Use Enterprise Java for Microservices : MicroProfile

Eclipse MicroProfile or in other words, "Optimized Enterprise Java for a Microservices Architecture" is a way to eliminates the risk of vendor lock-in and maintains the developers’ freedom of choice when implementing Microservices. Microservices is the most popular architecture when creating cloud-native applications. I have written another article which introduces microservices. https://www.harshajayamanna.com/2019/01/introduction-to-microservices_30.html Eclipse MicroProfile is an open-source community specification for Enterprise Java microservices. It is a project under Eclipse foundation and backed by individuals, organizations, vendors. Microprofile Community I have highlighted the word "specification" in the previous paragraph. That means Microprofile is a specification which can be implemented by anybody and that eliminates the risk of vendor lock-in. Some of the specifications which developers are already familiar with are Java EE 8 Speci

MQTT, HTTP, or WebSockets for IoT Communication

MQTT (MQ Telemetry Transport) Protocol It is a publish/subscribe, extremely simple and lightweight messaging protocol. Why do we use MQTT? MQTT is designed for constrained devices that use low-bandwidth, high-latency networks. Let's look at one of the case studies from AWS IoT. Taiwan-based Weintek designs and manufactures human-machine interface (HMI) products. Before using AWS, HMIs were not connected to networks and they had to transfer and upload data manually to the network. Later, they decide to implement AWS infrastructure and use IoT Technology. Since MQTT is lightweight, it enabled them to collect data from thousands of machines using relatively little bandwidth MQTT pub/sub pattern Pub/sub pattern MQTT uses the pub/sub pattern to connect relevant parties. This protocol enables an application to announce events to multiple interested consumers asynchronously, without coupling the senders to the receivers. In this pattern, the publisher sends
