Ably blog claims company doesn’t need Kubernetes to scale, surge in traffic takes down entire website • The Register

Published

on

A post on why using Kubernetes to scale would mean “doing mostly the same things but in a more complicated way” was so popular that the site hosting the article went down due to the sheer volume of traffic.

Maik Zumstrull is writer of code at Ably, a company which runs pub/sub (publish and subscribe) messaging services. He wrote a post titled “No, we don’t use Kubernetes” stating that the Google-invented container orchestration software is “very much at the peak of its hype cycle.”

However, he added that for what Ably does – “run a large scale production infrastructure that powers our customers’ real-time messaging applications around the world” – using Kubernetes would not help. His post appears to have been prompted by the fact that some customers and potential new recruits see this non-adoption as a problem. “We have even had interesting candidates walk away from job offers citing the fact that we don’t use Kubernetes as the reason,” Zumstrull said.

Ably seems on the face of it to be a good candidate for Kubernetes. “Our entire production environment exists on AWS,” said Zumstrull, with virtual machines running Docker and software deployed in containers.

He claimed that the features of Kubernetes were not required. Each VM instance is deployed to run a certain set of containers, which does not change for the life of the instance. Each set of containers maps to an AWS Auto Scaling group. There are “lightweight monitoring services” on each instance that monitor container health, respawn one that dies, and terminate the instance if a container goes out of date. “Because one autoscaling group equals one production service, we can use the normal AWS method of pointing one NLB [Network Load Balancer] at one autoscaling group as the target group, with no additional abstraction layer required,” he said.

The company has investigated Kubernetes and reckons it “would need at least ten clusters (one for each of ten regions).” Zumstrull said: “We would be doing mostly the same things, but in a more complicated way.” What about the benefits of Kubernetes, though, such as multi-cloud portability? Zumstrull is a multi-cloud sceptic. “The differences between the major cloud providers do matter, and Kubernetes does not succeed at abstracting them away,” he said.

Kubernetes would add cost, he argued, thanks to its complexity and the number of services that have to be configured on top of the platform.

It seems that Zumstrull’s post struck a nerve. Thanks to a discussion on Hacker News, the website was overwhelmed with traffic, causing Ably co-founder and CTO Paddy Byers to comment: “Ably CTO here. Well that went well…” Byers noted that although the website fell over (it was not just the blog), “the realtime service and website are different things. The blog post is talking about the service, which has been continuously available.”

As for the content of the post, opinions vary. “Perhaps my team runs a simpler cluster, but we have been running a Kubernetes cluster for 2+ years as a team of 2 and it has been nothing less than worth it,” said one comment; while another remarked that “my experiences with k8s have led me to never propose k8s in a new project. The k8s instances I have seen were bureaucratic and technical nightmares of unnecessary complexity. It doesn’t provide a common ground for deployments because everyone will use and configure it differently.”

The most telling comments, perhaps, were those about the benefits of standardisation and community. “Now live with your bad/good design patterns on your own for the life cycle of your product or service, you get none of the shared knowledge and advancement through the k8s community or platform,” said a Hacker News reader.

Even if Kubernetes is not the best solution now, if adoption and development continues at its present rate, it just might be in future.®

‘Disinfo kills’: protesters demand Facebook act to stop vaccine falsehoods | Facebook

Published

on

Activists are to descend on Facebook’s Washington headquarters on Wednesday to demand the company take stronger action against vaccine falsehoods spreading on its platform.

Protesters are planning to cover the lawn in front of Facebook’s office with body bags that read “disinfo kills” as a symbol of the harm caused by online disinformation, as Covid cases surge in the US.

The day of protest has been organized by a group of scholars, advocates and activists calling themselves the “Real” Oversight Board. The group is urging Facebook’s shareholders to ban so-called misinformation “superspreaders” – the small number of accounts responsible for the majority of false and misleading content about the Covid-19 vaccines.

“People are making decisions based on the disinformation that’s being spread on Facebook,” said Shireen Mitchell, Member of the Real Facebook Oversight Board and founder of Stop Online Violence Against Women. “If Facebook is not going to take that down, or if all they’re going to do is put out disclaimers, then fundamentally Facebook is participating in these deaths as well.”

In coordination with the protest, the Real Oversight Board has released a new report analyzing the spread of anti-vaccine misinformation on Facebook during the company’s most recent financial quarter. The report and protest also come as Facebook prepares to announce its financial earnings for that same quarter.

