Containing your microservice sprawl

1. Containing
Your
Microservice
Sprawl
Your fast path to
business agility

2. A discussion on 3 basic challenges to controlling
your microservice sprawl:
1) Lack of organization.
2) Ambiguous service ownership and profile.
3) Reactive approach – lack of visibility.
Microservices without the complexity.

4. Introducing DeployHub and Ortelius
• Ortelius is a microservice management platform that versions and tracks microservices,
their blast radius, and inventory across clusters providing a proactive view of your
microservice architecture as it changes overtime.
• Ortelius is an incubating project under the governance of the CD. Foundation (Linux
Foundation).
• Our mission is to simplify the adoption of microservices through a world-class
microservice management platform driven by a supportive and diverse global open-
source community
• DeployHub contributed 80% of the DeployHub codebase to the open-source
community.

5. A Microservice Architecture
A service-oriented
architecture (SOA) that
uses APIs instead of a
‘service bus.’
In MSA, the concept of
an ‘application’ is
‘logical.’ SOA was still
monolithic.
‘fine-grained SOA’

6. Microservices require new DevOps Solutions
New markets for a massive shift in how we write and deliver software
“ 92% - Use containers in production. Up from 84% last year, and up 300% from the first
CNCF survey in 2016.
83% - Use Kubernetes in production. Up from 78% last year.”
CNCF – Linux Foundation 2020 Survey
“Trend #1: Emergence of the Service Catalog. Potential $500M Market That Redefines the
Foundational Nature of Development Infrastructure.”
“Trend #2: Convergence of Continuous Delivery, GitOps, and Experimentation Vendors Are
Creating the Potential for a $500M ARR Progressive Delivery Mega-Market.”

7. Moving to
Microservices
We are taking our
static application
and breaking it into
smaller puzzle
pieces.
"What happened is we would release an update to a library, and
then one service would use the new service and now all of a
sudden all these other services were using an older version and
we had to try to keep track of which service was using what
version of the library."

management”

• Service
Granularity
• Independently
Deployed
• Polyglot
programming
• Reusable but
loosely coupled
• Fault Tolerance
and Auto Scaling

9. The Problem
• Lack of Organization
• Microservice sprawl is common as
multiple services are written by multiple
teams to do the same function.
• Lack of Service ownership and Profile
• Who wrote it and who uses it?
• What Version are we using?
• Reactive approach
• Impact of a service discovered after a
deployment using observability

10. Problem - Lack of Organization
Implement a Domain Driven Design
Domain-driven design (DDD)
facilitates the organization and
modeling of services based on
relevant business ‘problem spaces.’
DDD defines ‘problem spaces’ as
Bounded Context.
DDD identifies patterns to further
organize the development and
usage of services in defined ‘layers.’ Source - Microsoft Docs -
https://docs.microsoft.com/en-
us/dotnet/architecture/microservices/microservice-ddd-cqrs-
patterns/ddd-oriented-microservice

11. Problem - Lack of Organization
Solution - DeployHub’s Domain
Driven Design
DeployHub provides a DDD model to
publish and centralize services based on
the Domain Model with Sub-Domains to
represent all ‘layers.’
DeployHub’s Domain Model encourages
reuse of microservices by providing a
central catalog organized by ‘problem
spaces’ making sharing easy.

12. Problem - Lack of Service Ownership and Profile
Tracking Ownership and Versions.
Unclear:
• Who created the service?
• Who uses the service?
• What version of the service is
running where?
• What is the deployment meta data,
like Key Value Pairs?

13. The DeployHub
Service Catalog is a
logical collection of
microservices and
how they relate to
logical applications.

17. Problem Reactive Approach
A new version of a microservice impacts all consuming ‘logical’ applications.
We call this the ‘Blast Radius.’
Solution - DeployHub’s Proactive Visibility
Knowing your Blast Radius can reduce errors and incidents
while increasing your microservice sharing by as much as
50%.

18. Problem Reactive Approach
Solution - DeployHub’s Proactive Visibility
Before you ever release a
microservice, DeployHub can
tell you which consuming
application teams will be
impacted and where the
updates need to be installed
across Clusters and
Namespaces.

19. Bonus – Tracking Logical Applications
DeployHub starts the process by defining a logical application based on what services
it consumes.
The Blast Radius is tracked based on this Application ‘base version’ information.

20. DeployHub Automated Configuration Managment
1
Container Registry Push.
Triggers DeployHub to version microservices,
track application configuration management
and builds relationship maps.
2
Scheduled, on-demand or
CD triggers the deployment.
3
DeployHub records and tracks
inventory across all clusters.
4

PostgreSQL
Datastore

21. DeployHub Automated Configuration Management
As new container images are registered, DeployHub creates a new version of the
microservices, and a new version of the ‘logical’ application.
DeployHub’s secret sauce is a version control engine, built on top of a relational
model and datastore.

24. Summary – Microservices without Complexity
Controlling the Sprawl
DeployHub’s microservice catalog simplifies microservices by providing a proactive
view of microservices, their versions and usage across all of your clusters.
• Improve confidence and eliminate risk - know your microservice ‘blast radius’ before you go.
• Restore control - create your ‘logical application’ with
versions and change tracking.
• Add visibility - version your microservices and track their
inventory across all clusters.
• Reduce development cost - encourage microservice reuse organized by domains, relationships,
and usage.

25. The Results
Visibility gives Site
Reliability Engineers
the clarity of what’s
going on and the
ability to make data-
driven decisions
quickly before a
deployment.
