An authorized security evaluation test for SAE I. background and description Due to slow access to foreign servers and frequent access failures, we have been working with SAE to migrate the WooYun project to a stable SAE platform for a long time, later, we established cooperation with Sina SAE on security, including the security evaluation test. On the other hand, most discu

60 Open Source Cloud Applications "Part 1" (The Open source app you Can use in the cloud)This article is translated from http://www.datamation.com/open-source/60-open-source-apps-you-can-use-in-the-cloud-1.html, the original author Cynthia Harvey, translator HCBBT, please specify the reprint.I do not know too much about the cloud service, I hope to use this article up the posture, the way to practice English, if there are translation errors hope to point out, welcome to Exchange ~ Today, m

SPI service model for cloud computing Although there is no uniform definition of cloud computing, we have a relatively unified understanding of cloud computing service models. We know that cloud computing improves resource utilization by sharing resource pools. In cloud computing, the cloud computing service model can be divided into three types based on the resource categories in the resource pool, namely, the so-called SPI model, as shown in Table 1.1. Table 1.1 SPI Model Resource category clo

This is a creation in Article, where the information may have evolved or changed. "The editor's words" B station has been concerned about the development of Docker, last year successfully implemented Docker on the core SLB (tengine) cluster. This year we chose Mesos after comparing the various Docker implementations. Combined with CIAMP;CD, the Docker on-line process of the entire business was opened, and fully automatic expansion capacity was realized. This time combined with our implementation

1.Docker IntroductionDocker is an open source tool that you can use to wrap any app in the LXC container. If you say VMWARE,KVM packaged virtual machines, the Docker wrapper is the app. is a worthy PAAs.When the app is packaged into Docker image, deployment and operations become extremely simple. Can be used in a unified way to download, launch, expand, Delete, migrate.The dock can be used to: Automate packaging and deploying any application Create a lightweight private

Addresses in the data center. The underlying server uses AAs (Application Addresses) and the upper-layer switch uses LAs (Locator Addresses ). In this address allocation method, the server considers that it is in the same subnet as other servers because they use the same AAs address prefix. VL2 implements addressing by adding the shim sub-layer, ToR switch tunnel, and Directory System in the server protoco

: • Cloud software as a service (SAAS): The capability provided to users is to use applications run by service providers on the cloud infrastructure. You can use various client devices to access applications (such as browser-based Emails) through a thin customer interface (such as a browser ). Users do not manage or control underlying cloud infrastructure, such as networks, servers, operating systems, storage, or even individual application capabilities, unless they are special application con

customers. Platform as a service (PAAs) is used to provide a development platform as a service to users. Infrastructure as a service, infrastructure as a service (IAAS), serves to provide virtual machines or other resources as services to users. I) SaaS Model In SaaS mode, users only need to connect to the network and use a browser to directly use applications running on the cloud without worrying about installation or other things, in additio

measure in the world. It is often just a simple comparison with the existing curing process. In the PaaS field, people are used to connecting DevOps. In addition, the existence of PaaS greatly simplifies the management of applications by traditional O M personnel after release, therefore, platforms like Kubernetes are indeed sought after by traditional O M personnel, and the release of O M seems to have

and Organizations of the cloud computing service. All infrastructure content, computing resources, network bandwidth, and service security are managed and maintained within the Organization. It ensures the privacy and security of resources. The disadvantage is that the cost is high and the technical requirements are very high.Microsoft's Windows Server 2012 R2 and System Center 2012 R2 series provide users with complete private cloud solutions.3.
