CIO OPINION edge is paramount . This requires organisations to move away from traditional MPLS architectures . Backhauling network traffic through the data centre creates severe latency and bottlenecks for end-users in branch offices and remote sites , preventing them from moving at the speed of business .
Modernising with more agile cloud access to applications like Microsoft Office 365 requires a different infrastructure . One where DDI services can be delivered and managed centrally via the cloud and where traffic from remote locations can connect directly to the closest local PoPs in the cloud without the backhaul bottleneck .
Boosting survivability at the Edge
With today ’ s rapidly expanding distributed workforce , getting secure access to cloud apps and data as if working from headquarters is a game changer for your employees – and your network management team .
services in small regional offices . Similarly , it may wish to expand DDI capabilities in some branches but not others .
Just as common , especially for enterprises that are undergoing Digital Transformation , it ’ s important to have the flexibility to roll out DDI capabilities incrementally . They may wish to upgrade DHCP in the near term while keeping their current IP address management solution . They need a DDI solution that protects them from over-provisioning services in remote sites that may go unused for some time yet .
Cloud-based DDI provides the flexibility and agility for enterprises to achieve the right size DDI implementation for every location .
Simplifying application access at the Edge
For the borderless enterprise , with growing numbers of remote workers and branch locations , simple , reliable access to mission-critical applications at the network
Application latency is not the only downside to traditional backhauling of DNS and DHCP through a headquarters data centre . Backhauling also puts Business Continuity at risk for branch offices and remote sites because backhauling does not provide local survivability for DNS and DHCP services .
If the link to headquarters goes down , because of a power outage or natural disaster , remote locations are not able to reach the central data centre for DNS and DHCP resolution . As a result , they lose access to the Internet and cloud-based apps .
To ensure always-on networking for all locations , remote and branch offices need the ability to maintain DDI services locally .
Scaling at the Edge
Typically , core DDI services like DHCP are managed by hardware routers or servers located at each site . A large enterprise may have hundreds of these throughout its borderless operations .
These on-premises devices are often resourceintensive , error prone , cumbersome and hard to scale . In addition , they provide no easy way to monitor and manage multiple locations .
For cloud-born businesses , cloud-managed DDI makes it simple to eliminate resource-heavy physical appliances in branch and remote offices . Instead , lightweight devices or virtual appliances can be deployed in all locations , which enables DDI to be centrally managed in the cloud across all sites .
To sum up , traditional networking architecture is no longer effective for managing the explosion of workflow at the Edge . Cloud-managed DDI is a great modern networking solution for the borderless enterprise . p
