What started as an experiment to use idle capacity has grown into the largest, most comprehensive cloud offering in the world. AWS offerings range from compute, network, storage, and backup to software like DevOps and database. My presentation slides talk about different services that Amazon is providing today and how these services operate.

3. What is Cloud Computing?
❖Cloud computing is the on-demand delivery of compute power, database
storage, applications, and other IT resources through a cloud services
platform via the internet with pay-as-you-go pricing.

6. Service Models:IaaS, PaaS, SaaS
Cloud computing providers offer their services according
to several classified service models called SPI.

8. AWS Global Infrastructure
➢A Region is a physical location in the world where we have multiple
Availability Zones.
➢Availability Zones consist of one or more discrete data centers, each with
redundant power, networking and connectivity, housed in separate facilities.
➢Edge Locations: is where end users access services at AWS. They are
located in most of the major cities around the world and are specifically used
by CloudFront(CDN) to distribute content to end user to reduce latency.
➢The AWS Cloud operates 42 Availability Zones within 16 geographic
Regions around the world.

12. Amazon Simple Storage Service(S3)
❖Highly scalable object storage.
❖Files are stored as objects and organized into
high-level folders called buckets.
❖Pay exactly what you use
❖Highly durable
❖Limitlessy scalable
❖Data in transit to and from the service is encrypted
using SSL.
❖A bucket has a flat directory structure.
❖You can use versioning to preserve, retrieve and
restore objects.
12

13. Bucket Properties
❖Versioning – If enabled, POST/DELETE result in the creation of new versions without
destroying the old.
❖Lifecycle – Delete or archive objects in a bucket a certain time after creation or last
access or number of versions.
❖Access Policy – Control when and where objects can be accessed.
❖Access Control – Control who may access objects in this bucket.
❖Logging – Keep track of how objects are accessed.
❖Notification – Be notified when failures occur.
13

14. Amazon Elastic Block Storage
❖Block storage-use it as you would use a hard disk.
❖Data persists independent of instance.
❖Ability to backup the data via snapshots to
Amazon s3.
❖Can store upto 16TB data per storage
❖Attach an EBS volume to any EC2 in same AZ
❖Different types
1.Solid-State Drives(SSD)
2. Hard disk drives(HDD)

15. Amazon Elastic File System (EFS)
Fully managed file system for EC2 instances
Provides standard file system semantics
Sharable across thousands of instances
between regions

SSD -based
Highly available and durable
NFS v4 based
Throughput and IOPS scale automatically as file
system grow.

20. What is Amazon EC2?
Amazon Elastic Compute Cloud (Amazon EC2)
Is a web service that provides secure, resizable
compute capacity in the cloud.
It is designed to make web-scale cloud computing
easier for developers.
It enables you to launch and manage Linux/UNIX
and Windows server instances in Amazon’s
data centers.
20

21. EC2 terminology
•Instance = One running virtual machine.
•Instance Type = hardware configuration: cores, memory, disk.
•Instance Store Volume = Temporary disk associated with instance.
•Image (AMI) = Stored bits which can be turned into instances.
•Key Pair = Credentials used to access VM from command line.
21

22. EC2 Pricing Model
Free Usage Tier
On-Demand Instances: Start and stop instances whenever you like, costs are rounded
up to the nearest hour. (Worst price)
Reserved Instances: Pay up front for one/three years in advance. (Best price)
Unused instances can be sold on a secondary market.
Spot Instances: Specify the price you are willing to pay, and instances get started and
stopped without any warning as the marked changes. (Kind of like Condor!)
