A colocation facility is the most suitable option for the company's scenario because it allows the company to rent space for servers and other computing hardware in a third-party datacenter. The company gets the benefits of a datacenter, such as enhanced security and bandwidth, without the hefty initial investment of building its own. It also retains control over the hardware and infrastructure, unlike with cloud services. A branch office solution typically does not include significant IT infrastructure and might not improve application performance. Building an on-premises datacenter offers control but comes with high setup costs, which the company is trying to avoid.
