The global market for SDN is one of the fastest evolving markets in the ICT sector with an expected growth of US $ 14 billion by 2021. Despite this considerable growth, SDN is not getting the recognition it deserves, unlike other technologies such as artificial intelligence and data analysis.
Fremont, CA: Software-defined Networking (SDN) is a network management approach increasingly akin to cloud computing technology than plugging in and setting up routers. As suggested by the name, it is all about using a software-first method to allow robust network configurations to better performance and monitoring.
SDN has gained a lot of popularity in offering ways for organizations to deploy applications. SDN technology has been an apprentice in allowing organizations to use apps at a speedy rate, reducing the overall cost of deployment. It enables the administrators to manage, and provision network services form a centralized location. As a result, more organizations have started to make the transaction to SDN.
This software-first approach not only results in centralized network provisioning but also enables administrators to have a holistic way of viewing enterprise management. SDN providing capabilities to manage both virtual and physical switches and devices linked to a network, help managers to test various configurations without adversely impacting the system itself.
SDN also allows to set up the network faster and make it more agile compared to the traditionally limited approach. Although there is a conflict on whether SDN delivers cost-savings, it does provide better security throughout applications and endpoint levels, which frees up a handsome amount of resources.
One of the most important changes contributed by SDN lies in the fact that it eliminates the reliance on hardware appliances. Instead, it delivers an enhanced virtual experience to the users. Physical access points are always needed. Still, their configurability and management will be improved through a software-based view, which makes upgrades as easy as the scalability offered by cloud data centers.
Bestowing the administrators with the ability to manage an entire organization with a single entity, features like fault-finding, adapting network requirements for precise user needs, and service optimizations become hassle-free.
This also leads to a vendor-neutral approach, as SDN is commonly focused on open standards. Businesses can easily avoid problematics network devices with no contradictory impact on performance with no vendor lock-in.
SDN equips organizations with a platform to pro-actively manage any type of potential issues on the network. Hence changes can be made on time on a better pin-point level without having to take the whole system down.
The collection of data around network traffic simplifies the process of identifying threats and compromises, which can quickly be isolated from the network and taken care of before more damage is done.
How is VMware using SDN
Network Virtualisation technology has taken SDN to the next step by decoupling network resources from hardware that is underlying. The way in which server virtualization emulates a physical server in the software, network virtualization also follows the elements of network and security services in the software.
Smarter Security with Software-first Approach
The networks are expected to provide what applications need, which can lead to security gaps. A VMware NSX based software-led approach establishes security inside the system and applications from the beginning and positions you for the things to come next in the future.
Software-Defined Storage (SDS)
The SDS strategy of Vmware is to evolve a storage framework via a pervasive hypervisor, bringing simplicity, efficiency, and cost-savings to the storage, which serves virtualization brought to compute. The underlying storage is abstracted through a virtual data plane, making VM.
On developing a flexible difference between available resources and applications, the hypervisor can balance the IT resources like memory, compute, networking, and storage, then an application requires. Vmware’s Software-Defined Storage solutions are boosting the modern data center by delivering per-application storage services, delivering rapid changes to storage infrastructures, and provides heterogeneous storage support.
