Cloud Computing

• About the Cloud

Cloud Computing

The “Cloud” is the default symbol of the internet in

diagrams.

The broader term of “Computing” encompasses:- Computation- Coordination logic- Storage

Cloud Computing is about moving computing from the single desktop pc/data centers to the internet.


Cloud Computing

• More formally…. – Fox et al. (Berkeley)

Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS), so we use that term. The datacenter hardware and software is what we will call a Cloud.

– Buyya et al.A Cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers.


Cloud Computing

So what ...?– Internet-based (the Internet is central..)– The entire stack (hw & sw) is leveraged to the internet

▪ HaaS Amazon S3▪ IaaS VMWare, Amazon EC2 ▪ PaaS Google AppEngine, Mosso, Aneka▪ SaaS SalesForce

– Computing becomes a real utility used by all the masses▪ researchers▪ end users▪ companies▪ service providers (web hosting)

– The economic aspect become more important (billing, pricing, QoS, SLA)

These are the two main differences from Grid Computing.

Are gadgets important?

As wireless technology gets better and cheaper, more and more different kinds of objects will connect directly to the cloud.

Flexibility: new needs can be solved quickly.Elasticity: temporary needs can be solved and you can “return” the infrastructure after the pick.New business: Smaller investmentTime-to-market:Faster Implementation

Synergies:Hardware investment can be spread Economy of scales:Hardware investment can be spread Alliance:Intel, HP e Yahoo

Hardware consolidation: Best use of money invested in hardwareHardware consolidation: Best use of money invested in hardware

Cloud – Cons …

Customer Supplier

Lack of cost advantage: Not achieving ROI before turn people sceptical with CC .Strategy: Large databases; critical data; old systems; systems that require specific hardwareMigration:Current enterprise apps can't be migrated conveniently.Management:Difficulty of managing cloud applications.

Safety:To manage customer data, the identification management must be solved Liability:…… Latency:…… Lack of Service levels agreements:Cloud providers still are not taking accountability for the platforms

Putative Risk: Legal, regulatory and business. Can our data be “elsewhere”?Putative Risk: Legal, regulatory and business. Can our data be “elsewhere”?

Pricing: How it is being charged. Migrate from boxes to services is a lesson to learn.Pricing: How it is being charged. Migrate from boxes to services is a lesson to learn.

Embracing the Cloud

• Benefits

– Infinite compute resource available on demand▪ Hardware virtualization

– Accessibility anytime and anywhere▪ Internet (web based) access

– Elimination of the upfront commitment of users▪ Reduced costs due to dynamic hardware provisioning

▪ Pay per use basis (and also other models)

▪ No need to plan for peak load in advance

– Easy management

▪ Software versioning and upgrading


Embracing the Cloud• Migration Risks

– Privacy▪ Who access your data?

– Security▪ How much you trust your provider?

▪ What about recovery, tracing, and data integrity?

– Political and legal issues▪ Who owns the data?

▪ Who uses your personal data?– Government

▪ Where is your data? – Amazon Availability Zones

Will it be fitting

for me?
