It's time to think about cloud computing.

InformationWeek recently made a survey of cloud computing, although 65% said they would not move their IT applications to cloud mode, and the authors still believe that cloud computing is far from over. Remote work, laptops, smartphones, and the ubiquity of devices connected to the Internet have made many people have 2 to 3 different devices, and synchronizing data between these devices is frustrating for many people who want apps and data to be readily available.

Cloud computing vendors are making a perfect storm about SAAS (software-as-a-service), Grid computing, virtualization, hosting and outsourcing, and the ubiquity of broadband and 3G connectivity also gives people the ability to access their apps anytime, anywhere.

Among those surveyed, 23% were skeptical about cloud computing, which they thought was a hype and a new bottle of old wine. Their position can be understood, change is always difficult, but now the mobile interconnected environment needs a new application distribution mode. Cloud computing goes to the forefront of the market, and no organization can ignore it or ignore it. A reader said that I believe that enterprises in the SaaS mode to buy CPU time, data storage, applications, like enterprises to buy water and electricity, purchase cleaning services as natural, the budget is a good thing for the enterprise.

The survey shows that the business applications that most expect to be implemented through cloud computing in two years include systems that run through the Internet, such as CRM, ERP, and then the CPU time that is provided by the cloud provider, and the storage space runs its own program (such as Amazon's cloud computing Service-translator)

About migrating some services to cloud computing, surveys show that applications that are most likely to go first, such as storage space, archiving, and disaster recovery, are well understood because they are the least valued in the enterprise, and cloud computing environments provide good fault-tolerant and disaster-recovery capabilities without high input.

65% said that meeting business needs quickly was the most important driver of cloud computing. The biggest challenge of IT environment construction is to provide abundant resources, have a customer, calculate, discover need to deploy more than 200 servers, but these server resources utilization only 9%, this is a great waste. Using cloud computing, there is no need to design such a large amount of redundancy, you can buy on demand, you can significantly reduce costs.

Although 77% of people said that the biggest benefit of outsourcing is worry, but another data show that the real reason to save money, if both save money, and worry nature is the best.

Cloud computing remains to be done

Cloud computing is not just that there is no problem, nor will it come immediately. In fact, 2008 has a lot to do with cloud computing shadow, Google's Gmail and application services down machine, Amazon's S3 8 hours, these accidents if frequent, will frustrate many people's confidence. Large cloud computing providers need to provide a stable service. and WAN expenses. How much bandwidth you need to access cloud services depends on different application requirements, but network failures can also be an important potential problem.

Prior to the purchase of cloud computing services, it is important that the SLA (Service-level Agreements) service agreement is signed with the service provider, and that the success of cloud computing is largely determined by the quality of service and the reliability of the service.
