We already know that private cloud is mainly for enterprise users.For security reasons, enterprises prefer to store data in the private cloud, but at the same time hope to obtain the computing resources of the public cloud.Hybrid cloud integrates public cloud and private cloud, which is the main mode and development direction of cloud computing in recent years.In this case, hybrid cloud is more and more adopted. It mixes and matches public cloud and private cloud to obtain the best effect.
Hybrid cloud provides a cost-effective way for enterprises to expand storage. The cost of cloud storage is much lower than that of equivalent local storage. It is a good choice for backup, VM replication and data archiving.In addition, increasing cloud storage has no front-end costs and local resource requirements.
Although cloud computing does not guarantee that services will always be normal, public clouds usually have higher availability than most local infrastructure.The cloud has built-in redundancy and provides geo replication of key data.In addition, technologies such as Hyper-V replica and SQL Server AlwaysOn availability group allow us to use cloud computing to improve HA and Dr.The cloud also provides almost ubiquitous connectivity, enabling global organizations to access cloud services from almost anywhere.
One of the biggest benefits of hybrid cloud is flexibility.Hybrid clouds enable you to migrate resources and workloads from local to cloud and vice versa.For development and testing, hybrid cloud enables developers to easily handle new virtual machines and applications without the assistance of it operation and maintenance personnel.You can also use a hybrid cloud with elastic scalability to extend some applications to the cloud to handle peak processing requirements.The cloud also provides a variety of services, such as BI, analysis, Internet of things, etc. you can use these services at any time instead of building them yourself.
It unifies the hybrid cloud platform, realizes the unified operation and maintenance management of resources, and effectively improves the utilization rate of resources.
It uses a hybrid cloud to build a data center, in which the hosting cloud realizes asset light operation.Therefore, the investment in data center equipment, operators and sites is greatly reduced, and the overall construction cost of the data center is reduced.
It constructs a unified security system and realizes stronger information security protection through the construction of data security, platform security, application security and network security.
Many applications can be deployed in hybrid. Both Hyper-V replica and SQL Server AlwaysOn availability group have built-in cloud integration functions.New technologies such as the stretch databases function of SQL server also enable you to deploy databases from within to the hybrid cloud.
