Businesses today are accumulating more data than ever before with the need to be able to access and analyse it around the clock. Those that are naturally risk averse and less likely to spin up a new cloud service to address a resource issue and are turning towards more robust private data centre solutions.
With traditional three-tier data centre architecture reaching the end of its useful life, what are the top five benefits of next generation architecture?
1. Complete flexibility
Next generation data centres overcome the limitations of a physical server rack and geographical location boundaries, so that you can get complete flexibility from any data centre. Workloads are not tied to any specific server, rack or data centre – virtual machines can be moved anywhere you want. This is the same technology stack that powers hyperscale cloud providers like Amazon Web Services (AWS). In previous data centre architectures, virtual machines had to remain in their original place in the data centre unless fragile workarounds were put in place to move them.
2. Smarter network scaling
In older data centre architectures, if you needed better performance you couldn’t simply scale out the network if you needed to scale the data centre; you would need to scale up. With next generation data centres, you are able to add more network switches to get more bandwidth.
3. Workload mobility
Workloads can easily be shared across multiple servers, nodes or data centres. For example, a major imaging application could be running in data centres in Melbourne and Sydney at the same time, sharing workload depending on where the most resources are available.
4. Centralised management
Automated provisioning and management removes most of the manual work that network engineers need to do today to reconfigure networks.
5. Effortless service chaining
Applications today typically rely on a chain of other applications – load balancers, firewalls, and so on. Previously, this had to be carefully manually configured. In VXLAN’s software defined network, applications can be inserted into a chain on the fly to live virtual machines, or even automatically included in the chain based on the traffic type and source/destination.
