Auto-Publishing & Monitoring APIs With Spring Boot

If you are heading down the path of a Microservices style of architecture, one tenant you will need to embrace is automation. Many moving parts are introduced with this style of architecture. If successful, your environment will have a plethora of service APIs available that the enterprise can consume for application development and integration.

This means that there must be a way that available API documentation can be discovered. API information needs to be effectively communicated throughout the enterprise that shows where APIs are used, how often APIs are used, and when APIs change. Not having this type of monitoring in place will hinder and possibly cripple the agility benefits that a Microservice style of architecture can bring to the enterprise.

This blog will describe how Swagger/OpenAPI documentation can be applied to aย Spring Boot implementation. We will show how API documentation and monitoring can be automatically published toย an API documentation portal.

As an example, we introduce a reference Spring Boot API CRUD application (using Spring MVC/Data with Spring Fox) and set up the automatic publishing of API documentation and statistics to documentation portal GrokOla. In the example, we introduce two open source utilitiesย to help and allow published APIs the ability toย be searched and notify users whenย changed….

White Paper Published – Microservices: Patterns for Enterprise Agility and Scalability

Keyhole Software Architecture, Articles, Company News, Microservices, Tutorial 4 Comments

We’re excited to announce the release of a new, free white paper on the Microservices software architecture style.

Microservices is an architectural pattern gaining steam in the development community. A Microservices architecture addresses problems that modern enterprises often face, including responding to market demands, handling spikes in traffic, and being tolerant to failure. These benefits are achieved by functionally decomposing a businessโ€™ domain into microservices, services that handle only a single responsibility.

In this white paper, we discuss how Microservices came to be, contrasting architecture patterns, features of a Microservices architecture, established patterns, how to get started with Microservices, and suggestions for Microservices adoption.

Security in the Microservices Paradigm

Zach Gardner Architecture, Articles, Microservices Leave a Comment

One of the least glamorous aspects of implementing a Microservices architecture is the security. It’s not fun or cool when compared to things like the circuit breaker or service discovery, yet it is a critical piece of the ecosystem especially in an enterprise setting.

I’m working on a large Microservices project for a healthcare enterprise on the East Coast. One of the first pieces of the infrastructure we assisted with was security, which has turned out to be a lifesaver for everything that has come after it. I was able to see what security works well as well as what does not work so well in a Microservices environment. In this blog post, I will share a medium to high-level look into how security can be implemented in Microservices.

Taking A Mixed Approach To Single-Page Applications

Chris Berry Angular, Articles, Development Technologies & Tools, JavaScript, Single-Page Application Leave a Comment

A coworker came to me with a problem. The client he was working with would be building hundreds of single-page applications and all would need to be tied into a single shell application. He had first attempted to use an iFrame contained within another single-page application to display the child applications.

While this worked, he came up against another requirement: the child applications may or may not need access to data from the parent shell application.

It was at this point he came to me for suggestions. I had been playing with this exact idea for sometime; how can you manage a collection of Single-Page Applications and still share data between them?

At this point, I decided to create a hybrid solution of mixing Single-Page Applications with a server-rendered shell application. The following is the process I took for creating this solution, highlighting some of the pain points with some suggestions for further enhancements.

Cobol to Java

Adventures In Modernization: Strategy + Example Converting COBOL To Java

We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy
