QCon New York 2016 : Sessions to consider, Day One

Fred Churchville Fred Churchville Profile: Fred Churchville

Got your QCon session schedule ready yet? If not, it’s worth making a plan to make sure you’re getting the most out of this conference that you possibly can.

Of course I recommend going to both of the Keynote talks: Incident Response: Trade-Offs Under Pressure and Engineering the Red Planet. But there are a lot of tracks and sessions to choose from in the meantime.

Here’s a sample schedule that takes you from the day’s first keynote to the last one. Be sure to view the full schedule and explore all your options, but these are the sessions that really stick out to me as either potentially very educational or simply just interesting.

The Netflix API Platform for Server-Side Scripting

10:35am, Salon D

Even the magicians at Netflix struggle with API management.

Katharina Probst is presenting this one — she’s the engineering manager at Netflix who leads their API team. She’ll be talking about how their taking their Groovy scripts and helping them pack up to live on their own in isolated containers while still communicating with their API via a data platform provider called Falcor.

While most of us don’t have to worry about streaming millions of people their favorite movies and shows, hopefully this will provide developers and architects some ideas about how they can solve some of the many challenges associated with building a truly cohesive API architecture.

Safe Systems Programming in C# and .NET

11:50am, Dumbo/Navy Yard

Joe Duffy, a director of engineering at Microsoft and former architect for the Midori OS, is leading this talk, and will dive into how he built an entire OS in a C# dialect. He also promises to go over things like garbage collection, low-level code quality and dealing with errors and concurrency robustly.

“I want to talk about the problems and how to solve them in C#,” Duffy said in an interview with QCon representatives. “A lot of it does come down to practices.  And the framework, it turns out, is as important as the language.

This one’s recommended for only those already working with C# or some other .NET language. Java coders: These are not the tips you’re looking for. Move along.

Data Science Meets Star Wars: The F#orce Awakens

1:40pm, Dumbo/Navy Yard

Like Star Wars? Like code? I think you’ll like this.

Evelina Gabasova, a machine learning researcher working in bioinformatics at Cambridge, is giving this talk. She will attempt to prove how easy it is to process large amounts of data using F# and R by using these languages to glean insights about the Star Wars franchise from public datasets.

“I want to make people aware that F# is a nice language for working with data,” Gabasova said in an interview with QCon representatives. “If you are doing any data science or machine learning, 95% of your time is spent getting data into a usable shape and I think F# is a great language for that.”

This talk seems like it’s definitely for those both working with and interested in working with F#. No word yet on whether Gabasova will be appearing in person or via hologram.

Your Org Should Think about Diversity, Yesterday

2:55pm, Salon C

This session will be presented by Swati Vauthrin, director of engineering at BuzzFeed, and she will discuss how focusing on creating a diverse software engineering team not only makes sense from a social perspective, but also from a business one.

“Not everybody fits the same mold, and I think that for us that’s been really powerful,” Vauthrin said in an official QCON interview. “It allowed us to think differently, to think about how we are engineering products differently.”

I picked out this session, because it’s easy to get wrapped up in the technology and forget that, at the end of the day, people are what matter. It may also be a healthy change in gears from the day’s more tech-heavy conversations.

Patterns and Practices for Cloud-Based Microservices

4:10pm, Dumbo/Navy Yard

You can’t have a truly complete day at a software development conference without at least a little dose of microservices.

Rachel Reese is a senior software engineer at Jet, a spunky startup set on competing with Amazon. She’s going to show us what the team at Jet has done with microservices in the .NET space (F# and Azure). But don’t let the .NET focus keep you from attending this session — it’s really for anyone interested at all in microservices.

“The most important takeaway is, if you already have microservices, consider going home and fix or change what you do into something better.” Reese said in a QCon interview. “For the folks who aren’t there yet, it’s encouraging you to be more aware of what you are getting into.”

Handling Streaming Data in Spotify Using the Cloud

5:25pm, Salon E

If you don’t use Spotify, I’m willing to bet you know someone who does. But did you know they nearly reached their limit when it came to data streaming? To handle their growing data rate of 60 billion events per day, their engineers had to figure out how they were going to successfully scale the event delivery system with Spotify’s growth before disaster struck.

Neville Li is a software engineer at Spotify who works mainly on data infrastructure for machine learning and advanced analytics.  He’s going to explain how they leveraged the new event delivery system on Google Cloud Pubsub and Google Cloud Dataflow to meet their scaling needs. Li will explain the lessons they learned from dealing with this data streaming issue, including why the cloud matters. He’ll also talk about Scio, a high level Scala API for the Dataflow SDK that made it easier to use.

This talk is a little technology heavy, but any engineers struggling with data streaming issues and trying to simplify things and reduce operational burdens should get something out of it.

Now it’s time for a day two schedule.

Why the election should have you thinking about aPaaS

Fred Churchville Fred Churchville Profile: Fred Churchville
aPaaS, Application development, PaaS

There’s an idea consistently being trumpeted on both sides of the election fence this year: shaking up the old established ways of politics and making a change. Whether or not you think that idea is scary, and unless poll numbers lie, you have to admit that people like it. So here’s an idea, developers: What happens if that same ideology is brought to the enterprise?

Today there are plenty of free tools and platforms available to make enterprise-grade apps, that a small pharmaceutical supply chain management company called AntTail was able to create a working, fully mobile business application prototype in days without spending a dime. The provider they leveraged, Mendix, is just one of the companies offering free sandboxing with their application- platform-as-a-service (aPaaS). OutSystems and IBM’s Simplicite are some others who let developers try their aPaaS tools without incurring any costs.

So for any company running, say, an old ESB or utilizing an expensive EDI-based VAN, what’s stopping a developer from throwing up his hands, saying “stop!” and presenting their boss with a working proof-of-concept application that does everything their old, monolithic systems just as effectively – if not better? And maybe – just maybe – that change could be enough to break the established, legacy ways of doing things within an organization and inject a new, more efficient approach to software management.

This does require the developer to take a little bit of a leap of faith when confronting their respective boss with their prototype software, and there certainly can be a lot at stake. What if it works in a small environment, but doesn’t translate so well to large environment? What if the service fails after implementation? What if a major security vulnerability is created?

This may be the thought process that keeps developers from kicking up too much dust, according to Mark Roemers, co-founder of AntTail, who admits that there is certainly a risk factor that should always be taken into consideration.

“People want to make sure they don’t make the wrong decision instead of being ambitious and going for goals,” said Roemers. “They’re risk averse, and I don’t blame them — it takes a certain spirit to be able to do that.”

However, there may not be much to lose by just making your own prototypes with a free aPaaS sandbox anyway. At the very least, you have the blueprints ready when the opportunity to present your idea arises or if you want to jump ship and start your own company. At best, you become the change your enterprise really needs.

Today’s developers need low-code tools…and maybe a new suit

Fred Churchville Fred Churchville Profile: Fred Churchville
Agile software development, Application development, PaaS

Low-code tools may be a developer’s best friend, according to experienced coders-turned-entrepreneurs in the field. Mark Roemers, founder of the pharmaceutical-centric SCM applications and hardware provider AntTail, successfully used new, low-code tools to help him get his company off the ground, and he has some crucial advice for enterprise-based developers.

AntTail’s job is to produce and maintain both the software and sensors that help users keep track of important pharmaceutical deliveries and make sure that they arrive both at the right time and at the right temperature. But by leveraging the support of a low-code solution provider called Mendix, a Boston-based PaaS provider that is now available on IBM Bluemix  Roemers said he is able to rapidly develop either apps or portals for his customers that can specifically target the precise needs of their customers and integrates with the sensors they produce.

And even though Roemers is an experienced programmer, he still was able to find value in the capabilities provided in free, low-code tools. He admitted that he had not programmed for close to 20 years, but despite that fact — and his initial skepticism — it did not take him long to learn how to use the tool and produce a quality portal. Now he says he can produce a portal in three to four weeks, all without the typical backend support and overhead that is usually associated with enterprise portals.

Does it really work?

Roemers said that there is a steep learning curve for those even those experienced with languages like Java, but that it took only a few weeks to become extremely productive with Mendix’s services. He advised that other developers should look into these low-code tools as a way to create valuable proof-of-concepts without reaching into either their company or personal budget.

“You can get yourself up to speed and knowledgeable … without incurring any costs,” he said. “As a company, you can build a complete application [and] demo it as a portal or an application on a tablet,” adding that his company did not even purchase any licensing fees until they had their first paying customer.

Roemers said that the time spent developing is brought to a minimum with the tool. His entire “team” consists solely of him and one other partner, and they do not even spend the majority of their time writing code or building the apps.

“I spend about maybe 10% of my time programming, and it’s basically adding little stuff that people ask,” he said. “So we do a release about every four weeks.”

Moving out of the dark ages

Roemers strongly believes that better productivity can only come from utilizing better technology, likening old, large-team development processes to the use of dikes for water as opposed to the use of modern water-management technology.

“That’s a bit how we make code. If you’re coding Java or Angular by hand, let’s say, it’s a bit like shoveling a dike,” he said. “Now we use pumps and sand and water and large shovels, large equipment … it’s more efficient.”

Time for a new image?

The other aspect of development that Roemers stresses is the inclusion of coders in business meetings. He believes it’s important that the coder be able to sit in on a meeting, have someone lay out the business needs and have the coder put together a working prototype as the needs are being laid out. Roemers does, however, recognize the fact that this is a change from the usual “image” developers have maintained.

“It also asks for a different kind of programmer,” Roemers said. “He needs to wear a tie, use some deodorant and sit in a business meeting to understand the logic behind the coding that goes on.”

Roemers also stresses the fact that developers need to be able to show some kind of tangible business value that can be achieved with their creation. Without it, he says that developers are almost making an empty promise. A database that can hold millions of records may be impressive, Roemers said, but unless it can serve a specific business function, it can’t be considered very useful on its own.

Maybe developers don’t need to start wearing a suit and tie just yet, but it may be a good time for today’s coders to think about how much they are communicating with those dictating the business needs. Or, in some scenarios, maybe it’s worth considering the option to “jump ship” and dictate your own business needs.

Perfecting the art of deploying iBPMS apps

Portugal Telecom’s implementation of their latest iBPMS tool, SHOP BOX, may be a shining example of how to manage enterprise software change management correctly.

The telecommunications company, which is the largest in Portugal, was featured in our April 2016 Editor’s Choice for the implementation of PNMSoft’s Sequence iBPMS platform. One aspect of the story truly stuck out to me: they were able to push a successful rollout with a technology team that included just four application managers, two coders and one technical support person.

So how does a company successfully roll out a new piece of software to hundreds of locations that serve tens of thousands of customers? With gradual, steady change management.

Determining a plan of attack

According to Gonçalo Mendes, head of retail development and optimization at Portugal Telecom, their team began the project by sorting through 370 “workflows” associated with their shop management and narrowed down a list of what they determined to be the most critical workflows. These 65 “artifacts,” as they call them, became the focus of their Sequence implementation plan.

“They had more than 30 different applications, and more than 400 different processes,” Vasileios Kospanos, marketing manager at PNMSoft said. “That caused a lot of confusion, and they wanted to simplify that by converging all their processes and their systems in something they created [called] ‘SHOP BOX.'”

Keeping it simple…relatively

According to Steve Weissman, analyst and founder of the Holly Group, Portugal Telecom’s success with the SHOP BOX project rests on the fact that they piecemealed their implementation. Portugal Telecom, who’s customer service representatives operate out of 250 unique “shops” that deal directly with customers, began by migrating about 6,000 customers over into the new BPM system. The company, which currently has about 49 of the 250 shops outfitted with the SHOP BOX tool, made sure to gradually increase that number over the year, eventually growing to 20,000 by April, 2016.

