Hip? Or Hype? Load and Performance Testing from the Cloud

Mon, 21 May 2012 12:01:00 EDT

Assuming you haven’t spent the last couple of years living under a rock, you’re bound to have been bombarded with all sorts of propaganda about “The Cloud.” “The Cloud,” according to the marketing types, is the greatest thing since the invention of bread, surely able to solve all of our needs, whether technology-related or not. While the hype for the cloud might be frequently and frustratingly overstated and confusingly applied in odd places (can someone please explain to me the Microsoft Cloud commercial where the woman goes “to the cloud!!” so she can generate a family photo? What does this have to do with the cloud? Isn’t this just Photoshop?), I’d like to discuss one place where the cloud adds a great deal of value: Load and Performance testing. In this article, I’m going to talk about the benefits of using the cloud as part of your load and performance testing practices, as well as point out some common approaches in choosing a cloud solution. In a future article, I’ll discuss some of the challenges the cloud presents and some best practices to deal with these challenges.

The Cloud and the Changing Role of the Investor

Mon, 07 May 2012 06:15:00 EDT

Tech entrepreneurs can see clearly now; the rain is gone, thanks to the cloud. Cloud computing is making it easier and more affordable for people all over the world to be entrepreneurs, and individuals and businesses are acting accordingly.

Four Ways to Look at Cloud Computing

Sun, 06 May 2012 08:00:00 EDT

Like other trends in technology, cloud computing is constantly being redefined and re-understood. The fact of the matter is that, while we have a general agreement on what cloud computing is, the term has come to mean many things to many people. The advent of cloud storage services and even Apple’s iCloud has only served to further muddy the waters, even in IT.

In the most basic sense, cloud computing refers to the use of an app or service that’s hosted in a non-traditional, non-server-based manner. In that sense, however, cloud computing is very broad, and perhaps that’s the right approach.

Here are some ways we commonly look at cloud computing, not all of which are completely compatible with one another:

Cloud computing as the way to solve past IT mistakes. For years, pundits have pushed cloud solutions as a way to get IT out of difficult situations. While that may be true, not all previous IT decisions that didn’t work out correctly did so because they didn’t use the cloud.
Cloud computing as data center outsourcing. There is a sense in which using cloud solutions allows an organization to outsource many of its data center functions. That being said, there are some basic IT services that will – and should – forever be housed internally. Add to that the fact that internal clouds are an option, and this definition makes less and less sense.
Cloud computing as virtualization. Virtualization has certainly made its impact on IT and the data center, just as cloud computing has done. Good cloud implementations will rely on virtualization technologies, but the two are not coterminous. There are some cloud solutions that shouldn’t run in a virtualized environment, and virtualization doesn’t automatically put something in the cloud.
Cloud computing as Internet based solutions. From the consumer perspective, cloud computing seems to be the use of specific services via the Internet. Certainly, you can make a case that online storage providers, or even implementations like QuickBooks Online are the only cloud solutions many consumers will ever see.

At its core, cloud computing is about the correct use of IT resources, about mitigating risk, and about providing users with the solutions they need when and where they need them.

Tutorial: Build a Private Cloud in Twenty Minutes

Wed, 02 May 2012 06:00:00 EDT

OpenStack is an open-source cloud framework for building on-demand Infrastructure as a Service. This tutorial in essence distills from this two-page set of instructions for setting up devstack on a single server primarily for use by developers. I used a DELL 1950 with 8 GB of RAM, internal hard-drives and two 1000 MB NICs. Download and Set Up Ubuntu Download Ubuntu 11.10 from here and burn to DVD Boot the server from the DVD and start the install. I installed the BASE SYSTEM and only one optional package, the OpenSSH Server. I named my server "ubuntu-server" I configured eth0 with a static ip address of 10.202.181.21. This will be important as the HOST_IP address of devstack. Create a user named "stack". Log in as "stack"

The New Holy Grail: Application Portability in the Cloud

Fri, 13 Apr 2012 08:00:00 EDT

Today’s enterprise is built on the promises of mobility, everywhere-access and flexibility. We work on multiple devices when and where we want – at the office, on the road or at home. We expect full access to our data and applications – on a sales call, in a boardroom or on a cross-continental flight. And we expect to be able to transfer our data seamlessly between platforms –on a mobile device, on the desktop or in the cloud. Why should enterprise cloud application data be any different? Enterprises housing apps in the cloud should expect to be able to position application data to optimize service, ensure regulatory compliance and preserve privacy. Application portability is a mission-critical demand of the real-world enterprise, and yet it’s a need left unfulfilled by public cloud providers.

