When designing Workiva’s durable messaging system we took a hard look at using Amazon’s Kinesis as the message storage and delivery mechanism.

Architecture is the bridge between (often abstract) business goals and the final (concrete) resulting system. – Software Architecture in Practice A software architect should act as a bridge between business stakeholders and technical stakeholders.

I write Markdown using Vim and the vim-pencil plugin and one of the things that particularly bothered me was that, by default, iTerm2 and the solarized colour scheme did not support italic text.

I’ve been asked recently, what’s the difference between Swagger and Thrift (or gRPC)?

Better a diamond with a flaw than a pebble without.

Here it is.

Having created a custom Boomi connector, the next step is packaging it as a Jar file for testing and release.

This article will show you how to create a custom connector for reading data from Dell Boomi.

Business intelligence and analytics use cases involve complex queries on potentially very large databases.

This tutorial describes how to setup a test integration running Dell Boomi.

In a REST application, it’s often the case that several clients might interact with a single resource, each holding a copy of the resources state.

Amazon’s API Gateway provides the ability to transform a response from an endpoint into a different format for return to the client.

The web supports a global network of billions of devices and users, and a key component of this support is effectively caching frequently accessed data along the request-response path.

As part of testing our Amazon API Gateway deployment, we set up JUnit tests to run automated Swagger/OpenAPI validation using Swagger Request Validator and REST-assured.

The decision to build products using a service-oriented (or microservice) architecture has enormous technical and organizational impact that is reflected in everything from how teams write code, to how they communicate, to how the organization itself is s…

Amazon’s API Gateway provides the facilities to map an incoming request’s payload to match the required format of an integration backend.

In our previous article on Swagger, we defined a Player API modelling GET access to a Player resource.

Full sample code for this article is available on Github.

The goal of Swagger is to define a standard interface for describing REST APIs.

As someone who is being recently re-introduced to the Java platform, there are a lot of components and pieces to become familiar with.

Amazon Simple Queue Service (SQS) is a message queue service that allows applications to reliably queue messages from one system component to be consumed by another component.

When integrating two independent services you have two options: making a remote procedure call (RPC), or sending a message.

A big portion of any software engineering revolves around integrating multiple, disparate applications into a cohesive and functional whole.

The request was fairly simple — iterate through some data and update some dates.

Point-to-point communication between servers usually works just fine when one or two instances are communicating.

After reading the Thrift whitepaper and sending your first message, you may still have some questions about how Thrift actually works.

I recently finished reading the excellent book “Release It!”

Metrics-Driven Development is an emerging term developing from the practices of continuous integration, continuous delivery, dev ops, and agile software methodologies.

Testing concurrent objects can be challenging.
