Beyond Desktop : Introducing Cloud Computing

What is Cloud Computing "Cloud Computing", by definition, refers to the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing Cloud is essentially a flexible, scalable, pay-per-use model for the way IT services are delivered and consumed, typically through short-term contracts Model for usage-based network access to a common pool of configurable computing resources (e.g. networks, servers, storage systems, applications, and services) that can be provided and used quickly Cloud computing is a pay-per-use consumption and delivery model that enables real time delivery of configurable computing resources such as networks, servers, storage, applications and services. Typically these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. Cloud delivery models help organizations to scale their investments as they grow in business. They open the door to new business approaches through standardized applications.

Deployment Models of Cloud Computing Dedicated/ Control Secure Fixed Cost Reduced Risk Private Shared Open Pay-per use Public Pick from the best of both worlds Hybrid Public: An easily deployed virtual server on a shared hosting infrastructure. Quickly or automatically scale your servers according to work load. Pay-per-use for unlimited computing resource, storage and bandwidth. Choose a cloud with quality service, engineering and infrastructure. Choose carefully to avoid noisy neighbor effect from sharing. Owned by the service provider. Provides great level of efficiency. Private : Dedicated, Secure, Fixed Cost. A secure virtual data center on your own dedicated infrastructure. Servers and storage can be added and scaled according to your needs. Planned resource capacity with fixed costs and unmetered bandwidth. Financial control and quick IT response to business needs. Having IT control means you also need IT expertise and resources. Hybrid : Pick from best of both worlds. A mix of dedicated infrastructure and public cloud infrastructure. Cherry-pick the best infrastructure for your different services. Keep data secure and control costs and resources and dedicated infrastructure. Choose public or private cloud for each service according to its performance profile. Requires IT architecture planning, support and expertise !

Service Models for Cloud Computing Infrastructure as a Service (IaaS) : Virtual machine services accessed over the network, providing compute and/or storage capabilities Products offered via this mode include the remote delivery (through the Internet) of a full computer infrastructure (e.g., virtual computers, servers, storage devices, etc.) Provides a hardware platform as a service, such as Amazon EC2 or Oracle Compute Service Amazon Web Services, Google Compute Engine, Microsoft’s Azure Virtual Machines, Rackspace, GoGrid Platform-as-a-Service (PaaS) : Rapid Development at Low cost, private or public offering Provides organizations with a runtime environment to develop , maintain , manage the application Provides a software platform as a service, such as Google Apps Engine or Oracle Java Cloud Google App engine , Microsoft Azure, Salesforce : Force.com • IaaS: Organizations get computing power and storage capacity. Organizations in this case has complete control over the IT infrastructure including the hosting environment and the applications. However to manage these resources additional IT staff maybe needed. Thus windows Azure offers the IaaS. Platform as a Service (PaaS): To understand this cloud computing layer one needs to remember the traditional computing model where each application managed locally required hardware, an operating system, a database, middleware, Web servers, and other software. One also needs to remember the team of network, database, and system management experts that are needed to keep everything up and running. With cloud computing, these services are now provided remotely by cloud providers under this layer;

Software-as-a-Service (SaaS) : Applications are delivered through the medium of the Internet as a service Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management Free or paid via subscription, accessible from any computer, facilitates collaborative working Google, Microdoft, Zoho, pixlr, Jaycut, Aviary, Employease, NetSuite, Salesforce Microsoft Office 365 , Google Apps for Education collaboration suites, and the Salesforce.com Customer Relationship Management (CRM) system, Microsoft Dynamics CRM Online Offers a complete application functionality that ranges from productivity (e.g., office-type) applications to programs such as those for Customer Relationship Management (CRM) or enterprise-resource management.

Predictions for the Cloud The public cloud market is estimated to reach $191B by 2020, growing significantly from 2013’s market size of $58B Cloud applications are predicted to deliver the greatest proportion of the growth, reaching approximately $133B in revenue by 2020. Cloud platforms will contribute $44B in revenue and cloud business services, $14B by 2020 By 2018, 59% of the total cloud workloads will be Software-as-a-Service (SaaS) workloads, up from 41% in 2013 According to Gartner, Business Process as a Service (BPaaS) will reach $180 Mn from present $67 Mn. SaaS will grow from $176 million in 2013 to $572 million. IT spending on public cloud services will reach $1.4 billion $4.2 billion will be spent on cloud services in India, $1.8 billion of which will be spent on software as a service (SaaS).

Most Successful areas of Business Improvement as a result of cloud implementation Improve Business Performance Improve levels of Service Automation Reduce Costs Better integrated systems Introduce new features functions Enhance ability to interact with customers Rapidly deploy new solutions Replace legacy systems

Challenging Areas when adopting Cloud Security , Data Privacy, Cost Data loss and privacy Risks Risks of intellectual property theft High Cost of Implementation Legal and Regulatory compliance Integration with existing architecture Hard to integrate with in-house IT

Cloud Security Concerns Abate While the benefits of the cloud increase with experience, the challenges of cloud show a sharp decrease as organizations gain expertise with cloud Security remains the most-often cited challenge among Cloud Beginners (31 percent) but decreases to the fifth most cited (13 percent) among Cloud Focused organizations
