Cloud ComputingCloud 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

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

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
