Enterprise Integration for Beginners

  Just released! It is a great and humble feeling to release my very first book “Designing Microservices Platforms with NATS” on 19th November 2021 (first edition). Cover Image of Designing Microservices Platforms with NATS You can read it through  Amazon ,  Barnes and Nobel ,  Packt , and other distributors worldwide. Why another microservices book? I hear you! Why there are so many books about microservices? Is that so complicated? Why do people use it? Those were some of the questions I had when reading about microservices in the wild (internet). The more I read through, the more I realized that there is something missing.  That missing piece was the first principle and the simplicity when building microservices. That is why I thought of writing a book on microservices that people can understand and start building applications with microservices without falling into the trap of ultra complexity. This book focuses on building applications first and includes al...

Enterprises software systems are becoming more and more distributed and the number of on-premise and cloud applications used within the enterprise is in rise. It is essential to have a modern approach to build integrations with these systems, applications and data to provide highest value to the customers and take your business to the next level. In this article, I'm discussing on building a modern integration platform with WSO2 technology stack and other open source software. https://medium.com/swlh/building-a-modern-brown-field-enterprise-system-with-wso2-technology-f25a66aaf376

WSO2 recently announced the latest version of it’s API Gateway which is API Microgateway 3.0. This release comes with a cloud-native, enterprise-grade, open-source API gateway along with full API lifecycle management capabilities. You can find more details about the WSO2 API Microgateway by referring the link below. https://wso2.com/api-management/api-microgateway/ With this new microgateway, WSO2 allows enterprises to deploy API gateway with a whole new set of deployment patterns. In this article, I will be talking about a few possible deployment patterns with WSO2 API Microgateway. Though this article is focused on WSO2 API Microgateway, some patterns can be used independent of the same. Here is the link to the original medium post. https://medium.com/@chanakaudaya/wso2-api-microgateway-deployment-patterns-8cb8f25a7619

Microservices architecture is not a silver bullet for all your enterprise IT system requirements. Some requirements come just after implementing a microservices architecture. Service Mesh and API Management are such mechanisms which works along with microservices to build a comprehensive microservices architecture. The below post explains how these 3 pillars can help you to build an effective microservices platform. https://medium.com/microservices-learning/microservices-service-mesh-and-api-management-7408c001fb31

Microservices architectures are becoming more and complex and challenging to maintain. Given the advantages it brings to the enterprise IT ecosystem, the complexity is out-numberes by the advantages. Service Mesh allows the enterprises to control communication amongst microservices as well as communications from external clients to the microservices. Istio is becoming more and more popular as a service mesh because it provides both data plane and control plane capabilities of a service mesh. The following medium post explains the Istio Service Mesh along with its usage. https://medium.com/microservices-learning/istio-service-mesh-pattern-61a2848704bf

Enterprise Application Integration (EAI) is a complex problem to solve and different software vendors have produced different types of software products like ESB, Application Server, Message Broker, API Gateways, Load Balancers, Proxy Servers and many other forms. These products have evolved from a monolithic, heavyweight, high-performing runtimes to lean, modularized, micro-runtimes. Microservices Architecture (MSA) is having a major impact on the way architects design their enterprise software systems. The requirements which were there 10 years ago has been drastically changed due to modern advancements of MSA, Containers, DevOps, Agility and mainly due to crazy customer demands.    The below post discusses the requirements which needs to be fulfilled by modern enterprise application integration projects.    https://medium.com/@chanakaudaya/understanding-the-modern-enterprise-integration-requirements-4ae58913a59d    

WSO2 API Manager is one of the leading open source API management platforms available in the market. According to a recent Gartner research (2018) it has been identified as the best “visionary” type vendor in the market. It comes with a support for full API lifecycle management, horizontal and vertical scalability and deployment options of on-premise, public cloud (SaaS) and managed (private) cloud. In this article, I’m going to discuss about how you can implement a service mashup (or service orchestration) with WSO2 API Manager within 10 minutes. Let’s get started by downloading the WSO2 API Manager from the following link. https://wso2.com/api-management/install/ Once you downloaded the product, you can install it to the desired location. Let’s consider the directory which WSO2 API Manager is installed as “APIM_HOME”. You can start the product using the following command within the APIM_HOME directory. $ sh bin/wso2server.sh Before implementing the use case, let’s understand the sce...

Microservices Architecture (MSA) is becoming the SOA of the modern era. Like the way SOA improved the enterprise software architecture with new patterns and architectures around that, Microservices Architecture (MSA) has tripped off several new architectural styles and new concepts around how people build enterprise software. Some of them are - Service Mesh — Technique to communicate amongst microservices - Serverless — Running your code as functions on cloud - Micro Integration — Run your integrations as microservices - Micro Gateway — Run your api gateways in a microservices compatible manner All these architectures can be categorized under the common umbrella of “microservices” and can be called as “micro-architecture”. In this post, I’m going to introduce the micro-architecture and how Micro API Gateway can be utilized in such an architecture.                                   Figure...

Microservices hype is not over yet. There are technologies like serverless computing and multi cloud platforms coming up and they will eventually increase the need for microservices style programming and application development. When it comes to enterprise software development, we can see that it is a mixture of traditional soa style systems, api driven systems which are backed my microservices or above mentioned soa systems, cloud based SaaS applications as well as proprietary software systems running on premise. Enterprise is going to be like this for a foreseeable future. It is quite important that as an architect or a senior leader who is responsible for an enterprise software architecture to understand the proper approach to built your software eco system which will be an ever important factor to your business. When it comes to building such a complex system, there are 3 main approaches stands out Polyglot programming model Platform based programming model (open source) Ven...
