Developing Microservices for PaaS with Spring and Cloud Foundry

Marc Andressen has famously said "Software is eating the world." What does that mean? We take it to mean that multiple industries with historically entrenched leaders are being disrupted by businesses built around a software core. These software factories are characterized by: tight feedback loops rapid iteration horizontal scaling mobile-first UX continuous delivery. These factors have contributed to drive a change in how we approach infrastructure, which has taken the lead in adapting to meet these needs with the move to the cloud, and Platform as a Service (PaaS) offerings like Cloud Foundry have raised the level of abstraction to a focus on an ecosystem of applications and services.

SpringOne2GX 2014 Replay: Develop powerful Big Data Applications easily with Spring XD

Recorded at SpringOne2GX 2014. Speakers: Mark Fisher and Mark Pollack Slides: http://www.slideshare.net/SpringCentral/develop-powerful-big-data-applications-easily-with-springxd Big Data Track Spring XD aims to provide a one stop shop for writing and deploying Big Data Applications. It provides a scalable, fault tolerant, distributed runtime for Data Ingestion, Analytics, and Workflow Orchestration using a single programming, configuration and extensibility model. By not requiring developers to rationalize all of this themselves across the many different solutions available today, Spring XD greatly reduces the inherent complexity of Big Data development. It's all built on proven projects like Spring Integration, and Spring Batch. You'll see for yourself how this heritage combines to provide a scalable runtime environment, that is easily configured and assembled via a simple DSL.

A rebuttal against terrible interview advice

Agile teams deliver continuously

Agile teams deliver continuously. Which means, Code must be integrated continuously and Code must be tested continuously. Teams that follow this recipe will have an improved chance of producing quality code continuously. Product Owners will be happy about the increased team velocity. Developers will be happy about the confidence to make changes. Business will be happy about the increased quality of the product.

Static Typing Is Not for Type Checking

In his post “Strong typing vs strong testing” Bruce Eckel described the idea that statically (or strongly) typed languages don’t give you much, because you should verify your programs with tests anyway. While this looks like a very good point initially, I have some objections.

On Setting Your Initial WIP Limits

During a recent training course, I was asked how their team should calculate the initial WIP limits for a team starting out with Kanban. Now, the correct answer is that you need to experiment; find the WIP limit that is low enough to identify bottlenecks & promote a smooth flow, but is still high enough not to artificially create bottlenecks. This answer is all well & good to refine the limits, but doesn't help you when starting.

To code or not to code

Choosing to write custom code to solve a problem can give you a lot of flexibility in the end product, but ultimately will end up causing a lot of money and time for development and ongoing support. In some cases, it makes more sense to try to abstract the development process as much as possible, minimizing the amount of code to be written. In this article we will look at a number of ways to approach building an application on top of existing data, and why you might choose one over the other.
