- Intercloud Architecture and Technologies
- Sep 26, 2016
In this sample chapter from Intercloud: Solving Interoperability and Communication in a Cloud of Clouds, authors Jazib Frahim, Venkata Josyula, Monique Morrow, and Ken Owens explore how cloud providers have set up data centers at many locations to service their customers. For example, Amazon, Google, Microsoft, Salesforce.com, and others have established data centers for hosting cloud application services such as social networking, gaming portals, and business applications. In many of these social
networks, the service components run in separate virtual machines that may be hosted in data centers owned by different cloud computing providers. In order to link the services provided by different providers at different locations around the world and to provide quality service to a consumer, it is necessary to build an Intercloud to bring the services together. This chapter details Intercloud architecture mode, Intercloud use cases, and Intercloud deploy.

- Responding to Real-World Cyber Threats
- Feb 16, 2016
- Are you ready to take on the latest cyber threats? Research shows that many organizations are not, because they're unprepared for what happens when common defenses fail to prevent a breach. Joseph Muniz, co-author of Security Operations Center: Building, Operating, and Maintaining Your SOC, explains how to build a security strategy around the assumption that your defenses WILL fail. By implementing this approach, your organization can shorten the time of exposure when you're compromised, limiting losses from a breach. Without this type of visibility, you probably won't know that you're compromised until the damage is already done.
