- 25. Для возможности метизации была реализована система учета трафика клиентов по нескольким параметрам: Количество закачаных/ скачаных байт или экземпляров. Количество байт и экземпляров в онлайн хранилище пользователя. Количество обработанных ссылок для скачивания. Время действия тарифного предложения в днях. Тарифные предложения настраиваются в виде лимитов на вышеперечисленные счетчики. При превышении лимита одного из счетчиков, у пользователя перестает работать часть функционала сервиса. Например, у пользователя установлен лимит на скачивание, загрузку файлов и на используемый объем хранилища: При превышении лимита на загрузки файлов – функционал загрузки файлов становится недоступным для нользователя, но он может продолжать кешировать книги в телефон. При перелимите объема хранилища – у пользователя пропадает функционал наполнения своей библиотеки. Windows® Azure™ Platform
- 26. В качестве базовой единицы для расчѐта была посчитана цена одного мегабайта хранилища для пользователя исходя из следующих соображений: - Для комфортного использования сервиса одна веб роль и воркер роль должны обслуживать 200 клиентов. - Один клиент тратит 1 ГБ трафика в месяц и генерирует 100 тыс. транзакций. - Комиссия платежной системы и уплата налогов. - Полученная сумма умножается на 2.

Разбиение историй на задачи • User Story это нечто, что можно продемонстрировать, что представляет ценность для product owner’а, а задачи либо нельзя продемонстрировать, либо они не представляют ценности для product owner’a. Абсолютно понятные истории разбивать на задачи заранее так же легко, как и по мере их выполнения. Такая разбивка часто позволяет выявить дополнительную работу, которая увеличивает оценку, чем обеспечивается более реалистичный план на спринт. Такая предварительная разбивка заметно увеличивает эффективность ежедневного Scrum’а. Даже неточная разбивка, которая будет изменяться по ходу работ, всѐ равно даѐт все перечисленные выше выгоды. 67

- Windows Azure: operating system as an online serviceSQL Azure: relational cloud database solutionWindows Azure platform AppFabric: cloud middleware platformWindows Azure Marketplace DataMarket: information marketplace for data and web services Windows Azure™ is a cloud services operating system that serves as the development, service hosting and service management environment for the Windows Azure platform. Windows Azure provides developers with on-demand compute and storage to host, scale, and manage web applications on the internet through Microsoft® datacenters.Windows Azure AppFabricis a comprehensive middleware platform that enables building applications in the cloud or on-premises. This includes applications running on Windows Azure, Windows Server and a number of other platforms including Java, Ruby, PHP and others.Windows Azure Marketplace DataMarketis a new service allowing developers and information workers to easily discover, purchase, and manage premium data subscriptions in the Windows Azure platform.SQL Azure™ Database is a cloud-based relational database service built on SQL Server® technologies. It provides a highly available, scalable, multi-tenant database service hosted by Microsoft in the cloud.
- Slide ObjectivesUnderstand Roles in generalUnderstand Web and Worker Roles at a high levelSpeaker NotesWindows Azure currently supports the following two types of roles:Web role: A web role is a role that is customized for web application programming as supported by IIS 7 and ASP.NET.Worker role: A worker role is a role that is useful for generalized development, and may perform background processing for a web role. A service must include at least one role of either type, but may consist of any number of web roles or worker roles. A worker role is started by a call to a well know managed code interface RoleEntryPoint. A worker role must extend this class and override the Start() methodA web role is a worker role with the addition of IIS being installed. i.e. it has all the features of and can do everything a worker role can do as wellNoteshttp://msdn.microsoft.com/en-us/library/dd179341.aspx#Subheading1
- Slide ObjectivesIntroduction to Windows Azure StorageHigh availability via ReplicasStorage account introductionDiscussion of REST API and the managed code wrapperSpeaker NotesThe design point is for the cloud is availability of storage, there are 3 replicas of data, and we implement guaranteed consistency. In the future there will be some transaction support and this is why we use guaranteed consistency.Blobs, tables, and queues hosted in the cloud, close to your computation Authenticated access and triple replication to help keep your data safe Easy access to data with simple REST interfaces, available remotely and from the data centerAccess is via a storage account – you can have multiple storage accounts per live id.Although the native API is REST web service, there is a .NET storage client in the SDK that. This makes working with storage much easier from .NETThere are 4 types of storageTables = Key value storeQueues = a simple queuing mechanismBlobs = Binary file storage in the cloudDrives = A mechanism that allows a VHD in a blob to be mounted as an NTFS drive into a Compute roleNotes
- Connect? Virtual Network???
