Swift Programming Language
Swift Programming Language is developed by Apple. Another Swift Language exists, which is an implicitly parallel programming language. The later Swift parallel scripting language is an easy way for parallel scripting on multicores, clusters, cloud and supercomputers. The later Swift, is implicitly parallel, means that the program statements will automatically run in parallel unless there is a data … [Read more...]
Internet of Things, Cloud and Espionage of Safety
Internet of Things (IoT) is a concern not only for the security, all cloud based service providers and to the software defined approaches. Since 2010, we are mostly around the topics of core Networking and Virtualization. Gradually, we introduced Cloud Computing as a category. So, far we have the highest number of helpful information providing articles, guides on Cloud Computing as a single … [Read more...]
Intel’s Monitoring Software for OpenStack : Expanding SDI
Experimentation gone well with OpenStack Cloud from public cloud to virtual private, now something towards Software Defined Infrastructure. Intel continues the path of Software Defined and automation, presenting a software for monitoring the performance of the nodes OpenStack Cloud. Software Defined Infrastructure can only be realized faster if we think from the current state OpenStack. Intel has … [Read more...]

OpenFlow : The Enabler of Software Defined Networking
OpenFlow switching is a technology that grew out of the research project named OpenFlow: Enabling Innovation in Campus Networks in 2008 at Stanford University. OpenFlow is an enabler of Software defined networking (SDN). OpenFlow is defined as an emergent and open communication protocol that allows a server software to determine the packet forwarding path that should be followed in a network of … [Read more...]
Relationship of Cloud Automation and Abstraction
In the era of Software Defined, Cloud automation may not be a direct consequence of abstraction due to some operating limits of the systems. We Are Reaching an Age Where Computing is Defined by Software. Software Defined Storage Virtualization, Software Defined Network and the convergence - Software Defined Data Center (SDDC). Abstraction is a frequently used terminology especially in articles of … [Read more...]
