Because of a shift in computing and the rise of the intelligent Edge,
many networking challenges still exist. At the heart of these challenges is
that networks are still bound by human scale. These challenges include
technology silos hindering agility, the lack of automation and visibility,
increasing security threats, lack of seamless access for the hybrid workforce,
and economic resource headwinds.
Some interesting statistics outline these challenges:
·
64%
of IT organisations use four or more network tools[1]
·
70%
of the IT professional’s time is spent trying to identify and diagnose issues[2]
·
80%
of organisations found IoT devices they did not install or secure[3]
·
70%
of organisations have remote workers who experience IT issues daily or multiple
times per week[4]
·
71%
of IT budgets are dedicated to ‘running the business’[5].
“Cloud networking is set to overcome many of these challenges. Research
shows that half of new network deployments will be managed via the cloud and
42% of businesses have already adopted SD-WAN[6]. In addition, Aruba’s own
research shows that IT leaders plan to increase their spending in cloud
networking by 38% and AI by 35% because of Covid-19,” says Warren Gordon,
ARUBA/HPE Business Unit Manager at Duxbury Networking, local distributors of
ARUBA/HPE technology.
“From a
networking perspective, after years of lagging behind other IT domains such as
compute and storage, the network is starting to catch up in terms of cloud
adoption. Companies are realising that in order to maximise the advantages of
the cloud, they need a network that is equally nimble, with the right forms of
connectivity into and out of cloud data centres, all the way to homes and other
remote locations. Hence, we’re seeing a rise in spending on cloud-based
networking platforms. According to IDC, overall spending will reach $10-billion
on cloud networking by 2022, with upwards of 50% of all new network deployments
being managed and delivered through the cloud,” says Gordon.
That figure is
being somewhat buoyed by technologies such as SD-WAN, which 42% of companies
are already using or are in the process of deploying to increase IT agility,
improve user experiences at remote locations, and reduce costs. There is also
artificial intelligence and machine learning, which leverage the massive
computing power of the cloud to automate and improve decision making for IT and
business leaders alike.
“And, as you
might imagine, the demand for cloud networking has also increased due to Covid-19.
Aruba conducted a survey with 2 400 IT decisions makers. A large proportion of
respondents indicated that, despite some economic headwinds, not only are they
maintaining their investments in things like cloud networking and AI, but that
they’re actually increasing their spending in the near-term. And again, that
goes back to the automation, scale, and efficiency that such technologies bring
to the network and the larger IT ecosystem. In this case, being able to scale
and manage networks from a central location, because traditional approaches to
managing networks are no longer sustainable due to travel restrictions, as well
as budget or IT resourcing constraints,” he adds.
Aruba’s response to these trends and challenges is Aruba ESP or Edge
Services Platform which is based on four core attributes:
·
A unified infrastructure that eliminates silos and streamlines operations by unifying management
of all network infrastructure across all business locations.
·
Zero Trust security to simplify the task of securing the edge for users and IoT by
eliminating the need for manual, cumbersome VLANs, ACLs, and subnets that are
untenable for today’s IT.
·
AIOps,
which gives networks a ‘6th sense’ so customers can resolve issues
before they impact the business or at least resolve them faster so business
keeps humming.
This is all delivered with As a
Service flexibility, which gives organisations greater choice and
control over how they consume and pay for technology to accomplish their goals.
“Aruba Central allows the breakdown of silos with
unified management and AI operations, using a cloud-native single pane of glass
for simplified operation and deployment flexibility across all infrastructures
and all network domains. In research undertaken by the Enterprise Strategy
Group[7], Aruba ESP has been shown
to reduce operational costs by 56% over three years,” says Gordon.
Aruba Central delivers AI- and machine learning-based
analytics, and with these insights, customers can preempt issues before they
impact end users or the business, while also proactively identifying areas for
improvement. This includes a rich set of troubleshooting tools and guided
remediation for quick and accurate fixes.
On top of the AI engine, Aruba Central also provides
an array of other powerful monitoring capabilities, giving customers broad
visibility into key performance indicators and complete operational awareness.
“Security is always top of mind, especially given that
the traditional IT perimeter continues to dissolve due to workplace mobility
and work-from-home initiatives, along with the proliferation of BYOD and IoT
devices on the network. To that end, Aruba Central was designed with security
built-in, not bolted on, with capabilities like unified threat management,
IDS/IPS, device fingerprinting, and automated policy enforcement for users and
devices across both wired and wireless networks,” says Gordon.
With a cloud networking solution like Aruba Central,
IT admins have the ability to remotely control, configure, and push necessary
changes to all devices in the network from a single management console. Be they
access points, switches, branch gateways, or even VPN infrastructure. This
means the ability to automate and orchestrate network-wide workflows,
dramatically simplifying day 0 to day N operations.
“Another key
capability of Aruba Central also involves an element of automation – applying AI-powered
insights to surface, preempt, resolve, or even prevent network issues.
Generally speaking, nearly 75% of IT’s time is spent trying to track down and
resolve these user- and business-impacting issues. So skilled IT staff are
continually pulled into reactive firefighting mode to resolve user-reported
complaints, and often, the network is the first to be blamed. Artificial
Intelligence (AI) is needed to shift IT operations from a reactive to proactive
posture.
“The three key
components of this AI-powered intelligence are AI Insights, the AI Assist
feature and the AI Search feature. With this portfolio of features, Aruba AIOps
is able to help redefine IT outcomes by reacting to and resolving issues faster,
predicting and preempting issues before they impact the business or users,
continuously optimising network performance based on peer benchmarks. And most
importantly, it can identify specific root causes, specific recommendations and
deliver these outcomes with greater than 95% accuracy,” says Gordon.
Aruba Central powers the hybrid workplace through:
·
Remote
Access Points to extend enterprise services to the home.
·
Simple
workflow. IT ships an AP to the employee’s home; the employee plugs it in,
downloads a configuration from the cloud, and they are ready to go.
·
Alternatively
deploying a plug-and-play VPN agent (Aruba VIA software client) that is equally easy for non-IT personnel to
install and use.