“They’re not trying to eat the whole elephant in one bite,” Weissman said. “The fact that they’re taking a longer term view of success dramatically increases the chance that they’ll achieve that success.”

A tangled web of an infrastructure…

Kospanos said that the implementation was not a simple one. Portugal Telecom’s existing architecture made the implementation a challenge, especially since it required coordination between the different vendors and stakeholders that make up Portugal Telecom’s stack.

“The implementation was challenging, and that is also down to a lot of parties being involved,” said Kospanos. “You have Microsoft in one side, Accenture, us with the Sequence [technology] and also Portugal Telecom themselves.”

Yet despite these challenges, the implementation of SHOP BOX has been a success. And Kospanos believes that it is not necessarily because they have a small team that they were successful, but rather that they made the effort to find technology that enabled them to work efficiently.

“You can buy Agile technology, you can buy the latest and greatest,” Kospanos said. “But if you don’t work in an Agile way or in a way that will [at least] make success a possibility, it won’t be successful.”

Enterprises, time to wake up and smell the APIs!

Fred Churchville Fred Churchville Profile: Fred Churchville
API, B2B, EDI Transactions

Enterprises are stuck in the EDI mud, hanging onto old B2B integration technologies. Legacy EDI methods such as value-added networks (VANs) are costing many companies huge amounts of money in service subscriptions when cheaper, cloud- and API-based alternatives are readily available.

That’s the finding of Ovum’s new study, titled “Developing an Agile and holistic B2B integration strategy for digital business success,” which indicated that over half of enterprises interviewed are using in-house or legacy EDI solutions. And more than a third of respondents are using more than three separate solutions for EDI management.

The costs of B2B integration

As I’ve discussed before in a February 2016 article talking about the use of APIs versus traditional B2B integration solutions, many companies find themselves locked in with expensive VAN services — a service whose inefficient data management practices drive up the costs of the service, according to Eric Rempel, CIO at the integrated logistics provider Redwood Logistics. He pointed out that sometimes the EDI VAN service providers that their clients use will translate data into EDI format only to have it translated back to the original XML format once it arrives in Redwood Logistics’ hands. Rempel said that only after showing the company how much this practice was running up costs, they finally abandoned the EDI VAN and began securely sending XML data to Redwood Logistics directly via API-based methods.

The study, which was sponsored by the digital business platform provider Axway, also revealed that even companies that attempt to manage all their B2B integration in-house, using legacy hardware and systems, may not be doing themselves any favors. Ovum points out that “resource-related costs can account for up to 60% of the total cost of ownership for a legacy EDI solution,” and that turning to cloud- and API-based solutions could potentially save these companies immense amounts of money by eliminating certain resource requirements.

Reading the statistics

The study also found some other interesting facts:

  • Today’s enterprise takes an average of 23 days to onboard a new trading partner.
  • Over 25% of respondent enterprises admitted that onboarding can often take more than 36 days.
  • About 10% of respondent enterprises currently utilize cloud-based B2B integration methods.
  • About 18% of respondent enterprises are inclined to use cloud-based B2B integration services under a managed services model.
  • A little less than half of enterprises surveyed currently have a digital business initiative that requires use of APIs, and another 6% plan to implement an API program within the next year.

Two of those points I find particularly striking. If so many enterprises are willing to admit that their B2B integration efforts are severely inefficient, why is it that so many companies still cling to these legacy services and only 10% have moved to the cloud? Furthermore, if so many companies are already pursuing cloud- and API-based business initiatives, why would they not apply those initiatives to such a critical — and expensive — aspect of their business processes?

Where is this going?

“People are testing the waters,” Ken Yagen, vice president of products at the API provider MuleSoft, said. “I think you’ll see the growth. You won’t see the EDI transactions diminish, but you’ll see a growth in API transactions rather than traditional B2B EDI transactions.”

As is often the case in the enterprise world, I’m sure this will simply take time to catch hold. But hopefully cloud- and API-based B2B integration solution providers — and us tech journalists — can make the effort to show these companies exactly how much money they are potentially throwing out the window for these legacy services and methods.

