What is Kubernetes?

Kubernetes is an open-source container orchestration framework developed by Google. In essence, it controls container speed and helps you manage applications consisting of multiple containers. Additionally, it allows you to operate them in different environments, e.g., physical machines, virtual machines, Cloud environments, or even hybrid deployment environments.

What problems does it solve?

Hello Everyone,

We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager. 

Our aim is to implement a Microservices Architechture where Services are small in size,  bounded by contexts, autonomously developed, and independently deployable. 

We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.

greetings Community!

InterSystems Learning Services is working to identify and create libraries of high-quality learning resources for third-party technologies, platforms, and systems that are part of, integrated with, or commonly used with InterSystems products and technologies. we don't create content for these ourselves, but want to support our clients, external and internal, in learning about them and how to use them.

I've created a new repository that I will use for providing examples of various scenarios and use cases for QEWD

https://github.com/robtweed/qewd-microservices-examples

Initially it contains a example of a scenario I'm often asked about: a set of REST APIs, with JWT support, implemented as a set of QEWD MicroServices, each of which uses Cache or IRIS running on a Windows system.

What I've provided is a detailed, step-by-step guide (with detailed explanations) of how to set up such a system.

The example shows a use case of REST APIs to:

- authenticate / login

Hello,Fellow community members, here is an extendable / re-usable / generic pub-sub model.An initial calling service reads a CSV file, parses through all records and transforms it to a generic JSON message.The message is then transported via a pub-sub business process to the end-points Targets (business operations)as configured for the subscribers for each Topic as demonstrated in the image below.Steps and flow to implement this are as follows1. Service a. Read a csv file, loop through all recordsb. In each loop make one json msg and add it to the json array of messagesThe message structure is

In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD.  In this post I'll give some background to how they work and the thinking behind them.

If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search.  Here's a good starting point:

If you read my previous post that introduced QEWD Micro-Services, you're hopefully eager to learn how to use them.  So in this post I'll explain what you need to know in order to get started.

If you look in the QEWD repository, you'll find the folder:

I've written previous IDC articles about QEWD and how it provides a very high-performance, yet simple-to-use, way of integrating Node.js with Cache 

A beginner’s guide to position Ensemble in regards to MicroServices Architecture (MSA). MSA is getting more visibility in the Enterprise Java world therefore it is vital to understand what is behind the buzz. I make a (humble) attempt to write my view and share with you.
