\noindent Today, more and more people rely on IaaS
|
|
|
|
|
(Infrastructure-as-a-Service) services over a traditional on-premise
|
|
|
|
|
infrastructure to provide computational support to applications, services and
|
|
|
|
|
business processes. This is due to the fact that the costs of an organization
|
|
|
|
|
or business are reduced, since there is no need for an upfront investment on
|
|
|
|
|
the purchase of equipment. Also, the operational cost of using IaaS services is
|
|
|
|
|
based on flexible billing models according to the usage (of the offered
|
|
|
|
|
infrastructure resources). In addition, it is possible to scale the offered
|
|
|
|
|
remote infrastructure, depending on the needs of the organization and the
|
|
|
|
|
current workload of the services and applications to be supported. In this way,
|
|
|
|
|
the responsibility for the equipment and its maintenance is transferred to
|
|
|
|
|
third parties, while at the same time a new trust model is introduced between
|
|
|
|
|
the user/organization and the cloud provider. The increased interest shown by
|
|
|
|
|
enterprises when in comes to virtualization technologies (which are a key
|
|
|
|
|
foundation of IaaS services) in conjunction with the rapid rise in popularity
|
|
|
|
|
of container technologies such as Docker, has in turn begun to drive the
|
|
|
|
|
adoption of the microservices architecture for application development. An
|
|
|
|
|
architecture based on virtualization technologies for hosting applications in
|
|
|
|
|
cloud infrastructures and container technologies for partitioning their
|
|
|
|
|
functions into a set of containers and thus, providing an appropriate level of
|
|
|
|
|
performance and scalability \cite{awsMicroservices}. However, such applications

remain vulnerable to security issues that may be tied to the cloud and/or the
