What is Hybrid Cloud? 🧐
Before answering this, a quick overview of public and private clouds.
A public cloud offers cloud computing services to public and allows anyone to buy them which can be charged based off the usage. The actual cloud provider is responsible of maintaining the hardware required for a public cloud keeping it’s users free to bother about the resources that they pay for.
A private cloud is when cloud providers restrict the usage of their services to certain users either over internet or some private network.
A Hybrid cloud combines both private and public cloud i.e. an on-premise private cloud datacenter offering can be combined with public cloud for the exchange of data.
A hybrid cloud doesn’t mean using some of both, public as well as private services. Instead it means using public and private services together.
When the usage increases that aren’t being handled by private cloud services and they need to scale up, public cloud can be used to instantly scale up the services without being concerned about the cost and hassle of installing them privately. In addition to this, the additional computing power needn’t be maintained privately and allows easier maintenance of resources that are rarely used.
Compatibility between private datacenters and public services.
Security issues since data will be moved across private & public cloud.
If there’s excessive movement of data, this could lead to egress costs to rise up quickly.
Securely maintaining the access using authentication & authorization.