Mon, 02 Apr 2012 05:45:00 EDT

Cloud computing has caught the attention of business leaders around the world in every industry because of its enormous transformative potential. Visionary companies know that the value of the cloud is far greater than the current focus solely on technology and operating costs: when combined with a collaborative approach to designing processes, cloud computing will change how we do business.

CloudBerry Backup How-To: Restoring Only Newer Files

Tue, 06 Mar 2012 05:45:00 EST

Sometimes you may want to restore the newer version of the file on the target computer over the existing (Older) version. This is particularly important in the Sync scenario, where you want to have your target folder look exactly as the source. In the previous version of CloudBerry Backup that would not be possible and you could just force overwrite every file in regardless of the modification date. This would cause a lot of unnecessary restore operations.

As always we would be happy to hear your feedback and you are welcome to post a comment.

Five Steps to Creating a Governance Framework for Cloud Security

Mon, 28 Nov 2011 08:15:00 EST

Cloud computing has revolutionized the way organizations around the world use technology. Despite the fact that many refer to 2011 as the Year of the Data Breach, and cloud computing has earned a reputation of being inherently insecure, that stigma is simply just not true. Most cloud providers have much higher security measures for their systems than even the most sophisticated IT departments can afford to deploy. The perceived lack of security comes from the mismatch between on-premise security assumptions and the expanded needs driven by the use of cloud. Cloud computing is a significant technology trend that is set to dramatically change the nature of business. We have witnessed a recent spate of high-profile security attacks and data security breaches – from Amazon to Epsilon – and as worrisome as these incidents are, they are not as worrisome as the reputation of cloud computing being insecure. In fact, cloud computing seems to have become a scapegoat for failed security measures. On closer examination of some larger incidents, it’s clear that many data breaches are a result of inadequate cloud security practices.

Breaking the Storage Array Lifecycle

Mon, 03 Oct 2011 11:45:00 EDT

Anyone who purchases storage arrays is familiar with the many advantages of modular storage systems and storage area networks. However, they may also be familiar with one of the less desirable attributes of storage arrays: the typical three- to five-year lifecycle that forces decommissions and mandates upgrades on a regular basis. With many organizations expanding their need for storage by 20-60% on an annual basis [1], outgrowing capacity of existing storage arrays is a regular occurrence, effectively rendering upgrade cycles to be a fact of life. Although decommissioning and upgrading a storage array may not appear all that daunting, the process includes a number of cumbersome aspects.

Unleashing the True Power of Cloud Computing

Fri, 30 Sep 2011 07:00:00 EDT

The first generation of cloud computing was revolutionary in that it added business value to organizations by reducing development time, eliminating the need to procure infrastructure, providing massive scaling potential, establishing scale through multi-tenancy and by allowing IT people to focus on solving business problems versus technical ones. As cloud-based applications grew in prominence, they fought to achieve parity with legacy on-premise software solutions that were feature/functionality rich. These goals were achieved in short order, and thus the new generation of cloud solutions was born. Web 2.0 goes far beyond parity with legacy systems and leverages the power of information sharing, collaboration and the social grid to achieve value that would be impossible with a paradigm of pushing information out from a single location. The new age cloud applications are powerful because they break down silos and simplify the process of converting data into information. As Web 2.0 systems in the consumer space evolve, companies are taking notice and looking to unleash the same power in their enterprise applications.

A Four-Stage Journey to Cloud Computing

Thu, 08 Sep 2011 10:30:00 EDT

For almost a decade now, organizations of all sizes have been leveraging server virtualization, but few have fully gained the flexibility and efficiencies it promised. The emergence of cloud computing and the promise of delivering on-demand resources has introduced new challenges and opportunities. A company’s level of virtualization adoption maturity correlates to its readiness to deliver an on-demand, real-time infrastructure through a private cloud. An effective virtualization and cloud management solution can ease the journey toward that end.

