There is no doubt that 2020 has been a pivotal year for cloud migration. Organisations everywhere have sped up the process of moving applications across to multiple cloud platforms in response to unforeseen and exceptional factors.
Along with this move has come a sharpened appetite for a break with the past. When we look back on 2020 five years from now, we may well see it as the year when the world finally moved on from a longstanding reliance on traditional legacy architectures in favour of cloud-native ones. Only a true cloud-native approach can support a multi-cloud strategy and deliver the flexibility and simplicity that CIOs now see as essential if they are ever to align their IT with the fast-changing needs of the business it serves.
When it comes to applications, this is all about the use of containers, microservices and APIs, and taking on a new dynamic approach to building applications that recycles and replicates existing applications in new ways. The astonishing rise of Kubernetes is testament to this trend.
This new era of agility and responsiveness at the level of the application now needs to be matched in the network. CIOs want cloud-native principles to be evident in the connectivity that supports their cloud-based applications. SDN and SD-WAN have taken us a long way down this track, but not all the way. SD-WAN was not designed with mobile users or the mobile edge in mind, for example, not indeed with the security which a highly fluid workforce demands.
Additional attributes can be engineered on top of SD-WAN. But what enterprise networking is crying out for is a whole next level, and that means true cloud-native networking that mirrors cloud-native application development.
True cloud-native networking requires a software-based platform designed from the ground up take advantage cloud’s attributes. The platform will take charge of route calculation, policy-enforcement and security inspections. Affordability is assured through support for a multitenant cloud model and by reliance on off-the-shelf server power. The demise of proprietary appliances wedded to multitenancy changes the economics of enterprise networking forever, without the sacrifice of an ounce of performance.
When it comes time to scale up your cloud resources, a cloud-native network will facilitate that. The software stack lets you add compute, storage, memory or networking resources when you need them. Cloud-native networks can extend your business to new regions in hours and days, not months.
In a digital business, resources must be available everywhere, accessible from many edges. A cloud native approach means you can use the one network to connect any resource, anywhere. A cloud-native network is built with cloud DNA from scratch, representing a real revolution in network architecture and design.
If you want to find out more about this exciting new world, then this event should be regarded as essential. Chaired by Scott Raynovich, Chief Technology Analyst with analyst firm Futuriom, it will range over many cloud-native issues and challenges, and consider the new network approaches that will drive tomorrow’s cloud.
The following companies are among the leaders in the cloud native space:
