Distributed microservices architecture: Istio, managed API gateways and, enterprise integration

The rise of microservices architectures drastically changed the software development landscape. In the past few years, we have seen a shift from centralized monoliths to distributed computing that benefits from cloud infrastructure. With distributed deployments, the adoption of microservices, and system scaling to cloud levels, new problems emerged, as well as new components that tried to solve the problems.

By now, you most likely have heard that the service mesh or Istio is here to save the day. However, you might be wondering how it fits with your current enterprise integration investments and API management initiatives. That is what I discuss in this article.

Full API lifecycle management: A primer

APIs are the cornerstone of so many recent breakthroughs: from mobile applications, to the Internet of Things, to cloud computing. All those technologies expose, consume, and are built on APIs. And those APIs are a key driver for generating new revenue. Salesforce generates 50% of its revenue through APIs, Expedia generates 90% of its, and eBay generates 60% of its. With APIs becoming so central, it becomes essential to deal with full API lifecycle management. The success of your digital transformation project depends on it!

This article describes a set of full API lifecycle management activities that can guide you from an idea to the realization, from the inception of an API program up to management at scale throughout your whole company.

Effortless API creation with full API lifecycle using Red Hat Integration (Part 1)

Nowadays, API development with proper lifecycle management often takes days if not weeks to get a simple API service up and running. One of the main reasons behind this is there are always way too many parties involved in the process. Plus there are hours of development and configuration.

First, the system analysts negotiate the API interface with the API consumer; then the developer writes the actual API to implement the interface. They then pass the API on to the DevOps team that is in charge of deploying the API. And it is not done yet; then the deployment info needs to be passed to the operations team that is in charge of setting up the API endpoints in the management system and also applying the access policies.

The speed of providing managed API services can be one of the major factors in the success of a company’s business.

This article, which is the first in a series of three articles, describes how the new Red Hat Integration bundle allows citizen integrators to quickly provide an API through tools that make creating an API in five simple steps effortless.

Integrating third-party identity providers with Red Hat 3scale API Management

This post describes how to configure OpenID Connect (OIDC) authentication using an external Identity Provider (IdP). With the new release of Red Hat 3scale API Management, version 2.3, it is possible to use any OIDC-compliant IdP during the API authentication phase. This is a very important new feature because it makes it possible to integrate any IdP already present in your environment—without having to use an Identity Broker—thus reducing overall complexity.

Adding API Gateway Policies Now Easier With Red Hat 3scale API Management

With the June 2018 release of Red Hat 3scale API Management 2.2, adding API Gateway policies to your API management layer is easier than ever.

What is a Policy?

Red Hat 3scale API Management provides units of functionality that modify the behavior of the API Gateway without the need to implement code. These management components are know in 3scale as policies. The configuration for the bundled policies is available from the API Manager Portal, where you can define the behavior of your API integration.

The order in which the policies are executed, known as the “policy chain”, can be configured to introduce differing behavior based on the position of the policy in the chain. Adding custom headers, perform URL rewriting, enable CORS, and configurable caching are some of the most common API gateway capabilities implemented as policies.

An API Journey: From Idea to Deployment the Agile Way–Part III

This is part III of a three-part series describing a proposed approach for an agile API lifecycle: from ideation to production deployment. If you missed it or need a refresher, please take some time to read part I and part II.

This series is coauthored with Nicolas Massé, also a Red Hatter, and it is based on our own real-life experiences from our work with the Red Hat customers we’ve met.

In part II, we discovered how ACME Inc. is taking an agile API journey for its new Beer Catalog API deployment. ACME set up modern techniques for continuously testing its API implementation within the continuous integration/continuous delivery (CI/CD) pipeline. Let’s go now to securing the exposition.

Red Hat Summit 2018: Speakers on the forefront of Cloud-Native application development

May 8th – 10th at Red Hat Summit 2018 in San Francisco, you’ll get to see, hear, and meet speakers who are working on the forefront of cloud-native application development. Some are core developers working on Red Hat products or in the upstream open source communities. A number of speakers have published books on topics such as microservices and integration.  Others are working directly with developers at Red Hat customer sites helping those organizations efficiently move to cloud-native application development.   The speakers include:

An API Journey: From Idea to Deployment the Agile Way–Part I

The goal of this series of posts is to describe a proposed approach for an agile API delivery process. It will cover not only the development part but also the design, the tests, the delivery, and the management in production. You will learn how to use mocking to speed up development and break dependencies, use the contract-first approach for defining tests that will harden your implementation, protect the exposed API through a management gateway and, finally, secure deliveries using a CI/CD pipeline.

I coauthored this series with Nicolas Massé, who is also a Red Hatter. This series is based on our own real-life experience from our work with the Red Hat customers we’ve met, as well as from my previous position as SOA architect at a large insurance company. This series is a translation of a typical use case we run during workshops or events such as APIdays.
