摘要：Solutions like SOA, Cloud, SaaS, Iaas or PaaS are not only buzzwords, they became a business reality because they are relative cheap and easy to use. SOA and Cloud are tightly linked because most cloud solutions are being defined using SOA making them feasible from the business perspective, because it’s hard to move to cloud when you are using a tightly coupled architecture. Big companies such as Oracle, Microsoft, IBM or Amazon offer many commercial solutions providing software as a service, as well as hosted and managed alternatives to classical deployment. For firms that are building private clouds and for service providers that are building public clouds, diverse solutions are offered by the big players for platform as a service and infrastructure as a service.
