When Windows Server 2019 is released this fall, the updates need to include features that enterprises might use to leverage software-defined networking (SDN).
SDN for Windows Server 2019 contains a number of components that are fitted with attracted the attention of early adopters including security and compliance, disaster recovery and cusiness continuity, and multi-cloud and hybrid-cloud.
The ultra-modern virtual networking peering functionality in Windows Server 2019 allows enterprises to see their own virtual networks within your same cloud region by backbone network. This provides you with the ability for virtual networks to be as a single network.
Fundamental stretched networks have been about for years while having provided organizations be able to put server, application and database nodes in sites. However, the contest has always been the IP addressing for the nodes in opposing sites. When there are only two static sites in a very traditional wide area network, the IP scheme was relatively static. You knew the subnet and addressing of Site A and Site B.
However, throughout the public cloud and multi-cloud world – where your target devices might shift between racks, cages, datacenters, regions and maybe even hosting providers – having addresses that could perhaps change by considering failover, maintenance, elasticity changes, or network changes provides a problem. Network administrators have spent and will drastically improve the amount of time they spend addressing, readdressing, updating device tables, etc to maintain the dynamic movement of systems.
With Vnet Peering, while external location and fabric which a host and applications systems are running in may drastically change, the virtual network remains consistent. No have got to change source and target addresses while in the application, no requirement for Web and Database pairs to convert settings.
Another significant improvement in Windows Server 2019 will be ability for virtual-network individuals to be encrypted between virtual machines. Traffic encryption is just not new to this is a, however having the encryption inbuilt with to the system as the foundation of hypervisor communications, server communications and application communications provides both flexibility understanding that in the past was frequently done inside application layer.
Now with Vnet encryption, entire subnet communications between host servers can be protected, and they all network traffic within that network is automatically encrypted. For organizations aiming to ensure communications between a Web server including a database server is encrypted, Vnet encryption in Windows Server 2019 is usually enabled. Considering that communications is actually the network/subnet level, if additional Web frontends and backend databases needed to be added, those of you servers join equivalent encrypted communication stream, offloading the secured communications outside of the application itself, improving performance and efficiency.
A number this protection can be accomplished by isolating servers and systems for a passing fancy VLAN, but organizations can another way and quickly encrypt the communications between systems becoming a method of secured communications and knowledge protection. As organizations appearance versus enable protection through software defined controls and eliminate complexities, configurations leveraging virtual network encryption greatly enhance security in a simplified manner.
Other SDN improvements in Windows Server 2019
Lots of additional SDN features added and enhanced in Windows Server 2019 include:
Auditing enhancements: Windows Server 2019’s SDN settings experience an extremely helpful firewall-auditing component that can be enabled to log all network communications between SDN connections. The comprehensive data available provides source and destination traffic information, and makes for ACLs on site provide control, management and logging.
Support for IPv6 in SDN configurations: Windows Server 2019 SDN provides IPv6 address configuration for virtual machines from the virtualized network environment. For organizations leveraging IPv6, or perhaps supporting IPv6 in system-to-system communications, the normal process to enable, configure, track and manage IPv6 addresses currently is built in to SDN.
IPv6 load balancing, gateways, and firewall rules: With IPv6 support in SDN configurations in Windows Server 2019, organizations create IPv6-supported load-balancing, gateways and firewall rules. This allows SDN controls beyond just routing IPv6 traffic, as well as provides core SDN functionality supporting IPv6.
Performance Improvements: As with most updates, mishaps improvement in simplifying tasks and improving performance, as well as in the case within the SDN in Windows Server 2019, there’s improvements in overall simple configuration and also gratifaction. One significant method to note from early implementations may be a 2x to 3x performance improvement inside SDN Gateway, particularly IPsec VPN tunnel communications. These also decrease CPU utilization and also will allow SDN to scale more significantly for giant scale environments.
