Last week, we described how to evaluate the code used to extend cloud applications. Now, we're going to look at the coding and system-change strategies that are likely to make the system more vulnerable over time. Because of the seemingly never-ending development requirements of the CRM system, the durability of our code will be a key factor in the long-term smooth running of these systems. But before I begin, I need to declare that the usages and terms I cite apply only to the salesforce.com environment, and that other applications and platforms use different types of association ...

The emergence of CRM, changed the past customer data dispersed, customer management complex and cumbersome situation, but also to enable enterprises to customer data, product information, employee data to achieve a unified. Since the 1990s, CRM's management concept and operation system have been rapidly accepted by the business community and widely used in large enterprises, but how to apply CRM effectively is a very important research topic for the small and medium-sized enterprises that account for more than 90% of the total enterprise. This is not only because of the large number of small and medium-sized enterprises, the national economy has a significant impact, but also because this is the survival and development of SMEs within ...

A fast real-time migration method for virtual machines in cloud computing environment Pegasus, Feng, Li Zhui. In this paper, a fast real time migration method of virtual machine is proposed for the long time migration of virtual machines in cloud computing data center. By formulaic description and performance analysis of the pre copy model, the page bitmap used to mark the changed pages of memory is added in the pre-copy method. During the migration process, the frequently changed memory pages are judged, and the pages that have changed frequently are marked in the new page bitmap and transmitted only in the last iteration. Experimental results show that with the traditional pre-handcuff ...

Research on data access control method in cloud computing Nanjing University of Posts and telecommunications This paper proposes an attribute-based access control model (DACC) for cloud computing environment using CP-ABE encryption algorithm. The core idea is to use the AES symmetric encryption algorithm and the Cp-abe encryption algorithm, respectively to encrypt the data and symmetric key, and the user of the attribute matching to decrypt the key cipher text and the data cipher in sequence. In order to reduce the cost of storing and updating keys, the Key Distribution center KDC is introduced to manage attributes and keys. Cloud computing Service Provider ...

Research on ciphertext search technology in cloud environment Beijing, Beijing, China posts a new and efficient method for searching public key Cryptography (Nscf-peck) is proposed in this paper. The scheme is based on bilinear pair structure and uses public channel to transmit ciphertext. In the design of the whole algorithm, only two times bilinear pair operation is used, which greatly reduces the computational expenditure of the searchable public key cryptography. Meanwhile, using public channel to transmit encrypted data between client and cloud server reduces the cost of constructing secure channel. Finally, this paper proves that nscf-pec ...

As companies continue to accelerate the pace of cloud technology, using new technologies such as infrastructure, Service (IaaS) or software as a service (SaaS), the need for solutions to secure access and reliable operations in the cloud architecture is becoming increasingly evident. It now appears that, as enterprise data is kept in different devices, which are provided by different providers or partners, the enterprise must monitor and protect the new "security boundaries". Similarly, carefully weighing how to protect cloud-based data should be incorporated into the enterprise's context as part of the overall security strategy for the enterprise. and protect ...
