Google App Engine
PaaS cloud that provides a complete Web service environment: All
required hardware, operating systems, and software are provided to
clients. Thus, clients only have to focus on the installation or creation of
their own services, while App Engine runs the services on Google’s
servers.
App Engine only supports the Java and Python programming languages.
Microsoft Windows Azure
Another PaaS cloud, Microsoft’s Azure [4] allows clients to
build services using developer libraries which make use of
communication, computational, and
storage services in Azure and then simply upload the
completed services.
To ease service-based development, Azure also provides a
discovery service within the cloud itself. Called the .NET
Service Bus .

- 2. Introduction The emergence of cloud computing has caused a significant change in how IT infrastructures are provided to research and business organizations. Instead of paying for expensive hardware and incur excessive maintenance costs, it is now possible to rent the IT infrastructure of other organizations for a minimal fee. While the existence of cloud computing is new, the elements used to create clouds have been around for some time. • Elements to create cloud • Large-scale clusters • Virtualization • Service Oriented Architecture (SOA) • Web Services • CaaS • Cluster as a Service • Related Work • Amazon EC2 • Google AppEngine • Microsoft Azure • Salesforce Cloud Computing - Part II 2 30th Jan,2020 2
- 3. 30th Jan,2020 Amazon EC2 An IaaS cloud, EC2 offers “elastic” access to hardware resources that EC2 clients use to create virtual servers. Inside the virtual servers, clients either host the applications they wish to run or host services of their own to access over the Internet. As demand for the services inside the virtual machine rises, it is possible to create a duplicate (instance) of the virtual machine and distribute the load across the instances. •EC2 is its low level of abstraction. clients have to create a virtual machine, install software into it, upload the virtual machine to EC2, and then use a command line tool to start it. •Amazon announced new scalability features, specifically Auto-Scaling and Elastic Load Balancing . * Finally, EC2 does not provide any means for publishing services by other providers, nor does it provide the discovery and selection of services within EC2. After services are hosted inside the virtual machines on EC2, clients are required to manually publish their services to a discovery service external to EC2. Cloud Computing - Part II 3

- 5. 30th Jan,2020 Salesforce 1. SaaS cloud that offers customer relations management (CRM) software as a service. Instead of maintaining hardware and software licenses, clients use the software hosted on Salesforce servers for a minimal fee 2. Salesforce is only applicable for clients who need existing software. 3.Salesforce only offers CRM software and does not allow the hosting of custom services. 4. the greatest ease of use, Salesforce has the least flexibility.

RVWS Design • Problem • To know if the resource(s) behind the Web service is (are) ready • Solution • Resource Via Web Service (RVWS) framework • A single, effective, service-based framework • Combines • dynamic attributes • stateful Web services (aware of their past activity) • stateful and dynamic WSDL documents • brokering Cloud Computing - Part II 30th Jan,2020 6
- 7. Dynamic attributes- 2 categories • State attributes • cover the current activity of the service and its resources, thus indicating readiness. • Characteristic attributes • cover the operational features of the service, the resources behind it, the quality of service (QoS), price and provider information 27 November 2012 Cloud Computing - Part II 4 30th Jan,2020 7
