Cloud Computing

The word “Cloud” most likely was derived from the image of Cloud that was commonly used for the Internet.

Cloud Computing basically means doing all or most of the computing in the Internet without relying on physical resources.

On-Premise Security

•Perimeter security at customer site (physical access)•Hardware appliance (firewall, router)•Third party softwares(proxy/firewall/router)

Private Cloud

•Hosted at an enterprise or a service provider site•Supports one customer•Does not utilize shared infrastructure•Connectivity over private network or internet•Suited for information that needs a high level of security

Private CloudStandalone Private Cloud

Extend your existing office network

Replication for Disaster Recovery

Public Cloud

•Hosted at a service provider site•Supports multiple customers•Often utilizes shared infrastructure•Supports connectivity over internet•Suited for information that is not sensitive•Can be cheaper than private cloud

Software as a Service (SaaS)

The customer use the provider’s applications on a cloud infrastructure with little to no control over the infrastructure, network, servers, operating systems, storage,etc.

Platform as a Service (PaaS)

Customer deploys applications using an application development environment and middleware capabilities for specific languages eg java. and doesn’t control infrastructure, servers, OS, or storage but has control over the apps.

Infrastructure as a Service (IaaS)

Customer gets processing, APIs, storage, networks, and computing resources from the provider using his own OS, applications and may be some networking components.

Hybrid Cloud

Combination of public and private clouds bound together by either standardized or proprietary technology that enables data and application portability

Customers can decide on what data and applications should reside within and be run in the internal private cloud and which should be moved to the public cloud.

Deploying Applications in public cloud

• Licensing•Processing requirements and memory locks•Bandwidth requirements•Communication protocol•Data security

Security Considerations

•Perimeter extension•Identity and access management•Management tools•Data migration•Security policies

Security Best Practices

•VM-level security•Multi-layered defense•Traffic control•Data and encryption•Security control•Regulatory compliance
