DEVELOPMENT AND OPERATIONS


EMC PHILOSPOHY – DEVOPS TRANSFORMATION AT SCALE

AUTOMATED – Processes and analytics need to be

automated wherever possible. Manual, legacy approaches

are too costly and time-consuming.

AGILE – An iterative, flexible approach is required for

modernizing IT at scale. Traditional approaches towards

transformation take too long to deliver impact and value.

ALIGNED – Modernization strategies and priorities need to

be grounded in business value. The business case for

modernization won’t make sense for everything.

OPTIMIZED FOR VALUE CREATION

€


VALUE FIRSTBUILD-MEASURE-LEARN FEEDBACK LOOP

We start each project

by working with the

customer to identify a

number of value

hypothesis (goals) for

the end solution. For

each value

hypothesis/goal, we

agree how we would

verify the value and

feasibility of the goal

We measure the

success of a goal

through an “Actionable

Metric”

We then agree the Goal’s Minimum

Viable Product (MVP) i.e. the

smallest solution that can verify our

biggest assumptions around the value

and the technical risk

1. "We need a software architecture that has the following characteristics

supports small, independent, and high quality units"

2. "A concept for build/deployment/operations that is scalable and

supports fast and automated rollouts into the different environments

(test/stage)"

3. "We need concepts that show us what has to change in our infrastructure(storage/server/network) to match the requirements of the topics above"

• Scores application suitability to run in a cloud native / microservices environment.

• Configured indicator rules based on industry best practices such as the 12 factor app methodology.

– Inputs: WAR, EAR, JAR, ZIP or Folder (currently Java only)

– Outputs: HTML, CSV and XML reports

OVERALL APPLICATION ASSESSMENT

ASSESSMENT SCORES: SUMMARY OBSERVATIONS

• Applications use EJBs with JNDI for service

interfaces

• Local file system is being used by applications

• Applications are compiled with older versions of

Java, potentially created buildpack support issues

• Logging frameworks are being used which can

send output to other destinations as well as filter

events

• WebLogic APIs are being used which may not

available

Factor #1 – App Server Independance

FINDINGS

• Enterprise Java Beans are being used to

implement services

• JNDI is being used for service discovery

IMPLICATIONS

• EJBs are not supported on many cloud native

platforms

• EJBs utilize network protocols that are not cloud

friendly

PROOF OF TECHNOLOGY Proof the value proposition of the EMC platform

– Increase productivity of the application delivery pipeline

– Operational efficiency

– Governance (Availability, Resiliency, Security, Openness)

It includes, but is more than

– Showing that the installation works

– Showing that data is replicated

– Do a couple of workshops to „explain“ the products

Because

– There are 1000s of options for how to use the platform

– If you do it wrong, you will be frustrated

– You only know, whether the platform works for you, if the complete value chain is tested


THE COMPLETE VALUE CHAIN ?

• All parties have to be involved somehow, because– It is important to understand their needs for a proper platform design

– it makes them feel better

– Without end-to-end experiments you will not know, whether it works

• Experiments– Test assumptions

– Wow – effects (efficiency, fun)

– Test different design options (again, there are 1000s)

OUR RECOMMENDED APPROACH

2 Sprints (plus mobilization) covered by a T&M

budget:

For each of the ITIL domains/discipline EMC

shall produce jointly with client the following

outcome:

• Assessment (tools, org, parties involved

etc.)

• Possible DevOps transition based on best

practices (mapping for example Netflix)

• Implementation recommendations

(process changes, Org adaptations, tools,

automation, documentation)

• Prioritization of Change recommendations

• „Definition of Done“

• Complexity of implementation (risk and

reward)


SUMMARY

• Only do things that are relevant and urgent for your

business

• Make things measurable

• Think end-to-end

• Think cross-functional

• Go

• Agile Transformation: Konsequente Nutzung agiler Methoden über alle Teile der Wertschöpfungskette.

• Standardisierte, flexible Ziel – Plattform und voll-automatisierte “Deployment Toolchain”: Nutzung von PaaS (private-, public,

hybrid) - und Automatisierungslösungen, ausgerichtet an Standards, Vorkenntnissen und Anforderungen des Kunden. Dabei

betrachten wir vorhandene Lösungen und helfen, diese bei Bedarf zur Steigerung der Qualität und Effizienz der digitalen

Wertschöpfungskette zu optimieren.

• Software Architekturen & Werkzeuge: Entwickeln von Standards- und Best-Practices für Lösungsdesign und Umsetzung. Dabei

prägen sogenannte cloud-native Ansätze auf Basis von Microservices und dezentralen Daten- und Messagingstrukturen zunehmend

die technischen Designs von für moderne PaaS -Lösungen optimierten Lösungen. Design – Entscheidungen werden dabei immer

auf Basis der fachlichen und nicht-fachlichen Anforderungen getroffen und explizit durch unsere Berater hergeleitet und begründet.

• Infrastruktur Management: Standardisierte Definition und Implementierung eines Staging – Konzeptes und Regelung der

Betriebsprozesse sind essentiell für den Erfolg von Software – Lösungen, die in Cloud – Modellen zur Verfügung gestellt werden

sollen. Diese werden von Beginn an, sowohl technologisch als auch organisatorisch, insbesondere bzgl. der Governance Themen

mit beleuchtet.
