Instead of maintaining stationary databases, more and more companies are switching to cloud solutions. The advantages are obvious: instead of a cost-intensive and power-hungry server on site, the company’s own data is outsourced.
In addition to complete relocation to the private or public cloud, there are also hybrid models that leave part of the data in-house in addition to the cloud. This can be a smart approach, especially for particularly large data sets. The costs incurred can usually be estimated well and are not subject to strong fluctuations. There is no need to purchase or update expensive hardware or software. Linking different sites is also easier with a cloud model.
All of these open source databases are also suitable for full or hybrid cloud deployment. If you opt for a cloud solution, you are probably also interested in highly scalable databases. At the same time, you want fast response times, since the connection to the cloud can cause slight latencies anyway. This is where Apache Cassandra and Redis come into play, as these two database systems are both highly scalable and impress with their great performance.
