You are responsible for proprietary email and collaboration services for a small company, and the lease for the current environment expires soon. The company typically has about fifty employees, but this number doubles during peak holiday season.
During this peak season, the current environment had performance issues that negatively impacted the ability to book orders. The CEO asks you, the cloud architect, to consider the pros and cons and make a recommendation to either refresh the current environment or transition to a SaaS based email and collaboration environment.
In priority order, the CEO presents the following requirements for an email and collaboration solution:
1 - Minimize CAPEX
2 - Provide more consistent performance, particularly during peak season
3 - Be able to easily handle fluctuations in the workforce
4 - Maintain SLAs that are comparable to the internal business as seen today
5 - Minimize the impact on users to install new releases and service packs
6 - Have a flexible exit strategy
Based on the requirements and priorities, you find and recommend a particular hosted email solution.
