Messaging: Harnessing The Cloud


Published on

The term ‘Cloud’ is used extensively in technology circles, meaning different things to different people. But what does the ‘Cloud’ mean for email?
Andrew and Nigel, discuss the opportunities and dangers presented by ‘Cloud’ computing. Where can the ‘Cloud’ add value to our business, and reduce spiralling costs? Are there cases when handing over your data / messaging services isn’t such a good idea? How can we pick and choose the best bits of the ‘Cloud’ whilst retaining control? And what is the ‘Cloud’, really…?

Messaging: Harnessing The Cloud

  1. 1. Messaging: Harnessing the Cloud Andrew Quinn & Nigel Robson 15/11/2013
  2. 2. What is the Cloud? Flexibility Public Cloud Scalability Abstraction Software as a Service (SaaS)? Infrastructure as a Service (IaaS)? Platform as a Service (PaaS)? Hosting? (I care about the outcome, but not the details) Private Cloud Partner Cloud
  3. 3. Private Cloud
  4. 4. What is a Private Cloud? Private Cloud? Cupboard Server Room Data Centre
  5. 5. Typical Example
  6. 6. Private Cloud
  7. 7. Public Cloud
  8. 8. Public Cloud (Email) • You pay for the number of mailboxes you need • Can scale up… • … or down • Implementation detail is abstracted away
  9. 9. Emergence of “The Cloud” • It’s not new! • The buzzword is new... • People have been using the “cloud” for years – Personal email – Websites – Blogs, etc.
  10. 10. Emergence of “The Cloud” • Several technological advances have made remote hosting applicable to a wider set of services: – – – – Virtualisation Automation Self-Service Internet Speeds • Along with this growth of service offerings comes an exciting new buzzword to help sell them: “The Cloud”
  11. 11. What can the Cloud do for Email? • • • • Hosted Mailboxes Hosted Hygiene (anti-virus, anti-spam) Hosted Archiving Service Continuity
  12. 12. Pros, Cons & Considerations
  13. 13. Uptime Resiliency often comes as standard with large-scale hosting Uptime is not necessarily guaranteed Do SLAs consider disruption, or just fullscale outages? 99.9% uptime SLA Approx. 45mins outage per month
  14. 14. Support Don’t need your own in-house specialist Support is often 24/7 Support may be difficult to get hold of if there is a problem
  15. 15. Recovery No backup hardware to worry about No daily checks to worry about Granular recovery is usually not an option Options are limited in non-disaster scenarios such as accidental deletions
  16. 16. Flexibility Can easily scale up without lead time Can scale down to save cost Costs can scale up quite quickly too! Consider an internal approval process for cloud resources
  17. 17. Security Outsource a lot of the complexity Less need to keep on top of upcoming threats Where is your data? Who can access your data? Is your data mined? Is your provider on top of upcoming threats? May violate regulatory requirements
  18. 18. Infrastructure No hardware required No maintenance to worry about Requirement for physical space, power, cooling, electricity reduced Completely reliant on internet connectivity Bandwidth may be an issue depending on location
  19. 19. Performance Cloud infrastructure is built to scale You don’t know what you’re getting Some vendors cut corners to reduce costs Consider asking for a free trial
  20. 20. Updates No costly periodic system upgrades Time and license costs Always licensed for the latest and greatest Updates likely to be forced on you May have to update on premise systems / clients more frequently User training is still necessary!
  21. 21. Integration May have integration with other cloud features (e.g. Office 365, Google Apps) Limited customisation Limited scope for 3rd party extensions May not integrate with business systems
  22. 22. Costs Little up-front investment required to get up and running No unexpected hardware costs Recurring cost Can be more expensive in the long run
  23. 23. Hybrid Deployment
  24. 24. Hybrid Deployment • • • • Mix and match for the best of both worlds Cloud flexibility and scalability On premise control and integration Appears as a single Exchange organisation • Federated identity / single sign on
  25. 25. Hybrid Deployment • Mailboxes can be hosted locally… • …or in the cloud • Mailboxes can be moved to and from the cloud • Or archived to the cloud
  26. 26. Hybrid Scenarios • Permanent / Temporary – Permanent staff on premises – Temporary staff in the cloud • Regulatory – Regulated mailboxes on premises – Unregulated mailboxes in the cloud • Burstable Capacity – Quickly expand using the cloud – Move on premises after extending physical capacity
  27. 27. Partner Cloud
  28. 28. Partner Cloud • Similar to a public cloud, but implemented by a 3rd party • May offer a more customised service • May provide professional services to help with migration
  29. 29. The Waterstons Approach
  30. 30. The Waterstons Approach • We don’t do high volume, commodity “cloud” hosting – Microsoft and Google have that pretty well covered – We help customers to plan for and migrate to these platforms, where appropriate • We provide a bespoke solution unique to the specific needs of an organisation • We can mix and match vendors and applications to provide the best solution
  31. 31. The Waterstons Approach • A fully transparent service – You can see the physical infrastructure – You have full access to your servers • Provides the scalability of a cloud solution • Allows the customer to retain control
  32. 32. The Waterstons Approach: Real World Example
  33. 33. The Waterstons Approach: Real World Example On Premise Benefits • Retain Exchange 2010 to support existing legacy applications • Implementation of Enterprise Vault archiving solution • Full access to servers • Integration with business systems Cloud Benefits • Flexibility to scale up as acquisitions are made and demand increases • Monthly costing model • Not reliant on a physical office location
  34. 34. Summary • • • • Flexibility and scalability Rapid service provisioning Can be restrictive Consider security and regulatory requirements • Not all clouds are equal • The cloud isn’t for everyone
