What is Amazon DynamoDB ? Describe its benefits.

 AMAZON DYNAMO

  • Amazon offers DynamoDB, a fully managed proprietary NoSQL database service that supports key-value and document data formats, as part of the Amazon Web Services portfolio. DynamoDB provides a comparable data architecture to Dynamo and gets its name from it, but it has a distinct underlying implementation. DynamoDB employs synchronous replication over many data centers for high durability and availability, and it has a multi-master design that requires the client to resolve version conflicts.
  • Amazon DynamoDB is a key-value and document database that promises performance in single-digit milliseconds at any size. It is a fully managed, multiregional, multi-master database for internet-scale applications that has built-in security, backup and restore, and in-memory caching. DynamoDB can handle more than 10 trillion requests per day, with peaks of more than 20 million requests per second. Many of the world's fastest-growing companies, like Lyft, Airbnb, and Redfin, as well as corporations like Samsung, Toyota, and Capital One, rely on DynamoDB's scale and performance to serve mission-critical workloads. Hundreds of thousands of Amazon Online Services customers have selected DynamoDB as their key-value and document database for mobile, web, gaming, ad tech, IoT, and other applications requiring low-latency data access at any scale. Create a new table for your application and leave the rest to DynamoDB.
  • DynamoDB is distinct from other Amazon services in that it allows developers to pay for a service based on throughput rather than storage. If Auto Scaling is enabled, the database will automatically scale. Administrators may also request throughput modifications, and DynamoDB can distribute data and traffic over many servers utilizing solid-state disks, resulting in predictable performance.



Benefits

Performance at scale -

 DynamoDB provides reliable, single-digit millisecond response speeds at any size, enabling it to serve some of the world's biggest scale applications. You can create apps with nearly mitless throughput and storage. DynamoDB global tables replicate your data across different AWS Regions to provide quick, local data access for globally dispersed applications.


Serverless - 

There are no servers to deploy, patch, or manage with DynamoDB, and no software to install, or maintain performance. Availability and fault tolerance are built-in, so you do not have to structure maintain, or run. your applications to support these features. DynamoDB supports both provisioned and on-demand DynamoDB adjusts tables up and down automatically to accommodate capacity while capacity options, allow you to save money by setting capacity per job or paying for just the resources you use.


Enterprise-ready 

DynamoDB provides ACID transactions, allowing you to create mission-critical control for all of your tables. You can generate comprehensive backups of hundreds of terabytes of data in applications at scale. By default, DynamoDB encrypts all data and offers fine-grained identity and access - downtime. DynamoDB is also supported by a service level agreement to ensure uptime.

What are different steps used in JDBC? Write down a small program showing all steps.

-
 T he fundamental steps involved in the process of connecting to a database and executing a query consist of the following: Import JDBC packages. Load and register the JDBC driver. Open a connection to the database. Create a statement object to perform a query. Execute the statement object and return a query resultset. Process the resultset. Close the resultset and statement objects. Close the connection. These steps are described in detail in the sections that follow. 1. Import JDBC Packages This is for making the JDBC API classes immediately available to the application program. The following import statement should be included in the program irrespective of the JDBC driver being used: import java.sql.*; Additionally, depending on the features being used, Oracle-supplied JDBC packages might need to be imported. For example, the following packages might need to be imported while using the Oracle extensions to JDBC such as using advanced data types such as BLOB, and so on. import o...

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Pure Versus Partial EC

Image
Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online. Partial E-Commerce on the other hand refers to a slightly opposite situation where a business has an online presence, but still has a physical location for the goods and services it sells. For example, Amazon, Walmart, and any other you can think of. you buy the goods online but receive them physically.                   ...
