Slide Objectives:Explain how Hosting is done.Speaking Points:Hosting is done by hosting providers.Hosting is done via FTP using file zilla client.Individual or organization admistrator should upload the files regularly.He/she should report to site hosting provider to their Netwrk admin Database adminHectic Process in reporting the addition of features updating,scaling
As explained above the process involved in maintenance of hosting of website and their Maintaince is hectic process.Lets see what are the problems involved in this reliability (systemic def.) is the ability of a person or system to perform and maintain its functions in routine circumstances, as well as hostile or unexpected circumstances.scalability is the ability of a system, network, or process, to handle growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth
Slide Objectives:Explain how Microsoft thinks of the cloudSpeaker Notes:There are numerous terms and definitions floating around in the industry for “the cloud”, “cloud computing”, “cloud services”, etc.Microsoft thinks of the cloud as simply an approach to computing that enables applications to be delivered at scale for a variety of workloads and client devices.The cloud can help deliver IT as a standardized service…freeing you up to focus on your business
Slide Objectives:Explain the three established terms in the industry for cloud servicesSpeaker Notes:There is a lot of talk in the industry about different terms like Platform as a Service, Infrastructure as a Service, and Software as a Service.Since PDC08 when we first announced the Windows Azure our focus has been on delivering a platform as a service offering where you can build applications. Where the platform abstracts you from the complexities of building and running applications. We fundamentally believe that the future path forward for development is by providing a platform. In fact, as you’ll see in a few minutes, we believe that there are a number of new capabilities that should be delivered as services to the platform.Notes:There is a lot of confusion in the industry when it comes to the cloud. It’s important that you understand both what is happening in the industry and how we think about the cloud. This is the most commonly used taxonomy for differentiating between types of cloud services.The industry has defined three categories of services:IaaS – a set of infrastructure level capabilities such as an operating system, network connectivity, etc. that are delivered as pay for use services and can be used to host applications. PaaS – higher level sets of functionality that are delivered as consumable services for developers who are building applications. PaaS is about abstracting developers from the underlying infrastructure to enable applications to quickly be composed. SaaS – applications that are delivered using a service delivery model where organizations can simply consume and use the application. Typically an organization would pay for the use of the application or the application could be monetized through ad revenue. It is important to note that these 3 types of services may exist independently of one another or combined with one another. SaaS offerings needn’t be developed upon PaaS offerings although solutions built on PaaS offerings are often delivered as SaaS. PaaS offerings also needn’t expose IaaS and there’s more to PaaS than just running platforms on IaaS.
Slide Objectives:Explain the differences and relationship between IaaS, PaaS, and SaaS in more detail.Speaker Notes:Here’s another way to look at the cloud services taxonomy and how this taxonomy maps to the components in an IT infrastructure. Packaged SoftwareWith packaged software a customer would be responsible for managing the entire stack – ranging from the network connectivity to the applications. IaaSWith Infrastructure as a Service, the lower levels of the stack are managed by a vendor. Some of these components can be provided by traditional hosters – in fact most of them have moved to having a virtualized offering. Very few actually provide an OSThe customer is still responsible for managing the OS through the Applications. For the developer, an obvious benefit with IaaS is that it frees the developer from many concerns when provisioning physical or virtual machines. This was one of the earliest and primary use cases for Amazon Web Services Elastic Cloud Compute (EC2). Developers were able to readily provision virtual machines (AMIs) on EC2, develop and test solutions and, often, run the results ‘in production’. The only requirement was a credit card to pay for the services.PaaSWith Platform as a Service, everything from the network connectivity through the runtime is provided and managed by the platform vendor. The Windows Azure best fits in this category today. In fact because we don’t provide access to the underlying virtualization or operating system today, we’re often referred to as not providing IaaS.PaaS offerings further reduce the developer burden by additionally supporting the platform runtime and related application services. With PaaS, the developer can, almost immediately, begin creating the business logic for an application. Potentially, the increases in productivity are considerable and, because the hardware and operational aspects of the cloud platform are also managed by the cloud platform provider, applications can quickly be taken from an idea to reality very quickly.SaaSFinally, with SaaS, a vendor provides the application and abstracts you from all of the underlying components.
