As mentioned in the introduction, cloud architectures are a main driver behind network virtualization—and a primary customer for NV and SDN controller technologies. We believe many enterprises will first experience the benefits of NV as a service from one of the major public cloud providers. And we are seeing many innovations from the cloud providers in terms of cloud networking and network virtualization and believe that it’s important we extend our report coverage to these platforms. With that in mind, we’ll dig into more detail around cloud trends and what it means for NV as a market.
Every day in tech news is more of the same, cloud and containers, cloud and containers. Although network engineers are probably tired of hearing about them, no matter where you turn there are signs that two distinct yet related technologies are reshaping enterprise IT and digital strategies writ large. Both public cloud services and application containerization, often used together, are rapidly becoming the foundation for a new generation of business applications and supporting IT infrastructure. Just as network pros have adapted to server and associated network virtualization, along comes a pair of complementary technologies that promise to change how enterprise networks are designed, built and operated. We’ll dive into the details of each and, more importantly, the networking implications, but first let’s review what business executives are reading since it will be shaping CIO plans (and performance reviews) for the coming years.
Public cloud is solidly mainstream with most enterprises, and one look at the financial results at Amazon, Microsoft, Oracle or SAP shows how rapidly organizations large and small are adopting cloud services. However, the cloud era is still young as it evolves into a pillar of digital business. Indeed, most of the blue chip IT analyst and consulting firms continue to feature public cloud as one of the most significant technology trends. For example:
