Traditional networking models restrict access to infrastructure, applications and IT resources. They offer no flexibility or scalability in terms of bandwidth and lack the agility to turn up new network services that match the speed of the cloud. For an enterprise, this means having to work with multiple service providers to connect to the different cloud services. This can be complex, costly and inefficient.
WHY CLOUD NETWORKING
Chin Woon Lee
Many businesses are now using multiple public clouds for their data and applications. They need the capability to efficiently coordinate disparate workloads, manage workflows and integrate processes. A multi-cloud solution enables the orchestration of data, applications and infrastructure across several cloud environments. It simplifies cloud deployment by connecting applications and workflow processes to quickly deliver business services.
Most organisations adopt a multi-cloud strategy to fully harness the power of the cloud by taking advantage of best-of-breed services. For instance, an enterprise might be using Amazon Web Services for its compute services and Oracle Cloud for its database solutions. Businesses should have the freedom to switch from one cloud provider as their business and IT needs evolve.
With a multi-cloud strategy, businesses can mitigate risks associated with infrastructure meltdown or an attack. They can quickly move their data and applications to another cloud provider or even back-up to a private cloud. Security features can also be implemented to ensure a robust risk management system in the multi-cloud environment.
For organisations in some countries, there are laws, regulations and corporate policies that require enterprise data to physically reside in certain locations. Multi-cloud allows organisations to meet those requirements as they are able to choose multiple cloud providers’ data centre regions or availability zones.
Each cloud provider has its strength and weaknesses. A multi-cloud approach allows you to choose the best cloud provider and services that best fit your business needs. It enables greater flexibility for businesses to innovate rapidly by taking advantage of unique sets of services offered by multiple cloud providers.
A multi-cloud approach allows organisations to extend their networks to multiple cloud providers. They can interconnect distributed data centres that are in close proximity to their customers to achieve optimal performance and minimal latency. A highly optimised interconnection can be achieved through private connectivity between multiple cloud providers.
