Cloud computing and the challenges and issues for enterprise users, was one of the topics taking center-stage at the NetEvents’ Asia Pacific press summit held in Singapore over this past weekend.

Looking at cloud computing from user perspective, Camille Mendler, vice president-global service strategies for the Yankee Group, beleives that it is popularly understood as a software-as-a- service provided over the Internet and is not hosted by in--house infrastructure. As such, users only pay for actual usage and can avoid unnecessary expenditure.

She adds that large enterprises also stand to benefit by creating their own cloud by consolidating resources into a data center and making it accessible to the corporate wide area network (WAN) as well as the Internet. Whether the data center is consolidated physically or virtually becomes less of an issue than the relationship between the corporate WAN and the wider Internet availability. The entire business moves into the cloud when providing services such as social networking, search engines and auction sites.
Potential to do more without heavy capital expenditure

Because of its flexibility and scalability, cloud computing can address several corporate needs. It can aid in the quest to achieve faster time-to-market. It can also boast responsiveness to fast-changing capacity management, as well as foster a collaborative culture with its social networking features. The fact that info-comm budgets are not increasing but instead are being shifted between cost components makes the pay-as-you-use cloud computing business model attractive to enterprises.

According to Mendler, telecommunications service providers, equipment vendors, software houses, systems integrators and start-ups are all exploring or actively entering this cloud-space. Traditional players, including IBM, Microsoft and Oracle have either announced or are formulating their own plans to ensure that their application deployment platforms also gain a foothold in the cloud.

She adds that it is not only the vendor landscape that is changing, business models are shifting too. Software-as-a-Service (SaaS) vendors who for a long time have been running off their own infrastructure now face tremendous challenges against new entrants on the Internet.
Need to focus on what customers want

Touching on enterprise expectations, Mendler adds that the cloud computing community is not focused enough on customers and they need to improve in their dealings with clients. She believes that the cloud computing community is too fixated about service definitions, standards and technology. A survey of service level agreements gives the Yankee Group grounds to conclude that customers feel there is a lack of trust, transparency and professionalism within the cloud vendor community.
Laws behind on cloud computing

Mendler warns that that exposure of customers to risks which can outweigh the benefits does not reflect well on the industry and raises the flag about the laws and regulation having not kept abreast of the new order resulting from cloud computing. For example, she says that the laws are unclear about data residing in cloud, data moving between cloud and involvement of third parties. There is a need for monitoring services in the areas of privacy protection, data security and jurisdiction, she stresses.

And few cloud vendors, if any, are audited on security, survivability and process controls, Mendler adds. This leads to opportunities for industry players to help secure, test, monitor and orchestrate disparate cloud assets.

By its very nature, cloud computing invariably involves multiple relationships. Hence, there is also a need for trusted intermediaries for inter-cloud services in roles as business rule repository, service level measurement, security authentication and for billing and settlement services, Mendler says. She names telcos like British Telecom, Deutsch Telecom, SingTel and NTT as possible candidates but adds that ‘they won’t do it without help’.

UK Broadband Take-up

UK Broadband connections take top place

Dial-up connections fall dramatically

by Kendrick Struthers-Watson Telecommunications Online

Fri. November 21, 2008

Since the Office for National Statistics (ONS) began its index in 2001, the market share of broadband Internet connections in the UK has been increasing, reflecting its continuing popularity, widespread availability and increasingly competitive connection packages.

According to ONS, almost nineteen out of twenty connections to the Internet are via broadband and in September 2008, broadband connections accounted for 94.1 percent of all Internet connections, up from 92.8 percent in June 2008, resulting in a year on year increase of broadband connections of 7.6 percent.

Despite continuing increases in broadband connections, an 18.6 percent decrease in dial-up resulted on a 0.4 percent fall in the index of all connections between June and September 2008, to 118.4. Dial-up connections continued to decrease with a year on year fall I the index of 49.6 percent to September 2008, giving a quarterly decrease from June to September 2008 of 18.6 percent.

Accelerating speed

The proportion of higher speed connections in the UK continues to increase. In September 2008, 57.7 percent of broadband connections had a speed greater than 2 Mbps which is an increase from 55.8 percent in June 2008. Over the same period, the percentage of connections with a speed of less than or equal to 2 Mbps decreased to 42.3 percent in September 2008, down from 44.2 percent in June.

ONS says that the Internet Service Providers survey is carried out in line with rigorous standards of all national statistics. However, it points out there is no current definitive population of ISP’s from which to sample and therefore the index should be treated with some caution.

The Great Infinite Bandwidth debate

Tue, 04 Nov 2008 16:33:05 +0000

A couple of extracts from the current (October / November 2008) issue of fibre systems Europe placed in juxtaposition just to create some debate.

NOTE: Some minor editing of the articles to remove links to other articles in the magazine.

NEC to supply high-speed GPON solution In Sweden (Page 9)
Customers of Swedish network operator Svenska Fibernat AB will soon benefit from blistering broadband speeds of up to 1 Gbit/s - 10 times faster than was previously available. The upgrade is made possible by high-speed GPON equipment supplied by NEC Europe, which is based on the AM3IOO series Multi Service Access Node. The new service follows a successful trial in the Uppsala region of the country.

