Cloud Computing – NIST Definition:

“A model for enabling 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”

Three Service Delivery ModelsIaaS: Infrastructure as a Service

Consumer can provision computing resources within provider's infrastructure upon which they can deploy and run arbitrary software, including OS and applications, alike Rent a virtual server, Exp. : Amazon, Rackspace, GoGrid, etcPaaS: Platform as Service

Consumer can create custom applications using programming tools supported bythe provider and deploy them onto the provider's cloud infrastructure. Alike rent an abstract machine, Exp. : Google app engine, Salesforce, etc

SaaS: Software as ServiceConsumer uses provider’s applications running on provider's cloud infrastructure. Alike rent a capability, Exp. : Exchange hosting, Wordpress hosting, etc.

XPBagaimana Cara Kerja SaaS


XPContoh Arsitektur SaaS


XPSaaS Delivery Model


XPPerkembangan SaaS• First Generation

– Application Service Providers attracted attention to web-based access to software vendor applications

– Hindrances were: slowness of economy, reduced IT spending, “customization trap”, competition among the firms

• Second Generation– Select group of firms continued through improving

imperfections and validating business model • Evolving Business Concept

- Increased user subscription and sales growth- Possibility of more functionality


XP

SaaS Menjadi Bisnis Model Baru• Mobile models – any PDA

– Deliver to screen format in use

• Working out‐of‐office – Real Estate Agents• Salespeople who visit the client

– Build the plan and place the order there

• Hot‐desking• Virtual Organisations• Franchise models.

Focus on Smaller Upgrades

Constant, Smaller Upgrades

Predictable Revenue Stream

Shorter Implementation Time

Collective Operating Environment

No Client/Server software Installation & Maintenance

Provider SideClient Side


XPContoh SaaS• Viatel’s Webcontrol

– Offers protection from spyware, web viruses, phishing, unwanted content and adwarethrough filtering

– Requires no hardware, maintenance or upfront capital costs

– Redirects all corporate web traffic with its dedicated servers then analyzes it before displaying the content to the end‐user


XPContoh SaaS

• LitwareHR by Microsoft– fictitious HR application providing recruitment‐management software delivered as a service

– created to demonstrate how to use Microsoft technologies in the creation of SaaS solutions

– uses Microsoft technologies such as .NET Framework 3.0 and SQL Server 2005


XPBagaimana SaaS Kini?

A factor in faster adoption of Service Oriented Architecture

SaaS vendors have begun selling to a new audience

Connecting information todashboards & transaction systems

SaaS will no longer be called “as a service”, but as a

software

Overly complex and opaqueLicensing/pricing
