In today’s technology world, operational efficiency is pivotal. It is time to focus on measuring, learning and improving different aspects of infrastructure scaling and development cycles. Not to forget the the culture of DevOps and team dynamics.

Rootconf 2015 focuses on four key aspects of DevOps and scaling infrastructure: virtualization, managing infrastructure at scale, new technologies, and team management.

Target audience:

  1. Rootconf is aimed at DevOps, CTOs, and teams and companies.
  2. Organizations developing a Continuous Integration and Continous Deployment strategy. You will get a headstart by attending Rootconf.

Conference and workshop topics:

  1. Virtualization.
  2. Managing infrastructure at scale:
    • Scaling processes for enterprises – log monitoring, security, data management.
    • Scaling tools for enterprises – such as using Graphite, logstash and other tools at scale.
  3. Upcoming technologies such as Salt.
  4. Team management / DevOps as culture.


This year’s edition spans two days of hands-on and conference. We are inviting proposals for:

  • Full-length 40 minute talks.
  • Crisp 15-minute talks.
  • Sponsored sessions, 40 minute duration.
  • Hands-on Workshop sessions, 3 hour duration

Selection Process:

Proposals will be filtered and shortlisted by an Editorial Panel. We urge you to add links to videos / slide decks when submitting proposals. This will help us understand your past speaking experience. Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled will help the Editorial Panel better judge your proposals.

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the theme of the conference, and to help the editorial panel build a strong line-up for the event.

We will notify you about the status of your proposal within two weeks of submission.

There is only one speaker per session. Entry is free for selected speakers. As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. HasGeek will provide a bursary to cover part of your travel and accommodation in Bangalore. Bursaries are limited and made available to speakers delivering full sessions (40 minutes or longer).

Commitment to Open Source:

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Important dates:

Last date for submitting proposals: 15th April

Shortlisting process: 31st March onwards

Pre-conference workshops: 13th and 14th May

Conference dates: 15th and 16th May


Rootconf will be held in the MLR Convention Centre, J P Nagar.

How to Create a Low Cost, Self Healing & Immutable Infrastructure using AWS EC2 Spot Instances

Submitted Apr 10, 2015

Reduce AWS bills significantly, automate maintenance using Auto Scaling & understanding spot instance failover


AWS is a leading cloud services provider and it has millions of users. The major component of

AWS usage & subsequently billing are EC2 Instances. Although the cost of EC2 instances goes

down if one purchases reserved instances, there is another feature for EC2 instances which is

rarely used by customers. This session will guide you on how to use it.

AWS provides spot instances which are the unused compute resource of AWS infrastructure &

can available to customers at a very low price. Prices are governed by market dynamics of

demand & supply with users putting up bids to request these instances. Average market prices

can be ⅛th to 1/10th of normal instances, and when users’ bid prices exceed market prices

these requests are fulfilled.

Only catch is, AWS can terminate allotted instances with little to no notice if A) market price

exceeds bid price or if B) the spot pool of your instance type is reduced due to increase of

demand for normal instances.

These are the risks why many users stay away from Spot instances. This session will provide a

solution to address these risks which actually reduces costs without compromising performance.

The solution includes deploying Auto­Scaling Groups setting attributes like Launch

Configuration, VPC & Subnet, Number & Composition of instances, Notification settings and

Scaling policies.

This session will have a demonstration of deployment of Auto­Scaling groups & attributes,

Launch of instances and simulated termination to display its Self Healing capability. I’ll also discuss two

real situations in detail.

Having managed DevOps for various clients, deploying this solution has produced positive

results of reduced AWS bills & infrastructures capable of healing themselves.

Speaker bio

I am a Senior Consultant at CodeIgnition and manage DevOps, Cloud & Continuous Delivery projects. With 3 years of hands on experience & many more as a code connoisseur, I am passionate about Continuous delivery, Cloud, Infrastructure & Automation. I gave a 15 minutes talk at Rubyconfindia, about a very similar topic. This talk will be a detailed version of that talk. I am using all the concepts, I wanna talk about, in the architecture of a continuous delivery platform I am developing,
