This document discusses using virtual desktop infrastructure (VDI) to provide development environments in the cloud. It describes the challenges that agile development practices pose for traditional on-premises IT environments. The document then introduces DevFarm, a solution that extends VDI capabilities to meet developers' needs through self-service access to customizable environments on demand. It provides examples of scenarios that are suitable for DevFarm and describes DevFarm's architecture and implementation on AWS. Finally, it analyzes the total cost of ownership benefits of using DevFarm on AWS compared to maintaining on-premises development environments.

Dev vs. IT
Development Team Need IT
5 New Contractors are joining next
week to meet the new timelines
promised to customers.
Decided to follow a Feature Based
Development model.
Developers need to work in
parallel on multiple projects
Support teams need access to
multiple versions
Geographically distributed teams
working in parallel
5 new workstations with all software
setup in less than a week
Multiple development
environments in parallel
Multiple environments for each
developer
Separate environment has to be
maintained for each version
Shared dev environments to work
collaboratively
Need more time
No budget
No space
No IT Support bandwidth
Can’t allow – Security issues

6. US | UK | BENELUX | ME | IND©1996-2016 Aspire Systems, Inc.
Agile Needs
The development environments (as a stack) should be available on-
demand at the disposal of developers
Team should have self-servicing capability to create their
(multiple) development environments without any
intervention from IT teams
Each team should be able to make progress without
any dependency with other development teams
Teams should be able to easily share/access common
environments, easing the collaboration efforts
Templated environments should be used across the teams for ensuring
consistency

Virtual Desktop Infrastructure (VDI)
 Centralized Management of Desktops
 Efficient power consumption
 Access anywhere, anytime
 Secure

VDI Fitment for Development Workload
Typical
Desktops
Development
Environments
VDI Solutions mostly applicable for vanilla
workstations/desktops
Desktops typically contain standard set of
software
Software configurations don’t change often
Offers excellent options for managing the
desktops but less support on the desktop
customization
Not designed for sharing of desktops
Follows a workflow for approval and
provisioning of desktop
Dev. Environments are typically complex in
nature and has interdependencies
Wide range of tools might be required
depending on the technology stack
Frequent changes in versions of the
tools/libraries used in development
Requires medium/heavy customization of
the desktop to support the dev technology
stack
Most often will require sharing with other
developers for co-development
Needs self-servicing capabilities to
launch/terminate at will

What is DevFarm?
Deploys Cloud automation for addressing development
environment related complexities
Extends VDI Solution to meet the needs of Development
environment
Implemented on cloud for cost savings; no CapEx
Offers Self-Service portal to developers, along with the access
control to IT
Supports custom rules for usage, configuration, cost limits, etc.
Monitoring dashboards and automated alerts to keep the budgets
under control

Scenario #1
Scenarios Suitable for DevFarm
Companies that deal with multiple parallel releases within a single application. In this
case, each team can have it’s own dev environment without affecting other tracks.

Scenario #2
Leverage a task based approach for developers. Developers can handle multiple tasks
across different dev environments. This allows Companies to move away from “effort
per release” to “effort task per release”

Scenario #4
In Support, where multiple older versions of the products have to be maintained. Developers can
fire up the version of dev environment to be worked, complete the work (bug fix, etc.) and remove
the environment. This approach tremendously increases the productivity of support teams.

Scenarios Suitable for DevFarm
Cross team working – where you need the flexibility to have the developers work on
multiple projects. Instead of providing them 3-4 laptops/desktops – you can simply
provide them access to as many environments as required.
