RightScale Webinar: December 8, 2010 – In this Webinar, we discuss the benefits and pain points of multi-cloud as well as key considerations to have in mind when going multi-cloud. We present examples of multi-cloud scenarios and describe the design principles to consider when architecting deployments that must span and migrate across different clouds and providers.

  • Betsy, transition to Ed
  • So here’s a graphical representation of existing clouds
  • So here’s a graphical representation of existing clouds
  • So…this sounds like a pretty onerous goal…quite a challenging…so how do we approach such a thing? What is different from working in single-cloud mode?
  • The punchline here is that one needs to step back, and look at the challenges a bit like an integration problem. That is, one needs to work with “portable abstractions” and be able to integrate them across.I think it is very similar to what one would do in building an application or service, consisting of several sub-applications written in different languages.So let me share some considerations to be had in mind when going multi-cloud [POINTS]So it is a fairly different way to think about stuff…it’s all about higher-level abstractions.But not all is lost, RightScale helps with these a lot….let me tell you how…
  • RightScale already provides several abstractions that are cloud-agnostic. In fact you’re already using probably all of them (despite you might only be deployed in 1 cloud)..We have the concept of a server (something that can be launched/running on any cloud)The concept of a ServerTemplate, which specifies the configuration we want on a serverAnd the concept of an MCI which specifies which image configuration we want (lower-level stuff)And all these things are RS concepts…the cloud is not really involved in all this…
  • Right not we focus on the ability to migrate applications…the next steps will be to run concurrentlyWE use some of these techniques…but are not packaged …let me finish with a multi-cloud deployment use case that can be realized today. We and others are using. Note it’s not about the more future looking scenario of having you production app runnig simultaneously in multiple clouds….it’s about being able to migration applications/deployments from cloud to cloud, much like in a cookie cutter type of way…

    • 5. What do we mean by cloud?
      A cloud is a physical data center entity behind an API endpoint
      What do you mean by that?
      Amazon Web Services is not a cloud
      EC2 is not a cloud
      Eucalyptus, are not a cloud
      EC2 East, EC2 AsiaPacific, my private cloud… are clouds
      An availability zone is not a cloud, it’s part of one
      Think of a cloud as a “resource pool” accessed via API
    • 6. Where is my cloud in the wild?
    • 7. Where is my cloud in the wild?
      There might be just a few big cloud players
      …but there will be a myriad of clouds
    • 8. Where are my clouds in RightScale?
      Dashboard example:
      AWS, Rackspace and several private clouds in one account
      A cloud is first registered with RightScale
      Once a cloud is registered, a user can start using it
    • 9. What does multi-cloud mean?
      It’s about deploying your application:
      Across different clouds
      Spanning cloud providers (most likely with different API’s)
      Utilizing private and public ones
      It’s about evolving your application to:
      Incorporate new clouds as they appear
      Or quickly moving servers to utilize leftover or new cloud capacity
      All seamlessly:
      Without having to learn a new interface every time
      Working together in an integrated manner
      It’s about using multiple cloud providers, not choosing one
      Current focus: cloud portability
    • 10. Multi-cloud: benefits
      Redundancyfor disaster recovery and business continuity
      Geo-location for latency and/or policy compliance
      Leverage unique cloud-specific services when needed
      Leverage public cloud cost benefits (cheaper and/or infinite)
      Leverage existing data centers: private cloud
      Move services with bursty, unpredictable apps to public cloud
      Private cloud for apps with regulatory compliance reqs
      Support varying levels of security concerns
    • 11. Multi-cloud: pain points
      APIs differ
      Different sets of resources
      Different formats and encodings
      Several simultaneous versions for a single cloud
      Abstractions differ
      Network architectures differ: VLANs, security groups, NAT, IPs, ACLs, …
      Storage architectures differ: local/attachable disks, backup, snapshots, …
      Hypervisors and machine images differ
      Supported features differ
      …cost models, billing, reporting…etc
      They are truly different applications, with different semantics
    • 12. How to think multi-cloud?
      “Akin to designing your application using several programming languages”
      Deploy using cloud-specifics, design using generic concepts
      Have tools that translate your concepts to cloud-specific ones.
      Design for geographic dispersion
      Think of how to share data across
      Know if you’re designing for HA or simply for portability
    • 13. How does RightScale help?
      Unified Multi-Cloud UI and new API (in progress)
      Multi-Cloud Servers/Arrays
      Multi-Cloud Server Templates
      Multi-Cloud Images
      Others in the pipeline
      runnable abstraction
      software config
      runtime config
      cloud resources
    • 14. (Multi-Cloud) Servers and Arrays
      Servers and Arrays are runtime abstractions
      All Servers look and smell similar, regardless of cloud:
      Can be started, stopped or run operational actions in the same way
      Show monitoring data, and can configure alerts in the same way
      They coexist in mixed deployment listings, same filters, columns…
      They can support abstractions that some clouds don’t support

