Of course, this has a positive impact on performance. It’s no wonder, then,

that the use of Hybrid Cloud solutions has increased by 7% in a single year, from
2018 to 2019 (source: RightScale). In addition, 58% of companies now have a
hybrid cloud computing strategy (also according to RightScale).

The Multi-cloud is something very similar to the Hybrid: it is the use of different
Cloud Computing and data storage systems within a single IT architecture. There
can be multi-cloud systems based only on public systems, only on private systems
or, finally, on a combination of hybrid systems.

2. Serverless

“Serverless,” also known as, FaaS (Function as a Service) is one of the main
Cloud Computing trends.

First of all, don’t be fooled by the name: one or more servers for processing
operations are always essential, upstream of everything. The real innovation of

these systems is the possibility to run applications without worrying about the
underlying infrastructure. Translated: provisioning, scalability, and server
management are automatically administered, with enormous advantages for
flexibility and performance.

The first serverless model was released by Amazon in 2014 (known as AWS
Lambda); Microsoft, IBM, and Google soon followed with their own serverless
offerings. Serverless solutions were used by 21% of companies in 2018.

Compared to the previous year, serverless grew about 75% (source).

3. New Backup and Disaster Recovery Systems

One of the most important advantages of Cloud Computing is the efficiency and
elasticity of the Backup and Disaster Recovery systems (a term used to identify
all recovery measures relating to data, systems or infrastructures).

According to a recent Spiceworks report, 15% of the cloud budget is invested in

improving this fundamental aspect.

That’s why all major cloud service providers (public, private or hybrid) are
working hard on this front.
