Cloudstack is an open-source, highly available and scalable cloud computing platform that supports the management of most mainstream virtual machine managers, such as KVM and XEN. There are two types of storage in Cloudstack: Primary storage provides disk volumes for virtual machine instances, and level two storage provides templates for virtual machine instances to install mirrored files for systems and disk snapshots of virtual machine instances. Both types of storage support network-attached storage (NAS). Figure 0. Cloudstack architecture This article we will be a Linux host ...

In this recipe, you prevent users from receiving a security certificate warning when your FortiGate performs full SSL inspection on incoming traffic.

Editor's note: With Docker, we can deploy Web applications more easily without having to worry about project dependencies, environment variables, and configuration issues, Docker can quickly and efficiently handle all of this. This is also the main purpose of this tutorial. Here's the author: first we'll learn to run a Python Dewar application using the Docker container, and then step through a cooler development process that covers the continuous integration and release of applications. The process completes the application code on the local functional branch. In the Gith ...

In our daily life, we are inseparable from the application of position recognition class. Apps like Foursquare and Facebook help us share our current location (or the sights we're visiting) with our family and friends.
