Knowledge Check
Q: What is the AWS term for physically distinct groups of data centers
within a region?
True or False: There are more regions than Edge locations.
True or False: AWS owns and maintains the infrastructure required
for application services and you provision and use them as needed.
Q: How do AZs in the same region differ?
Availability Zone (AZ).
False.
True.
Each Availability Zone is isolated, but the Availability Zones in a region are
connected through low-latency links.

AWS Infrastructure

Amazon Elastic Compute
Cloud (EC2)

Amazon Elastic Compute Cloud (EC2)
Resizable compute capacity
Complete control of your computing resources
Reduces the time required to obtain and boot
new server instances to minutesAmazon
EC2

Amazon EC2 Facts
Scale capacity as your computing requirements change
Pay only for capacity that you actually use
Choose Linux or Windows
Deploy across AWS Regions and Availability Zones for reliability

Launching an Amazon EC2 Instance via the Web
Console
1. Determine the AWS Region in which you want to launch the
Amazon EC2 instance.
2. Launch an Amazon EC2 instance from a pre-configured
Amazon Machine Image (AMI).
3. Choose an instance type based on CPU, memory, storage,
and network requirements.
4. Configure network, IP address, security groups, storage
volume, tags, and key pair.

AMI Details
An AMI includes the following:
A template for the root volume for the instance (for
example, an operating system, an application server,
and applications).
Launch permissions that control which AWS accounts
can use the AMI to launch instances.
A block device mapping that specifies the volumes to
attach to the instance when it's launched.

Amazon EBS vs. Amazon EC2 Instance Store
Amazon EBS
Ø Data stored on an Amazon EBS volume can persist
independently of the life of the instance.
Ø Storage is persistent.
Amazon EC2 Instance Store
Ø Data stored on a local instance store persists only as long as the
instance is alive.
Ø Storage is ephemeral.

AWS Marketplace – IT Software Optimized for the
Cloud
AWS Marketplace:
Is an online store to discover,
purchase,and deploy IT software on top
of the AWS infrastructure.
Ø Catalog of 2300+ IT software solutions
• Including Paid, BYOL, Open Source, SaaS, &
free to try options
Ø Pre-configured to operate on AWS
• Software checked by AWS for security and
operability
Ø Deploys to AWS environment in minutes
Ø Flexible, usage-based billing models
Ø Software charges billed to AWS account
Includes AWS Test Drive.

Choosing the Right Amazon EC2 Instance
EC2 instance types are optimized for different use cases and come
in multiple sizes. This allows you to optimally scale resources to
your workload requirements.
AWS uses Intel® Xeon® processors for EC2 instances, providing
customers with high performance and value.
Consider the following when choosing your instances: Core count,
memory size, storage size and type, network performance, and
CPU technologies.
Hurry Up and Go Idle - A larger compute instance can save you time
and money, therefore paying more per hour for a shorter amount of
time can be less expensive.

Intel® Processor Technologies
Intel® AVX – Get dramatically better performance for highly
parallel HPC workloads such as life science engineering, data
mining, financial analysis, or other technical computing
applications. AVX also enhances image, video, and audio
processing.
Intel® AES-NI – Enhance your security with these new
encryption instructions that reduce the performance penalty
associated with encrypting/decrypting data.
Intel® Turbo Boost Technology – Get more computing
power when you need it with performance that adapts to
spikes in your workload with Intel® Turbo Boost Technology
2.0

Current Generation Instances

Amazon
VPC

VPCs and Subnets
A subnet defines a range of IP addresses in your
VPC.
You can launch AWS resources into a subnet that you
select.
A private subnet should be used for resources that
won’t be accessible over the Internet.
A public subnet should be used for resources that will
be accessed over the Internet.
Each subnet must reside entirely within one Availability
Zone and cannot span zones.

Use groups to assign permissions to IAM users.
Grant least privilege.
Configure a strong password policy.
Enable MFA for privileged users.

AWS IAM Best Practices (cont.)
Use roles for applications that run on Amazon EC2
instances.
Delegate by using roles instead of by sharing credentials.
Rotate credentials regularly.
Remove unnecessary users and credentials.
Use policy conditions for extra security.
Monitor activity in your AWS account.