- Slide ObjectivesAffirm that SQL Azure is just a TDS server. Existing SQL Server consumers can connect to itSpeaker NotesConnecting to SQL Azure is simply a case of changing the connection string.The SQL Azure fabric ensures 3 transitionally consistent replicas of your data You will connect to a SQL Azure TDS gateway, this appears to be a SQL Server but will actually route your requests through to one of the three replicas stored in the DCAvoid injection attacks by using the SqlConnectionStringBuilder class. It is available from the .NET Framework to simplify creating the connection string. For more information, see Connection String Builders (ADO.NET).Carefully protect your connection string. A connection string presents a potential vulnerability if it is not secured. For more information, see Protecting Connection Information (ADO.NET).In order to completely secure your connection, especially when connecting to SQL Azure over the Internet, insure that the ADO.NET Encrypt and TrustServerCertificate connection parameters are set.For general considerations about connecting to databases in SQL Azure, see Guidelines for Connecting to SQL Azure Database.More on security of SQL Azure in Day 3Noteshttp://msdn.microsoft.com/en-us/library/ee336243.aspx
- Slide objectives:Provide a visual representation of the Service Bus, and reinforce it’s purpose and value.Speaking points:The way I want you to think about the service bus is that it’s a communication fabric in the cloud; a connectivity and messaging fabric in the cloud.Take disconnected application and components that normally wouldn’t be able to talk to each other, and interconnect themTake your existing on-premises applications and services and extend them so that you can reach them through the cloud.Here in the picture you see App 1 – it could be anything, a service, and client application, etc. – and you want to connect it to the Service Bus to extend its reach.Then you have App 2 – it could also be a client application or service – and you want to connect it up to the Service Bus so that the two can start communicating.App 2 could belong to another company or organization – it doesn’t matter. So long as they have access to the Internet you can make this happen.NotesConnect distributed components to build composite applicationsExchange messages between loosely coupled applications without altering the network topologyNetwork Send/Receive from any Internet connected deviceTraverse NAT/FirewallMessage buffering for loosely connected applicationsFacilitate direct P2P ConnectionSpeaking points: Call out the following key pointsConnectivity through service bus relay in the cloudOutbound connectivity makes traversal of NAT/Firewall devices much easierDirect connection mechanism uses NAT probing- similar technology to that found in IM and VOIP clientsVariety of scenarios supportedSimple content and messages all the way through to full TCP/IP port forwardingNotes: Much in the same way that SQL Services is about extending SQL Server to the cloud, we are also extending key .NET capabilities to the cloud as services.We call these .NET Services. Some of you maybe familiar with previous codenames such as BizTalk Services.These services are really key components you would need for building distributed, connected applications. When we talk about connecting to your existing on-premises applications and enabling the composition of hybrid (Cloud + on-premises) applications – that is where .NET Services really comes in.There are currently two .NET Services: the Service Bus & the Access Control ServiceService Bus:The Service Bus is designed to provide a general purpose application bus, available on the internet at internet scale. You can really thin of the Service Bus as being similar to an Enterprise Service Bus that many enterprise organizations have today. However, we believe that when providing a Service Bus as a programmable service on the internet, there are a wider range of scenarios for many more types of organizations.Fundamentally, the .NET Service Bus is about connecting applications across network and application boundaries and making key message exchange patterns such as publish and subscribe messaging very simple.Access Control:The Access Control service is designed to provide rules-driven, claims-based access control for applications. Essentially, this allows you to define authorization rules for your applications using the claims-based approach that we are adopting within many Microsoft products and technologies and that is becoming adopted in the industry.Windows Azure has the .NET Framework built into it so thatyou can use those services within your application.But just like your application must be designed to