Windows Server 2019 CALs: optimised security and more user-friendly
The Windows Server 2019 CALs provide access to the operating system of the same name, designed for data centres and corporate server infrastructures. The initial release was on 2 October 2018 – with a clear focus on Windows 10. This constitutes a definite shift away from Windows Server 2016, which was still part of the Windows NT family. So users who purchase one of the Windows Server 2019 CALs gain access to many new features. This makes it a worthwhile acquisition even for users who are equipped with an older version of the operating system.
Buying one of the Windows Server 2019 CALs: the most significant new features
- greater security thanks to a comprehensively improved Windows Defender System
- compatibility with Linux
- hardware and network can be monitored on a system-wide basis
- full support for IPv6 for networks
- Kubernetes support
- Azure hybrid potential
- enhanced development options for cloud-native apps and updates for older applications
These innovations in Windows Server 2019 are particularly important for data centres
Many data centres work with Linux or Mac OS (or Unix) because older versions of Windows Server were too insecure. There is a certain inevitability that data centres will be a particular target for hacking attacks. Microsoft has responded to this threat: the Windows Server 2019 CALs provide access to an operating system with significantly enhanced security features. Windows Defender has been comprehensively revised. Threat definitions, for example, are automatically updated. Analysis of potential attacks and corresponding responses take place autonomously and in real-time. Specific folders can be given special protection. In conjunction with Azure, automatic backups can also be put in place.
Windows Server 2019 also allows the creation of specially shielded virtual machines (VM). In data centres where multiple client VMs are running on the physical servers, this means there is no longer any need to worry about malware spreading between VMs. Data integrity on the virtual machines is also ensured thanks to this shielding approach.
Windows Server 2019 uses virtual peering to monitor all hardware elements and the network in its entirety. Each machine (whether virtual or physical) functions as an alarm signal for the others. Thanks to system-wide support for IPv6 (Internet Protocol version 6), all data transmissions can also be encrypted at source.
Another benefit for data centres is the support for Linux via the "Windows Subsystem for Linux". This allows Linux application executables to be used under Windows Server. Data centres that have previously relied on Linux and would now like to switch to the Microsoft operating system do not need to undergo a complete conversion. Instead, the Windows Server and Open Source operating systems can work side by side.
These new features in Windows Server 2019 are beneficial for companies
Companies that purchase one of the Windows Server 2019 CALs benefit from Kubernetes support. Container applications are automatically provided, scaled and managed, which is extremely useful for working in conjunction with cloud-based systems. The operating system also provides companies with optimal tools for developing cloud-native apps. Meanwhile, older applications can also easily be upgraded using these tools. There is support for all current development languages (Swift, Java, Kotlin, C++, etc.).
The licensing model
Windows Server 2019 CALs are either linked to users (identified as USER) or to devices (DEVICE). Buyers can choose offers for one or ten CALs for users or devices. The 10-license packages include a discount, which makes them particularly suitable for companies or data centres where multiple devices need to be set up.
