The Innovation Gap in Traditional IT

Developer Operator

“The traditional model is that you take
your software to the wall that separates
development and operations, and throw
it over and then forget about it.”
“Not in Amazon.
You build it. You run it.”

Application container runtime with data
services, automated build pipeline,
routing, health management , APM and
logging.
API-based infrastructure provisioning
that delivers bit-for-bit, consistent, self-
healing deployments across private and
public cloud.
A complete framework for delivering software rapidly,
consistently and reliably at scale.

• Multi-cloud platform, that is
infrastructure agnostic
• Single pane of glass visibility
into entire platform
• Enables portability and
security of applications

What are Microservices ?
Loosely coupled service oriented architecture with bounded
contexts
If every service has to be updated in
concert, it’s not loosely coupled!
If you have to know about surrounding
services you don’t have a bounded
context.

- Managed
independently
- Not held up by
slowest “train”
- Fits cloud native
“scale-up” model
- Reduces risk
