If you want to create a private cloud, you need to use management software to create a virtual pool of computing resources, provide access to end users, and deal with security, resource allocation, tracking and billing issues. We tested five mainstream private cloud management products: Novell's Cloud Manager,eucalyptus Enterprise Edition, Opennebula,citrix Lab Manager and cloud.com cloudstack ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

According to Bernard Golden, chief executive of Hyperstratus Consulting, a survey of one after another shows that security is the most worrying issue for potential users of public cloud computing. For example, a April 2010 survey noted that more than 45% of respondents felt the risk of cloud computing outweighed the benefits. A similar concern was found in a survey conducted by CAS and Ponemon Cato. However, they also found that despite these concerns, cloud applications are still being deployed ...

Public cloud computing security--the most worrying problem for potential users One example of the public cloud computing security problem is that a April 2010 survey found that more than 45% of respondents thought cloud computing risks outweighed earnings. A survey conducted by CAS and Ponemon Cato also found that users have such concerns. However, they also found that, despite the user's doubts, cloud applications were being deployed. The continued release of similar surveys and results suggests that mistrust of cloud computing security continues. Admittedly, most of the security of cloud computing ...

The REST service can help developers to provide services to end users with a simple and unified interface. However, in the application scenario of data analysis, some mature data analysis tools (such as Tableau, Excel, etc.) require the user to provide an ODBC data source, in which case the REST service does not meet the user's need for data usage. This article provides a detailed overview of how to develop a custom ODBC driver based on the existing rest service from an implementation perspective. The article focuses on the introduction of ODBC ...

Overview 2.1.1 Why a Workflow Dispatching System A complete data analysis system is usually composed of a large number of task units: shell scripts, java programs, mapreduce programs, hive scripts, etc. There is a time-dependent contextual dependency between task units In order to organize such a complex execution plan well, a workflow scheduling system is needed to schedule execution; for example, we might have a requirement that a business system produce 20G raw data a day and we process it every day, Processing steps are as follows: ...

As I mentioned in the previous article, with SQL Services as a general development of small and medium sized applications, you can forget about the existence of SQL Server 200X. Is it that amazing? 　　Now it's time to learn more about the sanctity of SQL services. In most cases, Web applications need to rely on another database server. This database service requires professional IT people to maintain. Before you deploy your application, you need to think too much: Does the data server have enough capacity? Performance How ...

Once you have successfully compiled and installed the software, you will be ready to configure SLAPD (8) for your site. The SLAPD runtime configuration is done primarily through the slapd.conf (5) file, which is typically installed in the/USR/LOCAL/ETC/OPENLDAP directory. You can also use command-line options for additional configuration files for SLAPD (8) or SLURPD (8). This chapter describes the general format of the configuration file, followed by a detailed description of the common configuration file directives. Configuration file Format SLA ...
