RetroVisor: Nested Virtualization for Multi IaaS VM Availability
نویسندگان
چکیده
Nested virtualization [1] provides an extra layer of virtualization to enhance security with fairly reasonable performance impact. Usercentric vision of cloud computing gives a high-level of control on the whole infrastructure [2], such as untrusted dom0 [3, 4]. This paper introduces RetroVisor, a security architecture to seamlessly run a virtual machine (VM) on multiple hypervisors simultaneously. We argue that this approach delivers high-availability and provides strong guarantees on multi IaaS infrastructures. The user can perform detection and remediation against potential hypervisors weaknesses, unexpected behaviors and exploits.

Managing Risk in a Derivative IaaS Cloud
Infrastructure-as-a-Service (IaaS) cloud platforms rent computing resources with different cost and availability tradeoffs. For example, users may acquire virtual machines (VMs) in the spot market that are cheap, but can be unilaterally terminated by the cloud operator. Because of this revocation risk, spot servers have been conventionally used for delay and risk tolerant batch jobs. In this pa...
متن کاملMulti-Hypervisor Virtual Machines: Enabling an Ecosystem of Hypervisor-level Services
Public cloud software marketplaces already offer users a wealth of choice in operating systems, database management systems, financial software, and virtual networking, all deployable and configurable at the click of a button. Unfortunately, this level of customization has not extended to emerging hypervisor-level services, partly because traditional virtual machines (VMs) are fully controlled ...
متن کاملHVX: Virtualizing the Cloud
Nowadays there is significant diversity in Infrastructure as a Service (IaaS) clouds. The differences span from virtualization technology and hypervisors, through storage and network configuration, to the cloud management APIs. These differences make migration of a VM (or a set of VMs) from a private cloud into a public cloud, or between different public clouds, complicated or even impractical ...

These days everything is shifting to cloud computing. Two of the major types of clouds are infrastructure as a service (IAAS) & Platform as a service (PAAS) cloud. Network engineers and administrators make use of IAAS instead of physical hardware for implementing servers. Software Developers use PAAS for programming purposes. Virtualization is the main base for implementing cloud computing. The...
متن کاملInception: Towards a Nested Cloud Architecture
Despite the increasing popularity of Infrastructure-as-aservice (IaaS) clouds, providers have been very slow in adopting a large number of innovative technologies, such as live VM migration, dynamic resource management, and VM replication. In this paper, we argue that the reasons are not only technical but also fundamental, due to lack of transparency and conflict of interest between providers ...
