Tech Leaders can Reform Software-Defined Data Center Networks – Here’s How – Part 3

SDDCN performance requires advanced network software to deliver, manage and secure high-speed traffic flows, and network administrators need automated solutions to monitor critical applications and deliver reliable service quality. To deliver specified performance for private-cloud applications, the SDDCN combines compute resources (virtual machines and containers) and storage (disk and flash). Datacenter resources can be easily re-allocatedthrough software abstraction to address changing application requirements without altering the underlying physical computation, storage or network elements.

Here are some factors to keep an eye in order to optimize the performance of SDDNCs:

Better integrated network security

As we reach news saturation about the week’s breach, to say nothing about the thousands of breaches we’ve never heard of, network security remains the data center’s key unresolved issue. Extensive internet use, IaaS and SaaS means that companies need to defend themselves in depth and can not rely on a secure perimeter for a long time. IT organizations will continue to use Firewall / UTM and ADC devices in the data center, but they must also enable internal data center security due to the risk of a VM or container breach allowing the attacker to access other data center applications through “trusted” east-west traffic flows.

Network software provides the ability to segment / isolate critical data center assets and monitor data traffic in order to identify attacks and alter the network in order to remedy specific threats. Network software providers will need to build a broad-based security ecosystem in 2019 that integrates SDDCN elements with the wide range of network and IT security systems already deployed in most organizations.

SD-WAN to SDDCN frameworks

Many SD-WAN providers are enhancing their acceleration capabilities for public-cloud applications to ensure a high-level user experience. They also expand their connection depth with private-cloud networks and security features. With improved management/orchestration, performance monitoring and security capabilities, these SD-WAN to SDDCN integrations will expand during 2019.

Virtual application delivery controllers

Traditionally, between the firewall and the application servers, the application-delivery controller (ADC) appliance sits. Much of the inbound and outbound traffic can be seen, routed and analyzed. Software networking and virtualization has enabled ADC to be disaggregated by increasing the use of microservice-based features such as service offerings and flexible licensing. Virtual ADCs will be distributed throughout the data center during 2019, enabling container-to-container communication, enhancing security and delivering quality of service by application and/or customer.

Storage integration with SDDCN

Calculation capacity increases and the demands of new applications such as big data, video, and IoT continue to drive massive storage capacity increases. Price decreases have made flash the leading technology for new storage capacity. SDDCN suppliers focused on the network’s data side and typically minimized their capabilities for storage handling.

SDDCN suppliers will develop new features for 2019 to enable rapid storage capacity provision, scalable performance, and ability to support any type of storage with any type of compute and application. IT organizations will increasingly converge on one Ethernet network with data and storage traffic because the SDDCN supports a low latency storage traffic virtual path.
