Top Stories by John Wetherill

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 discussions with architects and developers at a handful of organizations who are moving forward with microservices, as well as from my experience building a couple microservices-based systems before microservices was a thing. Words to the Wise / Words to the Weary Start small, move fast Don't e... (more)

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)

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...

The Slope of Enlightenment By @bcferrycoder | @DevOpsSummit #DevOps #Microservices

Docker's Birthday and Welcome to the Slope of Enlightenment It's 2:15 pm on a Friday, and I'm sitting in the keynote hall at PyCon 2013 fidgeting through a succession of lightning talks that have very little relevance to my life. Topics like "Python code coverage techniques" (ho-hum) and "Controlling Christmas lights with Python" (yawn - I wonder if there's anything new on Hacker News)...when Solomon Hykes takes the stage, unveils Docker, and the world shifts. If you haven't seen it yet, you should watch the video of Solomon's Pycon The Future of Linux Containers talk that spurre... (more)
