      Hello again and Happy New Year! I’ve just updated my About page ready for 2013. After a break from blogging and with mainstream cloud and “cloud-marketed” services gaining real traction, my goals for this site have changed. Friends and family frequently ask which cloud services, apps and cloud providers I recommend along with how to use them “safely”. Again, […]

      More than with previous technological (r)evolutions a side effect of cloud computing seems to be an increase in the degree of centralisation and concentration, not just within company organisations, but particularly in the wider commercial market. This is the most obvious with Software as a Service, where providers such as AirBNB, Uber, but also earlier clou […]

Five open source tools for building and managing clouds

Posted by brennels on July 14, 2010

Bill Claybrook, Contributor 07.09.2010

Open source technology is going to seriously impact the cloud computing world, and there are two main reasons why: Open source software is essentially free, and it is not generally encumbered by the software license models of proprietary software. Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain old and expensive license models, even though they impede the flexibility gained by virtualization and cloud computing.

A number of open source tools have already had a huge impact on cloud computing: Linux and Xen, for example. But there are other important open source offerings that can benefit cloud users. These include KVM, Deltacloud, Eucalyptus,’s CloudStack Community Edition and OpenNebula.

KVM (Kernel-based Virtual Machine) is an open source hypervisor for Linux running on x86 hardware. It contains virtualization extensions (Intel VT or AMD-V). With KVM, you can run multiple virtual machines (VMs) running unmodified Linux or Windows images. KVM is an upstream hypervisor, sitting in the Linux kernel that converts the kernel into a bare metal hypervisor. Being upstream means that every Linux distribution ships with KVM. As the Linux kernel gets updates, KVM takes advantage of them automatically. KVM is supported in Red Hat Enterprise Linux, Ubuntu, and SUSE Linux Enterprise Server.

Amazon’s early efforts at cloud computing? Partly accidental

Posted by brennels on June 30, 2010

Posted by: Carl Brooks

Former ‘Master of Disaster’ at Amazon Jesse Robbins has a couple of fun tidbits to share about the birth of Amazon EC2. He said the reason it succeeded as an idea in Amazon’s giant retail machine was partly due to his inter-territorial corporate grumpiness and partly due to homesickness–not exactly the masterstroke of carefully planned skunkworks genius it’s been made out to be by some.

Robbins said Chris Pinkham, creator of EC2 along with Chris Brown (and later joined by Wiljem Van Biljon recruited in South Africa)was itching to go back to South Africa right around the time Amazon started noodling around with the idea of selling virtual servers. At the time, Robbins was in charge of all of Amazon’s outward facing web properties and keeping them running.

“Chris really, really wanted to be back in South Africa,” said Robbins, and rather than lose the formidable talent behind Amazon’s then VP of engineering, Amazon brass cleared the project and off they went with a freedom to innovate that many might be jealous of.”

Six Ways To Decide Which “aaS” Is Right for You

Posted by amcanty on April 21, 2010

Making sense of the complex “as a Service” ecosystem

By Max Coburn, Margaret Dawson

The benefits of doing things “as-a-Service” (aaS) and leveraging cloud-based technologies are well-known and documented, such as a low barrier to entry, reduced capital outlay and infrastructure, easy scalability, and device/location independence. Many companies also appreciate the reliability of service and the ability to leverage specialized domain knowledge expertise from an experienced aaS provider.

However, there is still a great deal of confusion about the many different types of aaS and questions remain over how much companies should rely on the cloud. Specifically, when is the right time to turn to aaS rather than build and manage in-house and what are some of the pitfalls that can be avoided when moving to an aaS-based solution?

Leveraging the cloud and delivered as a service, each aaS has the ability to help you do things faster, better, cheaper. The most attractive characteristic of the aaS movement is a flexibility that allows for an incremental or selective approach to deployments. You don’t need to do it all at once, and you can mix and match.

The following is a brief synopsis of current aaS variants, when you should consider them, and what the future might hold for this technology.

First, here’s a quick cheat sheet of three most common aaSes:

  1. IaaS – stands for both Integration-as-a-Service and Infrastructure-as-a-Service
  2. SaaS – Software-as-a-Service
  3. PaaS – Platform-as-a-Service

Integration-as-a-Service (IaaS) is probably the oldest, and has historically been the most stagnant, of the aaSes. IaaS originally functioned as a connector, providing integration for businesses to transmit documents to each other, such as EDI (electronic data interchange) and VANs (value added networks). Examples of this type of business document interchange go back to as early as the 1960s and really took hold during the ’70s and ’80s when early service providers helped companies automate this exchange. IaaS improved substantially once documents could be sent digitally over the Internet.”

