A key feature and advantage of cloud computing is its flexible scalability. For example, if a 
web application receives an unusual amount of traffic, additional servers can be created to 
provide  that  service.  Therefore,  the  application  can  scale  properly  and  automatically  on 
demand. 
Scalability also enables profitable workloads that require a large number of servers but only 
for  a  short  or  occasional  period.  Many  clients  have  such  workloads  and  can  be  very 
profitable, especially  if capacity  is  available. Digital Transformation is also  taking  place 
here. 
                                 
Measurement service 
Cloud services generally charge users based on the use of resources per hour or based on the 
number  of  certain  types  of  transactions that occur, the amount  of storage  in  use,  and the 
amount of data transferred over the network. 
 
Cloud service providers will also be able to optimally allocate physical computing resources 
to  all  customers  to  maximize  their  SLA  commitments  and  minimize  the  cost  of  service 
delivery. Use measures to make decisions (thus maximizing margins and competitiveness). 
Service level agreement 
Many  cloud  services  offer  service  level  agreements  that  guarantee  a  certain  level  of 
availability,  performance,  or  capacity.  Lower  priced  service  tiers  generally  do  not  have 
warranties, but higher tiers are designed to provide specific warranties. Large companies can 
usually negotiate guarantees of personalized service. 
Multi rent 
A distinctive feature of public cloud services is multiple tenures. The infrastructure serves 
multiple  clients,  and  in  SaaS,  the  same  virtual  machine  can  serve  multiple  clients. 
Compliance  requirements  may  require  services  to  run  on  a  dedicated,  non-shared 
infrastructure. Such location eliminates certain security risks, such as virtual machine escapes 
and  the  spread  of  attacks  to  other  clients  running  the  same  infrastructure.  Many  cloud 
services provide dedicated servers to counter this.
