Reading Time: 5 minutes Step 1 : Create an Amazon EC2 Instance This EC2 instance is for ssh tunneling to aws documentDB cluster and application running locally. By using cmd: chmod 400 keypair-name :- Gives the user read permission, and removes all other permission. Step 2 : Create an Amazon DocumentDB Cluster Step 3 : Create a Java application with the Axon framework for Event-Sourcing.(Aws DocumentDB as event Continue Reading
Reading Time: 3 minutes In this blog, We will discuss axon framework terminologies and servers we’ll be talking about part one the structure of an axon application but prior to diving into that, we’ll first have a couple of the axon concepts which come into play when you’re working with an axon application. You might want to learn more about like command query responsibility segregation or using commands events Continue Reading
Reading Time: 2 minutes In this blog, we will cover AxonIQ Initializr. What is AxonIQ Initializr The AxonIQ Initializr is a web application that creates an Axon project structure for you. It doesn’t generate any application code, but it will give you a solid project structure, offering either a Maven or a Gradle build specification to suit your needs. Why Initialzr Sometimes the most challenging part of any project is getting Continue Reading
Reading Time: 3 minutes AxonIQ Server Axon server is a message broker for commands, events, and queries. It’s a proposed pre-build events store. It’s easy to set up, just download the jar or docker image and start without any configuration. Let’s take three nodes server cluster running and three applications, connected to Axon server nodes. The application can be associated with different server nods as we can see in Continue Reading
Reading Time: 4 minutes If you want to build Microservices, You may prefer Axon, a Java-based framework. It provides utility to implement CQRS (Command Query Responsibility Segregation), Event Sourcing, and DDD (Domain Driven Design) architectural patterns while developing a software application. Axon facilitates the implementation of Command Handling, Event Routing, Event Sourcing, Snapshotting, and many more building blocks. It has very friendly APIs to use these implementations and build Continue Reading
Reading Time: 4 minutes Introduction One of the most common discussion points that come up regularly in interactions with Customers/Prospects/Forums is how does Axon compare to Apache Kafka? Can one do the job of the other? Are they complementary to each other? Can they work together? Does Axon provide any capabilities to work with Kafka? Apache Kafka is a very popular system for publishing and consuming events. Its architecture Continue Reading
Reading Time: 3 minutes Axon and Kafka are used for different purposes, Axon is used for Event-Driven Architecture and provides the application-level support for domain modeling and Event Sourcing, as well as the routing of Commands and Queries, while Kafka serves as an Event Streaming system. The basic fundamental of Axon is to implement CQRS and Event Sourcing-based architecture. With the help of this, we can design & develop Continue Reading
Reading Time: 3 minutes Prerequisites: If you are reading this blog I assume you are already familiar with the Axon Framework basics. If not, please visit “Axon Part 1: An Introduction to Axon Framework” to get started with Axon. Introduction: Initializers are the tools that help us start off with our project right away by automating some of the tasks which we need to go through every time we Continue Reading
Reading Time: 4 minutes This is Part 2 of an ongoing series of blogs explaining Axon Framework. This blog is going to take you a step ahead and help you know more about the application directory structure to be followed. Also we’ll understand the spring boot integration for Axon. Additionally, this blog will have a quick Axon Server Setup Guide. Prerequisites: Go through the Axon Part 1 – An Continue Reading
Reading Time: 3 minutes This is the first part of an ongoing series of blogs explaining Axon Framework. This blog will help you get started with axon and get a basic understanding of the same. Prerequisites Understanding Axon requires a basic knowledge of a few Axon concepts. Those are: Microservices Command Query Responsibility Segregation(CQRS) Commands, Events and Queries Domain Driven Design(DDD) Event Sourcing SAGA Design Pattern Introduction Problem: The Continue Reading
Reading Time: 4 minutes I hated biology in my school days and loved mathematics. After a long period of time I get to learn something which combines both mathematics and biology together, that is Artificial Neural Network short for ANN, inspired by biological Neural network. Though you might find it weird, that is how I would like to define the artificial neural network. When we say biology here, it Continue Reading