Steps for Improving Capacity Management in the Age of Cloud Computing

Tue, 06 Sep 2011 16:00:00 EDT

When you wake up in the morning and flip on a light switch, you don’t think about whether the local power company has enough electricity available to power the light. Likewise, when you switch on the coffee pot or turn on your stove to make breakfast, you don’t wonder about the available capacity of your local power grid. Similarly, cloud computing is rapidly making the delivery of business services second nature to business users. They are able to access the services they need, when they need them, because the dynamic nature of the cloud offers unprecedented, highly elastic computing capacity.

IT as a Service Broker – Adopting a Hybrid Delivery Model

Mon, 22 Aug 2011 09:00:00 EDT

The “cloud era” of information technology is upon us. Connectivity is pervasive and everyone and everything is connected. Readily available, low-cost, Internet-based services providing access to new capabilities and infinite amounts of information have given rise to a new set of experiences and expectations for technology users. Furthermore, a new generation is entering the workforce, one that has grown up with technology at their fingertips, one that expects immediate gratification and instant results and one that is ambivalent to traditional IT controls. These tech-savvy business users are mixing the technology experiences from their consumer lives with those of their profession to morph into a new “prosumer” workforce. And they are able to drive game-changing innovation without a dependence on IT intervention. This is the reality of the cloud computing economy; it’s the forcing function behind the creation of new goods and services, new business models, new routes to market, and new ways of engaging customers. Simply put, cloud services are the enablers for the next frontier in business and government, one where technology-enabled services are easily sourced and woven into the enterprise fabric. However, cloud sourcing can also introduce new levels of complexity and business risk without the appropriate levels of integration and governance. This has given rise to a new class of service provider – the cloud service broker.

Cloud Computing & Virtualization: Hot Trends Organizations Can’t Ignore

Sat, 20 Aug 2011 12:00:00 EDT

The use of virtualization and cloud computing is growing quickly among companies of all sizes. Currently, 30 percent of servers are virtualized, and surveys show that by 2012, that number will grow to 50 percent. Virtualization and cloud computing go hand-in-hand, and virtualizing servers is just the tip of the iceberg. The trend to virtualize everything from servers to processing power to software offerings actually started years ago in the personal sector. In the recent past, it was common for individuals within major organizations to use virtualized services or cloud computing when at home, but at work they weren’t using those services at all. Why? Because corporate IT didn’t trust the lack of security of the cloud and they weren’t sure it was a hard trend – something that was definitely here to stay. Today, we know better.

Building a Cloud Factory

Sun, 14 Aug 2011 05:45:00 EDT

Few areas of human endeavor can match the pace of change in IT. Even by IT standards, the change being driven by cloud computing sometimes seems surprising. To refer to a virtual environment that has only recently been deployed as “legacy,” as some organizations are now doing, underscores the fact that the only thing constant in the data center is change. To deal with change of this magnitude, which can involve transforming the workload hosting model of an entire organization, some industrial-strength thinking is required. In order to tackle this challenge, it’s important to properly frame the cloud transformation problem. Many associate cloud with agility, flexibility, cost transparency and other end-user-oriented benefits. But many of these attributes are primarily associated with new infrastructure requests, and specifically, the use of self-service portals to “spin up” infrastructure to host new applications or host transient processing demands. When it comes to migrating hundreds or thousands of existing workloads into cloud infrastructure, agility is not a benefit that is typically experienced. In fact the opposite is often the case: because clouds require a higher degree of standardization (i.e., a finite catalog of sizes and software options), migrating existing physical and virtual servers into cloud models can actually be quite difficult. In other words, the very features that make clouds agile for new workload deployments can actually make them less agile from a transformation perspective.

It’s a Brave New World for Business Intelligence

Wed, 03 Aug 2011 14:15:00 EDT

It’s no secret that today’s IT professionals need to help their organizations capture, track, analyze and share more information than ever before. From mass quantities of transactional data, Web data, and huge and growing volumes of “machine-generated” information, such as sensor and log data, volumes are expanding into the terabyte (and even the petabyte) range. At the same time, the way end users consume information is rapidly changing. Thanks to innovators like Facebook, Twitter and LinkedIn, social computing technologies are spreading like wildfire, and companies are starting to look at how to harness social networks, blogs, wikis and more to share business intelligence and collaborate more effectively. As the data center strains under the need for more storage and faster performance (all while keeping costs in check,) cloud computing, open source technologies and other emerging approaches are presenting compelling new ways to manage data and consume IT services. How can IT practitioners best navigate today’s rapidly changing BI landscape?

