Cloud Computing Week Jevin review: Sweep 18 major databases

Sweep 18 kinds of mainstream database: 12 kinds of sql+6 species NoSQL

Remember that two or three years ago there were only a handful of cloud computing platform vendors to choose from, it seems that there is not much cloud database in the market. But after the cloud boomed, the cloud database also appeared to be springing up. And what is really reliable and easy to use, for users, and bad analysis. So, this paper analyzes the usability and application direction of 18 kinds of databases (note that the Management database service is not the database instance that still requires user management and implementation). There are still deficiencies, and I would like to hear more comments.

Google 120 dollars fiber, let me 100 yuan 8M broadband Love why!

Now, the Internet has become an indispensable part of our lives, the development of the Internet can not be separated from the support of high-speed speed.

At present, Verizon's FiOS can reach a speed of 300Mbps, but it is expensive. At&t's verse price is relatively cheap, but its speed limit is poor compared with FiOS (up to 24Mbps).

Google wrote in its Thursday blog post: "Google Fiber will be faster than the current broadband average speed 100 times times." No more buffers, no more load, no more waiting. Gigabit speed will let people out of these annoying, outdated problems, to the site opened up new opportunities. ”

As Marcus Wohlsen said in an article on Wired, it would be far more meaningful than the Internet services it provides for cloud services.

The most promising 12 programming languages in the cloud computing age

Do we need a new programming language? You may not think you need it, but if you go to the latest trends, you may change your mind. Why does Google use go and dart two programming languages? Why do IBM, Cray, and Red hat create the three languages of X10, Chapel, and Ceylon, respectively?

In the future, are these 10 programming languages (DART, Ceylon, go, F #, OPA, Fantom, Zimbu, X10, Haxe, Chapel) able to shake it. Are the new programming languages designed to meet the creative impulses of some people or the technological evolution of new programming methods?

Review history

If you look back, we can see that the eruption of the new language divides history into 3 periods, each of which is linked to the tipping point of technological evolution.

Other important languages are in addition to the time points in the figure: (1) pascal–1970, (2) c–1972, (3) prolog–1972, (4) smalltalk–1972, (5) erlang–1986, (6) perl–1987, (7) C #

Does cloud computing use these languages? If you analyze the stories behind these new languages, you will see an emerging common theme.

Uhuru launches Cross-platform applications

Uhuru's new Appcloud Ready to go is ready to develop an application across the. NET and open source world for developers. Michael Surkan, director of product marketing at the company, says the platform runs on the Open-source platform of Cloud foundry and supports Java, Ruby, PHP, Node.js, and Microsoft. NET Frameworks.

Last December, Uhuru launched a. NET beta version of its PAAs and added support for other languages, as well as a new management console and integrated into popular applications, including WordPress, SugarCRM and Magento. Surkan said Appcloud Ready to went on the inside of late June and signed an agreement with 1100 developers.

Oracle buys Xsigo VMware, Cisco competition intensifies

Oracle announced the acquisition of Xsigo in Monday, but did not disclose the amount of the acquisition. Last week, VMware grabbed Nicira's revenue before Cisco, and Sdn's battle came to a climax.

Xsigo offers what is called DCF, and the DCF is designed for virtualized networks to minimize the physical network card and network cable. In a traditional data center, a physical machine running more than one virtual machine, and each virtual machine needs to use a physical network card, many times a physical machine requires 6 to 8 physical network cards. And Xsigo such a virtual I/O system, by creating multiple virtual network adapters, so that administrators can easily invoke. Xsigo is similar to HP's virtual connectivity products, but the latter only supports HP products, while Xsigo supports many vendors ' products.

Either Nicira or Xsigo, which has just been bought by VMware, has hit Cisco, the network giant. Nicira can replace Cisco's expensive switches and routers with ordinary hardware. Its network controller can run on any network device, which of course includes relatively inexpensive network equipment procured from mainland China and Taiwan. Xsigo can also reduce the number of switches used.

The impact of Oracle's takeover of Xsigo News was that Monday VMware and Citrix shares plunged 3.48% and 5.86%,oracle shares fell slightly 0.62. Cisco rose slightly by 1.15%, though Cisco's shares fell 4.1% last week. Gabriel Lowy, an analyst at Mizuho Securities, said investors were too worried about the changes in the SDN market.

The acquisition will further increase the competition between Oracle and VMware in virtualized management systems.

Dropbox launches new security mechanism to beware of hackers invading again

In the evening of Monday, Dropbox admitted that the spam that plagued the users a few weeks ago was due to hackers from third-party websites who obtained the accounts and passwords of "minority" Dropbox users.

Our survey found that recently stolen user names and passwords from other sites were used to log into a handful of Dropbox accounts. We have contacted these users and helped them protect their accounts. An Dropbox employee has also been invaded, and his account contains a project file with a user's e-mail address. We apologize for this and will take more control measures to ensure that such incidents do not recur.

Comparison of investment system architecture of six major cloud service providers with input evaluation output

How much did the most popular cloud-computing providers such as Apple, Facebook, Zynga, Google, Microsoft and Yahoo spend on cloud infrastructure as the cloud market began to yield revenue?

To calculate benefits, it is clear that the calculation of revenues and profits is accompanied by an understanding of the actual cost of spending in the construction and operation of Internet applications, or that it is one of the key indicators of how well the cloud operators or suppliers are going to be in the clouds.

Here's an analysis of the cloud infrastructure spending by the author, Derrick Harris, with the most popular companies like Apple, Facebook, Zynga, Google and Microsoft as templates, But first you need to be aware of a problem: not all expenditures are on the network infrastructure (data centers and servers)--The general category is "acquisition of property rights and equipment"--but most of them do.

Among them, Apple is apparently to make up for the lack of previous investment, in Q3 (note: Apple's financial planning time is obviously different from the natural month), the expenditure than 2011 growth of 164%, more than 2010 year, the equivalent of 2009 year twice times. Facebook's capital expenditure is by far the highest in total revenue. It is 212% higher than last year, more than Apple. Facebook has even spent 52 million of dollars renting related equipment. Zynga (social gaming company) has an impressive 42% reduction in investment, compared to last year. This is partly due to the fact that it has already completed the construction of a private cloud infrastructure. In addition, the dollar marked the recent spending plans of Google and Microsoft.

Rackspace hp startup OpenStack business really mature?

August 1, Rackspace and HP respectively completed the OpenStack cloud products based on the main part of the beta, and began to achieve universal delivery of users, this is called the OpenStack development process of a milestone, for users, OpenStack is no longer a castle in the sky , Touch not. We are pleased to see that there are already products present in front of the user, which means that OpenStack has opened large-scale commercial applications, and more crucially, OpenStack can be constantly iterative, reconfigurable and mature in mass business, which is critical to win more large-scale and critical business applications in the future. But admittedly, OpenStack still has a long way to go, the HP cloud and Rackspace host services are only just beginning, still need a lot of load and time test.
