Projects and Case Studies
WhiteHedge
CLIENT IN THE MEDIA DOMAINDesigning and implementing the DevOps strategy to align with the business vision of introducing a new device in the mobile devices market.
WhiteHedge SolutionØ Created VPCs in two different
AWS region with multi-AZ configuration
Ø Configured Highly Available NAT servers for inbound and outbound traffic
Ø Created auto-scaling policies based on CPU Utilization and inbound traffic through ELBs
Ø Defined policies for periodic patching & updates to base AMIs
SituationØ Worldwide leader in consumer electronicsØ Leader in manufacturing mobile devicesØ Introduction of a new tablet in the market
ChallengeØ Building AWS infrastructure to support a product
launch in 40 countriesØ Creating a CI, CD Pipeline for a node.js serverØ Setting up auto-scaling infrastructure to support
heavy traffic during the shopping season

Value Addition
WhiteHedge
Ø AWS, EC2, CodeDeployØ Jenkins, DockerØ NodeJS, Python, Bash
Ø Created CloudFormation Templates for quick future deployments for new regions
Ø User AWS CodeDeploy to deploy server on AWS
Ø Monitoring using DataDog & Operational support integration with PagerDuty
Ø WhiteHedge offered DevOps consultation, implementation, though leadership and helped in taking strategic decisions related to infrastructure design.
Ø Infrastructure was an important aspect to support the new device in the market, in order to autoscale and support the variable and unknown load in production.

AMAZON ELASTIC CONTAINER SERVICEAmazon EC2 Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster of Amazon EC2 instances.
WhiteHedge SolutionØ We explored a number of Docker
orchestration tools: Kubernetes, Docker Swarm and Amazon ECS.
Ø ECS lets you launch and stop container-enabled applications with simple API calls
Ø Allows you to get the state of your cluster from a centralized service
Ø Gives you access to many familiar Amazon EC2 features.
Ø No need to maintain any software to manage cluster on our side as ECS is a free service.(If you are using EC2 instances)
ProblemØ How to orchestrate and autoscale Docker
containers on Amazon EC2?
ChallengeØ We run application inside docker containers on
EC2.Ø We automated docker image creation using
Jenkins and scripts.Ø We automated deployment using Amazon
CodeDeploy. Ø However autoscaling docker images on EC2 is an
open problem today. Ø How could we orchestrate and autoscale docker
containers in production?

APPLICATION PERFORMANCE MANAGEMENTApplication Performance Management (APM) is the monitoring and management of performance and availability of software applications.
WhiteHedge SolutionØ We setup and configured the monitoring
solution for the client using DatadogØ System monitoring and Application
monitoringØ We setup automated alerts in the form of
phone calls, emails and chat notificationsØ Alerts were triggered when the
application went down or was unresponsive, when the system parameters looked unhealthy (CPU, Memory, etc.) or when the application produced too many errors.
Ø The application health was shown graphically on the Datadog dashboard
ProblemØ Getting an insight into how the application
performed was needed to take key business decisions
ChallengeØ While the client developed and continuously
deployed the software, there was no feedback mechanism in place
Ø It was important to know if the application was up and responding
Ø We had to design a mechanism which would help in debugging issues in the system
WhiteHedge
APPLICATION MONITORINGApplication monitoring is a process that ensures that a software application processes and performs in an expected manner and scope.
WhiteHedge SolutionØ We realized the need to do code
augmentation to gather the HTTP request processing time metric.
Ø We had to ensure that this code augmentation does not affect the overall performance of the system.
Ø We chose to do this using Datadog. Ø Our application was in NodeJS. We used
module.Ø The metrics were sent from code using
the node-dogstatsd module to local Datadog agent using UDP.
Ø Local Datadog agent sent the metrics to Datadog server using Python.
Ø The Datadog UI and scripts were used to display the metrics in the desired format
ProblemØ Our client wanted an insight into how the
application was performing in terms of the time needed to process an HTTP request.
ChallengeØ Many monitoring solutions offer out of the box
support to track HTTP response times by sending dummy HTTP requests to the system.
Ø Our challenge was to come up with stats which give the response times for each real (production) request into the system.
WhiteHedge
MONITORING USING ZABBIXOpen source and enterprise-level software designed for real-time monitoring of millions of metrics collected from tens of thousands of servers, virtual machines and network devices.
WhiteHedge SolutionØ System monitoring plays a great role in
offering clients a complete, robust solution to their needs.
Ø After research and testing, WhiteHedge decided to utilize Zabbix as the backbone of their monitoring services.
Ø Using Zabbix the WhiteHedge team is able to detect issues quicker and reduce the response times for failed services and applications.
Ø Fully customized alerts, specific to each server/ service monitored have been implemented by the WhiteHedge team to maximize uptime for their clients’ environments.
SituationØ Our client was looking for an easy-to- set-up
and user-friendly monitoring software, preferably on Linux platform with back-up support available 24/7.
Ø And the software still had to have the capabilities to implement custom checks.
WhiteHedge
CLOUD MIGRATIONMoving data, applications or other business elements from on premise to cloud or from one cloud environment to another.
WhiteHedge SolutionØ After studying the existing architecture and the business
requirements WhiteHedge proposed a cloud-based
architecture which leverages the Amazon’s Elastic
Compute Cloud (EC2) and other associated services.
Ø WhiteHedge applied Phase Driven Approach to Cloud
Migration
Business ChallengeØ Physical hardware components rapidly
approaching end of life.Ø Increasing downtime due to network failure in
data center. Ø Increasing operational expenses year over
year.
Ø Cloud experts helped our client to migrate to the
AWS cloud without downtime.
Ø WhiteHedge helped our client to keep the cost
structure at low level.
Ø WhiteHedge put focused efforts that resulted in
efficient turnaround with qualitative delivery.
Ø Integration of third party tools such as Puppet to
get work done.
