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 virtualization and the recent rampant frenzy over containerization, keeping on top of cloud-specific security vulnerabilities is a huge effort. Here we'll look at a handful of high-level cloud security concerns that keep security folks up at night. 1. Transparency is crucial. Transparency is hi... (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)

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)

Virtualization, an Implementation Detail By @bcferrycoder | @CloudExpo #DevOps #Microservices

In the Cloud, Virtualization Is an Implementation Detail Virtualization is everywhere. Enormous and highly profitable companies have been built on nothing but virtualization. And nowhere has virtualization made more of an impact than in Cloud Computing, the rampant and unprecedented adoption of which has been the direct result of the wide availability of virtualization software and techniques that enabled it. But does the cloud actually require virtualization? I think not. What Makes Cloud Computing Cloud Computing? According to NIST Cloud Computing has a handful of defining chara... (more)

PaaS and #Microservices Part 3 By @bcferrycoder | @ DevOpsSummit #DevOps #PaaS

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, or... (more)
