How to Work in Tech and Not Wreck the Planet

The world is changing. The past five years have been the warmest since records began. Human activity, including the IT industry, is driving worrying climate change. The cloud gives us dazzling computational possibilities, and … potentially uses a lot of energy.The beauty of the cloud is that it makes it easy to run code, virtualised and scheduled for efficiency... but it doesn't provide any guarantee that what's running is useful.  As climate change accelerates, where do we, as engineers, fit in? Are we part of the problem or part of the solution? How do we balance the needs of people against the need of the planet? Or can they be aligned? This talk discusses some of the trade-offs and provides a roadmap to figuring out the right thing.

PANEL DISCUSSION

Connecting the Dots: Considerations in Modern Software Development

At QCon, we get the opportunity to hear about new and interesting ways to tackle the technical challenges we face. We leave energized and eager to apply some of the solutions and alternatives that we’ve learned with our own teams. However, it can be difficult to connect the dots between the compelling stories we hear about technological transformation with new technology and the work we do day to day.

Join some leading experts in Socially Conscious Software to share your challenges, hear from others who have similar challenges, and collaborate together on ways to take what you’ve learned at QCon back to work.

7 Ways To Fail at Microservices

We all know the promise of microservices - organizational, agility, decoupling, pizza lunches, autonomy, fewer meetings. Some organizations actually achieve this. Others … don’t.

It turns out dividing an application up across multiple containers isn’t enough. Distributed is not a synonym for decoupled. A decomposed application may just be a health hazard. Cloud-native spaghetti isn’t something you want. Continuous deployment doesn’t mean ‘every six months’. And have you spoken to your release board and QA team about all this?

Here are some of the anti-patterns Holly will discuss:

  • The murky goal
  • Microservices envy
  • Cloud native spaghetti
  • The enterprise hairball, or “forgetting the back, front, and glue”
  • The not-actually-continuous continuous integration and deployment
  • The someday automation
  • The not-actually-cloudy cloud

PANEL DISCUSSION

Present and Future of the Microservice Architecture

When thinking about a microservice architecture there is so much to consider! The topic is broad, and sometimes the expertise needed to understand parts of it are deep. This can make them a pretty daunting subject. Lucking, QCon is at hand!

In the final slot of the microservices track, we'll be bringing together Microservice experts to help give into the complexity. Hosted by Chris Richardson, our panelists include Glenn Engstrand, Hold Cummins, and Dave Farley. The four will be reflecting on topics raised throughout the day in the Microservices track. You won't want to miss it.
