Multitenancy Considerations

Slide 26

Slide 26 text

Design for Scalability Traditional way ● add more RAM ● use faster servers ● expensive ‘micro-optimization’ ● complex caching ● faster hard disks Cloud Applications ● minimize mutable state ● create asynchronous services ● alternative data stores ● automate deployment

Slide 27

Slide 27 text

Design for Failure "Everything fails, all the time“ Werner Vogels, CTO Amazon.com ● find single point of failures ● evaluate scenarios. What levels of risk is acceptable? ● failure tolerance

Slide 28

Slide 28 text

Minimize Mutable State Variables shared across application ● Multiple servers and processes trying to update the same variables at the same time result in deadlocks, time-outs, and failed transactions ● minimize or eliminate those in webservers, application and the database ● specific considerations for filesystems, applications and datastores ● look at cluster filesystems, object stores, NoSQL / CouchDB, MongoDB – asynchronous ‘fire & forget’ updates

Slide 29

Slide 29 text

Components & Asynchronous Services ● Offload work from main application servers – Web 2.0 ● Break tasks into separate services, run by different components ● Scale independently ● Use message queues for guaranteed delivery

PaaS offerings facilitate deployment of applications without the cost and complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities

6 © Copyright 2013 Pivotal. All rights reserved. Issues with the old way •  How do you size this environment correctly? •  How do you scale and add capacity when required? Start the whole process again? •  How do you synchronize updates to the code, database, middleware and network simultaneously? •  How do you do continuous delivery? •  Slow GTM 6-12 months •  Brittle software with hard coded dependencies. •  Hard to move code/config from DEV->UAT->PROD

Benefits of the new way •  Developers don’t have to worry about the “plumbing” •  Less dependencies in the code so applications can be moved between DEV, UAT and PROD much easier OR to other clouds •  Frequent updates means business and customers happier •  PaaS is easier to manage from an operations perspective (single distributed system rather than a collection of separate components) •  Feedback loop is quicker, code, deploy, test, fix, deploy etc.. •  Easy to scale horizontally both from an application and data point of view •  Continuous Delivery is a reality •  Allows tighter governance and policy
