heartbeat1.x and 2.0.x version of the structure is very simple, each module is concentrated in the heartbeat, to the 3.0 version, the entire Heartbeat project was split, divided into different projects to develop separately.
heartbeat2.0.x Previous versions have modules:
Heartbeat: Communication detection module between nodes
HA-LOGD: Cluster Event Log service
Java.sql.Connection. Valid values are: transaction_read_uncommitted, transaction_read_committed, Transaction_repeatable_read, TRANSACTION_ SERIALIZABLE and Transaction_none

server-hosted data center. Network devices must be used for different data centers. To make more profits and open the price distance from telecom data centers, private data centers will never reach the telecom level. For example, a private data center does not have enough bandwidth, no bandwidth monitoring, no high-end hardware devices, or even no backup power. The cost determines the price, which is why many server vendors advocate low prices. We ho

L consider software as a service
In order to transform from providing internal deployment software to software as a service, software vendors should change their thinking in three interrelated fields: business model and application architecture; the third is the operation structure.

In the EJB 2.1 specification, entity beans were very "heavyweight" and dependent on the application server and the entire Java EE runtime environment. in Java Persistence, entity beans are regular Java objects that are managed by a persistence service. unlike their EJB 2.1 counterparts, entities in Java Persistence are not required to implement any special spec-defined interfaces or classes. another weakness of the older specification was that it left individual

Cloud computing is the most fashionable word nowadays. It not only brings about technological changes, but also changes in business models. Not only did Google, IBM, Microsoft, sun, and other IT giants flock together, as did a group of smaller companies. Undoubtedly, cloud computing will be the direction of next-generation Internet technology. Different vendors provide different definitions of cloud computing based on their own advantages and interest
