A public cloud service provider is facing several challenges in its IT operations:
1 - Rapidly increasing storage capacity needs, forcing frequent data migrations
2 - Consolidation of disparate Fibre Channel fabrics from multiple connectivity vendors
3 - Deployment of several types of hypervisors simultaneously in production
4 - Long-term archival of very large volumes of tenant data for compliance
5 - Very limited application mobility across data centers, using array-based replication
Which challenge(s) would VPLEX address?
Refer to Scenario 1 below.
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult
What can the IT department do to address problem (a)?
Refer to Scenario 3.
A US company has deployed web services within a private cloud. They wish to provide additional web services elastically and distribute them around the globe using a public cloud provider.
The web services have a dependency on a database resource in the private cloud. The web services are deployed through a service catalog as a standardized service offering, which includes an intrusion prevention system that periodically polls a central management server for security updates. The IPS management server is located within the private cloud.
The web services collect highly regulated personal health information about consumers who are located around the world.
What would be the best solution for protecting the personal health information collected in the web service?
In an effort to grow market share, a financial company has decided to expand their portfolio of web-based services to residential and mobile users. To improve adoption of these services, the software development team was given the requirement to encrypt data in flight without requiring a software footprint on the client.
Which capability best meets their in-flight encryption requirement?