Cloud Computing: Early Adopters Share Five Key Lessons

Posted by amcanty on April 15, 2010

By Robert Lemos on Thu, April 15, 2010

“Look, Ma, no data center. Many of today’s start-up companies find cloud services such as Amazon EC2 essential to their business model. You can benefit from the lessons already learned by these early cloud adopters.

While some large enterprises have moved their information-technology infrastructure to a third-party managed service to save costs, small firms—especially startups—have come to rely on cloud services to cut initial outlays and help them focus on the core services and products.

Infrastructure-as-a-service offerings, such as Amazon’s Elastic Computing Cloud (EC2), typically are used by larger enterprises to give research-and development groups flexibility in resources. For startups, eliminating the large capital expenditure of a data center at the outset has allowed many to reduce seed money and keep their burn rates that much lower, says Oliver Friedrichs, CEO of antivirus firm Immunet, which launched its first product last August.

“It’s a big win for smaller companies to leverage the cloud because you are really saving a lot—it is really avoiding a large, up-front investment,” says Friedrichs. “Five years ago, we would have had to build out a data center and the sheer cost of that would have made it much more difficult to launch our business.”

Immunet has no datacenter of its own. Instead, the company uses Amazon’s EC2 to analyze malicious code for patterns that can help its product, Immunet Protect, recognize viruses and Trojan horses. The firm also uses the cloud to keep antivirus service available to its more than 125,000 users, adding new virtual servers as its user base grows.

The cost savings and scalability of infrastructure-as-a-service offerings are well known advantages. Yet, there are others. In interviews, three small companies that use the cloud—and one that does not—share the lessons learned from growing up with cloud infrastructure.

1. From IT management to software development

Foregoing a datacenter immediately saves small companies a significant cost: Server administrators and datacenter managers. Yet, rather than reduce headcount, many companies are instead using the reclaimed budget to invest in software developers that have experience working in the cloud.

“In a traditional data center, we would need an IT person to rack the system, maintain the servers, and own the hardware,” says Immunet’s Friedrichs. “So rather than hiring someone, we now have software developers that are writing on a very flexible platform that Amazon maintains.”

For sales forecasting and analytics firm Right90, the cost savings of moving its infrastructure to the cloud was too advantageous to ignore. Right90 didn’t start its business using third-party infrastructure, but the cost savings and flexibility of cloud services beckoned. Last year, the company moved out of its data centers in Calgary, Ontario and San Francisco, California and adopted Amazon EC2 with backup to servers located at the firm’s own offices. The lack of servers to manage has freed up Right90’s IT management team, says Arthur Wong, the firm’s CEO.”

Cloud Computing: What It Is and How to Use It

Posted by amcanty on March 3, 2010

An in-depth look at the types of cloud as a service and how to utilize the cloud for business continuity.

By Brace Rennels

If you listen to the IBM advertisements on television “The Cloud” is described as a “workload optimized service management platform” but what does that mean? Basically, in the most simplistic form, the Cloud is a virtual data center. That is it! People often ask me to explain what it is, how it is used and why is it so popular? Usually, to avoid the deer in the headlights look by trying to explain what an optimized workload is, I will usually explain that it is a virtual data center. However, there are unique characteristics that allow it to be referred to as the Cloud. First, it is usually fully virtualized and accessed via the internet (or cloud), whether it is a virtual private or public network. The technical concept actually isn’t new. Companies have been implementing their own virtual private data centers for years. However, now companies are looking to adopt cloud computing as a service to help reduce costs as well as time to implement new infrastructure, service platform or software application. One of the fastest growing areas of cloud services is utilizing it for disaster recovery and or improving recovery time objectives for storage backup processes.

Most, if not all, Fortune 500 companies have had the Cloud for years. Basically, they have created their own virtual data center for disaster recovery or for centralized server management. These are considered virtual private data centers versus what the Cloud is typically referred as a virtual public data center, like Amazon, where services, platforms or infrastructure is accessed via the Internet. Google has been the “Software as a Service” (SaaS) model for years and is a way to access legal briefings and decisions for research. Lexis-Nexis® is probably the most notable provider of these types of services, they provide thousands of law firms worldwide with of content-enabled workflow solutions specifically tailored to professionals in the legal industry. Therefore, it essentially becomes a commodity type of service that you lease for as long as you need that information or service.

