本篇文章是一個工具分享文，探討如何使用 Vagrant 來架設一個 ceph 叢集環境來測試與開發。

Ceph 是非常知名的分散式儲存的解決方案，其提供 Object, block 以及 file 等儲存空間供不同需求的應用程式使用
Ceph 本身是由多個不同的組成元件所組成，這也是為什麼會稱 Ceph 叢集的概念，元件包含
1. Monitors(MON)
2. Managers(MGR)
3. Metadata Servers(MDS)
4. Object Storage Devices(OSD)

CNCF 畢業專案 Rook 則是一個將 Ceph 與 Kubernetes 整合的解決方案，其簡化了部署 Ceph 的複雜度，讓使用者可以更輕鬆的透過 Kubernetes 去部署一套 Ceph 叢集環境來測試與開發。
不過並不是所有使用 Ceph 的環境都會搭配使用 Kubernetes，作者觀察到目前網路上至少有七種以上的部署方式，而其中最知名也受歡迎的部署方式就是透過 Ceph-Ansible 來安裝。

本篇文章作者探討如何透過 Ceph-Ansible 來部署 Ceph 叢集。
Ceph-Ansible 內本身就有提供 Vagrant 的設定檔案，透過修改設定檔案就可以很順利的自動架起多個 VM，接者透過 Ansible 將 Ceph 的服務依序安裝上去最後就可以順利的搭起一個 Ceph 叢集環境來測試與開發。

本篇文章基本上要對 Ceph 有理解才會比較有背景去閱讀，對於 Ceph 有興趣的人可以參考看看

Crysis 3 Ending Part 8 Gods and Monsters

Crysis 3 is a first-person shooter video game developed by Crytek and published by Electronic Arts for Microsoft Windows, PlayStation 3, and Xbox 360. Officially announced 16 April 2012, it is the third main installment of the Crysis series, a sequel to the 2011 video game Crysis 2. The multiplayer portion of the game was developed by Crytek UK.

Set in the year 2047, the game takes place in New York City, which has been encased in a giant Nanodome created by the corrupt CELL corporation, and turned into a veritable urban rainforest. Crysis 3's story revolves around Alcatraz, Prophet's successor, and a Nanosuit holder who is on a quest to take revenge on the Alpha Ceph, the leader of the Ceph alien race, with the help of Prophet's former comrade, Psycho. The game's story serves as the end of the Crysis trilogy. Gameplay revolves around the use of the Nanosuit, which grants players a variety of abilities such as being invisible. New features introduced in Crysis 3 include a new Nanosuit ability called "Rip & Throw", a new compound bow and the "hacking" feature, which allows players to hack into enemies' equipment, drones, and automated security defenses.

The game is set in a post-apocalyptic New York City, in an effort to combine the urban landscape of Crysis 2 and the forest setting of the original Crysis. The game introduces the "Seven Wonders", with each wonder having its own unique landscape and tactical layout. Due to complaints about Crysis 2's linearity, the game's levels were opened up so as to grant players more freedom. The development team also put efforts into creating a more emotional story, and the story's protagonist, Alcatraz, was inspired by the lead character of District 9. The game was developed by a team of 100 people during its 23-month development cycle.

Crysis 3 was met with positive reception after its release. Praise was directed at the game's level design, visuals and multiplayer, while it was criticised for its story and length. With a budget of $66 million, the game sold 205,000 copies in its debut month, and became a commercial failure for Electronic Arts. The game was later included in The Crysis Trilogy, a bundle released on 20 February 2014.