Testing the Cloud

Wed, 27 Jul 2011 10:45:00 EDT

Cloud computing has now passed the stage of hype to reality. More and more enterprises are realizing the benefits of remote hosting of IT services rather than local IT management, especially as managing and operating IT networks and services is not getting any easier. Managing IT networks requires a broad set of competencies in a growing number of technologies and products. It therefore makes sense that these competencies are centralized in larger data centers providing cloud services to a number of smaller enterprises for which IT is not a core competency. Larger data centers also means larger installations with higher-speed interfaces as well as an obligation to maintain service availability. This requires extensive test and management capabilities to ensure service “up-time.” However, will test and management of cloud services differ from how they are performed today? What are the special challenges that cloud service providers face in this regard?

Risk and Its Impact on Security Within the Cloud - Part 1

Wed, 27 Jul 2011 09:15:00 EDT

These days when we hear the term "cloud computing" there is an understanding that we are speaking about a flexible, cost-effective, and proven delivery platform that is being utilized or will be utilized to provide IT services over the Internet. As end users or researchers of all things "cloud" we expect to hear about how quickly processes, applications, and services can be provisioned, deployed and scaled, as needed, regardless of users' physical locations. When we think of the typical traditional IT security environment, we have to be cognizant of the potential for an onslaught of attacks, be they zero day, the ever-evolving malware engines and the increase in attacks via social engineering, the challenge for any security professional is to develop and ensure as secure an IT system as possible.

Cloud Computing: Opportunities for Communication Service Providers

Mon, 25 Jul 2011 14:15:00 EDT

Cloud Computing is an evolution of existing technologies to deliver services to end users. Communication service providers have an early adopter opportunity to compete with new entrants, increase their bottom line and play a dominant role in delivering cloud services. Service providers have seen many so-called next- generation technology waves in the last 15 years. Cloud computing, which was seen as a new fad, has passed the initial test. Cloud computing is for real and not a vague idea anymore. It helps drive down costs for IT organizations by making infrastructure more distributed, more efficient and massively scalable. It’s being accepted by enterprises of different sizes as a smarter way to deliver services. The worldwide cloud computing market is growing fast. According to IDC, it will be a $148.8B market by 2014, of which the public cloud alone would be about $55.5B. Communication service providers (CSPs) have made a significant investment in technology, people and processes. They have customer knowledge and relationships. Public cloud computing offers a unique opportunity to CSPs to defend their hosting business and grow significantly by focusing on a much larger market than what they can do today. This article focuses on some of the areas where CSPs have an advantage over others to take the lead market share in public cloud computing.

Four Steps to Compliance Management in the Public Cloud

Thu, 21 Jul 2011 11:30:00 EDT

Feeling nervous about the cloud? Many CIOs understandably hesitate to send services requiring regulatory compliance to the public cloud. Though not outsourcing such services may seem like a good idea, this approach limits your flexibility in offering the best combination of services to meet business demands. As public cloud services continue to grow in both diversity and quality, IT and the business can’t afford to bypass opportunities offered there and hope to remain competitive. The compliance issue must be addressed, but how? Is it possible to ensure compliance when sending services to the cloud? Fortunately, the answer is “yes.” By using a strategy based on Business Service Management (BSM), a comprehensive approach and unified platform for running IT, you can extend the BSM processes and solutions that you use to manage your internal infrastructure to the public cloud environment.