Speaker Notes:Windows Azure services are backed by a monthly SLAGiving you the confidence to deliver applications and solutions to your customers
Speaker Notes:With Windows Azure you pay only for what you useEnabling you to avoid up front cost and scale as your business grows.
Speaker Notes:Browse to the Windows Azure web siteFor developers, we have a rich set of developer centersWe offer dev centers in multiple languages. If you’re a .NET developer…If you’re a Node developer, you can do the same thingAll of the SDKs are released as open source under an Apache 2 license. Sign-up for a free trialNavigate to different portal areas focusing on dashbaord
Speaker Notes:As you saw you can use both Windows Server or LinuxYou can install any software you want in the virtual machine. It’s your virtual machineYou can also setup a virtual private network to connect VMs to your on-premises infrastructure
Speaker Notes:Provision a new Linux machine. Provision a Windows machine.
Speaker Notes:There are a few aspects of the Windows Azure Virtual machines feature that I want to talk more about.One of the ability to have Virtual Machine Portability between Windows Azure and different environments. All of the virtual machines running in Windows Azure are using what we call the VHD file format. VHD is an open specification that we’ve released. We use VHDs in a variety of other products including Windows Server virtualization.
Speaker Notes:The benefit of using the same file format is that it’s really easy open file format is that it’s really easy …The benefit is that since we’re using an open file format, you have the ability to take a VM from your own data center and upload it to Windows AzureYou don’t have to run an import / export process. You simply upload it and it worksThere’s no conversion tools or agent you have to install in the VM, it just works. [Transit to next slide]
Speaker Notes:You can also take, for example, either the Windows or Linux VMs that we created in Windows Azure and we make it really easy for you to download the VHD locally and you can then boot it up on a local server in whatever environment that you want. Again you don’t have to export it or convert it, just click and download it. It’s not a one way street[Transit to next slide]
Speaker Notes:The other thing this offers is that it not only allows you to run in Windows Azure as a data center but it also allows you to run in other service providers as well.You can take VMs from any of these locations and move them into another data center[Transit to next slide]
Speaker Notes:The end result is that you have a lot of flexibility, a lot of portability, and ensures that you have no lock-in
Speaker Notes:The other neat thing that we’re doing with Windows Azure now is making it possible for you to mount durable drives to your virtual machine. We’re trying to do it in way that it is very reliable, consistent, and delivers a high performance.One of the things that’s different about how we enabled it is that when you mount a drive either in the portal or in the command line we are backing the disk with the Windows Azure Storage system that we’re running in the cloud todayThere are a couple nice characteristics about the storage system.Replication One is that we triple replicate the content within the data center. If a disk ever goes bad that you data is on then we have two other copies of the data that we can work with and we do not have any interruption of serviceWe can then spin up a new replica once we detect a disk is badFrom your VMs perspective you never know that an issue actually occurred[Transit to next slide]So you get much more reliability and an always on experience even when hardware failsNotes:Mentioned that Windows Azure Virtual Machines are backed by a durable store. Let’s spend a few minutes talking about how this works.
