Virtualizing is becoming more and more important: Its basic concept is that one imposes a virtual, abstract system onto an actual real system. Both software and hardware can be depicted in this way. In order to create a connection between the actual and the virtual system, one requires an additional layer – the hypervisor.
Remote direct memory access technology makes it possible to transfer data at maximum speed, very low latency and without burdening the CPU. The RDMA transfer process does not utilize a computer’s processor nor its operating system, which results in a data transfer that is considerably quicker. Find out how it works in this article.
Ceph is a storage solution that enables the shared filing of data in a network, which ensures the redundancy, scalability, and maximum performance of the existing infrastructure. The system was released with a GNU General Public License and can be used free of charge.
GlusterFS is a well-established and free distributed file system. It can provide storage space from several servers on the same network as a single drive, which gives it several advantages: Available devices are used efficiently, network load is distributed, and the risk of failure for individual components is lowered.
It no longer makes sense to store large volumes of data, like those that accrue in big data applications, in conventional file systems. This is where solutions such as GlusterFS and Ceph come into play, which have easily scalable data memory and provide metadata with repeated redundancy. Using only a central directory, such as a classic hard drive, is no longer enough for this purpose.
The NFC feature opens up a range of possibilities for smartphone users. Market-ready NFC applications can be used for mobile payments, for example. We explain what NFC is precisely, how the technology works and for which applications it can be used.
“Does it have Bluetooth?” This is a question you hear all the time in electronics stores, which is completely understandable, since this small, blue runic symbol has been a defining marker in our digital lives for quite some time, longer than most other wireless technologies. Even conventional kitchen appliances and motorcycle helmets all come with Bluetooth chips. You will find everything you...
Multicloud refers to the parallel use of multiple cloud services, such as public, private, or hybrid clouds. This allows you to use different cloud models at the same time and choose the best variant for each application. The individual cloud models can even come from different providers.
The Internet is dependent on various protocols for facilitating communication. The File Transfer Protocol ensures that we can upload data to a server and download it again at a later point. You’re bound to run into FTP again and again, especially in the context of creating websites.
Remote procedure calls have long played a critical role in inter-machine communication when it comes to client-server architectures. For several years now, gRPC has proven to be a worthy successor. This framework uses powerful strategies to fulfill the increased demands of global networking and end-to-end digitization.
