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 4.
A construction firm with a substantially virtualized IT infrastructure wishes to consider cloud
enablement next, as part of its logical progression to ITaaS.
As a first step, the firm plans to transition one relatively low-risk service -- daily backup -- to a public CSP. The existing backup strategy involves array-based cloning, followed by backup of the clones with dedicated servers. The system is functional; however, since the backup target device is due for a technology refresh, the firm is open to alternatives.
In evaluating alternatives, the key consideration is the ability to meet backup windows for daily incremental backups during the work week.
As advisor to this firm, you have conducted a quick assessment of the candidate applications and storage involved in daily backups. Relevant details are presented in the exhibit.
Another evaluation point is the completion time for weekly full backups to the cloud service provider. Which would have the most favorable impact on full backup speed?
Refer to the exhibit.
A company is evaluating an ITaaS architecture to provision applications for their various business units. The IT architects consult you for help on the illustrated design.
What is a characteristic of this design?
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)?
