Cloud migration is a topic of great relevance for at least a couple of years and there are now many companies of various types and sizes that offer this type of service.
There is a wide range of proposals designed to migrate data and cloud applications, varying depending on the type of specific service and the size of the operators: from large public or hybrid cloud providers to smaller and specialized service providers offering targeted managed services. However, everyone has in common a multi-tenant infrastructure with access based on Internet connectivity.
Distributed Denial of Service (DDoS), unfortunately, is a rampant problem for companies offering cloud and hosting services due to their rapid expansion in terms of scale and frequency.
A single attack can affect only one application within an environment, but by doing so, if it has enough power, the attack can saturate Internet connectivity and affect all services that share the same Internet access. The phenomenon has been described in the Arbor Networks Worldwide Infrastructure Security Report (WISR), which highlights the following:
1) 61% of data center or cloud operators suffered attacks that completely saturate their band in 2016;
21% of data center or cloud operators suffered over 50 DDoS attacks per month.
It is therefore more pressing for cloud service providers and for their customers to implement adequate availability protection measures.
