text: **Platform as a service (PaaS)**
  Development companies and factories that want to implement agile methodologies are the 
  most suited for PaaS. PaaS providers publish many services that can be used inside 
  applications. Those services are always available and up-to-date. PaaS provides a simple 
  way to test and prototype new applications. It can save money when developing new services 
  and applications. Applications can be released more quickly than usual to get user feedback. 
  
  The API economy is the new paradigm in development. The cloud provides the perfect 
  platform for its implementation. 
  
  **Software as a service (SaaS)**
  At the time of this writing, SaaS patterns are accepted by many companies that want to 
  benefit from application usage without the need to maintain and update infrastructure and 
  components. Mail, ERP, collaboration, and office apps are the most accepted SaaS solutions. 
  The flexibility and elasticity of the SaaS model are great benefits. 
  
  No “one-size-fits-all” solution exists for cloud adoption. Companies must consider their own 
  cost and benefit equation and then decide on the best model. Each application and process 
  that is needed is a workload. A deep workload assessment is normally performed by 
  companies that decided to move to the cloud.
