Cloud Service Models

Home Cloud Cloud Service Models

Today, the industry recognizes three distinct cloud service models, each providing a different trade-off between control/flexibility and total cost.

  • Infrastructure as a Service (IaaS): Virtual infrastructure hosting virtual machines and mostly existing applications e.g. Windows Azure, Amazon EC2
  • Platform as a Service (PaaS): Cloud application infrastructure that provides on-demand application-hosting environment e.g. Windows Azure
  • Software as a Service (SaaS): Cloud service model where an application is delivered over the Internet and customers pay on a per-use basis e.g. Office365 – SharePoint Online, Exchange Online, Skype for Business; Project Online, and CRM Online.
Cloud Architecture and Deployment choices

Consider the business risk of running applications or workloads on a private, public, or hybrid cloud platform.

Does the application or data contain private or sensitive information?
Do you need to comply with any regulatory requirements or sovereignty laws?
Should you migrate an application, or just the web tier, leaving the data on your premises?

Our consultants can review your application needs with your organization’s development, operations, and security teams to find solutions. Our Cloud consultants focus on symmetry between System Center Virtual Machine Manager based private cloud and Windows Azure / AWS EC2 public clouds, helping design the architecture that fits your specific needs.

SharePoint and Windows Azure

When you use the cloud as a place to deploy applications, your reach naturally widens. For example, by deploying your services and applications in Windows Azure, you make the available to many SharePoint clients.

Traditional storage costs can be high, and the need to quickly access, store, and archive digital assets (documents, media, etcetera) will only increase over time.

By utilizing remote file storage, such as Windows Azure storage and data management in SQL Azure, in conjunction with SharePoint Server, you can reduce resource costs while providing greater value to internal and external customers.

SQL Server and SQL Azure

SQL Azure data sync helps enterprises to quickly share data between both on-premises and cloud databases. The “hub and spoke” model of SQL Azure Data Sync addresses complex business needs by allowing for bi-directional flow of data.

Bi-directional flow creates symmetry between on-premises and SQL Azure databases as changes to either location are automatically synced.

Migration Business Scenarios

Running applications like public-facing websites, mobile web campaigns, and/or high-performance computing workloads? Migration to Windows Azure will benefit you in terms of agility, scalability, availability, and operating costs.

Amia Infotech has expertise in using assessment tools that help your organization plan for Windows Azure, including automated discovery and inventory reporting of web applications, IIS servers, and SQL databases.

Which applications can be migrated to Windows Azure?
Perhaps your existing application can be extended to use the cloud in peak times, and/or use Azure to support specific test scenarios?

Our Cloud Decision Accelerator offering provides an integrated assessment and analysis across public cloud services (Windows Azure, Office 365, Project Online and CRM Online).

The Migration Assessment for Windows Azure Platform helps you understand what is required to move to Windows Azure by providing a report with specific recommendations about how to plan a full migration, based on risk and priority.

Cloud Computing Business Scenarios

Having sufficient capacity to meet fluctuating demand without wasting resources is a key issue for most enterprises today. With nearly infinite capacity and processing power the cloud creates whole new possibilities for applications that would have been cost-prohibitive in a traditional infrastructure. Assess Cloud Computing in the following business scenarios,

  • Have a need for a high-traffic website?
  • Want to build a digital marketing campaign around social networking?
  • Need to run hundreds or thousands of servers for batch processing, analytics, video transcoding, or scientific research?
  • Have a mobile initiative for delivering applications to customers?
  • Have a large amount of files, videos, or other data you want to “host” and serve to customers?
  • Want to move departmental or line-of-business applications to the cloud?
Cloud Usage Patterns

Most businesses application usage falls into one or more of four basic usage patterns. By leveraging the clouds metered service and elasticity businesses can often find significant savings through eliminating the need for unnecessary infrastructure and the inefficiencies of having unused resources.

  • On-Off: Your business has predictable times of application usage activity and inactivity.
  • Growing Fast: Your business usage is in a state of growth and usage is continually increasing.
  • Spikey Predictable: Your business experiences high usage periods at predictable times, such as a holiday rush, or tax season type of events.
