The document discusses hybrid cloud computing, which combines private and public clouds to offer cost-effective solutions, disaster recovery, and seamless application integration. It highlights the benefits of hybrid cloud, including enhanced security, improved access, and efficient resource management amidst varying computing demands. The author emphasizes the importance of considering hybrid setups in future IT strategies, as identified by Gartner as a key technology trend.

1. Hybrid Cloud Is The Best Option?

Hybrid Cloud is not a household term yet. It’s simply a
combination of the Private Cloud together with the Public Cloud.
Hybrid Cloud enables IT to utilize on-premise and cloud based
infrastructure seamlessly for cost reduction, bursting, disaster
recovery and other use cases. The key to Hybrid Cloud acceptance
in the marketplace is providing this “seamless” capability for all
applications, including those production applications that are core
to the business.
Types of cloud computing
 Public Cloud: In Public Cloud the computing infrastructure is hosted by the cloud
vendor at the vendor’s premises. The customer has no visibility and control over
where the computing infrastructure is hosted. The computing infrastructure is shared
between any organizations.
 Private Cloud: The computing infrastructure is dedicated to a particular organization
and not shared with other organizations. Private Clouds are more expensive and more
secure when compared to Public Clouds. Private Cloud is what used to be called your
company network. It may be accessed whilst inside the firewall, or outside via some
form of secure VPN. But it is a resource controlled and consumed by your internal IT
department.
 Hybrid Cloud: Organizations may host critical applications on Private Clouds and
applications with relatively less security concerns on the Public Cloud. The usage of
both Private and Public Clouds together is called Hybrid Cloud. A related term is
Cloud Bursting. In Cloud Bursting organization use their own computing
infrastructure for normal usage, but access the cloud using services like Salesforce
cloud computing for high/peak load requirements. This ensures that a sudden increase
in computing requirement is handled gracefully.
Hybrid Cloud Is The Best Option?
The Public Cloud brings Simplicity while the Private Cloud means better Privacy, but Hybrid
Cloud combines the best of both worlds: Keep all important corporate data secure behind some
Private Cloud-based service on stored securely using an array of on-premise servers, while
access to that data remains tightly controlled and accessed through a combination of SaaS and
DBaaS (Cloud database) services. This provides the best of both worlds: mobile and web-based
access to corporate applications with high usability, while important data remains secure.

2. The Future?
Gartner Identifies Hybrid Cloud as one of the Top 10 Strategic Technology Trends for 2014
“Bringing together personal clouds and external private cloud services is an imperative.
Enterprises should design private cloud services with a hybrid future in mind and make sure
future integration/interoperability is possible.”
