stackconf 2021 | How DevOps changed the way we operate software

Jun 25, 20210 likes38 views

It’s been more than a decade since the inception of devops. A lot has changed since then. We now live in a world where many traditional ops responsibilities distributed among teams. We are also seeing a dramatic change in how we do ops. Ops people are now writing code and testing them the way developers write business logic. But does this give enough context? Of course not. In this talk, we are going to cover how devops change the way we create and run software – and talk about what is next!

THE PROBLEM DEVOPS AIMS TO SOLVE
Dev Ops

A culture where people, regardless of title or background, work
together to imagine, develop, deploy and operate a system.
DEVOPS DEFINITIONS I LIKE
Ken Mugrage

DevOps is the combination of cultural philosophies, practices, and
tools that increases an organization’s ability to deliver applications
and services at high velocity: evolving and improving products at a
faster pace than organizations using traditional software
development and infrastructure management processes.
DEVOPS DEFINITIONS I LIKE
Amazon Web Services
aws.amazon.com/devops/what-is-devops/

Let me explain.
YOU SAY DEVOPS IS NOT A JOB TITLE OR SOMETHING WE DO?
Companies have their own realities. Factors like legacy apps,
company size, sector or even engineer’s backgrounds affect
what DevOps is for them.

1. CREATE A CULTURE OF
SHARED RESPONSIBILITY
AMONG DEV AND OPS.

One goal

Customer oriented.
Ownership

Take responsibility.
Transparency

Open
communication.
Leadership
support

We trust you make
the best decision.
Culture of shared responsibility

F1 DRIVERS KNOW EACH
COMPONENT OF THE CAR VERY
WELL, NOT JUST ENGINES.

2. DEVELOPERS TAKE OWNERSHIP:
THEY SHIP, LOG, MONITOR AND
RESPOND TO INCIDENTS

2. DEVELOPERS TAKE OWNERSHIP:
THEY SHIP, LOG, MONITOR AND
RESPOND TO INCIDENTS
Dev - Ops

Gain empathy

Dev - Management

Increasing demands

WE DON’T HAVE TO
BUILD & MANAGE
 
A LOT OF THINGS
ON OUR OWN.

3. TURN TRADITIONAL OPS
INTO AN ENGINEERING ROLE.

3. TURN TRADITIONAL OPS
INTO AN ENGINEERING ROLE.
This does NOT mean using:

5. TRACK AND MEASURE
WHAT IS IMPORTANT FOR

THE BUSINESS.

An Emerging SRE Concept:

Service Level Objectives - SLO

How to measure “DevOps” success?

Remember: Tie technical goals to business goals

• Lead time for changes

• Deployment frequency

• Time to restore service

• Change failure rate

How DevOps changed the way we operate software
Created a shared responsibility among dev and ops

Developers started taking ownership

Ops became an engineering role

Built architectures to foster collaboration and ownership

Started measuring what matters for the business

Thank you!
SERHAT CAN | TECHNICAL EVANGELIST @ATLASSIAN | AWS COMMUNITY HERO | @SRHTCN

Most ops groups can’t give developers what they need. Ops is limited by traditional service delivery mindset and tools. Stability & reliability are now table-stakes when you are releasing software daily. What developers need now from ops is innovation. Operations has rarely taken this innovation-driven, product approach to providing services, & instead focuses on delivering to specification & limiting SLAs. As with development, ops creates value with continuous operations, product managing their platforms and releasing frequently. This talk covers how ops groups are transforming from a service delivery mindset a platform-as-a-product approach. With examples from Discover Financial Services, Rabobank, the US Air Force, & others the talk covers the concept, technologies & tools commonly used, & ops tactics needed to kick-off a platform-as-a-product strategy.

stackconf 2021 | Building the first European open source Edge Computing platf...NETWAYS

Edge Computing is becoming increasingly popular nowadays thanks to the growing availability of cloud, bare-metal and 5G providers offering flexible and affordable access to edge resources around the globe. The idea is based on moving core computational processes and storage to distant locations that are closer to the entities they interact with, like end-users and IoT devices. The benefits come from improving network latency and user experience, reducing security risks, and minimizing data transfers to central cloud locations. Thanks to the €2.1M awarded in 2019 by the European Commission as part of the Horizon 2020 SME Instrument Program, OpenNebula has developed the first open source Edge Computing platform in Europe. This talk analyses the benefits and challenges associated with Edge Computing, introduces the “True Hybrid Cloud” concept, and explores how this new EU-funded Edge Computing platform contributes to consolidate Europe’s digital sovereignty by integrating other relevant European open source technologies and by providing future access to the GAIA-X federated infrastructure.

stackconf 2021 | Data Driven SecurityNETWAYS

The value of Machine Learning researching malware is as important as the human experience. This presentation outlines why Data Driven Security is more effective than traditional research methodologies, as it combines data, human experience and logic made by machines to define the verdict. The audience is exposed to the background, why logic created by Machine Learning algorithms is defined ‘optimal’, in the sense of a mathematical reflection of the data and labels collected over time.

Going Cloud Native - It Takes a PlatformChip Childers

There is a lot of buzz about “cloud native.” Becoming cloud native means changing how we think about, develop, and deploy applications. This shift impacts the structure of organizations, as teams align to common business outcomes. Chip Childers explains why a successful cloud native approach requires a platform: a platform allows you to rethink how IT supports the application development teams. Chip explores what it means to be truly cloud native, what it takes to get there, and how a platform can make it all work.

