A data center is nothing more than a logistics company which makes digital information (bits) available to the applications of business at the right time and under the proper conditions. In order to achieve this a data center offers computer power, resources or, in more generally terms, it offers workloads.
The logistics process has become increasingly complex. Partly due to inter connecting more and more networks, and partly due to coupling of a variety of front-end devices (FA’s) such as workstations, telephones, laptops to the network. All of these FA’s require additional new ICT solutions andthese new solutions generates an exponentially demand for IT. The increased demand for IT creates a higher dependency and thus higher impact on the business.
This demand and the accompanied dependency stimulates the necessity for an increase of the availability in various ways. Today, the infrastructure is on a number of crucial parts of the infrastructure doubled. The bits run from the source to the target through various digital highways to sometimes very geographically locations. ICT is therefore able to divert the workloads. In addition ICT can distribute the workloads in line and simultaneously on the different geographical spread infrastructures. All these possibilities comes with a price. Everything now a day is becoming complex from a logistics perspective for delivering bits at the proper site under the right conditions. Needles to say that more tools and better control is needed.
Not only the deflection and the distribution of workloads increase the complexity of the delivery of the bits. Also the extreme requirements to deliver digital information is becoming more and more limited in time (RPO set to almost zero / and RTO of seconds). This requires a lot of the logistical process for the delivery of the bits; both technological and organisational.
We also see a growth of managed hosting companies and Cloud providers. Each hosting & Cloud provider has its own support, focus and services. At the same time you see an increase of customers going to the Cloud. Both developments provide multiple data streams between clients and providers on the one hand, and providers themselves on the other. Until recently, workloads were distributed across data centers within a single provider, but in the near future workloads are going to be distributed among different providers anywhere in the world.
All of these developments contribute to the complexity for supplying bits between source and final destination. Time to take a good look at our logistics process in which we analyse in a holistic and integrated approach Data Centers and take into account that processes, people and technology contribute to the logistics of a data center.
