● Revenue centric
● Single application focus,
eg e-commerce, online
banking
● Modern tools and skills
Case study example:
● Mondo Launches ‘Cloud
Native Bank’ on AWS
Enterprise Cloud Native
Enterprise
● Thousands of legacy
applications and
infrastructure
● Skills and tools challenges
So:
1. How impact existing
platforms and tools, eg
VMware?
2. Key goals: Consolidation
and cost savings, skills
overhaul, .. etc.
3. Additional design
requirements

Enterprise Cloud Maturity Model
From CMM Level 0..
● Legacy apps all on dedicated
infrastructure
● No use of IaaS
● No ALM processes
● Business context is missing
..to CMM Level 5
● Cloud Aware Applications deployed
according to governed business
requirements, across public,
private and hybrid platforms
● Federated multi-cloud via open
standards
● Automated deployment and
management
Cloud Aware Application
Maturity Model
● Excellent summary write up

Microservices are a modular approach to
software versus a single monolith.
““the microservice architectural style is an approach
to developing a single application as a suite of small
services, each running in its own process and
communicating with lightweight mechanisms, often an
HTTP resource API.”
Microservices and Continuous Deployment
Open Credo: Microservices Maturity Model
1 - Monolith Platform Single large codebase on bare metal in private data centre
2 - Meso Application
Platform
Meso systems emerge from organisations migrating away
from monolith, or adding new functionality to existing
applications via externally hosted smaller applications
3 - Microservices
Platform
Cloud native' loosely-coupled small services
IaaS, PaaS (private or public), or container cluster manager
(e.g. Mesos, Kubernetes)

● A great way to implement Microservices,
but not essential.
● Containers are a powerful deployment
tool, for any enterprise software. One part
of a DevOps Tool Chain.
● Docker is widely popular and offers
Enterprise solutions. Vendors like
VMware and Microsoft now build them in.
● Portability - The Image API
● Containers as a Service

A framework for implementing containers. For
example Apprenda offers an Enterprise PaaS
platform and recently acquired Kismatic to
manage Kubernetes clusters along with pools of
Windows and Linux servers dedicated to existing,
non-container based workloads.

Networking services are also being virtualized
and able to be deployed via containers. Docker
describes ‘Docker Networking’, aka ‘Network
DevOps’.
Docker acquired SocketPlane to embed
networking expertise and technologies into
Docker platform. Based on a primary model of
Native Docker Multi-Host Networking (Cloud
Aware Apps foundation).

DevOps Tool Chain
1. Teams organized by platform/technology and
have conflicting goals..
2. Automated provisioning of environments
3. Collaboration and shared decision making,
central automated processes across the
application lifecycle, processes are standardized
across the organization
4. Deployment pipeline automatically rejects bad
changes from version control
5. Zero touch continuous deployments.

be deployed at the press of a button, at all
times.
