IBM Cloud Computing News - Manage transactions in the cloud, Part 1: Transaction basics and distributed transactions

[IT News Bot]

In this first part of a two-part series, André Fachat discusses
transaction basics and distributed transactions. Transactions can make error
handling easy, not just with a single resource but also across resources.
Here, André shows you how two-phase commit distributed transactions work and
points out that even they are only "eventually consistent," if only by a small
time interval. He also illustrates how a persistent transaction log in the
transaction manager is a requirement for distributed transactions.
