Cloud Computing Cloud Computing


You are not alone…

“Not sure, but I like these clouds better.” ~Guy sitting beside me on the plane, retired Economist

Ahmed: “What do you think this ad is trying to tell you?”


What the hell is cloud computing?

Oracle CEO Larry Ellison in an analysts’ briefing on

September 2008:

“Orange is the new pink…”

“I don’t understand what we would do differently in the light of

cloud computing, other than marketing.”

Oracle Cloud Hype

Cloud is at the peak of the hype curve


Virtualization

The Foundation for Cloud


Virtualization

Virtualization and clustering widely adopted

in most organizations

Provisioning a single physical server took

months

Physical resources were often underutilized

Virtualization helped:

Reduce provisioning time

Maximize physical resources

Introduce concepts such as cloning and snapshots


Setting up a VM with VMware Server

1. Request and approval to setup new VM ~2880 minutes

2. Copy VM image to new folder ~20 minutes

3. Configure VM ~10 minutes

4. Recreate network adapter ~10 minutes

5. Startup VM through console ~15 minutes

6. Reconfigure networking and NATing ~15 minutes

7. Configure miscellaneous scripts ~20 minutes

8. Send completion email ~240 minutes


Scaling out using VMware Server

1. Setup clone of existing VM ~ 3175 minutes (~90 minutes)

2. Reconfigure software on 2nd node ~180 minutes

3. Startup software on 2nd node ~20 minutes

4. Configure cluster ~140 minutes

5. Verification, first round ~90 minutes

6. Add 2nd node to load balancer ~60 minutes

7. Verification, second round ~250 minutes


Virtualization & Clustering are Foundations for Cloud

• Both server virtualization and clustering are key technologies for cloud • Virtualization provides resource pooling • Clustering provides elastic scalability

Server Virtualization (Resource Pooling)

Clustering (Scalability)

Make one physical resource look like many Make many physical resource look like one


Cloud Concepts

\ NIST Definition of Cloud Computing

Cloud computing is 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.

This cloud model promotes availability and is composed of:

3 Service Models

• SaaS • PaaS • IaaS

4 Deployment Models

• Public Cloud • Private Cloud • Community Cloud • Hybrid Cloud

5 Essential Characteristics

• Broad network access • Resource pooling • Rapid elasticity • On-demand self-service • Measured service

http://csrc.nist.gov/groups/SNS/cloud-computing/cloud-def-v15.doc


Cloud != Virtualization

“Cloud” is not “virtualization”, but relies on virtualization and clustering

concepts and technologies

Cloud is:

On-demand resources

Rapidly provisioned (i.e., self-service provisioning)

Minimal management

Elastic (i.e., workload management)

Measured service (e.g., metering and chargeback)

Summary


The Good

Public clouds generally have tremendous cost savings

If your application can support elasticity, then this is huge

Quick provisioning is a huge benefit

By reducing management and administration of core platforms

and/or environments, infrastructure team can focus their efforts

elsewhere beyond the everyday administration tasks

Hybrid clouds are an awesome concept for disaster recovery, setting

up load testing environments, etc.

Pay for what you use only


The Bad

The majority of Oracle applications (and in fact, most non-Oracle

applications) don’t support elasticity

Vendor lock-in is a concern

DR in a hybrid cloud model sounds good in theory, but needs to first

be proven out due to the complexities involved

Private clouds are just glorified virtual servers and rely on having

idle hardware lying around to afford elasticity

Security is a perceived concern in the public cloud, a lot better now

How much do you trust your public cloud provider?


Summary & Recap

Hype/disillusionment are over, cloud focus is now on productivity

Virtualization and clustering are enablers for the cloud

Cloud concepts: Characteristics: self-service provisioning, minimal management, elasticity, measured service

Deployment models: Public, Private, Hybrid

Service Models: IaaS, PaaS, SaaS

Consumers of cloud services: IaaS: IT admins

PaaS: Developers

SaaS: Business users

Next steps for deployment models: Virtualized data centers will evolve into private clouds

With maturity, hybrid clouds can be useful for DR environments, scaling out, load testing environments
