What Does High Availability Mean

Auth0 is a "status as a service" start-up company, but also a heavy cloud service users. For them, service outages mean that a lot of user-managed applications cannot log in, so availability is critical to them. Recently, Auth0 Engineering director Jose Romaniello shared a cloudy architecture that they could exempt across providers from a wide range of Microsoft Azure downtime. Auth0 is a "status as a service" start-up company that allows users to ignore the underlying infrastructure for mobile ...

This article was translated by Wang Xiuli Jiangnan University Graduate School of Design, authors: Sabina Idler, only to see the original learning, declined to reprint. In recent years we have carefully studied child-centered design. The main reason for the study is to create awareness for the target group of children's designers. Adult designers are not able to design games, web pages, and applications for kids without the participation of targeted age groups. Of course, the experience of adults is complicated, and we always go to add some colors and dolls, while simplifying the interaction process, but these do not make it ...

"Guide" the author (Xu Peng) to see Spark source of time is not long, note the original intention is just to not forget later. In the process of reading the source code is a very simple mode of thinking, is to strive to find a major thread through the overall situation. In my opinion, the clue in Spark is that if the data is processed in a distributed computing environment, it is efficient and reliable. After a certain understanding of the internal implementation of spark, of course, I hope to apply it to practical engineering practice, this time will face many new challenges, such as the selection of which as a data warehouse, HB ...

"Editor's note" in the cloud computing ecosystem, there are two types of users that need to use cloud computing resources: the traditional (traditional IT applications) and the emerging Cloud computing Application (Cloud-aware applications) in the Internet tide. A popular metaphor abroad is that in the traditional service mode, it can be imagined that the server is the IT pet (Pets), give them name, carefully raised, when they are sick, you have to repair them; in the new form of application service model, virtual machine ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...