The report references a March study from the Center for Countering Digital Hate (CCDH) that found a small group of accounts – known as the “dirty dozen” – is responsible for more than 73% of anti-vaccine content across social media platforms, including Facebook. That report recently drew attention from the White House, and Joe Biden has condemned Facebook and other tech companies for failing to take action.

Facebook banned misinformation about vaccines from the platform in February of 2021, but critics say many posts slip through the platform’s filters and reach audiences of millions without being removed.

It also has introduced a number of rules relating to Covid-19 specifically, banning posts that question the severity of the disease, deny its existence, or argue that the vaccine has more risks than the virus. Still, the Real Oversight Board found that often such content has been able to remain on the platform and even make its way into the most-shared posts.

According to the Real Oversight Board’s report, a large share of the misinformation about the Covid vaccines comes from a few prolific accounts, and continues to be among the platform’s best performing and most widely shared content. It analyzed the top 10 posts on each weekday over the last quarter and found the majority of those originated from just five identified “superspreaders” of misinformation.

“When it comes to Covid disinformation, the vast majority of content comes from an extremely small group of highly visible users, making it far easier to combat it than Facebook admits,” the board said, concluding that Facebook is “continuing to profit from hate and deadly disinformation”.

The group has called on Facebook to remove the users from the platform or alter its algorithm to disable engagement with the offending accounts. Facebook did not immediately respond to request for comment, but has stated in the past it has removed more than 18m pieces of Covid misinformation.

Congress has also taken note of the spread of vaccine misinformation on Facebook and other platforms, with the Democratic senator Amy Klobuchar introducing a bill that would target platforms whose algorithms promotes health misinformation related to an “existing public health emergency”.

The bill, called the Health Misinformation Act, would remove protections provided by the internet law Section 230, which prevent platforms from being sued over content posted by their users in such cases.

“For far too long, online platforms have not done enough to protect the health of Americans,” Klobuchar said in a statement on the bill. “These are some of the biggest, richest companies in the world, and they must do more to prevent the spread of deadly vaccine misinformation.”

Workday shares slide following claims Amazon ditched company-wide HR system • The Register

Published

on

Amazon has halted plans to roll out a company-wide HR system based on SaaS from Workday, highlighting the challenges of migrating to the in-vogue application model.

A deal between the megacorp and Workday, an enterprise application interloper, was signed in 2017 with Amazon HR veep Beth Galetti at the time declaring: “Workday is an HR cloud leader that provides an innovative, customer-focused HCM system that will support Amazon as we continue to hire employees around the world.”

Three years later, the Seattle book-seller-cum-enterprise-juggernaut has changed its tune. According to reports, a migration from Oracle’s PeopleSoft has come unstuck because Workday’s database, an in-memory system that drew inspiration from SAP’s HANA, did not scale to the needs of Amazon’s increasing number of employees. In 2017, around 300,000 worked for the firm worldwide. Now it is around 800,000 in the US and 1.3 million worldwide.

Reports claim that some Amazon businesses, like streaming platform Twitch, are using Workday’s HR system, but for the main part, the organisation still relies on Oracle’s PeopleSoft.

In a blogpost, Workday said it and Amazon had both “mutually agreed to discontinue Amazon’s Workday Human Capital Management deployment,” based on a decision taken “more than a year and a half ago.”

It said there was “the potential to revisit [the project] in the future” and denied the decision was “related to the scalability of the Workday system.” One of its largest retail customers supported 1.5 million workers worldwide, it said.

“At times… customers have a unique set of needs that are different from what we’re delivering for our broader customer base, as was the case with Amazon – one of the most unique and dynamic companies in the world,” the statement said.

The Register has approached Amazon for comment.

Workday’s shares slid by as much as 7.8 per cent when news of Amazon’s decision broke.

It is not only megacorps that seem to struggle to implement Workday software. In the last year, two North American public-sector projects have become mired in difficulties.

The State of Maine ordered an official review of its $54.6m project to renew its HR system based on software from Workday, accusing the vendor of showing “no accountability” for its part in a flawed project which could leave the state government continuing to rely on its 30-year-old mainframe-based system.

At the time, Workday told The Register it was “committed to partnering with the State of Maine to successfully complete this project.”

Meanwhile, teaching assistants at Canada’s McGill University spent Christmas waiting to be paid as the institution struggled with a new Workday HR and payroll system, according to the Association of Graduate Students Employed at McGill (AGSEM). ®

What are the most in-demand jobs in automation, AI and RPA?

Published

on

Hays’ Tim Olsen discusses the job landscape within the automation and AI sector and the most valuable skills for workers in this area.

Click to read more stories from Automation Week.

