When it comes to cloud computing, users and vendors are still exploring uncharted territory when they adopt the new infrastructure. Failure problems and unexpected downtime will inevitably occur. Even the biggest and best cloud makers are in vain before their services are occasionally "stopped". So what went wrong in the event of a cloud outage? What can IT managers and users learn from every event? To help readers better run their services, some downtime events are sorted according to the severity of the downtime incident. Microsoft is even testing ...

Experts: Five Views on cloud computing (1) cloud computing is the same as every it trend, including service-oriented architecture (SOA) and Web services. 　　We're talking about cloud computing, and maybe not the same basic concept. I recently joined a linkedin/google group on cloud computing, one of which has posted a sticker that looks so simple. The problem is: cloud computing and what we have ...

The Cloud Security Alliance (CSA) 's latest report, "The main threat to cloud computing", presents some emerging risks and modifies and reordered existing risks. The report, entitled "Nine sins: the main threat to cloud computing in the 2013", is based on feedback from cloud computing and the security community, where many individuals and organizations weigh the risks they face, which are the most recent reports that deserve more attention. As one of the three co-chairs of the Working group responsible for the report, I have raised a number of questions regarding the fourth threat on the list ...

With the popularization of Internet applications, more and more people start to use the services provided on the Internet. However, most of the Web sites currently providing services use user names and passwords to identify users, which makes it necessary for users to enter their username and password frequently. Obviously this kind of authentication has the disadvantage: with the increase of user network identity, users need to remember more than one group of user names, passwords, which give users the burden of memory; another frequent input user name, password, will correspondingly increase the user password password is cracked probability. In order to change this situation, single sign-on technology emerged ...

This article is my second time reading Hadoop 0.20.2 notes, encountered many problems in the reading process, and ultimately through a variety of ways to solve most of the. 　　Hadoop the whole system is well designed, the source code is worth learning distributed students read, will be all notes one by one post, hope to facilitate reading Hadoop source code, less detours. 1 serialization core Technology The objectwritable in 0.20.2 version Hadoop supports the following types of data format serialization: Data type examples say ...

Many people always like to hype the concept, if the concept of unfortunate interpretation, it will not let us accept it. Cloud computing is almost a concept, although in a sense it is like a once popular concept in the industry, but does not prevent it from becoming the hottest IT IT vocabulary. From IBM, Google, Amazon to Dell, and Microsoft (and, of course, a long list of company names later, if possible), these companies are sparing no effort in pushing the notion of cloud computing and from their own perspective Cloud computing ...

It seems the industry analysts, Google is positioning itself as the backbone of the cloud business instead of Amazon. Although there is still a big gap with it, but Google still have the opportunity to catch up and one day to seize its cloud overlord throne. "Amazon basically accounts for 80% to 85% of the current platform-as-a-service market share," said Jagdish Rebello, head of research at IHS iSuppli. "The market is currently in its infancy and the main driver of this market step by step , Amazon also naturally got ...

After dominating the dominance of the cloud computing world, Amazon Web Services made a lot of thinking, such as the future of the cloud world, what would it be like? While many believe Amazon Web Services will mimic businesses like Microsoft and IBM in the past, I personally do not think so. So what will the cloud world look like? I have some ideas, mainly based on the current mode of adoption. In four years, the focus will be on specific cloud services, not the cloud itself. As a result, there will be industry clouds that provide professional services, such as: ...

Because cloud computing can generally be divided into IaaS, PaaS and SaaS three different types of services, and different manufacturers have provided different solutions, so far there is no unified technology architecture, the reader understand the principle of cloud computing Constitute a hurdle. To this end, this article integrated programs from different manufacturers to construct a questionable cloud computing architecture. Cloud computing technology architecture is divided into 4 layers: physical resource layer, resource pool layer, management middleware layer and SOA building layer. The physical resource layer includes computers, storage, network facilities, databases, software, etc ...

Re-indexing the Internet Facebook hired Google to print public relations process has been completed. The question is: Google so many products, Facebook Why Social Circle so sensitive? Google: indexing the Internet Google claims its mission is to "index the Internet." The difficulty of this thing is not sent much crawler, but to sort the bulk of the collected content: how to make really important page, to Google ...

The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...

As cloud computing moves from test to production, the real world is increasingly focused on the details of cloud computing. We found the trend of cloud computing in the new Year. These hot topics may not be the hottest, but 2012 years of technology, the point of interest is heating up, some cloud computing problems and the main idea we will be in 2013 years to face. Large data analysis has confirmed this year the energy of large data and the competitive advantage it can bring to enterprises. According to Gartner, the impact of big data in the 2013 was only expanded through research on the web. ...

PaaS (Platform-as-a-service) is a kind of cloud service, the service provider not only provides on-demand hardware and operating system services, but also provides the application platform and solution stack. For developers, PAAs greatly reduces the cost and pain of it deployments, providing resources for applications to scale more easily as needed. JVMs, application servers, and deployment packages (for example, war and ear) provide natural isolation for Java applications, allowing different developers to deploy applications in the same infrastructure, so JAV ...

What is the benefit of the cloud, the advantages of the cluster will be everyone can think of, super storage capacity, large-scale integrated computing power and system load capacity, and cloud can be imagined as a larger cluster, theoretically its storage and computing capacity is almost unlimited, So the greatest benefit is that it greatly reduces the cost of data storage, including the cost of money. The cloud's first estimate is that Google's goal is to use it to distribute computer clusters around the world to reduce the cost of data storage, thereby bringing deeper cloud computing ideas.
