Section -2

1.The AWS Platform - Structure diagram- Refer AWSPlatformServices for exam

2.Global infrastructure -

a)Region-Regional location- is the place where servers are physically placed. - may consist of multiple availability zones - eg 2 or 3. Ref Region.gif

The multiple availability zones in a region mostly will be independant of each other.
b)availability zones - a physical data center

c) Edge locations - are CDN endpoints for cloud front

CDN- Content delivery networks. A package of data. Say the data is in Texas and is requested for in NJ, it travels one time to NJ and is stored in cache in a edge location. For any further requests for the same data from NJ the data doesnt travel again.

There are many more edge locations than regions-eg refer North America Region Edgelocations Map.gif

 

3.Services

a) Networking & Content Delivery

VPC- Virtual private cloud - (A virtual data center)

Route 53 - Amazon's DNS- look up public IP address  53 DNS port named after I63

Cloud Front - bunch of edge locations

Direct Connect - Physical direct telephone line between AWS and business network

 

b) Compute

EC-2 - Virtual machine in the cloud

EC 2 container service - highly scalable, powerful container management service(CMS) using docker containers - Used for clustering

Elastic bean stalk- It lets you upload your code directly to aws, and the bean stalk goes over your code and takes care of provisioning all the infrastructure needed for it

Lambda - Serverless - no access to virtual machines

Light sail - will autodeploy. for those who dont know AWS

 

c) Storage - refer Storage.gif

S3 - virtual disc in cloud for object based storage- where you can store object - Objects are files - eg media,excel etc But not a db- Simple storage service

Glacier - archive files from S3

EFS - Elastic file service - File based storage and you can share it. You can install DB, applications and can be shared to multiple virtual machines.

Storage gateway - to connect S3 to your own premises or head quarters- its a virtual machine of which you get an image and it connects with s3

 

d) Databases

RDS - relational database services - It has got number of DB technologies- mysql, sql,poster sql,oracle,arora,maria db

Dynamo DB - No sql DB, extremely scalable

Redshift - Amazon's Data warehousing solution. uses BigData

Elasticache- Caching in cloud. Frequently visited part of a website/application may be cached with Elasticache and thus removing the load off of DB

 

d) Migration Services

Snowball - import export data to amazon. Its briefcase size application to which you can load terrabytes of data and it connects back to aws- which transfers it to S3.

Snowball edge is the recent upgrade to this

DMS - Database migration services - Transfer/Migrate DBs to cloud, redshift etc. The original DB can also be migrated to something else on AWS - like Oracle on ur premise to arora on AWS

SMS - Server migration services. Migrates servers to cloud- especially useful to migrate the VMs in your premise to cloud. Can migrate 50 servers concurrently

 

e) Analytics

Athena - Lets run sql queries on S3 objects(files). Essentially converts your csv/json files to searchable databases

EMR- used for big data - like log analysis, financial reporting- at the base it uses hadoop

Cloud Search- Used to create search engine for your website or application. Cloud and Elastic search are similar. Cloud search-fully managed search provided by amazon, elastic is open source

Elastic Search

Kinesis - Realtime analysis/streaming of large data- terra bytes in an hour. usage eg - financial transactions, social media feeds, sentiment analysis for a product

Data pipeline - To move/migrate data . eg migrate data from s3 to dynamo db and vise versa

Quick Sight - Display/Dashboard building based on your data in cloud. Business Analytic tool

 

f)Security  and Identity

IAm - identity & Access management - Assigning access, users etc

Inspector - agent you can install on your virtual machine and it'll give security reports of the processes running on the vm

Certificate manager - Free ssl certificates to use on your domain names

Directory service - Like Microsoft active directory

WAF - Web application firewall - Application level protection. Traditionally firewall protects network level protection. this one provides application level

prevents cross site scripting, sql queries etc

Artifacts - way to access compliance documents

 

g)Management tools

Cloud watch - monitors AWS environment, you can get cpu utilization, vm utilization, disc utilization

Cloud formation - transform infrastructure to code. The commands etc to put together cloud templates to create/deploy the cloud

Cloud trail - auditing your AWS resources. eg trail to track someone adding user etc

Opsworks - automating deployments using chefs - wats shifts need to research

Config - Configuration rules/alerts so the auditing or notification is set when the condition configured is met

Service Catalog - lets you to configure the authorisation on certain services and not on certain services on each of your ec 2 service

Trusted advisor - aws environment advisor, tips for performance customization etc

 

h)Applications

Step functions - A way to visualize wats going on in the application- the micro services that are part of the bigger service

SWF- Simple workflow - It facilitates the fulfillment of an order that includes human and automated tasks- Its used in Amazon fulfillment centers

API Gateway- Doorway to access the backend services. Lets you create, manage maintain services which your app uses to access backend data.

AppStream - Streaming desktop apps to users

Elastic Transcoder - Used with videos, converts any video format to a type compatible to the receiving/client devices

 

i)Developer Tools

Codecommit- Its github in the cloud . Lets u store your code open or closed

CodeBuild- To build your code on cloud. Paid by per minute

Code Deploy-Deploy your code to EC2 instance in an automated & very regulated fashion

CodePipeline- Version control - track different versions of code like test,stage,uat etc

 

j) Mobile Services

Mobile hub- add,create & design services for your mobile app- includes user authentication, data storage, push notifications etc

AWS has a separate console for mobile apps which is part of Mobile hub

The console has different parts listed below.

Cognito - helps to integrate sign in/sign out to your apps , helps integrate with different socio identity providers

Device Farm- Farm of different devices- provides an environment for you to test your android ios, fire os apps in a farm of different devices

Mobile Analytics - cost effective and efficient way to analyse mobile data

Pinpoint - engage with your app user/get data on user behaviour- its google analytics combined with targeted marketing

 

k)Business Productivity

Workdocs - Store ur work docs in clouds tied with lot of security

Workmail - exchange in AWS - for sending and receiving emails gateway

 

l) iOT- to keep track of millions of devices

 

m) Desktop & App Streaming

Workspaces - like thin client with os installed in cloud workspaces

AppStream 2.0- Stream desktop applications to your users

 

n)Artificial Intelligence

Alexa - AWS voice service. When you talk to echo it talks to Alexa which connects with the services through lamda

Lex- No need of echo to communicate with alexa. Lex can be embedded within any software

Polly- text to voice service- that's there within alexa

Machine Learning - Feed data set to AWS and the outputs of it ...This will let it predict the output for a similar future dataset

Rekognition - feed a picture and it'll give you the objects in it like a bike, outdoors etc

 

o)Messaging

SNS - Simple notification service - email, sms, publishing

SQS - Queue system - decoupling a application from the message so the app even if its down it can pick the message from the q once it comes back at up
