One of the main trends of the current IT departments is to reduce the size of the data centers of their companies to the maximum, transferring workloads from their local environment to public clouds like those of Amazon, Microsoft or Google, mainly.
To do this, most opt for a hybrid cloud architecture in which they use one of the named public clouds, making use of SaaS and their local systems.
It is therefore a complex architecture, with different systems and some challenges to cope with such as connectivity, scalability, visibility and control.
But how to know if your case is the same as that of others? How, when and why should you use a hybrid cloud solution in your company?
A hybrid cloud is a cloud environment where a company uses both a local cloud and a public cloud to run its applications. There are three main use cases where such a configuration benefits a business.
The hybrid cloud allows customers to deploy applications in the right cloud based on the characteristics of the application. Some applications fit into more than one category. For example, if you have an elastic application that needs a local workload, you may have to sacrifice the locality and execute it in a public cloud.
Many companies are cyclical in nature, and their scale of application and infrastructure requirements can vary dramatically from month to month. The base workload can be executed in a local infrastructure and scaled in a public cloud to meet demand peaks.
Consumption of Services in the Cloud
Many applications use different services. For example, an application that provides data exchange between delegations can use object storage in the cloud as a reliable store and to share data. Here, the local application can be deployed with a certain amount of caching, but the cloud can be used as a primary data store.
Key Technical Challenges
There are several technical challenges in creating a hybrid cloud solution. One of the key components is the connectivity between the two clouds, and the second key component is the orchestration layer to deploy workloads across multiple clouds.
These are just basic things to which you have to pay attention when it comes to hybrid cloud. These and many other useful things about this topic and similar ones you will find on aviatrix.
