Why Kubernetes networking is hard – and what you can do about it

 

History tells us that networking is always the last piece of the puzzle. From mainframes, to virtual machines, and now with containers, providing compute and storage are the first two steps before the realisation sets in that all these little entities have to all communicate with each other.

For most of the last 30 years, that communication has been facilitated over Ethernet where different ends of a communication at the application layer bind to each other using IP addresses and port numbers. But...

GoDaddy goes all-in on AWS, citing containers expertise as key

Hosting provider GoDaddy is going all-in on Amazon Web Services (AWS) moving the ‘vast majority of its infrastructure’ over to Amazon as well as maintaining an active interest in containerised apps.

The move, announced by AWS, will see GoDaddy utilise various services, including Amazon EKS, its elastic container service for Kubernetes launched at the company’s re:Invent event at the end of November. Other services being used include P2, AWS’ general purpose GPU instances ‘to...

Kubernetes takes step up as it ‘graduates’ from Cloud Native Computing Foundation

It’s official: Kubernetes has hit the big time. According to a missive from the Cloud Native Computing Foundation (CNCF), the Google-designed, CNCF-maintained project is the first to ‘graduate’ from its foundation, throwing its mortarboard in the air in time-honoured tradition at the Open Source Leadership Summit in Sonoma Valley, California.

So what does this actually mean? Each technology adopted by the CNCF – of which there are 16 including Kubernetes – theoretically goes...

Five cloud computing predictions for 2018: Containers, AI, and custom clouds

Just a few years ago, not many predicted cloud computing would reach the heights we’ve seen in 2017 – 79 percent of companies now run workloads in the cloud (split almost evenly between public and private clouds). With the cloud bar constantly being raised, where do we go from here? Here are five predictions for the future of cloud computing in 2018.

True hybrid clouds emerge

Hybrid cloud is all the...

Kubernetes launches version 1.8 with focus on security and sustainability

The latest iteration of Kubernetes has launched, with the open source company promising 1.8 will be laser focused on security and sustainability.

The launch – the third of its type this year – offers a variety of new initiatives, from greater support for role based access control (RBAC), to transport layer security (TLS), to promotion for a series of workload APIs.

“Kubernetes 1.8 represents a snapshot of many exciting enhancements and refinements underway,” a company post explained....

Enterprise container adoption remains slow despite the hype, research argues

Enterprise interest in container technologies continue to grow, but adoption has not gone up with it, according to a report from the Cloud Foundry Foundation.

The Global Perception Study report, which polled more than 540 enterprise developers across different industries, found that only 25% of organisations polled were using containers in 2017, up only 3% from 22% in 2016. There was, however, a greater uptick in companies evaluating options, at 42% from 31% in 2016.

Perhaps this is somewhat to be expected;...

Where is the true state of the cloud in 2017? Analysing two influential reports

(c)iStock.com/Serjio74

Two reports have hit this publication’s inbox around the ‘state of the cloud’ in recent days; a study from RightScale argues the market is growing at a solid clip, while the summary from Bessemer Venture Partners’ (BVP) Byron Deeter found an industry which struggled at the start of 2016 but has since roared back.

While both reports differ – RightScale focuses on the adoption and vendors, while Deeter looks almost exclusively at the financial angle –...

Why Kubernetes promises much for those willing to embrace a cultural shift

(c)iStock.com/Sjoerd van der Wal

Opinion It’d be fantastic if developers could write one piece of code on their machine and have full confidence it could run on any server without a glitch.

This is far from the norm as the technical headaches of pushing code on to different servers and environments can have profound consequences for any organisation. This can undermine confidence and slow down the roll-out of new apps and amendments to them.

Things are changing though, as the technology supporting cloud...

Containers going mainstream, but deployment still a headache

(c)iStock.com/Sjoerd van der Wal

A survey of 200 IT professionals surveyed by IT and cloud operations provider NetEnrich has revealed that 70% are using containers today, but integration with existing IT environments remains a challenge.

The research found that while seven in 10 use container technology, with another 21% of respondents indicating they plan to move soon, more than half (55%) admitted integrating containers into current IT systems was the biggest issue. Security concerns (53% of respondents)...

Conducting containers in the cloud: Evaluating orchestration options

(c)iStock.com/cyano66

The standard has been set for containerisation. It’s Docker. Need an identical copy of your application stack in multiple environments? Package it once for Docker and away you go. It’s simple, and it’s why we love containers. That was all you needed back in 2015 – but things are changing fast.

Now that containers have proved their viability, it’s on to the next big area for innovation: orchestration. This is where there’s even more competition and the...
