It’s a new world for applications…


4

They are…

• Built to run in a single data center

• On servers you control

• And a infrastructure that you pre-provision for peak capacity

– Which is expensive

• Using a centralized database

• Where availability relies on resilient infrastructure

• Often in monolithic code blocks with hard-coded

dependencies between functions

The trouble with pre-cloud applications

Out with the old, in with the new…

Assumptions… what your mother said…

• Infrastructure is resilient

• Infrastructure is pre-provisioned

• Infrastructure drives scaling

• Disaster / recovery methods are sound

• Infrastructure is “variable”

• Infrastructure is elastic

• Applications drive scaling

• Continuous availability is the goal (no disaster)


8

Architecture is different

• Monolithic apps are not great, but they work

• Functions that are highly dependent are co-located

• Application portability is hard

• Applications are operated by I&O teams

• Micro services are they way, even if complex

• Functionality should be widely distributed

• Application portability is easy (with Docker)

• Services are operated by developers


9

Operations. Word.

• A VM is a VM is a VM

• Servers are pets

• BAU can work in cloud

• Applications run in a data center

• Clouds are like snowflakes

• Servers are cattle

• Most of what you do will change

• Applications span data centers, regions, borders


10

At your (micro) Service..

Micro services = SOA

Assemble services, not componentsBe asynchronous until you can’tMicro services increase agility, and complexity


11

Horizontal scaling is critical, and hard

The importance of being small

Predictability requires testing and tuning

Where is state managed

When bad things happen to good VMs


12

Resilience – when applications own it

When the application owns its resilience, infrastructure can be less expensive…


13

Globally distributed

Putting the application and the data where the customers live and work


14

Are…

• Built to run across data center, geographies, etc.

• On servers in the cloud

• That you provision when you need them and kill when you

don’t

• Using a distributed cloud database

• Where availability is built in

• Using micro-services, RESTful interfaces
