Top Stories by John Wetherill

This is part of the ever-expanding "Microservices and PaaS" blog series covering the rapidly evolving use of microservices in modern cloud software projects. Parts I and II introduced microservices concepts and discussed patterns and practices being spearheaded by microservices pioneers, notably Netflix, who were represented at a recent microservices meetup that was the genesis of this series. Part III presented a list of challenges and pitfalls that adopters of microservices face. This list is formidable and somewhat daunting; pointing out the significant changes in mindset, organizational structure, and overall development practices needing to take place prior to plunging into microservices. Fortunately, tooling and other supporting technologies are evolving almost as fast as the microservices practices are themselves. Platform-as-a-Service (PaaS) is at the fore... (more)

PaaS and #Microservices By @bcferrycoder | @DevOpsSummit #DevOps #PaaS

In the first four parts of this series I presented an introduction to microservices along with a handful of emerging microservices patterns, and a discussion of some of the downsides and challenges to using microservices. The most recent installment of this series looked at ten ways that PaaS facilitates microservices development and adoption. In this post I'll cover some words of wisdom, advice intended for individuals, teams, and organizations considering a move to microservices. I've gleaned this advice from the various articles and meetups mentioned above, from dozens of dis... (more)

Locking Down the Cloud By @bcferrycoder | @DevOpsSummit #DevOps #Microservices

CIOs are increasingly concerned about cloud security. And they should be. With the recent outbreak of visible breaches at high-profile organizations like Target, Anthem, and others, and the subsequent damage they cause, corporations are scrambling to make sure their cloud applications, whether on private, public, or hybrid clouds, are safe. But cloud security is complex. With ephemeral applications and services springing up around multiple data centers, with dozens or hundreds of independent microservices each with their own access mechanisms, with the widespread adoption of vir...

PaaS and #Microservices: Part 6 By @bcferrycoder | @DevOpsSummit #DevOps #PaaS

This is the final installment of the six-part series Microservices and PaaS. It seems like forever since I attended Adrian Cockroft's meetup focusing on microservices. It's actually only been a couple of months, but much has happened since then: countless articles, meetups, and conference sessions focusing on microservices have been delivered, many meetings and design efforts at companies moving towards a microservices-based approach have been endured, and five installments of this blog series have been written. There's no doubt that microservices, like containerization and DevOps... (more)

Bringing Shadow IT into the Light By @bcferrycoder | @CloudExpo #Cloud

Going Rogue with PaaS: Bringing Shadow IT into the Light In a recent blog I suggested that it's okay to install PaaS on a couple of PCs, and run them "under the desk" for cloud development. This immediately provoked a comment from a reader who said "You're not endorsing Shadow IT are you?" Well in fact I am. By the end of this blog you will too. What Is Shadow IT? Shadow IT, aka Rogue IT, has a bad rep. And it probably should. It can compromise security, increase IT costs, result in dangerous leakage of data and IP, and get people fired. It also generates friction and thus expands... (more)