Automation is one of the most rapidly growing job markets right now, incorporating artificial intelligence (AI), machine learning, and robotic process automation (RPA).

Why the rise in demand for automation?

Businesses are realising the untapped potential of intelligent automation. As more adopt automation, those that do not are becoming less productive and will likely be left behind. An awareness of the value of automation is nothing new, but the boom in demand is largely driven by a need for greater efficiency, rapid deployment and scalability.

According to Deloitte’s 2020 survey, two-thirds of organisations surveyed also note the Covid-19 pandemic’s role in accelerating demand for automation. For these organisations, automation has facilitated remote working and helped them meet an increase in processing requirements.

It is no longer the case of whether to automate, but when, and the best time is always now.

RPA is a well-proved technology, but the integration of AI and other cognitive technologies broadens the scope of what can be automated and the scale of its benefits. This is accelerating the market even faster, and those with skillsets in both domains are therefore in high demand.

This demand is reflected in the training courses now available. Microsoft recently launched its own AI offering, Azure Applied AI Services, and MIT has just introduced a new RPA diploma course to meet market demand. Yet this is still a candidate-short field. The sector is growing more quickly than the skillset.

The value of transferable skills in automation

Jobs are often well-paid. In the UK for example, Glassdoor shows that RPA developers are paid, on average, £6,000 more than other developers. And jobseekers may already have some of the skills that recruiters are looking for.

I began my career on the shop floor selling mobile phones and was promoted to a management position before becoming a project manager, where I worked on speech technologies for Vodafone. Later, I moved to Capita, where I helped scale its automation department from three people to 177.

Automation has been my focus ever since, and I have seen first-hand how challenging it can be to find the right candidates to fill these roles. It is about getting that depth and breadth of skills that is difficult in the market. There are many transferrable skills which can help create a pipeline from a variety of jobs into the world of automation. Recruiters want to see that you have battle scars.

The most in-demand jobs in automation, AI and RPA

Project managers and business analysts are sought-after, while systems architects and lead developers are in particularly high demand. Experienced centre of excellence programme leads can be hard to come by, so are in highest demand.

It all comes down to experience. There are many candidates who claim to have RPA experience, but few of them have applied their skills broadly across multiple industries. People who can demonstrate a breadth of experience, including in cognitive technologies, are in highest demand.

While there are many developers in Blue Prism and UiPath, Automation Anywhere, developers are still scarce, and organisations are being forced to look overseas for resources. Knowledge of associated technologies such as cloud, chatbots and natural language processing are highly rated, while business analysts increasingly need to have deep knowledge of the vendor ecosystems and process/task mining to differentiate themselves from the competition.

How to get a job in automation, AI and RPA

This is a growing sector, so newcomers can build their skills to make them employable in the longer-term. While there is no substitute for years of experience, many employers will be willing to overlook a lack of experience if the candidate can demonstrate key transferable skills, soft skills such as problem-solving abilities, or a commitment to learning and professional development.

Business analysts and project managers should be diplomatic with good communication skills. They should also understand the benefits of automation. Often, this job will involve learning how to automate certain areas of an employee’s job, which can make people concerned that their role is becoming obsolete. A good business analyst or project manager will be able to get all the information they need about a particular role while explaining how automation will help to make their jobs easier and more fulfilling.

Developers should consider specialising in complimentary technologies, such as cloud computing. As Microsoft’s Azure suite shows, the cloud can act as an entry point to the world of automation, so any awareness of cloud technology will help you understand how automation can work.

Potential candidates could sign up for online training with companies such as UiPath, Blue Prism or Automation Anywhere. These companies are on the cutting edge of AI, RPA and automation, and UiPath and Automation Anywhere currently offer free training courses that are recognised by most corporates with an interest in this field.

However, in such a fast-moving sector, it is important to top up your skills and qualifications, even after establishing your career.

Automation is the future

Automation, AI and RPA will transform the jobs market over the next few years. However, there is still fear around the impact automation could have on traditional jobs, and automation leaders around the world have been calling for an ethical roll-out of automated services.

For instance, companies might initially use automation to remove the more monotonous tasks which do not require much human engagement.

It is not about taking the human out of the equation; it is about taking the robot out of the human and liberating intellect. This takes away the drudgery of work and leaves people free to build relationships and be more creative.

Automation, AI and RPA can improve efficiencies, reduce costs and minimise churn. But there will always be a role for human interaction – whether that involves ‘managing’ your digital workforce as an automation specialist, or engaging with clients, colleagues and vendors.

The workplace will inevitably see a shift towards intelligent automation, and the most in-demand jobs will change over time, but the sector is here to stay.
