Stratos2.0的架构

Elastic Load Balancer (ELB)

• Load monitoring 装在监控
• Makes auto-scaling decisions. 自动扩展的决定
• Accepts dynamic cluster domain registrations. 接受动态集群域的注册
• Accepts static cluster domain registrations at start-up by reading the loadbalancer.conf 接受静态集群域的注册通过读取loadbalance.cnf

Stratos Controller (SC)

主要是图形化的UI；ADC负责把各个组件的控制嵌入到Stratos Controller；同时SC制定了自动扩展的策略。

Cloud Controller (CC) 云控制器

• CC充当一个桥梁在应用和IaaS的Jcould的API之间.

• It enables your system to scale across multiple IaaS providers.

• It is the central location where the service topology resides.

• It is responsible for periodically sharing up-to-date service topology among other Stratos 2.0 core services.

• It supports hot updates and deployment of its configuration files.

• It has inbuilt support for , 
  

  • AWS EC2 IaaS provider

  • Openstack Nova IaaS provider

  • VMWare vCloud provider.

• It enables you to cloud burst your system across multiple IaaS providers.

• It allows you to easily plug an implementation of any IaaS provider support by jclouds.

• It enables you to spawn new service instances, while associating a public IP automatically, to reduce the instance boot-up time.

• It enables you to terminate an already started instance of a particular service cluster.

• It can be configured to cover many scenarios, using it's well-thought-out configuration files.
