The entry of SDNs along with network virtualizations has helped significantly to control intricate data network traffics through integrated software technologies.

Traditional IT infrastructures are in for a complete revamp with the entry of SDNs (Software Defined Network) for the control and maintenance of complex network traffic patterns. This has also been augmented with the integration of hardware with cloud computing technologies. Enterprises and business organizations usually face trouble in preserving data and channeling it to the right sources without causing intricate traffic in their internal setups. However, SDNs are here to the rescue, where the highly complicated nature of raw data networks can be mastered through a single point of control. The industry faces a magnanimous growth as there is an added need for non-integrated software elements that are compatible with any hardware device, or on the cloud. This means a major potential for the IT industry as the software defined networks are a leap towards more efficient IT infrastructures.

"SDN allows implementation of firewall systems, encryption techniques, multi-factor authentication controls and stringent user access policies under one simple control"

The development of software defined networks has helped in the creation of adaptive and intelligent networks. These can help manage both structured and unstructured data in big data analytics. Growing need for mobility services, along with the rising trend of big data analytics is ensuring that the SDN market is well on its way to thriving as an important industry. Companies are recognizing the demand for developing networks in different regions of the world, and cashing in accordingly. Experts at Allied Market Research predict that the North American region are open to early adoption of fresh technologies. They also believe that Asia-Pacific countries pose a promising picture as the fastest growing markets.

The NFV-SDN synergy

The deal with complex IT infrastructures is that it usually requires dedicated hardware devices in order to build a service chain. It is highly imperative for the network administrators to make network services more functional and flexible. By setting up a software defined network, they can separate the network’s control plane across varied hardware and integrated circuits. This will allow administrators to gain a centralized traffic control and eliminate the need to use numerous individual switches. Network Function Virtualization (NFV) is another information technology that is different from SDN. These two technologies when combined, will complement each other and advance the other’s capabilities in network managing. When used in harmony with each other, SDN and NFV will simplify network designs and operation capacities by making it more flexible and adaptable. Such synergy between the two will ensure it gives a real boost to the SDN market.

SDN forefront promises dynamic market competition

As software defined networks propose a seemingly new way of designing, maintaining, and operating IT networks with a grip on the flow of raw data, IT companies are lining up to cash in on this trend. An increasing number of market players wish to solidify their stronghold on the industry, by targeting a large consumer base. By diversifying their product offerings and ensuring that they keep up with the latest cloud serving trends, businesses are striving to stay top-notch in the game. It is not unheard of to see big names partnering up and combining their resources to expand their reach to the end-users.

One such example is the recent partnership between Oracle and Verizon. This new collaboration is targeted at making the transition to cloud services easier for global organizations. Verizon will provide its software defined network, which will be coupled with in-region connectivity from Oracle, making it a win-win situation for customers.

In the words of the Verizon’s vice president of enterprise networking and innovation, Shawn Hakl, “Verizon Secure Cloud Interconnect for Oracle FastConnect allows users to connect to applications simply, securely and reliably.”

Digby Malakar, Oracle VP product management also added, “With Verizon’s leading Secure Cloud Interconnect service, Oracle customers can benefit from the latest in networking technology as they continually groom their networks to handle the demands of their business.”

High number of end-users for SDN benefits

Software defined networks are proving their mettle in simplifying control over data flow and ensuring information security through traffic regulation. The software is programmed to recognize the regular traffic patterns and allow for seamless flow. It also detects irregular traffic flow and accordingly determines if it might be a threat to network security.

SDN has found a lot of takers in enterprises that wish to regulate their networks. It has provided its end-users with a centralized control logic through separation of control and forwarding planes. The telecom, healthcare, and cloud service providers are increasingly adopting this advanced technology and establishing interoperability, validity and certification of their personal networks.

Even security concerns about the data have propelled the early acceptance of software defined networks across various verticals. The centralized control permits network administrators to detect and manage all known security threats prematurely, under a single window. SDN allows implementation of firewall systems, encryption techniques, multi-factor authentication controls and stringent user access policies under one simple control.

Apart from combating the threat posed by data breaches, SDNs are also considerably profitable to business owners, as they are an effective cost-cutting measure. Operational costs incurred by the organization are significantly reduced and the resources of the firm can be employed elsewhere. Moreover, software defined networks are an added leverage to the business, as adapting to this technology ensures that all their corporate data requirements work in sync with cloud efficiencies.

Outdated network systems are a thing of the past and are not compatible with cloud networks. This is a major reason why businesses are fast approaching big brands such as IBM, HP, Cisco Systems, Inc., and Juniper Networks, Inc. to cater to their SDN needs. Adoption of SDN has proven to add an extra competitive edge to firms and ensures that it works to their advantage. The software defined network industry is fast establishing itself as a market to look out for as an advanced information technology infrastructure.
