ZStack - Networking Model 1: L2 and L3 Network
http://zstack.org/blog/network-l2.html
Networking Model 1: L2 and L3 Network. By Frank Zhang on Apr 4, 2015. ZStack abstracts the networking model into L2 and L3 networks. An L2 network provides a type of L2 isolation method, while an L3 network basically represents a subnet associated with OSI layer 4 layer 7 network services. The idea is to use terms and concepts with which administrators have been familiar to describe ZStack's networking model, allowing administrators to create networking topologies easily and precisely. In order to achiev...

ZStack - The In-Process Microservices Architecture
http://zstack.org/blog/microservices.html
The In-Process Microservices Architecture. By Frank Zhang on Apr 4, 2015. To tackle challenges such as significant operations overhead, duplication of effort, testability that microservices usually faces, and to achieve the benefits such as code decoupling, easy to scale-out that microservices brings in, ZStack encompasses all services in a single process called management node, building a in-process microservices architecture. Microservices are much more beyond we have talked. Services especially those ...

ZStack - ZStack's Scalability Secrets Part 3: Lock-free Architecture
http://zstack.org/blog/lock-free.html
ZStack's Scalability Secrets Part 3: Lock-free Architecture. By Frank Zhang on Apr 4, 2015. Textbooks tell us that lock and semaphore are answers to synchronization and parallelization; the straight idea to deal with them in a distributed system is to use some distributed coordination software like Apache ZooKeeper. Or something similar built on Redis. A system overview of using distributed coordination software, for example, ZooKeeper, is like:. Synchronous vs. Synchronized. Synchronous and synchronized...

ZStack - ZStack's Scalability Secrets Part 1: Asynchronous Architecture
http://zstack.org/blog/asynchronous-architecture.html
ZStack's Scalability Secrets Part 1: Asynchronous Architecture. By Frank Zhang on Apr 4, 2015. ZStack offers an architecture that 99% tasks are executed asynchronously, which is a key design that a single management node can manage hundreds of thousands of physical servers, millions of virtual machines, and handle tens of thousands of concurrent tasks. No, that is wrong! Isn't that good enough for communications inside IaaS software? The cause of IaaS scalability issue is: slow tasks. Traditional IaaS so...

ZStack - ZStack Download
http://zstack.org/installation
For people wanting to try out ZStack quickly, the best way is to install all software including KVM on a single machine so you can build your first cloud with only one machine. Because of this, we recommend below hardware specification:. 4 Cores Intel/AMD CPUs supporting VT-x or SVM. Fast link for users of Mainland China (国内用户请点击展开). 如果用户是内网环境,有内部yum源,或是有特殊的yum源,请先设置好内部yum源 包括epel的源 ,然后在安装的时候不使用参数'-R aliyun'。 如果可以解析,但看到的IP不是127.x.x.x或者不是本机IP,则可能是DNS劫持,可以执行以下命令将hostname映射至本机. The installation script will ...

ZStack - The Versatile Plugin System
http://zstack.org/blog/plugin.html
The Versatile Plugin System. By Frank Zhang on Apr 4, 2015. EBay's Chief Engineer in charge of the OpenStack private cloud, Subbu Allamaraju says:. Plugins originated from strategy pattern. Plugins originated from observer pattern. Most software claimed as pluggable either implement one of those forms or have part of code implementing those forms. To be fully pluggable, the software must be conceived with the idea that all business logic should be implemented using those two forms, which means the en...

ZStack - The Tag System
http://zstack.org/blog/tag.html
By Frank Zhang on Apr 4, 2015. Hardware, or selecting a host already having VMs of the same user running. The IaaS software can hardly provide individual API for all of the endless, unpredictable requirements, there must be a mechanism allowing base APIs(e.g. APICreateVmInstanceMsg) to carry extra information. In ZStack, tags are essentially strings carrying small pieces of information that associate with resources. A tag is mainly made up of below fields:. Resource UUID that the tag is associated with.
