Cloudwork

This document discusses the benefits and considerations of using cloud computing. Some key benefits include flexibility, speed, pay-as-you-go costs, and removing the need for specialized resources. However, there are also security, regulation, and infrastructure dependency concerns. It emphasizes that a hybrid cloud model combining internal and external systems provides the best solution. Integration between different cloud resources and internal systems requires tools like a cloud broker and XML gateway. Case studies demonstrate how the cloud can enable scaling, content distribution, and cost-effective marketing campaigns.

Exploring the clouds for youA brief description of how cloudwork can help your company online
Reasons to use the cloudFlexibilitySpeed / PerformancePrice / CostsStandardized SLA Removes need for specialized resourcesStanding on the shoulders of giantsPay as you go, no capexConsumer model
Reasons NOT to use the cloudRegulationInfrastructure dependenciesSecurity concernsOrganization Standardized SLA Fixed Pricing ParadigmFear Uncertainty Doubt
Standard SLAService Level Agreements tend to be a complex game between various parties.Hard to enforce without explicit knowledge and fluid since it is only for one case.Standard SLA is the same for all customers, they do not cover everything but are clear for everybody. Gaps need to be filled, which is possible on a ‘lower’ level in the organization.Setup is cheaper but enhances flexibility of the organization since there are more options.Requirement is that the cloud solution is fairly portable which allows moving instead of renegotiations.
It is not a choiceIt will always be a hybrid solution between internal systems and multiple online systems. Managed as the hybrid cloud.There is a need for integration on two levels:ProcessingCloud computing systems like Nimbula allow for running the required systems internally while pushing everything dynamic into the cloud.DataIntegrate systems on data level allowing you to let the components internally and in the cloud to work together. XMLGateways can help you do that.
Hybrid CloudHybrid clouds consists of:Public cloudShared resources using shared systemsPrivate cloudShared resources using dedicated systemsStatic IT elementsDedicated resources using dedicated systemsPublic is the most elastic, static obviously isn’t.
GlueGlue is needed to patch the parts together.We have specific tools for thatHybrid Cloud (Nimbula)Binds processing resources between all types of infrastructure systems into one hybrid cloud.Cloud Broker (Vordel)Ensures the application data infrastructure to functionally bind the resources together.
Unlocks your internal resources for the InternetAdds rock-solid Triple A securityAvailable as virtual machine or as a hardened appliance for bigger infrastructuresCan replace complex application server middlewareXMLGateway
Scaling static elementsThree methods of scaling static elements:Caching and storing generic data
Intermediate data storage
Asynchronous infrastructureA combination of all methods is most efficient but there is still a maximum because elasticity is absent. This is why shortages need to be handled gracefully:Throttling
Load distributionCloud BrokerConnects your organization with the Cloud by extending a XMLGatewaywith a Cloud Broker for integration with online resources. The gateway allows for secure and fast interaction.Can be used to integrate internal and external systems like Salesforce with SAPAlso useful to include cloud resources in a public API or to cloudify resources for offloading internal systems.
Use case : Customer Selfservice
Public API using XMLGatewayPubli
Content Distribution via Cloud95% of all data sent online is identical (static).This data can be pre-delivered at the ‘edge’ location of the Internet close to the users.Due to massive distribution the availability of this 95% drasticaly improves.Can be optimized to use the browser caching as well:Lower bandwidth used.Faster loading time.Better user experience.
Cloud case 2: Marketing SupportSeveral small campaigns are started and images are invoked for $80/monthA campaign should not be punished for their success. Usage based pricing makes calculation comparable to marketing on other channels.Several images run on EC2, but also Google AppEngine and other platforms are tested.The ability to execute directly on several online platforms cheaply and quick has given an impulse to online campaigns.
Example: Animoto and AWSAmazon EC2 easily scaled up and down to handle additional trafficPeak of 5000 instancesNumber of EC2 InstancesLaunch of Facebook modification.Steady state of ~40 instances4/12/20084/14/20084/15/20084/16/20084/18/20084/19/20084/20/20084/17/20084/13/2008
SuperscalingGet rid of complex batches because of limited hardwareOn demand capacity for:Business IntelligenceBilling processesAnalysisBatches distributed over weeks, done at night can be performed in minutes using a cluster of 1000(!) machines for about $10.This changes a lot in organizations since we can eliminate the waiting and decimate the costs of reporting. First steps to the real-time enterprise.

Cloud Awareness (1)Alignment of technology and work with what is already available in the cloud.Help customers to use the faster and flexible environment to get business advantage.Involve new online channels outside the realm of marketing.Online availability is part of the user experience of a company regardless if it involves a customer, employee or partner.
Cloud Awareness (2)Create businessmodels using crowdsourcing of experts to optimize performanceDrive development faster through continuousbuild, integration, test and deployment methods.Use public APIs to open up internal resources for specialists online.
