Today cloud technology is becoming more widespread. But as with most novelties, many myths are associated with them. People sometimes find it difficult to understand how files, programs and infrastructure do not exist on a particular computer, but somewhere on the Internet. As a result, the new technology is perceived with caution by most users and companies.
Experts say that soon cloud technologies will get mass distribution, most sites will be located there, and all large companies will soon transfer their services to “clouds”.
In the meantime, there is no point in hurrying to introduce such technologies everywhere, but the benefits already begin to noticeably outweigh the negative factors. Myths about “clouds” are increasingly insolvent under the influence of new features of this service.
Cloud services are not safe.
In the clouds, you can get remote access to files. This means that this data can not be stolen from the local computer. The service agreement specifies the level of business security that the service provides. Do not think that clouds are 100% protected from hackers. Interest in these services is more, the more companies transfer their data there. There are interesting statistics – 98% of attacks are from outside agents, 4% of attacks are performed by employees themselves.
Cloud technologies – for large companies.
A regular Internet user believes that the clouds are created exclusively for business. In fact, any of us already use these services, without even thinking. For examples, you do not have to go far: Microsoft Office 365 or Dropbox, and who was not on the fancy Facebook and VKontakte? Since we know these tools, cloud technologies have already entered our life.
Cloud technologies do not make sense at all.
You can always select the system that will work within the specified limits and norms. At the same time, management will be simplified, but moving to the cloud will not entail structural changes in the business. It is just necessary to outline your needs at the very beginning of the process. Then there will be a system within the cloud that will work correctly and maintain the necessary balance.
Cloud technology is needed only to save money.
Money is really an important factor, but it is not the only one that determines the benefits of such a service. It is very important for business in terms of scalability, remote access from various devices and reliability.
Because of the transition to the cloud, the ability to use important applications will disappear.
Actually, this will not happen if we outline our goals and the necessary tools at the beginning of the transition to the cloud. Knowing what is required by the client, the developers of cloud services can create such a system, which will work in accordance with the tasks set. So to protect yourself from future difficulties and problems with the functionality is easy – you need to think about this in advance.
It’s better to use a public cloud.
This model is very simple and common. In it, users pay for what they use. However, this is not the best option, if you suddenly need to increase some resources. So in this case, a more profitable, and most importantly convenient, option is a private cloud. Depending on the fundamental requirements of business, this is the option that most often looks preferable.
The cloud is the same as running programs and network services in a virtual machine.
The presence of a virtual machine on the server does not indicate a running cloud computing environment. In fact, this is the first step to using them, but it’s too early to say about full ownership of all the benefits. To provide the whole range of services that can be compared to cloud services, a virtual machine must be able to rapidly increase or reduce its computing resources, as well as storage.
Before moving to the cloud, it’s best to first try out virtual solutions.
Virtualization can really be justified for using existing resources. However, in the long run, this will simply be a waste of time, if the strategic task of moving to the cloud is worthwhile. For many companies, the transition to the cloud can become a really painful event, but you need to evaluate the final pluses and minuses and do not delay with the decision, using temporary solutions like virtualization.
Cloud services by default guarantee security.
The level of security is the same for everyone and is not required. It is necessary to understand what is the most critical for business and pay special attention to the protection of personal data. It is worth assessing your security needs, analyze the risks. Then the very same safe architecture will be born, which was required in the end. Do not think that the service will take care of all these questions, it is possible that the matter will be limited to recommendations.
Cloud applications work around the clock, every day of the year.
It is too early to say that cloud technologies give constant and round-the-clock access. There is still the possibility of downtime, even if the service provider claims the opposite. That is why it is especially important to read all the terms of the proposed service contract. If access is so critical, then it is possible to supplement the agreement with the lawyer, outlining all the possible risks of failures and their impact on the lost profit.
Because of the cloud technology, performance drops.
This can not be asserted, since business owners gain access to both the huge storage and the management of their enterprise. And instant scalability in most cases only speeds up the work.
Cloud services do not give new jobs.
Such giants as Google and Amazon have a constant need for specialists who understand the specifics of cloud solutions. They will find themselves in them administrators of networks and databases, information and system analysts, software developers and web designers.
The cloud is a temporary and fashionable fad.
Large companies see interesting prospects in this direction. So, Microsoft allocates annually 8,6 billion dollars for new researches. 90% of all this impressive amount is spent specifically on improving cloud technologies, ensuring their security.
The organization will only be able to work with one vendor and when data is transferred to the cloud, control over them will be lost.
The main task when using such services is providing flexibility. Applications can well call other applications in different cloud services, and data can be stored anywhere, including inside the corporate network. You just need to give access to them for cloud-based applications. No cloud service provider will provide such a service, which would be completely independent of the user’s environment. The best solutions are those that combine local and external placements. And regardless of the chosen service provider, the most important thing is the security of your data. So it is worth to abandon such a cloud, which initially will consider the information of the enterprise as its property.
You can experience all the advantages of cloud technologies by creating on your own equipment a “private” cloud.
As mentioned above – private clouds can really give the company benefits. After all, the maximum control over all components – equipment, programs and even taking into account downtime, remains. However, a private, local private cloud will continue to be a string in capital expenditures. This is the important difference from those assets that are held by third-party service providers. To realize all the benefits of a private cloud, the savings from using its infrastructure for serving should exceed spending on creating the cloud itself.There is also such an option that the equipment will be serviced by the service provider. So capital costs will flow into operational ones.
In order to fully experience all the “delights” of cloud service, the company must transfer all its applications there.
Again, we can not transfer the entire data center to the cloud. And the providers of cloud services themselves do not recommend doing this. First, you need to identify those applications, the transfer of which into the cloud will give additional benefits the fastest. Then it is worthwhile to determine what uses intensively resources in short intervals throughout the month, and for the rest of the time is idle, to identify applications with a constant use of the average amount of resources and to determine the periods of their highest activity. These applications are also suitable for transfer to the cloud, as its resources can then be scaled.
There is only one kind of cloud.
Actually, there are several types. For example, a client cloud is a private cloud with a local location. Another option would be a “cloud partner”, this is also a private cloud. A “public cloud” is a network of application services and web services with poor communication. It is this version of cloud computing that is discussed today most often.
