There are too many clouds in the industry, each of which is very distinctive! For Microsoft, Windows Azure is the core of its cloud strategy. I have always had a vague impression on it, David Chappell's article-introducingWindows azure-a detailed introduction to the basic knowledge and features of Windows azure helps clarify some previous misunderstandings. For example, Windows azure has always been regarded as a PAAs platform, but with the introducti

A recent prospective customer asked us to compare Amazon EC2 and Google App Engine. We just finished two relatively large projects on EC2 and Google App Engine, therefore, it is necessary to make a summary. I plan to compare the two cloud computing platforms from three perspectives: technology, business, and future development trends.This article is a technical comparison. OK. Prepare coffee. Let's get started! If you score by platform type, you may already know that Google App Engine belongs t

First, popularize knowledge. Cloud computing can be divided into three types from the perspective of service methods: Public clouds that provide open computing and storage services to the public ", such as Baidu search and various email services; deployed in the firewall to provide a "private cloud" for a specific organization "; and the "hybrid cloud" that combines the above two service methods ". From a technical perspective, cloud computing can be divided into four layers: Haas (hardware as a

Background UAE (UCAppEngine) is a UC internal PaaS platform with a general architecture similar to CloudFoundry, including: Rapid Deployment: Support for Node. js and Play! Framework information such as PHP is transparent: O M process, system status, service status gray trial and error: IP gray level, regional gray level basic services: key-value storage, MySQL high availability, image platform, etc. Background: UAE (UC App Engine) is a UC internal

"Introduction to the Background"Traditional PAAs uses sandbox to implement the resource security isolation between the app, sandbox needs the operating environment and programming language for the underlying functional limitations, such as: Prohibit the creation of processes and threads, prohibit some system calls, prohibit the reading and writing of some system paths, prohibit the loading of C language modules, Prohibit certain network function, this

resources and information can be provided to computers on a variety of terminals and other devices on demand. Cloud computing describes a new internet-based IT service growth, usage, and delivery model, often involving the use of the Internet to provide dynamically scalable and often virtualized resources. The service is divided into the following modes:Infrastructure as a service (IaaS): Consumers use processing, storage, networking, and various basic computing resources to deploy and execute

two combinations, but there are some differences:Package Capacity:The image of Docker can be easily implemented on the CentOS run Ubuntu, and very light, this is rpm,deb do not have;This is very valuable in some testing, learning, or small-scale PAAs scenarios;But for any larger-scale application, I think it is unlikely that such a deployment will occur;Package granularity and Dependency management:Docker from the kernel, fully packaged in a piece, w

Nostalgic, remember this interface?Yes, this is the first edition of Windows Azure Management Portal, developed with Silverlight, awesome!Strange, why not virtual machine?Yes, there are no virtual machines in the original Windows Azure!You see the hosted service? This is the predecessor of cloud service. Windows Azure was originally started from the PAAs, it is not difficult to understand-Microsoft's operating system, development tools are industry-le

Pivotal Web Service Supervisor Engineer Product Manager Wu JianWhen it comes to cloud computing services, it's common to think that in a machine-roaring data center, each rack is arranged together, a server is working nervously, and it seems that building a cloud computing environment requires many powerful servers. But in fact, both OpenStack, which provides IAAS services, or cloudfoundry that provide PAAs services, can be installed on a single compu

This is a creation in Article, where the information may have evolved or changed. "Editor's words," O sheng in the small and medium-sized enterprises to do services, the actual encounter many situations, such as the other side it is too weak, such as the infrastructure is too shabby, such as products to solve the industry needs, corporate personality needs, and so on, after several years of accumulation at present to explore a complete set of product solutions. At present, the product is a conta

new trends in radar Register, CTO, ThoughtWorks China 1. Open SourceOpen source has been transformed from a simple organization of software code into a culture, a movement. When it comes to open source, it is no longer a cheap substitute for a simple commercial product, but instead becomes a manifestation of soft power for a software company. Unlike in the past, more and more companies are now opening up their important software assets to attract candidates and realize their value.Innovative o

of system technology and business reform faced by enterprises, we should build the PAAs Office capability platform beyond the traditional PAAs category, strengthen the business capability and technical capability components, and form a more targeted "thick PAAs" platform. Through this platform, we can unify the technical framework, unify process management, impr

feature to provide sqlfire enterprise 1.0. This version removes the number of knots that can be interconnected, adds support for nodes that can span the Wan, and provides a way to hold globally distributed data. Finally, some customers want to use open-source runtime components, such as Apache Tomcat and Apache HTTP Server, and do not want to be forced to use vfabric for anything. VMWare also supports vfabric. Mcjannet said: There is no doubt that developers are choosing popular techn

provided by the OSC, and I was dumbfounded: grails applications require a lot of memory. At this point, I faced two choices: spend money on upgrading PAAs memory, or give up. A few days a tangled, decided to give up, and then rewrite. Through this, I have a good liking for grails, so I did not delete the CRM8000 on the OSC project, but to re-project, this is the PSI. PSI Project I learned my lesson, starting with the first line of code, I tested

quickly scale their IT operations to respond to sudden change demands while maintaining high-speed performance. Second, they can move non-sensitive features to the public domain to reduce their need for their on-premises private clouds.3. Cost-effectivenessOne big advantage of hybrid cloud is that it lowers costs. Because the hybrid cloud is configured to use both public and private clouds, it allows users to access large-scale economic benefits, such as centralized management, without exposing

Teach you how to deploy the Node. js application on heroku cloud platform, herokunode. js Although AWS has also launched its own PaaS platform called Elastic Beanstalk, heroku has many third-party add-on, such as MongoDB, mysql, redis, and memcached, there are also various plug-ins such as message queue, sms and email, backend batch processing, search, and automatic monitoring. They are much better than AWS in the ecological environment. That is to sa

increasingly moving away from. NET. NET open source does not guarantee that Microsoft will get a large influx of developers. Developers can still choose Java, PHP, node. js, Ruby on Rails and other languages.In a way, the company is playing with fire and the company will. NET open source execution on other platforms may make developers think this is only due to the lack of Microsoft technology.5, let the platform as the front-end service. when the Enterprise chooses

ultimately form the technology of the software system to be developed. It can be seen that the use of metadata-driven technology makes the software development process transform from the traditional code development process to the metadata definition process. Metadata (metadata) is the data aboutdata ), each part of the software system includes the user interface, business logic, data access, workflow control, business permissions, and report presentation. We all consider this part as data and

As the mobile development platform started the positive move, why in the competitive time, the release of enterprise mobile portal-positive work? Positive work into the enterprise level of the B

command is somewhat complicated, if interested, here is an article I previously wrote based on Lxc, (from scratch, to build a simple version of the Java PAAs Cloud platform), you can review it in advance. The principle of implementation, the relevant theory, the use of scenes, etc., will be written in the back of this series, here first a taste, completely manual, based on Docker to build a tomcat operating environment. First out of a good demo, you
