Tune into: a cloud mindset One of the tenets of the cloud religion is that it should be possible – through the use of intelligent software – to build reliable systems on top of unreliable hardware. Just like you can build reliable and affordable storage systems using RAID (Redundant Arrays of Inexpensive Disks). One of the largest cloud providers even evangelizes to its application development customers that they should assume that “everything that can go wrong, will go wrong”.  In fact their SLA only kicks in after a minimum of two zones becomes unavailable. Quite a surprising but none the less a typical cloud approach. Nowadays most of the large cloud providers buy very reliable hardware. When running several hundred thousands of servers a failure rate of 1 PPM versus 2 PPM (parts per million) makes quite a difference. And using too cheap memory chips can cause ... (more)

Cloud Predictions Beyond 2011 - Part 1: Consumer Services Rule

In the past weeks we launched directly from the season of cloud events into what SYS-CON calls the Annual Predictions Bonanza. Gartner released its predictions on December 1 leading with "critical infrastructure will be disrupted by online sabotage."  At CIO magazine Bernard Golden gave two  interesting points of view, one for vendors and one for users, and even CA Technologies offered insights into the changes we expect in 2011, including how "security will shift from being perceived as a cloud inhibitor to becoming a cloud enabler." So, what happens after 2011?  In a few upcomi... (more)

Cloud Computing Becomes Cool Computing?

In December InformationWeek’s Bob Evans started a contest asking their readership to come up with a better name for “Cloud Computing”. Reason was that the CEO’s of both HP and IBM recently expressed some discontent with the current name. Something about “Cloudy not being clear enough”. Not clear enough for what, for justifying really large invoices? And then we are not even mentioning Oracle’s CEO, who has been on a contra-Cloud quest for ages. The overwhelming majority of the 500 names the contestants submitted were acronyms, which make you wonder whether IT is truly beyond salv... (more)

Shedding Light on Cloud Computing - A Free Primer

Cloud Computing is the most discussed IT innovation of recent times. This Primer provides a structured overview of what Cloud Computing is and what the potential benefits and risks are. In addition it explores how Cloud Computing will impact IT management and IT's role in the organization as a service provider. It also looks at the risks of Cloud Computing. Risk is consistently cited by CIOs and CFOs as the largest obstacle of cloud computing for their organizations. In this primer we consider the risks in areas such as availability, privacy and regulatory compliance. The bookle... (more)

Vendor Lock-in and Cloud Computing

IT vendor lock-in is as old as the IT industry itself. Some may even argue that lock-in is unavoidable when using any IT solution, regardless of whether we use it “on premise” or “as a service”. To determine whether this is the case, we examine traditional lock-in and the to-be-expected impact of cloud computing. Vendor lock-in is seen as one of the potential drawbacks of cloud computing. One of Gartner’s research analysts recently published a scenario where lock-in and standards even surpass security as the biggest objection to cloud computing. Despite efforts like Open Systems...
