Scenario 7.
A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%.
-- Exhibit -
To test the functionality of the new infrastructure, a load simulator is used to increase utilization on the servers. At 80% utilization, the orchestration tools provision the required resources in the public cloud. However, the utilization on the private cloud resources continues to increase, while the utilization on the public cloud resources remains at 0%.
What is the most likely cause of this problem?
A public cloud service provider is facing several challenges in its IT operations:
1 - Rapidly increasing storage capacity needs, forcing frequent data migrations
2 - Transition to a converged network infrastructure with FCoE
3 - Deployment of several types of hypervisors simultaneously in production
4 - Long-term archival of very large volumes of tenant data for compliance
5 - In-flight encryption for tenants with stringent compliance requirements
Which challenge(s) would VPLEX address?
Refer to Scenario 5.
Refer to the exhibit.
An innovative high-end graphics and multimedia 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.
-- Exhibit -
Your second goal is to demonstrate that the CSP solution will be suitable for even the most time consuming backups.
Which application would you select for this test?
You are a cloud consultant recently assigned to help an international pharmaceutical manufacturer implement ITaaS. The company has a well-staffed, highly technical IT organization.
There are concerns that implementing ITaaS will be met with resistance, because the IT group may feel that their job security is threatened.
You are seeking an individual within the organization to fill the role of Executive Sponsor for the ITaaS transformation project. Which individual would be the best candidate to fill this role?
A marketing company is using a Customer Relationship Management SaaS. The SaaS provider has deployed hardware load balancers to distribute users between application servers. User login states are preserved in the load balancer. Subsequent login requests direct each user to the same application server. If the server is unavailable or too busy, the user cannot log on.
Although the company is very happy with the SaaS cost savings they are unhappy with application availability. To improve application scalability the SaaS provider added new servers to the environment. Users, however, are still experiencing the same problem.
Which service characteristic should the SaaS provider implement to improve the user log-on reliability and scale application performance?
