Cloud Computing and Precision Time Protocol (PTP)

When it comes to expanding cloud computing – timing is everything

If cloud computing is going to spread to more mission-critical type applications, it needs to get more accurate when it comes to transaction-based applications. Trying to keep everything in a structured framework is going to require a more rigorous network infrastructure that includes timing down to milliseconds, if not nanoseconds.

One way to accomplish this is to use the IEEE 1588 protocol or "Precision Time Protocol" (PTP), which provides timing. In an earlier article entitled, "Cloud Transaction Synchronicity," I discussed the need for this type of capability if financial organizations are to look at cloud computing as a real solution for any transactions-based services.

When It Comes to Mission Critical, Timing Is Everything
Few talk about this essential need because few understand what makes "the cloud" work. Any vendor or system architect always draws "the Cloud" in sales presentations and executive overviews, but how many can draw and discuss the detailed network infrastructure that supports it? A lot goes on inside that obscure cloud drawing.

It's like twisting the old adage of "Don't tell me how to build a watch when all I ask is what time it is?" When it comes to cloud computing, many can draw you the cloud, but a rare few can diagram how packet traffic and timing in the network is implemented and applied.

In many mission-critical applications, timing cannot be left as an afterthought or as a function that is provided by several servers. Accuracy is key, and that means taking timing off of a single master clock.

Just like the Public Switched Telephone Network (PSTN) that takes its timing off of one clock, any mission-critical application that needs accuracy must have timing off of one source if it's going to be provided in some type of "cloud" environment.

Bear in mind, this additional capability is going to increase the cost of the cloud computing environment.

The Three Rs of Mission-Critical Cloud Applications
Supporting the Three Rs of mission-critical cloud applications (Reliability, Redundancy, and Resiliency) means a higher price for equipment and services as well as the skill levels of personnel who support this application. As more of an enterprise's electronic commerce is implemented and relied upon as a primary revenue stream, the equipment and network services supporting that endeavor will take up a bigger cut of the budget.

It wasn't too long ago that many organizations were slashing their IT budgets. Not really a good strategy in the long term. This showed the short-sightedness of many senior executives who were more worried about their year-end bonus, instead of setting a course for the organization to sustain a competitive advantage.

You have to spend money to make money and that's true when it comes to applying technology to the enterprise.

Just like any quality methodology, adding technology to remain competitive is an ongoing process, not a one-shot deal. If mission-critical applications are going to be part of sustaining a competitive advantage, you need to have the support of executive management as well as a solid budget.

When it comes to implementing mission-critical applications, "Timing as a Service" (TaaS©) needs to be perfected in the cloud computing market.

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
Data is the fuel that drives the machine learning algorithmic engines and ultimately provides the business value. In his session at Cloud Expo, Ed Featherston, a director and senior enterprise architect at Collaborative Consulting, discussed the key considerations around quality, volume, timeliness, and pedigree that must be dealt with in order to properly fuel that engine.
All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of Soli...
Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
SYS-CON Events announced today that Dataloop.IO, an innovator in cloud IT-monitoring whose products help organizations save time and money, has been named “Bronze Sponsor” of SYS-CON's 20th International Cloud Expo®, which will take place on June 6-8, 2017, at the Javits Center in New York City, NY. Dataloop.IO is an emerging software company on the cutting edge of major IT-infrastructure trends including cloud computing and microservices.

Join Impiger for their featured webinar: ‘Cloud Computing: A Roadmap to Modern Software Delivery’ on November 10, 2016, at 12:00 pm CST. Very few companies have not experienced some impact to their IT delivery due to the evolution of cloud computing. This webinar is not about deciding whether you should entertain moving some or all of your IT to the cloud, but rather, a detailed look under the hood to help IT professionals understand how cloud adoption has evolved and what trends will impact th...
In his session at 19th Cloud Expo, Claude Remillard, Principal Program Manager in Developer Division at Microsoft, contrasted how his team used config as code and immutable patterns for continuous delivery of microservices and apps to the cloud.

President Obama recently announced the launch of a new national awareness campaign to "encourage more Americans to move beyond passwords – adding an extra layer of security like a fingerprint or codes sent to your cellphone." The shift from single passwords to multi-factor authentication couldn’t be timelier or more strategic. This session will focus on why passwords alone are no longer effective, and why the time to act is now. In his session at 19th Cloud Expo, Chris Webber, security strateg...
The many IoT deployments around the world are busy integrating smart devices and sensors into their enterprise IT infrastructures. Yet all of this technology – and there are an amazing number of choices – is of no use without the software to gather, communicate, and analyze the new data flows. Without software, there is no IT. In this power panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, Dave McCarthy, Director of Products at Bsquare Corporation; Alan Williamson, Principal...
