Where will SOA and cloud converge?

"The Focus on SOA (service-oriented architecture) is beginning to shift to the cloud," said Steven Martin, senior director of Microsoft Development Platform technology. The cloud is the logical hosting environment for the service. Service-oriented is one way to build an application, while the ' cloud ' represents the architecture and the publishing model for that application. ”

"SOA is a type of architecture for building applications," says Jerry Cuomo, chief technology officer at IBM's WebSphere department. Can we build a data center infrastructure based on SOA principles? The answer is yes, and that's the cloud, so the cloud is a service-oriented infrastructure. He added: "The cloud is about adopting the architectural principles of SOA and applying it to the infrastructure." ”

The adoption of SOA can help companies prepare for cloud computing, says Tim Hall, SOA product director at HP's software division. He says the challenge for the organization is how to support service components internally-using cloud services can exacerbate this problem. Service-oriented SOA and cloud have a lot in common, he says, for example, both of which require a governance layer and a deep understanding of the process.

Directions on Microsoft's research director Rob Helm said that both SOA and the cloud determine which major components are reusable and which technologies are suitable for running large components on open networks. He points out that an organization that leverages SOA in a modular way can better migrate modules to the cloud.

WSO2 CEO Sanjiva Weerawarana, an open source SOA software vendor, says the cloud can be a good way to deploy services in an SOA environment. He points out that SOA and cloud can complement each other, but they are not based on the same idea: "Cloud computing is a deployment architecture, and SOA is how the enterprise IT architecture is structured." ”

"SOA can help cloud applications integrate into legacy systems," says Lew Tucker, chief technology officer for cloud computing at Sun Microsystems. Sun prepares to unveil its cloud plan by March 18. ）

Will the cloud suffer the same decline as SOA?

Another common denominator of SOA and cloud is the constant piling up of terminology, Hall says. He pointed out that "after the exaggerated stage is the disillusionment stage" SOA is the case. Since then, people's understanding and use of this technology will be more realistic.
