Cloud computing has evolved in past years and with rising customer needs the organizations are exploring multiple options to meet the demands and this has given rise to one of the most used Cloud Computing Technology i.e. Hybrid Cloud. It’s a type of computing environment that combines Public and Private clouds to reap the benefits of both. An Application and all its components share the resources between one or more public clouds such as Amazon Web Services (AWS), Microsoft’s Azure, etc. and private clouds, on-premises infrastructure. Hybrid Cloud technology provides greater flexibility by leveraging the public cloud for high computing needs and private cloud for sensitive and business-critical workloads. Hence, it’s often-called “Best of Both Worlds”.
Hybrid Cloud Architecture:
There are mainly 2 types of architecture monocloud and multicloud.
- Monocloud: In this type of model usually a single Public Cloud Provider is chosen which is connected to On-premises infrastructure. The two environments are connected to form a single hybrid environment. It is usually the first step in the Hybrid Cloud journey.
- Multicloud: In this type of model multiple Public Cloud Providers are chosen which are connected with On-premises infrastructure. This provides greater flexibility to organizations to extract the best from each Public Cloud and also avoid vendor lock-in situations by moving the workloads from one provider to another.
Hybrid Cloud Use Cases:
The Hybrid Cloud has many business Use cases some of them are:
- For critical Workloads: When workload is critical, we can use the public cloud for less sensitive and private cloud for more sensitive information.
- For Dynamic Workloads: When workload is dynamic, we can use Public cloud for highly scalable workloads and private cloud for less scalable workloads.
- Hosting new applications: If the organization is not solely built on Public Cloud there would be the vast majority of applications running on on-premises and they can leverage hybrid cloud for hosting new applications because the upfront cost is less. After all, they don’t have to buy all the hardware in Datacenter to host application but consume and pay for services they consume from cloud providers, hence cost is significantly reduced for new application hosting.
Hybrid Cloud Benefits:
Below are the benefits of the Hybrid Cloud but are not limited to the following points only.
- Reduced cost: No upfront cost to buy all the hardware, just pay for the services you consume.
- Improved Agility and Scalability: It provides business greater control over the data and reduces the application time to market by meeting all the business demands.
- Improves Business Continuity: As its often-called Best of Both Worlds, in case of disaster, the business operations will continue to run without interruption.
- Security and Compliance: Organizations need to adhere to regulations and compliance guidelines. They can still keep their data secure and complaint by storing critical information in private cloud and still leverage the power of the public cloud.
