The site visits include stops at Square (the payments startup founded by Twitter co-creator Jack Dorsey), WeWork Soma (an amazing co-working space) and Pivotal Labs (leaders in Lean and Agile consulting), along with one more super-interesting location we’ll announce shortly. Thus we reduce the risk of deployments.
Lessons Learned by Eric Ries Monday, June 15, 2009 Why ContinuousDeployment? Of all the tactics I have advocated as part of the lean startup , none has provoked as many extreme reactions as continuousdeployment , a process that allows companies to release software in minutes instead of days, weeks, or months.
Lessons Learned by Eric Ries Monday, December 28, 2009 Continuousdeployment for mission-critical applications Having evangelized the concept of continuousdeployment for the past few years, Ive come into contact with almost every conceivable question, objection, or concern that people have about it.
I hope to show why lean and agile techniques actually reduce the negative impacts of technical debt and increase our ability to take advantage of its positive effects. Yet other agile principles suggest the opposite, as in YAGNI and DoTheSimplestThingThatCouldPossiblyWork. Reconciling these principles requires a little humility.
Lessons Learned by Eric Ries Monday, February 16, 2009 Continuousdeployment with downloads One of my goals in writing posts about topics like continuousdeployment is the hope that people will take those ideas and apply them to new situations - and then share what they learn with the rest of us. Thanks for the comments.
When I first encountered agile software techniques, in the form of extreme programming , I thought I had found the answer. I explained it to people this way: agile lets you make the trade-offs visible to whole company, so that they can make informed choices. Even worse, agile wasnt really helping me ship higher quality software.
It’s important to invest in good architecture so that your website will scale once customers arrive. If you make that investment, and then customers arrive, and the site stays up, most companies will reward the people who built the architecture and, thus, prevented the scaling problems. Why do they harbor that paranoia?
Wed never heard of five whys, and we had plenty of "agile skeptics" on the team. By the time we started doing continuous integration, we had tens of thousands of lines of code, all not under test coverage. It seems your cluster architecture is one of the key architectural constraints making continuousdeployment possible.
If youre trying to design an architecture to maximize agility, how can that work if some people are working in TDD and others not? That means knowing whats written and whats not, what the architecture can and cant support, and how long it would take to build something new. But along the way, something strange happened.
The six key attributes spell ABCDEF: Agility. When talking about their past experience, candidates with agility will know why they did what they did in a given situation. To probe for agility, you have to ask the candidate questions involving something that they know little about. At the time, I was a die-heard Java zealot.
I suggested that we change the underlying architecture of our UI system so that the artists would be able to build their own UI pieces themselves and then integrate them into the product without requiring new code every time. Case Study: Continuousdeployment makes releases n. The engineering team wasn’t happy either.

Lessons Learned by Eric Ries Sunday, January 4, 2009 Sharding for startups The most important aspect of a scalable web architecture is data partitioning. So far, this is just a summary of what all of us who have attempted to build web-scale architectures considers obvious. Support multiple sharding schemes. Easy to understand.
In addition to presenting the IMVU case, we tried for the first time to do an overview of a software engineering methodology that integrates practices from agile software development with Steves method of Customer Development. Case Study: Continuousdeployment makes releases n. Ive attempted to embed the relevant slides below.
I know them right away - we can talk high-level architecture all the way down to the bits-and-bytes of his system. When the architecture needs modifying - why do we need a meeting? Building a good application architecture is not just coding. Its common to find a hacker at the heart of almost any successful technology company.
We wanted an agile approach that would allow us to build our software architecture as we needed it, without downtime, but also without large amounts of up-front cost. You can also download our presentation, " Just-In-Time Scalability: Agile Methods to Support Massive Growth." Case Study: Continuousdeployment makes releases n.
And as Kapor himself points out, the core ideas have even older origins: The Roman architecture critic Vitruvius advanced the notion that well-designed buildings were those which exhibited firmness, commodity, and delight. Case Study: Continuousdeployment makes releases n. We owe a lot to this seminal document. Expo SF (May.

Even though some aspects of the product were eventually vindicated as good ones, the underlying architecture suffered from hard-to-change assumptions. Even a great architecture becomes inflexible. This is why agility is such a prized quality in product development. Case Study: Continuousdeployment makes releases n.
The engineering team has decided its reached a breaking point, and is taking several weeks to bring it up to modern standards, including unit tests, getting started with continuous integration , and a new MVC architecture. On the other, they already have a team fully engaged on making their product architecture better.
