Before cloud computing…

Common business situations

What is Cloud Computing?

•Infrastructure, applications, and business processes can be delivered to you as a service, over the Internet rather than a local server

Service models

Cloud layers:•Software as a Service (SaaS)•Platform as a Service (PaaS)

•Infrastructure as a Service(IaaS)

SaaS

•Delivers one application to many users regardless of location

•Allows architecture, pricing, partnering, and management characteristics to be managed from one central location

Visual of SaaS

Tips to get you started with SaaS•Compare the up-front cost savings to

long-term subscription usage•Look for the ability to customize or

configure the application for your environment

•Make sure a SaaS solution has all the features you want

•Don’t focus solely on costs•Make sure you own your data

Companies that use SaaS

PaaS

•Develop new applications that do not depend on a specific platform to run

•Can support integration with legacy applications

•Can create multi-tenet applications

•Best for collaboration

Tips to get you started…

•Look for providers that help you develop more custom web apps faster

•You can lease capacity

•Compare how well vendor tools enable portability across clouds

Companies that use PaaS

IaaS

•Rent a data center capacity as needed

•Provides compute power, memory, and storage, typically priced per hour based on resource consumption

•No need to install new equipment or to wait for the hardware procurement process

Tips to get you started…• Weigh the impact to your IT organization before

adopting IaaS

• Create a strong internal team to manage your security and compliance requirements with a chosen cloud provider

• Make sure you have a thorough understanding of how your current system works

• Plan an exit strategy

Companies that use IaaS

Challenges with the cloud

•Security and Privacy

•Service Quality Case Study: Amazon Web Services

•Performance

•Integration

HBR article suggestions

•Ask vendors where and how the data would be stored

•Ask how the vendors would guarantee the data's availability

•Bring in specialists who are well versed in the technical issues of cloud platforms to closely read the service-level agreements offered by vendors

HBR article suggestions

•Consider cloud-based processes along two dimensions: operational dependence and risk tolerance

Myths about the Cloud

•Going to the cloud is “green”

•Don’t have to worry about IT anymore

•Will never suffer downtime

•Save money

Choosing the right cloud for you

•Risk tolerance

•Payment options

•Public or Private?

When it may not be right for the cloud

•Sensitive data is best kept local. Sure you can use encryption, but with any good security paradigm you make it more difficult for hackers, bots and yourself

•If your applications require specific hardware components, or your application requires complete access to the server, cloud computing may not be a good fit

•Mission critical applications are not good candidates for cloud computing

Using the cloud now?

•Amazon cloud player•Google Drive•Prezi•Slide Rocket• iCloud•SharePoint
