  • @apixelit suport Standard answer, "IT Depends"; I will PM you when I am in SG if you need to discuss.

  • What would be ideal for a smaller business? I have only just started with a couple of guys working under me. We don’t have a very expansive model, but still the expenditure for infrastructure itself overshadows our revenue. I am just looking to start working from home and accessing data from home itself. Meetings can happen at the coffee place.

  3. 3. What is cloud computing? 3 1Cloud computing is an information-processing model in which centrally administered computing capabilities are delivered as services, on an as-needed basis, across the network to a variety of user-facing devices. 1. Cloud Computing By Brain J.S. Chee & Curtis Fran Abstraction is a critical foundation concept for cloud computing because it allows us to think of a particular service:  an application  a particular communication protocol  processing cycles within a CPU  storage capacity on a hard disk Without thinking about a particular piece of hardware that will provide that service.
  4. 4. Abstraction 4 Layer 1 - Physical Layer 2 - Data Link Layer 3 - Network Layer 4 - Transport Layer 5 - Session Layer 6 - Presentation Layer 7 - Application Open Systems Interconnection (OSI) The OSI model provides for distinct roles for devices, services, and protocols that lie within each layer, and for specific ways in which the components in one layer interact with components in other layers. Open DataBase Connection ( ODBC) Application Driver Manager DSN Configuration Connector / ODBC Database In the ODBC model, a common query language is used, and an external file provides the configuration information required to make the application work with a specific database.

  5. 5. Grid Computing 5 According to Wikipedia: Grid computing is a form of distributed computing whereby a “super and virtual computer” is composed of a cluster of networked, loosely-coupled computers, acting in concert to perform very large tasks. This technology has been applied to computationally-intensive scientific, mathematical, and academic problems through volunteer computing, and it is used in commercial enterprises for such diverse applications as drug discovery, economic forecasting, seismic analysis, and back-office data processing in support of e-commerce and web services. What distinguishes grid computing from typical cluster computing systems is that grids tend to be more loosely coupled, heterogeneous, and geographically dispersed. Also, while a computing grid may be dedicated to a specialized application, it is often constructed with the aid of general purpose grid software libraries and middleware.
  6. 6. Cloud Computing - In a nut case 6 Deployment Models:  Public Cloud  Private Cloud  Community Cloud  Hybrid Cloud Delivery Models:  Software-as-a-Service (SaaS)  Platform-as-a-Service (PaaS)  Infrastructure-as-a-Service (IaaS) Infrastructure:  Distributed Infrastructure  Resource Virtualization  Autonomous Systems Resources:  Compute & Storage Servers  Networks Services  Applications Attributes:  Massive Infrastructure  Utility Computing  Pay-Per-Usage  Accessible via the Internet  Elasticity
  7. 7. Cloud Computing - Delivery Models 7 Cloud computing is a general term for anything that involves delivering hosted services over the network (typically Internet). Cloud computing services are broadly classified under three main categories: Software-As-A-Service Infrastructure-As-A-Service Platform-As-A-Service This is a software distribution model in which applications are hosted by a vendor/service provider and available to customers over a network. This is a way to rent hardware / Operating Systems / Storage and Network Capacity over the network, typically over internet. The service delivery model allows us to rent different capacities but build a virtual environment that suits our needs. * PaaS is NOT Virtualization. This is a provision model in which the equipments used i.e. storage, hardware, servers and networking are outsourced. The service provider owns the equipment and is responsible for hosting, running and maintaining these equipments.
  8. 8. Software-as-a-Service [SaaS] 8  Gives users the capability to use applications supplied by service provider.  Not suitable for applications that require real-time response, or hosting of local data.  Suitable for products like emails, billing and payroll.  Suitable for need to access over web or mobile. API Abstraction Core Connectivity Hardware Facilities
  9. 9. Platform-as-a-Service [PaaS] 9  Gives the capability to deploy consumer- created or acquired applications using programming languages & tools.  User has full control over the deployed application  Session Management  Device Integration  Sandboxes  Instrumentation and Testing  PaaS is not useful when application must be portable or proprietary programming languages are used. API Abstraction Core Connectivity Hardware Facilities Integration & Middleware
  10. 10. Infrastructure-as-a-Service [IaaS] 10  Gives the capability to provision processing, storage, network and computing resources.  Services offered  Server hosting  Web Servers  Storage  Computing Hardware  Operating Systems  Virtual Instances  Load Balancing API Abstraction Core Connectivity Hardware Facilities Integration & Middleware Data Metadata Applications API Presentation

  13. 13. Cloud Computing - Ethical Issues 13  The control is relinquished to third-party services  Risk: Unauthorized access, data corruption, service unavailability.  The data is stored on multiple sites administered by several organizations  Difficult to identify the source and entity causing the problems.  Multiple services interoperate across the network  Identity fraud and theft are impossible to identify due to lack of traceability.  Vendor lock-in
