This article shows how to setup an active-passive session-aware load balancing cluster (SLBC) consisting of two FortiGate-5000 chassis, four FortiController-5103Bs two in each chassis, and six FortiGate-5001Bs acting as workers, three in each chassis.

I believe you have seen in many places "Docker based on Mamespace, Cgroups, chroot and other technologies to build containers," but have you ever wondered why the construction of containers requires these technologies? 　　Why not a simple system call? The reason is that the Linux kernel does not have the concept of "Linux container", the container is a user state concept. Docker software engineer Michael Crosby will write some blog posts and dive into Docke ...

In this recipe you set up a FortiGate Clustering Protocol (FGCP) virtual clustering configuration with four FortiGates to provide redundancy and failover protection for two networks.

One of the features of cloud computing is the ability to move applications from one processor environment to another. This feature requires a target operating system to receive it before moving the application. Wouldn't it be nice if you could automate the installation of a new operating system? A well-known feature of the intel™ architecture system is the ability to install Linux automatically. However, installing Linux automatically is a tricky issue for System P or IBM power BAE using the hardware management console. This article discusses the solution of ...
