Quick Prototyping with LXC and Puppet

The object for this presentation is to inform people about how they can better use container technologies to save time and resources compared to virtual machines, which in turn makes things such as continuous integration testing faster, and which can save them money on unnecessary resource usage. You'll also be able to understand the difference between Docker and LXC, and when it appropriate to use either tool.

In addition, He'd like participants to leave the session with an understanding of what configuration management is, and how it can be used to automate or simplify some of their day-to-day activities.

He would also like to leave the participants with a basic understanding of how Linux cgroups and LXC work, and the ability to modify LXC templates to better suit their environment.

Microsoft Azure Infrastructure Services foundation (sponsored)

This session will give you a better understanding of the basics of configuring Microsoft Azure Infrastructure services including Microsoft Azure Virtual Machines and Virtual Networks.

Building the foundation for Microsoft Azure Infrastructure as a Service (IaaS) is mostly undermined and can later cause trouble if not planned correctly. Learn about the essential Microsoft Azure Infrastructure foundation concepts in this session & a tour of the features that make up the Microsoft Azure Virtual Machines and Virtual Networks offerings, which collectively make up Microsoft Azure's IaaS.

Scale anything with haproxy

• Introduce haproxy as a webscale load-balancer capable of scaling any workloads
• Demonstrate haproxy as a solution to scaling webservers, webservices, DB and discuss just about scaling any specific technology the audience wants to discuss
• Discuss load-balancing strategies with an example
• Discuss specific architecure solutions for magento, wordpress, drupal and elucidate how even a structureless/frameworkless app can be scaled
• Introduce inotify based sync mechanism as an alternative to shared storage for use in load-balanced webservers
• Introduce to security features of haproxy like rate-limiting and blackholing techniques to avoid webservers from being overwhelmed by specific attacks (should not be taken as DDoS protection schemes)
• Demonstrate any audience query on load-balancing with an example (time permitting, we can do a full deployment)

Building Orchestration and Configuration with Ansible

Ansible is a an agentless orchestration tool which does more or less what Puppet and Chef do. It relies on OpenSSH for transport and YAML for creating playbooks.

Playbook is essentially a list of rules which are applied to a (set of) server to put them in desired configuration.

In this talk, he will show how to execute ad hoc commands on one or more servers as well as create simple playbooks. I will also talk about the best practices to use Ansible in order to get maximum benefit out of it.

Lastly he will share their own story where Ansible really helped them in deploying Virtualization (Xen) Servers vs Pupppet whose compatibility gave them really hard time.

When the Internet Bleeded

The talk will talk about various TLS / SSL related bugs that are identified in past year.

• HeartBleed
• GNUTLS Bug
• Apple SSL Bug
• Lucky 13
• BEAST
• CRIME

These bugs have shaken the core premise of Secure communication. The talk will focus on bringing a basic understanding of these issues to the administrators or developers. Besides this the talk will also focus on some burning questions that are now raised in wild. Such as

• How secure are secure Socket Libraries?
• Is opensource code really secure?
• Is it really true that "given enough eyeballs, all bugs are shallow"?
• Should we move towards higher abstract languages?

and most important: What it really means for a Administrator / DevOps person

•  Funnel Proposal

Scaling databases with a database abstraction layer

The objective of this session is to discuss an architecture to scale and manage the database tier by introducing a database abstraction layer. We will discuss various challenges of database scalability and then discuss few solutions.

He will be taking few references from the Facebook's WebscaleSQL project, Google's spanner paper and MySQL proxy.

•  Funnel Proposal

Testing Infrastructure Code using Test-kitchen, Docker and Chef-Zero

With more and more use of automation for environment provision it has become very important that TDD is followed for Devops/Infrastructure code as it is followed application code.

The Session will describe how chef recipes,databags etc can be tested in local dev box environmnet before they are uploaded to chef server and used in deployments.

This session will aim towards using the combination of Test-kitchen gem with kitchen-docker plugin and chef-zero. This will help understanding test driven development of devops code in an private environment without interrupting the working environment.

Scaling to 2000 request per second with MongoDB

The Objective of this session is to showcase my experiences with developing, scalling to 2000 req/sec and performance testing the website for one of the biggest media houses of the UK.

Continuous Multi-stack Deployments on Cloud using Docker

Overview of how docker can be integrated with Jenkins to deploy and configure multi-stack applications on clouds.

Docker provides a mechanism to lift, shit and fit an environment across various stages of software delivery cycles. By integrating with Jenkins, Docker provides a quick and repeatable software delivery on Cloud.

DDOS mitigation @flipkart

DDOS Attacks have been on the rise all over the world. This include Volumetric i.e. Layer 4 TCP / UDP and Application i.e. Layer 7 HTTP, MySQL.Volumetric attacks are all about muscling out the attacker at the upstream / scrubbing farms. The same cannot be done for Layer 7 attacks.

Traditional DDoS systems cannot catch Layer7 attacks as they all work on layer 4. There are inline solutions such as WAF, etc which looks at traffic and make profiles like IDP. But at scale all that becomes resource intensive and affects latencies. At flipkart we devised a solution that looks at logs from various layers, detects patterns and automatically blocks the attacker at the perimeter.

In this talk we explore various types of attacks and what Flipkart does for mitigation.

Aim of this talk is to describe the current best practices and software to use when creating an auto scaling infrastructure.

Mesos: Cluster management framework and it's role at Shopify

As applications get scaled across multiple server, there is a need to maximize resource utilization, minimize data replication across different applications by allowing applications/frameworks to share data centre. The talk will introduce Apache Mesos, a framework for sharing resources across nodes in a data centre along with details about it\u2019s architecture. It will also cover how Shopify uses Mesos to power its infrastructure and scale on demand.

Tsuru - Serve it yourself.

Tsuru is a open source PAAS system. It helps Sysads to create generic infrastructure and platform in place which comes into life once the developer pushes the code. This self servicing mechanism will be useful to reduce the layers like config management. Since Tsuru leverages the features of docker, it supports both - isolation and scaling. For not so adventurous sysads, who are not ready to risk a software which is in heavy development in production, tsuru can be integrated with the build system, the testing infrastructure can be containers which can be spawned and stopped as needed.
