AWS Database Services - AWS Auro, AWS DynamoDB, and AWS ElastiCache


As we have already discussed about what is AWS Database service in our last blog if still you have not go thought it then check by clicking the AWS Database Services details  and understand it.

Here we are resuming our last blog by intruding and explaining the  AWS Auro, AWS DynamoDB, and AWS ElastiCache Database services.


AWS Database Services - AWS Auro, AWS DynamoDB, and AWS ElastiCache




What Is Amazon AWS Aurora Database?


Amazon Aurora is fully managed by Amazon RDS. It is a relational database engine built for the cloud. Amazon Aurora is also completely compatible with MySQL. Since Amazon Aurora is fully managed by RDS, all administrative tasks such as database setup, patching, backups, and more are automated.

Following are some of the benefits of using Amazon Aurora:
  • It provides high performance and scalability.

  • It’s highly secure.

  • It offers high availability and durability.

  • It’s fully managed.


What Is Amazon AWS DynamoDB?


Amazon DynamoDB is a fast, fully managed, and flexible NoSQL database. It also supports document-based data. AWS affirms that DynamoDB delivers single-digit millisecond performance at any scale. DynamoDB comes with built-in Security, Backup, and Restore features.

Since DynamoDB is a NoSQL database, it doesn’t require any schema. In DynamoDB, there are basically three core components:

Tables:
The collection of data is called a table in DynamoDB. It’s not a structured table with a fixed number of rows and columns.

Items:
Tables in DynamoDB contain one or more items. Items are made up of a group of uniquely identifiable attributes.

Attributes:
Attributes are the data elements or values that reside in each item. They are equivalent to data values in a relational database that reside in a particular cell of a table.

Following are some of the benefits of using Amazon DynamoDB:
  • Easy to set up and manage

  • Data is automatically replicated across multiple Availability Zones

  • Supports both key–value and document-based data models


What Is AWS ElastiCache?


Amazon ElastiCache is a fully managed caching service that offers high-performance, cost-effective, and scalable caching solutions. Amazon ElastiCache provides two caching engines, namely, Memcached and Redis.




Why Do We Need AWS ElastiCache?


There are various benefits of using Amazon ElastiCache. Besides being easy to set up and deploy, ElastiCache also improves applications’ performance as it reduces disk reads. Following are some of the main reasons why ElastiCache is immensely useful:
  • Response time: ElastiCache reduces the response time as it retrieves data from a fast in-memory system. It reduces the dependence on disk-based databases which are usually slower.

  • Scalability: Amazon ElastiCache is designed to be able to modify itself, automatically. It can scale out or scale up depending on the fluctuating application requirements.

  • Complete management: Amazon ElastiCache is fully managed, so the common administrative tasks such as hardware provisioning, failure recovery, backups, and more are all automated.

What is STP? - Explain Advantages and Disadvantages

The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. STP is a protocol. It actively monitors all links of the network. To finds a redundant link, it uses an algorithm, known as the STA (spanning-tree algorithm). The STA algorithm first creates a topology database then it finds and disables the redundant links. Once redundant links are disabled, only the STP-chosen links remain active. If a new link is added or an existing link is removed, the STP re-runs the STA algorithm and re-adjusts all links to reflect the change. STP (Spanning Tree Protocol) automatically removes layer 2 switching loops by shutting down the redundant links. A redundant link is an additional link between two switches. A redundant link is usually created for backup purposes. Just like every coin has two sides, a redundant link, along with

What are the Advantages and Disadvantages of TCP/UDP ?? Difference between TCP and UDP

As in previous blog we have define and explain about what is TCP and UDP and from now we are moving ahead with Advantages, Disadvantages and Difference of TCP and UDP but for this you have to know about TCP and UDP hence to understand it go for a What is TCP and UDP . Advantage of TCP Here, are pros/benefits of TCP: It helps you to establish/set up a connection between different types of computers. It operates independently of the operating system. It supports many routing-protocols. It enables the internetworking between the organizations. TCP/IP model has a highly scalable client-server architecture. It can be operated independently. Supports several routing protocols. It can be used to establish a connection between two computers. Disadvantages of TCP Here, are disadvantage of using TCP: TCP never conclude a transmission without all data in motion being explicitly asked. You can't use for broadcast or multicast transmission. TCP has no block boundaries, so you
