CloudCamp is an unconference where early adopters of Cloud Computing technologies exchange ideas. With the rapid change occurring in the industry, we need a place we can meet to share our experiences, challenges and solutions. At CloudCamp, you are encouraged you to share your thoughts...
John M. Willis has pointed me to a new research paper by Lamia Youseff (University of California, Santa Barbara) Maria Butrico, Dilma Da Silva (IBM T.J. Watson Research Center), have created titled “Toward a Unified Ontology of Cloud Computing.” The paper lays out a proposed Cloud Comp...
Interesting release from Google today, they've released a hybrid OpenID OAuth Extension which they describe as a mechanism to combine an OpenID authentication request with the approval of an OAuth request token. In case you're not familiar with oAuth, it is an open protocol, initiated ...
The core ECP data module has many new features as well as many bug fixes. Several subtle but detrimental object retrieval issues have been resolved. This alone fixed several issues that were thought to be GUI related in previous ECP versions. The new features include added flexibility ...
Great post by Benjamin Black the current VP, Research at Joyent and former manager of Website Engineering at Amazon.com. In his post he gives an interesting insight to how Amazon Ec2 came to be. Black outlines a backstory which takes place in early 2004, "i was told jeff was interested...
I love reading stupid headlines from stupid articles, I won't point specifically to them because we've all read them. In particular I've read a few lately that have pointed out that "cloud computing" isn't ready for primetime, it's too new, it's only for early adopters, trailblazers an...
The CCIF and it's members have recently focused on creating a common cloud taxonomy and ontology. I find it's starting to sound a lot like semantics, Cloud Semantics. We are in a sense defining what cloud computing is by describin...
Cisco is planning to start building servers. To be precise, servers equipped with virtualization software. A fascinating article in the New York Times expresses some surprise at this move, but it seems terribly obvious now that the news is out. After all, there is already a move afoot ...
Cisco is getting into the server business, says NYTimes.com. One could argue that the writing was on the wall when Cisco announced their Nexus virtual switch platform complete with deep VMware networking integration, but now there are few doubts that Cisco has clear designs on owning a...
When thinking about what Cloud Interoperability truly means, for me it's all about the API. There is much talk of ID / Authentication, storage, networking, system management and so forth. The one problem that all these various aspects share is that point of programmatic access / contro...
Storage within the cloud is meaningless without a measurable level of performance that it can be compared against. Since there are no established benchmarks that determine performance of storage within a cloud infrastructure, it is reasonable to apply tiering metrics to storage based o...
To the extent that organizations use governance to harness the richness of cloud environments, they will be able to supercharge their SOA initiatives while radically improving scalability and cost-effectiveness. Unfortunately, the cloud arena may continue to evolve so fast over the nex...
‘The Big Switch’ elaborates on Carr’s earlier comparison of the Electricity Generating industry, at the start of the last century, and today’s Computing industry. He argues that such a move, with its massive economies of scale, was an economic necessity at the time and that today’s tec...
What are the benefits from using Cloud Computing services or platforms? Cost efficiency, shorter innovation cycles and scalability are frequently mentioned promises. However, the value proposition of Cloud Computing obviously depends on the corresponding business scenario. You cannot p...
Cloudcenters provide the same kinds of tools that all datacenter and server operators are already accustomed to, but with all the traditional advantages of cloud (i.e. self-service, pay-as-you-go, and scalability). Instead of creating completely new paradigms, cloudcenters are a method...
Cloud computing figures prominently in recently released Gartner report entitled "CIO New Year’s Resolutions, 2009." Gartner’s overall advice to the CIO is to do what is necessary to survive in ‘09, but to be sure to also invest in the future by building and preparing for what lies bey...
Am I the only one who has trouble understanding Cloud Computing? Is Instant Messenger considered cloud computing? Is my company's enterprise deployment of XenApp on XenServer considered Cloud Computing? Is the iTunes store considered Cloud Computing? Why is Cloud Computing so hard to ...
Finally, after years of providing just a command line interface to their web services, Amazon has released a web based management console. Has it been worth the wait? In a nutshell, yes. We knew this day was coming, and 8th of January was that day. Built using Yahoo's YUI framework, us...
Are humans really necessary for maintaining SLAs? In today's cloud computing deployments, especially with systems like Amazon's EC2, the users' application is responsible for both measuring and taking action on application performance issues. This complicates deployment and coding, as ...