      Can be very different beasts, but they are seamlessly integrated
      runnable abstraction
      software config
      runtime config
      cloud resources
    • 15. Parenthesis: What are ServerTemplates?
      Configuring servers
      through bundling Images:
      Configuring servers
      with ServerTemplates:
      Custom MySQL 5.0.24 (CentOS 5.2)
      Custom MySQL 5.0.24 (CentOS 5.4)
      A set of configuration directives that will install and configure software on top of the base image
      MySQL 5.0.36 (CentOS 5.4)
      MySQL 5.0.36 (Ubuntu 8.10)
      MySQL 5.0.36 (Ubuntu 8.10) 64bit
      Frontend Apache 1.3 (Ubuntu 8.10)
      Frontend Apache 2.0 (Ubuntu 9.10) - patched
      CMS v1.0 (CentOS 5.4)
      CMS v1.1 (CentOS 5.4)
      My ASP appserver (windows 2008)
      My (windows 2008) – security update 1
      Base Image
      Very few and basic
      My (windows 2008) – security update 8
      SharePoint v4 (windows 2003) – 32bit
      SharePoint v4 (windows 2003) –64bit
      Win 2003
      CentOS 5.2
      Ubuntu 8.10
      SharePoint v4.5 (windows 2003) –64bit
      CentOS 5.4
      Win 2007
      Ubuntu 9.10

    • 16. Parenthesis: What are ServerTemplates?
      Anatomy of a
      Server Template
      Example Server Template:
      MySQL 5.0
      RightScript/Recipe 6
      Initialize slave

      RightScript/Recipe 6
      Perform backup
      RightScript/Recipe N
      Start all services

      RightScript/Recipe 5
      Setup DNS and IPs
      RightScript/Recipe 4
      Restore last backup
      boot sequence
      boot sequence
      RightScript/Recipe 3
      Configure/tune MySQL
      RightScript/Recipe 2
      Install MySQL Server
      RightScript/Recipe 1
      Install monitoring
      Base Image
      Right Image
    • 17. (Multi-Cloud) Server Templates
      They are software configuration abstractions
      Bridge the gap between the starting point (a base Image) and a fully configured machine
      Abstract Cloud and Operating System differences
      Gather a set of user defined, high-level Input values
      Can partially help in the sharing of data
      Are versionable and publishable
      Allow configuring servers always in the same or equivalent way
      runnable abstraction
      software config
      runtime config
      cloud resources
    • 18. Multi-Cloud Images (MCI)
      MCI’s abstract a set of requirements in a cloud image
      Example: A CentOS 5.4 Image
      Provide an equivalency map of base images across clouds
      CentOS 5.4 Image is ‘ami-feff’ in EC2 East, and ‘1234’ in Rackspace
      They are versionable and publishable
      Are associated to ServerTemplates
      runnable abstraction
      software config
      runtime config
      cloud resources
    • 19. Multi-Cloud Images: RightImages
      RightScale maintains such maps (MCI’s) for all public clouds
    • 20. Data locality and mobility
      A topic a bit further down the road
      A big hurdle to overcome: clouds are isolated
      How can our app share data across its clouds then?
      External globally accessible services.
      Transferring data snapshots across.
      Maintaining online data replication across clouds.
      Using an inherently replicated service, that is distributed.
      Keeping track of your moving data
      Where’s the latest? What’s my lineage? how do I manage my datasets?...
      We’re thinking about useful multi-cloud abstractions to help with all that
    • 21. Multi-Cloud Use Case: portability
      Test & dev
      US customers(production)
      EU customers(production)

      US customers(beta)
    • 22. Multi-Cloud Use Case: portability
      Scalable, powerful
      and redundant
      Test & dev
      US customers(production)
      EU customers(production)

      Load balancer
      and recipes
      US customers(beta)
      App Server
      CentOS 5.4
      Less power
      and redundancy
    • 23. Multi-Cloud Use Case: Demo
      Live Demo
    • 24. Thinking multi-cloud: summary
      Work with generic abstractions (deploy using cloud-specifics)
      Take advantage of each specific cloud’s strengths
      Avoid lock in.
      Use or build generic templates:
      support multiple OSes, and cloud types (not just clouds)
      Keep a good and clean mapping of Images
      Maintain just a few and use them across your server templates
      Know your data:
      Where is it, and what access patterns you’re using
      Keep track of where it is, and how it moves.
      Start with portability, then move to HA-distributed setups
      Think different, again!

    • 27. Using these abstractions: Server
      • A Server has a ServerTemplate
    • Using the abstractions: ServerTemplate
      • A ServerTemplate has a list of suportedMCIs
    • Using these abstractions: MCI’s
      • Each MCI will have mappings to several clouds
