CQRS - Event Sourcing Architecture Patterns in Building Event Driven Systems

CQRS - Event Sourcing Architecture Patterns enables us build efficient Event Driven Systems. 
If any organization wants to build Event Based systems, they should adhere to the principles defined by CQRS, Event Sourcing & Domain Driven Design principles. The following videos makes you to better understand how these design patterns and can help you in dealing with performance, validation, parallel updates in the data and events. And also explained how pessimistic locking and optimistic locking works with respect to Event Driven Architecture. By following the principles of these architectures you can build powerful microservices which can be easily scalable and better in performance and you will not be ended with building monolithic application.

Checkout the video on deep dive on these 2 patterns complement each other to build efficient Event Driven Systems. If you like the video, subscribe to channel and share with your friends and colleagues.

How To Create Docker Image of Spring Boot App without Dockerfile?

Generally to create a docker image for Spring application or any other app, we create a dockerfile and we run docker build command. But from Spring 2.3 version onwards we no need to write any dockerfile for our application. Since cloud-native buildpacks support is natively added in Spring 2.3 version onwards. This will reduce a lot overhead for developer to put more focus on business logic implementation.

In the following video I explained how we can create a docker image using Spring 2.3 version. Checkout the video below. If you like the video, subscribe to it and share with friends and colleagues.

Spring Boot with Kafka Producer and Consumer Example

We can utilize ready made templates provided by Spring Boot framework to connect with Kafka to write messages and read from with Kafka Producer and Kafka Consumer.

In the following you will see complete demo of building Spring Boot with Kafka Producer and Kafka Consumer classes to write and read data to and from Kafka topic. And also we will learn how to dockerize Kafka and run it with Docker Compose.

Just check the following video. If you like the video like it and subscribe to channel: https://www.youtube.com/c/Techtter

Spring Boot & Cassandra CRUD API Example

Spring Boot and Cassandra NoSQL DB can be dockerized can be run as microservices using docker compose. In the following video you will learn how to integrate or connect Spring Boot Application with Cassandra data base. And you will learn how to build REST API using Spring Boot framework. Finally we test the Spring Boot application whether it can connect with Cassandra or not by testing with Postman tool.

To get to know complete details how to run both Spring Boot and Cassandra using Docker Compose, check the following video.

How To Containerize or Dockerize Spring Boot Application Without Dockerfile?

Do you know we can Dockerize Spring Boot Application without Dockerfile? Yes we can do that from Spring Boot 2.3 version. Spring Boot 2.3 added with natively support of cloud-native buildpacks. So that we no need to have Dockerfile in our project base directory. To know complete details how we can dockerize Spring Boot, just watch the following video:

Exploratory Data Analysis & Data Preparation in Machine Learning or Data Science

Exploratory Data Analysis or Data Exploration is another process that is critical in machine learning pipeline. Since it makes you understand what kind of data you have and what is data format. And also by exploring the data you will know how that data is useful to take business decisions. It may contain very raw data and it may null values. By exploring the you can get complete knowledge of your data and you can know how pre process it by eliminating null values and duplicates in the data.

To get to know more about how you can explore the data, just check the following video. If you like the video like it and subscribe to channel @ https://www.youtube.com/c/Techtter

Data Collection & Connectivity in ML Pipeline

Data Collection and Data Conenctivity are important processes in ML Pipeline. You should know how to connect and collect the data from the data sources. The data source located in on-premises or remote locations. Irrespective of data locality you should be able to connect the data source and collect the data and should store the data in centalized location.

How To Build Data Pipeline on AWS?

Which tool?? Glue or Lambda function ??  Kinesis or Kafka??, Redshift or  Redshift Spectrum?? Quicksight for visualization?? Which AWS service is better?

Building data pipeline on AWS triggers few questions for the new users of AWS cloud. Even I too had a similar feel when I started working on my project sometime back. Just I wasnt to share that knowledge 
how to design and implement. There are number of tools or services on AWS, but what is the right tool.

I have demonstrated my experience while building data pipeline on AWS in the following video. Please watch the video and let me know your thoughts in comments section.

What is Helm in Kubernetes? How to Write Helm Charts for Deployment? [DevOps]

what is helm, helm charts, kubernetes

Helm is like a package manager for Kubernetes like "yum for centOS" "or apt-get for UbuntuOS". Helm Charts simplifies the way of deploying applications(docker images) on Kubernetes cluster on DTAP environments. Helm contains an important component in called Tiller which provides a way to manage releases on K8s cluster. In this video, you will learn about What is Helm? and How Helm works under the hood to deploy applications in Kubernetes Cluster. How to use & when to use Helm and also we discuss helm features Helm Charts, Templating Engine & Release Management with Tiller in Helm. Subscribe to me on Youtube: https://bit.ly/2LrKSK2

Watch the video to know more about Helm and Helm Charts and why Tiller is removed from Helm version 3.

How To Create Kubernetes EKS Cluster on AWS using Terraform? [DevOps]

Terraform simplifies the provisioning infrastructure as code on different cloud environments. The following video explains how to write terraform script to deploy EKS Kubernetes cluster AWS cloud. And also you will learn how to deploy Cluster Autoscaler (CA) and Horizontal Pod Autoscaler(HPA). After deployment of the both, you will learn deploying simple php application and we will test autoscaling of application pods and based on cpu usage and user requests. And also we experiment with how to auto scale out nodes as well based on resources availability.
