  • Cloud computing Network of servers on the Internet for sharing resources. Elastic resources i.e. we scale up or down the resources as per our demand.

  • *

    Cloud service Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)

  • *

    Cloud serviceSoftware as a Service (SaaS) Software on demand & subscription based licensing. E.g.: Microsoft Office 365, Google Apps etc.

    Advantages: No need to purchase software & their frequent updates. Eliminates the data center cost. High scalability.

    Disadvantages: Dependency on the service provider.

  • *

    Cloud servicePlatform as a Service (PaaS) Platform to develop, maintain and run applications without maintaining the infrastructure, middleware frameworks, database etc. E.g.: Windows Azure, AWS etc.

    Advantages: Various benefits in application testing & deployment. Backup & recovery as a part of service. Highly scalable and dynamic allocation based on geo-locations.

    Disadvantages: Data security Integrating PaaS with in-house systems.`

  • *

    Cloud serviceInfrastructure as a Service (IaaS) Infrastructure, dedicated or virtual servers. E.g.: Windows Azure, Amazon EC2 etc.

    Advantages: Various resources like firewalls, load balancer, VM disk image etc. Highly scalable infrastructure.

    Disadvantages: Off-premise data storage.

  • *

    Application features required for Cloud Architecture should not be specific to any topology Designed to take advantage of parallel architecture of cloud Design should consider the quantity of data transferred to the various clients (i.e. mobile, web etc.) as client may have limited bandwidth Data security is a major concern, so proper measures should be taken Service-Oriented architecture should be adopted

  • *

    Application migration planning Analyzed technically for performance, design, data security etc. Enterprise should consider the compliance issues, security concerns etc.

  • Queries....
