Should data and processes be handled in a private or public cloud? If a company wants to use cloud computing, they first need to choose one of the many providers available. Using the personalized services offered by a private cloud, companies can address a wide range of business related and operational challenges. Separating operations also makes a private cloud more secure than a public cloud.
Cloud services are becoming increasingly important for companies. In addition to software and infrastructure that can be booked via the provider's cloud (SaaS and IaaS), cloud-based platforms for developing new applications (PaaS) are also becoming more popular. Companies can make their self-developed software available on these platforms without having to set up the necessary infrastructure...
Thanks to its minimalist dimensions, the Raspberry Pi Zero is the ideal component for all craft projects looking to utilize every last inch of space. Having arrived on the market in 2015, the minicomputer has been used in numerous constructions across a range of functions. A brief introduction to the minicomputer and of the most interesting Raspberry Pi Zero applications and ideas can be found in...
Cloud computing is not just an IT industry buzzword, it’s a model that many companies already employ effectively and profitably into their organisations. A large portion of IT infrastructure is no longer managed on-site. Instead, the required services can be rented via a service on the internet. Here we provide a cloud computing definition and explain exactly how it works.
The PostgreSQL database management system, also known to many as Postgres, has many decades of development behind it. It originally started as a project at Berkeley University in California. Today, the open source database continues to defy solutions from commercial competitors, since the development team is constantly working on its functionality and performance. But what exactly is PostgreSQL?...
A glance back into history can reveal a lot. Although token ring networks, or ring topologies, are nowhere to be found nowadays, token rings remain an interesting form of technology. Why the model, which is actually quite good, was outdone by its competitor Ethernet is due to the merciless nature of the tech market. Read the history behind token rings, along with a definition of the system that...
Autonomous cars, intelligent factories and self-regulating supply networks – a dream world for large-scale data-driven projects that will make our lives easier. However, what the cloud model is and how it works is not enough to make these dreams a reality. The challenge of effectively capturing, evaluating and storing mass data requires new data processing concepts. With edge computing, IT...
The communication protocol SNMP (Simple Network Management Protocol) is an elementary component of many network management applications. It defines a number of message types that greatly simplify the monitoring and administration of individual network participants such as PCs, routers, servers, switches, firewalls, or printers. How exactly the SNMP protocol works and what fundamental adjustments...
If a system in IP networks is to send data packets to different target hosts as efficiently as possible, an IP multicasting connection is the perfect solution. When it comes to multipoint transmission, the data packets are able to reach all interested parties thanks to various protocols such as GMP, for example. Switches and internet routers can also use the communication protocol for IGMP...
An exact system time on a computer is especially important when devices need to exchange data. Cross-system processes quickly come to a standstill if the generated time stamps are very different from the time that applies to the system. Synchronization methods that keep the clocks of the individual network participants in sync are utterly indispensable. One of the simplest methods to achieve time...
