Soa Learning

Cloud computing has become the hottest topic in the IT field, and its popularity has far surpassed the once-fiery concept SOA. And not long ago, Burton's analyst Anne Thomas Manes published a post called "SOA is Dead" has aroused extensive discussion in the industry. Anne said in the article, as an outdated concept, "SOA" is no longer necessary, but the idea of "services" in the cloud computing, SaaS and other technical fields continue. However, from the perspective of cloud computing ...

What SOA can learn from cloud computing: Service Design Some companies that deploy services in cloud computing, such as Amazon, Thewebservice, and force.com, do very well in service design. Many SOA projects create services that are not overly coarse-grained access control, or fine-grained access control, and are not well designed. The reality is that these services are not well defined and designed and are not sold well when they are offered on demand. Therefore, those who provide services outside of cloud computing must spend a lot of time on the main ...

Looking back on our recent history of technology development, it is clear that since distributed computing and its related technologies (such as grid computing and SOA) have been widely adopted, the cloud computing movement has emerged. Although cloud computing has become a new technology, there are many questions about this new technology. The 1th installment of this series will outline cloud computing, then analyze the various layers of the cloud, introduce different cloud types and their pros and cons, and explain why cloud computing campaigns are for enterprise development ...

It consumerism-or a mix of personal and business-technology equipment and applications-is a defining phenomenon in time. Recent predictions suggest that the number of mobile devices will exceed the world population in 5 years. In the past 10 of years, the proliferation of smartphones and social media applications has changed the development of applications. As a result, open source application interfaces (APIs), Software as services (SaaS), and cloud computing have emerged. Today, application developers and enterprise IT planners are focused on more changes in their work. These aspects have a lot of compiled articles, to explore the IT elimination ...

The open source software movement is a massive campaign involving program engineers and other computer users. It is a branch of the free Software movement, but the difference is not obvious. In general, the free software movement is based on political and philosophical ideas (sometimes referred to as the so-called hacker culture) idealistic movement, while the open source movement is mainly focused on the quality of the process itself. 　　 　　The key to open source's use of cloud computing to make a turnaround is to capture the expertise of cloud computing in distributed computing. 　　 Can the open source movement be revitalized by cloud computing? ...

In all respects, 2012 is a good year for cloud computing. In addition to becoming a favorite in the media's eyes, cloud computing has also harvested a lot of corporate hugs. Despite good results, in terms of market revenue, the cloud computing market is not optimistic, cloud computing provider's performance is very low, because from the relevant data to see orders into less than 1%, but from another point of view, the future of cloud computing potential is quite large. Cloud computing providers and potential suppliers are thinking: How to transform a service into a successful commodity harvest. Fortunately in the cloud ...

Today we're going to introduce Vsphare, starting with the entire third generation suite, with a virtualization consolidation ratio of around 30%. By 2010 to reach 40%, and now the fifth generation of precipitation can achieve more than 50% of the integration efficiency. For now, all the virtualization consolidation is accelerating, because customers have realized the benefits of virtualization, the benefits of cloud computing, so the entire virtualization is expanding, the fifth generation of Vsphare has been very optimized. This map is the fifth version of the cloud computing platform's main function, the most important is vSphare5, ...

As architects and designers, we often focus on what we have at hand and seldom reflect on the past. We should know the new from the warm. I've summed up 6 experiences from my 55-month experience as the Skype architecture group. Some are technical and others are softer views of the architect. First, introduce Skype background information. Skype background Skype is software that allows users to make audio and video calls, and can also make regular calls and send short messages. The company was founded in 2003, since its inception there is an incredible growth song ...

Now many industries or services are under the banner of cloud computing, but not all of it is cloud computing, quweicunzhen see cloud computing, is to grasp the real core cloud computing, cloud computing has two important aspects, integral, neglected, one is centralized computing, one is distributed computing, Cloud computing is a historical product that blends both in a specific way. Ignoring any point will have serious one-sidedness. Now a lot of "pseudo cloud computing" is not necessarily said to be completely detached things, but to the cloud of a side, or some of the history of a local source, exaggerated to the cloud meter ...

August 3, 2013, "Sky City" in Japan hit a new 143,119 tweets per second Twitter peak record, Twitter is the average number of tweets per second (TPS) 5,700 of 25 times times. 　　It is noteworthy that, in the absence of an indication of the "flood peak", the new Twitter system platform has not been flooded with the push-text jam caused by any delay or even downtime. The performance of the old Twitter architecture compared to the new architecture just three years ago, in the 2010 World Cup, a penalty and a red ...
