Cloud Service Models

SaaS
NIST definition of Cloud Computing
 Cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool
of configurable computing resources (e.g., networks,
servers, storage, applications, and services) that can be
rapidly provisioned and released with minimal
management effort or service provider interaction.
Cloud Service Models

 Software as a Service (SaaS)

 The ability given to the end users to access an

application over the internet that is hosted and

managed by the service provider.
 The consumer does not manage or control the

underlying cloud infrastructure including network,

servers, operating systems, storage, or even
individual application capabilities, with the possible
exception of limited user-specific application
configuration settings.
 e.g: Google Apps, Microsoft office 365,

Cloud Service Providers

 VMware:
 A leader in Virtualization technology
 It came up with enterprise cloud computing solutions
 Currently it is providing a range of products for the
development of private and public clouds and for leveraging
the services offered by both as a hybrid cloud such as
 VMware vCloud Director
 VMware vCloud Datacenter service
 VMware vSphere
 VMware vShield
 vCloud Express
Cloud Service Providers

 Private clouds enable the better usage and management of

internal IT infrastructure than the traditional methods. Greater
operational efficiency, secure, fault-tolerant, well-managed
computing environments can be modeled and operated.
 VMware’s private cloud offering provides greater
standardization, rapid provisioning, and self-service for all
applications and unparalleled cost savings by consolidating
their physical infrastructures.
 VMware’s modular technology enables the user to select from
a variety of hardware, software, and certified service providers
to result in efficient cloud computing. Thus, the family of
products offered by VMware promotes compatibility and
retains the choice of freedom for the users to obtain desired
services.
Cloud Service Providers

 Private clouds can be created by using the VMware vSphere

and VMware vCloud Director.
 VMware vSphere is a robust virtualization platform used to
transform IT infrastructures into virtual storage, compute, and
network resources and provide them as a service within the
organization.
 VMware vSphere provides services at both the infrastructure
and application levels.
 At the infrastructure level, it provides options to perform
efficient operation and management of the compute, storage,
and network resources.
 At the application level, service-level controls are provided for
the applications running on the underlying infrastructures,
leading to available, secure, and scalable applications.
Cloud Service Providers

 The VMware vCloud Director, coupled with VMware

vSphere, is a software solution that enables
enterprises to build secure, multitenant private clouds
by pooling infrastructure resources into virtual
datacenters and exposing them to users through web-
based portals and programmatic interfaces as fully
automated, catalog-based services.
 VMware vCloud Director abstracts the virtual

computing environment from the underlying

resources and provides a multitenant architecture that
features isolated virtual resources, independent
LDAP authentication, specific policy controls, and
unique catalogs.
Cloud Service Providers

 The VMware vCloud Director allows users to catalog

infrastructure and application services of the desired
configurations and deploy and consume them as
needed. Interactions with the virtual data centers or
the catalogs are through a user-friendly web portal or
the vCloud API.
Cloud Service Providers

 VMware vShield technologies are used to provide

security to these environments by using services like
perimeter protection, port-level firewall, NAT and
DHCP services, site-to-site VPN, network isolation,
and web load balancing.
Cloud Service Providers
 Public and hybrid cloud solutions are provided by VMware by
partnering with other companies, certified as service
providers.
 VMware vCloud Datacenter Services and VMware vCloud
Express offer efficient solutions
 utilizing IaaS either as a public cloud or a hybrid cloud.
vCloud Datacenter Services provides a scalable environment,
where internal resources are augmented with the external
resources. vCloud Datacenter Services are built on the same
technology and foundations as VMware vCloud Director and
VMware vSphere to enable interoperability between cloud
environments.
 Thus, the user is free to burst his private cloud into public
cloud of his preferred service provider.
Cloud Service Providers
 vCloud Express is an IaaS offering delivered by leading
VMware service provider partners.
 It is a cobranded service that provides reliable, on-demand,
pay-as-you-go infrastructure.
 The VMware vCloud Express providers are Virtacore vCloud
Express, Hosting.com, Melbourne IT, and Terremark’s vCloud
Express.
 Instance types, load balancing, storage options, and pricing
vary between service providers.
