Concepts
& Components Part1
What is
a Region? What is an AZ?
·
AWS is divided into geographic regions and
availability zones
·
Region
o
A Region is a geographical area. Each Region
consists of 2 (or more) Availability Zones.
§
Network connection between zones in the same
region have low latency
o
Each region is guaranteed to be completely
isolated from any other region
o
Several regions are available
§
US East—Virginia (us-east-1)
§
US West—California (us-west-1)
§
US West—Oregon (us-west-2)
§
Asia Pacific—Tokyo (ap-northeast-1)
§
Asia Pacific—Singapore (ap-southeast-1)
§
Asia Pacific—Sydney (ap-southeast-2)
§
Asia Pacific—Seoul (ap-northeast-2)
§
Asia Pacific—Mumbai Region
§
EU West—Ireland (eu-west-1)
§
EU-Central—Germany (eu-central-1)
§
South America—Sao Paulo (sa-east-1)
§
China—Beijing (cn-north-1)
§
US Government (us-gov-west-1)
·
Availability Zone (AZ)
o
An Availability Zone (AZ) is Simply a Data
Center; a group of servers
o
Individual datacenter within an AWS region. A
region is made up of multiple datacenter and the fundamental property of AWS is
building across differently availability zones and regions.
·
Two zones are guaranteed not to share any common
points of failure
·
Edge
Locations:
o
Location build to deliver cached data across the
world. CloundFront CDN utilizes this service for faster delivery to countries
without AWS regions.
Implications
of Regions and Zones
·
AWS provides the capability to deploy resources
in specific regions and availability zones
o
Pricing may depend on region
·
Can utilize a region geographically close to
users
o
To potentially improve performance
·
Can comply with legal and regulatory
requirements
o
Restrictions on where data is hosted
§
For example, within U.S. borders
·
Using multiple regions/availability zones can
reduce downtime
o
Mitigate effects of a failure of a single
location
o
Can actually improve the availability promised
by Amazon
Service
Level Agreements
·
Amazon publishes SLAs
o
The terms of the service
o
Defines Amazon’s commitment in providing the
service
§
And ramifications of not meeting the service
level
·
Different AWS services have different SLAs
·
Understanding the SLAs is critical when hosting
a solution on AWS
o
Essentially a contract between you and Amazon
·
Differences may exist between the design
specification and the SLA
o
Be sure you know what is actually being promised
What is
An Edge Location?
·
Edge Location are CDN (Content Delivery Network)
End Points for Cloud Front.
·
There are many more Edge Location than Regions.
·
There are over 50 Edge Locations.
·
Edge Location helps lower latency and improves
performance for end users.
