IaC grew as a response to the difficulty posed by utility computing and second-generation web frameworks. In 2006, the launch of Amazon Web Services’ Elastic Compute Cloud and the 1.0 version of Ruby on Rails just months before [2] created widespread scaling difficulties in the enterprise that were previously experienced only at large, multi-national companies. [3]
A bucket can be configured to save HTTP log information to a sibling bucket; this can be used in data mining operations. [14] There are various User Mode File System (FUSE)–based file systems for Unix-like operating systems (for example, Linux) that can be used to mount an S3 bucket as a file
Amazon experiences an outage of S3 in us-east-1. [289] There are also related outages for other services in us-east-1 including CloudFormation, autoscaling, Elastic MapReduce, Simple Email Service, and Simple Workflow Service. A number of websites and services using S3, such as Medium, Slack, Imgur and Trello, are affected. AWS's own status ...
These log messages can then be used to monitor and understand the operation of the system, to debug problems, or during an audit. Logging is particularly important in multi-user software, to have a central overview of the operation of the system. In the simplest case, messages are written to a file, called a log file. [1]
The earliest known work (1989) on continuous integration was the Infuse environment developed by G. E. Kaiser, D. E. Perry, and W. M. Schell. [4]In 1994, Grady Booch used the phrase continuous integration in Object-Oriented Analysis and Design with Applications (2nd edition) [5] to explain how, when developing using micro processes, "internal releases represent a sort of continuous integration ...
The most appropriate approach to reconciliation depends on the application. A widespread approach is "last writer wins". [1] Another is to invoke a user-specified conflict handler. [4] Timestamps and vector clocks are often used to detect concurrency between updates. Some people use "first writer wins" in situations where "last writer wins" is ...
[1] A write ahead log is an append-only auxiliary disk-resident structure used for crash and transaction recovery. The changes are first recorded in the log, which must be written to stable storage, before the changes are written to the database. [2] The main functionality of a write-ahead log can be summarized as: [3]
Object storage (also known as object-based storage [1] or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks.