Book Excerpt: Making Software a Service

Thu, 21 Jul 2011 10:00:00 EDT

Developing your Software as a Service (SaaS) takes you away from the dark ages of programming and into the new age in which copyright protection, DMA, and pirating don’t exist. In the current age of computing, people don’t expect to pay for software but instead prefer to pay for the support and other services that come with it. When was the last time anyone paid for a web browser? With the advent of Open Source applications, the majority of paid software is moving to hosted systems which rely less on the users’ physical machines. This means you don’t need to support more hardware and other software that may conflict with your software, for example, permissions, firewalls, and antivirus software. Instead of developing a simple desktop application that you need to defend and protect against pirating and cloning, you can develop your software as a service; releasing updates and new content seamlessly while charging your users on a monthly basis. With this method, you can charge your customers a small monthly fee instead of making them pay a large amount for the program upfront, and you can make more money in the long run. For example, many people pirate Microsoft Office instead of shelling out $300 upfront for a legal copy, whereas if it were offered software online in a format such as Google Docs, those same people might gladly pay $12.50 a month for the service. Not only do they get a web-based version that they can use on any computer, but everything they save is stored online and backed up. After two years of that user paying for your service, you’ve made as much money from that client as the desktop version, plus you’re ensuring that they’ll stay with you as long as they want to have access to those documents. However, if your users use the software for a month and decide they don’t like it, they don’t need to continue the subscription, and they have lost only a small amount of money. If you offer a trial-based subscription, users can test your software at no cost, which means they’re more likely to sign up.

In the Service Oriented Cloud, All Roads Lead to SOA

Fri, 01 Jul 2011 09:45:00 EDT

Cloud Computing is intrinsically service-based. But this is not just in the highly generalized sense of the term ‘service’, but also in the more specific Service Oriented Architecture (SOA) use of the term, where capabilities are provided via published service interfaces. In this research note we consider why SOA should not be forgotten just because more fashionable terms have risen to the top of the toybox. It might be easy to conclude that SOA was yesterday’s issue. In fact according to some pundits SOA is dead and business transformation, application and IT modernization, and Cloud Computing are more fashionable terms today. But SOA hasn’t gone away! Achieving business improvement, modernized applications and leveraging cloud computing requires a solid foundation based on SOA. Most larger organizations have already adopted SOA to some extent, but few have achieved the critical mass that delivers on the original SOA vision. Moreover, organizations need to understand that all roads still lead to SOA. This is the key architectural style that is intrinsic to all strategic initiatives that will deliver radical improvements in cost and agility.

Book Excerpt: Service-Oriented Computing Fundamentals

Mon, 27 Jun 2011 11:45:00 EDT

This excerpt describes fundamental terms and concepts associated with service-oriented computing, including those related to service-oriented architecture, service-orientation, and cloud computing. Service-oriented computing is an umbrella term that represents a new generation distributed computing platform. As such, it encompasses many things, including its own design paradigm and design principles, design pattern catalogs, pattern languages, a distinct architectural model, and related concepts, technologies, and frameworks. Service-orientation (explained shortly) emerged as a formal method in support of achieving the following goals and benefits associated with service-oriented computing.

Cloud Expo Day Four: Still Very Cloudy in New York

Thu, 09 Jun 2011 07:00:00 EDT

The economics of the cloud, the rise of the mobile workforce and the consumerization of IT are making the transformation to the cloud a foregone conclusion within enterprise IT. But not every company, organization or government agency is necessarily keeping up. Are you?

In Cloud We Trust?

Fri, 08 Apr 2011 12:00:00 EDT

‘In God we trust,’ yet the currency of the Cloud is at odds with trust. Is it possible to trust applications that reside in a Cloud that seems so porous? Cloud Computing Journal sat down with GuardTime CEO Mike Gault, whose keyless signature technology is used to secure cloud hosting provider Joyent, whose customers include LinkedIn, Gilt, and Twitter.

From Virtual Machine to Cloud Deployment: An Appliance Deployment Guide

Tue, 05 Apr 2011 11:45:00 EDT

The one sure constant in the application deployment space is change. Over the last decade, many software OEMs have gone from shipping only packaged software to offering turnkey physical appliances, and more recently to providing packaged virtual appliances. The evolution from packaged software to appliance deployments, both physical and virtual, gives end users and IT departments a more streamlined approach to deploying and managing specific services in their environments, leading to better customer experiences and reduced support costs. So what changes when virtual appliances move to the cloud? More and more, customers are looking to move services into the cloud to reduce their physical infrastructure and cost. Several things change, however, when customers no longer control the physical hardware on which their critical services run. Moving virtual appliances into the cloud requires new strategies for development, provisioning, maintaining, and updating virtual appliances. In this article we will discuss the four core elements required for moving virtual appliances to the cloud and how software OEMs and ISVs can achieve cloud migrations with minimum impact on their development resources.

