KEMP Technologies looks at the changing network and more technology trends to look out for in 2016
While the last 10 years have seen network functions consolidated into a single physical appliance, the move from the physical to the virtual world is now producing the opposite effect that will accelerate further in 2016, according to KEMP Technologies. This decomposition of the network will see more network functions migrate back to their constituent parts and this trend to network function virtualization will increasingly change the way networks are designed.
"Virtualization removes the boundaries of where network capabilities need to run, so that functions can be deployed where its makes more sense," says Jason Dover, Director of Product Line Management at KEMP Technologies. "For example, since virtualized network functions can be placed closer to the end user, compute power can be distributed around the edge of the network, reducing the need for packets to be routed all the way to the data center, which is critical for low latency networks."
Dover points to how the capabilities of traditional load balancers were extended to include WAF (Web Application Firewalls), IPS (Intrusion Prevention Systems), firewalls, SSL accelerators, compression and caching, and became known as Application Delivery Controllers (ADCs).
"But what makes sense in the physical world no longer make sense in the virtual world," says Dover.
"In the ADC use-case, we might now place the firewall or IPS at the edge, while keeping load balancing capabilities close to the application within the datacenter. This will prevent 'bad' traffic from having to traverse the entire network and ultimately off-load the datacenter."
As well as the increasing decomposition of the network, KEMP's Jason Dover also sees other trends emerging further in 2016:
Business adoption of 'Internet of Things'
While the connected fridge and toaster are well away from the mainstream, innovative businesses are now embracing IOT to improve information gathering and analysis and as the foundation for automation and control. The scope for IOT deployment will be increasingly applied to large and complex entities such as manufacturing plants. This evolution will drive not only an increase in data volumes and sources, but also require additional layers of security and application delivery. These additional layers will be delivered in a virtualized environment as dynamic microservices that can dynamically adapt...
