and microservices. It defines microservices as an architectural style involving independently deployable small services. Containerization is discussed as a way to deploy microservices using lightweight isolated environments. Key benefits of microservices like scalability, flexibility and resilience are covered. Docker is introduced as a popular tool for containerization, allowing packaging and sharing of applications.
Microservice's in detailed
This document provides an overview of microservices, including:
- What microservices are and how they differ from monolithic architectures and SOA.
- Common microservice design patterns like aggregator, proxy, chained, and asynchronous messaging.
- Operational challenges of microservices like infrastructure, load balancing, monitoring.
- How microservices compare to SOA in terms of independence, scalability, and technology diversity.
- Key security considerations for microservices related to network access, authentication, and operational complexity.
Microservice Architecture Software Architecture Microservice Design Pattern
Architecture serves as a blueprint for a system, providing abstraction to manage complexity and coordination among components. It defines a structured solution meeting requirements while optimizing qualities like performance and security. Microservices are small, independent, loosely coupled services written by small teams, deployed independently using APIs. They improve build/deploy speed and scalability over monolithic architectures.
Microservice Architecture
The document discusses microservices architecture. It defines microservices as an approach to developing a single application as a suite of small services that communicate with each other via lightweight mechanisms like HTTP APIs. Each service runs independently, is built around business capabilities, and can be deployed independently. There is minimal centralized management of services, which can use different programming languages and data storage technologies.

Key characteristics include organizing services around business capabilities, treating applications as products rather than projects, designing for failure, and decentralizing governance and data. Services communicate through lightweight protocols like HTTP and messaging and aim to be smart endpoints with dumb pipes. Infrastructure is automated through testing, deployment pipelines and monitoring for failure recovery. While microservices add complexity, the approach aims to improve scalability, flexibility and resilience over traditional monolithic architectures.

Etl elt simplified
The document discusses the pros and cons of staging data warehouses using Extract, Transform, Load (ETL) versus Extract, Load, Transform (ELT). Some key advantages of ETL include reducing development time by only extracting relevant data, simplifying administration through targeted data loads, and flexibility in tool selection. However, ETL can limit flexibility for future requirements and necessitate additional hardware. ELT enables project management in smaller chunks, flexibility for future needs, and risk minimization through isolated processes, but availability of mature tools is still limited as the technology is emerging.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
