About Cloud Computing

“The market for cloud services is growing faster than virtually every other IT market today, with much of this growth coming at the expense of the traditional, non-cloud

We want to move fast, and yet not break things

slide-27

Our answer so far…

  • Business agility = Microservices
  • Infrastructure = CI/CD + containers
  • Process = Agile + DevOps
slide-28

…and this resulted in…

Modularization

  • Breaking up bigger things into smaller, more

manageable, parts

  • Cohesion over coupling
  • Modularity is the ultimate agile tool!

Trade-offs of decomposition

  • How to test?
  • How to deal with configuration
  • How to deal with dependencies?
  • How to deal with versioning?
  • How to deal with latency and overhead
  • How to deal with monitoring?
  • How to deal with …

DevOps

DevOps In Name Only

slide-41

Most traditional organizations…

  • Standardized technical infra components
  • Standardized hypervisor
  • Standardized operating system(s)
  • Standardized middleware
  • Standardized application development framework
  • Standardized programming language

2009 answer…

“A bunch of code I have to build & test together into a monolithic blob, which I then toss over the wall to an ops team, who hopefully get it to run on a fleet of servers. Then, I hope some work comes its way so I don’t waste too much $...”

slide-46

2019 answer…

“Managed services in the public cloud, connected and customized with highly differentiated business logic, that run (and bill) only when actually needed.”

Cloud-Native is a DevOps journey!

  • Cloud-Native is the architecture for assembling

cloud-based components in a way that is optimized for the cloud environment


  • It’s not about the servers, but the services

  • It’s about modernizing infrastructure and process,

and transforming the organizational culture along the way

Technologies or frameworks are not cloud-native, it is the way you use them

Getting the best from the Cloud

  • Potential for economic disruption

  • Ability to easily experiment with new technology or new business

ideas


  • Focus on strategic value vs managing infrastructure and

middleware

Now let’s talk about culture…

slide-64
SLIDE 64

Cloud-Native Culture Killers

  • Business does not trust IT, so no true BizDevSecOps
  • IT is a cost center
  • We only do cloud because it saves us money 


(we think)

slide-66
SLIDE 66

Cloud-Native Culture FTW!

  • We have an IT-first strategy
  • We see Cloud as a potential for economic disruption
  • Cloud enables us to start experiments (forward

thinking) and is our ability to innovate

  • Cloud enables a faster time-to-market
  • All our engineers are broadly skilled, and teams are

fully mandated
