Microsoft Certified It Professional
The joint work within many companies relies on collaborative software solutions that allow centralized management of emails, appointments, contacts and tasks. Among these solutions is the Exchange server, made available by Microsoft for Windows-based systems. microsoft certified it professional Launched in two editions differentiated by the spectrum of functions available to them, the installation of Microsoft Exchange requires the purchase of a license that allows its use as a solution in the cloud or as software on premises, that is, it can be hosted in the company's IT infrastructure. In this article we offer an overview of the features offered by Microsoft Exchange, we highlight some of its main features and guide you in making decisions regarding the most appropriate use model for your needs.
The Microsoft Exchange server can be used as software as a service (SaaS) or as a licensed installation on your own server.
Installation on premises : this model refers to the integration of software into the company's IT infrastructure. To do this, a license is required that authorizes the installation on the hardware itself and a client access license (Client Access Licenses, CAL). This license allows a device to be made available to several users, as well as to authorize a specific user to access the Exchange server through several devices. Here it must be borne in mind that such client access license (CAL) does not include the use rights for the client software that is necessary (Outlook, etc.).
Exchange online : in the framework of the Office 365 online service, Microsoft also offers this software as a cloud solution. This means that the Exchange server is not managed in the company's data centers, but is hosted in the Microsoft-owned cloud. In order to use its functions you need a user subscription (User Subscription Licenseor USL), which authorizes the use of the Exchange server as SaaS and also allows parallel management in the own data center, thus leaving open the possibility of hybrid hosting.
Hosted Exchange Server : This last option requires an external provider, which, as a rule, consists of a web hosting provider that has the necessary Microsoft licenses for the commissioning of Exchange. This option allows end users to enjoy the functions of the Exchange server with different rates adjusted to their needs.
Choosing the most appropriate model depends, in the first instance, on the size of the company. The solutions in the cloud are designed for medium-sized companies that do not usually have the means or personnel to guarantee the installation and maintenance of a professional IT infrastructure. Taking fundamental data protection measures and carrying out regular backups locally requires a great effort. These procedures, on the other hand, are part of the standard in large data centers.
The outsourcing of the accommodation , meanwhile, offers the advantage that the contracted power can be more easily adjusted to the current situation of the company. This means that if, for example, the company grows exponentially and unexpectedly, more email mailboxes can be hired without having to invest in hardware or new licenses.
The on-premises model is more suitable for large companies whose IT department has the necessary budget to integrate a secure Exchange architecture into the infrastructure itself. In this model, the acquisition of a server license provides the freedom to be able to adjust the functions of the Exchange server to the requirements of the company. Last but not least, the company remains in possession of the data it handles , which would be very different if the Exchange server were hosted on a third-party server.
