Edge computing is a distributed and open IT architecture with decentralized processing power, ready for mobile computing and Iot technologies. If you want to imagine edge computing, it is easy to think of it as a small piece of cloud that behaves with the logic of the cloud but is closer to the user. In edge computing, data is processed by the device itself or by a local computer or server, rather than being transmitted to the data center. The cloud works with exactly the same logic as the edge, but is on average much further away, so it has much slower response times.
Edge computing vs cloud comptuting.
This model that today increasingly represents an integration of cloud computing. was born because in some cases it is not convenient for companies to collect data at home, transfer them to large new suppliers and wait to receive the processed data. For three reasons. First, because broadband is not always so broad, and therefore there may be communication problems in some areas of the globe where even the mobile band does not arrive. Second, because the latency times, that is the reaction speed can be critical in some situations. Not always relying on datacenters located in places very far from each other is the best solution for a company in case of accidents. And then there is the issue of privacy. By increasing the objects connected with the IoT, the information that must be protected also increases. One way is not to transfer them all to the cloud but to keep them where they were produced, locally.

5G networks and edge computing.
5G networks have been designed, among other things, to reduce communication latency. 5G networks have lower latency than the previous generation. But, edge computing is critical to further reducing communications latency to the point where you don’t feel the difference from cable connections. To understand, the impulse that goes from the brain to the hand is under 10 ms. With 5G and edge computing you can emulate these speeds. When the application that needs particularly low latency is activated, the data and / or the application itself migrates closer to the user. This way, everything works faster, with minimal response times. If the user moves, the data moves with him to the nearest edge. This ensures that everything happens as reliably and quickly as possible
The promise of edge computing.
This at least on paper. But observers of “technological things” believe very much. According to a new “From Cloud to Edge” research, carried out by Reply with the proprietary Trend SONAR platform and the support of Teknowlogy Group, by 2025 cloud computing will lead the ict infrastructure market and edge computing will represent an exponentially growing market . In particular, the research examined the use of Cloud Computing and Edge Computing in the countries of the clusters “Europe-5” (Italy, Germany, France, Netherlands, Belgium) and “Big-5” (USA, United Kingdom , Brazil, China, India), in order to understand the evolution of the market. To be more precise, as the report indicates, by 2021, in both the “Europe-5” and “Big-5” clusters, the market for Infrastracture as a Service (IaaS) and Platform as a Service (PaaS) models will grow – regardless of the economic scenario – by 50% -55% compared to 2019.The Software as a Service (SaaS) market is also destined to grow at a rapid pace in all the countries analyzed. In particular, by 2025 it is expected to double in the USA, the United Kingdom and in all the countries of the “Europe-5” cluster and could increase up to four times in India and China.
