Cloud Computing's eight major changes to network management

People have a variety of attitudes towards cloud computing, from the lack of interest to enthusiastic acceptance and learning, the cloud technology as a technical area of the Gospel, what kind of people have.

Those who have no interest in cloud computing think of cloud computing as a copy of the "Back to the Future" model of computing, where the old car goes back to the "time-sharing" heyday of the 70, renting out surplus computing resources remotely. At that time, customers could buy computer CPU time, networking time and disk space, and pay extra for the use of certain special software such as Model 204 (High Performance database management system, known as Bitmap indexing technology) (model 204 has nearly 40 years of commercial history). These people think that there is no fundamental change in the technical challenge compared with the original, and the distribution calculation is more fully applied. And the benefits that users derive from this computing model have not changed. The users of time-sharing systems are independent of the data centers hosting a large number of high-performance computers, and they are able to access considerable resources with little cost.

Another group of people with a completely different attitude to cloud computing, also known as Cloudista, is the Gospel of cloud computing as a web technology, thinking that the technology of the past belongs to the past, and that the cloud computing technology is much different from the past. They insist that, compared with the past, the current network bandwidth has expanded a lot, customers in charge of their own network, personal computers or mobile devices can handle a considerable amount of local operations. Moreover, the user community is quite complex. In the 70 's, users who were able to use time-sharing systems were government agencies or fairly large, capital enterprises, with a total of thousands of. Instead, a typical representative of a remote mainframe,-itunes, has up to 200 million users in 2011. One-fourth of adults in the United States are using mobile apps, many of which rely on cloud services. Cloudista that the cost of cloud computing has created economies of scale and operational performance, unimaginable in the 70 's.

The NIST Cloud Computing project says: "The cloud computing model promises tremendous flexibility for it and helps businesses save a lot of costs." "In addition, NIST has the" fast wan "as the top three technologies needed for cloud computing (the remaining two technologies are fast servers and High-performance virtualized standard hardware devices). NIST's point of view represents a large number of people, but also indirectly in line with the future development of network engineering goals.

Apple recently released its icloud cloud service, and Apple, like Google's Chromebook, believes that sooner or later, companies will be on the big ship of cloud computing. And now the cloud is only facing some long-standing controversy, so I listed below the network technician more interested or more concerned about the trend.

#1 WAN Feature Settings

Sooner or later there will be some employees in the enterprise, and some departments may want to try to connect to one of these or the other cloud computing services that appear on the market. The network staff of the enterprise is more concerned about the WAN line and the setup problem than ever, and this is not just the network bandwidth.

#2 and location-independent computation

Position Independent computing is not a new concept, but millions of employees are now able to experience the technology developed according to this concept. Naturally, employees want the software they buy to be able to work anywhere, anytime. For large multinational companies, this application also faces the corresponding challenges.

#3规模和可靠性预期增强

The concept of synchronizing content has been on the show for a long time. About 20 years ago this concept appeared on the market as part of personal information Management (PIM) software. In cloud technology, the scale and expected effects of this concept have increased dramatically. Synchronized content is no longer limited to hundreds of of lines of text content (such as a contact book), and even terabytes of data can be reliably synchronized. The increased uptime and enhancements of cloud computing services can lead to problems with local resource management and even to the careers of some IT professionals.

#4 point of failure increased

Network upgrades or topology changes to apply cloud services may result in more points of failure, and the number of users that may be affected by each failure point may increase.

#5 Disaster recovery plan and risk assessment need to be redefined

Reliance on cloud computing will lead to an outdated enterprise disaster recovery plan, which must be revised again, and the risk assessment of the enterprise will change. Some risk levels may be reduced, such as a cloud backup of some of the enterprise data to achieve a certain level of offline security, which was not easy to implement within the enterprise. In addition, the power outage caused by a business or even the entire enterprise business stop, also may not be considered completely.

#6 Synchronization is important

The file-level synchronization capabilities provided by icloud are relatively simple and common functionality available to all cloud service providers, while some synchronization features are not so simple. Synchronization failure can severely damage the integrity of the backup, and the resulting error may take several days to be discovered, or even months later.

#7 consistency of upgrades and migrations

While some cloud service providers may give customers the right to some configuration management services, most service providers do not provide this service. Therefore, the internal project coordination, test plan and training budget to achieve the plan, to avoid the impact of new services on the business.

Impact of #8 balance sheet

In the company's financial status, different leasing services have different attributes, and different companies have different requirements for leasing costs. It is not understood by all leaders that the cost of purchasing it fixed assets is used to lease IT services.

Price

Cloudista think they are pushing for a computing model that does not require too much management, but this pattern can also bring other changes to the IT industry, where it practitioners need to confront and solve problems that are completely different from the past. Network administrators may have to focus more than ever on problems outside the enterprise, such as security and reliability, rather than just focusing on the internal problems of the corporate network, which takes as much energy as ever.
