I seem to keep coming back to the same question when discussing Cloud Computing. Can cloud computing be treated as a commodity that could be brokered and or exchanged? Recently a few have attempted to do this, notably a German firm called Zimory.
To give you a little background, before the development of the Enomaly ECP platform. I had the grand idea to create what I described as "Distributed Exchange (DX)" (circa 2004 - I've put the site online temporarily for demo purposes). This was actually one of the original motivations for the creation of the original ECP platform (aka Enomalism) The idea of DX was to create a platform and marketplace which would allow companies to buy and sell excess computing capacity similar to that of a commodities /exchange marketplace. Think Google Adwords & Adsense for compute capacity.
I actually put quite a bit of thought into the whole concept. Generally the concept was to use a commodity-based approach to manage computational resources for consumers in a peer-to-peer style computing grid. In turn buyers and sellers would have access to an electronic trading environment where they could bid for unused compute cycles from a Google Adwords style web interface. Consumers could bid on computing power while Computing Capacity providers offer cost-effective computational capacity on demand, thus creating a competitive computing marketplace.
Although the concept may have been fairly well thought out, it was way too early. For one thing, there was no demand for the service, and the second problem was compute capacity wasn't and still isn't an actual commodity which can be supplied without qualitative differentiation across the greater cloud computing market. Basically there is no basis for an apples to apples comparison.
Wikipedia describes a commodity
Another major limiting factor for treating cloud capacity as a commodity is that there are no standards for cloud capacity and therefore there is no effective way for users to compare it among cloud providers. With out this standardization there is no way to determine optimal cloud capacity requirements for particular application demands and thus determine the optimal price & costing. In order to overcome this, I believe a Standardized Cloud Performance Measurement and Rating System (SCPM) will need to be created which would form a basis of measurement through an aggregate performance benchmark.
As an example a cloud provider may want to use some aggregate performance metrics as a basis of comparing themselves to other providers. For example, Cloud A (High End) has 1,000 servers and fibre channel, Provider B (Commodity) has 50,000 servers but uses direct attached storage. Both are useful but for different reasons. If I want performance I pick Cloud A, if I want massive scale I pick Cloud B. Think of it like the food guide on back of your cereal box. This may provide the basis for determine the value and therefore a cost for the cloud capacity.
This has been one of the motivations behind the creation of an open standard for cloud computing capacity called the Universal Compute Unit (UcU) and it's inverse Universal Compute Cycle (UCC). An open standard unit of measurement (with benchmarking tools) which would allow providers, enablers and consumers to be able to easily, quickly and efficiently access auditable compute capacity with the knowledge that 1 UcU is the same regardless of the cloud provider. (See my previous posts on the subject)
I also believe that the creation of cloud exchanges & brokerage services has less to do with the technology and more to do with the concept of trust and accountability. If I'm going to buy a certain amount of regional cloud capacity ahead of time for my Christmas rush. I want to rest assured that the capacity will be actually available with an agreed upon quality and service level. I also need to be assured that the exchange is financially stable / adequately capitalized and will remain in business for the foreseeable future.
I've never been a particularly big fan of regulation, but given the potential for fraud some oversight may be required to assure a fair and balanced playing field. If we truly want to enable a cloud computing exchange / marketplace another option might be to build upon existing exchange platforms with a proven history. A platform with an existing level of trust, governance and compliance.
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

WebRTC is about the data channel as much as about video and audio conferencing. However, basically all commercial WebRTC applications have been built with a focus on audio and video. The handling of “data” has been limited to text chat and file download – all other data sharing seems to end with screensharing. What is holding back a more intensive use of peer-to-peer data? In her session at @ThingsExpo, Dr Silvia Pfeiffer, WebRTC Applications Team Lead at National ICT Australia, looked at differ...

IoT is at the core or many Digital Transformation initiatives with the goal of re-inventing a company's business model. We all agree that collecting relevant IoT data will result in massive amounts of data needing to be stored. However, with the rapid development of IoT devices and ongoing business model transformation, we are not able to predict the volume and growth of IoT data. And with the lack of IoT history, traditional methods of IT and infrastructure planning based on the past do not app...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

A critical component of any IoT project is what to do with all the data being generated. This data needs to be captured, processed, structured, and stored in a way to facilitate different kinds of queries. Traditional data warehouse and analytical systems are mature technologies that can be used to handle certain kinds of queries, but they are not always well suited to many problems, particularly when there is a need for real-time insights.

Providing secure, mobile access to sensitive data sets is a critical element in realizing the full potential of cloud computing. However, large data caches remain inaccessible to edge devices for reasons of security, size, format or limited viewing capabilities. Medical imaging, computer aided design and seismic interpretation are just a few examples of industries facing this challenge. Rather than fighting for incremental gains by pulling these datasets to edge devices, we need to embrace the i...

Web Real-Time Communication APIs have quickly revolutionized what browsers are capable of. In addition to video and audio streams, we can now bi-directionally send arbitrary data over WebRTC's PeerConnection Data Channels. With the advent of Progressive Web Apps and new hardware APIs such as WebBluetooh and WebUSB, we can finally enable users to stitch together the Internet of Things directly from their browsers while communicating privately and securely in a decentralized way.
