  1. 1. High Availability and Disaster Recovery
  2. 2. Outline 1. High Availability/DR Requirements 2. Cloud Environment for High Availability and DR 3. High Availability/DR Cloud Deployment Options 4. Basic Cloud Deployment Architecture 5. Intermediate Cloud Deployment Architecture 6. Advanced Cloud Deployment Architecture 7. Ultimate Cloud Deployment Architecture 8. High Availability/DR Challenges Akelios © 2010 2
  3. 3. 1. High Availability/DR Requirements High Availability/DR Requirements • High Availability and Disaster Recovery (DR) requirements often overlap • Application and Infrastructure Scalability • New Software Version Deployment • Transparent, Real-Time or Near Real Time Failover • Uptime Requirements • Disaster Recovery • Application and Data Rollback Akelios © 2010 3
  4. 4. 3. Cloud Environment for High Availability and DR Cloud Environment High Availability and DR Attributes • Unlimited Resources • Ability to Allocate Resources on Demand • Ability to Clone Environments • Ability to Allocate Resources Automatically • Geographical Dispersion • Ability to Create Environments on Demand Akelios © 2010 4
  5. 5. 4. High Availability/DR Cloud Deployment Options High Availability/DR Cloud Options • High Availability and DR recommendations and options vary in accordance with the uptime, scalability and cost requirements Akelios © 2010 5
  6. 6. 5. Basic Cloud Deployment Architecture The Basic Cloud Deployment Option • Application infrastructure (Web Servers, Applications Servers, Databases) is set up in a single Cloud Zone • In case of a catastrophic failure, the entire environment is restored from the back-up “image” and “storage” in a different Cloud Zone • In takes roughly an hour for “A” record propagation and back-up loading • Uptime is governed by Cloud Provider Zone availability • A Basic Cloud Deployment option scales with an addition of resources to the Cloud Zone Akelios © 2010 6
  7. 7. 5. Basic Cloud Deployment Architecture The Basic Cloud Deployment Option Scheme Akelios © 2010 7
  8. 8. 6. Intermediate Cloud Deployment Architecture The Intermediate Cloud Deployment Option • Application infrastructure (Web Servers, Applications Servers, Databases) is set up in a multiple Cloud Zones • Second Cloud Zone is a scaled down copy of the main Cloud Zone • In case of a catastrophic failure, the unaffected Cloud zone takes over • It takes roughly 30 minutes to add resources to the scaled down Cloud Zone to restore full availability • Uptime is governed by Cloud Provider Multi-Zone availability Akelios © 2010 8
  9. 9. 6. Intermediate Cloud Deployment Architecture The Intermediate Cloud Deployment Option Scheme Akelios © 2010 9
  10. 10. 7. Advanced Cloud Deployment Architecture The Advanced Cloud Deployment Option • Application infrastructure (Web Servers, Applications Servers, Databases) is set up in a multiple Cloud Zones • Second Cloud Zone is a full copy of the main Cloud Zone • In case of a catastrophic failure, the unaffected zone takes over • The Advanced Cloud Deployment option has virtually no downtime, unless both Cloud zones are affected • Uptime is governed by Cloud Provider Multi-Zone availability • This option is expensive since it requires full Cloud zone duplication Akelios © 2010 10
  11. 11. 7. Advanced Cloud Deployment Architecture The Advanced Cloud Deployment Option Scheme Akelios © 2010 11
  12. 12. 8. Ultimate Cloud Deployment Architecture The Ultimate Cloud Deployment Option • Application infrastructure (Web Servers, Applications Servers, Databases) is set up in a multiple Cloud Providers • Second Cloud Provider is a full replica of the main Provider • In case of a catastrophic failure, the unaffected Cloud Provider takes over • The Advanced Cloud Deployment option has virtually no downtime, unless both Cloud Providers are affected • This option is the most expensive one, since it requires full duplication for using multiple Cloud Providers Akelios © 2010 12
  13. 13. 8. Ultimate Cloud Deployment Architecture The Ultimate Cloud Deployment Option Scheme Akelios © 2010 13
  14. 14. High Availability/DR Challenges High Availability/DR Challenges • Overall application is designed for the named resources • Application Service Layer is not designed for clustering • Application DB Layer is designed for a single database • Application Database is not designed for replication • Application Caching Strategy is designed for long data “hoarding” Akelios helps you overcome these challenges on your way to implementing effective High Availability and DR strategies Akelios © 2010 14
