Cost is an important factor to any company as public clouds mostly offer a pay-as-you-go service, allowing for actions such as intermediate expansion during traffic spikes or disabling testing environments to achieve a TCO (total cost ownership) and maximize the ROI (return on investment).
Reliability should be the focal point of every corporation’s needs as offloading the responsibility of managing and maintaining dedicated hardware can help revoke the need to employ expensive engineers to achieve a goal that has already been undertaken and fulfilled by a company that specializes in such services. Let them worry about faulty hardware and apply your efforts to the areas that you know best.
Public cloud providers can deliver an assortment of preconfigured aids to achieve some necessary technical tasks such as load balancing, automatic failover, and auto-scaling. Having these services readily available removes the need to adopt the time-consuming development of engineering such practices.
