Are we satisfied with your traditional infrastructure?

the demand increases fast?

What happens if...

What happens if...● Slow and manual process to

improving the system's capacity

● Possibility of high delay and unavailability of the systems

● It’s hard to know where decrease the capacity again if the demand come back to normal

What happens if...

...you overestimate the infrastructure capacity?

What happens if...

… occurs a blackout in server’s location?

What happens if...

What happens if...

● High costs and time to deploy the applications in another locations or lead with the problem

… someone removes some server’s critical system file?

What happens if...

What happens if...

● Long time to lead with systems problems

Web Service that provides scalable compute capacity

in the AWS.

What happens if...

What is Amazon EC2?● Reduced time to obtain and boot new server to minutes● Fast resizable compute instances● Multiple instances types, operating systems● Automatically scale up and down depending on its needs● Applications can be hosted in multiple locations world-wide● Pay for what is used

EC2 Instance storeEBS - Elastic Block StoreS3 - Simple Storage Service

Storage

EC2 Instance store

Temporary block level storage;

If the instance stops or terminate, any data in instance store volumes is lost;

Can’t be detached from an instance and attached to another

Storage

Elastic Block Store (EBS)

Persistent block level storage;Low-latency;Automatically replicated within its AZ;Can only be used by EC2 instances;Appears as a mountable volume;Can be transported between virtual machines;

Storage

Simple Storage Service (S3)

Storage for internet data

Files accessible using HTTP protocols

S3 typically experiences write delays while EBS does not

Inexpensive

Storage

Application Machine Images (AMI) and Instances

AMI:

● Contains the software configurations (OS, application server, applications);

● Used to launch instances;● Can be customized and saved.

INSTANCES:● A copy of AMI running as a virtual server in cloud.● Different types of instances can be launch by the same

AMI.

Application Machine Images (AMI)

Instance Store Backed

EBS Backed Instance

Instances Classification

Family: General purpose, Compute optimized, GPU instances, Memory optimized, Storage optimized;

Type: t2.nano, t2.microFree tier eligible, t2.small, m4.large, c3.8xlarge, d2.8xlarge, i2.xlarge, i2.2xlarge, i2.4xlarge, i2.8xlarge....

Use Case: Stayfilm

Creating EC2 instances

Conclusions

● Reduced time scale systems● Automatically scale● Easy to use with habitual computing concepts● A large number of components types compatible applications● Easy way to expand your application around the world with

low latency● Safe money in systems with variable demands
