Private and hybrid clouds can provide benefits like increased security, lower latency, and cost savings over the long term compared to public clouds. Key considerations for implementing a private or hybrid cloud include hardware requirements, choosing cloud infrastructure software, high availability design, capacity planning, monitoring, access controls, and separating management from infrastructure. It is important to understand workload needs and have a plan for implementation, management, and maintenance of the cloud.

- 5. #5 #rightscale Terminology Virtualization • Division of one physical server into multiple isolated virtual environments Public Cloud • Hosted by cloud provider • On-demand, pay-as-you-go, accessible via API Private Cloud • Typically single-tenant • Hosted on-premises or co-lo facility Hybrid Cloud • Spans more than one private or public clouds • Extending the definition to include private virtualized environments
- 6. #6 #rightscale Infrastructure Evolution Old School Data Center Virtualization Early days Early “Cloudification” Sophistication and Sex appeal 20th century 2000 2006 Present day
- 7. #rightscale State of the Cloud Report
- 8. #8 #rightscale RightScale State of the Cloud Report 2013 • 625 respondents from various industry segments • Equal representation from large enterprises and SMBs Complete report available at http://www.rightscale.com/lp/state-of-the-cloud-report.php Source: April 2013 RightScale State of the Cloud Report
- 9. #rightscale Why Do You Need Private or Hybrid Cloud?
- 10. #10 #rightscale Why would you build a private cloud? • Workload and infrastructure interaction • Security / Regulation / Compliance • Latency • User experience • Cost over a longer time horizon And of course, agility…
- 11. #11 #rightscale Build with an end in mind
- 12. #12 #rightscale When would you need a hybrid or multi-cloud? • What if your application outgrows the private cloud? • Common desire is for “cloud-bursting” • Regulation / Compliance for parts of the application • Most common: • Multiple clouds used by different parts of the same organization for different applications, with each app in one cloud
- 14. #14 #rightscale Use Case: Untested Workloads • Scalable applications with uncertain demand • Public cloud used as “proving ground” for new applications • If applications fail, they are allowed to run their course in the public cloud until they are end-of-lifed • If an application gains traction, it remains in the public cloud during its growth phase • When stability of workload is reached, the application is transitioned into the private cloud
- 15. #15 #rightscale Use Case: Hybrid Cloud Bursting PRIVATE CLOUD PUBLIC OR PRIVATE CLOUD LOAD BALANCERS APP SERVERS MASTER DATABASE SLAVE DATABASE OBJECT STORAGE APP SERVERS PUBLIC INTERNET Cloud Bursting
- 16. #16 #rightscale Use Case: HA / DR using Hybrid Cloud (Demo) • Production environment in one cloud • DR environment in a second cloud • Most common configuration is the “Warm DR” scenario • Replicating slave in a second cloud • All other servers in non-operational state • Failure of production environment requires promotion of slave to master, launching of “standby” servers, and DNS reassignment
- 17. #17 #rightscale Use Cases: IT Vending Machine (Demo) • Users select one of several preconfigured tech stacks • Isolated dev/test environments
- 18. #18 #rightscale RackConnect, Direct Connect, Hybrid for Metro Area • Rackspace uses RackConnect between RAX dedicated hosting private cloud and RAX public cloud • Amazon uses Direct Connect between private clouds and AWS AZs • Both offer low-latency, secure connectivity • The catch is – your private cloud needs to be “near” the public cloud
- 20. #20 #rightscale Hardware Considerations • Compute • Commodity • Allows for easy addition of capacity • Easy swap-out of failed components • High end/specialized • May be required for intended workloads • Limits available options • Increases costs • Complicates maintenance • Networking • Driven by topology, latency demands, and price • Some cloud infrastructure software offerings have support for network hardware devices (load balancers in particular) • Storage • Cost vs. Performance (commodity? SSD?, etc.)
- 21. #21 #rightscale Software Considerations • Cloud Infrastructure Software • CloudStack, OpenStack (Rackspace Private) etc. • Open source with commercial support • Access to resources • Web interface • API • Documentation • Industry talent pool • Hypervisor • Baremetal
- 22. #22 #rightscale Finding a home for your cloud Various options, although, trade-offs with each decision • On-premises • You are responsible for facility, power, network, operations • You get full access, physical security, secure access for your internal users • Co-location facility • Co-lo provider takes the headache of operations and physical aspects • You would need to have managed service to go with co-lo, to make it practical • Hosting facility adjacent to a public cloud
- 24. #24 #rightscale Implementation Process • Design • Know the workload / performance requirements • Keep HA in mind • Capacity Planning • Monitor and Automate • Access Control • Manage • Test (and test again)
- 25. #25 #rightscale Design: High-availability options No HA or Redundancy HA Configuration Simple Complex
- 26. #26 #rightscale OpenStack Infrastructure HA (example) Several single points of failure in OpenStack deployment • OpenStack API services • MySQL • RabbitMQ Solved in various ways • Pacemaker cluster management • Keepalived (e.g: RAX Private Cloud) • MySQL (Galera), RabbitMQ (active-active mirrored queues) Eliminate SPoFs as best as you can.
- 27. #27 #rightscale Design: Network Options • OpenStack • FlatDHCP – Typical for single tenant • VLAN manager – Typical for multi-tenant env • CloudStack • Basic Zone – Typical for single tenant • Advanced Zone – Typical for multi-tenant env
- 28. #28 #rightscale Design: Capacity Planning – it’s simple! • Don’t have a blank check backed by limitless funds or perfectly clear expectations from your user that never change? Well, you need capacity planning! • Capacity planning is also budget planning and is directly related to SLA you offer • Know your workload, determine the difference between spike and trend • Monitor, tweak capacity, rinse, repeat … • Check out http://www.planforcloud.com
- 29. #29 #rightscale Monitor and Automate • Understand your workload • Number of VMs requested • Allocated CPU, Memory, Disk capacity • Actual utilization of resources • Monitor using tools like Gaglia + Nagios • Hypervisor hosts • VM containers • Resources consumed by the app • Automate • Chef, Puppet, Fuel etc..
- 30. #30 #rightscale Access Control and Tenant Management • Each cloud platform is slightly different but follows similar principles • Most clouds have option of integrating with existing authentication and authorization system
- 31. #31 #rightscale Separate Management Layer from Infrastructure • Keep the keys to the car outside the car
- 32. #32 #rightscale Separate Management Layer from Infrastructure • Connect your private / hybrid cloud to RightScale • Abstracts underlying details of the cloud infrastructure offerings • Presents consistent interface to the available resources regardless of the underlying infrastructure provider • Provides a cloud-portable solution • Provides orchestration tools for provisioning and management
- 33. #33 #rightscale Always keep the application in mind!
- 34. #34 #rightscale Summary/Conclusions • Private (and therefore hybrid) clouds were originally thought of as an academic exercise or science project • Recent advances (particularly in cloud infrastructure software) have shown private and hybrid clouds to be viable IT delivery models • Many considerations come into play • Design • Hardware • Software • Implementation Details • No “one size fits all” • Do your research.

