and software bring more problems and maintenance costs. So we use Packer and Vagrant to unify the production environment and development environment, Packer build operating system images for Vagrant to run the virtual development environment, so that all developers have a unified and continuously updated development environment, more conducive to reduce problems and collaboration. Packer-built mirrors are also available for large virtualization platforms such as KVM, Xen and ESXi, as well as

As one of the core services of cloud computing, storage services are used by every user. However, the current situation is: most customers in addition to virtual machine data disk (persistent disk), and does not fully utilize the storage services. Let's look at a typical scenario: for example, a Web application needs a user to upload an invoice scan (image file). At the code implementation level, the image files uploaded by the user are usually saved directly to the disk file system. In a tradit

I have previously written a post about Amazon Web Services (AWS), which should be the first large-scale attempt on the Web 2.0/SOA Infrastructure Leasing Market. Not long ago, in an interview with Microsoft's Internet service bus, a small-scale attempt provided to developers. I have basically enjoyed AWS and its potential markets. Since AWS launched S3, SQS, and

. When you try to extract content from the S3ql file system, if they are not in the local cache, the corresponding objects will be downloaded from the cloud and then decrypted and decompressed instantly. The need to be clear is that S3QL does have its limitations. For example, you can't mount the same S3fs file system on several different computers at the same time, and only one computer can access it. In addition, ACLs (access control lists) are not supported. In this tutorial, I will d
