Question about Intracloud Networking

Page 20 mentions that private intracloud networking is usually supported over connectivity between the major data center sites owned by the company.

Also, private intracloud networking links users with the resource.

I don't understand how can an application be componentized based on service-oriented architecture (SOA), which is mentioned on page 21.

What does this mean?

It says that the traffic may then move between components of the application.

What do these components refer to?

Thanks.

Most of the performance issues and violations from these are addressed in the SLAs commercially connectivity in cloud computing is private intracloud networking What makes this particular issue so complex is that it depends on how much intracloud connectivity is associated with the applications being executed in this environment. by the company At a minimum, all cloud computing implementations will rely on intracloud networking to link users with the resource to which their application was assigned 21 3.3.5 New Facets in Private Networks Once the resource linkage is made, the extent to which intracloud networking is used depends on whether the application is componentized based on service-oriented architecture (SOA) or not, among multiple systems If the principle of SOA is followed, then traffic may move between components of the application, as well as between the application and the user The performance of those connections will then impact cloud computing performance overall. Here too, the impact of cloud computing performance is the differences that exist between the current application and the network relationships with the application Conventional private networks have been architected for on-premise applications and maximum Internet security. Typically, applications such as e-mail, file sharing, and enterprise resource planning (ERP) systems are delivered to on-premise-based servers at each corporate data center Increasingly today, software vendors are offering Software as a Service (SaaS) as an alternative for their software support to the corporate offices, which brings more challenges in the access and usage mechanisms of software from data center servers and in the connectivity of network architectures
