  1. 1. Amazon Web Services: Building Highly Scalable Web Applications
  2. 2. Agenda Introduction Amazon Web Services overview Amazon EC2 Amazon S3 Amazon VPC Amazon EBS Questions
  3. 3. Enterprise IT Challenges
  4. 4. Solution: Web-Scale Computing Scale capacity on demand Turn fixed costs into variable costs Always available Rock-solid reliability Simple APIs and conceptual models Cost-effective Reduced time to market Focus on product & core competencies
  5. 5. What is Cloud Computing? Whether you are running applications that share photos or support the critical operations of your business, you need rapid access to flexible and low cost IT resources. The term "Cloud Computing" refers to the on-demand delivery of IT resources via the Internet with pay-as-you-go pricing. Comparable cloud services  Amazon Web Services  Google Cloud  Microsoft Azure
  6. 6. Amazon Web Services A set of APIs and business models which give developer-level access to Amazon’s infrastructure and content. Data As a Service Amazon E-Commerce Service Amazon Historical Pricing Infrastructure As a Service Amazon Simple Queue Service Amazon Simple Storage Service Amazon Elastic Compute Cloud Search As a Service Alexa Web Information Service Alexa Top Sites Alexa Site Thumbnail Alexa Web Search Platform People As a Service Amazon Mechanical Turk
  7. 7. AWS Cloud Layers
  8. 8. Amazon Elastic Compute Cloud EC2
  9. 9. Amazon Elastic Compute Cloud (Amazon EC2) A Distributed System you can actually use! “Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.” EC2 is part of Amazon’s “pay per use” web services for software development 9
  10. 10. What can you do with EC2? Develop and run web-sites & web-services. From a personal blog all the way up to a large services like foursquare, netflix, Do large-scale data processing (Like Dr. Stiber’s GPU calculations, or the Global Warming simulation Prof. Fukuda mentioned in last lecture) Allocate & De-allocate computing resources dynamically.
  11. 11. Features : Amazon Elastic Block Store EBS-Optimized Instances Multiple Locations Elastic IP Addresses Amazon Virtual Private Cloud Amazon CloudWatch Auto Scaling Elastic Load Balancing High Performance Computing (HPC) Clusters GPU Instances AWS Marketplace VM Import/Export Enhanced Networking
  12. 12. Amazon Simple Storage Service S3
  13. 13. Amazon S3 (Amazon Simple Storage Service) Amazon S3 is storage for the Internet. Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites.
  14. 14. Amazon S3 Concepts Objects: Opaque data to be stored (1 byte … 5 Gigabytes) Authentication and access controls Buckets: Object container – any number of objects 100 buckets per account / buckets are “owned” Keys: Unique object identifier within bucket Up to 1024 bytes long Flat object storage model Standards-Based Interfaces: REST and SOAP URL-Addressability – every object has a URL
  15. 15. Functionality: Write, read, and delete objects containing from 1 byte to 5 terabytes of data each. The number of objects you can store is unlimited. Each object is stored in a bucket and retrieved via a unique, developer-assigned key.A bucket can be stored in one of several Regions. You can choose a Region to optimize for latency or address regulatory requirements. Authentication mechanisms are provided to ensure that data is kept secure from unauthorized access. Objects can be made private or public, and rights can be granted to specific users. Reliability backed with the Amazon S3 Service Level Agreement.
  16. 16. Common Use Cases: Amazon S3 can be used to support a wide variety of use cases, for example: Content Storage and Distribution Storage for Data Analysis Backup, Archiving and Disaster Recovery Static Website Hosting
  17. 17. Amazon Elastic Block Store (EBS)
  18. 18. Amazon Elastic Block Store (EBS) Amazon Elastic Block Store (EBS) provides block level storage volumes for use with Amazon EC2 instances. Amazon EBS provides highly available, highly reliable, predictable storage volumes that can be attached to a running Amazon EC2 instance and exposed as a device within the instance. Amazon EBS is particularly suited for applications that require a database, file system, or access to raw block level storage.
  19. 19. Features: Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can be mounted as devices by Amazon EC2 instances. Storage volumes behave like raw, unformatted block devices, with user supplied device names and a block device interface. Amazon EBS volumes are placed in a specific Availability Zone, and can then be attached to instances also in that same Availability Zone. AWS also enables you to create new volumes from AWS hosted public data sets. Amazon EBS also provides the ability to create point-in-time snapshots of volumes, which are persisted to Amazon S3. These snapshots can be used as the starting point for new Amazon EBS volumes, and protect data for long-term durability.
  20. 20. Amazon Virtual Private Cloud (Amazon VPC)
  21. 21. Amazon VPC Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the Amazon Web Services (AWS) Cloud where you can launch AWS resources in a virtual network that you define. You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your webservers that has access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access.
  22. 22. Continue… You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. Additionally, you can create a Hardware Virtual Private Network (VPN) connection between your corporate datacenter and your VPC and leverage the AWS cloud as an extension of your corporate datacenter.
  23. 23. VPC… Features and Benefits: Multiple Connectivity Options Secure Simple All the Scalability and Reliability of AWS Use cases: Host a simple, public-facing website Host multi-tier web applications Host scalable web applications in the AWS cloud that are connected to your datacenter Extend your corporate network into the cloud Disaster Recovery
