CloudLooks Foggy???

Well it isn’t… It simply means…


How does cloud computing look like?

Lets enter the cloud now…Saturday, April 8, 2023 3Vodafone Essar Ltd., Pune

Definitions by Analysts

Gartner

“A style of computing where massively scalable IT enabled capabilities aredelivered as a service to external customers using Internet technologies”

Forrester

“A form of standardized IT-based capability — such as Internet-based services,software, or IT infrastructure — offered by a service provider that is accessible viaInternet protocols from any computer, is always available and scales automatically toadjust to demand, is either pay-per-use or advertising-based, has Web- orprogrammatic-based control interfaces, and enables full customer self-service”


Its three delivery models…


IaaS It isInfrastructure as a Service


Includes infrastructures on which customers can deploy applications

Examples???

Examples

FlexiscaleAWS: EC2

AWS: Amazon Web Services


Services

- CPU- Server

s

SaaSIt is simply Software as a Service


Include complete applications that can be customized by customers and delivered over the Internet such as Gmail, salesforce.com, and enterprise applications delivered as a service

Examples any????Examples• CRM• Financial Planning• Human Resources• Word processingCommercial Services : Examples• Salesforce.com• Emailcloud


PaaSIt is Platform as a Service….


PaaS offerings are externally hosted services providing complete platforms to create, run, and operate applications, including development tools, administration and management tools

• Database• Scalability

Popular services

Example

Google App EngineAWS: S3

AWS: Amazon Web Services

S3 : Simple Storage Service


Key Benefits…


The “Cloud” = 10X Improvements

• Ease of Use• Scalability• Reliability• Cost Optimization


Ease of Use….

• Deploy infrastructure with a mouse or API– No cabling, screwdrivers, racking, buying– Infrastructure available on the fly– Do it yourself remotely from anywhere anytime


That was quite easy..

Scalability

• Ease of Use• Control your infrastructure with your app• Nothing to purchase and take delivery on• Instant


Reliability

• Good : enterprise grade hardware• Design for failures:

– Automatically spin up replacements– Use multiple clouds


Cost Optimization

• “Turn off the lights” = turn off servers you aren’t using– Eg: Turn off development and test environments

• Pay for only what you use• No need to buy in advance• Zero Capital Outlay


Deployments: Three Types

Virtual Private Cloud

Public Cloud• Public cloud services are characterized as being available to clients

from a third party service provider via the Internet• The term “public” does not always mean free, even though it can

be free or fairly inexpensive to use. • Public clouds provide an elastic, cost effective means to deploy

solutions • Public Cloud is implemented on thousands of servers running

across hundreds of data centres deployed across tens of locations around the world

• MNCs using public clouds: Eg: Hotmail, New York Times


Private Cloud

• A private cloud offers many benefits such as being elastic and service based

• The difference between a private cloud and a public cloud is that in a private cloud-based service, data and processes are managed within the organization without the restrictions of network bandwidth, security exposures and legal requirements that using public cloud services might entail

• In addition, it offers the provider and the user greater control of the cloud infrastructure, improving security and resiliency because user access and the networks used are restricted and designated


Hybrid Cloud• A hybrid cloud is a combination of a public and private cloud that

interoperates• In this model users typically outsource non business- critical

information and processing to the public cloud, while keeping business - critical services and data in their control


But does it work??

• Various providers let you create virtual servers– Set up an account, perhaps just with a credit card

• You create virtual servers ("virtualization")– Choose the OS and software each "instance" will have– It will run on a large server farm located somewhere– You can instantiate more on a few minutes' notice– You can shut down instances in a minute or so

• They send you a bill for what you use

YES!!!


But why go to Cloud????

• Lower cost of ownership• Reduce infrastructure management

responsibility• Allow for unexpected resource loads• Faster application rollout


Hey Cloud Computing has another side too…

There are some risks…..

Three RISKS to look at!

• Technical Risks- Cloud isolation failure- Ineffective capacity management or resource exhaustion- Malicious activities or attack due to multi-tenancy use of shared resources

• Legal Risks- No virtual boundaries or jurisdiction for data stored in the cloud- Lack of data protection by the Cloud Provider

• Organizational Risks- Loss of Governance due to direct control by Cloud Provider- Lock In with the Cloud Provider- Non compliance to customer defined policies and procedures

On the Gartner’s Hype cycle, 2009 it will take 2 to 5 years for adoption….

Cloud Computing NOW…

• Seems to be rapidly becoming a mainstream practice

• Numerous providers– Amazon EC2 imitators ...– Just about every major industry name

• IBM, Sun, Microsoft, ...

• Major buzz at industry meetings

Google Trends look like this….

Google Trends is a public web facility of Google Inc., about Google Search, that shows how often a particular search-term is entered relative to the total search-volume across various regions of the world. The horizontal axis of the main graph represents time and the vertical is how often a term is searched for relative to the total number of searches, globally.
