1.1 eucalyptus: open-source implementation of EC2Eucalyptus [22] is implemented by Daniel Nurmi of the University of California and is an open source software infrastructure for cloud computing. Eucalyptus is an open-source implementation of Amazon EC2. It is compatible with EC2 commercial service interfaces. Eucalyptus is a software framework for research commun
Recently, I have been familiar with the cloud computing platform eucalyptus and used it to build a cloud environment. Through some examples on the internet, I gradually found out how to build a cloud computing platform using eucalyptus. The Eucalyptus I use is a free version and lacks many features of the Enterprise Edition.
1. Preface
Elastic utility computing architecture for linking your programs to useful systems (Eucalyptus) is an open-source software infrastructure for elastic and practical cloud computing through computing clusters or workstation clusters. It was initially a research project at the University of California's Santa Barbara Institute of Computer Science and has now been commercialized and developed into eucalypt
Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems(Eucalyptus)是一种开源的软件基础结构,用来通过计算集群或工作站群实现弹性的、实用的云计算。它最初是美国加利福尼亚大学 Santa Barbara 计算机科学学院的一个研究项目,现在已经商业化,发展成为了 Eucalyptus Systems Inc。不过,Eucalyptus 仍然按开源项目那样维护和开发。
以下主要针对这段时间的学习情况,整理的桉树相关教程的汇总贴,方便大家查阅、交流学习,如果相关系列博文中有不对的地方,希望大家批评指正,我将第一时间核实后修改,避免误人子弟。基础知识篇

The database used in Eucalyptus is hsqldb.
The hsqldb-1.8.0.10 version is used in eucalyptus-2.0.2.

HSQLDB is an open source Java database with standard SQL syntax and Java interfaces that are free to use and distribute, very concise and fast. has three kinds of server mode, in-process mode (in-process) and memory mode (MEMORY-ONLY). Running HSQLDB requires a Hsqldb.jar pa

Network configuration for Eucalyptus
Eucalyptus's network features:
1. Connectivity: provides IP-level connectivity for virtual machines.
2. IP control: in System mode, the DHCP server assigns IP to the virtual machine, and other modes assign IP to the virtual machine by Eucalyptus.
3. security Groups : A set of network access rules provided for a set of virtual machines, similar to firewalls.
4. Elastic
