Dynamics 365 solutions are hosted in the Azure cloud, which is supported by Microsoft. This means that Microsoft is responsible for maintaining the system, storing data and performing updates.
Comprehensive IT infrastructure maintenance and high reliability guaranteed by Microsoft
When choosing the Azure cloud, you don’t have to devote your attention to managing servers and IT infrastructure. For most companies, the decision to use the cloud in addition to saving time is reflected in financial benefits. Azure offer the maximum minimization of necessary expenditure on IT infrastructure. To access the Business Central system, all you need is a computer or a mobile device with an internet connection.
It is worth noting that the SaaS solution is more scalable. Actually, you can run another license at any time. At the same time, there is no need to organize additional computing power (in the SaaS model we buy licenses for a named user).
Microsoft provides high reliability by guaranteeing 99.9% availability. At the same time, in the event of a possible failure, you do not have to worry about data loss and backup, because Microsoft is responsible for maintaining the infrastructure.
It is good to know that Business Central users in the cloud usually receive an update earlier than people using the on-premise version of the system. Importantly, Microsoft is responsible for updates. Usually, the updates are automatic (of course, the user can decide when the update should take place).
The Microsoft Azure cloud is much more than just maintaining Business Central. By using Business Central in the SaaS version, the organization has access to many integrated services. For example Office 365, PowerBI (Business Intelligence), SharePoint, PowerApps and Machine Learning solutions.
Microsoft strongly recommends cloud solutions. Organizations around the world are also turning to the slogan “cloud first”. The use of Azure cloud has significant advantages. Savings in the purchase and maintenance of IT infrastructure, high scalability, high availability and really good security against data loss, automatic updates and flawless integration with other solutions maintained in the cloud are the benefits of implementation of the SaaS system or the transfer of an existing Dynamics 365 Business Central instance to clouds.
