Azure was announced on April 9, March (II) and azure was announced on April 9, March Azure was released in March: HDInsight's Apache Hadoop and ExpressRoute ultra-high-performance gateway layer were officially released, and SQL Database Premium RS layer was released in public preview version. Azure HDInsight runs on Apache Hadoop in Linux and is officially released Apache Hadoop is now officially released. You can select a Linux cluster when deploying a workload. Now, you can more easily transf

itself. The data synchronization method adopts the MySQL replication technology. MySQL replication pulls a binary log file from the server to the master server, and then parses the log file into the corresponding SQL statement to re-execute the operations on the slave server, this method ensures data consistency. In order to achieve higher availability, MySQL replication technology and high availability cluster software keepalived are generally used to achieve automatic failover in actual appli

Service levelMicrosoft Azure Redis Cache is divided into two levels:(1) Base (basic)-a single node. Available in different sizes. There is no SLA for the basic mode.(2) standard-Two-nod

These meanings actually correspond to different levels of technology. For example, "swap" emphasizes hardware, meaning that network nodes are made up of large capacity, non-blocking and transparent optical cross connection (OXC) devices; "Smart" emphasizes distributed control, including automatic

paths and dedicated resources to achieve load balancing. A network with traffic engineering can be implemented using connection-oriented technologies, such as ATM and frame relay. However, networks that mix multiple technologies need to be managed by their respective network management systems, causing great inconvenience in operations.A pure IP network can implement traffic engineering based on the MPLS protocol, and obtain benefits by providing different services and controllable networks.

infrastructure will also increase. The pilot has become a more attractive choice than ordinary switches. High Availability of the Guide High Availability is another design feature of the Guide. Usually, the pilot is deployed in a critical business environment, which uses a high normal running time as one of the key criteria of SLA. Generally, the guide is equipped with redundant components to avoid spof. This includes the most basic hot swapping powe

Many of our ideas have changed in the form of mutual integration between the Internet and communication networks. With the advent of the IPv6 era, communication network protocols will change. In this context, we propose the Mobile IPv6 protocol. QoS in a mobile IP address is much more complex than that in a fixed IP address. The following problems exist in the use of Differentiated Services for Mobile IP addresses: ◆ Differentiated Services are suitable for well-designed networks with reasonable

aspects of Java application performance are stability and reliability. Under SLA umbrella with 99.9% typical available targets, stability and reliability are particularly important for program operations. These systems should have a high level of fault tolerance and a rigorous budget for applications and resources to prevent the multi-meter effect. This approach prevents some of these situations, such as the use of all available physical, middleware,
