As the industry-wide paradigm shift to cloud computing and software-as-a-service gradually continues to make the transition from buzz to reality, security and availability continue to emerge as the main barriers to customer adoption. A recent ISACA survey of over 1,800 US IT professionals found that only 17 percent believe the benefits of cloud computing outweigh the risks. Only one in 10 respondents said they would consider using software-as-a-service (SaaS) for mission-critical applications. more
In a relatively short time, the phrase "in the cloud" has become a term of art when talking about the internet. A quick Google search shows nearly a million uses of the phrase in the past month, a 3x increase from the same period in 2009. But, what does it actually mean to have your web site, your software, your data, or anything else "in the cloud?" "In the cloud" is derived from "cloud computing," which in turn is just a new term for distributed computing, where data-crunching tasks are spread across a variety of different physical processing units. This was common in mainframes in the 1960s, and later the idea of distributing processing across cheap PCs running Linux became popular in the 1990s. more
Recently Bitcurrent conducted a cloud performance test commissioned by my client Webmetrics, a business unit of Neustar. Bitcurrent describes itself as part blog, part analyst firm and part resource site for the web community. The research project was led by Alistair Croll, a well-known name in the space and program chair for the Cloud Connect conference. more
Do you know how big your web site will be in a year? You probably can guess, or even estimate how much traffic will hit your site in a year. You can also use millennia proven methods such as Crystal Balls, Animal Entrails or even Coffee Stains. But seriously, it is no easy task evaluating site growth in this volatile, ever changing economy. A key element in the scaling of any web site is the Application Delivery Controller (ADC). more
As Reddit recently learned it's not a great idea to use the Amazon EC2 cloud to host mailservers. There are a number of reasons for this, most of them related to the reputation of mail coming from EC2 servers. When you're using machines in the cloud, changing IP addresses is as simple as initializing a new server. Spammers discovered this almost as soon as the EC2 cloud became public. more
Werner Vogels, CTO of Amazon, explains how web applications will be built in the future. His point is twofold. The bad news is that expectations for good web applications are sky high. It has to have rich media, available on multiple devices, very scalable, social networking and that is just the beginning. The good news is that a lot of this can be done by services that are readily available on the web, with reasonable usage based pricing. more
Yesterday's Wikipedia outage, which resulted from invalid DNS zone information, provides some good reminders about the best and worst attributes of active DNS management. The best part of the DNS is that it provides knowledgeable operators with a great tool to use to manage traffic around trouble spots on a network. In this case, Wikipedia was attempting to route around its European data center because... more
This article on cloud appeared in the Economist.com on April 12th 2001 titled "The Beast of Complexities" Stuart Feldman of IBM, mentions these examples. Quote 'Picture yourself as the product manager of a new hand-held computer whose design team has just sent him the electronic blueprint for the device. You go to your personalized web portal and order the components, book manufacturing capacity and arrange for distribution. With the click of a mouse, you create an instant supply chain that, once the job is done, will dissolve again." unquote. ...In the same article he also lamented that so far, nobody has found a silver bullet to kill the Beast of Complexity. more
I recently participated in two Comverse events, and once again the message was driven home to me about the enormous opportunities that lie ahead of the industry in the field of new telecoms applications. The middleware and cloud applications that are now appearing at the edge of the network will of course, be further developed once high-speed broadband becomes available, but already they are having an enormous impact on the telecoms market. The new user experiences that can be obtainable through these applications will enrich fast broadband networks beyond recognition. What we now have is, on the one hand, the Over-The-Top (OTT) applications that have conquered the world... more
Cloud Computing is a hot topic. Some say it is already here, most agree that it will be much bigger in the coming years. It is pushed forward by the economic benefits of virtualization and consolidation. Take a heterogeneous data center, full of many kinds of servers, running a myriad of applications and consolidate it into a uniform farm of virtual machines, where each application is services by one or more VMs and you have a cloud, what is called a private cloud. more
