At this point, no one doubts that cloud computing is here to stay. Little by little, the inherent advantages of their nature have motivated many companies, even those from sectors that have little or nothing to do with technology, to take the step towards more flexible, secure and scalable infrastructures. Here is emphasized the concept of hybrid cloud and explained why it is an increasingly relevant and more represented concept.
A hybrid cloud is the combination of one or more public and private cloud environments, so that business organizations benefit from the advantages provided by the two types of cloud infrastructure. Thus, there is a set of virtual resources managed by administration and automation software that allows users to access what they need.
Although the concept of hybrid cloud can give the overall idea, it is important to emphasize that the public and private cloud environments that make up the hybrid cloud are unique and individual entities. An application programming interface (API) is responsible for transferring resources and workloads from one cloud to another, keeping the most critical workloads in the private cloud and taking advantage of the potential of the public cloud to optimize costs.
There are many ways to deploy a hybrid cloud, but the fundamental basis of all of them is interoperability. Without contact between the two infrastructures, public and private cloud can exist and be used by the same organization, but it can not be considered a hybrid cloud.
Hybrid clouds have several points of contact, controlled by an API, and are composed of software solutions in charge of controlling and managing the migration of workloads, the deployment of resources, the integration between platforms and the execution of applications.
In addition to interoperability and control capability, scalability is an inherent feature of a hybrid cloud that can grow horizontally (scale out), adding processing units based on workloads, and vertical (scale out), releasing more resources to existing processing units.
Although the hybrid cloud comes to solve many of the problems posed by infrastructures based on a single cloud, public or private, its adoption is not without challenges that must be taken into account. These are some of the most relevant: the availability of services and processing capacity of non-critical workloads depends on the cloud service provider; the data goes through different instances (public, private or both) until it reaches its destination, which can increase security risks; the centralization of the administration and management of the hybrid cloud can cause technological dependence on a provider; the compatibility between infrastructures is a critical issue and can pose a change in the tools and solutions that not all companies are willing to take on; connectivity, as in any cloud infrastructure, plays a fundamental role. With a hybrid cloud, it is not only important to guarantee it within our organization, but also with the public part of our cloud.