So parts of Sweden will get really good Broadband connections, so how does this stack up with ISP performance?

Backbone capacity manages to keep up (page7)
Internet traffic is growing fast, but backbone network capacity is keeping pace. That’s the conclusion of a new report from US consultancy TeleGeography, which has analysed internet capacity on international and major city-to-city routes across the world.
The report found that for the second year running, total international internet capacity grew faster than total traffic, leading to lower use on many internet backbones. Between mid-2007 and mid-2008, average traffic levels decreased from 31 to 29%, while peak use fell from
44 to 43%. Overall internet traffic growth has remained strong, with international traffic growing 53% between mid-2007 and mid-2008 — a less rapid pace of growth than the previous year, when it increased by 61%.
“Broadband subscriber growth has been slowing since 2001, but the volume of traffic generated by each user has grown:’ explained Telegeography’s director of research Alan Mauldin. ‘Growth is fuelled by demand for video delivered via the internet.’

OK - so far the backbone is keeping up? But what of the future?

Brace for impact (Editorial)
Trying to predict the future is a good way to invite egg on face, it but that’s exactly what plenary speakers are expected to do. At the European Conference on Optical Communications (ECOC) in Brussels last month it was the turn of Rod Alferness, chief scientist at Alcatel-Lucent’s Dell Labs.
Alferness kicked off his talk by looking back on the predictions he had made 10 years earlier,at ECOC 1998 in Madrid. Back then 1 Tbit/s of capacity had already been demonstrated, so transmission was viewed as a solved problem. The real issue for the optical networking industry at the time was how to manage and tame all that bandwidth. Mesh and reconfigurable networks based on reconfigurable optical add—drop multiplexers looked like the optimum solution, and in fact that has turned out to be the case, even if it has taken a little longer to arrive than anticipated (no rotten tomatoes so far).
But going forward, increasing transmission capacity will not be so easy, Alferness contends. The industry’s belief that fibre has unlimited bandwidth has been overturned, and some tricky, nonlinear physics is already creating significant challenges for vendors developing high-speed, high-capacity transmission gear. 1 think that in the next 10 years we are going 6 to be very challenged to find the bandwidth that society demands fl of us in a cost-effective way,” he stated. It’s not unreasonable to e suggest that commercial systems in 10 years time will need to offer capacities around 100 times greater than they do today.
Alferness then presented a chart showing how the capacities demonstrated by “hero experiments” are increasing far more slowly than they did before. “In the past we would have said a breakthrough was required,” he observed. This view was echoed by market analyst Dana Cooperson of Ovum in her Market Focus presentation, who displayed a chart showing how capacities available from commercial DWDM systems have also hit a ceiling. Turn to page 14 to find how and why the industry is struggling with the next step up in capacity to 100 Gbit/s wavelengths.
Of course, the challenges over the next few years will go way beyond technology. The US credit crisis is only months old, and yet the shockwaves have spread across the world. When, earlier this summer, I commissioned an article on how the telecoms industry could weather an economic slowdown, nobody had any idea that the whispers in the wind were going to turn into a financial hurricane that would wipe out numerous financial institutions, send the stock market into panic, and cost governments around the world $3.2 trillion (€2.4 trillion) in rescue packages. On page II. industry analyst David Dunphy considers what operators and vendors might do to boost their chances of survival.

Tiscali has confirmed talks with selling to BSkyB

Tue, 04 Nov 2008 12:03:51 +0000

Unreferenced quote extracted from uk.telecom.broadband on usenet.

"Broadband provider Tiscali has confirmed talks over selling its UK business to broadcasting giant BSkyB.

Tiscali currently has 1.8 million broadband customers in the UK - making it the fourth largest player - although its market share is believed to have come under recent pressure.

The Italian firm said: "Tiscali clarifies that it is currently holding talks with the BSkyB Group plc in relation to certain UK assets." The statement came after weekend reports of exclusive talks between the duo over a £450 million deal.

Tiscali has been up for sale since it launched a strategic review in February. Sky put forward an indicative offer of £450 million, according to The Sunday Times, which could make the broadcaster the third biggest player in the market behind BT and Virgin Media.

Carphone Warehouse is said to have pulled out of the bidding. [Thank Christ for that, their servers are overloaded enough already] Other competitors understood to have walked away from the auction include Vodafone and BT.

Vodafone had been seen as a strong bidder earlier in the process, as the group was reportedly the only player interested in buying both Tiscali's UK and Italian broadband operations.

Groups interested in Tiscali's Italian operations are thought to include Wind, Italy's third biggest mobile operator, and Swisscom, which owns Italy's Fastweb.

Tiscali was at one stage expected to fetch about 1.6 billion euros (£1.3bn), with the price tag for the UK business alone seen as being more than £500 million.

BSkyB said on unveiling quarterly results last Friday that its broadband customer numbers had soared to 1.8 million, with one in five Sky customers taking up the service.

Its total customer numbers topped nine million after it added 87,000 new customers in the three months to September 30 in the group's best first-quarter performance for five years."
