Topic 6, Contoso, LTD 2
Contoso, Ltd. is a Canadian business law firm that currently employs 300 people. The company operates a main office in Vancouver that houses 250 employees and a branch office in Seattle that houses 50 employees. All Contoso users are Skype for Business-enabled. Contoso is launching a hybrid configuration of Office 365 to validate the cloud-based Exchange Online service.
Contoso plans to introduce a remote disaster recovery data center to host remote replicas of key services, including Active Directory Domain Services (AD DS), Skype for Business, Exchange, and files and legal software. The company also plans to acquire a small law firm in Vancouver called Litware, Inc., which has 80 employees. Litware currently uses a 10-megabit per second (Mbps) Internet connection.
Half of Litware employees will use Skype for Business services. All Skype for Business-enabled users in Litware will use Instant Messaging only. Currently, Instant Messaging concurrent usage at Litware is 50 percent during peak hours.
There is a possibility that Contoso will make two more acquisitions during the next three years. Vancouver and Seattle employees have submitted support tickets to report poor quality of outbound Skype for Business calls to external users. A user activity report collected by the help desk department is shown in the User Activity Report section.
There is a concern that in the future, the volume of Skype for Business traffic may reach up to 50 percent of the current bandwidth available in the Vancouver office.
