AWS Global Infrastructure

23 Geographical Regions, 73 Availability Zones, 216 POPs

* Available to select AWS customers who request access. Customers wishing to use the Asia Pacific (Osaka) Local Region should speak with their sales representative.

North America• 6 Regions

• 25 Availability Zones

• 44 Edge Network locations

• 2 Regional Edge Cache locations

Europe / Middle East / Africa• 7 Regions



• 2 Regional Edge Cache locations.

Asia Pacific• 6 Regions


• 1 Local Region

AWS Regions are comprised of multiple AZs for high availability, high scalability, and

high fault tolerance. Applications and data are replicated in real time and consistent

in the different AZs

AWS Region Design

AWS Availability Zone (AZ)

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.

Common Questions For

RDS SQL Server


Monitoring Options

Amazon CloudWatch metrics & alarms

Upload DB logs directly to CloudWatch Logs

Enhanced Monitoring for Amazon RDS

• Access to over 50 CPU, memory, file system, and disk I/O metrics

• As low as 1-second intervals

Integration with third-party monitoring tools

How do I monitor my Amazon RDS database?


DB load

• Average active sessions

Identifies database bottlenecks

• Easy

• Powerful

• Top SQL/most intensive queries

Identifies source of bottlenecks

Enables problem discovery

Adjustable timeframe

• Hour, day, week, and longer

Introducing Amazon RDS Performance Insights

How do I improve database performance?


RDS uses Simple Notification service (SNS) to receive

notification when an event occurs

Notifications can be:

• Email, text message, or call to an HTTP endpoint

Six different source types:

• DB instance, DB parameter group, DB security group, DB snapshot, DB

cluster, DB cluster snapshot

17 different event categories:

• Availability, backup, deletion, configuration change, etc.

How do I know when service events happen?

Generates Amazon CloudWatch Events when it detects a problem, so that you can be notified.

• Provides a summary of what’s really happening with the application.

• You get an overview of the type of problem, severity, probable source of the problem, and additional insights with potential next steps.

• Identifies database bottlenecks

Introducing Amazon Application Insights for .NET and SQL Server

In the example on the left, the SQL Server transaction

log was full due to a missing or broken back up.

• To remediate this issue, you run a SQL Server

backup using AWS Systems Manager Automation.
