Cloud and Things and Big Operational Data Software-defined architectures are critical for achieving the right mix of efficiency and scale needed to meet the challenges that will come with the Internet of Things If you've been living under a rock (or rack in the data center) you might not have noticed the explosive growth of technologies and architectures designed to address emerging challenges with scaling data centers. Whether considering the operational aspects (devops) or technical components (SDN, SDDC, Cloud), software-defined architectures are the future enabler of business, fueled by the increasing demand for applications. The Internet of Things is only going to make that even more challenging as businesses turn to new business models and services fueled by a converging digital-physical world. Applications, whether focused on licensing, provisioning, managin... (more)

Just What Does 'Operationalize' Mean Anyway?

Just What Does 'Operationalize' Mean Anyway? Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like that of accelerating time to market for all important applications. But what does it really mean to operationalize the network, or app deployments, or really, anything? Operationalization is a lot like DevOps in that it's more of an approach to how you ... (more)

DevOps & Cloud's Predictable Provisioning Problem | @DevOpsSummit [#DevOps]

What DevOps Can Do About Cloud's Predictable Provisioning Problem Go ahead. Name a cloud environment that doesn't include load balancing as the key enabler of elastic scalability. I've got coffee... so it's good, take your time... Exactly. Load balancing - whether implemented as traditional high availability pairs or clustering - provides the means by which applications (and infrastructure, in many cases) scale horizontally. It is load balancing that is at the heart of elastic scalability models, and that provides a means to ensure availability and even improve performance of app... (more)

DevOps & SDN | @DevOpsSummit [#DevOps]

Kirk Byers at SDN Central writes frequently on the topic of DevOps as it relates (and applies) to the network and recently introduced a list of seven DevOps principles that are applicable in an article entitled, "DevOps and the Chaos Monkey. " On this list is the notion of reducing variation. This caught my eye because reducing variation is a key goal of Six Sigma and in fact its entire formula is based on measuring the impact of variation in results. The thought is that by measuring deviation from a desired outcome, you can immediately recognize whether changes to a process impro... (more)

Shellshock: Keep Calm and Mitigate | @DevOpsSummit [#DevOps]

Shellshock, appropriately and of course punnily named, is ravaging the Internet right now. Active exploits continue to grow in number and in complexity. While there are multiple avenues through which this vulnerability can be exploited, the most active one at the moment appears to be via vulnerable Internet-facing systems running web applications. Register For DevOps Summit FREE (before Friday) ▸ Here These attacks take advantage of the lax constraints on HTTP headers that allow strings of nearly limitless length to be passed not just to the web server, but on to the system via ...
