  • This slide discusses the corresponding AWS functionality that we will support at limited public beta launch. Please note that the items under "Launch ++" are other AWS capabilities that we are currently evaluating for operability within VPC, but do not have a date as yet. Direct Internet/AWS access is our most important feature.
  • As you can recall, we’ve setup Amazon VPC in the AWS cloud. We’ve also configured a secure connection between our existing network and Amazon VPC. All of our activity inside our VPC and all traffic to and from our existing network and Amazon VPC can be monitored, managed, and secured by all of our existing security apparatus and procedures/policies.We will deploy our web server and full application platform stack on Amazon EC2 instances that are spawned within Amazon VPC.
  • Benefits of using Amazon EC2 to host your web application.
  • We will host all of our static and large files over on Amazon S3. Things like images, music, PDFs, and the like are best suited for Amazon S3. Amazon S3 provides a low-cost, highly reliable and scalable storage environment for your web applications. We will encrypt this data for security reasons.
  • You can host your relational database on top of Amazon EBS. Companies like IBM and Oracle have even enabled license portability so that you can bring your existing database licenses into the AWS cloud.
  • As you’ll recall, we want our application to be able to kickoff workflows with a bunch of systems we’re already running internally. While it may make sense, both economically and technically, to eventually migrate these systems into AWS as well, as of right now that isn’t the case. So, we’ll need to be able to have our Employee Provisioning application that is hosted in AWS be able to communicate with our internal systems. With Amazon VPC, this is easy.
  • These are some additional AWS features that we could use as part of our application.

    1. 1. Architecting Enterprise Applications in the Cloud<br />Matt Tavis<br />Solutions Architect<br />
    2. 2. What Does the Enterprise Application Demand?<br />High Availability<br />Manageability<br />Security<br />Monitoring<br />Scalability<br />Reliability<br />
    3. 3. T<br />T<br />T<br />S3 Replicas<br />EC2 Regions<br />Availability Zone A<br />Availability Zone B<br />Availability Zone C<br />Auto Scaling<br />Amazon CloudWatch<br />Elastic Load Balancing<br />Note: Conceptual drawing only. The number of Availability Zones may vary. S3 guarantees 3 or more copies across 2 or more AZs.<br />AWS has the Tools for Enterprise Demands<br />
    4. 4. Achieving Enterprise Needs is an Agreement between Architecture and Infrastructure<br />Leveraging a scalable, on-demand infrastructure requires an application that can take advantage of it.<br />Corollary: Fork-lifting a broken architecture into the AWS cloud will not make it any better<br />Architecture and Infrastructure Must Work Together<br />
    5. 5. There are Many Paths into the Cloud<br />Move to the Cloud<br />Build for the Cloud<br />
    6. 6. Design for Failure and Nothing Fails<br />Loose Coupling Sets You Free<br />Design for Dynamism<br />Security is Everywhere<br />Don’t Fear Constraints<br />Leverage a Variety of Storage Services<br />Cloud Architecture Lessons Learned<br />
    7. 7. Never expect your systems to be stable<br />Everything fails<br />Hard disks<br />Power supplies<br />Cabling<br />Network ports<br />Switches<br />Load-balancers<br />Ethernet chips<br />IO controllers<br />Fans<br />Even software fails<br />If you can add it, it can fail<br />Design for Failure and Nothing Fails<br />
    8. 8. Elastic IPs enable consistent endpoints and a re-mappable<br />Leverage multiple Amazon EC2 Availability Zones (AZs)<br />Replicate databases and persistence layers across AZs<br />Use real-time monitoring across key access points<br />Use Elastic Block Store (EBS) for persistent file systems<br />Snapshot EBS for disaster recovery and increased persistence<br />Auto Scaling and Elastic Load Balancing can automatically provision new resources<br />Use Amazon CloudWatch to monitor instance health<br />Designing for Failure with AWS<br />
    9. 9. Components should not make no assumptions about the inner workings of other components<br />Design for a jumble of black boxes<br />Loosely coupled systems and AWS<br />De-coupling systems allows for hybrid models (in-cloud + in-physical data center)<br />Balancing between clusters enables easier scaling<br />Using queues (Amazon SQS) buffers against failures<br />Loose Coupling Sets You Free<br />
    10. 10. Components should not assume the health or location of other components<br />Bootstrapping and dynamic configuration helps you scale dynamically<br />Add or build management components to enable scale-out and scale-in on-demand<br />Design for Dynamism<br />
    11. 11. With AWS, physical security is free, network security is easy, and other security can be added<br />Building secure systems with AWS<br />Create distinct Security Groups for each Amazon EC2 cluster<br />Use group-based rules for controlling access between layers<br />Restrict external access to specific IP ranges and ports<br />Use strong passwords and certificate-based authentication<br />Encrypt data stored in Amazon S3<br />Encrypt information transmitted across the wire<br />Use encrypted file systems for sensitive data<br />Security is Everywhere<br />
    12. 12. Having a flexible, on-demand pool of resources allows for different architectures that remove constraints<br />Don’t Fear Constraints<br /> I need more than xxGB of RAM per instance<br />Distribute load across multiple instances; use a shared distributed cache<br /> I need more than xxK IOPS on my database<br />Run multiple read-only copies; sharding; database clustering software<br /> My current server specs are better than the EC2 instances<br />Run more Amazon EC2 instances but only when you need them<br /> I need static IPs for my servers<br />Boot scripts that re-configure software from configuration database<br />
    13. 13. AWS offers a wide variety of storage services designed for reliability, low latency, ease of access, indexing and throughput.<br />Amazon S3 is optimized for easy access to highly durable and available storage of objects<br />Store persistent data needing durability and easy access<br />Amazon CloudFront for performance<br />Push popular objects to worldwide edge locations<br />Amazon SimpleDB for indexing, speed, scale, and simplicity<br />Store small bits of data that have no dependencies, such as metadata<br />Amazon EBS acts like a disk drive for persistent storage with high throughput and basic durability<br />Store dynamic content or a traditional RDBMS<br />Amazon EC2 local disk space for transient data<br />Leverage a Variety of Storage Services<br />
