In the information age, teachers are not the only source of information. The traditional teaching method brings problems such as passive learning and low interest in learning. This paper is aimed at studying how to analyze and study the hybrid teaching of English online and offline based on cloud collaboration and describing edge computing. This paper proposes the problem of mixed teaching of English online and offline. This question builds on the fundamentals of cloud collaboration. Therefore, the concept and related algorithms are expounded, and the case design and analysis of blended teaching are carried out. The experimental results show that in the follow-up questionnaire survey, online and offline blended teaching is applied to teaching practice. This brings the average academic performance of college English courses to 4.03. Compared with the previous academic performance, there has been obvious progress and improvement.

While the Domain Name System (DNS) is an infrastructure of the current network, it still faces the problem of centralization and data authentication according to its concept and practice. Decentralized storage of domain names and user local verification using blockchain may be effective solutions. However, since the blockchain is an add-only type database, domain name changes will cause out of date records to still be correct when using the Simplified Payment Verification (SPV) mechanism locally. This paper mainly introduces Local Enhanced Authentication DNS (LEA-DNS), which allows domain names to be stored in public blockchain database to provide decentralization feature and is compatible with the existing DNS. It achieves the validity and timeliness of local domain name resolution results to ensure correct and up to date with the Merkle Mountain Range and RSA accumulator technologies. Experiments show that less than 3.052Kb is needed for each DNS request to be validated, while the validation time is negligible, and only 9.44Kb of data need to be stored locally by the web client. Its compatibility with the existing DNS system and the lightness of the validation protocols indicate that this is a system suitable for deployment widely.

“…Besides this basic concept, clouds from different operators might cooperate not only to scale resources for handling short-term spikes but also to provide adequate responsiveness and usability to clients distributed worldwide [1]. Hence, several solutions have been proposed to deploy cross-cloud cooperative architectures, for instance, Federated clouds [2], Joint-cloud [3], and Edge federation [4].…”

Virtual Machine (VM) migration presents several advantages for both cloud operators and cloud users. The benefits of VM migration are amplified in the context of Jointclouds, in which multiple clouds owned by distinct operators exchange VMs. However, inter-cloud VM migrations might require the usage of the Internet, which creates the possibility of external threats and therefore, a risk to the VMs' integrity. Thus, we propose a novel approach to secure VM migration for Joint-clouds. We consider both local migration and inter-cloud migration. Our solution is based on a multi-blockchain system, in which each cloud provider participates in the maintenance of a consortium blockchain to store relevant information about the migrations. In addition, each cloud operator might choose to keep a local blockchain to secure its local VM migrations. Therefore, inter-blockchain communication plays an important role in our work.