Another benefit of the Cloud is its ability to be utilized as a disaster recovery facility to enhance backup and recovery requirements. For smaller businesses the cost to create a data center is usually too expensive, therefore many companies don’t have the business continuity they would like. With the introduction of Cloud, it became more cost effective for SMB’s to lease infrastructure for disaster recovery rather than gathering funds required to make a purchase all at once. Another benefit in leasing infrastructure is that the company doesn’t need to acquire resources or staff to manage the additional datacenter. Also, a company only needs to pay for what it uses. The Pay-as-you-go model may have one of the largest advantages of utilizing cloud services. So, rather than purchasing all the equipment needed for a data center with three years of storage, the Cloud leases what you need and expands dynamically if more storage, processing or memory is required.

Only paying for the storage you need is what makes cloud providers like the Amazon EC2 an attractive backup and recovery option. Cloud computing can now provide a more readily available copy of data that can be recovered anytime and anywhere. It can also greatly reduce the recovery time objectives of using a tape archive solution. Company’s today are using cloud computing to enhance their existing backup solutions to reduce the amount of money spent on the tape, storage services and shipping but also reduce the amount of time it would take to recover. Tape has been around for a long time so I don’t see cloud computing replacing tape backup anytime soon. However, it will definitely be used to improve business critical servers that need a lower recovery time. Tape can still be used as an offsite archive solution to meet industry compliance regulations, such as when documents and data need to be available for upwards of 7 years before they can be destroyed.

So, what have we learned about the Cloud? It is a virtual data center that can dynamically add resources as needed in a Pay-as-you-go leasing model. But the real difference is how a data center is built, managed and utilized by companies. Cloud computing provides infrastructure, software and platforms as a purchasable service that would not be an option for most companies The cloud provides opportunities for companies to rapidly spin up data center resources without the need for knowledge experts, software administrators and hardware startup costs. The three functions that cloud computing can provide is serve as a disaster recovery facility, a platform and infrastructure for enhanced backup procedures as well as the ability to lease software as needed versus trying to disrupt the company organization to implement yourself. This is only the tip of the iceberg regarding cloud computing, over the next few years this industry will rapidly grow. In fact, it forecasted by many analysts as being a 25 billion dollar business opportunity.

The Different Types of Cloud as a Service
The next step in understanding the cloud is to comprehend the different types of services offered and how to use them.

Innovation and Risk in the Clouds

Posted by amcanty on February 11, 2010

The relationship between innovation and risk is closely intertwined (Part 1 of 3)

By Ray DePena

February 10, 2010 01:30 PM EST

“Do you have reservations about cloud computing?  You are not alone.  Cloud computing is no panacea.  You may wonder then why I’m a cloud computing advocate.  Well, simply put, it has the best business model potential I have seen in the marketplace since the advent of the Internet.

While it is true that the underlying technologies have existed for some time, they have now matured to a degree that SaaS, PaaS, and IaaS economic business models are viable.

Still many have doubts.  So I will share my perspective in a 3 part article on Innovation, Risk, and Organizations.

The relationship between innovation and risk is closely intertwined.  In innovation there is opportunity, and opportunity rarely presents itself without threats or risk.

In order to fully leverage cloud computing, organizations will have to restructure not only how they manage their applications and IT governance, but their business processes, people, resources, risk, communications, and ultimately, their organizational culture.

Andy Grove, former Chairman and CEO of the Intel Corporation, declares that a corporation is a living organism; it has to continue to shed its skin. Methods have to change. Focus has to change. Values have to change. The sum total of those changes is transformation.

Cloud computing is more than just another outsourcing option, it presents an opportunity to transform your organization into an innovation powerhouse.

The question is, will your organization make the transition?

It is true, an organization has to have the people, resources, culture, processes, and strategic focus necessary to be innovative and continually transform, but what is the alternative?  Stagnation? Obsolescence? Being left behind? Isn’t it better to establish and sustain an innovative business advantage than to be in continual pursuit of the mythical silver bullet?”

Cloud 101 – The Four Types of Cloud Services?

Posted by brennels on February 8, 2010

When the term cloud computing first generated a buzz it was typically referring to utilizing software as a service or otherwise known in the industry as (SaaS). Google is probably most known software as a service but then others in the social media industry rapidly shot up like Facebook, Twitter and My Space as well as other hosted applications that were more business critical. Although SaaS was one of the first technical adoptions of the cloud in the last few years, Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) have also become viable solutions and maybe more beneficial to companies than just software.

Software as a Service (SaaS)

Other than the search engines like Google, Bing or Yahoo what can these (SaaS) models do to help a company. The Social Media applications are quickly replacing traditional marketing like print advertising so this is one area but there are many other SaaS available that can help improve efficiency and productivity. Anything from website hosting, content management and or just a dependable database for backend infrastructure are all available for a quick deployment.

