Rapid growth and a variety of cloud services are impressive. More than 94% of world organizations use cloud storages. Besides, it is projected that there will be more growth in this technology. Reasons are clear: less consumption of organization resources, accessibility from any device that has an internet connection, and… Yup, that's it, actually. Unfortunately, these advantages equal dependency on the cloud service provider.

Convenient work in a cloud requires a reliable internet connection available in big cities mostly. For example, one premise does not have such issues, but when any crash or failure occurs on the cloud provider's side, you lose access to data for an indefinite amount of time. All you can do is wait for the service to restore. A similar situation happened with Slack users on July 27, 2019, when access to the service for message exchange was lost for 40 minutes.

The fact that companies spend less money when using cloud services is true. But on the other hand, service changes and transforms regularly, and one must either adapt quickly or hire a specialist (which contradicts the idea of resource savings). Besides, it is impossible to add new features or modify the existing ones.

Notice, that a user trusts his data to a cloud service stored on servers that he does not know anything about: where are they located? Who has access and permission to manage them? A provider guarantees and releases reports about the work done, but a user can't check it to make sure that it is true.

Do not forget about the “authentication attack”. Such an attack type frequently has seen in cases of account data breaches. Hackers are always around learning different services and software. For them, any change in security measures is a new challenge. It does not matter how frequently developers improve the structure of the security, there is always a bored internet warrior ready to show his strength.

In the table below we show that installing your own server is not as scary as it seems. And those distinctive features of cloud services that were considered as an advantage over self-hosted software are not their privilege anymore. For example, let's take a set of features that makes people use cloud hosting and messenger with their own server — MyChat, version 8.5.