scale out, the services that we have built into Windows over time in .NET also need to be designed and built in a way that can scale out naturally. We want to create services for you, and that's the purpose of .NET services, creating a pool of resources available to you to take advantage of and do things within your application very simply. So we're including a built-in, scale-out implementation of a service bus. The service bus lets you connect your on-premises systems securely into the cloud, into the Azure environment, while allowing your data and your information to traverse firewalls, solving a problem that is a bane of many application developments. Primary patterns today:Service remotingExpose an inside-the-firewall WCF service to clients in other organizations and in the cloud EventingAllow one-to-many event notification via the cloudProtocol tunnelingInterconnect applications that don’t communicate via Web servicesAll of these patterns are able to leverage secure communication and benefit from NAT and firewall traversal that the Service Bus brings.Service RemotingExtend web services to the cloudBroad support for WS-* protocolsEventingEfficient pub/sub style messagingHigh performance one way broadcastSupports disconnected modes through the use of short-lived message buffersTunnelingTunnel TCP sockets or raw named pipes right over the InternetCan tunnel complex protocols over simple protocols (i.e. tunnel SQL Server named pipes when only outbound HTTP is available)

- Slide ObjectivesProvide overview and detail on pricingDiscuss localization of pricingSpeaker NotesWindows Azure is charged per compute hour.Pricing is localized for global marketsDifferent VM sizes have a different number of CPUs and therefore are a multiple the single CPU rateCompute time, measured in service hours: Windows Azure compute hours are charged only for when your application is deployed. Remove the compute instances that are not being used to minimize compute hour billing. Partial compute hours are billed as full hours.Storage, measured in GB: Storage is metered in units of average daily amount of data stored (in GB) over a monthly period. Data transfers measured in GB (transmissions to and from the Windows Azure datacenter).Data transfers within a sub region are free. Transactions, measured as application requests to the REST serviceNoteshttp://www.microsoft.com/windowsazure/pricing/-----Slide ObjectiveUnderstand SQL Azure pricing. Understand the specifics of the no-prorated modelSpeaker notesSQL Azure is priced on a per database per month basisNoteshttp://www.microsoft.com/windowsazure/pricing/#sql ----Slide ObjectiveUnderstand the AppFabric Pricing modelSlide NotesAppFabric Service Bus is based on a per connection modelAppFabric Access control is based on a per transaction modelAppFabric Service Bus connections can be provisioned individually on a “pay-as-you-go” basis or in a pack of 5, 25, 100 or 500 connections. For individually provisioned connections, you will be charged based on the maximum number of connections you use for each day. For connection packs, you will be charged daily for a pro rata amount of the connections in that pack (i.e., the number of connections in the pack divided by the number of days in the month). You can only update the connections you provision as a pack once every seven days. You can modify the number of connections you provision individually at any time.For AppFabric Access Control transactions, customers will be charged the actual number of transactions utilized for the billing period (i.e., not in discrete blocks of 100,000 transactions), plus data transfers in or out.Always pay the data traffic costs that apply to your appNoteshttp://blogs.msdn.com/b/netservices/archive/2010/01/04/announcing-windows-azure-platform-commercial-offer-availability-and-updated-appfabric-pricing.aspx http://www.microsoft.com/windowsazure/pricing/
- For WAPU: Now that we know how Windows Azure apps are built—from instances—we can sensibly talk about some of the most interesting cloud workload patterns. These are all made possible by adding and removing instances to a running application.Original Slide Notes---------------------------------------------------------------------------------------------------------------------------------Examples:3M needed a way to have its designers the ability to invoke complex algorithms that analyze 30 years worth of data, Riskmetrics, Lokad that does forecasting/modeling for retailers and e-commerce companiesKBB unpredicable burstingGrowing fast – any SaaS based solution that has no idea how much adoption will be (three Melons)Predicatable bursting – OCC Match that needed to be able to run job matching during certain times of day.