The new stack isn’t a stack: Fragmentation and terraforming  the service layerDonnie Berkholz

Open source, cloud, and the API revolution have already changed the way we build software. What's next? Donnie's spent the past 5 years trying to figure that out through observation and research at RedMonk and now at 451 Research. In this talk, he'll share what he's seen and what he predicts for the future of how we develop applications. You'll hear buzzwords like DevOps and microservices used in ways that actually make sense (for a change), see real-world examples of companies that have succeeded and failed, and learn how approaches like the one taken by HashiCorp's Terraform (by the authors of Vagrant) will be critical to the future of how we build software.

stackconf 2021 | Reference Architecture for a Cloud Native Digital EnterpriseNETWAYS

In an era of digital transformation, (digital) enterprises are looking for fast innovation through effective collaboration to deliver more value to their customers with dramatically less effort. Digital enterprises enable companies of every sector to integrate, expose, and monetize their business capabilities by digitizing entire value chains. As a result, APIs have become the norm to expose integrated business functionalities to deliver an enhanced digital experience. Enterprises can start their digital transformation in greenfield or brownfield; in both cases, having a well-defined API-led integration architecture is important. Apart from integration and API platforms, these architectures should be able to provide agility, flexibility, and scalability. This session discusses a vendor/technology-neutral reference architecture for a cloud native digital enterprise to increase productivity by having agility, flexibility, and scalability through automation and services. The architecture discussed in this session can be mapped into different cloud-native platforms (Kubernetes and service mesh), different cloud providers (Microsoft Azure, Amazon AWS, and Google GCP), and infrastructure services to perform the implementation.

Microservices for MortalsBert Ertman

Microservices is the new popular kid on the block. Crowd pleaser at many conferences. With popular poster children such as Netflix and Amazon it seems to be the killer approach to 21st century architectures, right? But is this stuff only for Hollywood Coders pioneering on the bleeding edge of our profession? Or is this stuff ready to be used for your projects and your customers? This presentation is a warning. Microservices don't fix broken organizations and distributed computing is still hard. I will go over the benefits, but more so the pitfalls, of using a Microservices based architecture. What impact does it have on your applications, on dealing with scale and failures, and how do you prevent your systems landscape from becoming an unmaintainable nightmare.

DevOps Moves To Production (Lori MacVittie)Red Hat Developers

Delivering an app or service fast and frequently to production isn't the same as delivering the app or service fast and frequently to its intended users. Before an app is actually 'live' it has to run the gauntlet of production deployment that stands between it and real, live users. While DevOps has helped organizations make huge strides toward continuous delivery in dev and test environments, the production environment remains a very real obstacle in realizing continuous deployment. The biggest hurdle in that obstacle course is a narrow definition of DevOps that fails to include a broad set of technologies and tools outside the Dev and Ops domain. In this session we'll explore the underlying elements of a comprehensive DevOps approach (SDN, CD/CI, and Agile) and how they mix, match, and combine to enable the operational transformation DevOps promises to achieve the ultimate goal of IT agility: continuous deployment.

DCSF19 How To Build Your Containerization Strategy Docker, Inc.

Lee Namba, Docker The Docker Enterprise container platform helps organizations deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the container platform environment, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together. In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data and more), how your org chart can influence whether you deploy CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying containers into your enterprise.

A Hitchhiker's Guide to the Cloud Native StackQAware GmbH

Devoxx 2017, Poland: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware). Abstract: Cloud native applications are popular these days. They promise superior reliability and almost arbitrary scalability. They follow three key principles: they are built and composed as microservices. They are packaged and distributed in containers. The containers are executed dynamically in the cloud. But which technology is best to build this kind of application? This talk will be your guidebook. In this hands-on session, we will briefly introduce the core concepts and some key technologies of the cloud native stack and then show how to build, package, compose and orchestrate a cloud native microservice application on top of a cluster operating system such as Kubernetes. To make this session even more entertaining we will be using off-the-shelf MIDI controllers to visualize the concepts and to remote control a Kubernetes cluster.

Atmosphere Conference 2015: The 10 Myths of DevOpsPROIDEA

Speaker: Seth Vargo Language: English Although not officially coined until 2009, DevOps ideals have been explicitly discussed since at least 2006. Recently, however, the term "DevOps" has gained increasing popularity across a variety of fields and industries. DevOps is not a development methodology or technology; DevOps is an ideology. It is a way to facilitate organizational prosperity and growth while increasing each individual employee's happiness along the way. As DevOps has gained in prominence, a gap has been created between the original definition of DevOps and this new "enterprise-ready" buzzword. For organizations beginning DevOps practices, this talk will provide a 10,000ft view of DevOps and how you can properly implement DevOps practices in your organization. For organizations that are currently practicing DevOps, this talk will cover common pitfalls, ways to sustain a happy culture, and new tips to foster organizational prosperity.

AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATIONmiso_uam

AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATION (plenary talk at ANNSIM'2025) Testing is essential to improve the correctness of software systems. Metamorphic testing (MT) is an approach especially suited when the system under test lacks oracles, or they are expensive to compute. However, building an MT environment for a particular domain (e.g., cloud simulation, automated driving simulation, production system simulation, etc) requires substantial effort. To alleviate this problem, we propose a model-driven engineering approach to automate the construction of MT environments, which is especially useful to test domain-specific modelling and simulation systems. Starting from a meta-model capturing the domain concepts, and a description of the domain execution environment, our approach produces an MT environment featuring comprehensive support for the MT process. This includes the definition of domain-specific metamorphic relations, their evaluation, detailed reporting of the testing results, and the automated search-based generation of follow-up test cases. In this talk, I presented the approach, along with ongoing work and perspectives for integrating intelligence assistance based on large language models in the MT process. The work is a joint collaboration with Pablo Gómez-Abajo, Pablo C. Cañizares and Esther Guerra from the miso research group and Alberto Núñez from UCM.
