“ We are migrating thousands of applications residing in multiple data centres ,” Rastogi adds . “ In a cloud transformation journey , there are multiple stakeholders : application manager , infrastructure team , enterprise architecture team , security team , operations team , licence management and the procurement team .”
“ Our central cloud team is bringing all of these stakeholders together towards a common goal , ensuring that they are all working towards the same target objectives and that they ' re following the same guidelines .”
For managing cloud adoption and transformation at Lufthansa , the central cloud team had to establish a number of guiding principles across aspects related to technical , time and financial considerations .
“ The first factor we considered was how we wanted to use the cloud ,” Rastogi says . “ We would like to use the cloud the way it ' s designed . It should be possible to use the cloud on a self-service , on-demand and payper-use , or metered , basis .”
“ We also want to use the cloud as natively as possible , meaning our implementation preference is Software-as-a-Service , followed by Platform-as-a-Service , and only in the last case , Infrastructureas-a-Service , or lift and shift migration approach . The business continuity and security requirements are directly considered in the design phase .”
As Rastogi explains , there are also guidelines related to time , to fit in with application life cycles and contractual timelines , as well as financial guidelines . “ You could spend a lot of effort redesigning or modernising your complete application ,” he says , “ but at the same time , there has to be a business case behind it . So time versus cost is always a risk-reward that you have to keep in mind .”

Making or breaking the cloud journey There are many aspects that organisations should keep in mind that could make or break a cloud journey ; the first of which is having the right strategy . “ There are modern data centres that can meet many of your requirements , but there has to be a good reason why you ' re migrating to the cloud . Cloud can be a key pillar behind your digital transformation story ,” comments Rastogi .
“ The second aspect is setting up the right structure in place ,” he adds . “ For instance , if there is a need for a central cloud team , generally referred to in the industry as the cloud centre of excellence . Similarly , one needs to decide if the journey is performed on a centralised basis or on a decentralised basis .”
“ Third is the governance part , which includes technical , security , and process
