Hybrid cloud is a cloud computing strategy, in which a user uses a combination of cloud environments- generally private and public cloud, however it may include any combination of on-premises, co-located or virtualized infrastructure- with coordination between them. According to IBM, Hybrid clouds primarily work on an infrastructure and application level.
On an infrastructure layer, a hybrid cloud is the combination of virtual machines from various cloud services. On a software as a service layer, a hybrid cloud defines an app setup with component in various SaaS offerings or existing apps within the data center of a company.
Benefits of Hybrid Cloud
The hybrid cloud combines the advantages of both the public and private cloud. It offers the public cloud’s easy access and fast connection along with high security features of the private cloud.
Improved flexibility and agility
Flexibility is another important benefit of the hybrid cloud. The hybrid cloud allows users to move workloads and resources from on-premises to the cloud and vice versa. If we talk about development and testing, then the hybrid cloud allows developers to install new applications and VMs without requiring intervention from IT operations. Organizations also find cloud bursting capability of hybrid cloud very useful as it allows one to extend portions of their apps into the cloud to tackle peak processing requirements. The cloud also provides an array of services like IoT, analytics and BI that you can use readily for your new projects.
Increased accessibility and availability
Although they don’t deliver 100% uptime, public clouds like Amazon and Azure generally have better availability rates as compared to most of the local IT setups. The cloud has the ability to offer geo-replication of your important data as well as has in-built redundancy. Additionally, technologies like Hyper-V Replica and SQL Server Always On Availability groups allows organizations to use the cloud for improved HA and DR. The cloud also provides reliable connectivity allowing users to access cloud services from almost everywhere.
Increased scalability and storage
The hybrid cloud also provides a very cost-efficient solution for organization to increase their storage capacity. Cloud storage generally cost comparatively less than the same capacity of on-premise storage. It is worth mentioning that cloud storage generally don’t deliver the same level of performance as local storage, but it can be great option for backups, architecture data and replicated VMs.
Decreasing costs is one of the primary benefits of the hybrid cloud. It is also one of the biggest factors that compel organizations to consider these services. The incremental pricing of adding capacity physically in premises is high, as it involves the additional cost to purchase power, storage, servers and in some cases creating completely new data centers. The hybrid cloud allows companies to decrease costs. One doesn’t have to purchase these local resources, when going for the pay-as-you-go services of cloud.
