This provides a good understanding about hybrid cloud computing and also other cloud computing architecture and about the security of hybrid cloud computing.

1. Data Security In Hybrid Cloud Computing

2. What is cloud
It is a type of Network-based computing where different services --
such as servers, storage and applications -- are delivered to an
organization's computers and devices through the network by
sharing computing resources.

3. Cloud computing should be
Agile
Flexible
Scalable Secure
Cost
Effective

4. Types of Cloud
Public Cloud
Private Cloud
Community Cloud
Hybrid Cloud
the services are rendered over a network that is open
for public use.
It is operated solely for a single organization, managed
by internally or a third Party
It shares infrastructure between several organizations
from a specific community with common concerns
It is a composition of two or more clouds
(private and community or public)

5. Hybrid Cloud Provides
Flexible

6. Security Concerns Of Hybrid Cloud

Privacy
Legal
issues

7. Identity management
Every enterprise will have its own identity management
system to control access to information and computing
resources. Cloud providers either integrate the
customer’s identity management system into their own
infrastructure, using federation or SSO technology, or
provide an identity management solution of their own.

8. Physical and personnel security
Providers ensure that physical machines are adequately
secure and that access to these machines as well as all
relevant customer data is not only restricted but that
access is documented.

9. Availability
Cloud providers assure customers that they will have
regular and predictable access to their data and
applications.

10. Application security
Cloud providers ensure that applications available as a
service via the cloud are secure by implementing testing
and acceptance procedures for outsourced or packaged
application code. It also requires application
security measures be in place in the production
environment.

11. Privacy
providers ensure that all critical data (credit card
numbers) are masked or encrypted (even better) and that
only authorized users have access to data in its entirety.
Moreover, digital identities and credentials must be
protected as should any data that the provider collects or
produces about customer activity in the hybrid cloud.

12. Legal issues
providers and customers must consider legal issues, such
as Contracts and E-Discovery, and the related laws, which
may vary by country.

13. Ways Of Providing Security
Proper encryption mechanisms
Proper log data recording system
Prepare security responsibilities properly and clearly
Maintain proper backups
Should have a good anomaly detection system

14. Drawbacks of Hybrid Cloud
Complex networking
Infrastructural dependency
Have to depend on service provider’s regulations
Implementing Cost is high
