= Guide to open source development in the cloud!
|
|
|
|
|
|
An https://developer.ibm.com/blogs/oreilly-open-source-skill-survey-blog/[O’Reilly survey^], commissioned by IBM in Fall 2020, pointed out that, when choosing cloud providers, 70% of respondents prefer one based on open source. The survey went on to say:
|
|
|
|
TIP: Developers who want to develop cloud applications should work on honing their open source skills, which underly every major cloud platform, instead of only focusing on building skills for a proprietary cloud.
|
|
|
|
The most desirable open source skills are those related to *Linux (containers)*, *artificial intelligence* and *machine learning*, and *data storage.*
|
|
|
|
This goals of this guide(https://open-cloud-guide.dev/[Text^] by IBM / Apache Licensed, 2021) are to provide:
|
|
|
|
* Comprehensive learning for hybrid cloud and multicloud developers.
|
|
* A cloud-neutral view of how various clouds are using open source in their offerings.

TIP: Why Open Source!
|
|
|

|
|
Open source refers to an *openly distributed* program code (including codes that are *free of charge*) that can be *utilized* and *modified* by the end user *without restriction.*

|
|
====
|
|
Singularity can be used with Docker images. This feature was included because developers use and really like using Docker and scientists have already put much resources into creating Docker images.
|
|
|
|
Features:
|
|
|
|
* Use a Docker image instantly as a Singularity image
|
|
* Pull a Docker image
|
|
* Build images with bases from assembled Docker layers

*etcd vs. Redis*
|
|
|
|
Like etcd, Redis is an open source tool, but their basic functionalities are different.
|
|
|
|
[cols="1,1"]
|
|
|===
|
|
|Redis|etcd
|
|
|
|
| Redis is an in-memory data store and can function as a database, cache, or message broker. Redis supports a wider variety of data types and structures than etcd and has much faster read/write performance.
|
|
| etcd has superior fault tolerance, stronger failover and continuous data availability capabilities.
|
|
|
|
|Redis is better suited for serving as a distributed memory caching system than for storing and distributed system configuration information.
|
|
|etcd persists all stored data to disk.