- Key Points:Large application suites benefit from the Windows Azure environment because of the removal of capital infrastructure and many other opportunities.As the suite of migrated applications grows, EA pricing can be used for the suite’s cumulative resource needs to lower customer costs.Speaker Notes: This example is of a connected business suite applications which is the subject area of the IT Portfolio Assessment. This suite comprises of applications for email and mailbox storing, calendar and scheduling tools, video communication clients, online word processors, online presentation-creation tools, data repository and other business intelligence tools. The combined functionality helps the customer organization to communicate and operate on a global scale. Here we are starting off with 50 applications being migrated after an assessment was done. The application variables and pricing shown in the middle reflect an average application among a suite of different applications. Each individual application would likely have different needs and so may require increased capacity or speed in the compute instances or another variable. This suite of applications will continue to expand with new applications as the business grows and development in the cloud rolls on. The phased migration to the 100 application mark is also priced to show how this evolution would change over time and the price savings changing. The actual price would vary depending on the migration approach, seasonality, business drivers and other influencers.An enormous advantage of having these services hosted in the cloud is the removal of capital expenditures such as provisioning servers or maintaining and supporting a data warehouse for equipment storage and upkeep. Being able to streamline application operations is one of the key values of Microsoft’s Window Azure Platform. It provides organizations with the ability to move away from the physical data center environment and reduce the number of people that are required to maintain an IT infrastructure. This cost savings provides businesses with more resources that can go to achieve more strategic business objectives. Additionally, the transparency of the Windows Azure Platform makes it possible for customers to have a clear understanding of the cost and benefit of each application being used in the suite. This can help determine the value of an application and whether it may need to be redesigned to be more cost effective in the cloud. Through Windows Azure, Microsoft has created a support system that organizations can use to not only interface with the customer, but protect their data and free up resources on premises. Microsoft has provided customers with the ability to deploy enterprise level technologies at a fraction of the cost. In this example, the average application uses a enterprise agreement pricing levels and discounts. Enterprise Account pricing brings in a 20% discount on the normal compute and database commitment savings and 10% discount for other Windows Azure Platform services. Additionally, since this customer fits into tier 1 or level A thresholds, it will get an additional discount of 3.71%. The remaining excess Windows Azure Storage and outgoing data transfer is covered by consumption pricing. This comes to a savings of 56% for the 50 application level and then 60% for the 100 application level compared to a hosted solution, when calculated by the TCO tool.
- Key point: There are multiple methods for monetizing cloud offerings….and they are not all mutually exclusive. Many cloud providers successfully combine several methods to arrive at a hybrid pricing model. Details for each pricing model are included belowFree models:Providing a basic level of service for free and then offering premium upgrades. There is much to be said in favor of incorporating this method into your pricing model since it significantly reduces any barriers customers may have in trying out your software. Once they have started to derive business value from it, they will quickly outgrow the limited number of features available to them and want to upgrade. Your challenge here of course is to package your features and functions in such a way as to increase the number of customers who are upgrading.Ad Based Revenue is a valid pricing method, though a tough one to successfully implement. Having said this, Google and Facebook have both generated significant revenues from advertising while providing their services free of charge for users. Other companies can also make this model work for them.Related Services charged – in this model the application is free but you may have to pay for some related service or virtual goods. Most commonly this is leveraged in free games where you can do micro transactions and in consumerwebsitesPer UnitPer Meter - this has applicability only in certain situations. It is good, for example for file sharing or backup applications. When it is applicable, it is often used in combination with other methods such as per user pricing. The growth goal in this scenario is to increase storage per customer.Per transaction pricing is also a common pricing method, but not applicable to every application where it may be hard to carve out discrete transaction units. The growth goal here, of course, is to increase the number of transactions per customer.Per User pricing is one of the most common pricing mechanisms. This may include number of seats or named users. Once again packaging your offering in such a way as to make premium upgrades available will help to ensure that you are providing a low end, easy point of entry for your customers and then quickly encouraging them to upgrade in order to have access to an expanded set of functions and features and/or additional users, thereby increasing your average revenue per customer.Payment typesA monthly subscription is one of the most common payment mechanisms though lack of robust billing systems means that this is often billed annually in commercial sales. Consumer sales however require the billing systems to be in place even before the service is offered.Revenue Share many services which are sold via a reseller require the ISV to take a cut of the revenues and share the rest. The share is most often higher for whoever owns the brand and customer relationship.Perpetual License Fee this is seen most often in companies that offer on-premise software and have not yet fully transitioned to the cloud business model.
