Cloud services: Exploiting advantages and recognizing risks
The use of services in the cloud comes with many advantages. You do not have to install and maintain your own servers, and there is no need for major investments, since billing is carried out per user, per month or according to intensity of use. Once the necessary preparations have been made regarding identities and authentication, the client can be distributed, the users can be instructed, and then the use of the service can begin.
However, the risks are often overlooked, because a cloud service poses completely different challenges for the transmission networks compared to local services. In the LAN, we are talking about gigabit bandwidths, latencies in the single-digit millisecond range and dedicated connections. With cloud services, the distance between client and service is much greater, and accordingly, longer latency times must be considered. But your firewall, Internet connection, name resolution and other components also face many new challenges, which you should review before implementing a new cloud solution.
A network assessment clarifies and defines the requirements and ensures that no nasty surprises await in later operation. Do you want to take the risk of having to stop a rollout of a new application because it doesn’t work after all, or that additional data volumes will affect other services and, in the worst case, make them unusable?
