Cloud technologies

Cloud technologies are gaining popularity today. As a result, the new technology is perceived with caution by most users and companies.

Experts say that soon cloud technologies will become widespread, most sites will be located there, and all large companies will soon transfer their services to the "clouds".

In the meantime, it is not worth rushing to introduce such technologies everywhere, but the benefits are already beginning to noticeably outweigh the negative factors. The myths about "clouds" are increasingly untenable under the influence of new features of this service.

Cloud services are insecure. In the clouds, you can access files remotely. This means that this data cannot be stolen from a local computer. The service agreement specifies the level of business security that the service provides. Don't think that clouds are 100% safe from hackers. The more companies move their data there, the more interest in these services. There are interesting statistics - 98% of attacks are carried out by external agents, another 4% of attacks are carried out by company employees themselves.

Cloud technologies for large companies. The average Internet user thinks that clouds are created exclusively for business. In fact, any of us already uses these services without even thinking. You don't have to go far for examples - it's Microsoft Office 365 or Dropbox, but who is on the sidelines of the fashionable Facebook and VKontakte? Since these tools are familiar to us, then cloud technologies have already entered our lives.

Cloud technologies don't make sense at all. You can always choose the system that will work within the given boundaries and norms. At the same time, management will be simplified, while the transition to the cloud will not entail structural changes in the work of the business. You just need to outline your needs at the very beginning of the process. Then, within the framework of the cloud, that system will be created that will work correctly and maintain the necessary balance.

Cloud technologies are needed solely to save money. Money is a really 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 accessibility from various devices, and reliability.

Moving to the cloud will remove the ability to use important apps. In fact, this will not happen if you outline your goals and the necessary tools at the stages of the transition to the cloud. Knowing what the client needs, cloud developers can create a system that will work in accordance with the tasks. So it is not difficult to protect yourself from future difficulties and problems with functionality - you need to think about it in advance.

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 the business, this is the preferred option most often.

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 is too early to talk about full ownership of all the benefits. To provide the entire range of services that can be compared with cloud services, a virtual machine must be able to quickly increase or decrease its computing resources, as well as storage.

Before moving to the cloud, it's best to try virtual solutions first. Virtualization may indeed be justified to leverage existing resources. Ultimately, however, it will simply be a waste of time if the strategic goal of moving to the cloud is ahead. For many companies, the transition to the cloud can be really painful, but you need to assess the ultimate pros and cons and not delay the decision, using temporary solutions like virtualization.

Cloud services are secure by default. The same level of security for all and is not required. It is necessary to understand what is the most critical for the business and pay special attention to the protection of this data. It is worth assessing your security needs, analyzing the risks. Then the very safe architecture, which was required in the end, will be born. Do not think that the service will take care of all these issues; it is quite possible that the matter will be limited to recommendations.

Cloud applications work around the clock, every day of the year. It is still too early to say that cloud technologies provide 24/7 access. The possibility of downtime is still possible, even if the service provider claims otherwise. That is why it is especially important to read all the terms of the proposed service agreement. If access is so critical, then you can supplement the agreement with a lawyer, outlining all the possible risks of failures and their impact on lost profits.

Due to cloud technologies, performance drops. This cannot be said, since business owners have access to both a huge storage facility and the management of their enterprise. And instant scalability in most cases only makes things faster.

Cloud services do not provide new jobs. Giants such as Google and Amazon have a constant need for experts who understand the specifics of cloud solutions. Administrators of networks and databases, information and system analysts, software developers and web designers will find themselves in them.

The cloud is a temporary and fashionable fad. Large companies see interesting prospects in this direction. So, Microsoft allocates $ 8.6 billion annually for new research. 90% of this impressive amount is spent on improving cloud technologies and ensuring their security.

The organization will be able to work with only one supplier and when data is transferred to the cloud, control over it will be lost. The main challenge when using such services is to provide flexibility. Applications may well call other applications in different cloud services, and data in general can be stored anywhere, including within the corporate network. You just need to give access to them for cloud applications. No cloud service provider will provide a service that is 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 abandoning such a cloud, which will initially consider the enterprise information as its own.

You can experience all the benefits of cloud technologies by creating a "private" cloud on your own hardware. As stated above, private clouds can really bring benefits to a company. After all, you retain maximum control over all components - equipment, programs and even accounting for downtime. However, own, on-premises private cloud will continue to be a line in capital expenditures. This is an important difference from those assets held by third-party service providers. To realize all the benefits of a private cloud, the savings from using the infrastructure that serves it must exceed the cost of creating the cloud itself. There is also such an option that the equipment will be serviced by a service provider. So capital costs will flow into operating costs.

To fully experience all the "delights" of a cloud service, a company must move all its applications there. Again, moving your entire data center to the clouds is simply not possible. And cloud providers themselves do not recommend doing this. The first step is to identify the applications that move to the cloud will provide the fastest added value. Then it is worth identifying what is using intensive resources in short intervals throughout the month, and idle the rest of the time, identifying applications with a constant use of average resources and identifying the periods of their highest activity. These applications are also suitable for migration to the cloud, as its resources can then be scaled.

There is only one kind of cloud. In fact, there are several types of them. For example, a customer's cloud is a private cloud on premises. Another option would be “partner cloud”, which is also a private cloud. And the "public cloud" is a network of poorly connected application and web services. It is this version of cloud computing that is most often discussed today.
