Descrição: Quando o seu crescimento ou a demanda por seus sistemas excederem, ou se prevê que excedam, sua capacidade atual - esse é um "bom" problema.  No entanto, isso pode ser tanto uma ameaça à confiabilidade do seu sistema quanto qualquer outro fator. Nesta sessão, mergulhe nos conceitos básicos de planejamento de capacidade e estimativa de custos, incluindo as ferramentas que o Azure fornece para ajudar com ambos. Terminamos com uma discussão e demonstração de como os Traders Tailwind aplicaram criteriosamente os recursos de dimensionamento do Azure.  Aprenda como satisfazer seus clientes e uma demanda crescente, mesmo quando "desafiado" pelo sucesso.

14. When may we need to scale?
Sometimes we
can plan for scale
Sometimes we’re
hit by surprise
Hopefully, the system
just takes care of it

15. A quick primer

16. Some pre-requisites
Scaling up Scaling out
Manually scaling Auto-scaling
DIY scale Inherent scale

35. The cloud
has limits too
The cloud offers a whole new
level of scale. However, there are
some limits to know about.

38. Keep an eye
on the cost
Adding more servers
makes you more scalable
But it can cost more, too

39. Cost management

40. Scaling Tailwind Traders

41. Perform
regular
architecture
reviews
Keeping on top of things
once deployed, will ensure
you’re always ready for scale
aka.ms/OPS50architecture

42. Scaling vs.
finding the bugs
Do we always need to scale?
Or is there a bug?

43. You work closely with developers
to make your systems more scalable

47. Why use scale sets?
Autoscaling
Leverage Availability Zones
Automatically create and integrate with load balancers

48. Some considerations
Avoid instance stickiness
Remove persistent data
Design for scale-in

49. Scaling our products service: decoupling

50. Scaling with queues

51. Scaling our products service: caching

55. Why we may need to shard
Too much data Too much throughput Physical isolation

56. What’s next?
Going global?
Do we need to go global?
Can we leverage a CDN?
Would independent
systems be more suitable?
What consistency do
we need for the data?