Platform as a Service (PaaS)

Platform as a Service is more popular and mostly utilized by the developer community and was likely started with the introduction and popularity of Linux open source code. This cloud computing model provides a platform for developers to code, test and experiment new software without the complexity of setting up and maintaining test, development and production servers.

Infrastructure as a Service (IaaS)

Infrastructure as a service is probably where many large companies like HP, IBM, Amazon and Rackspace are focusing their attention. This service model provides both companies as well as consumers the ability to utilize already optimized and maintained virtualized resources at a data center via a web service or VPN connection. Many will use this to backup, recover data files and or full servers in the event of a loss and that resource needs to be recovered. It can also serve as the primary server and actually run the application workload from this location alleviating the company IT staff of having to procure and or maintain the server infrastructure and or application expertise to provide that service. This is typically billed on a per use basis so only the resources, processing and or storage used is billed at the end of each month.

These are the big three but is there a forth that is already in progress. It is already being adopted by some companies as well as being discussed and that is Recovery as a Service (RaaS). Stay tuned for the next blog post Cloud 101 – Recovery as a Service: How it works

2010 Prediction: Dave Demlow, Double-Take Software

Posted by amcanty on December 10, 2009

2010: Looking Into the Clouds

In 2010 we will see increasing interest and activity around cloud provided infrastructure as a service (IaaS) providing on-demand, pay as you go access to scalable compute and storage infrastructure. Clearly IaaS will not be the only area where services will be provided by the cloud, but it’s getting so much attention because it is a model that can be easily understood by most people, can evolve from and work with existing enterprise applications and architectures and can be quickly and easily trialed in low risk areas such as test or development and expanded incrementally. In addition, there are already a surprising number of providers to choose from with similar but differentiated service offerings and pricing models that can meet a variety of market needs.

I say IaaS is easily understood because when it comes right down to it, it’s all about virtual machines which by now are very well understood. Package up your operating system and application stack into a nice portable container, and run that container on a shared infrastructure but isolated from other workloads sharing the same infrastructure. The next logical question is whether to own the all the infrastructure to run those containers, which depends on the nature and longevity of the workloads, the utilization of existing infrastructure, geographic constraints (sometimes), compliance, legal issues, management preference, and of course, cost. I expect for the foreseeable future that most companies will want to have a mix of internal and external infrastructure to meet the changing needs of various workloads.

 As a software developer, and particularly as the developer of software commonly used to replicate, failover and recover these “workload containers” (whether they are already virtualized or not) from one geographic location to another, we have been very early cloud watchers and users ourselves.

 In addition to the test and development benefits that most software companies can receive by utilizing cloud infrastructure resources to run virtual machines in the cloud at least for peak demand times or special ad-hoc projects, being able to test things like cross country or trans-Atlantic data replication using virtual machines distributed across multiple clouds, purchased just for the time we are using them is fantastic. Of course, it also makes you start to think about many other possibilities.

 Within a datacenter or corporate WAN, there are tools like ours available that can continuously backup and failover workloads on physical or virtual servers into virtual machines (P2V and V2V failover) in different locations for disaster recovery and high availability. If IaaS can allow me to run virtual machines and standard operating systems and applications, can I use it as a recovery site and actually failover workloads from my datacenter to the cloud?  Sure, with the right networking and technologies, it’s certainly possible (and available). Coincidentally this mirrors the same thought processes and customer adoption that we saw early on when server virtualization itself was first limited to test environments, then moved to disaster recovery which gave people the confidence to start moving production workloads into their virtualized infrastructure.

As if by cloud magic…

Posted by brennels on August 19, 2009

I read this post recently from VMlover and thought it was pretty entertaining and worth shareing. Certainly as the Cloud becomes a more adopted platform there will be a need for migrating workloads across virtual public and private cloud infrastructure. The more interesting question is however, will the Virtualization vendors come together for a standardized platform that will allow cross virtualiziation platform movement?

As if by cloud magic…By: VMlover

“Since my last post where I discussed the Microsoft Azure cloud service and highlighted that I felt companies competing in the cloud space such as VMware are now diversifying past the Hypervisor to reach aspirations of Cloud, and then Vmware go and do me a favor and make me look like i’m a visionary and extrememy intelligent and buy Spring Source!!!.

I have had all week to digest the views and opinions from various Industry analysts and bloggers and see what they are thinking and saying in general on the Spring acquisition and now heres my attempt (ARSE COVER DISCLAIMER – I am not a Software Architect/coder/guru/white sandals & sock wearer so excuse any rubbish) at trying to predict where the purchase will lead VMware’s current business model and what will evole from the acquisition, lastly I also highlight what the industry needs from any of Vmware’s clouds offerings.”
