Not long ago, I wrote some articles about how my company went into the cloud storage. Specifically, we are mainly taking SaaS (software as a service) path. This is my solution to the problem of "Shoemaker's children have no shoes to wear". Although we are leading many people to quickly enter the cloud storage and large data era, we still ignore the use of their own equipment. This has led to many problems with cloud storage. 1. Backup unless you have two remote data centers or Dr Centers, and make sure nothing happens at the same time in two centers. Only the traditional "it ...

I have not written a blog for almost a year, it must be an excuse to say that there is no time, but the only reason is that when I get older, I find myself superficial. And some of their ideas have not been waiting to write, found that the original is very naïve, so dare not send to laughable. However, this time I would like to tell you a little story: once there were three cock silk, they gather together to do the network, they provide free network services, and even zaguomaitie, all night, in addition to selling kidney they have done. And in 3 years, they finally did 5 million users, I think for young people, can put 5 million ...

Remember when many friends chose to disable JavaScript on their browsers for security reasons. To this day, this has become ridiculous--for the simple reason that JavaScript has ruled the entire web world. In this new computing era, full of platform diversity, we need applications that can run in any device browser. Native apps may run faster and invoke a specific platform feature that more JavaScript cannot touch, but there's no denying that the cloud is coming and we're in it ...

Now Apache Hadoop has become the driving force behind the development of the big data industry. Techniques such as hive and pig are often mentioned, but they all have functions and why they need strange names (such as Oozie,zookeeper, Flume). Hadoop has brought in cheap processing of large data (large data volumes are usually 10-100GB or more, with a variety of data types, including structured, unstructured, etc.) capabilities. But what's the difference? Today's enterprise data warehouses and relational databases are good at dealing with ...

There are four letters. It seems that everyone is p-a-a-s this week. From the rumor that Microsoft has given up Azure's hybrid platform named Red Hat, a service plan, the development platform is beginning to bear the buzz from the cloud. 　　So what is the noise around the platform, the service (PaaS)? 　　PAAs provides many advantages over infrastructure as a service (IaaS), especially for companies that do not have the ability to deal with cloud infrastructure within the enterprise.

The following is the 2014 Big data field of the 10 emerging big data start-up companies 1. Aerospike founder and Cto:brian Bulkowski include MongoDB, COUCHBD and R ...

With large data growing in data centers and cloud environments, how to manage networks that transmit millions of of records at the same time is an unprecedented problem. This is not just a matter of data size--when it comes to large data network solutions, not only is the size of the data really negligible, but so does the workload. Large data environments do not simply operate on the basis of past data infrastructures. Given the complexity and speed of running large data application software, large data needs to be tailored to its own solution. The "traditional" data analysis architecture assumes a limited source of data, and they have ...

Introduction: Open source data processing platform with its low-cost, high scalability and flexibility of the advantages has won the majority of network Giants recognized. Now Hadoop will go into more business. IBM will launch a DB2 flagship database management system with built-in NoSQL technology next year.

Two companies are planning to provide assistance with deployment services and enterprise-level support. Oracle has pledged to preinstall Hadoop software in large data devices. Large Data Leather ...

From an enterprise IT architecture, especially for Web2.0 sites, scalability must be considered: the ability to expand IT systems in a timely manner as the number of users increases. There are usually two ways to solve this problem: Scale up and Scale out, and two modes of expansion address database pressures from two dimensions. Scale out (scale-out): literally, Scale out uses increased computing power by adding processors and adding independent servers. Refers to the enterprise ...

The study is based on the thought that humans tend to think and make decisions based on their experiences and the examples they see. For example, a child may know from several words spoken by his parents that they are talking about summer camp because they have been there last year and they know that words such as "month," "Lake" and "counselors" will only be used together in this situation. However, if we have limited experience or perhaps no experience in a particular field, a little help may be necessary--that is Bayesian Cas ...
