Moving to the cloud is not a single step, but a journey.
TechNet UC is practiced at leading organizations of all sizes through
the pitfalls of this journey and can point out interesting features
(best practices) along the way. Migrating an On-Premise SharePoint
Infrastructure to SharePoint Online, or implementing SalesForce,
or any other SaaS application is a perfect example of this.

Any Infrastructure as a Service (IaaS), Software as a Service (SaaS),
or Platform as a Service (PaaS) workload has to be planned, designed,
implemented, managed, and eventually replaced as part of the lifecycle
of technology. Managed Cloud Services includes infrastructure and
application-level support.

TechNet UC offers a full set of Managed Services features, such as
monitoring and reporting, addschangesdeletes, troubleshooting
and remediation and even lifecycle management.

IaaS is a flexible cloud computing service that allows businesses to
pay for what you use based on increasing and decreasing demand.
It helps businesses avoid the expense and complexity of buying and
managing your own physical servers and other datacenter
infrastructure. Each resource is offered as a separate service
component, and you only need to rent a particular one for as long
as you need it.