Developer Workforce Initiative: Three steps to generate more talent

Fred Churchville Fred Churchville Profile: Fred Churchville

How the Developer Workforce Initiative will generate more talent with three distinct approaches

The Application Developers Alliance has revealed a three-tier strategy targeting at addressing the critical shortage in enterprise software development talent. According to Jake Ward, president of the Alliance, they plan to work with corporate partners in the Developer Workforce Initiative to implement an immediate, a long-term and a holistic approach to solving this problem.

In an interview, Ward explained what each of those strategic tiers entails and what they hope the Developer Workforce Initiative’s efforts will accomplish.

Immediate

Ward believes that there are number of talented developers who are limited by a general unfamiliarity with large-scale enterprise and the lack of a defined career path that is often found in traditional professions.

To address this issue, Ward said the “immediate” approach involves raising the level of expertise and comfort with large, enterprise systems — mainly through the distribution of easily accessible educational materials and teaching resources. This, he said, will allow developers who may currently be working with small-scale applications in closed environments, such as amateur hobbyists, to become more familiar with the level of sophistication and skills required and pursue a career in developing enterprise applications.

Another aspect of this approach involves creating what Ward called a “professional development career trajectory” that allows developers to create a career plan based on both their interests and existing skills. The group also focuses on connecting talented developers with the companies looking for that expertise.

“We think that as an essential workforce that is growing in importance every day, they should at a minimum be able to plan their own careers,” Ward said.

Long term

The goal of the “long term” approach, Ward said, is to ensure that development career teachings become embedded within elementary, high school and college curriculum. This includes working with educational leaders, government and partners in the Developer Workforce Initiative to create frameworks around developer training and increase the distribution of learning resources.

Bringing development skill training to the class has already been pushed at a government level. Last year, the White House issued a press release announcing the creation of “TechHire,” which is described as “a bold multi-sector effort and call to action to empower Americans with the skills they need,” by working with universities and community colleges as well as utilizing ‘coding boot camps,’ and high-quality online courses that train developers quickly. Programs in Delaware are training students in Java and .Net, and programs established in Louisville, Ky., are working to standardize employer recognition of software development skillsets.

When asked how he feels about the government promoting and providing funding for these developer education programs, Jake said he and the Application Developers Alliance are in full support.

“It’s the language of our lives,” Ward said. “Why wouldn’t we want people to learn it?”

Holistic

The final piece of the puzzle, according to Ward, is the holistic approach: Creating larger appreciation and awareness of the development workforce and profession.
“People need to know that [being a software developer is] one of the top jobs in the country,” said Ward.

Ward said that while the Application Developers Alliance sees growth in the general understanding and appreciation of software development, there is a still a large number of potential developers missing out on career opportunities. Ward fears that these potential enterprise developers either don’t understand there is potential for a viable career in software, don’t know how to access learning resources or believe it is simply too difficult a field to learn about or excel at.

Through efforts driven by the Developers Workforce Initiative, Ward believes the Alliance and its partners can successfully promote awareness and appreciation of the profession and the skills it requires. He hopes this will ultimately result in the increased strength and size of developer workforce over the long term.

Why a big data algorithm belongs on your dev agenda

Jan Stafford Jan Stafford Profile: Jan Stafford

When Liz Rush started her career in software development, working in algorithm programming and the use of algorithms in data analytics was not on her agenda.

“Just the term ‘algorithm development’ frightened me back then, and many developers I meet have the same feeling,” said Rush, developer evangelist for Algorhitmia, an open marketplace which now offers 1,600+ algorithms. Her job is demystifying algorithms, algorithm development and the use of pre-built algorithms to speed up software development projects and enable data analytics.

Liz Rush talks about why a big data algorithm should be on your dev agenda

Liz Rush talks big data and algorithms at the 2016 LWT Summit in San Francisco

I talked with Rush about how shared algorithms eliminate a build-your-own (BYO) bottleneck in the application development process. We also chatted about her presentation, “Your Big Data’s Boring: Let’s Talk about Algorithms,” which she delivered at the 2016 Lesbians Who Tech Summit in San Francisco.