AWS Resource-Based Policies
Are an alternative to IAM and supported by some
services.
Grant cross-account access to your resources.
Use a principal to uniquely identify account in the policy.
Supported AWS services include :
Ø Amazon S3 Bucket Policy
Ø Amazon SNS Topic Policy
Ø Amazon SQS Queue Policy
Ø Amazon Glacier Vault Policy
Ø AWS OpsWorks Stack Policy
Ø AWS Lambda Function Policy

Amazon
RDS

Amazon RDS Use Case
We were able to go from
concept to delivered product
in about six months with just
a handful of engineers.
Greg Scallan
Chief Architect, Flipboard
”
“ Flipboard is an online magazine
with millions of users and billions of
“flips” per month.
Flipboard is one of the world’s first
social media magazines.
Flipboard uses Amazon RDS and
its Multi-AZ capabilities to store
mission critical user data.

Amazon RDS
Simple and fast to deploy
Manages common database administrative tasks
Compatible with your applications
Fast, predictable performance
Simple and fast to scale
Secure
Cost-effective

How Amazon RDS Backups Work
Automatic Backups:
Ø Restore your database to a
point in time.
Ø Are enabled by default.
Ø Let you choose a retention
period up to 35 days.
Manual Snapshots:
Ø Let you build a new
database instance from a
snapshot.
Ø Are initiated by the user.
Ø Persist until the user deletes
them.
Ø Are stored in Amazon S3.

Cross-Region Snapshots
Are a copy of a database
snapshot stored in a
different AWS Region.
Provide a backup for
disaster recovery.
Can be used as a base
for migration to a
different region.

Amazon RDS Security
Run your DB instance in an Amazon VPC.
Use IAM policies to grant access to Amazon RDS resources.
Use security groups.
Use Secure Socket Layer (SSL) connections with DB instances
(Amazon Aurora, Oracle, MySQL, MariaDB, PostgreSQL, Microsoft
SQL Server).
Use Amazon RDS encryption to secure your RDS instances and
snapshots at rest.
Use network encryption and transparent data encryption (TDE) with
Oracle DB and Microsoft SQL Server instances.
Use the security features of your DB engine to control access to
your DB instance.

A Resilient, Durable Application Architecture

Amazon RDS Best Practices
Monitor your memory, CPU, and storage usage.
Use Multi-AZ deployments to automatically provision and maintain a
synchronousstandby in a different Availability Zone.
Enable automatic backups.
Set the backup window to occurduring the daily low in WriteIOPS.
To increase the I/O capacity of a DB instance:
Ø Migrate to a DB instance class with high I/O capacity.
Ø Convert from standard storage to provisioned IOPS storage and use a DB
instance class optimized for provisioned IOPS.
Ø Provision additional throughput capacity (if using provisioned IOPS storage).
If your client application is caching the DNS data of your DB instances,
set a TTL of less than 30 seconds.
Test failover for your DB instance.

Provisioned Throughput
You specify how much provisioned throughput capacity
you need for reads and writes.
Amazon DynamoDB allocates the necessary machine
resources to meet your needs.
Read capacity unit:
Ø One strongly consistentread per second for items as large
as 4 KB.
Ø Two eventually consistentreads per second for items as
large as 4 KB.
Write capacity unit:
Ø One write per second for items as large as 1 KB.

Auto Scaling Benefits
Better Cost
Management
Better
Availability
Better Fault
Tolerance

Launch Configurations
A launch configuration is a template that an Auto
Scaling group uses to launch EC2 instances.
When you create a launch configuration, you can
specify:
Ø AMI ID
Ø Instance type
Ø Key pair
Ø Security groups
Ø Block device mapping
Ø User data

Auto Scaling Groups
Contain a collection of EC2 instances that share
similar characteristics.
Instances in an Auto Scaling group are treated as a
logical grouping for the purpose of instance scaling
and management. Auto Scaling group
Minimum size
Desired capacity
Maximum size
Scale out as needed

Dynamic Scaling
You can create a scaling policy that uses
CloudWatch alarms to determine:
Ø When your Auto Scaling group should scale out.
Ø When your Auto Scaling group should scale in.
You can use alarms to monitor:
Ø Any of the metrics that AWS services send to Amazon
CloudWatch.
Ø Your own custom metrics.