In the next few years the a key opportunity for the emerging cloud industry will be on defining a federated cloud ecosystem by connecting multiple cloud computing providers using an agreeing upon standard or interface. There are a number of organizations looking into solving the proble...
Instead of creating a less complex environment, in many cases virtualization has made it more complex. Many business- and mission-critical applications are just not right for a hypervisor. Other software applications won't even support hypervisors even today.
With the advent of Cloud Computing and the general resurgence of computing grids, data storage has been taken for granted. However, as cloud computing’s storage and access demands continue to grow, the need for an optimized storage layer and hardware accompaniment become even more crit...
What is going to happen to technology companies in 2009? If Democrats are good for technology what companies are Republicans good for - that is, what is going to happen to non-technology companies in 2009? Here's a look at some charts that correspond to leadership in the White House an...
As the year winds down, I thought it would be a good time to think about New Year’s resolutions. Let’s face it. A lot of us come up with New Year’s Resolutions each year. Sometimes we see them through, and sometimes we don’t. I don’t think it would be very interesting to blog about my ...
There is a myth going around about virtualization and cloud computing. It’s expressed in a variety of ways, but the takeaway is always the same: “Public clouds are big virtual server clouds.” Sounds good, but untrue once you look under the covers. For good reason, since virtualization ...
Comparisons between Scale-Out and Enterprise clouds, while sometimes tempting (especially in the Google vs. Microsoft case), are rather useless. They serve different purposes, often for completely different audiences, and enterprise IT organizations would do better to focus their effor...
I recently successfully imported a physical line-of-business (LOB) server into Hyper-V. In other words, replacing a physical server with a virtual machine. That migration is a procedure that lots of businesses, small and large, will be encountering for reasons similar to my own.
If a user can use distant computers to process local jobs, s/he is working with cloud computing. (Cloud computering?) As we consider the various definitions for “cloud computing,” it may be useful to consider it as the next logical step in moving from the cave to the hive mind.
Cloud computing isn’t about doing anything new, instead it’s about applications that run in the web rather than your desktop. Some technology experts define CLOUD as follows: Common, Location-independent, Online Utility provisioned on-Demand.
I see this whole cloud computing movement as nothing more than a reincarnation of the classic mainframe client-server model. People want painless access to their data and applications from wherever they are, from whatever electronic gizmo they happen to be using.
IaaS standards will enable a market place in which workloads can be moved from cloud to cloud according to price, capacity, and feature criteria. A few companies are jockeying for the pole position in the race to provide the arbitrage for this meta cloud.
There have been multiple white papers and articles written by analysts - Is Cloud Computing Ready for the Enterprise? The question is asked so many times now - Is Cloud Computing ready for the enterprise? So, I have to ask - Is the enterprise ready for Cloud Computing? I’ll start this...
In the last couple of weeks of 2008, IT departments and CIOs need to think carefully about the cloud and how it can be used within their organizations - ahead of the business units. Develop, distribute and educate staff on policies around Information Protection and data loss prevention...
Cloud computing promises to change much of how we as developers, designers, and architects currently design and build web applications. For one, concurrency is big issue that need to be addressed if the apps of the next decade are going to scale on this cloud infrastructure.
Enterprises normally move slowly to new technologies but when the price advantage is close to 10x, enterprise decision makers can and will move more quickly. The weak economy provides yet a stronger push. It won’t happen at once and it won’t happen instantly but I’m convinced that in 7...
Once we cut through the cloud-hype and start looking at the practicalities of implementing things like workload portability, I think the lessons of the past will re-assert themselves, this time with things like security and L4-7 services.
Although cloud computing vendors are not explicitly trying to lock-in customers to their platform, the fact is that today if a customer has heavily invested in either platform then there isn't a straightforward way for customers to extricate themselves from the platform and switch to a...
Yesterday I was hanging out at the Microsoft office in Los Angeles for an “Architecture Council” meeting on the new Cloud Computing platform. We discussed what Microsoft considers cloud computing, the trade-offs between “on-premises” and cloud appsYou can find the slide materials on th...
Steve Bobrowski wrote an interesting whitepaper about the Force.com Multitenant Architecture. He describes multitenancy as a design approache to improve the manageability of SaaS applications and metadata-driven architecture as the choice to implement multitenancy.
In most discussions about scalability, we often approach the topic as a pure technical/architecture challenge, and ignore cost issues. The problem is that when we truly scale our application, and want to benefit from economies of scale, we're going to end up with scale limitations, not...
