High Availability Internet Hosting

The importance of your Internet presense is very likely to increase, not decrease. For companies like ASPs and many others your internet presense is your existence.

Thus was born High Availability Hosting. OTC's multiple data centers, private network, industrial yet flexible architecture are ideal for delivering High Availability Hosting environments..

• What is High Availability?

  • Infrastructure is inherently designed to be available to some degree at all times

    
    

  • Analyze scalability, reliability and security throughout a framework such as OTC's Internet Delivery Stack

    
    

  • Redundant hardware improves recovery time but is not by itself is not high availability

    
    

  • Typical tactics for high availability are:

    
    

    • Isolate geographies  - data centers in different weather systems

      
      

    •  pool resources -  cluster servers other devices

      
      

    • avoid over subscription - acquire and manage properly

      
      

  • Well designed, highly available architecture is often also very scalable

    
    

  • Generally requires complex replication and integration at the application and database layers 

    
    

• Isolate Geographics

  • Using multiple data centers in different weather systems you can isolate your servers (and your customers) from wide spread outages

    
    

  • Requires high-speed network between data centers to enable rapid repliation of data

    
    

  • Often requires modification to application and database code

    
    

• Pool Resources

  • Cluster common resources, such as servers or bandwidth, so it appears like a single, large "pool".  Provides redundancy

    
    

  • If one component of the pool fails it the remainder take up the slace. Operate the pool at a utilization that allows for typical failure rates

    
    

  • Use a framework such as OTC's Internet Delivery Stack to cost effecitvely pool bottleneck resources

    
    

• Avoid Over Subscription

  • Undersized resources such as compute, storage or bandwidth will bottleneck even the most elegant architecture

    
    

  • Contracted for more than you need to satisfy your expected utilization. It's not worth losing customers over lack of performance

    
    

  • Manage resources such as bandwidth to make sure you have enough before you need it