Speaker Notes:Another thing that is nice about the Windows Azure Storage solution is that we have support for Continuous storage geo-replicationWhat this means is that whenever you save something in the storage system, in the background we can automatically replicate the data to another datacenter. We guarantee that these data centers are several hundred miles apart so that in the case of a natural disaster or a complete data center failure you can be ensured that a copy of your data exists somewhere else. You don’t have to set anything up to enable it. It’s automatically enabled by default.You can turn it off if there are policy reasons why you wouldn’t want it enabled. The end result is that you can deliver more robust solutions with even greater integrity
Speaker Notes:TransitionVirtual machine capabilities are one of the great features as part of this Azure release.Next one I want to talk about are Windows Azure Web SitesBasically with Windows Azure Web Sites there is a managed service that you can use to run web sites and web APIs. You don’t have to worry or think about VMs, servers, or infrastructure. You can simply focus on building and deploying HTTP based applications.Enables you to build web sites using ASP.NET, Node.js, or PHPAllows you to use any tool and any operating system to build these sites including Windows, OS X, and Linux. You can easily deploy these sites using the tools and infrastructure you know. We support several flexible deployment options including FTP, GIT, and Team Foundation ServicesWhat is nice about this offering is that not only does it enable to very quickly get going, but it also allows you to start with a free offer in a shared environment. You can then scale up these sites using reserved instances for higher performance and isolation and scale out these sites as your web site becomes successful and you have increased load.
Speaker Notes:I’m going to show you three different web sites to show you the broad spectrum of scenarios that we’re enabling.First demo – a web site from a gallery.Second demo – new asp.net web site.Third demo – a PHP / Node.js web site.
Speaker Notes:We’ve talked about Virtual Machines and we’ve talked about Web Sites, now let’s talk about Cloud ServicesCloud Services is another model we support for building applications. Enables you to build what we sometimes refer to as infinitely scalable applications. They can support 1 to hundreds or thousands of courseSupport not only web based deployments, but also multi-tier architectures where you might have a combination of front ends, middle tiers, as well as virtual machines running as part of your solution.Supports automated application management, so it is really easy to deploy, scale out, isolate, and recover from any type of hardware failure. As well as support for automated updates.
Speaker Notes:Possible demos:Continue with previously built ASP.NET web site and convert it to a Cloud Service.Create a new Cloud Service with a Web Role and a Worker Role with Service Bus Queue. Use Server Explorer to generate test messages to be handled by the Worker Role (set break point in Worker Role to observe the message).
Transition:Let’s spend a few minutes talking about what happens when we deploy a cloud service in Windows Azure.
Speaker Notes:All of these services can also be used from multiple languagesWe now have as part of our developer center on WindowsAzure.com support for multiple different languages including .NET, Node, Java, and PHP.One of the new languages that we’re now enabling is Python with a complete SDK and dev center. For each of these we provide libraries that you can consume that call into the REST APIs that we expose for the building block services. You can also call the REST APIs directly
Speaker Notes:All of the libraries are hosted on GitHub under an Apache 2 licenseSo you can both see the source and contribute back to the source
Slide Objectives:Explain that there are different VM instance sizes available within Windows AzureSpeaking Points:---Speaking Points:One of the key areas of feedback has been to reduce the cost and size of Windows Azure instances. At PDC we will announce..Notes:(*) 20GB with a limitation on VHD size if they are deploying VMRole on XSmall: the VHD can only be up to 15GB.each tenant can support 20 instances just like regular subscriptions with Small VM. We do not scale based on core counts.There is no SLA on the network bandwidth for each VM size as this resource is shared among all the VM. That said, we need to provide guidance for customer so they could design their applications correctly. From the engineering side, this is what we mean by Low, Moderate and High. • Low currently means 0-15Mbps with short burst up to 25-50Mbps (Megabit/s). These are sufficient for some web sites with low traffic. • Moderate means 0-100Mbps with short burst up to 200Mbps (100Mbps is the norm). This is what we currently reserve for the Small VM.• High means 200-800 Mbps. If you divide this into 3 spectrums for Medium, Large and XL. Then Medium is in the low end, Large hovers around the middle zone and of course XL takes the high-end spot.These rates should be used as guidance. Nothing can beat a test run to see what the application requires but using these bandwidth ranges, hopefully it reduces the guess work for the customers
Speaker Notes:As of this month,Windows Azure is now available in over 89 countries and territories.Anyone within these countries can sign up for a free trial or a paid subscription to use Windows Azure servicesOf course you can build and deliver solutions to any of your customers worldwide.
