In addition, this chapter highlighted the multitude of cloud options and the associated advantages of each option. This chapter highlighted the preference for agnostic cloud services over proprietary cloud services, to ensure a business doesn’t lock itself into a specific cloud service provider, and how adopting a service-oriented architecture can be beneficial to the business.
