In this experiment, I am trying to build an IaaS inside container.Better to name -"container cloud".
If you don't know about different types of clouds, please visit my post :
Different types of Clouds:
SAAS: SOFTWARE AS A SERVICE
PAAS: PLATFORM AS A SERVICE
IAAS: INFRASTRUCTURE AS A SERVICE
Common Examples of SaaS, PaaS, & IaaS:
SaaS:Google Apps, Dropbox, Salesforce, Cisco WebEx, Concur, GoToMeeting
PaaS:AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, OpenShift
IaaS:DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE)
There are different types of containers and their pros & cons. you can get some details here :
I am choosing LXC!!! why?
- nearest like VM , its VE.
- Allows iptables -easy like VM. For IaaS , I am choosing Opennebula. My these two articles can help you to understand more about opennebula:
STEP-1: Download and run lxd. New to containers? or LXD? learn here:
STEP-2: Download and run Opennebula.(https://github.com/OpenNebula/minione)
c1 is my container.
If you have kvm enabled host then try kvm / firegate else lxc minions script.
