Cloud Computing: the drawbacks and unavowable secrets of the cloud

Are you really familiar with Cloud Computing? Discover the little-known “secrets” of this technology, which it is best to know before you get started…

The Cloud is becoming more and more popular with companies and individuals. The different types of Cloud services are being adopted massively, and industry giants such as Amazon Web Services or Microsoft Azure are experiencing explosive growth.

However, the intricacies of the cloud remain unknown or misunderstood by a majority of users. Discover the “secrets” of the Cloud that you should know in order to decide whether or not to rely on this technology…

To know more about it

The data stored on the Cloud no longer belongs to you completely

The data you create belongs to you. However, if you store it in the cloud, the vendor you are turning to takes control of it.

You therefore trust the supplier to ensure that it maintains its Data Centers and your servers, that they comply with the laws in force, and that they are physically and virtually secure.

It is therefore important to Read the conditions of use and study the measures taken. safety and compliance issues before deciding whether or not to adopt a service. It may be appropriate to retain a lawyer to assist you in this regard.

The Public Cloud does not always save money

One of the advantages of the Cloud is that it can save money. However, this is not always the case.

For example, if you have already invested in an internal infrastructure, the Public Cloud may represent an unnecessary expense. It is therefore important to carefully weigh the advantages and disadvantages.

The Cloud makes you dependent on the internet connection

To use Cloud Computing, you must be connected to the internet at all times. This is obvious, but it can be a real constraint for your company if it is not sufficiently anticipated.

Your network must allow you to transfer files to the Cloud and retrieve them. It must also allow you to use virtual machines, even if you opt for IaaS (Infrastructure as a Service)..

If you lose your connection to the network due to a power outage or stormFor example, you may therefore be temporarily paralysed in your business. Cloud providers, on the other hand, guarantee service level agreements that require them to be available 95% of the time.

Features may be limited

The Cloud providers are not all the same.. Some offer limited bandwidth, limited storage space or poor accessibility.

A lot of SaaS are offered free of chargebut then you have to pay for additional space or optional features.

In fact, you need to be sure that you will be able to finance your changing needs as your business evolves. You must take into account this criterion by choosing your cloud provider.

The Cloud is not safe from hackers.

Some Cloud services may have been successfully targeted by hackers in recent months. However, the suppliers ensured they were invulnerable.

If your cloud service is hacked, your company’s sensitive data or your clients may end up exposed. It would be a disaster in terms of image and cyber security.

There is also a risk of data leakage in the event of a service configuration error. Many companies have fallen victim to this with ElasticSearch, even some of the largest.

You can’t solve technical problems on your own

In case of technical problems, you won’t be able to fix it internally. You will need to call the Cloud provider’s technical support.

Gold, some suppliers are not available 24/7. It is therefore preferable to choose a supplier offering this advantage.

Some Cloud providers may go bankrupt

Cloud leaders such as Amazon, Google and Microsoft look set for a bright future. However.., smaller suppliers are not necessarily successful.

Some are forced out of businessincluding among the pioneers of the industry. In addition to too few users, these companies may be faced with too high a burden.

This is the case if they pay for their own data centers… and have developed their services from scratch, while newer providers are turning to IaaS and PaaS. The new generation of providers has lower costs, and that’s what allows them to take the place of the old ones.

Gold, if your cloud provider goes bankruptyour data could be lost forever. Make sure you choose your provider carefully, and make sure you have a copy of your most valuable data stored on site.

An error in strategy can be paid for at full price.

By wanting to enable their company to adopt the Cloud, many IT managers have made mistakes which they paid dearly for.

If the Cloud is costing your business money, it is you may be dismissed accordingly. Wanting to make the transition to the Cloud can therefore be harmful.

The Cloud never forgets

All Cloud services offer you to back up your data, and to replicate it so that you can restore it in the event of a failure or incident. To do so, all users’ data is continuously updated.

Replication is optimized for maximum performance and minimum latency. However, it is almost impossible to optimize also the service to facilitate the removal of old files.

In fact, even when you delete a record, this deletion is not extended to all older versions stored on the system. The record or file seems to have disappeared, but this is not really the case. As a result, the Cloud never really forgets…

You will need a Data Steward to use the Cloud.

If you store your data in the cloud, you’ll need a data steward. . He is not a system administrator, but rather a business analyst.

He must be able to determine which data should be stored or not on the Cloud in order to avoid compliance issues. It must also understand the meaning of the data and prioritize it.

Sound role is also to monitor the import and flow of data between systems, ensuring their quality. The Data Steward will also have to develop adequate procedures for backups, record mergers or relationship building.

Finally, it will have to validate the results of the reports by ensuring that the right variables are used for filtering and grouping. Typically, this will be a part-time position for a person already employed by the company

The Cloud must be managed like a computer system since it replaces it.

Many companies make the mistake of thinking that the Cloud makes it possible to eliminate the need for IT. However, to enjoy the same capabilities and efficiency as a computer system, it is necessary to manage the Cloud as a computer system.

This is the case if you want mash-ups, custom code or the ability to drag objects from items from the desktop or if you want to integrate other internal or external data sources.

The same is true if executives want reports and dashboards. But to take advantage of such features, it is the need for an architect and a general contractor to work together.

Unfortunately, the main targets of Cloud vendorsThe majority of people, whether they are small businesses or departments of large companies, will rarely hear it from this ear. Large companies, on the other hand, know that it takes time and discipline to fully exploit the Cloud.
