In this session, explore three benefits of private, dedicated network connections to AWS. Learn how you can transport business-critical data directly from your data center, office, or colocation environment into and from AWS over dedicated network connections. Discover how to dynamically scale your bandwidth up to 300 percent, only paying for what you use, and how to use dynamic scaling to speed up backups, temporary or scheduled workloads, moving from test to live production, and new product launches. Also, learn how to use private network connectivity to help build hybrid environments in situations where security and compliance are critical. Hybrid environments let you extend your private on-premises infrastructure with the elasticity and economic benefits of AWS.  Session sponsored by Level 3.

7. AWS Direct Connect - high performance connectivity
• A trusted path for enterprises to migrate and optimize applications in the
cloud
• Seamless, private connectivity for private, public, and hybrid IT
environments
• The scalability, efficiency, and flexibility of the public cloud without
compromising performance, productivity, or revenue

8. Real-time data feeds
Level 3 Cloud Connect Solutions AWS Direct Connect
AWS
CHALLENGE
Video, voice, and collaboration applications require low latency and consistent network performance.
SOLUTION
Enable direct user access from customer premises directly to AWS. Single hop routing removes variable latencies, packet
loss, and the unpredictability of the Internet.

12. Variable workloads – Brock White case study
Level 3 Cloud Connect SolutionsAWS Direct Connect
AWS Enterprise IT Environment
CHALLENGE
Back-ups can time out with large data sets that require multiple hours to execute
SOLUTION – Scheduled Bandwidth
The Dynamic Capacity capabilities allow the firm to immediately double or triple its network capacity when network traffic
increases for weekly back-ups.
“The automatic threshold
capability made Dynamic
Capacity twice as useful for us.
You tell it what you need and it
automatically does it for you. The
important point is that with
flexible bandwidth my time is
freed up to work on other
business solutions and not
infrastructure. I don’t have to
worry about my network, or even
think about its performance.”

21. Design principles
• Network isolation
• Use internal ELBs for traffic between
tiers
• Hub-and-spoke model for shared
services
• Account-level isolation where prudent
• Turn on and enforce AWS CloudTrail
and AWS Config
• Subnets/route tables/NACLs/SecGrps
are cheap (free)
• Only downside risk is complexity
• Architecture Best Practices

BEST PRACTICES:
Create encrypted Amazon EBS
volumes to store the most sensitive
data
Use Amazon S3 bucket policies to
force use of server-side encryption
Use Puppet to configure applications
to use encrypted storage for sensitive
data
Force SSL ciphers and encryption
standards across all web hosts
