2-->PaaS

3-->SaaS

Geographical dispersement:

1--> Availability Zones (Az's)  --Logical group of Datacenters 

2--> Edge Locations  --Point of presence services used to deliver the content (such as Cloud front ,CDN (Content Distribution Network))

Infrastructure Usage (EC2)

       -- On demand --Which is where you only pay for the instance as long as its running or using.

Pricing concept 

include paying for infrastructure usage  using EC2

 

when using Amazon S3 , DynamoDB for 

Data usage and transfer

Global infrastructure services include IAM( Identity and Access management)

 

    Network , storage , database

    

Application services 

    SNS ,SQS ,SWF

    

Deployment and management services

Elastic Beanstalk , cloud formation

AWS features:

--------------

--Management console   ---- AWS web interface

--CLI  (Command line interface)   --commands for AWS wide set of products

--AWS SDK              ---> APIs that are specific to programming languages

--command line tools   -->  command for individual AWS products

-- Query API     -->  Low level APIs that are accessible using http requests.

A)Compute 

AWS EC2 (Elastic Compute Cloud)

 

        1)--AWS EC2    -->Virtual servers in Cloud

        2)--AWS EC2 Container services --->Run and manages Docker Containers

        3)--AWS Lambda  --->Run code in response to events

        4)--AWS EC2 Container Registry --->Store and  Retrieve Docker images

        5)--AWS LightSail              ---> Launch and manage virtual private servers

        6)--AWS VPC (Virtual private cloud) --> isolated cloud Resources

        7)--AWS Batch                  --> Run batch at any scale

        8)--AWS Elastic BeanStalk      --> Run and manage web applications.

        9)--AWS Scaling                -->Automatic Elastic

        

 

        

  1)AWS EC2

 

      re-sizable  cloud based virtual server

      

      features

        

             --Removes necessity of upfront investment for h/w

             --pay for only used quantity

             --manage numerous instances simultaneously 

             ---Easy web scale cloud computing

             

             

       2) AWS ECS (Elastic Container Service)

       

       

           Scalable performance container service to include Docker containers

           

           

           --Removes the necessity to install, run , manage and scale cluster infrastracture

       

       3)AWS Lambda

       

           Aims to run code without managing provisioning servers.

           Runs code in response to events

           

           Lambda is nucleus of serverless computing 

           

           Run code virtually any type of backend services or applications without administration

           

           Create code to automatically triggers from other AWS services otherwise call it directly from mobile app or web app.

           

B)Storage  in AWS Cloud

Provides complete set of cloud storage  services to support archival and application compliance need

Backup and archive applications and DB, IOT, Datawarehouses and Big data analytics.

-- AWS S3 (Simple Storage Service)

   --Provide safe ,secure object storage.

   --Easy to use with simple web service interface to store and retrieve any amount of data at any time from anywhere on the web.

   --Automatically  copy of data on multiple devices at multiple facilities

   --Let you preserve, retrive , restore every version of object on S3 bucket.

   --Pay actually for what you use.

   --Archive data on amazon Glacier .no cost of archive service.

   --Authenticate user on identity and access control on manage bucket policies, ACLS, query string authentication

   --Helps you securely upload and download data with SSL encrypted endpoints  

   

   

   Amazon Glacier 

   

    Cloud storage service for long time backup and archiving.

   

   Amazon Elastic File system (EFS):

   

    Shared file system used with Amazon Ec2

   

   Amazon Database :

   

                Amazon RDS (Relational databases)

                DynamoDB  ---NO sql DB service

                

                Amazon Aurora ---My SQL compatible relational DB with 5 times performance.

                

                Amazon Elastic Cache --in memory cache service Memcached and redis support.

                

                Amazon Redshift -- a petabyte-scale datawarehouse service.

      According to Forrester, Amazon DynamoDB is the most popular NoSQL cloud database.
