What is Hybrid Cloud：
Hybrid cloud combines public and private clouds, which is the main mode and development direction of cloud computing in recent years. We already know that private clouds are mainly for enterprise users. For security reasons, enterprises are more willing to store data in private clouds, but at the same time they want to get public cloud computing resources. In this case, hybrid clouds are getting more and more More adoption, it mixes and matches public and private clouds to get the best results. This personalized solution is both cost-effective and secure.
Interestingly, it is not that private and public clouds are separate, but private and public clouds work together. Here’s a classic example: using storage, database, and service processing in a private cloud, while leveraging the public cloud to complete data processing needs during peak demand periods without having to purchase additional hardware. Many companies have evolved toward this cloud-bursting architecture, and this is also the key to maximizing benefits.
Because the public cloud only charges you for the resources you use, the centralized cloud will become a very cheap way to handle demand spikes. For example, for some retailers, their operational needs will increase dramatically with the arrival of holidays, or some businesses will have seasonal rises.
At the same time, hybrid clouds also provide a good foundation for the elastic needs of other purposes, such as disaster recovery. This means that the private cloud uses the public cloud as a platform for disaster transfer and uses it when needed. This is a very cost-effective concept. Another good idea is to use the public cloud as an alternative platform while choosing other public clouds as a disaster transfer platform.
Advantages of hybrid clouds:
Hybrid clouds offer many important features that can benefit businesses of all shapes and sizes. These new capabilities enable organizations to leverage the hybrid cloud to extend their IT infrastructure in ways never before possible. Let’s take a look at the five advantages of hybrid clouds.
Reducing costs is one of the most attractive advantages of cloud computing and an important factor driving enterprise management to consider cloud services. The incremental cost of upgrading a pre-built infrastructure is high, and the increased provisioning of computing resources requires the acquisition of additional servers, storage, power, and the need to create new data centers in extreme cases. Hybrid clouds can help companies reduce costs and use “pay as you go” cloud computing resources to eliminate the need to purchase local resources.
Hybrid clouds provide a cost-effective way for enterprises to scale storage. The cost of cloud storage is much lower than that of equivalent local storage, making it a good choice for backing up, copying VMs, and archiving data. In addition, increasing cloud storage has no upfront costs and local resource requirements.
Improved Availability and Accessibility
While cloud computing does not guarantee that services will always be normal, public clouds are often more usable than most local infrastructure. The cloud has built-in redundancy and provides geo-replication of critical data. In addition, technologies such as Hyper-V replicas and SQL Server AlwaysOn availability groups allow us to leverage cloud computing to improve HA and DR. The cloud also provides an almost ubiquitous connection that allows global organizations to access cloud services from virtually any location.
Improved agility and flexibility
One of the biggest benefits of hybrid clouds is flexibility. Hybrid clouds enable you to migrate resources and workloads from the local to the cloud and vice versa. For development and testing, Hybrid Cloud makes it easy for developers to get new virtual machines and applications without the assistance of IT operations staff. You can also leverage a hybrid cloud with elastic scaling to extend some applications into the cloud to handle peak processing needs. The cloud also offers a variety of services, such as BI, analytics, the Internet of Things, etc. You can use these services at any time instead of building them yourself.
Beneficial to Application Integration
Many applications offer built-in hybrid cloud integration. For example, as mentioned earlier, Hyper-V replicas and SQL Server AlwaysOn availability groups have built-in cloud integration capabilities. New technologies such as SQL Server’s Stretch Databases feature also enable you to deploy databases from the inside to the cloud.
