I was recently asked this question . . . And with much of the cloud hype being centered on software, storage, virtualization and Xaas, I thought it might be helpful to pull together a quick post around the implications of cloud computing on network.
As you turn to cloud computing to accelerate business innovation and contain costs, you need to be keenly aware of how cloud (and virtualization) reshapes the way applications are deployed and consumed and influences your data center network design.
While the deployment types may vary—private, public or hybrid cloud—the higher performing computer engines that drive these new cloud-use modules have much in common. For example: increasingly powerful multi-core-processor (blade) servers, higher-bandwidth/density 10 GbE interfaces, driving virtual machine scaling measured in the thousands all deployed in a single rack.
These larger-scale solutions dramatically increase network performance requirements at the server edge and across the extended network. More over, virtualization and vMotion/Live Migration introduce high-volume machine-to-machine traffic flows that blur the traditional boundaries between the network and server administrators and physical and virtual worlds.
Evolving enterprise networks to support cloud models
So what’s my point? The bottom line is that contemporary data center networks designed to support siloed IT architectures simply aren’t designed meet the performance, security, availability and agility requirements of cloud.
The table below details how your enterprise networks need to rapidly evolve to support emerging cloud use models:
As IT/network operators begin to think (or re-think) about how you will build and design you networks moving forward to accommodate emerging cloud use models, you would be well served to consider HP’s FlexNetwork Architecture.
HP FlexNetwork Architecture: why it’s right for supporting cloud computing
Our HP FlexNetwork Architecture allows enterprises to securely deploy and centrally orchestrate cloud-optimized architectures that scale from the data center to the network edge. HP FlexNetwork enables the construction of flatter, simpler data center networks to support the bandwidth-intensive, delay-sensitive server-to-server virtual machine and workload traffic flows that accompany cloud.
The benefits of HP FlexNetwork Architecture include:
- Massive architectural design simplification, connecting users to applications
- High-performance, low-latency, ultra-resilient virtualized networking fabric
- Open standard-based networks designed to lower operational complexity and cost
HP’s Building Cloud-Optimized Data Center Networks is a helpful resource if you are looking at how to best “cloud-optimize” your network to address the new generation of requirements that cloud demands.
