In this talk, we will cover the ways to break down a monolithic large scale application into pieces.

We will discuss WHY we did it and how we benefited from it.

This talk will be Ruby Oriented mostly, but anyone working on a mid-level and higher scale application will probably find it useful.

The talk is 100% anchored in real life event, this is the real life story of an application as it traveled from the classic monolithic rails application and the journey to becoming slim and light pieces of code.

There's a bit of everything, from code decoupling techniques, avoiding duplication, configuring and deploying using CHEF and more.

As a fast growing company Wix R&D doubles every year. In this talk I will describe how we structured our R&D division, what we are doing to build and keep an "A" team of developers and our dev centric and quality based culture that supports innovation.

Over the last couple of years the term "DevOps" has become so ridiculously overloaded: an industry trend, a cultural shift, a set of methodologies, a set of tools, an organizational function, ad infinitum. Over the last few years I've gone through a circuitous journey through different roles and functions within several R&D organizations, and would love to share my perceptions on DevOps from a software developer's perspective -- and maybe provide a few insights into how it could be done better.

I messed up and I'm proud. Come and present your most glorious chaotic moments at the Hall Of Shame session on the second day. During this hour you get 3-5 minutes to tell us about your most original and funny (or sad) bugs. It's as much about entertainment as it is about learning. Don't be shy and prepare your bug stories to share with us. We have worthy prizes for the best stories

and a small token for every participant!!!!!!11

In the shift towards NoSQL DBs (let it be document based, key-value, or column-oriented to touch a few) it is quite common to forsake some hard-learnt lessons and best practices from the relational databases domain.

In this session, we will discuss some common data related dilemmas when scaling up server side applications, and explain why we choose to use PostgreSQL’s JSON support over MongoDB in order to scale up.

We will touch on various considerations when choosing the most suitable database solution for our need, such as:

Data migrations, schema upgrades, forward and backward compatibility considerations

We will also briefly cover PostgreSQL’s JSON support, and describe some best practices we’ve adopted for using it.

Creating quality-software is fundamental for building quality-products. And yet we find ourselves struggle with code that is hard to maintain and extend, a code that is unreadable, code-duplications and other code-smells. We embrace the phrase “If it works - don’t touch it” while we let our code-base become more and more patched.

In this talk I will try to explain the importance of the code-review process in an agile environment. I will explain how it improves the code-quality and how it helps in increasing productivity. I will talk about the importance of code-review as a knowledge-sharing tool and its advantages for both the individual team-members and the organization. I will also demystify some of the misconceptions about code review and explain how to start and how to make it right.

אורי, נתי ורן מתאחסנים ב Flash

Flash - העתיד של טכנולוגיות האחסון?

מהיר, ללא בעיות של גישה ישירה, וללא רכיבים פיזיים כמו מחטים.

ואפשר גם לוותר על בלום פילטר..

בסיסי נתונים הרצים מעל Flash יכולים לוותר על אופטימיזציות רבות ולהוריד את רמת הסיבוכיות

מנגנונים כמו Write Ahead Log יהפכו לנחלת העבר

הנחה שמשתנה - מהירות הרשת גדולה ממהירות הדיסק? כבר לא עוד

Latency numbers every programmer should know

Rocks DB - בסיס נתונים לדוגמא מעל Flash, והיסטוריה קצרה שלו.

השוואה בין טכנו' אחסון שונות במספרים.

הקובץ נמצא כאן, האזנה נעימה ותודה רבה לאורן אפרתי על התמלול

In this talk I will describe how we can write a high performance client / server in C++ with maximum utilization of SMP architecture on one end, and still maintain a very simple programming / troubleshooting code model with maximum productivity.
The solution is based on an open source library called Mordor, based on pseudo-synchronous model (asynchronous under the hood).

This model allows us to write Thread-like code (called Fibers, very similar to goroutines in GO), and still gain the asynchronous benefits. As a benchmark I will compare it to the naive approach of writing using the Callback code model, yielding non-maintainable code.

Today's Devops ecosystem consists of diverse set of tools, configuration management (Chef/Puppet), remote execution (Fabric, Capistrano), monitoring and central logging all used against a large number of systems (optionally) spread on multiple hypervisors (AWS, vCenter, Docker, Proxmox etc..),

All these tools work great but don't give us a cohesive system to work with, we still need to:

Celestial comes to fill this void, it uses well known best practices from actual field work:

In this talk we will cover Celestial and see it action.
