Kubernetes Trials & Tribulations Q&A: Cloud, Data Center, Edge

Kubernetes cloud orchestration platforms offer all the flexibility, elasticity, and ease of use — on premises, in a private or public cloud, even at the edge. The flexibility of turning on services when you want them, turning them off when you don’t, is an enticing prospect for developers as well as application deployment teams, but it has not been without its challenges.

At our recent SNIA Cloud Storage Technologies Initiative webcast “Kubernetes Trials & Tribulations: Cloud, Data Center, Edge” our experts, Michael St-Jean and Pete Brey, debated both the challenges and advantages of Kubernetes. If you missed the session, it is available on-demand along with the presentation slides. The live audience raised several interesting questions. Here are answers to them from our presenters.

Q: Are all these trends coming together? Where will Kubernetes be in the next 1-3 years?

A: Adoption rates for workloads like databases, artificial intelligence & machine learning, and data analytics in a container environment are on the rise. These applications are stateful and diverse, so a multi-protocol persistent storage layer built with Kubernetes services is essential. Read More

Kubernetes is Everywhere Q&A

Earlier this month, the SNIA Cloud Storage Technologies Initiative hosted a fascinating panel discussion “Kubernetes is Everywhere: What About Cloud Native Storage?”  where storage experts from SNIA and Kubernetes experts from the Cloud Native Computing Foundation (CNCF) discussed storage implications for Kubernetes. It was a lively and enlightening discussion on key considerations for container storage. In this Q&A blog, our panelists Nick Connolly, Michael St-Jean, Pete Brey and I elaborate on some of the most intriguing questions during the session.

Q. What are the additional/different challenges for Kubernetes storage at the edge – in contrast to the data center?  

A. Edge means different things depending on context. It could mean enterprise or provider edge locations, which are typically characterized by smaller, compact deployments of Kubernetes. It could mean Kubernetes deployed on a single node at a site with little or no IT support, or even disconnected from the internet, on ships, oil rigs, or even in space for example. It can also mean device edge, like MicroShift running on a small form factor computer or within an ARM or FPGA card for example.

One big challenge for Kubernetes at the edge in general is to provide a lightweight Read More

Business Resiliency in a Kubernetes World

At the 2018 KubeCon keynote, Monzo Bank explained the potential risk of running a single massive Kubernetes cluster. A minor conflict between etcd and Java led to an outage during one of their busiest business days, prompting questions, like “If a cluster goes down can our business keep functioning?”  Understanding the business continuity implications of multiple Kubernetes clusters is an important topic and key area of debate.

It’s an opportunity for the SNIA Cloud Storage Technologies Initiative (CSTI) to host “A Multi-tenant Multi-cluster Kubernetes “Datapocalypse” is Coming” – a live webcast on June 23, 2020 where Kubernetes expert, Paul Burt, will dive into:

Answering Your Kubernetes Storage Questions

Our recent SNIA Cloud Storage Technologies Initiative (CSTI) Kubernetes in the Cloud series generated a lot of interest, but also more than a few questions. The interest is a great indicator of Kubernetes rising profile in the world of computing.

Following the third episode in the series, we’ve chosen a few questions that might help to better explain (or bring additional context to) our presentation. This post is our answer to your very important questions.

If you’re new to this webcast series about running Kubernetes in the cloud, you can catch the three parts here:

The rest of this article includes your top questions from, and our answers to, Part 3:

Q. What databases are best suited to run on Kubernetes?

Kubernetes Links & Resources to Keep You in the Know

Our recent SNIA CSTI webcast, “Kubernetes in the Cloud (Part 3): (Almost) Everything You Need to Know about Stateful Workloads” offered a wealth of insight on how to address the challenges of running stateful workloads in Kubernetes. This webcast was the third installment of our Kubernetes in the Cloud webcast series and it is now available on-demand as are “Kubernetes in the Cloud (Part 1)” and “Kubernetes in the Cloud (Part 2).”

Our expert presenters, Paul Burt and Ingo Fuchs, have provided additional resources to help keep you in the know on Kubernetes. Here they all are:
