How Docker Has Changed the DevOps Game | @DevOpsSummit #DevOps #Docker #Containers

Software build, packaging, and deployment play a crucial role in release management

Cloud computing has paved the way for programmable infrastructure, which brought extreme automation into software development lifecycle. The ability to provision resources, configuring them on the fly, deploying applications, and monitoring the entire process led to the DevOps culture where developers and the operators are collaborating throughout the application lifecycle. While provisioning and configuration are best left to tools such as Chef, Puppet, and Ansible, one open source software that became the cornerstone of DevOps is Jenkins.

Software build, packaging, and deployment play a crucial role in release management. Enterprise developers often relied on tools such as Make, MS Build, Ant, Maven, and Gradle to compile and link source code. The rise of polyglot programming and distributed development increased the complexity of build management. That’s exactly where Jenkins comes to the rescue of development teams. By automating the build process, Jenkins can efficiently orchestrate complex workflows required by large teams. By integrating with the source code control system, Jenkins can invoke multiple build processes targeting different environments. The output of this would result in a set of EXEs, DLLs, or JAR files depending on the platform. Jenkins can also build free-style software that doesn’t rely on specific build tools like Ant and Maven. It can invoke simple shell scripts to perform pre-build and post-build tasks. This option enables Node.js, Python, Ruby and other environments to take advantage of build automation.

During the last couple of years, Docker moved fast to become the preferred environment for software development and testing. DevOps teams are finding it efficient to configure dev/test environments based on Docker. It has also revolutionized software packaging and deployment. Instead of deploying the final set of artifacts such as EXE and JAR files to the target environment, ops teams are now packaging the entire application as a Docker Image. This image shares the same build version before getting published to a central registry. It is then picked up by various environments – development, testing, staging, and production – for final deployment. So, Docker has essentially become the de facto packaging format for binaries.

@DevOpsSummit Stories
In his session at @DevOpsSummit at 20th Cloud Expo, Kelly Looney, director of DevOps consulting for Skytap, showed how an incremental approach to introducing containers into complex, distributed applications results in modernization with less risk and more reward. He also shared the story of how Skytap used Docker to get out of the business of managing infrastructure, and into the business of delivering innovation and business value. Attendees learned how up-front planning allows for a clean separation between infrastructure, platform, and service concerns.
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chief Architect at Cedexis, covered strategies for orchestrating global traffic achieving the highest-quality end-user experience while spanning multiple clouds and data centers and reacting at the velocity of modern development teams.
In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
"At the keynote this morning we spoke about the value proposition of Nutanix, of having a DevOps culture and a mindset, and the business outcomes of achieving agility and scale, which everybody here is trying to accomplish," noted Mark Lavi, DevOps Solution Architect at Nutanix, in this SYS-CON.tv interview at @DevOpsSummit at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.

DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and controlling infrastructure. The rise of Site Reliability Engineering (SRE) is part of that redefinition of operations vs development roles in organizations.
When you focus on a journey from up-close, you look at your own technical and cultural history and how you changed it for the benefit of the customer. This was our starting point: too many integration issues, 13 SWP days and very long cycles. It was evident that in this fast-paced industry we could no longer afford this reality. We needed something that would take us beyond reducing the development lifecycles, CI and Agile methodologies. We made a fundamental difference, even changed our culture.
As many know, the first generation of Cloud Management Platform (CMP) solutions were designed for managing virtual infrastructure (IaaS) and traditional applications. But that’s no longer enough to satisfy evolving and complex business requirements. In his session at 21st Cloud Expo, Scott Davis, Embotics CTO, will explore how next-generation CMPs ensure organizations can manage cloud-native and microservice-based application architectures, while also facilitating agile DevOps methodology. He will explain how automation, orchestration and governance are fundamental to managing today’s hybrid cloud environments and are critical for digital businesses to deliver services faster, with better user experience and higher quality, all while saving money.
Most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes a lot of work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reduction in cost and increase in speed.
SYS-CON Events announced today that Datera, that offers a radically new data management architecture, has been named "Exhibitor" of SYS-CON's 21st International Cloud Expo ®, which will take place on Oct 31 - Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA. Datera is transforming the traditional datacenter model through modern cloud simplicity. The technology industry is at another major inflection point. The rise of mobile, the Internet of Things, data storage and Big Data are challenging the existing design patterns of the Data Center. The increase in complexity of managing legacy systems alongside new systems is beyond the ability of most IT departments. This leads to multiple tiers of storage and high economic costs, during a time in which IT is expected to do more with less.
“Why didn’t testing catch this” must become “How did this make it to testing?” Traditional quality teams are the crutch and excuse keeping organizations from making the necessary investment in people, process, and technology to accelerate test automation. Just like societies that did not build waterways because the labor to keep carrying the water was so cheap, we have created disincentives to automate. In her session at @DevOpsSummit at 20th Cloud Expo, Anne Hungate, President of Daring Systems, discussed how to break the cycle of manual testing as de-facto – empowering development and quality to lead with automation. Learn about the changes in reporting, behaviors, and communication necessary to make automation the first choice.

Given the popularity of the containers, further investment in the telco/cable industry is needed to transition existing VM-based solutions to containerized cloud native deployments. The networking architecture of the solution isolates the network traffic into different network planes (e.g., management, control, and media). This naturally makes support for multiple interfaces in container orchestration engines an indispensable requirement.
