Amazon Web services...a walk through the cloud


I am amazed by the wide spectrum of services that Amazon Web Services provides. 

Need to deep dive into this VIRTUAL MALL of resources that I feel can suit outfits/corporate of any size financially or strength wise. Corporate World is going to be surprised with the money saved and the value for that money they have invested in cloud. 

Today I am going to talk about various Services provided by AWS.



NETWORK AND CONTENT DELIVERY


VIRTUAL PRIVATE CLOUD i.e  VPC is A virtual private cloud (VPC) is a virtual network that closely resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of Amazon Web Services (AWS).

ROUTE 53 is Amazon DNS Services for

Register domain names
Route Internet traffic to the resources for your domain 
Check the health of your resources 

CLOUDFRONT Accelerates the delivery of websites,videos,API's

DIRECT CONNECT  Connection between ON Premise and AWS CLOUD is achieved using Direct Connect.


COMPUTE


Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. In simple words it gives us the ability to create virtual machines of different configurations

Amazon EC2 Container Service (ECS) is a highly scalable, high performance container management service that supports Docker containers and allows you to easily run applications on a managed cluster of Amazon EC2 instances

AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP etc
You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring.

AWS Lambda lets you run code without provisioning or managing servers


STORAGE


Amazon Simple Storage Service (Amazon S3) is object storage with a simple web service interface to store and retrieve any amount of data from anywhere on the web. One can look at it as virtual disks in the cloud to store various objects like files, videos, photographs etc

Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup. Data that needs to be maintained for legal purposes etc can be stored in Glacier. Retrieval can take 4-5 hours.

AMAZON EFS is Elastic File System to me is similar to NFS but it in the cloud. It is a block based storage that can be shared between multiple Virtual machines.

STORAGE GATEWAY is used to connect S3 to on premise data centers.

Amazon Elastic Block Store (Amazon EBS) provides persistent block storage volumes for use with Amazon EC2 instances in the AWS Cloud
