Businesses are beginning to question whether SD-WAN solutions are appropriate for remote workers just four months after the epidemic. According to a new study from Accelerate, half of UK businesses see the technology as less beneficial.
Businesses are tending towards a single cloud (opens in a new tab) service model SASE, which combines SD-WAN features with cloud-based security. According to Accelerate, enterprises believe WAN optimisation works well enough and prefer to go for centralized security and a single point of public entry.
Disadvantages of SD-WAN
Respondents with no intentions to deploy SD-WAN claim it doesn''t support worker access (remains afloat in SD-WAN, despite the majority of businesses saying it does exactly that) and it''s too difficult to choose a suitable technology partner or skilled individuals in the house.
Darran Clare, the Director of Technologies at Accelerate, said the move toward SASE architectures is a logical step.
"We see evidence that WAN optimisation is far from dead," said a senior advisor. "These services can play a crucial role in improving cloud hosted applications, where latency is the main issue."
"Whilst most SD WAN and SASE vendors will advertise WAN Op capabilities, such claims should not be taken at face value as the scale and depth of application optimisation can vary greatly.
For the majority of businesses that received the report, key challenges include managing remote worker performance and support. Near half had problems with bandwidth, infrastructure capacity, and the increase number of dispersed and unmanaged devices.
