Public Cloud: Infrastructure and control with service provider. SaaS

Private Cloud:Infrastructure held by owner, but control is with the customer. IaaS is the main service.

Hybrid Cloud:Mixture of public and private cloud that yields the most benefit.

IaaS: It is the delivery of computer infrastructure as a service.

PaaS: It delivers a computing platform or solution stack as a service

SaaS: On-demand software, hosted on the cloud.

Services and Architectures

Cloud: Prospects and Opportunities [4,6,7]

Traditional In-house system implementation

Cloud services in the form of SaaS, Paas and IaaS

1. High CapEx 1. OpEx oriented

2. Time required to implement the system

2. Comparatively low startup cost

3. Maintenance Cost 3. Pay for what you use

4. Equipment depreciation 4. Low maintenance cost

5. Dedicated staff for 24 * 7 support

5. Scalable and secure environment

6. Under-utilized resources 6. Business companies can focus on business development, not on IT.

Rendezvous with new challenges

Virtualization in Cloud

-Using KVM [Kernel Virtual Machine] run multiple virtually independent operating systems.- Using XEN hypervisor, run virtual machines n the physical ones that do not support virtualization (in progress).

Security in cloud:

-Identify areas of security breach.-Analyze the security faults of cloud providers like Amazon EC2.-Learn about Trusted Computing.

Openbravo ERP

-Setting up the Openbravo ERP in ubuntu server.-Integrating ERP with Postgresql-Linked the ERP with tomcat and built it from source.

Functional Requirements:

Functional Requirements

Description

1. Compatibility

Must comply with the third-party cloud management.

2. Monitoring System resources, instances monitored for dead/alive.

3. Provision Flexibility

Based on QoS resources should be allocated.

4. Multiple instances

Supplementary information displayed with the instance, emi-id, eri-id, eki-id.

5. Scalability During greater demand for resources, new nodes can be registered with major changes.

6. Dynamic ip address

Instances should be assigned ip addresses dynamically from the range of public addresses.

Midterm presentation 14

Non-functional requirements

Non-functional requirements

Description

1. High availability System uptime is 180 [120 seconds is standard [3], so we get 88% uptime] seconds, instance launching time is 1.00 second.

2. Security SLA agreement must be followed.

3. Cost efficiency Maximum 30% costs should be saved.

4. Intelligent Management

Reporting about the instance behavior and pattern of use.
