Kubernetes in Industries
Let’s learn something new today…
🤔What is Kubernetes❔
KUBERNETES also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.
Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation.It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
Rise of kubernetes(K8s):
Kubernetes has proven to be more than just Borg for everyone. It has distilled with most reliable API patterns and architectures of prior software. It has coupled them with current authorization policies, load balancing, and other features that are required to manage and run applications at massive scale. In turn, this provides developers with the groundwork for cluster abstractions to enable true portability across clouds.
With the explosion of innovation around Kubernetes, businesses have started to analyze obstacles for complete adoption. Many giants in the industry have increased investing resources and assuring mission-critical workloads. Fortunately, Kubernetes got a better response for the wave of adoption that swept to the forefront of crowded container management space.
Let’s see some case studies where industries are solving there challenges.
CASE STUDY:
👉 case study-1:
company: Pearson
Challenge
A global education company serving 75 million learners, Pearson set a goal to more than double that number, to 200 million, by 2025. A key part of this growth is in digital learning experiences, and Pearson was having difficulty in scaling and adapting to its growing online audience. They needed an infrastructure platform that would be able to scale quickly and deliver products to market faster.
Solution
“To transform our infrastructure, we had to think beyond simply enabling automated provisioning,” says Chris Jackson, Director for Cloud Platforms & SRE at Pearson. “We realized we had to build a platform that would allow Pearson developers to build, manage and deploy applications in a completely different way.” The team chose Docker container technology and Kubernetes orchestration “because of its flexibility, ease of management and the way it would improve our engineers’ productivity.”
Impact
With the platform, there has been substantial improvements in productivity and speed of delivery. “In some cases, we’ve gone from nine months to provision physical assets in a data center to just a few minutes to provision and get a new idea in front of a customer,” says John Shirley, Lead Site Reliability Engineer for the Cloud Platform Team. Jackson estimates they’ve achieved 15–20% developer productivity savings. Before, outages were an issue during their busiest time of year, the back-to-school period. Now, there’s high confidence in their ability to meet aggressive customer SLAs.
👉 case study-2:
company: ING
Challenge
After undergoing an agile transformation, ING realized it needed a standardized platform to support the work their developers were doing. “Our DevOps teams got empowered to be autonomous,” says Infrastructure Architect Thijs Ebbers. “It has benefits; you get all kinds of ideas. But a lot of teams are going to devise the same wheel. Teams started tinkering with Docker, Docker Swarm, Kubernetes, Mesos. Well, it’s not really useful for a company to have one hundred wheels, instead of one good wheel.
Solution
Using Kubernetes for container orchestration and Docker for containerization, the ING team began building an internal public cloud for its CI/CD pipeline and green-field applications. The pipeline, which has been built on Mesos Marathon, will be migrated onto Kubernetes. The bank-account management app Yolt in the U.K. (and soon France and Italy) market already is live hosted on a Kubernetes framework. At least two greenfield projects currently on the Kubernetes framework will be going into production later this year. By the end of 2018, the company plans to have converted a number of APIs used in the banking customer experience to cloud native APIs and host these on the Kubernetes-based platform.
Impact
“Cloud native technologies are helping our speed, from getting an application to test to acceptance to production,” says Infrastructure Architect Onno Van der Voort. “If you walk around ING now, you see all these DevOps teams, doing stand-ups, demoing. They try to get new functionality out there really fast. We held a hackathon for one of our existing components and basically converted it to cloud native within 2.5 days, though of course the tail takes more time before code is fully production ready.”
