What is the underlying infrastructure used by Cloudhub?

The underlying infrastructure used by Cloudhub is based on EC2 AWS instances that run the Mule runtime. This setup leverages Amazon Web Services (AWS) to provide a scalable, reliable, and secure environment for deploying applications. Cloudhub utilizes the elasticity and on-demand resource provision of AWS, allowing developers to focus on building and managing their applications without worrying about the underlying hardware.

This infrastructure enables automatic scaling, load balancing, and other cloud-native features that enhance the performance and availability of Mule applications. Moreover, using a cloud-based infrastructure like AWS ensures that users benefit from the extensive global network and redundancy provided by Amazon, which is crucial for high availability and disaster recovery.

The other options are not applicable in the context of Cloudhub. For example, on-premise servers would limit the flexibility and scalability that cloud solutions offer. Hybrid cloud solutions typically involve a combination of on-premises and cloud resources but do not specifically reflect how Cloudhub operates. Similarly, physical servers in data centers do not align with the cloud-centric architecture that Cloudhub employs. Thus, the choice of EC2 instances with the Mule runtime distinctly characterizes Cloudhub's infrastructure.