Finding a love for coding

Rush became a software developer through Ada Developers Academy, a non-profit, tuition-free code school for women in Seattle. “That’s when I fell in love with coding,” she said. Before that, she worked in marketing and translation jobs, where she acquired skills that still come into play in her developer evangelist role.

“I do a lot of code writing and producing content, like sample apps,” she said. She also creates demos and presentations that show how to reap the benefits of sharing algorithms between departments within an enterprise.

Why big data algorithms matter

At the LWT Summit, Rush told the audience of 1,500 tech pros how they can use algorithms to get value out of data. “Big data is useless unless you have the tools to do anything with it,” she said. Via algorithms, she explained, developers can see patterns in data of all types, such as images and audio, to classify unstructured data and do other analytics tasks.

Rush also discussed career and community-building opportunities in algorithm development during the LWT Summit. She said the growing algorithm outsourcing movement allows users to pick and choose their algorithms, giving a large number of software teams access to quality algorithms developed by experts.

Until recently, most enterprise development teams built their own algorithms. “Everybody wanted to do it themselves, sometimes just to prove that they could do it themselves,” Rush said. “I understand that impulse, as you can learn a lot from the process.”

But these teams should realize that while a BYO approach to creating algorithms worked pretty well when businesses used fewer applications, today it can limit the ability to rapidly develop new products and services. Applications are evolving rapidly, Rush noted, and shared algorithms help businesses keep their apps on the leading edge.

The value of an algorithm marketplace

Many companies understand they need an algorithm to do a specific task, but acquiring those needed algorithms is not always easy. “Traditionally, they’ve had to take the costly path of building it in-house or hiring an algorithm developer,” Rush said. Via a marketplace, businesses have the less-costly option of choosing pre-designed algorithms rather than reinventing the wheel themselves.

Start-ups, in particular, can benefit for using an algorithm marketplace. “They can get the value from the algorithm quickly without paying to build it or risking building it improperly,” she said. “Sharing algorithmic knowledge is a sure way to improve development practices.”

Tired of support calls? Here’s a thought

Valerie Silverthorne Profile: Valerie Silverthorne

When you’re an IT department of two, with 150 outside sales folks plus 150 people in the building, everything just needs to work.

Too bad that really doesn’t happen very often. And Jesse Davis, network admin for pharmaceutical company Derma Tran (a job he recently left), was reaching the breaking point. The company was using Citrix Xen to run its virtual desktops and between needing an extra layer of virtual desktops to run the virtual apps (which was costly), the map drives failing, restrictions the company couldn’t change and endless errors the tiny IT staff was spending virtually all of their time simply putting out fires.

Davis decided it was time for a change and looked at cloud provider dinCloud and its options for virtual private data centers. Dave Graffia, vice president of sales for dinCloud, explained that simplicity, cost and performance are what brings customers looking for help. “The whole process of building a data center from scratch is just becoming overwhelming now in a way it hasn’t been before,” he said. “There are lots of moving parts, R&D, capital investment and so many layers. Our best customers end up being those people who tried it and then came to us for help.”

Cost of course is also incredibly important. Graffia pointed to a Gartner Group study that showed desktops cost companies $300 to $500 a month. Virtual desktops are of course much less pricey, and using dinCloud, companies can provision or de-provision quickly. And thanks to good tracking, the dreaded “cloud cost creep” shouldn’t be an issue.

“From an IT perspective, the virtual workspace is very easy to use,” Davis said. “Now we take maybe 10 percent of the calls we used to.” In fact, his small team is now able to tackle some other niggling jobs — like email encryption and remote device management — and eventually they’re hoping to redo the camera system around the entire compound.

Choosing a workable solution has changed everything for the IT team, Davis stressed. “It has made the world of difference for us. We’ve gone from being constantly on the phone with the cloud provider to being the Maytag Man.”
