EC2 and S3 are core AWS services. EC2 provides virtual servers and S3 provides cloud storage. EC2 instances run on different hardware types and can be configured with operating systems and software. S3 stores files and objects accessed via unique buckets. EBS provides persistent block storage volumes for EC2 instances, while S3 provides scalable cloud storage. VPC allows creation of virtual private networks within AWS.

1. Amazon web service
EC2 & S3 Overview

2. EC2
EC2 is an instance that is used for all compute work inside AWS.
It can be used as:
● Separate virtual machine with OS
● Load Balancer
● Part of RDC and other clusters
● etc

3. AMI
Operation System + Software = Amazon Machine Image
● Used for app scaling purposes
● Migration between regions and AZ

4. EC2 instances types
● General purpose
● Compute optimized
● Memory optimized
● Storage optimized

5. Storage
● Elastic Block Storage (EBS)
● Instance Store
● Elastic File System (EFS)
● Simple Storage Service (S3)

6. Instance Store
Instance store provides temporary block-level storage for your
instance.
Instance store is ideal for temporary storage of information that changes frequently, such as
buffers, caches, scratch data, and other temporary content, or for data that is replicated across a
fleet of instances, such as a load-balanced pool of web servers.
The data in an instance store persists only during the lifetime of its associated instance. If an
instance reboots (intentionally or unintentionally), data in the instance store persists. However, data
in the instance store is lost under the following circumstances:
● The underlying disk drive fails
● The instance stops

7. Elastic Block Store

EBS

8. Elastic Block Store
● EBS volumes are highly available and reliable storage volumes that can be
attached to any running instance that is in the same Availability Zone.
● Encryption available (temp EC2 store -> EBS)
● Volumes are up to 16TiB
● Types:
○ General purpose SSD (3 IOPS/GiB; up to 10,000 IOPS and 160 MB/s of throughput)
○ Provisioned IOPS SSD (up to 20,000 IOPS and 320 MB/s of throughput)
○ Throughput Optimized HDD (throughput of up to 500 MiB/s,)

9. Elastic File System
Amazon EFS provides scalable file storage for use with
Amazon EC2.
Main feature is to easily customize file system for multiple
instances.

10. VPC

11. VPC
VPC - logically isolated cloud section in AWS.
Features:
● All instances launches inside VPC
● Separation for public and private networks
● Ability to connect to private network via VPN
● Using S3 locally

17. Bucket features
● Bucket names should be unique through all AWS
● Bucket name is used to generate link to get access from browser or app
● Cross-region replication (copy to only one other region)

new services

22. Amazon re:Invent 2016
Computing:
● New Instances:
○ R4 - up to 64 vCPUs and 488 GiB of memory
○ t2.xlarge (16 Gib of memory) and t2.2xlarge(32 Gib of memory)
○ F1 - give you access to FPGA. You can write code that runs on the FPGA and speeds up
many types of genomics, seismic analysis, financial risk analysis, big data search, and
encryption algorithms by up to 30 times
○ New C5 Instances - Intel’s brand new Xeon “Skylake” processor (up to 72 vCPUs and 144
GiB of memory.)
● Elastic GPUs - EC2 instance types, with your choice of 1 GiB to 8 GiB of GPU memory and
compute power to match.

LightSail

26. Amazon re:Invent 2016
Amazon Athena - a new serverless query service that makes it easy to
analyze large amounts of data stored in Amazon S3 using Standard SQL.
Features:
● You pay only for the queries that you run.
● Behind the scenes, Athena parallelizes your query, spreads it out across hundreds or
thousands of cores, and delivers results in seconds
● Queries are expressed in standard ANSI SQL and can use JOINs, window functions, and other
advanced features
● Can query data in many different formats including JSON, CSV, log files, text with custom
delimiters, Apache Parquet, and Apache ORC.
