Cloud is no more a new technology today, but it is has evolved as complex ecosystem in the last few years. When it comes to understanding basics of cloud computing services- they are offered in Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) models. The deployment methods include private, public and Hybrid, says Ravi Namboori, Director of Architecture at Equinix.
Hybrid Cloud is now the most preferred model for majority of the global enterprises as it blends both private and public clouds. It enables user enterprises to run their mission critical data and applications in on-premise private cloud while allowing them to move bursty or non-critical data on to public cloud.
Though cloud has been rapidly evolving year-over-year, enterprises from banking and financial sectors are reluctant to opt for cloud due to the compliance and security concerns. But with hybrid evolution these institutions are gradually getting inclined towards cloud adoption in the recent years, adds Ravi Namboori a data center expert.
Hybrid cloud can be offered as hybrid IaaS, hybrid SaaS or hybrid PaaS and each of these models brings significant value addition for highly fluctuating or dynamic workloads.

Hybrid SaaS blends on-premise software applications with third party SaaS solutions to enable enterprise leverage best from the SaaS services associated with enhanced security and user control.
Functionally, the third party cloud service provider enables user to log in to cloud application from web browser and accesses the cloud environment which includes mechanism, functionality and user interface.
Hybrid SaaS gives full flexibility and control to the user organization to store their data in their private data storage or on cloud. With these model user enjoys more control on their data storage with enhanced security while leveraging best benefits from the cloud services.
The real challenge lies in adopting right cloud offering, enterprises need to have thorough understanding of their unique business needs. However the most common needs to adopt cloud remains same for all the organizations which typically includes broad access, elasticity, resource pooling and scalability.
In modern day business scenario, needs are unique and change very often which signifies the enterprises to be flexible enough to scale infrastructure as per changing needs. Cloud computing has become very advanced today to ensure secure communication and information sharing.
Modern day cloud evolved as a complex powerful solution that enable enterprises to handle internal and external collaboration, manage critical processes and complex transactions efficiently, adds Ravi Namboori a Cisco evangelist.
