Introduce to Public Cloud ServiceTaiwan ITQ


Agenda• About Public Cloud• Commercial Public Cloud service Introduction• Selected Labs:

Lab: Free Cloud StorageLab: Microsoft AZURE ServiceLab: HP Cloud


What is a Public Cloud?• A service provides the resources:

Applications

StorageCompute

Development platforms

Etc.

• Must be available to the public on the internet• Makes it easy for the public to access better web

browsing to meet their needs.• Are operated and managed at datacenters• Belonging to service providers and shared by multiple

customers


Benefits of ‘Public Cloud Computing’• Easy to use• Inexpensive to set up• Low cost• Hardware, application and bandwidth are managed by

the providers• Capable to be climbed up over and to meet the needs• No wasted resources

what you use, you pay for that

• Better ROI and faster time to market


Weakness of ‘Public Cloud Computing’• Less visibility and control• Security• Reliability• Data in the cloud


Delivery Models• IaaS (Infrastructure as a Service)

Shared infrastructure such as servers, storage and network are delivered as a service over the internet

Amazon Web Services, Rackspace Cloud, etc.

• PaaS (Platform as a Service)Application development framework offered as a service to developers for quick deployment of their code

Google App Engine, Heroku, Cloud Foundry, etc.

• SaaS (Software as a Service)Application software offered as a service using a multitenant model which can be consumed using web browsers.

Gmail, Salesforce, etc.


Trend Micro Survey Results• 43% of the respondents using a cloud service reported that they

have experienced a data security lapse/issue in the last 12 months.• 55% expressed concerns that shared storage is vulnerable without

encryption.• 49% of them said a guaranteed SLA will help them adopt public

clouds.• 93% of the respondents indicated that their organization is using at

least one cloud service when they were presented with a list of cloud providers.

However, 7% of these same respondents had previously indicated in the survey that their company had no plans to deploy cloud services —showing that this 7% did not realize that their company had already deployed cloud computing.

• 85% of those using a public cloud in production said they are encrypting the data stored in the cloud and keep a local copy synched to the cloud.


Cost Savings• Eliminates CAPEX(Capital Expenditure) and offers

reduced OPEX(Operating Expenditure)the maintenance and labor costs associated with managing the infrastructure is offloaded to a third-party provider.

• Ensures cost efficiency because of the pay-per-use models.

Service providers charge by the hour and this comes in handy when a company’s resource needs are for a temporary project or to meet a sudden spike in usage.

• Offers self-service provisioning, leading to lower costs and better agility

Human intervention in resource provisioning is minimized.


Business Flexibility• Provides massive scalability and an ability to re-

size compute resources. • Gives programmatic access to compute resources

through APIHelping applications scale automatically without any human intervention.

• Supplies robust infrastructure with better support staff, offering cost and talent advantages in an increasingly shrinking pool of expertise.


Security issue of public cloud• Multi-tenancy risks

unauthorized access of data by other tenants using the same hardware

resource contention

• Control and visibilityBusinesses have limited control and visibility because the vendor

is responsible for completely managing the infrastructure

• Security responsibility• Data and encryption• Data retention

When the data is moved or deleted by a service provider or customer,

there may be remaining data remnants

• Compliance requirementsDifferent countries have different regulatory requirements

on data privacy.


Public Cloud Use Cases• A video production company can use public clouds for video

rendering and pay for only the time they used the resources.• A business can tap into public clouds when they expect

unpredictable demand during a marketing promotion.• A pharmaceutical company can run their drug design

processes on public cloud, thereby, accelerating the time to market.

• ………• ………• More and more workloads can be moved to the public

clouds.


Additional question before adopt public cloud service Sufficient internet access bandwidth?

Business to Cloud Service Provider bandwidth Customer to Cloud Service Provider bandwidth

Will transform to other platform?


Security best practices• VM-level security• Multi-layered defense• Data and encryption• Patch management• Identity and access• Regulator compliance
