Today's world, driven by the exponential growth in technology performance, has become
increasingly connected, digitized, distributed, and diverse. With every "thing"
possessing the power to process data, compute models are poised to become dramatically
more distributed and networked. And as devices and users are added, the value and
importance of the network continues to grow exponentially.
For an organization to flourish in the digital economy, the network needs to be able to
adapt quickly to changing business requirements. The network needs to support an
increasingly diverse and fast-changing set of users, devices, applications, and
services. It needs to seamlessly and securely onboard this diverse set of devices and
deliver the desired user and application experience.
Network needs to ensure fast and secure access to and between workloads wherever they
reside. And for the network to function optimally, all this needs to be achieved end to
end between users, devices, apps, and services across each network domain-campus,
branch, remote/home, WAN, service provider, mobile, data center, hybrid cloud, and
multicloud.
Organizations need a new, integrated architecture for each network domain, one that is
customized to meet the specific needs of that domain and that provides a way to
communicate and enforce consistent policy across all domains.
GREENNET has enough expertise to help organization adapt new networking technologies and
meet challenging business needs.
Network automation is becoming a necessity rather than a nice-to-have. Today, there is
an exponential rise in the number and type of devices, users and things getting
connected to the network. And to fulfill that increasing demand, networks are getting
more complex & deployments getting massive.
Network Automation plays a very crucial part in not only simplifying the Day-0
deployment process, but also simplifying day-to-day operations and maintenance.
Network automation is the process of automating the configuring, managing, testing,
deploying, and operating of physical and virtual devices within a network. With everyday
network tasks and functions automated and repetitive processes controlled and managed
automatically, network service availability improves.
Networking automation capabilities transform previously manual onboarding,
configuration, provisioning, and software management processes to simplify and scale
network operations and greatly minimize configuration errors.
Enterprises across the globe are looking to embrace advanced network architectures to
ensure their networks serve the needs of their modern digital businesses. Legacy systems
for manually onboarding clients and devices onto the network simply do not scale when
employees, customers, and partners are each bringing multiple devices on to the network
and expecting frictionless mobility throughout the enterprise. The cost of inefficient
network
management has never been higher, businesses rely on the network for mission-critical
tasks. For many organizations across the globe, if the network is down, the business is
down. Yet often, organizations are relying on manual, ad hoc processes for managing the
enterprise network. There are myriad reasons this is not the ideal state of
networking:
- Inconsistent policies across networks, specifically wired and wireless networks, result in complexity in managing separate networks and inconsistent enforcement of policies across the network.
- Inefficient or imprecise onboarding, segmenting, and implementation of access and usage policies for all users and devices on the network creates security holes and produces inconsistent performance.
- Lack of visibility, both at a high level and granular detail, means network operators do not have the ability to see what’s happening on the network in real time, including which users and devices are on the network and which applications they’re accessing.
- Slow identification of problems, inability to determine the root cause of the problem quickly, and inefficient processes for remediating problems or security incidents within the network cause business to lose opportunities and users to become frustrated and inefficient.
Although every industry and organization is different, everyone needs a reliable
wireless network. Freedom to access the network from anywhere within the signal range
and move devices around without losing the connection, connect any mobile device,
laptop, etc. with no extra work required these are the main advantages of wireless
networks.
An enterprise-grade wireless network is more than just a collection of WiFi Access
Points. At the minimum, it’s characterized by superior security and performance;
centralized configuration and management; and a much higher capacity for user density.
Previously it was thought that wired networks were faster and more secure than wireless
networks. But continual enhancements to wireless network technology such as the Wi-Fi
6/6E networking standard have eroded speed and security differences between wired and
wireless networks.
The shift from on premise to cloud-based applications and from MPLS to Internet based
connectivity requires IT to rethink their approach to enterprise networking. Features
related to scalability, security and performance become even more important in a world
where cost optimisation is a constant priority.
Traditional enterprise networks rely on MPLS circuits from telecom service providers to
connect their sites to main data centres, where corporate applications are hosted and
Internet gateways located. For companies with various sites distributed geographically,
this leads to an increased network spend, as additional MPLS capacity will become a
problem, as the network becomes a bottleneck for accessing corporate and cloud based
applications. In most cases capacity is required to accommodate all the traffic, and
performance issues, whenever there is congestion on the links.
Software Defined Networking applied to the WAN is a software solution that provides a
mechanism for improving traffic management across MPLS and Internet links. From a
technology perspective, SD-WAN abstracts the underlying transport solution to provide
seamless hybrid WAN connectivity. The solution provides a number of features that enable
companies to take the most out of their WAN. On the security level, end-to-end traffic
encryption is available, alongside security policies that are centrally defined and
implemented across the entire network in an automated way. Moreover, the centralized
management platform enables visibility over the entire network, while allowing for
real-time scaling of network resources. SD-WAN also acts as an enabler to improve
network performance, through features such as dynamic routing path selection, which
optimises the utilization of the available connections for both on premise and cloud
traffic, and automation with zero-touch provisioning capabilities.
