Container management frameworks, such as Docker, package diverse applications and their complex dependencies in self-contained images, which facilitates application deployment, distribution, sharing. Currently, Docker employs a shared-nothing storage architecture, i.e. every Docker-enabled host requires its own copy of an image on local to create run containers. This greatly inflates utilization, network load, job completion times the cluster. In this paper, we investigate option storing...

Docker containers have become a prominent solution for supporting modern enterprise applications due to the highly desirable features of isolation, low overhead, and efficient packaging execution environment. Containers are created from images which shared between users via registry. The amount data registries store is massive; example, Hub, popular public registry, stores at least half million images. In this paper, we analyze over 167 TB uncompressed Hub images, characterize them using...

Nowadays, Cloud providers revise the terms of their Service Level Agreements (SLAs) to include security provisions due criticality for customers. In order speed up adoption by service and consumers make them more actionable, SLAs monitoring should be described in a machine-processable, agile extensible way. Several tools SLA management are available on market but most deal with performance metrics do not refer properties. There other cloud security, non-SLA However, they associated systems....

Managing service quality in heterogeneous Cloud environments is complex: different providers expose management interfaces. To manage Service Level Agreements (SLAs) this context, we have developed the rSLA framework that enables fast setup of SLA monitoring dynamic and environments. The made up three main components: language to formally represent SLAs, Service, which interprets SLAs implements behavior specified them, a set Xlets - lightweight, dynamically bound adapters controlling In...

Due to their tight isolation, low overhead, and efficient packaging of the execution environment, Docker containers have become a prominent solution for deploying modern applications.