- Workload and Infrastructure InteractionApplications have different resource needsChoose the right fit for your application and your infrastructureSecurityData may be contained within the private cloud, thus allowing for stricter security complianceLatencyConsumers of the private cloud resources are generally “closer” to the private cloud, which reduces latencyUser ExperienceRelated to latency, end user experience is enhanced due to proximity to resources.CostOPEX is generally reduced. (CAPEX is another story )
- When private cloud resources are exhausted, a server tier expands into the public cloud to tap into the “infinite” resourcesConsiderations:Security – public Internet is traversedLatency – traversal of public Internet involves the Great UnknownCost – bandwidth charges for public Internet traversalComplexity – setting up a secure environment is not a trivial taskWe will explore use-cases for hybrid cloud

- Hardware ProcurementPre-existing or new?Pre-existing limits ability to tailor infrastructure to workloadsCloud Infrastructure SoftwareThis decision will dictate/limit many future decisionsResearch options, and choose wisely!Cloud TopologyZones, regions, storage allocation, HA considerations, etc.Build or BuyUse in-house resources if expertise existsThird-party resourcesBuild using existing resourcesBuild using new preconfigured hardwareDesign – Design for HA, use uniform hypervisor, Network is a key consideration – switching from basic zone or FlatDHCP to advanced zone or quantum isn’t that simple.. Make use of hypervisors uniformly..Compute density is key factor in capacot planning.. You will need to incorporate physical CPU cores, RAM, oversubscription ration and instance storage.. Storage options, object storage, block storageScalability and HA of the cloud itself – controller nodes, api end point redundancy, Automate – crowbar, chef, puppet, fuel etcMonitoring – Is usually an after thought but it shouldn’t be.. It is important to establish so,etrendig so that you can forecast capacity and plan accordingly

- Monitor how your app is using the cloud and automate..Spare capacity or cloud bursting.Automation plan – if a host goes down, it needs to get up..
- This is around configuring the cloud itself.. Separating tenant, dividing resources, projects..
