What does a hybrid cloud mean?
As a business grows, one of the most important things that every business owner should care about is scalability. For being able to manage a lot of requests from customers, you definitely need to purchase more hardware. This means you need to bear an enormous expense for buying and implementing your new facilities. Previously, we discussed how private and public clouds solved this problem. At this moment, we are going to give you information about the specific environment that uses the mix of both of them named as a “hybrid cloud“.

If you are probably tasked to investigate how hybrid cloud could help your company’s goals or you are just a little bit curious about how this hybrid cloud approach works, you will find all your answers in this article in Digital-Goal.
As we mentioned above, the hybrid cloud is a type of cloud computing environment that connects on-premise (private cloud) and third-party (public cloud) in a way that makes the data transformation much more easer between these two cloud computing systems. It can increase scalability and flexibility at the same time.
On-premises VS Cloud computing
Before starting comparing these two, it is better to declare a general definition for On-premises clouds. On-Premises stands to private data centers that every company can have it for itself and save all of their records and data on that. Therefore, this can lead to a private cloud which only staff in that particular company and maybe customers are just able to use. Now, it is time to show what differences on-prem and cloud computation have.
1- In one hand, on-prem data warehousing and analytics are very complex. It also needs a very big budget and great amount of maintenance. On the other hand, cloud computing is affordable even to small businesses. It is also very flexible and available under any circumstances.
2- Because you have physical access to your data center, on-prem gives you good control. However, cloud systems could offer your agility. Costumers can also use pay-as-you-go method in order to utilize cloud computation services without any concern related to payment.
How does a hybrid cloud system work?
In fact, a hybrid app is divided into two distinct environments which are private and public environments. Both of them are working simultaneously to make the running of your applications possible. To make it more clear, let’s give an example:
let’s suppose we have a company which is running an air freight business. This company has an existing on-prem ERP (enterprise resources planning) application. They can use different application features to manage their cargoes and make sure that each consignee will be able to receive them on time. But what will happen if they want to produce a mobile application for their costumers?
In this specific case, developers decide to deploy the back-end of the mobile application on a public cloud. It can work seamlessly if the number of requests is not too many. However, when you are facing a large demand, the transition between public and private cloud could decrease the total performance of your system. This is exactly where a hybrid cloud plays a key role. Developers can put a small portion of the information on the public cloud and reduce transition steps between the private and public clouds significantly.
What does a hybrid cloud system consist of?
Overall, we can categorize all our requirements for implementing a hybrid cloud service like below:
- Public infrastructure as a service (IaaS) platform. These services could offer a variety of facilities which enterprise companies can take advantage of them. For example, compute instances, storage resource, big data analytics, etc. For instance, Amazon Web Services, Microsoft Azure, Google Cloud and Rackspace hosting are now presenting this service. The public cloud is connected to the internet for anyone to leverage.
- Private cloud infrastructure which could be provided by either company itself (on-premises) or a hosted private cloud provider. These environments can be connected to end-users over a private line or through the public internet.
- A tunnel that allows communication between private endpoints and public counterparts. Obviously, the speed of this tunnel (for example WAN) should be adequate enough to help these two environments work in tandem.
The technical team should be aware of how important is that these two cloud-based systems work in an interoperation way. That is why they always try to choose the best hypervisor and cloud software layers (like OpenStack and Docker) that are compatible with the desired public cloud. Put it in other words, to be ensured about systems are working properly, the technical team needs to make sure that there are no problems using cloud’s application programming interfaces (APIs) and also services.

In fact, market research studies show that over the next five years, hybrid cloud adoption will hit 43% of all businesses who are using any kinds of cloud computing. This number was less than 27% in 2013. Therefore, this is a significant trend to follow and it can open new doors in front of companies and startups in the future. Hybrid cloud is able to provide the best of the two worlds in one place. This architecture can help companies to leverage a private cloud uniquely for some of their applications and public clouds for others. Through this solution, they can leverage both types of infrastructures to support different types of use cases.
