Hybrid Cloud is on a growth trajectory with its promise of overcoming challenges of traditional legacy IT systems to allow companies to embrace digitisation, fuel innovation and achieve ‘the fourth wave of industrialisation’.

In fact, Hybrid Cloud is expected to surpass its predecessor, cloud, with an estimated US$63 billion market value, according to analysts.

However, we believe investing in Hybrid Cloud will only get you 50% of the benefit without investing in a Hybrid Networking strategy.

The most important goal is often the most challenging

Industries such as manufacturing, financial services, and healthcare are heavily investing in Hybrid Cloud as their IT networks become increasingly more complex due to new services and customer demands. However, the transition from legacy IT systems is proving to be a challenge.

In Asia-Pacific, 39% of enterprises will have transitioned to Hybrid Cloud by 2020, according to The Enterprise Cloud Index. One of the key requirements for successful adoption is the ability to move applications easily between cloud environments, according to 97% of respondents to the survey.

In fact, the mobility and flexibility of moving applications across workloads is also cited as a key challenge to achieve success of moving to an ‘application first’ model with Hybrid Cloud.

This is echoed in reports that 91% of business leaders consider Hybrid Cloud to be ‘the ideal IT model’, but despite this the global average of Hybrid Cloud penetration remains at 18.5%, leaving enterprises facing a gap between their goals and a pathway to achieving them.

Bridging the gap with Hybrid Networking

Investing in a Hybrid Networking solution can make all the difference in hitting the mark on getting value from Hybrid Cloud efforts, as well as avoiding costly investments.

Enterprises need to consider the impact an end-user’s interactions with more workloads has on the ‘plumbing’ (infrastructure) of these workloads – the outcome on the network has become increasingly disjointed.

This is especially true of the healthcare and finance industries where the rise of consumerism has demanded better customer experiences on a technical level.

Critical considerations that technology and business leaders should make when reframing networking decisions for Hybrid Cloud are:

Combine SD-WAN with other networking technologies to optimise bandwidths and route traffic.

IT infrastructures are complex and there’s no one-size-fits-all solution. This means that each business requires a unique set of systems and applications across the entire stack.

This is where Hybrid Networking comes in to play. SD-WAN directly links to Hybrid Cloud, allowing for full integration at every edge of the enterprise. By combining SD-WAN over internet and tried and tested networking solutions, such as MPLS, organisations can optimise their bandwidths to meet the specific needs of their network applications, by banding multiple links together and creating an aggregate bandwidth. They can also reduce their attack surfaces and put in place safeguards that will prevent hackers gaining access more effectively.

Hybrid Networking enables enterprises to control the traffic of any application, allowing them to direct it to the appropriate Hybrid Cloud location. For example, if businesses are using Software-as-a-Service (SaaS) apps in the cloud or if running an old legacy app on-premises, the traffic can be distributed appropriately and directly as needed.

Place security and smart devices at the edge, with network visibility.

Beyond merely making the purchase, IT leaders need to ensure they are assessing end-to-end platforms for the security and visibility of their networks. SD-WAN solves this issue at the edge by aggregating a network’s entire bandwidth, deciding which path is best for each application and distributing securely. Deploying SD-WAN to a Hybrid Network allows businesses to track the performance of critical applications and adjust the network in real-time.

By operating at the edge, businesses can benefit from reduced costs, simplified and improved management orchestration of WAN traffic and devices, unified visibility and monitoring of traffic, and unified security of devices.

Making an ‘application-first’ strategy work

As more and more enterprises realise that public cloud infrastructure won’t work for all applications and data, Hybrid Clouds will increasingly become important to an ‘application-first’ approach that combines the benefits of private and public cloud services.

A successful hybrid design that provides the freedom to dynamically manage applications will be underpinned by Hybrid Networking investments. Those enterprises who adopt this approach will achieve their goals of spurring innovation, embracing a dynamic and digital business environment.
