Since the music 2012 into the television industry, has been in constant sales based on the "platform + content + Terminal + Application" of the ecological concept, this year, music video TV is by virtue of their own sales mall, hoping to get through from manufacturing to sales of the whole industry chain solutions. This is not, le View TV has just announced recently: "Materialize fans festival" the same day Le View Mall Super TV sales 100,000 units, accessories over 40,000 pieces, the total sales amount of 400 million yuan, the total number of participants more than 8 million. From the data alone, le see already by virtue of their own mall completed by the "pre-sale" to the "sale" ...

The O2O system should be based on the O2O of the fans rather than the o2o! of the products. Now the mobile phone has entered the so-called 020 era, the most typical is Wang O2o, he wants to through the offline integration of the customer's aggregation, in turn to increase his shopping volume, through the experience to create his more customer aggregation. Is this right? But I think this way of thinking should still stay in the electricity quotient 1.0 times, or he forgot the entire mobile Electricity Business Foundation, the mobile electricity merchant most important foundation, the life is bigger than the business. So the essence of O2O is not the O2O of the product.

Zhioyuan reliability is one of the typical characteristics of cloud service based on the test point technology. In the cloud computing environment, a cloud service reliability measurement model based on the checkpoint rollback strategy is proposed, which aims at the problem of the system service reliability change due to the failure failure of the virtual Machine Task compute node in cloud service system, and based on the checkpoint rollback strategy, the cloud service reliability measurement model is established. The correctness of the measurement model is proved by theoretical deduction, and it is proved that the service reliability can be optimized when the test point setting time increases according to certain exponential value. Key words: Cloud ...
