9. AWS Cloud allows Overcast Redundancy
Have the shadow
duplicate of your
infrastructure ready to
go when you need it…
…but only pay for what
you actually use
10. Old Barriers to HA
are now Surmountable

11. AWS Building Blocks: Two Strategies
Inherently fault- Services that are fault-tolerant
tolerant services with the right architecture

The Stack:
CW Alarms - AutoScaling
Cloudformation - Beanstalk

14. Regional Diversity
Use Regions for:

• Customers
• Data Vendors
• Staff
Compliance
Disaster Recovery
… and Fault
Tolerance!
26. Designing a HA Infrastructure
• It’s like Noah’s Ark – 2 of Everything
• Automate Scaling Quickly and Reliably
• Leverage Amazon Availability Zones
• Select Reliable Synchronization Technologies
• mySQL Replication
• Gluster
• “Trust but Verify”
27. Managed Cloud: HA Infrastructure

•Elastic IP addresses
•Varnish Cache
•Nginx for load balancing

28. If Availability is Your Lifeblood –
Consider Multi-Region Failover
• Run Your Site From at Least Two AWS Regions
• Use an Enterprise-class Database Replication
Technology – Tungsten from Continuent
• Implement a Content Distribution Network (CDN)
• Durability
• Manageability
• Security

In this video we’ll take a look at Managed Cloud – Acquia’s Drupal tuned Platform-as-a-Service.
Cloud computing is a better way to run your business. The cloud helps companies of all sizesbecome moreagile. Instead of running your applications yourself you can run them on the cloud where IT infrastructure is offered as a service like a utility. With the cloud, your company saves money: there are no up-front capital expenses as you don’t have to buy hardware for your projects. The massive scale and fast pace of innovation of the cloud drive the costs down for you. In the cloud, you pay only for what you use just like electricity.The cloud can also help your company save time and improve agility – it’s faster to get started: you can build new environments in minutes as you don’t need to wait for new servers to arrive. The elastic nature of the cloud makes it easy to scale up and down as needed. At the end of the day you have more resources left for innovation which allows you to focus on projects that can really impact your businesses like building and deploying more applications. “With the high growth nature of our business, we were looking for a cloud solution to enable us to scale fast. Think twice before buying your next server. Cloud computing is the way forward.” - Sami Lababidi, CTO, Playfish
AWS is useful for low-end traditional DR to high-end HA, but…AWS encourages a rethinking of traditional DR / HA practicesEverything in the cloud is “off-site” and (potentially) “multi-site”Using multiple sites (multiple AZs) comes largely for freeUsing multiple geographically-distributed sites (multiple Regions) is significantly cheaper and easierTends to move the default design point away from “cold” Disaster Recovery toward “hot” High AvailabilityMakes it easier to stack multiple mechanismse.g., Basic HA within one Region, DR site in second Region

Fault Separation Amazon EC2 provides customers the flexibility to place instances within multiple geographic regions as well as across multiple Availability Zones. Each Availability Zone is designed with fault separation. This means that Availability Zones are physically separated within a typical metropolitan region, on different flood plains, in seismically stable areas. In addition to discrete uninterruptable power source (UPS) and onsite backup generation facilities, they are each fed via different grids from independent utilities to further reduce single points of failure. They are all redundantly connected to multiple tier-1 transit providers. It should be noted that although traffic flowing across the private networks between Availability Zones in a single region is on AWS-controlled infrastructure, all communications between regions is across public Internet infrastructure, so appropriate encryption methods should be used to protect sensitive data. Data are not replicated between regions unless proactively done so by the customer.
Distinct physical locationsLow-latency network connections between AzsIndependent power, cooling, network, securityAlways partition app stacks across 2 or more AzsElastic Load Balance across instances in multiple AzsDon’t confuse AZ’s with Regions!
Note, the question is not “do you need to automate your deployment” or “should I use automation when I’m using the cloud?” the answer to that is YES!The question is; if you’re using fully standard PHP or Java stacks, why manage it? Beanstalk does that great, with zero lock-in. If what you need is more complex, perhaps cloudformation (note, you can do BOTH!)
