Rolling release development models are one of many types of software release life cycles.Although a rolling release model can be used in the development of any piece or collection of software, it is most often seen in use by Linux distributions, notable examples being GNU Guix System, Arch Linux, Gentoo Linux, openSUSE Tumbleweed, PCLinuxOS, Solus, SparkyLinux, and Void Linux.
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public.
LTS applies the tenets of reliability engineering to the software development process and software release life cycle.Long-term support extends the period of software maintenance; it also alters the type and frequency of software updates to reduce the risk, expense, and disruption of software deployment, while promoting the dependability of the software.
A canary release (or canary launch or canary deployment) allows developers to have features incrementally tested by a small set of developers. Feature flags like an alternate way to do canary launches [ 7 ] and allow targeting by geographic locations or even user attributes. [ 8 ]
Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
In software deployment, an environment or tier is a computer system or set of systems in which a computer program or software component is deployed and executed. In simple cases, such as developing and immediately executing a program on the same machine, there may be a single environment, but in industrial use, the development environment (where changes are originally made) and production ...
[1] [2] It aims at building, testing, and releasing software with greater speed and frequency. The approach helps reduce the cost, time, [citation needed] and risk of delivering changes by allowing for more incremental updates to applications in production. A straightforward and repeatable deployment process is important for continuous delivery.
