    Study Notes

    High Demand for Interactive Applications

    • Cloud computing is gaining popularity due to its ability to provide real-time responses and data analysis across different sources.
    • Interactive applications with high availability and data-intensive requirements are attracted to cloud computing.

    Cloud Computing Advantages

    • Enables batch processing and analysis of large amounts of data efficiently.
    • Hides operational complexity of parallel processing using programming models like Google's MapReduce and Yahoo!'s Hadoop.
    • Business enterprises are interested in discovering customer needs, buying patterns, and supply chains to make informed decisions.
    • Cloud computing enables analysis of large amounts of online data, making it an ideal solution for businesses.
    • Scientific experiments, such as the Large Hadron Collider (LHC), require massive data processing and can be done using cloud computing.

    Cloud Architecture

    • Cloud providers have physical data centers that provide virtualized services to users through the internet.
    • Cloud providers separate applications and data, and provide mechanisms for storing and accessing data.

    Cloud Storage

    • Blobs provide mechanisms for storing unstructured data.
    • Tables are used for storing structured data and can be accessed using ADO.NET Data Services.
    • Queues are used to store messages about tasks to be performed by Worker role instances.

    Windows Azure Storage

    • All data is replicated three times for fault tolerance.
    • Data is backed up in geographically distributed data centers.
    • Azure storage can be accessed by any Windows Azure application or any application hosted on another cloud platform.

    SQL Azure

    • Provides relational databases for applications that require them.
    • Built on Microsoft SQL Server.
    • Can be accessed via ADO.NET or other Windows data access interfaces.

    E-Governance

    • E-governance refers to the processes and structures needed to deliver electronic services to the public.
    • Cloud computing can improve e-governance by providing 24/7 services, regular updates, and secure data storage.

    Impact of Technology in E-Governance

    • High availability is required for e-governance systems.
    • Content needs to be regularly updated and information provided to the public.
    • Human resources need to be properly trained to maintain and secure e-governance systems.
