"Without my permission, this country could not move a leaf." SMEs in the United States before the Lord, as if the cloud computing service providers has become a dictator.
Jonathan. Bao Teer (JonathanBoutelle) staring in disbelief in front of the bill - please for your right to use the day before to pay $ 5,000, is inscribed Amazon Web Services (AmazonWebService). Difficult business start-ups everywhere, and now flying for no reason the bill, Bao Teer just saved up a little good mood vanished - 3 days ago, he was the founder of Slideshare as a company (a start-up) occurred in a large Web site accidents, in nine colleagues two days after a night of overtime, the problem was solved.
He decided to immediately investigate the bill originally. Wanted, a cloud computing service providers dominate the market rules, a chaotic sequence emerging cloud computing ecosystem.
"2012 years ago, the use of cloud computing, you may immediately be calculated." Forrester analyst to the nation's self-appointed managers of small and medium cutting-edge home warning.
This thesis point out the concept of cloud computing is currently in an embarrassing situation: noisy and frequent condition. September 15, the fourth Summer Davos Forum to focus on IT issues, "to maximize the potential of cloud computing," this issue. The forum was dished out the "gift theory" - "If the cloud to the IT departments of large enterprises has brought benefits, then for small and medium enterprises, it can be regarded as a gift of God."
Cloud computing is worship for SMEs in China, the United States came the cloud computing usage is probably not so optimistic. Although the start-up companies, with cloud computing means that you can start with the mouse on or off the power of thousands of servers. But if we learn and teach management as: "With great power comes greater responsibility." Start-up phase in the company, do not understand cloud computing, is likely to be immature cloud computing service providers "calculating."
Unexpected $ 5,000
In the United States, in order to reduce the servers, large storage equipment procurement and operation and maintenance costs, thousands of businesses and individuals are using the Amazon cloud service provider services, including the Eli Lilly pharmaceutical company, "New York Times "" Washington Post "and other famous enterprises. Amazon Web Services is a company specializing in remote computing power and storage services, cloud computing service providers. Users can pay-way, using the company's virtual servers and data storage space.
Bao Teer of Slideshare is no exception, this is the nature of a company's share presentations online community, known as the "presentation version of YouTube". Cloud computing is indeed more cost-effective than buying the server hardware, so they are using Amazon's cloud computing services. But all costs are paid, how Amazon has sent the bill? With three days ago that the accident, though?
Analysis report submitted under him understand the crux of the problem: to solve the last accident, forgot to stop the Hadoop analysis tasks. "Control of Hadoop, cloud computing is not easy to control." Bao Teer not help exclaiming.
Hadoop is a tool for cloud computing, it is in the cloud computing platform for users on a free expansion, reducing the number of the control server. Companies can develop distributed applications by Hadoop, the establishment of dozens to thousands of units, ranging from virtual server cluster. Slideshare is very valued in the start-up Hadoop, and even organized a team to quickly write some code based on Hadoop to analyze the company's user data. Although the need to lease a lot of the Amazon server, but the processing time is only one day.
But later, when the company began using more and more real data to complete the analysis of a client, it takes longer. Three days ago that accident, so Bao Teer realize that if you want to run faster, the only way is to increase the computing power per unit time. Therefore, Bao Teer immediately decided that day to lease calculator cloud services increased nearly four times the number from 20 to 75.
Problem arises here, $ 5,000 bill comes from these additional servers. After use, Amazon without any let Bao Teer restored to 20 server the size of tips and steps.
Slideshare experience to start-up experience is to use cloud computing: Amazon does not provide any tools to help users easily track expenses. If you want to use the power of cloud computing is good, then you need to keep observing spending, especially when you quickly expand and shrink with the size of the cloud server, make sure it did not exceed the company's budget.
High cloud storage
Has experienced an unexpected $ 5,000 bill, so Bao Teer more depressing thing happened - in the storage (AmazonS3) expenditure suddenly increased.
Slideshare as "PPT version of YouTube", a large number of documents per day need to use Amazon's cloud storage service provided. Slideshare users use the site to provide storage in the service, the appropriate amount of cloud storage is generally not volatile. How will suddenly increase storage spending it?
After several days of investigation, Bao Teer found in the use of cloud storage company failed to comply with specific rules. For example, some files can be deleted also retained; different types of files are placed in the same directory; some of the documents the company did not know where they came from, can not be deleted. These documents take up a lot of cloud storage space, the corresponding cost is exponentially increased.
Individual users is very easy to write code, but a team to write more than one dependent cloud storage program, it is easy to forget to delete some files. All cloud storage service, Amazon's cloud storage module - AmazonS3, can be seen as a large file system, they do not interfere with the user's data storage, but mechanically charged "storage rental."
Immature cloud service
Slideshare encountered in the use of cloud computing problems, many U.S. start-ups have encountered. Although cloud computing has indeed contributed in reducing costs, but the ability to provide services has been criticized.
Two years ago, Amazon's S3 and EC2 had shut down three hours, many business users are affected: missed sales opportunities, not been able to manage company information. Outages of cloud services, the quality is far from the negative impact of the introduction of a data recovery service can make up.
In addition to unknown to the downtime, cloud storage of data security is also being challenged.
In June, the cloud service provider AT & T exposed vulnerabilities, leaked more than one hundred thousand iPad user's e-mail address. Many users have directed their attacks at Apple, but the problem actually lies in the AT & T's cloud services. AT & T on the matter was solemnly apologize to the users.
These events put together a true "cloud world" - there is no hymn, we see only the risk of disorder.
In the absence of any institution can put forward before the cloud service standards, start-ups need to learn to help themselves. For example, cloud computing service provider for the status of a sudden stop, the best way is that they have consciously security testing to check whether the cloud computing service providers to quickly recover data. Is simple: send an email to the vendor to ask for your stored data, and checks them how long it takes to restore the data.
Each new technology in the early stage of development will have a lot of negative comments. For start-up companies, spend some time to understand cloud computing habits, learn to control it be possible to get the results you want. As Forrester analyst said, cloud computing is maturing in two to three years after the adoption of cloud computing will be a wise choice.
