This blog post is part of our data centre networking series:

In the previous blogs, we covered the architecture and main drivers behind software-defined networking. In this one, we discuss the impact of softwarisation on the other important data centre building blocks, culminating in software-defined data centres (SDDC). SDDC occupies a progressively larger segment of the cloud computing space, originally adopted by public cloud service providers and hyperscalers, and now finding a home with private cloud service providers, too. First, let’s consider which drivers influenced the evolution of data centres.
In the early days, IT applications were monolithic, and everything was built in a single chassis. Then information systems started progressively adopting a 3-tier architecture:
- Front End
- Back…
