concepts iaas - paas - saas *** private cloud the organization deploy their their own cloud in there infrastructure, they buy virtualization capable services and virtualized their services and client pcs wh ich they access by using thin clients (remoto) saves a lot of infrastructe investimento. it's an In house cloud the security in total control stil liees in the hand of t he organization it's suitale for large onetworks *** Public Cloud this is where the orgnization opt to use the service provided by a third part, e xmple (amazon, microsoft azoon) and outsource their infrastructure. the control an security llies with the service provider. *** Community cloud lets say there're 4 organizations with almost the same computing need. if they do in house infrastructure setting each will have to develope their on n etwork and maintain it, which is a costly proposition instead thei get together and pull their monetory resources and build the cloud which only these 4 organizatios can utilize, it's not open to the public. this is a community of people pulling their resource to develop their on cloud. since there are multiple oganization using the same cloud it cannot be called a private cloud and since its not open to the public its not a public cloud either .

*** Service models that can be used over the cloud Sotware as a service (Saas) this is where the software is locate else where at a remote location and can be access though the internet using a browser. the service here provided is that the software hands the app name...ex.facebook, email Platform as a Service (PaaS) here a designed platform like .NET is rented for development purposes ex. you want to develop an aplication based on .NET framwork, then you buy a com puter, buy the .NET framework for development and create a enviroment for testng the app.. this is a lot of money... instead using your eisting computer or a th in client you proch microsoft azoon nd rent a virtual pC for the developement, r ent the .net framework and rent the test environment. once you finished with appl you can just pay the rent for tulizin those services and dicard them when done. these saves you the investiments on infrastructure and you only pay rent for usa ge. This also keeps the cost f your appl down Infrastructure as a Serviice (IaaS) this is where you rent computation and or storage space as a meet of service. t hese concept is based on utility computing each is been around for years. Howeve r utilty conputing never took off due to lack of virtualizaion which made this m odule economic inviable. the cost in utility of usage U$1 per 1 hou of usage. this service is similar to a pipe gas connection or a eletricity connection. *** Essencial characteristics of a cloud

== On demand self service this is scalable model, which means you can upgrade or downgrade your infrastruc ture as needed yourself by logging into your account for the service provided. s o if you feel there's going to be a spike in the near feature in a workload then you can just deploy a few virtual machines in your infrastructure to manage the spike and when the workload decreases then you can discard those virtual machin es you only pay for the usage of those machines. - rapidity, elasticity - the updating and downgrading in this situaton takes onl y minutes as existing templates are used. you dont have to wait a long perid of time for the machines to be destroid or d eployed. - resource pooling - all your hardware resource are pull together to form a stro ng reliable virtual environment to meet your needs - measured services - the services provided are charged to you only for your us age and not on a montly or a daily rental, you use it just 5 hours today and 3 h ours tomorrow you be charged only 8 hours of utilization. **** common characteristics - massive scale - clouds are generaly deployed on a massive scale there's where the infrastructure is huge, these results on a lots of saving in infrastructure investments - homogenity - the infrastructure is composed of smiliar or identical part or el ements. - virtualization - they key component of cloud computing. take out the vitualiza tion from the cloud and you're looking at the great computing model..ou seja nao eh nada - low cost software - in a cloud the emphasis is on using open source software t o keep costs low also licensing is entirely difente in cloud to virtual machines resilient computing -

======================================================================= Both cloud computing and grid computing are scalable. Cloud computing is made up of thin clients, grid computing, and utility computing. Cloud computing may be more environmentally friendly than grid computing. Grid computing is NOT suited for storing objects as small as 1 byte. =================================================================== All of the following are security risks associated with cloud computing, EXCEPT: a)false positives b)regulatory compliance c)data location d)data recovery False positives are NOT security risks associated with cloud computing. False po sitive is a risk management term that refers to when you mistakenly identify som ething as a security vulnerability. Often spam filters have false positives when a legitimate e-mail message is tagged as spam. Cloud computing, also referred to as a provider cloud, facilitates computing for heavily utilized systems and networks. The following security risks should be e xamined when considering using cloud computing: -Regulatory compliance - Consider how the cloud provider will comply with the fe deral, state, and local regulations that apply to your organization. -Data location - Consider where your data will be physically stored. -Data recovery - Consider what happens to your data is case of disaster. -Investigate support - Consider how security breaches will be investigated. -Long-term viability - Consider if the cloud provider would ever close or sell t o a larger entity. -Data segregation - Consider that your organization's data can reside in the sam e physical space as a competitor. -Privileged user access - Consider who from the provider who have access to your data. ====================================================================== Your organization has decided to implement cloud computing and has set up Platfo rm as a Service (PaaS) with a cloud provider. What is the main focus of this typ e of cloud deployment? application access management virtual machine management data protection access control The main focus of a Platform as a Service (PaaS) cloud computing deployment is d ata protection. The main focus of a Software as a Service (SaaS) cloud computing deployment is a pplication access management. The main focus of an Integration as a Service (IaaS) cloud computing deployment is virtual machine management. None of the cloud computing deployments has access control as a main focus.
