Cloud security remains a headache for program developers

At the Zendcon conference, Amazon, IBM, and Rackspace company representatives discussed the cloud security and its availability, as well as the use of SQL and database connections.

As early as a few years ago, security was the most discussed issue when cloud computing began to emerge, and security is still the most vexing issue for developers, the IBM spokesman stressed.

at the Zendcon conference in California, IBM and Amazon executives discussed the security issues associated with cloud computing. IBM Distinguished Engineer Mac Devine says that transitioning from a dedicated facility to a shared environment in cloud computing means that developers must have enough security in their applications that developers should not think that public cloud providers can protect data security, he warns: "You can't say that, ' well, No one can cross my firewall '. '

Shared environment poses risks

"You should think about things from a different perspective, which is a shared environment," he says. "The cloud environment brings collaboration and risks." "

But cloud vendor Amazon's senior Network service engineer, Jeff Barr, retorted," I agree that we should worry about security, but you also have to realize that many cloud environments can provide a safe and efficient infrastructure, and, conversely, What developers need to worry about is application-level security issues. "

Barr claims that security and availability are two of Amazon's top priorities, and that Amazon has security certificates such as ISO 27001 and SAS 70, adding that large cloud providers can invest heavily in long-term security, This may not be possible for other vendors. Devine points out that cloud infrastructure providers can provide compliance and business security, and in some cases the cloud environment is even more secure than the enterprise onsite system.

Causes bottlenecks to row data

Participants also explored the use of SQL and database connections in cloud computing. SQL "As a storage design pattern is not an ideal choice for cloud applications," says Adrian Otto, senior technology strategist at Rackspace Cloud, who later described SQL as the "number one bottleneck" of the cloud's environmental resilience, by using this flexibility, Applications can use more or fewer application servers as needed. Otto suggests that developers who want to take advantage of this flexibility should build a decentralized data model that is measured horizontally from a horizontal scale. "SQL is not a problem in itself, the problem is row-oriented data in the application, which creates a performance bottleneck," Otto said.

Developers should not"You should think that these resources are basically transient and replaceable in a cloud environment," Barr said, putting personal resources into the cloud. "One participant also raised the issue of I/O inconsistency in the cloud environment, and Barr did not make a clear response, but hinted that Amazon was trying to solve the problem," we are trying to make things better.
