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?

The emergence of containerization in microservices technology has given rise

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.

Methods in Implementation class invoke a Business service

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.

if you have any suggestions or ideas for learning resources for one or more of the following subjects, generally or in relationship to InterSystems products, I would be ver

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

- thereafter use a set of CRU

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 follows
1. Service 
a. Read a csv file, loop through all records
b. In each loop make one json msg and add it to the json array of messages
The message structure is

Hi everyone,

are you curious which topics we are going to cover at this year’s Global Summit? You have come to the right place! I will provide you with a sneak peek of what you can expect from the areas I am responsible for.

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:

In a nutshell, they are all about breaking down, into separate self-contained units, the processes and functionality that y

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: 

  https://github.com/robtweed/qewd/blob/master/example/jwt

In my earlier post on JSON Web Tokens (JWTs) and QEWD I used this example application to explain how to use JWTs.  This example application also demonstrates how to set up a simple Micro-Service, in this case a service that handles user authentication.  So let me now delve into that aspect

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.

Background

First of all I must confess. Early this summer our Czech colleague Daniel Kutac was asking me to collect some information about a health care product developed in Hungary. When I got the feedback from the related company, it turned out, that the product is a modular system, based on MicroServices Architecture (MSA). O