Forecasting Conditions for the 2011 Data Center

Thu, 17 Mar 2011 14:45:00 EDT

They say you can’t predict the weather. Like so many clichés, however, this one isn’t quite true. Meteorologists have a host of tools at their fingertips that help them recognize, track and analyze weather patterns in order to support predictions that are often accurate, or at least reasonably close. The same is true in the computing industry, where patterns emerge in data centers and enterprises much as cloud formations become apparent in the skies. With a careful eye and extensive knowledge informed by years of experience and frequent conversations with frontline IT professionals, we can predict future trends with a relatively high degree of accuracy. The beginning of a new decade is an opportune moment in which to forecast where virtualization – the primary IT initiative of our time – will encounter stormy weather and where it might be welcomed by clear skies.

Latency: The Achilles Heel of Cloud Computing

Wed, 09 Mar 2011 10:15:00 EST

Today, cloud computing is proliferating. For IT and corporate business units alike, there is strong interest in deploying applications in a cloud environment for its increased business flexibility and cost savings. However, common cloud computing solutions can introduce unexpected costs associated with the broader issue of latency from the cloud edge to the end user. IT and individual business units tend to focus on the aspect of performance within the cloud environment when deploying applications to the cloud, rather than the question of performance and reliability of the overall application and content delivery chain from the cloud environment to the end user. This is a serious miscalculation for two reasons. First, the cloud computing provider’s choice of network carrier shouldn’t penalize the cloud user when network performance is degraded. Second, end users will abandon applications and websites based on the smallest performance delays or downtime, jeopardizing the perceived value of the cloud initiative. For these reasons, it is critical that the discussion around cloud latency shift away from IT or business unit-defined acceptable levels of latency to end-user behavior judgments as to what level of latency is acceptable.

Building the Next-Generation Datacenter – A Detailed Guide / Stage 4

Tue, 01 Mar 2011 15:15:00 EST

In parts one, two and three of this article, we provided a brief overview of the CA Technologies virtualization maturity lifecycle, and focused on the server consolidation, infrastructure optimization, and automation & orchestration stages of the lifecycle. The capabilities described in each of those stages provide an essential foundation for a dynamic datacenter, which is an IT environment that not only supports the business but, at times, is part of the product delivered by the business. It is an agile IT environment, built on top of an optimized and automated virtual infrastructure, that is: Service oriented: Delivering on-demand, standardized services to the business (internal customers, partners, etc). Scalable: With the ability to span heterogeneous physical, virtual and cloud environments. Secure: Providing security as a service to internal / external customers.

Instant-On Enterprises & Cloud Computing

Tue, 15 Feb 2011 06:15:00 EST

HP’s strategy is centered on empowering both commercial and enterprise class cloud computing. Research from HP indicates that senior business, government and technology executives believe that by 2015, 18 percent of their IT delivery will be through the public cloud and 28 percent by the private cloud. That leaves the remainder of IT delivery to be handled by traditional delivery methods, either managed in-house, outsourced, or both.

Is Hand-Coding Becoming Obsolete?

Mon, 14 Feb 2011 07:45:00 EST

Increasingly, IT managers, CIOs and software developers are turning to a new approach for rapidly building robust database applications without programming - application generators. Today’s business environment demands managers find ways to do more with less, and application generation allows both developers and non-developers to build applications quickly and efficiently. Application generation tools build database-driven applications that can be deployed to the Web, the Cloud, or to Microsoft SharePoint environments.

Building the Next-Generation Datacenter - A Detailed Guide / Stage 3

Mon, 14 Feb 2011 06:15:00 EST

In parts one and two of this article, we provided an overview of the CA Technologies virtualization maturity life cycle, and focused on server consolidation and infrastructure optimization. IT organizations that have successfully consolidated and optimized their virtual infrastructures face a unique set of virtualization management challenges. Server provisioning that used to take weeks can now be achieved in minutes, and results in increased virtualization adoption within the business. This increased adoption results in 'VM sprawl’ (the problem of uncontrolled workloads), increased provisioning and configuration errors, and the lack of a detailed audit trail – all of which significantly increase the risk of service downtime.

Windows Azure Series – Introduction to Windows Azure

Sat, 29 Jan 2011 06:00:00 EST

I’ve done a Windows Azure Series together with Mario Szpusta, Software Architect Evangelist at Microsoft Austria on Windows Azure.
